In the class, the teacher is explaining the basic knowledge of Xiuzhen pharmacology, mainly to identify where the animals are in the Heihe Valley (for example, here), which plant minerals are useful or poisonous, which can cure diseases, and so on.

Han Yin found Yao Jia dressed as herself...... In the sleep of the big sleep.

He suddenly felt that there were still a lot of shining points in this girl, for example, Yao Jia couldn't sleep last night, he should be worried that he Han Yin would be killed, right?

In fact, this morning, Han Yin had already found a way to break the game, because the chip had thoroughly analyzed Nie Yun, the white fox, including the reason why the fox demon absorbed the qi of yin and yang.

As early as the moment when he patted Nie Yun on the shoulder for the first time, this stupid female fox demon was in a state of being "hung up and analyzed" by the chip, and it had all been analyzed this morning.

Just like when he analyzed Bai Min.

Fox demons suck the qi of yin and yang, one is cultivation, and this is secondary, because they are not unable to use spiritual power and aura to cultivate.

The second is addiction, which is predominant.

It can improve its cultivation again, and it can make you feel cool, and you can level up while lying down, but if you change it, will you do it?

Han Yin felt that he might not be able to resist this temptation.

Through ingredient comparison, Han Yin has found a substitute for the qi of yin and yang, and the mixing and refining of a variety of herbs can be made!

It should make the fox demon feel "cool" when inhaling yang qi, but it can't improve the cultivation of a thing.

Now there is a problem, the herbs are in the plantation on the edge of Xuanwu Lake, and when class is over, everyone in the class will visit there. Of course, except for the young master Zhao Xinzhu and his follower Douzi, who skipped class again.

But where to go to mix and refine?

After class, the "Eight King Kongs" quietly followed behind Yao Jia, who Han Yin pretended to be, and looked quite imposing. At the back of the line, follow the teacher to the herb garden by Xuanwu Lake.

"By the way, you guys work in pairs, and you'll help me find the four spirit grasses later. ”

Han Yin introduced to the eight people what kind of grass they needed to find.

"This kind of cat spirit grass, a little more. Remember to keep a low profile and give it to me when people aren't looking. ”

There are more people in the herb garden who go to touch the herbs, as long as they are not valuable, the academy generally does not care (the precious herbs are in the inner garden, not open to the public, and Han Yin can't enter). But organized picking needs to be applied, and Han Yin doesn't want to startle the snake.

Potpourri, cat's spirit grass, black withered leaves, and leaves of dragon's beard root, all four herbs are available, well, no problem.

As for the formula ratio, it needs to be very precise, and the proportion of ingredients contained in each batch of medicinal materials is not exactly the same.

Han Yin felt that without the analysis of the chip, it would be difficult for him or others to do it.

The outer garden of Chongming Academy's medicine garden is full of common herbs, no wonder they are not very wary of others stealing herbs, because it is really unnecessary, and the gains outweigh the losses.

Duan Peng casually walked over to Han Yin, lowered his voice and said, "Boss Yao, we have already obtained the herbs, and it is very smooth." ”

The teacher of the pharmacology class explained on the spot in the medicine garden, in fact, this is also some basic knowledge, Han Yin knew it before, but he still waited patiently for the end of the class.

The more critical the moment, the more you can't be impatient.

The procrastinating explanation finally ended, and Duan Peng and the others had been waiting impatiently, like ants on a hot pot, but they had to endure desperately.

As soon as the teacher announced that he would disperse on his own, Han Yin took the "Eight King Kongs" to a Yin Willow Forest by Xuanwu Lake.

"Boss, live up to your mission!"

Han Yin nodded, put away the herbs collected by everyone, patted them on the shoulders in turn, and said, "Don't worry, I will find exercises that are suitable for you in the future, I am sincere, if you are good to me, I will be good to you, and I will not engage in so many false things." ”

Simply buying people's hearts, Han Yin is still very skilled, anyway, it is Yao Jia who will contribute money and efforts in the future, and it is not him Han Yin, why can't you say anything?

"Boss, we will definitely follow you closely in the future, and we will teach whoever you let us teach!"

Duan Peng said on behalf of these expressions of loyalty.

Just when the atmosphere in the "community" was harmonious, and he almost wanted to cut off the head of a chicken and burn yellow paper to become brothers of the opposite sex, Han Yin suddenly felt palpitations, like something sharp against his temples.

That feeling was even more serious than the first time he was targeted by the big snake in the Qiankun glass umbrella, almost the kind that he was so frightened that he didn't dare to move.

"It's not good, spread out!"

Han Yin shouted, still one step too late!

Duan Peng and the others didn't have time to run, their bodies had already flown into the air, and they were slapped by someone!

Most of the people were hit before they could see the appearance of the person who came, and only Duan Peng barely took it.

A few seconds later, there were only eight poor worms on the ground clutching their stomachs.

Han Yin didn't say anything, slapped a stack of hardening talismans on his chest, and ran away! He still hadn't seen what the black shadow looked like.

A sword was hit in the left shoulder, but fortunately, there were enough hardening charms and fierce enough, although the pain made him want to cry his father and call his mother, but there was no blood, the force of the shock made him stumble, and the donkey rolled on the ground many times, looking very embarrassed.

Ma Maipi, what about the assassination at night? How can you assassinate in such an open fire during the day, no, open killing.

Still don't talk about the rules?

At this moment, Han Yin found that the things he had learned before were not useful, a person's strength did not depend on the state of spiritual power, sometimes the strength exceeded too much, and the weak side did not even have a way to see the opponent clearly.

"Hercules!"

Han Yin continued to take out the spirit rune and stick it to his chest, and took the opponent's sword with his right hand!

Mars were shining, Han Yin took three steps back, and only then did he see the appearance of the person who came.

A very tall and thin man, wearing a leather jacket, dressed as a gangster, with red eyes, and Nie Yun had the same virtue when he wanted to absorb the yang energy of a fat man.

A dagger in the left hand, and a dagger in the right hand... Claws.

This guy is most likely a master of the black fox.

Han Yin's right hand was already numb to the point of pain, and the hardening charm could harden the body, but it couldn't be immune to pain.

How much it hurts to be stabbed with a knife, that's how much it hurts there now.

He touched his pocket, there was also a stack of Divine Talismans inside, which could increase his speed of escape to the extreme, and once this guy made a move, Han Yin threw out a stack of Divine Talismans and fled. Probably a few minutes later in death.

At the last moment, the tall and thin young man suddenly froze.

He turned his head sideways with difficulty, and found Dean Yu Hong approaching slowly, looking calm and breezy.

You are finally willing to come!" Han Yin almost cried with joy. It's not easy for my brother to hold on until now.

The killer brother's body began to writhe abnormally, his hands moved to the position of his neck, and his head moved to his feet, as if the picture had become a messed up painting, and then he screamed, and the picture returned to normal, with a black fox lying on the ground, and a pool of blood, which made people's hairs stand on end.

"Killing people in the academy during the day, without my consent, there is no forgiveness for killing!"

Yu Hong walked over and picked up the fox's tail, and then the fox who didn't know whether he was alive or dead turned into ashes, this hand was really amazing.

"Space is misaligned, time accelerates... Awesome. ”

Han Yin still doesn't understand the rules of Yu Hong's fight, and it is obvious that he can't manipulate space and time at will, at least not let the living die of old age.

But sometimes it's a light lift, which may have something to do with the strength of the opponent. For example, when facing Ouyang Jiujian, Yu Hong performed quite hard.

This is a higher-level battle, under such a difference in strength, any conspiracy and tactics become meaningless.

"Thank you for your hard work, the danger is lifted. Your response just now is very exciting. ”

Yu Hong looked at Han Yin and did not hide the appreciation in his eyes at all.

Han Yin shrugged his shoulders and nodded indifferently. The shouts of Duan Peng and others came from behind him.

"Boss, boss, you're alright... bar. ”

These little brothers saw the majestic Yu Hong, all of them were like roosters strangled.

"You all disperse, I still have something to say with Yao Jia. ”

Yu Hong waved his hand, Duan Peng and the others scattered, leaving Han Yin alone.

"Dean, I'd like to borrow the extraction room later. ”

"The forty-third floor of the Dean's Building is my private laboratory, so you can use it. ”

After speaking, Yu Hong threw a key to Han Yin and left without looking back.

"This key has the rules of time and space, you can try to feel it. When you leave the Dean's Building, it will naturally disappear. ”

Yu Hong's words were still echoing in his ears, and Han Yin always felt that the other party seemed to be ordering him something, and when he thought about it, he felt that he was making himself amorous.

He departed a trace of spiritual power to hang on this key, trying to use the chip to analyze what kind of name he was.

When I came to the extraction room, the instruments here were similar to those in the previous textbooks, they were all relatively rudimentary, and there was nothing particularly powerful, but this time Han Yin didn't need it.

The crux of the matter is the formulation. Each time, the approximate proportion is certain, but the details are still different, and if you can't control it accurately, the things you make will have no effect, because the special ingredients in the four herbs will produce some subtle changes.

In the very fragile microenvironment created after mixing, a small amount of new substances will be generated, and finally the cat spirit grass will be added to allow it to absorb that substance, and finally dried in the sun, and the processed cat spirit grass will be ground into powder.

This small amount of new substance, similar to a fragile catalyst, is rare, cannot be preserved, and is generated under sensitive conditions. Among them, the cat spirit grass is not only a medium, but also a carrier carrier.

"The ratio is 1 to 2 to 2 to 3.5, and 20 parts of cat spirit grass are added..."

Han Yin wore a mask and carefully adjusted it, forgetting the passage of time.

By the time a batch was completed, the sun had already set.

"I got one kilogram of powder, which is enough for a spirit fox to suck from birth to death. ”

Breaking the game, after all, you still can't rely entirely on those who fight and kill, and treat the symptoms but not the root cause.

Kill the black fox once, and sooner or later they will make a comeback, which will bring a lot of instability to Han Yin's future.

"The problem still has to be solved. It's not my character to be beaten passively. ”

Walking on the way back, Han Yin thought secretly in his heart.
