Li Baotian quickly beg for mercy and said, "Okay, okay, then you can continue to brag, oh no, continue to talk, how to choose this material?"

Chen Qi took a net bag from the corner, and there were white table tennis balls in it, "Teacher, look, this is the material I took from the sports room."

Li Baotian glanced at his student and said angrily: "Get out, can this be used as a filling material for liver casting?"

"able!"

"able?"

Chen Qi didn't talk nonsense, and took the ingredients he had prepared long ago, a pile of ping-pong balls and a cup of nitric acid.

Although Li Baotian was full of problems, he stopped talking when he saw the student looking so serious and decided to take a look.

Chen Qi took a ping-pong ball, slapped it a few times, and then began to cut it into small pieces with scissors, throw it into a glass cup containing nitric acid.

While waiting for the ping-pong ball fragments to melt, Chen Qi quickly used 1,000 ml of distilled water and added two pieces of heparin sodium to inject it from the liver artery, bleed from the veins, and repeatedly rinsed the blood vessels in the liver until the fluid outflow became clear.

At this time, the ping-pong balls in the nitric acid were almost melted and became a little sticky.

Chen Qi put his liver in a basin filled with water, then took out a syringe, pulled out a filler made of nitric acid ping-pong balls, and injected it into the liver artery.

During the perfusion process, Chen Qi kept rubbing the liver with his hands to allow the filler to flow into the blood vessels in the liver.

Li Baotian wanted to speak out several times, but when he saw the students who were working hard, he stopped again.

And if you look closely, he found that although Chen Qi's materials are diverse and seem to be very irregular, the whole technique seems to be very regular, not like a mess.

But from his knowledge point of view, he still can't understand why he doesn't use table tennis if the materials prepared by the school are used?

If you really want to ask Chen Qi, Chen Qi doesn’t know either. He only knows that Professor Wu is doing this, so just do it as usual.

It’s best to succeed, but if you don’t, uh, then get a body from Pingshui and continue the experiment. Anyway, the school leaders are mentally prepared.

At this time, the clock had already been displayed at 12 o'clock in the middle of the night.

In the past, Li Baotian and Chen Qi would finish the day's specimen production work, go back and wash it and have a rest. After all, people who have to go to school and work the next day.

But today, because they were experimenting with the new method of liver casting, the two of them were head-to-head and observing the liver soaked in water very carefully.

Suddenly, the empty anatomy building seemed to have very light footsteps passing by.

The sound of the sole of the shoe rubbing against the ground was very light, looming, from far to near, and then abruptly.

Chen Qi had a very good ears and immediately raised his head. Because he had been working under the desk lamp just now, he suddenly looked at the dim place in the distance and was still a little uncomfortable and saw nothing.

"Teacher Li, have you just heard the footsteps?"

Li Baotian raised his head and looked around and said, "No, I said, why are you suddenly suspicious? Why, are you scared? Haha."

It is not afraid of being afraid, but the atmosphere in the anatomy room is a bit gloomy. So, there is a fresh corpse on the anatomy table with a belly cut open and the internal organs dug out.

Coupled with the sound of footsteps in the middle of the night, it made people feel goose bumps.

Since he was reborn, he has changed from an atheist to a theist, and he has somewhat believed in that thing.

Chen Qi was worried again, so he looked around and confirmed that there was nothing abnormal, and continued to focus on making his own specimens.

After a while, Chen Qi felt a hand suddenly pressing on his back. At the same time, Teacher Li Baotian also felt that there was a hand on his back.

Thinking of the midnight at night, there were a lot of dead people around him, and their hair stood up in an instant.

Master and apprentice look at me, I look at you, the calmness I just now no longer exists, and my face has changed.

Just as Chen Qi was about to shout "Ghost~~~", a sound suddenly sounded in his ears.

"Don't make noise, don't talk."

Well? The sound is so familiar. Isn’t this Mr. Wang, the doorman and security guard?

Li Baotian and Chen Qi then slowly turned around and saw Master Wang's old face. Both of them breathed a sigh of relief, but then became nervous again.

Because Master Wang looked obviously alert, he felt something bad had happened.

Chen Qi's first thought at this time was: "Isn't this medical school really haunted, right?"

It seems that every school has legends of ghosts, such as big-footed ghosts, long-tongued ghosts, hanged ghosts, mother-son ghosts, etc., and they all change after death by former seniors or teachers.

In the special era of the past, I heard that there were many teachers and students who committed suicide. In addition, the health school was an old house, which made people terrified to think about it carefully.

Chen Qi's mouth moved, and did not dare to make a sound. He whispered to Master Wang, "What happened?"

Master Wang is a veteran who has retired from the army, and he has also been on the battlefield to kill the Japanese. You should know that his salary is higher than that of the principal, so there is a glimmer in the old man's eyes.

"When I was patrolling the campus, I found a figure rushing into your anatomy building. Have you noticed it?"

Hiss ~~~~

Chen Qi and Teacher Li took a breath of air conditioning, the footsteps just now...

So Chen Qi told Master Wang what happened just now.

Master Wang snorted with a light nose,

"Sneaking in the middle of the night, either a monster or an enemy specialist. Teacher Li, you will tell me that the teacher on duty will call you. Chen Qi, you can search this small building carefully with me. It is a human or a ghost, so you must not let it run away."

Chen Qi swallowed.

Teacher Li quietly left the anatomy classroom and ran to the dormitory area as fast as possible.

Chen Qi picked up a broom next to him, and Master Wang picked up a mop. The two of them searched several anatomical rooms on the first floor, but found nothing.

The two took off their shoes again, tiptoed along the stairs, and searched on the second floor.

There was no light on the second floor, but the moon was very bright tonight, and the two of them dared not light the lights. They just walked forward in the dark and checked the rooms one by one.

Master Wang was in front and Chen Qi was behind. Suddenly, Chen Qi found a black shadow appeared behind him, floating around constantly.

Chen Qi was so scared that his teeth were about to fight, but he didn't dare to look back or shout. He just quietly hugged Master Wang in front of him, and finally he hung on the old man like a sloth.

"Wang, Master Wang, behind, behind..."

Master Wang became much more courageous. When he heard something behind him, his eyebrows stood up, and then he turned around suddenly and hit the mop back.

"go!"
Chapter completed!
