The yard is large, but it looks particularly crowded.

The huge yard is filled with long tables, almost filling the space, and it is quite difficult for people to pass by.

The long table was filled with things, various jars, jars, jars, porcelain bottles, bowls, and drawers of all sizes, and the drawers were filled with various medicinal materials.

When he was a few hundred meters away, Du Ao smelled a strong fragrance.

It's the aroma of medicine.

At this moment, I finally understood the reason.

The man in black robe strode forward, Du Ao followed closely behind and looked at him secretly.

The man in black robe is tall and thin, and his whole body is very tightly wrapped. Not only does he not see his age or appearance, but he cannot even see his men or women. Moreover, his body gives people an unknown, repression and hatred, which makes people not want to or dare to get close to him.

The objects placed on the long table seemed to be messy to others, and it was very difficult to find something. But the man in black robe knew it. He took a green porcelain bottle from the many items on the long table and threw it to Du Ao, and said coldly: "Drink it."

Du Ao didn't know what was in the porcelain bottle, so he took it and opened it, and drank the medicine with a faint salty smell. His movements were straightforward and clear, and he did it in one go without hesitation.

Even the man in black robe who treated human life as much as grass showed surprise.

Du Ao's actions are indeed cool, but the consequences are also serious.

In less than three blinks of fingers, a pain from the heart of thousands of arrows came from my stomach. My face and hands immediately turned blue, and even my eyes turned miserably green. This was obviously a poisoning reaction.

What he drank was poisonous, and it seemed to be extremely poisonous!

Du Ao fell to the ground and rolled on the ground without long support.

Just when Du Ao was in pain, the cold voice of the man in black robe came over.

"Describe your reaction after taking the medicine and explain it clearly."

Du Ao wanted to curse his mother in his heart. The wave after wave of pain made him almost collapse, but he still controlled himself with great will and thought about the various changes in his body after taking the medicine.

"At first my stomach feels swelling and pain, then it's like thousands of needles, then my brain becomes numb, then my hands and face itchy, and then my left and right chest cavity is hot..."

Du Ao's face was ferocious, he was very difficult to speak, and his voice was stuttering, but he still said in detail.

The man in black robe had a strange look again.

He was not surprised by Du Ao's patience, but was surprised that Du Ao could accurately express the reactions that appeared in his body while enduring such severe pain. Although there were a few problems with some words, he did not miss it.

From this point of view alone, Du Ao can be called the best drug test target, whether for those who study medicine or poison.

At this moment, the man in black who had been with poison for many years even had the idea of ​​taking Du Ao back to try the medicine. However, this idea was fleeting. She knew that it was impossible for Xue Yiren to value Du Ao.

Retracting his thoughts, he took a porcelain bottle from the table and threw it to Du Ao, who was worse than life and death, and described in detail the poison that Du Ao had taken just now: "This poison is called Baizhu Pill, light green, emits a corrosive odor, with a salty taste, and a very fishy smell. It is mixed with bear's paw meat but it is almost colorless and tasteless. The way to distinguish it is..."

The man in black robe used a cold voice to tell Du Ao, who had just taken the antidote, the characteristics, the properties of the poison, the methods of poisoning, the methods of identification, and the methods of treatment.

Du Ao, who has been through the gates of hell, must remember even if he is dull by nature. What's more, he has the ability to remember everything he sees, so he will never forget it.

The man in black robe did not know that Du Ao had such skills, and made Du Ao eat all kinds of poisoning things. He stopped after Du Ao could completely retell it.

The stop here is just a temporary stop.

All this is just the beginning of Du Ao's suffering.

Du Ao slightly restored his strength, and the man in black robe asked Du Ao to distinguish the next poison.

The method is simple and crude. Take it first and take it. After you feel it thoroughly, you will give it an antidote. Then tell me the characteristics, usage and the method of this medicine. Then use it to let Du Ao take it, detoxify and correct it.

Then continue.

Repeat.

Although Du Ao endured the pain of poisoning again and again, he did not refuse every time he took the poison because he understood Xue Yiren's intention.

There are many ways to kill people in the world, and the most terrifying one is assassination.

The most terrifying one of the assassinations is poisoning.

It is obvious that Xue Yiren is giving people to teach him his skills in this regard.

Only by understanding the poison, understanding the methods of poisoning, understanding the situation of poisoning, understanding the methods of understanding the poisoning, can we prevent and save ourselves.

Du Ao fully understood Xue Yiren's intentions.

Du Ao studied very seriously, very carefully and meticulously, and could even practice repeatedly when there was something he didn't understand.

This surprised the man in black.

Normal people will have a more or less resistant attitude when it comes to taking poison. They don’t know how many times they use people to try poison, but they have never seen someone like Du Ao.

But these are all irrelevant things, so I don't care too much.

One is willing to teach and wants to teach quickly, and the other is willing to learn and wants to learn quickly, so he will naturally cooperate and make progress quickly.

At least twenty or thirty types were identified every day, sometimes even forty or fifty types, but even so, Du Ao studied it for three months before he had almost finished it.

According to the man in black, there are thousands of poisons. Even the Wen family and the Tang sect, which specialize in poisoning, have no way to know all the poisons.

There are thousands of poisons, which can be roughly divided into 133 categories. As long as you have enough experience, you can prescribe the right medicine and kill people to save people.

Du Ao remembered the words of the man in black robe very clearly and dared not forget them. After all, this was a major event that concerns his life.

After spending time together, Du Ao discovered two things.

First, although this man in black robe is indifferent, he is not a person who is difficult to talk to. The first point is not important, the second point is that this man in black robe is actually a woman.

This made Du Ao very excited. Is there another man who doesn’t want to teach his skills a beautiful woman? Even if he can’t learn much, he can still be beautiful and eat.

However, Du Ao did not see the appearance of the man in black, and he didn't even know the name of the man in black. The man in black never mentioned his past, but it could be heard that her voice was full of hatred, as if she lived for hatred in her life.

Du Ao just heard the woman's original voice by chance. She was very crisp and cold, as if she was tall and arrogant, which made people imagine.

Du Ao had no imagination, and even dared not think about it, because this woman's methods were indeed very vicious.

On the 100th day, Du Ao did not test the poison. When he came to the yard, he found a half-person-high bathtub in the yard. The bathtub was filled with water and various medicinal materials.

Although Du Ao is not a doctor, he has made a lot of progress during this period. It can be seen that many of them are precious medicinal herbs, and many of them are poisons!

There are many types of poisons and many ways to get poisoned.

Some poisons do not need to be taken, and the smell can kill people. Some poisons are not poisonous, but they can become poisonous after being mixed and mixed.

There are many types of medicinal materials in the bathtub, many of which are very expensive.

The man in black robe was very simple and direct, and said to Du Ao: "Take off all your clothes and go in!"

Du Ao was stunned for a moment.

It’s not that Du Ao was afraid, but that the person in front of him was a woman, which was a bit unnatural.

The man in black robe seemed to know what Du Ao was thinking and said coldly: "Test the medicine these days, what secrets does your body have to me, why bother with it?"

Old Du Ao blushed and had to admit that although he had not completely dragged it out in front of the man in black, there was indeed no secret.

After thinking it through, I immediately took off my clothes and entered the bathtub.

As soon as he entered, Du Ao felt as if salt had been sprinkled in the wound, and was in great pain, and then his whole body felt like a needle prick.

The pain came so strong that Du Ao was about to faint.

The voice of the man in black robe came: "You can't faint, otherwise you will die."

Du Ao was shocked and immediately controlled himself.

But at this moment, Du Ao looked very ferocious and could not hold on.

The man in black robe looked at Du Ao who was struggling in pain at this time, and suddenly felt emotional in his ruthless eyes. The man in black robe suddenly thought of how he looked like when he was practicing with his father in the past, and at that time she could hardly hold on with Du Ao at this time.

A pair of cold eyes softened, and the sound returned to its originally crisp and indifferent voice.

The man in black asked about the doubt that had been pressed in his heart for a long time and said, "Do you know that I used poison on you these days?"

Du Aoba had no choice but to talk to him so that he would not have to fall into a coma: "Of course I knew, I knew it when I took the medicine for the first time."

The man in black robe said, "Since you know, why don't you hesitate to accept it?"

This is what she is most puzzled.

Du Ao couldn't help but scream in pain, but he still controlled it and said gasping: "Because you were found by my master, he wants me to listen to you and there must be no violation."

The man in black robe sneered, "He wants you not to go against me, just listen to him?"

"yes!"

"Why?"

Du Ao said: ‘I believe him.’

The man in black robe sneered: "A man in the martial arts world should not believe in people. If you believe in people in the martial arts world, you may die."

"I know."

"But you believe him?"

"I only believe him."

The man in black robe was stunned and couldn't help asking, "Why?"

Du Ao screamed in pain and said, "This world is indeed beautiful, but it is more full of ugliness. People are lonely living in such a world, but people should always give a chance to believe in someone in this life. Even if they betray them, they will have no regrets! I will give him this opportunity, and I will not trust anyone again from now on."
