Yang Shan made an infusion set with a self-made method, and after infusing the beans, the state of the beans obviously improved, which had to make the old lady stunned and praised again and again.

The old lady doctor still had many questions to ask Yang Shan, and he said: "King, can you tell the old minister how this blood vessel, which enters the human body, spreads to the human body?" ”

Yang Shirt said: "The blood flow of the human body is through the blood vessels, and the blood vessels of the human body are divided into arteries and veins!" ”

"Arteries and veins, this old minister can understand, and he can directly inject liquid into the blood vessels, isn't this very bold?" The old lady was puzzled, he said, "Actually, the old minister has heard that someone has tried to inject decoction into the human body, what the person thought at the time was that people drink medicine for the human blood absorption, but the absorption is too slow, so he directly used a knife to pull apart the meat, exposing the blood vessels and breaking the hole!" ”

Yang Shirt said: "So bold? This is the courage to dedicate oneself to the spirit of innovation! And then? ”

The old lady said: "Later, he endured the pain and forcibly poured the decoction into the blood vessels, but he died immediately, not because of excessive blood loss, but because of the injection of other things into the blood vessels, and he died seriously!" Therefore, people in the medical profession generally believe that only blood can flow in the blood vessels, and nothing other than anything else must not enter the blood vessels! But today, the king's actions have broken the truth, and the old minister thinks that this is a feat! ”

Yang Shirt and the old lady doctor talked to each other about some medical things, in fact, Yang Shirt can only be said to know a little about medicine, but these skins, in the old lady's opinion, are really beneficial.

The two of them had a long talk about the infusion of beans.

Yang Shirt pulled out the needle, wrapped the cotton cloth, and he whispered: "Let the beans sleep well!" ”

The old lady doctor felt that he had learned a lot from Yang Shan, and before he said goodbye, he said, "Wang, I think you can be the old man's teacher!" Can you let the old minister call the king, teacher! ”

Teacher, in ancient times, this was very respected, and it was also the kind that was heartfelt.

Yang Shirt could understand the mood of the old Chinese medicine doctor from the old doctor's eyes and solemnity, he nodded and said: "Imperial doctor, in fact, we call it learning from each other, you call me teacher, and I have learned a lot of new things from you, so I also want to call you teacher, teacher!" Bow down to your disciples! As he spoke, Yang Shi hugged his fist to the old lady doctor and bowed.

The old lady doctor was deeply touched, this time, he did not compliment Yang Shan's status as the king, but bowed to Yang Yi in a quiet mood.

After the old lady left, Yang Shan asked Xiao Lele to take good care of the beans, and he went out with Yana, before going out, Yang Shan took out the bag of things from under the bed, and he said to Xiao Lele: "You must not mention my sack to any outsiders, remember!" ”

Xiao Lele said tightly: "Don't worry, don't worry, Xiao Lele must be tight-lipped." ”

In the end, Yang Shan and Yana left together.

At night, Yang Yi and Yana took advantage of the night to quietly go to the vicinity of Guan Youtou's residence.

The two of them hid behind a wall, and Yana whispered with some worry: "Brother, you say, will Guanyoutou give us the key obediently?" Will he give us fake keys? ”

Yang Shirt said: "I think, Guanyoutou will not give it to us so easily, he can also see that the person we are looking for does not want him to know who it is, and there are so many keys, we want to find one of the keys from the hundreds, it must be like looking for a needle in a haystack!" ”

Yana said: "Brother, do you mean that Guanyoutou will give us the key, but will use a fake key?" ”

Yang Shan shook his head and said: "That's not it, Guanyou loves his baby like his life, and he doesn't know if we have the ability to quickly find the key, so he doesn't dare to use the fake one, in case we can quickly find the key, then, he used the fake one, doesn't it anger us, we are angry, and hide or abolish his treasure permanently, that is equivalent to his life for him, so he will use the real one!" ”

Yana was a little puzzled and said, "But he's going to just let us change the key?" ”

Yang Shirt glanced inside, the patrol soldiers had already patrolled to the back, Yang Shirt said, "Let's go, Yana, in a while, we are going to fight!" You have to be ready for a fight! ”

"Fighting? Brother, are the two of us going to fight with Guanyoutou? Yana asked.

Yang Shirt had already begun to turn into the courtyard, Yana had no choice but to stop asking, and climbed in with Yang Shirt and went to the roof.

Today was different from usual, Guan Youtou did not call people to come by playing cards, he sat alone in the house, or walked around boredly, obviously upset, he must be worried about today's exchange.

Yang Yi whispered to Yana: "You hide here, remember, let us escape and open a way!" ”

"Open a road? Brother, what do you mean by that? "Yana is getting more and more blind.

Yang Shirt said: "In a while, you will know!" Before Yana could react, Yang Yi had already slipped down from the roof and entered the Guanyou Touya through the window.

When Guan Youtou saw the man in black, he was stunned at first, and then when he saw the man in black with a sack of things behind his back, he knew what was going on, he smiled kindly, clasped his fists with both hands, and said: "This big brother, you can be regarded as coming, the most uncomfortable thing in life is to wait, I am a torment!" ”

Yang Shirt still spoke in a false voice, and he said, "Don't talk nonsense between the two of us, what do I want?" ”

Guan Youtou smiled and said: "Things are easy to say, easy to say!" As he spoke, he walked to the cabinet, opened the lock with the key on his body, opened the cabinet, and a large set of keys were placed in it, he took it out of it, shook it, closed the door of the cabinet, and said, "Big brother, it's all here!" ”

Yang Yi stretched out his hand and said, "Throw the key over!" ”

Guan Youtou still had a smiling face, and said: "Big brother, you are also a smart person, you are so anxious to ask for the key, I am even more anxious to ask for the baby that belongs to me, if I tell you, give me the baby first, and then I will give you the key, you will definitely not want to, it is better to put the baby in your hand at your feet, I will put the key in my hand, put it at my feet, let's go to each other at the same time, this is the fairest, how about it?" ”

Yang Shan laughed and said, "I didn't expect you to be very thoughtful, do this, of course, that's good, then do what you say!" ”

Yang Shirt gently put the sack behind him on the ground, and Guan Youtou put the key at his feet, when Yang Shirt was ready to start, Guan Youtou was still worried, he said: "Wait a minute! ”
