Looking at the towering skyscraper in front of him, Su Fei couldn't help but be full of pride.

Worthy of the headquarters of the Dan League, the scale of the skyscraper is much more majestic than the branch of Dongjiang Province, and the gate is crowded with people, and everyone has their own alchemist badge pinned to their chest.

There are as many ninth-grade and eighth-grade alchemists here, and seventh-grade alchemists can also be seen at will, even Su Fei, a sixth-grade alchemist like Su Fei's master Fu Kang, saw three or four at once.

"It's really worthy of Danmeng, I've really seen a lot. Feeling the lingering charm of a sixth-grade alchemist who had just passed by, Su Fei couldn't help but sigh.

Mingshu stayed by Su Fei's side and didn't say anything. She wore a loose casual sweatshirt and jeans today, plus a peaked cap, and she looked like a girl still in high school.

Su Fei wanted to follow the flow of people into the hall, but was stopped by a security guard at the door: "This gentleman, please show your alchemist badge." ”

"Oh, forgot, sorry. Su Fei conjured up an alchemist badge and hung it on his chest as if he were juggling, and said with a smile: "Is this okay?"

The security guard nodded and smiled slightly: "It's okay, please show your ID to this young lady as well." ”

Mingshu didn't mean to take out the documents, and the security guard was a little puzzled, and a few laughs sounded behind him: "Master Su, Mingshu!

Wang Rui led a young man who was about the same age as Su Fei approached with a smile and said to the security guard: "These two are my friends, I will guarantee them." ”

"Yes, Master Wang. ”

Wang Rui was one of the four seven-rank alchemists who had been to Gong's house last time to inspect the Broken Nightmare Pill, and he seemed to be very popular at the Danmeng headquarters, and this security guard quickly let Ming Shu and Su Fei go through the relevant registration procedures.

Sitting in the elevator, seeing that there was no one around, the smile on Wang Rui's face narrowed slightly: "Mr. Su, the Dragon Master-Ren asked me to cooperate with you in the research of this project, and you can use my third-level alchemy room at will, and you can also tell me directly if you need anything." ”

"However, the project is urgent, and you still need to step up. Every minute earlier in the development of the product, it is possible to save the life of one more fighter. ”

"I know that. Su Fei nodded and glanced back at Ming Shu: "Isn't Ming Shu's identity not easy for other alchemists in the Dan League to know?"

Wang Rui nodded: "The Hidden Dragon Department is special, and there are only some people in the Dan League who are related to the Hidden Dragon, so the people who are outside the Hidden Dragon will not reveal their identities." This research on the Nightmare Pill has also been carried out secretly with me, and no one else knows about the existence of the Nightmare Pill for the time being, so as not to cause panic. ”

The elevator went all the way up, and after stepping out of the elevator and passing through several criss-crossing corridors, Su Fei arrived at the tertiary laboratory assigned to Wang Rui by the headquarters of the Danmeng.

This third-level alchemy room is not bad, although it is not as good as the one built by Su Fei with heavy money, but it is also seventy percent new, and the equipment is also very well maintained.

After changing into isolation gowns and protective clothing, Su Fei handed a prescription that had already been written to Wang Rui: "Give me three copies of the materials for the Breaking Pill first, and I'll try my hand." Then prepare the herbs on the Danfang. ”

"You already have an idea?!" Wang Rui said in surprise.

Su Fei under the tempered glass mask smiled slightly: "There are a few, you have to try it to know." ”

Generally, a seventh-rank alchemist will not allow anyone else to enter his alchemy room after the alchemy begins, except for his closest assistants, during alchemy.

But this time the research and development of the pill is very important, and Wang Rui accepted Long Yi's instructions to follow Su Fei closely every step of the way, and not miss any steps, so he applied to Su Fei to let him stay in the alchemy room.

Su Fei pouted noncommittally at this instruction, "I don't care, but I think Master Wang, you can just watch from the side, and you don't need to take notes, just go back and tell you the key points." ”

Wang Rui's mind was full of question marks: Is this disliked?! It's not enough for a seven-grade alchemist to get started?

But after Su Fei started to really alchemy, Wang Rui, who had questions, swallowed all the doubts into his stomach.

Goo-Du –

Wang Rui couldn't help but swallow his saliva and muttered, "This is ...... Flowers are scattered?"

Ouyang Xun is the youngest deputy director of the R&D department of the Danmeng headquarters, and he is the man of the year in the Danmeng headquarters.

But this is Ouyang Xun's unique Dan Dao stunt, how many people want to copy it but can't, how did Su Fei learn it!

In Wang Rui's stunned, Su Fei had already completed the refining of the three pairs of Breaking Pills, and then began to research and develop new drugs on the basis of Breaking Pills.

Mingshu was sitting in the isolation room of the alchemy room, watching the surveillance images in the alchemy room, and she was also dumbfounded.

Although Ming Shu didn't understand alchemy, she could see the appearance of other people when they were alchemizing, and the kind of aura that Su Fei exuded from her body when she was refining pills Ming Shu could clearly feel it, making her suddenly feel that what she was in front of her was not Su Fei, but a Dan Dao bull who had been immersed in the Dan Dao for many years.

"I really didn't expect Mr. Su's alchemy skills to be so exquisite. Mingshu couldn't help but sigh: "No wonder Brother Long wants me to try my best to have a good relationship with Mr. Su, such a person should naturally enter our Hidden Dragon to serve the country, otherwise it would be a pity." ”

At the end of the day, Su Fei didn't move at all in the third-level alchemy room.

Alchemy, analysis, summary......

Re-alchemy, re-analysis, re-summary......

After practicing, Wang Rui was already showing fatigue, but Su Fei was getting more and more energetic.

Because of the speed limit of other people's alchemy, they could only refine a few furnaces of pills in a day, but under the staggered hands of the flowers, Su Fei's efficiency was dozens of times higher than theirs!

The seven plans that Su Fei came up with overnight yesterday were all tried in one day today, but unfortunately, none of them could achieve the effect that Su Fei expected.

There is no doubt that the Nightmare Pill can resist the infection of the primordial Nightmare, and what Su Fei has to do now is to use some method to prolong the effect of the Pill as long as possible, so that the person who takes it can be protected while the effect of the medicine remains.

However, after the improvement of the Danfang, although it can prolong the effective protection time of the Nightmare Pill after swallowing, the effect of the extension is not satisfactory. Su Fei tried, and the best solution was to extend the effect of the medicine for twelve hours, after which it would completely lose its protective effect.

It's nothing if you can swallow it every twelve hours, but if you take it continuously for a short period of time, it will make the human body resistant, so that the effect after each swallow will be greatly reduced on the basis of the previous one, and at most three consecutive pills will completely lose its protection.

After a day of observation, Su Fei's status in Wang Rui's heart has risen to a considerable height. Su Fei's life information Wang Rui had already obtained it from Long Yi, a Dan Dao genius who could self-teach and realize the blossoming flowers, this alone was enough to make him respect Su Fei.

"Master Su, why don't we rest for a while? It's eight o'clock now. Seeing that Su Fei finished pondering, Wang Rui interjected at the right time, full of respect.

"It's only eight o'clock, no, what are you talking about eight o'clock?" A look of astonishment flashed on Su Fei's face.

Wang Rui knew too well the expression on Su Fei's face at the moment, almost every alchemist who fell into madness would be like this, Wang Rui smiled and said, "It's already eight o'clock in the evening, let's go here today, let's go to dinner." ”

"Well, okay then. ”

Although it is also called a canteen, the canteen of the Dan League is quite luxurious, and the dishes in it are also rich to the extreme, after all, this is the headquarters of the Dan League, and the alchemist is the richest group of people in the world, how could the Dan League not do his best.

Even when he was eating, Su Fei was still thinking hard about the improvement plan of this Breaking Pill pill, Wang Rui came to bring three cups of water, and put two of them in front of Su Fei and Mingshu with a smile: "Come, drink some water." ”

"Thank you, Master Wang. Mingshu smiled gently, revealing a mouthful of delicate snow teeth, bright and moving.

Su Fei was still thinking about things, and when he heard this, he subconsciously turned his eyes to Wang Rui, only to see Wang Rui take out a small white bottle from the inner pocket of his clothes, pour out a few capsules from it and throw them into his mouth.

"What, you're sick?" asked Su Fei.

Wang Rui took a sip of the water cup and swallowed the pill with his head up, and said with a smile: "I have a little high blood pressure, and I haven't taken medicine during the day, just remembered." ”

"Blood pressure medication. ”

Su Fei said casually, but when he said that he was completely stunned, he snapped and said: "I have thought of a solution, haha!

The entire cafeteria heard Su Fei's laughter, and the alchemists all looked at this side with some curiosity, and Su Fei's eyes burst out with a certain excitement: "Master Wang, do you know a professor who specializes in pharmacy? I want to learn from him!"

"Pharmacy?Western medicine?" Wang Rui didn't react for a while, but still nodded: "I know, Gao Shan is a doctor of pharmacy specializing in gene medicine." ”

"Takasugi, the one we had dinner with last time?"

"yes. ”

"Then let's go find him!"

…………

In Danmeng's standard apartment, Gao Shan looked at Su Fei with some surprise: "Master Su, do you mean that you want me to apply the production principles of sustained-release tablets and control tablets to the Nightmare Breaking Pill?"

"That's right, I want to use this to prolong the protection time of the Nightmare Pill. Su Fei nodded and said excitedly: "Professor Gao, let's see if this idea can be realized?"

"In principle, there is nothing wrong with that. ”

"So what are you waiting for, let's go!"

Before Gao Shan could react, he was directly pulled into the drug production workshop of the Danmeng headquarters by Su Fei overnight.

Sustained-release tablets are basically divided into three types: skeleton sustained-release, film-released sustained-release, and microcapsule sustained-release.

The sustained release of the skeleton is made of insoluble materials such as polyethylene, polymethacrylate, silicone rubber and other materials that will not dissolve, and the active ingredients are placed inside the bone. After taking it, gastric juice or intestinal juice enters the skeleton, and the active ingredients of the drug are slowly dissolved to achieve slow release.

Film sustained release is to make the drug into small pills, and then dissolve the films at different rates on the outer bread, and then pack them in the capsule shell according to the proportion. In the digestive tract, these membranes, which dissolve at different rates, gradually dissolve and then slowly release the active ingredients within them. Fenpidex cold medicine is of this type.

The sustained release of microcapsules is similar to the second type, but the coating material is generally semi-permeable. In the digestive tract, water seeps into the microcapsule to form a saturated solution, and then uses the concentration difference to diffuse into the digestive juice outside the microcapsule to be absorbed by the body.

After discussing with Takasugi, Su Fei planned to try all three.

Takasugi also became more and more excited under the influence of Su Fei's atmosphere, and the two worked together, and soon the prototype production test in the workshop was in full swing. Originally, Takasugi planned to call his assistant to help, but Su Fei was very quick to get started, and Takasugi understood everything as soon as he said it, which also made the cooperation between the two more and more tacit.

Wang Rui's current feeling can almost be described as the two heavens of ice and fire.

On the one hand, he is old, and at this time it is already past his usual time to sleep, and his body has begun to be tired. But on the other hand, Su Fei's idea made him energetic, this feeling was like knowing how to play games in the second half of the night, and he felt that the whole person seemed to be able to fly.

Su Fei didn't pay attention to it so much, and when the sample test was about to be tested, Du Mingshu immediately shouted: "Call Professor Wu and Professor Yang and ask them to get ready for animal experiments!"

"The two old professors should have gone to bed by this time, let's do the animal experiments ourselves. Takasugi pushed down his glasses, and the light in his eyes became more and more amazing: "I have a feeling that this time there is a good chance of success!"

The production workshop they use is inside the headquarters of Danmeng, and there is also a corresponding animal experiment base here.

Mingshu had already called in advance to ask the technicians of the experimental animal group here to prepare, and when Su Fei and Gao Shan arrived here, the experiment was immediately launched.
