As Liu Yu was stunned, these people also looked towards the stairs.

Achang's eyes widened. Others didn't understand. Achang knew best. Master trained these imperial doctors not to deal with errands, but to be sincere. It was really eye-opening to meet such a guy.

Boss Xue held his arm and stood at the entrance of the stairs, as if you were going down to try it.

Zhou Heng smiled slightly and walked to everyone. The people quickly saluted.

"The lower official (student) has met the judge of the Zhou Yuan."

Zhou Heng waved his hand and glanced at Liu Yu who was embarrassed.

"If you have any medical doubts, please ask me and I will answer it. If you just find a reason not to study in Beishan, you can go now and come here freely. Your Majesty just said that you were asked to teach you all medical skills, but did not say how much you learned. I would not do anything that a cow would force his head to press without drinking water."

These people looked at Liu Yu in an instant. Liu Yu pursed his lips, shook his sleeves, and walked back.

"The officials did not intend to contradict each other, but felt that this knowledge and research on corpses are useless and medical skills. Doing these here is just a waste of time."

Zhou Heng said oh, and reached out and took off the cloak on his body.

Liu Yu took a step back, with a hint of vigilance and panic on his face, thinking that Zhou Heng was going to take action.

Zhou Heng just threw the cloak to Boss Xue. Wang Xianqian, who was beside Sun Maocai, had already handed Zhou Heng a quarantine suit. Zhou Heng reached out to change it, put on a hat, mask and gloves.

The gloves they use now are fish skin gloves made by Achang. The seams are bonded with a special fish glue. They are very strong and durable and do not leak. Zhou Heng praised Achang for this time.

Zhou Heng crossed his hands and clasped the gap between his gloves and his fingers.

Then he lowered his head and glanced at the corpse on the middle platform. It was the corpse of a man. It was now broken and the corpse spots had been dead for several days.

He glanced at Sun Maocai and others who were hanging their heads, and they looked like quails one by one. Then Zhou Heng said:

"If you are confused, you need to solve your doubts. If you want to hear it, you can come over. Let's talk about the horse stake in front of you today."

When everyone heard this, they were intrigued and got closer.

Liu Yu hesitated for a moment and walked over. If he left directly, he really had no face. Since Zhou Heng wanted to say it, although he expressed doubts, he seemed to know a little.

Seeing that everyone was gathering, he reached out to light up the horse lantern above his head, held up a magnifying glass, and looked carefully at the head and neck of the body.

Just when he saw the edge of the collarbone, Zhou Heng stopped and stretched out his hand to the side.

"Give me a charcoal."

Sun Maocai quickly handed over the charcoal pen, Zhou Heng took it and drew two circles at both ends of the collarbone of the body, and then stood up.

"Where did you find the corpse?"

Sun Maocai was stunned and said hesitantly:

"It's just the mass grave outside the city. After searching for a few days, some unclaimed bodies were left there. This one looked the most complete, so I picked it up. It was picked up for us."

Zhou Heng gave him a blank look. He was the leader here and he had to save face. Zhou Heng did not have any attacks.

But this guy is really stupid. It's so easy to get into trouble. Why leave a handle for others?

"If you need it next time, you can tell me that I will go to Lord Liu to seek death row prisoners. It's too easy for you to lose the population."

Sun Maocai suddenly realized and nodded quickly.

"The student is stupid."

Zhou Heng pointed to the small sarcoma in front of the body and said:

"This is what you call horse tying stakes, right?"

Liu Yu nodded, "Yes."

"Have there ever been an illustration of embryonic development here?"

Sun Maocai shook his head, "Never before."

Zhou Heng nodded, "Okay, I'll draw a few pictures after that. This horse stake looks like a small sarcoma. In fact, many people have cartilage in this sarcoma. Of course, some people do not have a prominent sarcoma, but may also be a small pit. Looking here, there is a pair of holes in the clavicle process."

Everyone came over, and Liu Yu naturally stretched his head and looked at it. Sure enough, there were two small holes above the protruding point of the collarbone on his neck.

"What does this mean?"

Liu Yu asked subconsciously, and he regretted it even though he asked himself, but neither everyone nor Zhou Heng was confused about whether he asked a question. Zhou Heng pointed to the horse stake in front of his ear and said:

"This person is a very typical abnormal development of the gill arch. In detail, during embryonic development, six pairs of columnar arch bulges appear on both sides of the head of the embryonic body, called gill arches.

When the first and second gill arch develops abnormally, a sarcoma may form in front of the ear. In severe cases, it will form a narrow blind tube or dot-like depression of the skin, extending deep into the body, and communicate with the tympanum, which is an auric fistula. The holes above the ear often flow into white and thick odor or swelling.

The third and fourth pairs of gill arches develop abnormally, which will become cervical sinus, and their residual epithelium may cause cysts or gill fistulas. If the cyst is connected to the outside, gill fistula is formed, and its opening can be located anywhere on the front edge of the sternocleidomastoid muscle of the neck, and it is a gill fistula."

Liu Yu listened carefully. He had already believed 50% of these remarks, but how could Zhou Heng know these things this time?

"How to determine how the embryo in a woman's womb grows, how to judge? We can't take a caesarean section and take a child for inspection. Of course, it's what Zhou Yuan said."

Although it is not nice, it talks about substantive issues. How to prove this?

Zhou Heng smiled and found a round-headed probe on the operating table and threw it to Liu Yu.

"Come on, come here to check, just look in through this small hole to see if there is depth and whether there is a cyst cavity inside. Be gentle on your hand and we will cut it open and verify it later."

Liu Yu also became stubborn and reached out to take the probe, leaned down slightly, and inserted the probe into the small hole on the left.

This probe is actually an extended silver needle, with a blunt and round head and a long foot of an adult man. Unexpectedly, after inserting the small hole, he went in instantly.

Such discovery made Liu Yu stunned and looked up at Zhou Heng in surprise.

"Continue, move lighter."

Liu Yu nodded, and gently used force on his hand. The probe slid in half, and then he couldn't push it.

Zhou Hengyi raised his hand, "I feel the resistance, right? Hold the probe now and don't move it. I will cut this place open. Let's see if there is a cavity of cysts below."

As he said that, Zhou Heng quickly cut the epidermis with a scalpel. After all, he is not a living person, so he doesn’t have to care about the size of the incision. Now it is the key to see clearly, so he directly has a T-shaped incision to lift the skin on both sides.

Just this step, Sun Maocai pointed below and said:

“There is a tube here.”

Sure enough, a long and narrow tube was connected under the hole.

Liu Yu's hand shook, and as the shaking was shaking, the tube also swung. You should know that there is no difference between dead people and a pile of meat, but it is still quite terrifying to see a part move.

Everyone inhaled in an instant, but they just endured and did not retreat. After all, I had never seen such a problem before, and they all wanted to know why.

Zhou Heng separated the surrounding tissue for a while, and then a fusiform capsule hidden under the muscle appeared in front of him. Zhou Heng cut off the surrounding tissue, took out the capsule and tube directly, and placed it on a tray.

Zhou Heng made this judgment just by looking at the horse-tie stake on the deceased's ear and two small holes on his neck. In an instant, the eyes of these people looking at Zhou Heng became even hotter.

Liu Yu had no previous strength at this moment. The probe was inserted into the tube and placed it in the tray with the shuttle bag. He looked straight at Zhou Heng.

"I just want to know how the Zhou Yuan judging? Could it be that your ancestors of the Zhou family have all taken a caesarean section for observation, otherwise how should this be explained?"

Zhou Heng looked at Liu Yu. He thought that this person was just a little persistent, but now he didn't think that he was persistent. He was doubting his medical skills and background. These questions really couldn't be answered.

Could it be that this was learned from a medical university and I came from a world of advanced civilizations than here?

"To be honest, I can't answer your question. I can't even remember my grandfather's name. The memories in my mind, except for medical skills, are all scattered fragments.

I don't know if it was due to head injury or soul-leaving disease, so I can't give an answer. I don't know how I knew it, but facts are better than words. When I checked the corpse, I looked at you and there was a small hole on the upper end of your auricle.
