Heavenly Dao Formula

The three of them stood there blankly, with only one thought left in their minds, what happened just now?

The explosion just now sounded earth-shattering, but not many things were destroyed at the scene, even the weird shelf around Xia Fan seemed intact.

Except for that courtyard wall.

Ning Wanjun took a deep breath and strode towards the entrance of the cave.

"Your Highness, please be careful!" Qiuyue chased after her, blocking herself behind the princess, her eyes fixed on the still smoking copper frame.

Ning Wanjun walked to the wall, bent down to observe for a while, and confirmed his opinion - something penetrated the wall at a very high speed and disappeared outside the villa. The size of the hole is regular, and there are obvious cracks around it, which doesn't seem to be caused by a magic spell. She reached out to explore and found that there was still residual heat inside.

Although this wall is made of red bricks, it is not as hard as a stone wall, but its thickness is about ten fingers. The shock technique!

Although the thunder is strong, it is difficult to destroy the entity, which is also the commonality of the shock technique.

Has Xia Fan's research reached this point?

"Your Highness, are you alright?"

"The subordinate just heard a strange noise coming from the courtyard, and came here to escort him!"

Guards had already approached the gate of the other courtyard, obviously the huge roar just now had aroused their vigilance.

"There's nothing going on here, you stay outside the courtyard and don't let idlers approach!" Ning Wanjun said decisively.

"Obey!"

Then she looked at Xia Fan impatiently, "Can you explain this technique to me?"

"It's just an ordinary streamer technique." The latter spread his hands.

"Shock technique streamer? Isn't that triggering lightning in the palm?"

"Indeed, but when the current is large enough, it can trigger some magical phenomena, such as the generation of strong electromagnetic force-of course, this does not mean that it does not exist when it is small, but it is difficult to attract people's attention."

Ning Wanjun was silent for a while, "...can you speak more simply and understandably?"

Xia Fan was also stuck - after all, he was speaking in the simplest terms. "You can understand that electricity and force can be transformed into each other under certain conditions. The streamer technique seems to just trigger lightning, but through this guide rail, it can be turned into a huge thrust."

This is also the principle of the rail gun.

In fact, Xia Fan himself did not expect the first test to be so smooth - after all, the equipment is really simple and the purity of the copper rods is also worrying. Even the magnets laid under the track are used to guide the electric field and provide additional magnetic force He spent half a day picking all the stones from the blacksmith shop. At the beginning, it was expected that as long as the projectile was pushed against the wall, it would be considered a successful attempt, but it turned out that the copper cone acting as the shell not only hit the wall, but also shot directly through it.

This is really unbelievable.

When Xia Fan cast the streamer technique, he already realized that the technique had undergone subtle changes.

For example, the condensed qi at this time is no longer lively and rough, but thick and stable, like a rolling torrent.

"The most important thing in alchemy is thinking about it."

"Even if it is a spell of the same attribute as myself, different people will have great differences in casting it - it depends on proficiency, understanding ability and personal perception."

The shock technique streamer may have engraved a unique "mark" on his hands.

Ning Wanjun had another thought in his mind.

If this thing can be put on the battlefield, it will definitely be a great weapon in the army!

Compared with iron cannons, a few copper frames are much lighter. And this thing does not need flammable materials such as saltpeter and carbon powder from the beginning to the end, and it will not kill itself in turn.

But none of the above is critical.

The key is that it is too fast, so fast that people are caught off guard!

She asked herself that she could avoid bows and crossbows when she was at full strength, but she definitely couldn't dodge this thing—even capturing its firing line with the naked eye was a difficult thing to do.

When the two armies confront each other, the general will often stand at the front of the team in order to observe the situation and take the lead in the charge. What would happen if the shock technique was used suddenly at this time?

She could see the next scene almost without thinking: the general died before the battle, the enemy retreated timidly, and the own side took advantage of the situation to cover up the kill, how could it be invincible?

"Can I use this technique?" Ning Wanjun's tone became hot.

"Your Highness, your heart is separated..." Qiuyue reminded in a low voice, it was the first time she saw the princess so excited.

Even when she led the army for the first time and won a big victory, she had never been so excited.

It's like a child seeing his favorite toy.

"There is no separation between Li and Zhen. Those who belong to Zhen often turn to practice Li. I don't think this is a problem."

"But you don't even know how many Lijutsu."

"..." The princess was dumb for a moment, her expression was solemn, as if she was engaged in a huge inner struggle, and she patted Xia Fan's shoulder after a long time, "I will start learning the shock technique from today, if there is something I don't understand, I hope you A lot of pointers."

Li Ze put his hand on the other shoulder, and the twinkle in his eyes showed his thoughts fully.

She also wants to learn.

The problem is... the fox demon belongs to Kan, right? Xia Fan slandered in his heart, you are not only in the second position, but also in the opposite position.

But he found that he couldn't refuse the fox demon wagging its tail.

"Okay, I'll teach you some time in the future." Xia Fan said helplessly, "However, this technique is immature, and there are still many problems to be improved."

"Immature?" Ning Wanjun asked in surprise, this is called immaturity, so what will it look like when it is mature? We must know that when the Ministry of Industry meets the requirements of the army, it will make do with less and not give more. "You can't expect it to be as convenient as ordinary alchemy, right?"

"Compared to a certain junior high school student, it's really far behind." Xia Fan sighed—the railgun's routine problems, this test prototype almost didn't miss any. For example, the cannonball and the rail cannot fit tightly, causing the arc to strike, and the high temperature generated by the arc will ablate the rail; another example is that the energy required for its launch is so great that he feels that the energy in his body is exhausted just once. Seven or eight.

Of course, the most terrible thing is that the discharge terminal must be grounded. If he only relies on his body to complete the current circulation and uses his arms as guide rails, then when the improved streamer technique pours into his body, he will instantly become a coke.

This means that as long as Xia Fan wants to use this trick as a trump card in the future, he has to carry a heavy metal frame on his back and ensure that it is well grounded, otherwise it will be tantamount to suicide.

In this way, no matter how strong this technique is, it will not be forceful at all. This is the most distressing thing for him.

People... are still restricted by this body.

The more he studies alchemy, the more Xia Fan feels this way.

It's a pity that no one can understand this regret except himself.

"By the way, why did your Highness come to find me?"

Xia Fan didn't feel that the other party was idle and happened to wander over to him.

Ning Wanjun nodded, "I just want to tell you that I have already recruited all the people you need to make salt."
