Li Baotian quickly begged for mercy: "Okay, okay, then you continue to brag, oh no, continue to talk, how to choose this material?"

Chen Qi took a net bag from the corner, with white table tennis balls inside. "Teacher, look, these are the materials I brought from the gym."

Li Baotian rolled his eyes at his student and said angrily: "Go away, can this be used as a perfusion material for liver molds?"

"Yes!"

"Can?"

Chen Qi didn't waste any time and took the materials he had prepared a long time ago, including a pile of table tennis balls and a cup of nitric acid.

Although Li Baotian's mind was full of questions, when he saw the students looking so serious, he stopped talking and decided to wait and see.

I saw Chen Qi taking a table tennis ball, hitting it a few times, and then started to cut it into small pieces with scissors, and threw it into a glass filled with nitric acid.

While waiting for the table tennis fragments to melt, Chen Qi quickly added two bottles of heparin sodium to 1000 ml of distilled water, injected it from the liver artery, bled from the vein, and repeatedly flushed the intrahepatic blood vessels until the outflow became clear.

At this time, the ping pong balls in the nitric acid have almost melted and become a little sticky.

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

During the perfusion process, Chen Qi kept kneading and pressing the liver body with his hands to facilitate the flow of filler in the intrahepatic blood vessels.

Li Baotian hesitated to speak several times, but when he saw the students who were working seriously, he stopped again.

And if he observed carefully, he found that although Chen Qi had a variety of materials and looked very irregular, his overall technique seemed to be very regular and did not look like he was messing around.

But from his academic point of view, he still can't understand why he uses table tennis instead of using the materials prepared by the school?

If you really have to ask Chen Qi about other things, Chen Qi doesn’t know. He only knows that Professor Wu did it this way, so he can just follow the same example.

Success is the best, but if it doesn't succeed, well, then get another corpse from Pingshui and continue the experiment. Anyway, the school leaders are also mentally prepared for this.

At this time, the clock has already shown 12 o'clock in the middle of the night.

In the past, at this time, Li Baotian and Chen Qi would finish their taxidermy work for the day, go back and wash themselves before resting. After all, they have to go to school and work the next day.

But today, because they were testing a new method of liver molding, the two of them faced each other and observed the liver soaked in water very carefully.

Suddenly, there seemed to be light footsteps walking past the empty anatomy building.

The sound of the soles of the shoes rubbing against the ground was very light, vague, coming from far away, and then suddenly stopped.

Chen Qi's ears were very good and he 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, but saw nothing.

"Teacher Li, did you hear footsteps just now?"

Li Baotian raised his head and looked around: "No, why are you so suspicious all of a sudden? Why are you scared? Haha."

It’s okay to be afraid, but the atmosphere in the autopsy room is a bit eerie to begin with. No, there is a fresh corpse on the autopsy table with its stomach cut open and its internal organs dug out.

Coupled with the sound of footsteps in the middle of the night, it makes people's skin crawl.

Since his rebirth, he has changed from an atheist to a theist, and he somewhat believes in that stuff.

Chen Qi was worried and looked around to make sure there was nothing unusual, then continued to work on his own specimen.

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

Thinking of the pile of dead people around in the middle of the night, their hair instantly stood up.

Master and disciple, you look at me and I look at you. The calmness just now is no longer there, and their expressions have changed.

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

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

Huh? This voice sounds so familiar. Isn’t this Uncle Wang, the doorman and security guard?

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

Because Master Wang obviously looked wary, it felt like something bad had happened.

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

It seems that every school has ghost legends, such as big-footed ghosts, long-tongued ghosts, hanged ghosts, mother-child ghosts, etc., and they are all transformed after the death of former seniors, teachers, etc.

In the special era of the Medical School in the past, I heard that many teachers and students committed suicide. In addition, the Medical School is an old building, which makes people think deeply.

Chen Qi moved his mouth but did not dare to make a sound. He asked Master Wang in a low voice: "What happened?"

Master Wang is a retired veteran who has also been on the battlefield and killed Japanese soldiers. You must know that his salary is higher than that of the principal, so the old man's eyes are shining.

"When I was patrolling the campus just now, I noticed a figure running into your anatomy building. Did you notice it?"

Hiss~~~~

Chen Qi and Teacher Li took a breath of air. The footsteps just now...

So Chen Qi told Master Wang what happened just now.

Master Wang snorted slightly,

"It's sneaky in the middle of the night. It's either a monster or an enemy agent. Teacher Li, go immediately and call the teachers on duty. Chen Qi, please search this small building carefully with me. Whether it's a human or a ghost, we must not let it escape."

”

Chen Qi swallowed.

Teacher Li quietly exited the anatomy classroom and ran to the dormitory area as quickly as possible.

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

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

There were no lights on the second floor, but the moon was very bright tonight, so the two of them didn't dare to light the lights, so they just walked forward in the dark and checked each room.

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

Chen Qi was so frightened that his teeth were chattering, but he didn't dare to look back or scream. He just quietly hugged Master Wang in front of him tightly, and in the end he was almost hanging on the old man like a sloth.

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

Master Wang was much more courageous. When he heard what was going on behind him, he raised his eyebrows. Then he secretly got lucky, turned around suddenly, and knocked the mop back.
