Sulfonamide antibiotics may be more effective in treating pneumonia, but Yi Zhicheng doesn't have so much time to study compound drugs, not to mention that he is only a doctor, and he only dabbles in the study of these things when learning strange knowledge.

In comparison, the purification of penicillin is much simpler. Yi Zhicheng himself did such an experiment when he was in junior high school.

There are many orange trees planted on the island, and it is not difficult to find a few moldy oranges. Kong Kongyi quickly found five or six and brought them here.

Yi Zhicheng scraped off the mold, poured it into a petri dish, poured in a little nutrient solution, explained it step by step to Kong Kongyi in detail, and took notes: "The production cycle of penicillin is a bit long, I can't give it to you. All of you are injected, and I can only tell you the method, and you must remember the refining process."

"Ah...I...I'll do my best!" Kong Kongyi nodded nervously.

The essence of the healing technique is to provide energy to promote cell division. At this time, the effect on Penicillium is the same. The Penicillium that needs to be cultivated for a week has covered several petri dishes in a few minutes, and it is stronger than ordinary Penicillium. Can be called Super Penicillium.

Yi Zhicheng then poured the Penicillium into the fish oil and stirred thoroughly to form three layers of liquid, fat-soluble substances, insoluble substances and water-soluble substances.

Penicillin is a water-soluble substance, and the bottom liquid is full of penicillin.

Then use carbon powder to absorb impurities, filter with distilled water, dissolve in acidic water, and neutralize in alkaline water to obtain relatively pure penicillin.

The steps seemed simple, and it took the two of them busy for three days on this broken island with nothing before they got a bottle of penicillin.

At the same time, the system prompts:

"Invention of impure penicillin: get 30 good doctor points"

"Impure penicillin? Let's try it on pirates..."

"No! This is the fruit of our hard work, I want to test it myself!" Kong Kongyi held the reagent bottle very resolutely, as if fighting for the custody of the child.

"Well, anyway, as long as you're not dead, I can bring you back to life." Yi Zhicheng took out a syringe, took out the solution and gave Kongkong Yipi a test, and injected it after confirming that there were no adverse reactions.

Injected for three days in a row.

Perhaps the bacteria and viruses in this world have never been sanctioned by drugs, and there is no drug resistance, and the effect of penicillin is very obvious.

On the first day, Kong Kongyi felt his body cool down.

Only then did Yi Zhicheng know that the normal body temperature of mermaids is 35 degrees, and their body temperature seems normal, but they are actually running a fever all the time.

The next day, Kong Kongyi breathed the air on the ground no longer felt hot, but just as fresh.

On the third day, the scales on Kong Kongyi's body began to fall off naturally, revealing her fair skin. Almost all the mermaids began to cry at this scene.

On the fourth day, the fins on the back of Kong Kongyi's neck fell off, revealing her azure blue hair.

Yi Zhicheng didn't have more time to admire her beauty: "Your Majesty, I have developed the medicine, but my homeland is being invaded by Mist, please forgive me for not being able to treat all of you, but the medicine The configuration method has been handed over to Kong Kongyi, please allow us to leave the Broken Sea."

"Well, since the homeland has been invaded, we should go back early. We are ready and can leave here at any time." Queen Aisa did not mean any delay.

What's more, their combat effectiveness is stronger in this scale armor state.

Only Kong Kongyi is slightly unhappy, the scales on her body have not been completely stripped off, she has not yet shown her most beautiful appearance to Master Cheng, and has not yet been able to sing her heart with the most beautiful voice...

The Magic Pill was already prepared under Gu Ming's integration. 125 cannons were installed, and eight of the most accurate cannons were installed on the bow.

400 outstanding sailors were integrated from more than 800 pirates. They all survived the mermaid enslavement for more than ten years, and their bodies are also the strongest. After eating and drinking during this period, they have recovered most of their past fighting power.

In addition to the Magic Maru, there is also the White Shark and three other well-preserved ships serving as the frigate and supply ship of the Magic Maru. The captains are the Captain Jiji and Captain Baba that Yi Zhicheng met at the beginning .

And promised them that as long as this war is over, all pirate freedom will be returned.

Although Yi Zhicheng didn't expect this group of pirates to have any fighting power, the most important thing was their Magic Pill.

Leaving the Mermaid Island, the Magic Pill sailed slowly above the Broken Sea. With the Mermaid Clan as the pilots, the thick bottom of the ship did not need to be afraid of the ubiquitous sharp reefs on the bottom of the sea. Open, there is really no way around it, the mermaid queen can also set off a wave and raise the water level.

The other four first frigates followed closely behind, and soon left the Broken Sea.

At the same time, they also encountered the five warships headed by the Hidden Fog Fleet, which was still guarding overseas.

In the same 5v5, the enemy is even more jealous when meeting each other.

The Fuxing was almost ravaged under its huge body. Thinking of the humiliation in the past, all the crew members were full of fighting spirit.

The Glacier looked at the small broken ship that had escaped from its men, not only sank the pursuing Iron Broken Tooth, and captured the White Shark, it had even turned into a warship of the same size at this moment, sending out a signal to prepare for battle.

Gu Ming picked up the binoculars and made sure that the captain on the opposite side had also spotted them. With a playful face, he personally picked up the bright red flag and raised the flag.

Although Yi Zhicheng couldn't understand what he was talking about, but seeing the cheering and booing of the pirates, he could tell that there was definitely a lot of swearing.

Regardless of the fact that the captain and high-level officers of the Glacier on the opposite side are all from the Snow Tribe, they have practiced ninjutsu in extremely cold places all year round. The entire crew entered a state of combat readiness and seized the upper hand.

Gu Ming also threw down the flag, turned around and looked at the sloppy pirate crew, with an evil smile on his face: "I know what you **** are thinking now, hurry back to the shore, drink! Eat meat! And mother Ladies! Hahahaha, I think so too!"

"However, those cubs who only hide in the fog and play tricks, blocked our way to touch women! They blocked the freedom we had so hard to get!"

"What do you say!!"

"Kill them!"

"Eat their flesh! Drink their blood!"

"Oh! Very good..."

"Everyone returns to their combat positions and prepares to attack!"

"Full sails! Set sail!!"

The clattering black sails lowered, and the speed of the Magic Maru slowly increased. Since it was in the downwind zone, even with full wind, the speed was only thirteen knots, and it was still under the condition of more than thirty wind ninjas blowing the wind. .

There is no way, the Glacier is waiting, and has already occupied the best wind direction. If the Magic Pill tries to go around and compete for the windward area, it is likely to expose its fatal weakness and be crushed by the Glacier's iron horns.

The mermaids offered to dive to the bottom of the ship, but Gu Ming and Yi Zhicheng rejected it at the same time. They have seen the ability of the Glacier to freeze the sea for hundreds of miles. If the mermaid is frozen, there will be no one. I can save them.

In this way, the Magic Maru and the Glacier are like knights charging each other.

One held a 40-meter-long spear, vowing to pierce people through it.

One is carrying a sharp and heavy axe, trying to split the opponent in half!
