On the way back, Xiao Lianshan has been silent, his loneliness and other people's happiness for me to regain my sight formed a strong contrast, I don't know what the consequences will be after the Yin and Yang eyes that Xiao Lianshan has been afraid of will be opened, there is one thing I can still accept, at least I have the ability to protect the people around me, and I will not be like before, every time I encounter danger, they will be desperate to protect me.

I didn't tell anyone else what I saw when I opened the Yin and Yang Eyes, and even I couldn't tell whether it was a real hidden memory or an illusion, at least no matter how I looked at Han Yu, it didn't look like the golden armor god general who appeared in the picture, and as for me, I wasn't the black robe that was high up in the picture.

Maybe all this will only have to wait until the next time I see the person in the ghost market, and I can be sure that although he is not as arrogant and domineering as the person sitting on the dragon chair in his hallucination, I can be sure that he definitely has something to do with the person I saw.

After going back, it seemed that everything was back to square one, Xiao Lianshan didn't say a word about letting me go back, there was no decisive battle with the Fusang people in Genghis Khan's Mausoleum, but there must be an understanding of the bloody case of seventeen lives.

I locked myself in the laboratory for three whole days, and now the mystery I was anxious to solve was no longer what secret there was in Genghis Khan's Mausoleum, which the Fuso people had spent hundreds of years searching for.

What worries me more is what kind of person my opponent is...... Or maybe it's not human!

At present, it is certain that the original truth of the case is that Xiao Lianshan's did snipe three Fusang people outside Xie Tong's house, and the reason why their bodies could not be found was the same as the black-clothed man Xiao Lianshan killed with a silver gun in Genghis Khan's mausoleum, their corpses were all turned into ashes and disappeared in front of everyone's eyes.

The reagent bottle in my hand contains a blood sample from the side of the demise of the man in black in the Imperial Tomb, and I have been observing it repeatedly for three days, but I dare not imagine the results of what I found.

I rubbed my forehead and sat down in the chair tiredly, habitually touching my cigarette before I realized that I had quit smoking for a long time, and I sighed heavily with a tired face.

"What are the results of the blood tests?"

Nangong Yi asked seriously beside her.

"The composition of the blood is the same as that of a normal person, but the bloodstain cells in the blood sample taken are very aggressive and phagocytosis."

I licked my dry lips and said worriedly.

"When I took the blood sample, I didn't think about what else I could test, because if the comparison time was too long, the blood would completely coagulate and the best time for the test would be lost."

"And how did you find out?"

Yun Duruo asked.

I got up and picked up the slide, took a part of the dried blood sample and placed it on it, the completely blackened and coagulated blood clot was not angry at all, I used the needle to draw a drop of fresh blood from the lab rat and drop it on the other side of the slide.

Then it was placed in front of their eyes, but the moment the blood of the white rat slowly flowed and touched the dried blood clot, the black and coagulated blood clot instantly spread and greedily devoured the fresh blood and regained its vitality.

"The blood sample taken from the man in black is very bloodthirsty, and I have tried it repeatedly, no matter what method is used at high or low temperature, the cells in the blood clot cannot be broken, even if it becomes dry dead blood, once it encounters fresh blood, it will immediately recover its vitality intact."

I took a deep breath and said worriedly.

"Their blood is not only bloodthirsty, but also self-healing."

"No wonder, the last time we were attacked outside Xie Tong's house, the prince and I couldn't defeat those people no matter what method we used."

Han Yu nodded suddenly after hearing this.

"Not only can't they be defeated, but they can't even be killed, I remember using their Dongying knife to penetrate the body of one of the men in black, but I was able to pull it out unharmed."

I said with a grim expression on my frown.

"It's like they're a bunch of people who don't have life at all...... Actually, I'm not sure if they're still human. ”

"Brother, since you said you can't kill these people, then why can Dad do it?"

Because of his obsession and curiosity about Genghis Khan's Mausoleum, Gu Xiaoxiao also came back with us.

I didn't answer Gu Xiaoxiao, but picked up the glass slide and walked to the window, I asked the others to follow, I slowly opened the curtain in front of them, the bright sunlight projected in from the window, and I slowly moved the glass slide in my hand to the sun.

Multiply!

When the sunlight hit the blood on the glass slide, in an instant, the blood clot that swallowed the blood of the white rat and resurrected it rose white smoke, just like the man in black who was sniped by Xiao Lianshan, burning in front of us and soon turning into ashes.

"Sunshine...... Sunlight kills ......"

Han Yu should have understood my actions and said in surprise.

"How can there be people who are afraid of the sun?"

"Do you remember that we were attacked outside Xie Tong's house, and the large number of black-clothed people at that time had obviously gained the upper hand, if they attacked again, I believe that the three of us would not last long, but in the end they suddenly gave up and fled in silence."

The prince said to us thoughtfully.

"And at that time, the rooster was crowing and the sun was about to rise, and it was not us who they were afraid of, the reason why they retreated was because they were afraid of the sun!"

"If that's the case, then it can explain the murder involved in Uncle Xiao at the beginning of the case, witnesses said that they saw Uncle Xiao kill at dawn, and they saw him penetrate three people on a stake......"

Yun Duruo raised his head suddenly, pointed to the glass slide in my hand and said.

"The vanished corpse is just like this blood clot, which disappears into smoke when it encounters sunlight."

"But there was no sunlight when Dad killed the man in black in the imperial tomb, he just used the silver spear left by Genghis Khan."

Gu Xiaoxiao asked hesitantly.

"How did you know that this clot would die in the sun?"

Nangong Yi thought for a moment and asked intently.

"I can't figure it out as much as you do, but the properties of this blood sample are so rare that it reminds me of a disease that is extinct."

I replied calmly.

"What disease?"

Others asked.

I slowly walked back and sat down, and told the others in great detail that it was a disease that had been dead for centuries, to be exact, a hereditary blood disease, because of the cell lesions in the blood, which had strong light absorption, and the patient's skin would be sensitive to light, and the teeth would be fluorescent, which would cause severe anemia.

What's more serious is that people with this kind of lesion will have a great change in temperament, with strong aggression and bloodthirsty, there has been no radical cure before the extinction of this disease, the only thing that can be controlled and relieved is only by swallowing fresh blood, as for the reason can not be known, once the fresh blood can not be obtained, the patient will be in pain rather than life.

The specific nature of this disease is that the patient is photophobic, hates the pungent smell, is pale, has mouth muscle twitches and wants to bite something, and although this disease is a hereditary blood disease, it is contagious, and normal people who are bitten by the sick person will be infected by blood.

"Xiao Xiao asked my dad why he could kill the man in black without sunlight."

I looked at the others and said thoughtfully.

"That's because the sick don't know why, but they are afraid of anything but the sun."

"So those Fuso people are all suffering from this disease?"

The prince asked in surprise.

"That's what makes me strange, this disease has been extinct for hundreds of years, and it is not even recorded in the existing medical texts, but I accidentally saw an ancient book mentioned in my father's study when I was a child."

I rubbed my forehead and said with an anxious expression.

"However, according to the records in ancient books, this blood-borne infectious disease existed for a short time, and I don't know why it suddenly disappeared, but I tested the blood sample of the man in black and found that it was very different from the symptoms depicted in the ancient books, and I believe that this is a variant of the terrible blood-borne infection at that time, which is more perfect and terrible than the previous one."

"In addition to fear of the sun, fear of silver ......"

Nangong Yi looked at us and said meaningfully.

"Do you remember that the entire imperial tomb in Genghis Khan's mausoleum is decorated with silver, isn't it ......?"

"Yes, I've also thought about this question, before the silver in Genghis Khan's mausoleum, I thought it was Genghis Khan in order to show his identity, using silver to decorate the emperor's mausoleum, Genghis Khan's financial resources and gold should be able to set off his identity, he can completely use gold to decorate, in fact, he has the ability to do it, but he used silver!"

I nodded and continued unhurriedly.

"After I came back, I combined the blood samples of the man in black, and the Fusang people tried every possible way to find Genghis Khan's mausoleum and other signs, I think the reason why Genghis Khan used silver should not be just to decorate the emperor's mausoleum."

"The design of the emperor's tomb is incredible, there are broken ghost runes on the ground and silver is used, could it be that Genghis Khan has been wary of people suffering from this disease?"

Han Yu asked in surprise.

"In order to support my thoughts, I looked through the materials, and I remember that the ancient book in my father's study mentioned the time when the blood infectious disease broke out, the time when it had died."

I nodded and said seriously.

"This period of time coincides with the time of Genghis Khan's campaign, and it seems that there is a connection between the two."

"Even if there is a connection, or your inference is correct, why did a group of Fuso people with blood-borne infections covet Genghis Khan's mausoleum?"

Yun Duruo asked puzzled.

"Why are they trying to find this imperial tomb in every possible way?"

I stood up and took a deep breath, we had been haunted by so many secrets that we had to get to the bottom of everything before we could get to the bottom of it.

"I think there's someone who'll help us get through all the doubts."
