Li Baotian hurriedly begged for mercy: "Okay, okay, then you continue to blow, oh no, continue to say, 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 gymnasium." ”

Li Baotian glanced at his students, and said angrily: "Get out of the way, can this be used as a perfusion material for liver casting?" ”

"Yes!"

"Yes?"

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

Although Li Baotian was full of questions, when he saw the student looking so serious, he didn't open his mouth and decided to take a look.

I saw Chen Qi take a ping pong ball, slap it a few times, and then began to cut it into small pieces with scissors and threw them into a glass filled with nitric acid.

In the process of waiting for the pieces of the table tennis ball to melt, Chen Qi quickly used 1000ml of distilled water and two sticks of heparin sodium, 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 ball in the nitric acid was almost melted and became a little viscous.

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

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

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

And if he looked closely, he found that although Chen Qi had a variety of materials and looked very irregular, the whole technique seemed to be very regular, not like messing around.

It's just that from the perspective of his knowledge, he still can't understand why he doesn't use the materials prepared by the school and uses table tennis?

If you really want to ask Chen Qi, Chen Qi doesn't know, he only knows that Professor Wu is doing this, so he will draw a gourd in the same way.

It's best if you succeed, if you don't succeed, uh, then get another corpse from Pingshui and continue the experiment, anyway, the school leaders are also mentally prepared for this.

By this time, the clock had already shown that it was 12 o'clock in the middle of the night.

In the past, Li Baotian and Chen Qi would finish the day's specimen making work, go back to wash and rest, after all, they had to go to school and work the next day.

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

Suddenly, the empty dissecting small building seemed to have a very light footsteps walking by.

The sound of the soles of the shoes rubbing against the ground was very soft, looming, from far and near, and then abruptly stopped.

Chen Qi's ears were very sharp, and he immediately raised his head, because he had been working under the lamp just now, and he was still a little uncomfortable when he looked at the dim place in the distance, and he didn't see anything.

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

Li Baotian raised his head and looked left and right: "No, I said, why are you suddenly suspicious?" What, scared? Ha ha. ”

Fear is not afraid, but the atmosphere in the dissection room is a bit eerie, no, there is a fresh corpse on the dissecting table that has been dissected and the internal organs have been dug out.

Coupled with the footsteps in the middle of the night, it made people get pimples in their muscles.

Since he was reborn, he's gone from an atheist to a theist, and he kind of believes in that thing.

Chen Qi was not at ease again, looked around, and after making sure that there was nothing abnormal, he continued to bury himself in making his own specimens.

After a while, Chen Qi felt that a hand suddenly pressed on his back, and at the same time, Teacher Li Baotian also felt that he suddenly had an extra hand on his back.

Thinking of the middle of the night, there were a large number of dead people around, which instantly made the hair of both of them stand on end.

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

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

"Don't argue, don't talk."

Well? This voice is 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, both of them breathed a sigh of relief, but then they became nervous again.

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

Chen Qi's first thought at this time was: "This guard school won't be really haunted, right?" ”

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

In the special era of the Wei School, I heard that there were many teachers and students who committed suicide, and the Wei School was an old house, which made people think about it very scary.

Chen Qi's mouth moved, he didn't dare to make a sound, and asked Master Wang in a low voice, "What happened?" ”

Master Wang is a veteran veteran, and he has also been on the battlefield to kill devils, you must know that his salary is higher than that of the principal, so there is a fine light in the old man's eyes.

"I was just patrolling the campus when I noticed a figure sneaking into your dissection building, did you notice it?"

Hiss~~~~

Chen Qi and Teacher Li gasped, and the footsteps just now ......

So Chen Qi told Master Wang about what happened just now.

Master Wang snorted lightly,

"It's sneaky in the middle of the night, it's either a monster or an enemy agent, Mr. Li, you go and talk about it right away, and the teacher on duty will call you. Chen Qi, you and I will carefully search this small building, whether it is a person 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 fast as he could.

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

The two took off their shoes again and crept down the stairs to search the second floor.

There was no light on the second floor, but the moon was very bright tonight, and the two of them didn't dare to light the light, so they went forward in the dark and checked one room after another.

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

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

"Wang, Master Wang, back, back......"

Master Wang was much bolder, and when he heard that there was a situation behind him, he raised his eyebrows, and then quietly luckily, turned around suddenly, and knocked the mop back.

"Go!"
