As Liu Yu was stunned, these people also looked in the direction of the stairs.

Ah Chang's eyes widened, others don't understand, Ah Chang knows best, Shizun's cultivation of these imperial doctors is not to deal with errands, but to be sincere, it is really an eye-opener to meet such a guy.

Boss Xue hugged his arms and stood at the top of the stairs, as if you were going down to try it.

Zhou Heng smiled slightly, walked in front of everyone, and these people hurriedly saluted.

"Xiaguan (student) has seen the judgment of the Zhou court."

Zhou Heng waved his hand and glanced at Liu Yu in embarrassment.

"If you have doubts in medicine, you can ask me, I will answer, if you just find a reason and don't want to study in Beishan, you can go now, come and go freely here, Your Majesty just said let me teach you medical skills, and did not say how much you have learned, I will not do the matter of the cow not drinking water and pressing the head."

These people all looked at Liu Yu instantly, Liu Yu pursed his lips, flicked his sleeves, and walked back.

"Xia Guan didn't mean to contradict it, he just felt that this knowledge and the study of corpses were useless to medical skills, and it was just a waste of time to do this here."

Zhou Heng sighed, stretched out his hand and took off the big on his body.

Liu Yuchao took a step back, with a hint of vigilance and panic on his face, thinking that Zhou Heng was going to make a move.

And Zhou Heng just threw the big gown to Boss Xue, Wang Xianqian on Sun Maocai's side had already handed Zhou Heng an isolation gown, 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 Ah Chang, and the seams are bonded with a special fish glue, which is very strong and durable, and does not leak.

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

Only then did he glance at the corpse on the middle table, which was the body of a man, who had been disemboweled, and the corpse had been dead for several days.

Glancing at Sun Maocai and the others who hung their heads, they looked like quails one by one, and Zhou Heng said:

"If you don't understand, you have to solve your doubts, if you want to hear it, you can come over, let's talk about this ear tethered horse stake today."

As soon as they heard this, everyone was interested and came closer.

That Liu Yu hesitated for a moment, but still walked over, if he left directly, he really had no face, since Zhou Heng wanted to talk about it, although he expressed doubts, he also seemed to know a thing or two.

Seeing that everyone had gathered, he stretched out his hand to brighten the horse lamp above his head, held a magnifying glass, and carefully looked at the head and neck of the corpse.

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

"Give me charcoal."

Sun Maocai hurriedly handed over the charcoal pencil, and Zhou Heng took it and drew two circles on both ends of the clavicle of the corpse, and then stood up.

"Where did you find the corpse?"

Sun Maocai was stunned for a moment, and said in a hesitant manner:

"That's it...... It's a mass grave outside the city, we searched for a few days, and some unclaimed bodies were left there, and this one looked like the most complete beard and tail so I picked it up, right...... We picked it up. ”

Zhou Heng gave him a blank look, he is the leader here, he must save face for him, and Zhou Heng did not have a seizure.

But this product is really lacking in heart, how easy it is to get into trouble, why bother to leave a handle for others.

"Next time, if you need to, you can tell me that I will go to Lord Liu to ask for death row prisoners, it is too easy for you to be truthful."

Sun Maocai suddenly nodded quickly.

"The students are stupid."

Zhou Heng pointed to the small sarcoma in front of the corpse's ear and said:

"This is what you call a hitching stake, right?"

Liu Yu nodded, "Yes." ”

"Is there ever an illustrated book of embryonic development here?"

Sun Maocai shook his head, "Never." ”

Zhou Heng nodded, "Okay, I'll draw a few after that." This tethered stake looks like a small sarcoma, but in fact, many people have cartilage in this sarcoma, of course, some people are not protruding sarcoma, and it may be a small pit, and then look here, there is a pair of holes in the clavicle process. ”

Everyone came over, and that Liu Yu naturally looked at it, and sure enough, there were two small holes above the protrusion of the collarbone in the neck.

"What does that mean?"

Liu Yu subconsciously asked, and he regretted it a little after asking, but everyone and Zhou Heng didn't bother whether he asked or not, Zhou Heng pointed to the horse stake in front of his ear and said:

"This person is very typical of gill arch dysplasia, in detail, during embryonic development, six pairs of columnar arch-shaped bulges appear on either side of the head of the embryonic body, called the branchial arch.

When the first and second branchial arches are abnormally developed, sarcoma can be formed in front of the ear, and in severe cases, a narrow blind tube or punctate depression of the skin will be formed, which will extend to the deep part and communicate with the tympanic cavity, that is, the preauricular fistula, and the hole above the ear often smells white and foul, or swells.

The third and fourth pairs of gill arches are abnormally developed, which can become cervical sinuses, and cysts or gill fistulas may occur in the residual epithelium. If the cyst communicates with the outside, a gill fistula is formed, and its opening can be located anywhere on the anterior border of the sternocleidomastoid muscle in the neck, which is a gill fistula. ”

Liu Yu listened carefully, he had already believed fifty percent of his remarks, but how could Zhou Heng know about these things?

"How is it judged how the embryo in a woman's womb grows? We can't take the child by caesarean section, let's check it, naturally it is what the Zhou court judges. ”

Although the words are not good, they talk about the substantive issues, how to prove this.

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

"Come, you come and check, just poke into this small hole to see if there is depth, whether there is a cyst cavity inside, light your hand, we will cut it open and verify it later."

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

This probe is actually an extended version of the silver needle, but the head is blunt and round, the length of an adult man's hand, but I didn't expect it to enter in an instant after inserting the small hole.

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

"Go on, move gently."

Liu Yu nodded, with a slight force in his hand, the probe slid into half of it, and then it couldn't be pushed.

Zhou Hengyi raised his hand, "Feel the resistance, right, you hold the probe now and don't move, I'll cut this place, let's see if there is a cyst cavity below." ”

Saying that, Zhou Heng quickly cut the epidermis with a scalpel, after all, he is not a living person, he doesn't care about the size of the incision, and now seeing clearly is the key, so he directly made a T-shaped incision to open the skin on both sides.

Just this step, Sun Maocai pointed below and said:

"There's a tube here."

Sure enough, a long, narrow tube was attached to the bottom of the hole.

Liu Yu's hand shook, and with this shaking, the tube also swayed, you must know that there is no difference between a dead person and a pile of meat, but it is still quite terrifying to see a part move.

In an instant, everyone gasped, but they didn't retreat, after all, they had never seen such a question before, and they all wanted to know why.

Zhou Heng separated the surrounding tissues, and then a fusiform sac hidden under the muscle appeared in front of him, Zhou Heng cut off the surrounding tissues, directly took out the sac and tube, and put them on the tray.

Zhou Heng just looked at the tethered stake on the deceased's ears and the two small holes in his neck to make this judgment, and in an instant, the eyes of these people looking at Zhou Heng were even hotter.

Liu Yu had lost his previous strength at the moment, and the probe was inserted into the tube, and it was placed in the tray with the fusiform sac, and he looked directly at Zhou Heng.

"I just want to know, how did the Zhou court judge know? Could it be that the ancestors of your Zhou family all took their children by caesarean section for observation, otherwise how can this be explained? ”

Zhou Heng looked at Liu Yu, he thought that this person was just a little persistent, but now he sees that this is not obsession, this is a doubt about his medical skills and background, these questions really can't be answered.

Could it be that I learned from a medical university, and I come from a world with an advanced civilization than here?

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

I don't know if it's because of a head injury, or if it's because of Soul Disorder, so I can't give an answer, I don't know how I know, but facts speak louder than words, and when I looked at the corpse, I looked at you, and there was a small hole in the top of each of your ears.

I wonder if you can squeeze out white pus there, whether it will swell and stink in summer or spring and autumn, I don't need to explain, you know better than anyone else, yes and no? ”
