Yun Duruo and Nangong Yi have lost contact with us for almost ten days, and we have been waiting for the results of our search almost sleeplessly, but every time the news comes back, my hopes are dashed little by little.

Time is the most important thing for rescue, if I can't find them in the first three days, I think the chances of Yun Duruo and Nangong Yi surviving will become very slim, not to mention that ten days have passed, I sometimes really don't dare to think about it and even force myself to sleep, I just hope that when I open my eyes, they will stand in front of me safely.

But I couldn't sleep at all, as soon as I closed my eyes and my mind was full of them, I smoked all night and waited distraughtly for tomorrow, telling myself again and again that maybe tomorrow they would be found.

When it was almost dawn, Han Yu and the prince hurriedly pushed the door in, and the essential oils and soaps tested by the forensic department had already yielded results, and animal fat was found in the essential oils.

"Animal fat?" I was stunned, snuffed out the cigarette butt in my hand, took the report, read it grimly, and said in surprise. "Essential oils are generally volatile aromatic substances extracted from plants, how can there be animal fats in them?"

"Could it be that Xu Wanjun added animal fat to the development of glycerin?" Han Yu asked.

I frowned, and my eyes fell on the proportion of animal fat in the test results, from the test results, Xu Wanjun used the essential oil produced by the subsidiary of Hede Medical College to contain a large amount of animal fat, according to the production of essential oil and soap, which requires a lot of animal fat.

I took Han Yu and the prince to leave to find Song Chi, after the case of Hede Medical College was solved, because there were many things involved, and the case was extremely complicated, all the subordinate enterprises were taken over and closed by the military police, and I planned to let Song Chi check the source of animal fat.

Since Xu Wanjun said that we have not been exposed to the secrets of this school at all, perhaps in order to find Yun Duruo and Nangong Yi, we must first uncover the truth that Xu Wanjun has not told us.

When we saw Song Chi, we were all stunned in place, we hadn't seen him for half a month, Song Chi was old, we couldn't believe it, the skin on his face was completely loose and lacklustre.

"How so?" I asked, surprised.

"Don't mention it, it's all those essential oils and soaps, and it became like this after it was stopped, and now it's much better, and it should be able to recover slowly." Song Chi sighed weakly and looked at us anxiously and asked. "Do you have any news from Du Ruo and Nangong Yi?"

"Nope." I shook my head in disappointment, regained my energy and handed the test report to Song Chi. "Help me check the source of the purchase of the company affiliated with Hede Medical College, and I want to find out where such an astonishing amount of animal fat comes from."

Song Chi nodded and asked us to wait for him in the office first, and when I met the butcher at the staircase, he still glared at me with a gloomy face.

"Follow me to the office."

We silently followed the butcher, who walked back and forth in the room several times before stopping in front of me and speaking angrily.

"You can't protect two big living people, what else can you do?"

I haven't listened to the butcher's reprimand for a long time, and I suddenly felt a little kind, and I could see that he was also worried about the disappearance of Yun Duruo and Nangong Yi, and I buried my head and didn't know what to say.

"It's not the time for you to play dead, how is it going, it's been ten days! Ten days and still no news at all! The butcher stared at me sternly.

"There are a total of four ways to enter and exit Hede Medical College, and they didn't know where to go when we went to capture Xu Wanjun and others, but according to the school guards, Xu Wanjun and the others did not leave from any of them, so I believe they should still be in Hede Medical College now." I replied in a low voice.

"Now that you know that this group of crazy people has not left Hede Medical College, so many military and police have been used to search for ten days in the palm-sized place, and they have not found anyone?" The butcher asked angrily.

"I've searched for all the places I should be looking for, and I've done many carpet searches for Hede Medical College, but ...... But there was no trace of Xu Wanjun and others. I replied with my head bowed sincerely.

The butcher just pointed at my nose and was about to scold, Song Chi knocked on the door and came in, the butcher was angry, and he couldn't even say anything after pointing a few times.

"I have investigated the supply of raw materials to the enterprises under the Hede Medical College, and I remember that I told you last time that when I traced the income and expenditure of the Hede Medical College, I found that there was an imbalance, and the proportion of funds invested in the purchase of raw materials was abnormal, and there was no animal fat purchase at all." Song Chi interjected, probably to help me stop being scolded by the butcher.

"No animal fat purchase history?" Han Yu said in surprise. "How did the test results show that there are a lot of animal fats in the essential oils and soaps?"

"Xu Wanjun can instruct An Rongyue to add the glycerin that is forbidden to be developed to essential oils and soaps, and what's the difficulty in secretly adding animal fat." The prince said thoughtfully.

"The question is, why are animal fats added to essential oils? What does it do? I frowned and couldn't figure it out. If animal fat is added, why is it not recorded in the expenditure on raw material supply? ”

"It seems that Xu Wanjun and others don't want anyone to know that animal fats are added to essential oils and soaps." Song Chi replied.

"To learn to see the essence through the phenomenon, you should think more about what the intention of Xu Wanjun and this group of madmen is to conceal the addition of animal fat." The butcher said solemnly with his hands behind his back.

In fact, I have been thinking about this question, even if adding animal fat will play a role in lubricating the skin, this is a very normal thing, but why did Xu Wanjun and others secretly join it?

I took out a cigarette and just put it in the corner of my mouth, looked up and saw the skin on Song Chi's face that had lost its elasticity and luster after sagging, and suddenly I was stunned and slowly raised my hand to touch his face, Song Chi looked at me at a loss, and just wanted to ask me what I was doing, but I interrupted him and asked him not to move.

"You've used those oils and soaps, and what are the effects of them?"

"It feels very good, at least the skin is very delicate and elastic before it is stopped, and the essential oil looks like water when applied to the body, but it dissolves into the skin instantly, and there is a very smooth feel." Song Chi replied.

My hand touched Song Chi's face, and suddenly the cigarette at the corner of his mouth fell to the ground, and I watched in shock as the corner of Song Chi's mouth squirmed a few times.

"I know why Xu Wanjun and the others are hiding the raw material procurement of animal fat."

"Why?" The others asked in unison.

"Because it's not animal fat at all that is added to essential oils and soaps!" My hand was withdrawn from Song Chi's face.

"That'...... What's that joining? Han Yu asked in surprise.

"Corpse oil!"

Song Chi looked at me dumbfounded, his mouth was wide open and speechless for a long time, the butcher also turned to look at me in surprise, Han Yu and the prince were also surprised when they heard me say these two words, animal fat will only make the skin smooth, but it is impossible to be absorbed by the human epidermis, only human fat will adapt to the epidermis, I think of the glycerin developed by Xu Wanjun, presumably Xu Wanjun also found that corpse oil is the best carrier in the process of research and development, because it can easily penetrate under the epidermis.

The expensive essential oils that Song Chi had been applying to his body were actually just corpse oil quenched from corpse fat!

That's why there's no such thing in the procurement of raw materials, because these raw materials don't need to be purchased at all, and there are more corpses in some places than in medical schools.

Once again, I found out what a terrible woman Xu Wanjun was, when she planned to impersonate Jiang Xinyu from the ward thirty years ago, she could think of all the things that happened later, and every three people she released were useful to her.

An Rongyue's hypnotic ability can help her kill people invisibly.

Qi Chutong can help her manage Hede Medical College.

And the file of the mentally ill Cai Heqi we found last has been read, he has a serious necrophilia, and who better than Cai Heqi can help Xu Wanjun manage the corpse.

Xu Wanjun must have asked Cai Heqi to secretly use the opportunity of managing the corpse to refine corpse oil and mix it into essential oils and soaps as raw materials.

"Even if your inference is correct, it can't be true." The butcher walked back and forth a few times with his hands behind his back and stopped in front of me. "Xu Wanjun, a group of madmen, controls Hede Medical College and does nonsense, even if they use the corpses of the medical school to refine corpse oil as raw materials, how many corpses can the medical school let them refine?"

I was stunned for a moment and then realized the problem pointed out in the butcher's words, the corpses of the medical school were all donated from the dead patients in the hospital, judging from the content of the corpse oil in the essential oil, it is unimaginable that the corpses needed to refine so much corpse oil are unimaginable, and the corpses of the Hede Medical College are definitely not enough.

The butcher asked Song Chi to immediately investigate the number of corpses obtained from Hede Medical College over the years, and the figures obtained were obviously not enough to meet the amount of corpse oil in the essential oils, and from the results, the source of these corpse oils may not be refined from the corpses of Hede Medical College as we thought.

I suddenly remembered one thing, the students who came into contact with the 403 dormitory murder case and began to visit and investigate all reported that the teaching quality of Hede Medical College was very high, and it could provide a large number of fresh corpses for students to dissect experiments, and Qi Chutong was building a new and larger morgue before the incident, and I remember that he said that it was used to refrigerate fresh corpses.

We didn't care at the time, and now that we think about it, it's a blind spot, and who cares how many bodies there are in medical school, let alone where these fresh bodies come from.

I also remembered one thing, when investigating the truth of Helianyi's death, I first came into contact with Cai Heqi, when we asked him to open the morgue that Helianyi climbed into ten years ago, and the body dragged out of it happened to be used by Zhong Hui during the previous autopsy.

But I remember that it was a schoolgirl who was afraid to end up with irregular stitches, but less than an hour later, when I saw the body again, the stitches were completely different.

Obviously the same corpse why there are completely different sutures, and at that time I saw blood dripping from the corpse on the floor, Cai Heqi said that his finger was cut, but now think about it carefully, it was clearly dripping from the corpse, Cai Heqi deliberately cut his finger to cover up, the blood was very fresh and not even completely coagulated, just like the corpse that died just now, but where did these corpses come from?

Just thinking of this, Ling Guodong hurriedly came in, even forgot to knock on the door, and handed a test report to us with a shocked face, after learning that there may be corpse oil in the essential oil and soap, the butcher explained that Ling Guodong immediately tested the ingredients to confirm my inference.

"The results of the test showed that the corpse oil could not be fused into the essential oil, and it was not the corpse oil refined from the corpse fat that was mixed into the essential oil."

"Not corpse oil?" I was stunned and looked at the others.

"However, the fat found in the essential oil has been isolated and confirmed to be human fat." Ling Guodong replied seriously.

"That'...... Then this thing is bizarre, since it is not corpse oil, how can there be human fat in essential oil? Song Chi also asked in surprise.

"How did Xu Wanjun do it? How did she mix corpse oil, refined from corpse fat, into essential oils that couldn't be fused together? I frowned and muttered to myself.

The rosary in the prince's hand suddenly stopped, and the expression on his face was solemn and shocked.

"Since there is human fat, and it is not from a corpse, there is only one possibility...... The fats that Xu Wanjun et al. incorporated into essential oils and soaps are...... It's a living man! ”
