Ask Sword

"yes."

Li Ang nodded.

"Xi Yangyu likes to follow others, but he should not dare to lie about enrolling in the academy."

Yan Yundang pondered and said: "Then what are your future plans, Doctor Li?"

"The junior still wants to give it a try."

Li Ang said: "If you don't try it, you will still be a little unwilling."

"good."

Yan Yundang nodded and said: "But even if you don't pass the exam, don't be discouraged. The Zhongsiyuan of the Ministry of War is still open. I will just write a letter when the time comes."

"Then I would like to thank the Duke."

Zhongsiyuan is an institution for the Ministry of War to teach the way of practice. It also teaches talisman, art, sword, and reading, but more of it is body training.

Since Yan Yundang was weak and couldn't stand for a long time, Yan Lin asked someone to help him back to the house to rest, and he personally sent Li Ang out of the Duke's mansion, thank you again.

After Li Ang returned to Huaidefang Hotel, early the next morning, the old housekeeper of Duke Yan's Mansion came to visit in a carriage, saying that Yan Yundang's condition had improved significantly, and he was able to eat.

In order to express my gratitude, I will present 10,000 flying coins to Li Ang.

Li Ang insisted on accepting only 4,000 guan of which - at the beginning, the reward posted on the public notice board of the city gate by the government of Yan State was 5,000 guan.

The old housekeeper said that 10,000 Guan was the amount set by Yan Yundang and could not be changed. In the end, Li Ang couldn't hold back, so he had to make a compromise.

Li Ang accepted 4,000 guan flying coins, and the remaining 6,000 guan were converted into various objects of equivalent value—that is, special alloys, jade, wood, minerals, and blank talisman papers were occasionally sold in Chang'an Auction House.

Different materials are an important part of practice.

Special alloys and woods can make flying swords,

Jade and minerals can assist spells,

Talisman paper made of different materials has different manifestations of the power of talismans.

Even for a martial artist who refines his body, medicine, animal blood and even other materials are also used to sharpen his muscles and bones.

Six thousand guan, say more or less, say less or less,

However, the several private auction houses in Chang'an all have the background of Zhen Fusi. They have many rules and are only open to familiar monks. Ordinary people can't buy things with 6,000 coins, or they have to buy at a higher price.

Li Ang said that he wanted to use those materials to try to make his own medical equipment, so he didn't seek more, he didn't seek refinement, he only sought miscellaneous.

The old butler didn't directly boast and agree, but said that he needed to go home and ask Yan Yundang and Yan Lin for instructions.

That night, Yan's carriage came to Huaidefang Hotel again, and several large boxes were removed from the carriage.

In each box, according to Li Ang's requirements, various materials were packed in different categories. The total price is exactly six thousand guan.

Of course, this is the price for Yan Yundang,

Ordinary monks or school disciples who have just entered the school want to buy at least 50% more. If they go to the Chang'an ghost market, the price will even be doubled.

The ghost market refers to a huge cave system composed of dozens of underground rivers, forty miles to the east of Chang'an City. There are waterfalls, lakes, mountains, caves.

There are often people from various religions hiding in the depths of the ghost city, fugitives, wanted monks who defected, bandits who have stolen goods and need to get rid of them, and black market merchants who are desperate for money.

They formed an underground kingdom under Chang'an, where they sold all kinds of strange goods and exchanged what they needed.

Even dangerous monsters and monsters can be sold with a clear price tag. Many forces are intertwined, forming a vast network of interests.

And when the government tried to launch a clean-up campaign,

These people would sneak into the intricate underground river and flee away.

The interior of the cave is deep and narrow, with complex terrain, and hundreds of underground rivers, with countless entrances and exits like honeycombs.

In the former Sui Dynasty, someone from the Academy once threw a hundred painted wooden boat models into the underground river, and the furthest wooden boat even appeared in Poyang Lake, 1,200 miles away.

Moreover, due to the irregular fluctuation of the underground river, the river often raids, diverts, and even collapses.

As a result, the map will become invalid every once in a while, and it is difficult for the army of Yu State and the monks to enter and destroy it.

The Zhen Fusi has no choice but to protect the underground river from being destroyed while completely destroying the ghost city. The underground river extends in all directions. If someone puts a strange poison into the river, the consequences will be extremely serious.

They had no choice but to send troops to guard the exits of the most important caves on the surface, and the two sides reached a certain tacit agreement.

As long as the people in the ghost city don't go too far and do things like sell people on the surface, the Zhen Fusi will not easily go down into the cave.

After Li Ang got four thousand guan flying coins and various materials worth 6000 guan, he first leveled Kangfang, settled Jiao Cheng's account before, and destroyed You Duzhi's slave status.

Song Shaoyuan and You Duzhi were very grateful for this, and insisted on returning the 5,000 guan to Li Ang—Song Shaoyuan still had some money left, and You Duzhi also saved about 2,000 guan, but Li Ang refused.

For the sake of this money, Aunt Song, who is far away in Weizhou, can't send money here.

Let Song Shaoyuan and You both know that they should live a good life in Chang'an's Fangshi first - there will be a Jinshi examination in Chang'an in February next year, and they are all coming. You might as well wait for Song Shaoyuan to finish the Jinshi examination next year before making plans.

After dealing with all this, there are only four days left before the final exam in the academy.

In Huaidefang Hotel, Li Ang looked at the dazzling array of materials on the table, and murmured: "If this doesn't work, then we can only go to the ghost market to try our luck."

"Master,"

Chai Cuiqiao poked her head curiously, "What are you going to make with these things?"

"antenna."

Li Ang smiled and said, "The antenna that can transmit spiritual energy."

He brought a thick blank booklet, put it on the table, prepared the inkstone, ink, and pen,

Then he took a few steps back, picked up the first material - the purple Dushan jade, held both ends of the jade with both hands, held it flat in front of him, and silently recited the text of "Shangqing Inspiration Chapter".

As in the previous test, whenever Li Ang drew spiritual energy into his body, his brain would tingle slightly.

This should be what Xi Yangyu said, the hexagram image of the broken sword.

"Without holding any material, the pain level is 1."

"When holding the purple Dushan chalcedony, the pain level is 1.3."

Li Ang put down the Dushan jade, wrote two lines on the booklet, and then picked up the second material, a small piece of Shenyin wood from Youzhou. Just like before, recite the "Shangqing Inspiration Chapter" silently, feel the degree of brain tingling when the spiritual energy enters the body, and record it in the book.

"Youzhou Shenyin Wood, pain level, 1.2."

Li Ang tested different materials one after another, taking a break every once in a while.

Chai Cuiqiao watched from the side with her eyes wide open, and gradually understood as she watched, "Master, are you recording the degree of pain when holding these things?"

"Um."

Li Angfeng nodded lightly, and explained casually: "Every item in the practice world has the saying of 'the nature of things'.

Different substances have different affinity for the aura of heaven and earth.

For example, pure gold and thousand-year-old peach wood have a higher affinity for the aura of heaven and earth than ordinary stones.

The monk poured a certain amount of spiritual energy into the pure gold and the thousand-year-old peach wood, which can easily suspend them and move in the air according to their thoughts.

However, with the same amount of spiritual power, the stones could only fly slowly, unable to perform maneuvers.

The properties of this material should be the same as thermal conductivity and electrical conductivity. "

Chai Cuiqiao asked curiously, "Conductivity?"

"Conductivity is a measure of the ability of a substance to transmit electric current.

You can simply understand that in rainy weather, Ray prefers to chop metal rather than stone. "

Li Ang said casually: "According to whether a substance has electrical conductivity, substances can be divided into conductors, semiconductors and insulators.

On the aura level,

Pure gold and thousand-year-old mahogany are excellent conductors of aura.

The special armor made by the Zhenfu Division, which can isolate the aura, is the insulator of the aura.

Between the aura conductor and the insulator, such as jade, alloy, and fine steel, are the semiconductors of aura. "

The similar concept was discovered by the academy three hundred years ago, and dozens of hundreds of spirit-gathering formations were developed.

These spirit-gathering arrays are made of different materials arranged according to certain rules, which can speed up the flow of spiritual energy in the space,

In order to speed up the efficiency of practice below the Candle Heaven Realm.

However, because the sources of many materials are gradually decreasing, or the quality is declining, the efficiency of transmitting spiritual energy is constantly decreasing, and the utilization rate of the gathering spirit array is also decreasing.

"The uninitiated monks before the Qi Sensing Realm can slightly speed up the flow of spiritual energy in the body by holding exotic materials, but the increase is almost negligible."

Li Ang said: "However, the broken sword hexagram in my head is quite sensitive.

Even a slight change in the flow speed of the spiritual energy can be transformed into a clear pain sensation.

The more painful it is, the faster the aura flows.

The faster the aura flows, the higher the aura conduction efficiency of the material.

Therefore, it only needs to continue testing to record the specific aura conduction efficiency of each material.

And what I am doing now is to find out the most suitable wire wire just like looking for the material of an electric lamp. "

Li Ang raised the corners of his mouth a little proudly, seeing that Chai Cuiqiao was still worried, he smiled and patted her palm lightly, "It's okay, I know it well, I won't hurt myself.

Although it is not clear what is the essence of Xuan Youxuan's spiritual vein, but the reason should be the same.

If the spiritual vein in my head is naturally broken and cannot undertake the function of transmitting spiritual energy, then I can just connect an external one myself.

Find the most suitable material, connect the broken spiritual veins on both sides, and reconstruct a complete circuit. "

As the time for the final exam was approaching, Li Ang's action efficiency was full. Apart from eating and sleeping, he was testing and looking for a suitable aura conductor, and made countless samples for this purpose.

————

"My thinking is correct."

In the study, Li Ang was alone, looking through the items on the table.

Today is the last day before the final exam, Chai Cuiqiao was afraid of affecting Li Ang, so she moved to Ji Linglang's mansion in Huaidefang, giving Li Ang space to think and experiment alone.

After a period of exploration and exploration, Li Ang based on the location of the craniotomy sword in the frontal lobe area and below the superior sagittal sinus,

Using aura conductors, semiconductors,

Antennas, hats, headbands, headbands, hairpins and even glasses that can be worn on the head have been made.

These accessories made of conductors and semiconductors, when worn on the head, can indeed play a part of the aura conduction function and relieve the stinging pain in the head.

"Currently tested, the conductor with the highest aura transmission efficiency is pure gold."

Li Ang picked up a gold wire that was twisted into a ring shape, and murmured, "However, even pure gold can't transmit spiritual energy perfectly and eliminate the stinging pain in the head."

If you think of the efficiency of aura conduction as electrical conductivity,

Then fine gold is already the best conductor that Li Ang can find so far.

If this still doesn't work, there are only two last options left.

"One, implant the aura conductor directly into the brain."

Li Ang said silently, "The location of the broken spirit vein is the frontal lobe under the skull.

The head bones and skin itself will act as a hindrance, so the effect of the headgear is not as good as expected.

Maybe the fine gold wire is implanted directly under the skull to form a circuit—for safety reasons, it is best to wrap the fine gold wire with an insulating layer.

But the problem is that there are no conditions for craniotomy now. "

Not to mention whether Li Ang is the only neurosurgeon in the world,

Even himself, without hemostasis, disinfection, and anesthesia, he would not perform craniotomy on others.

That's basically indistinguishable from murder.

"And the second method is to find a superconductor that is more efficient in transmitting aura than pure gold."

Li Ang muttered to himself, and stood up from his seat, "If you give me enough time and materials, there may be hope to find it."

Time is running out, there are only eight hours left before tomorrow's final exam in the academy.

"Can I only wear this golden ring to take the exam?"

Li Ang sighed softly, packed the things on the table, put them in the box and locked them,

Putting the golden ring into the medicine box, he sighed and prepared to go out to relax.

As soon as he left the house, he heard a knock on the courtyard door.

"Who is it?"

"Is Li Ang at home? I'm a doctor of mathematics from the academy."

Ph.D. in arithmetic?

Li Ang raised his eyebrows in a little surprise, and stepped forward to open the courtyard door.

Standing outside the door was a pudgy middle-aged man, followed by three young scholars.

"Are you Leon?"

Chao Wenyuan untied the Xuegong jade plaque with the inscription on it from his waist, and said, "I am Chao Wenyuan, a doctor of mathematics in Xuegong, and I was also the one who judged your papers during the first test that day."

"This junior has seen Dr. Chao."

Li Ang arched his hands, feeling a little strange in his heart. What's the matter with the doctor of mathematics from Xuegong coming to see him at this time?

It's impossible to reveal the content of tomorrow's exam, right?

"I just said it directly. I came this time to reveal the content of tomorrow's exam."

Chao Wenyuan said seriously: "Tomorrow, the final exam in the academy will inevitably test the talent of spiritual veins, and candidates are required to use their own spiritual power to solve problems.

So I hope, you will voluntarily quit. "

"Um?"

Li Ang was slightly taken aback, but he heard Chao Wenyuan continue to say: "I have read the hexagrams Xi Yangyu judged, and there is indeed no problem.

There is no way to explain all the hexagrams of skull breaking and swords in history.

Forcibly introducing spiritual energy into the body, at least the brain will be damaged and become stupid and clumsy. In severe cases, the seven orifices bleed and the skull fractures.

You are extremely gifted in arithmetic,

Although the academy stipulates that those with unqualified spiritual talent cannot enter the school, but I have already argued for you in front of the head of the mountain and Jijiu,

I won a place for you as a day student. "

Li Ang asked in surprise, "Study?"

"That's right, your name is not on the student status, but you can use your badge to enter and leave classrooms and attend classes, but you can't live in the school palace, and you can't leave places other than the teaching building."

Chao Wenyuan said seriously: "Historically, the academy rarely accepts day students.

Your talent in mathematics is excellent, it is a pity that you cannot enter the academy because of your incomplete spiritual veins. "

Li Ang was silent for a moment, then cupped his hands again very sincerely, "The student thanked Dr. Chao, but the student still wants to try it tomorrow."

Chao Wenyuan frowned slightly, and the young student next to him couldn't help but frowned and said, "Why are you so stubborn. Do you know that the teacher went to the head of the mountain to make troubles several times because of your affairs."

"alright."

Chao Wenyuan interrupted the disciple's words and stared at Li Ang seriously, "Have you thought about it?

Apart from these restrictions, day students learn no differently from ordinary students.

It's just a piece of school status missing. "

Li Ang still bowed his hands sincerely, without saying anything.

He knew the efforts Chao Wenyuan had put in. The academy was the best academy in the world, and even the descendants of princes and nobles had to follow the rules and enroll according to their own abilities.

A quota for day students, I don't know how much disturbance it will cause and how many people will oppose it.

But... that paper student status is really too important.

Without the status of a genuine school disciple, Li Ang's plans to create inventions, promote modern scientific methodology, and even implement real surgical operations will encounter a lot of obstacles.

It is even more impossible to realize what he promised, to let people have enough food and clothing, to provide for the old, to educate the young, to rely on the poor, to help the difficult, and to heal the sick.

Only by being admitted to the academy in a legitimate manner can people's mouths be blocked and Li Ang's plan can be better implemented.

"All right."

Chao Wenyuan sighed lightly, not too surprised, and laughed at himself: "I think it's true, at your age, you can have such a mathematical attainment.

Nature is a stickler.

but"

Chao Wenyuan suddenly looked down, and said in a deep voice: "If tomorrow's exam really doesn't go well, it's best to withdraw——I will apply to the head of the mountain for the quota of day students and reserve it for you."

"The junior thanked Dr. Chao."

Li Ang sincerely thanked Chao Wenyuan, watched the latter flick his sleeves smartly, and turned away with his disciples.

"What a good teacher."

Li Ang said with sincere emotion that Chao Wenyuan, like Pu Liuxuan, has a real temperament of teaching and educating people.

Advocating rationality, emphasizing practicality, and respecting knowledge, the Academy is such a place.

'I will pass the exam, as a student. '

Li Ang muttered a sentence in his heart, closed the courtyard door, and walked towards the south.

The sunset is just right, the sunset is gorgeous,

Feeling the evening breeze in Chang'an, listening to the sounds of life in the city, Li Ang took a slow walk, gradually clearing away the distracting thoughts accumulated in his mind.

Just walked out of a secluded alley, but heard a "boom" coming from the front.

A heavy carriage was parked at the end of the alley,

The cloth of the car window was lifted, revealing Jiao Cheng's pale face and the crossbow he held in his hand, pointing at Li Ang.

"Little Doctor Li,"

Jiao Cheng said hoarsely, as if he was holding back the pain, "Please get in the car."

py is pushing the book!

"I really don't want to be a disaster"
