"Yes, test the medicine. When the medicine was first made, it could not be given directly to customers because of its unknown medicinal properties. At this time, someone had to find someone to test the medicine." The old man replied.

"However, medicine is for sick people. How can people who are not sick try the medicine? Could it be...?" Mu Xiyun couldn't believe his inference.

"Yes, you are right." The old man's voice became more and more desolate in the cold night. "Of course, the person who tries the medicine must be sick. If you have the same symptoms as the buyer, you can prescribe the right medicine. The pharmacist has a way to make the medicine person also get sick. Watch the effect of the medicine." Speaking of which, the old man sighed: "Actually, getting sick is good, but what's even scarier is testing poison."

"Test poison?"

"Eat the poison first, then take the antidote. If the antidote doesn't work well or doesn't work fast enough, it will try again and again until a fast and good antidote is made. I remember that the master once showed off in front of people that there were Once for a certain poison, it took almost half a year and more than 70 trials to make a perfect antidote."

More than 70 times in half a year, that is, you have to take the poison once every two or three days, wait until the poison develops, and then swallow the antidote of unknown effect. Refining is not timely and loses life. Mu Xiyun shuddered.

"No one knows how he survived, only that after five years of being a medicine practitioner, he finally made it out and became the master's first disciple.

Maybe because of the miserable childhood, the senior brother always gave people the feeling that he didn't care about anything. When the master gave us the task of eliminating demons, he always rushed to the front alone, and he didn't care when he was bloodied every time he fought. The juniors always say that the seniors are good, and they work hard for everyone, but I always feel that he doesn't really care about his own life. Looking back now, I realize that maybe death is more comfortable for him than life. At that time, the senior brother gave people the feeling that he always lost a bit of enthusiasm as a human being. Until a certain time..."

"Sometime what?" A voice suddenly came from behind, and the two turned their heads to see that Qin Le also came out with his clothes on. The little fat man had already slept for a while, and in a daze, he realized that Mu Xiyun was not there, and immediately woke up. Given that the two previous incidents happened when he was sound asleep, Qin Le immediately got up and found it.

Mu Xiyuan waved to him, and the two sat together on the steps of the patio, continuing to listen to the old man's story.

"That year, my brother was fifteen years old, and he went out with the master, as if he was going somewhere in the east. After he came back, although his behavior was the same as usual, I felt that he had changed. Other brothers and sisters I don't seem to notice it, probably because I was only eleven or twelve years old at the time, so I was very dependent on the big brother, and I always stick to his side when I have something to do."

In the eyes of the twelve-year-old boy, the senior brother who came back from the east, when he looked at him, occasionally showed a kind of tenderness in his eyes. When he did something wrong and was punished by the master, he would come to accompany him and be punished; When he is sick and uncomfortable, he will come to take care of him. What I saw the most was the senior brother sitting alone on the roof, watching the sunset and the moon without saying a word. The gentle eyes seemed to penetrate thousands of mountains and rivers, and landed on a place that attracted him and made him always smile.

"Two years later, the master planned to go to the East again. During that time, there seemed to be a flame in the eyes of the senior brother. I have never seen him look forward to a thing so much. I remember one day, he happily said to him. I said that when he comes back with the master to the Central Plains, he will bring me a lot of delicious and fun things."

"What about later?" Qin Le got excited, saw the old man pause for a while, and hurriedly urged.

"Alas!" The old man sighed, "Just a few days before departure, an enemy of the master suddenly came to the door. The master's son was only eight years old at the time and was kidnapped by the enemy. When he was released the next day, he was planted on his body. Seven or eight kinds of Gu worms are dying."

"Gu worm?" Qin Le cried out in surprise, feeling goosebumps all over his body. However, Mu Xiyun suddenly thought of Lin Xuewu from Hongye City.

"Yeah, my master is not good at poison, so he had to send the younger brother to an uncle overnight. He and the elder brother sent people away together, but came back alone."

Mu Xiyuan suddenly had an ominous premonition, and he asked tentatively, "Where's your senior brother?"

"Eldest brother, was left at the uncle's house to test poison."

The author has something to say:

Senior Brother: I was probably sent by Master for the phone bill.

Chapter 52 Guren

"Testing the poison again? Isn't your senior brother no longer a medicine person?" Mu Xiyuan stood up abruptly, Qin Le pulled him slightly in surprise, Mu Xiyuan knew that he lost his temper, and coughed twice in embarrassment. sat down again.

The old village chief glanced at him and said, "It's no wonder you are angry, our brothers are also very angry with the senior brother. But the master thinks that the senior brother can be a medicine man for five years and not die, it is really a gift. It's better to leave him to try the poison."

"Then can your brother agree?" Qin Le asked.

"I don't know what the master promised him, but the senior brother finally agreed. Sigh! What is the friendship between master and apprentice, how can it be compared to the family relationship between father and son."

"Then what happened to your senior brother?" Qin Le asked.

"At that time, I was very reluctant to go to my senior brother. I often went to inquire about news. I heard that the solution of the gu was not smooth. The seven or eight kinds of gu poison were mixed together. It was very difficult to suppress one and arouse the other. Later, the uncle made a desperate attempt, Use the medicine to temporarily control the younger brother and plan to refine the Gu King. Do you know how to refine the Gu King?"

I haven't seen it before, but I read it in the small story book, Qin Le hesitantly replied: "Put all the worms in a jar and let them kill each other..."

The old man didn't know what to think, a tremor flashed in his eyes, and nodded: "That's right, but that time uncle was going to train, it was Gu Ren."

"What is... a Gu Ren?" Mu Xiyun's voice trembled.

"It is to lock people and Gu insects together in the mountains to kill each other. In the end, the person who can survive is the Gu person."
