Black evidence is a witness system established after the establishment of PW to investigate corruption and irregularities within the police, similar to the so-called "tainted witness" in Western countries.

In the beginning, black evidence only refers to black police officers who know the law and break the law, but can provide major clues to PW. Later, the black certificate was not limited to the black police, but also expanded to other scopes, as long as it can provide major clues, PW can help him reduce his sentence according to the situation, or directly get rid of the crime and help him change his face and start a new life.

The former is usually in prison, but the latter is free, so it can be seen that Xiangsha is supposed to be the latter.

Wei Chi speculated: "I see, you have participated in military experiments. ”

Xiangsha nodded slowly: "That's right, but I was forced to be unaware, and after I knew, I chose to quit." ”

Fang Xunyi looked disbelieving: "Quit? Will they let you go easily? ”

Xiang Shadao: "What I mean by quitting is just quitting the front line, and what I do is just helping them find some raw materials they need, including a lot of strange creatures and plants. ”

Fang Xunyi and Wei Chiran both looked at Xiangsha, and now they finally understood why Chu Xia chose him to come, and this matter was far from being as simple as Chu Xia said, it seemed that it was not only to explore the jungle past of Meng Gong Mansion, but also had other purposes.

In addition, when Chu Xia and Wei Chi Ran talked, they didn't let Xiang Sha stay on the spot, which also shows that Xiang Sha may not know that Chu Xia is the lone army that infiltrated PW.

The lieutenant chisely asked, "What is the military's experiment?" ”

Xiang Sha said: "As far as I know, it is the physical adaptation experiment of soldiers, which began during the American-Vietnamese War, when there was a rumor that North Vietnamese soldiers with extremely physical fitness were found on the battlefield. ”

Wei Chiran asked, "What do you mean?" ”

Xiang Sha explained: "After the North Vietnamese soldier was caught by the South Vietnamese side, he was tortured, and he was locked in a water prison for about a week, his skin was soaked and rotten, and the people he was imprisoned with him had long since died, but he was still alive, and his recovery ability was particularly strong, so this person was taken away by the US military, trying to find the secret hidden in him, why his recovery ability is so amazing, and he can not eat, drink or sleep, and the experiment between the military and the US military began at that time." ”

No eating, drinking, no sleeping? And extremely resilient? Isn't this Fang Xunyi?

Wei Chi subconsciously glanced at Fang Xunyi next to him, but Fang Xunyi's face was ugly.

Fang Xunyi is a memory that he has since 1944, and the time when the US-Vietnam War began was 1955, could it be said that Fang Xunyi once participated in this war by accident?

But Wei Chi couldn't ask Fang Xunyi now, so he had to turn his attention back to Xiangsha and ask, "And then?" ”

Xiangsha shook his head and said: "I don't know much about the truth, I know that the military and the United States have been experimenting for many years, after the end of the American-Vietnamese War, the United States withdrew, but the military is still conducting experiments in private, but because the United States took away a large number of materials, they are tantamount to starting over, but there has been no breakthrough, and the laboratory has been closed, until after the appearance of human corpses in Chinatown, the military reopened the laboratory, and I was one of the soldiers recruited at that time." ”

Wei Chiran sighed in his heart when he heard this, could it be that his previous speculation was wrong? The military was not behind the beginning, but after Gan Le created the human corpse, the military restarted the plan?

Xiangsha said: "Because the information on the human corpse is in the hands of PW, the military can't get it at all, and it can't cooperate with an independent department like PW, so it can only find another way." At that time, Xiangsha was only responsible for the perimeter protection of the entire experiment, looking for some strange creatures and plants in the jungle for the military to experiment, but he didn't know exactly what they were doing.

However, Xiangsha quit the unit because one of his team members turned into a human corpse after voluntarily undergoing the experiment, and it was then that he learned that the military was conducting horrific human experiments.

Fang Xunyi wondered: "You only knew at that time?" ”

Xiangsha nodded: "Yes, I always thought that the military was just an ordinary biological experiment, for the purpose of anti-drug and anti-drug conduct, they told us how to permanently quit drug addiction, until something happened to my team members, I realized that things are not so simple, so I launched a basic investigation, and then also applied for retirement, the military agreed to my request, but, what I didn't expect was that in fact, I had already become one of the subjects of the experiment......"

Xiang Sha said that he had already become an experimental subject, which surprised Wei Chiran and Fang Xunyi.

After retiring from the army, Xiangsha used the money he had saved to buy a farm, and married a local girl to live an ordinary life, and the two had a child in the second year of marriage, but the child died on the eve of his first birthday, and the doctor informed the child that the child was suffering from acute encephalitis.

At this time, the military sent someone to find Xiangsha again, hoping that Xiangsha could return to the team, because the military still needed people like him, but Xiangsha Yan refused.

In the third year, the two had another child, whom they took good care of, and this child was also very intelligent, from birth to the age of five, he almost never got sick, and his body was very healthy.

But when he was five years old, Xiangsha's son died suddenly, very suddenly in front of the two couples.

At the same time, Xiang Sha also learned from his comrades-in-arms who came to visit him that the three people they retired together were all in much the same situation as him, and the children all died shortly after birth.

The trio immediately realized that perhaps what was happening now had something to do with the military's experiments back then, because every month the military asked them to be vaccinated against the so-called jungle disease.

Xiangsha's wife died of two children one after another, and eventually suffered from depression and committed suicide.

Elephant Sha's life is completely broken, and he decides to take revenge on the military, but before he is ready to do it, he is approached by PW's people, who hope that Elephant Sha can cooperate and uproot the cancer of the military race.

Later, as PW speculated, the military approached Elephant Sha again, hoping that Elephant Sha would serve the military as a civilian, and find strange creatures like corpse ants in the jungle for the military, and they would pay several times higher than the price on the market.

In order to take revenge, Xiangsha had to agree, and hoped to take the opportunity to slowly dig out the secrets of the military.

After listening to this, Wei Chiran said: "The military is not a vegetarian either, you cooperate with PW, it is impossible for them not to know the news, you are still fine, don't you think it's strange?" ”

Xiangsha said: "I don't know where to start, so I can only follow PW's instructions, and I will do whatever they tell me to do, as long as I can take revenge, I can do anything." ”

Wei Chiran didn't say anything after listening to it, he just felt that although Xiangsha's series of experiences were bizarre, there were many places that were illogical.

First of all, how could the military approve Xiangsha's request for decommissioning so simply?

Secondly, at that time, PW knew about the experiments done by the military, why did it not move at all? On the contrary, start with Xiangsha, a person who can't access the core secrets?

Moreover, Xiangsha cooperated with PW, didn't the military's intelligence agency know about it, and it stands to reason that Xiangsha would have killed people a long time ago, so why should he be kept?

After these three questions appeared in his mind, Wei Chiran asked again: "Who is the person with whom the military has come into contact with you?" ”

Xiangsha shook his head: "I don't know, it's different every time, they don't communicate with me, they just take things and leave, and they give a lot of money every time." ”

Although the matter of Xiangsha is another clue, this clue is too vague.

Moreover, Wei Chiran has suspected that there is something wrong with PW so far, and the purpose of Chu Xia and Hou Wan does not seem to be so simple.

Wei Chiran looked at Fang Xunyi, but found that Fang Xunyi seemed to be distracted, he didn't know what he was thinking, he really wanted to communicate with Fang Xunyi, but because of the presence of Xiangsha and Guan Hongru, he had to hold back.

At this time, the fog in the swamp had reached the highest position, and the four people sitting there had to get up, if they didn't stand up, they would all be shrouded in thick fog, but even if they stood up, invisible fear still filled his body.

I don't know if it's because of the fear or why, Wei Chiran always feels that something is wandering around, and he can always hear some strange sounds.

Wei Chi couldn't help asking: "Sir Fang......"

As soon as he said a few words, Fang Xunyi interrupted him and said, "Don't call Fang sir, okay?" You can tell us to find memories or even to find memories. ”

Wei Chiran said: "Okay, I'll call you Lao Fang in the future." ”

Fang Xunyi looked at Wei Chiran a little helplessly: "Okay, as long as you don't call Fang sir, you can call it anything." ”

Wei Chiran pointed ahead and said, "Did you hear any sounds?" ”

Fang Xunyi listened carefully for a while and said, "No, it's quiet." ”

Wei Chi covered his ears and let go: "I'm sure I heard it right, I can't hear it if I cover it, and I can hear it again when I release it, it's not an auditory hallucination, and it's not a voice in my head." ”

Xiangsha looked into the fog and asked, "Is it like someone whispering in your ear?" But you can't hear what you're saying. ”

Wei Chiran hurriedly said, "How do you know? Did you hear that? ”

Xiangsha said: "Yes, every time I come to this swamp, I can hear this sound, it's so strange. ”

Wei Chiran hurriedly looked at Fang Xunyi and Guan Hongru: "Can you two hear it?" ”

Guan Hongru shook his head, but Fang Xunyi was distracted, as if he was thinking about something, and when the lieutenant touched him and asked again, Fang Xunyi shook his head and said that he couldn't hear it.

Why can only I and Xiangsha hear it? Wei Chi felt strange, but strange couldn't suppress his curiosity, after all, his curiosity drove him to do many things that he couldn't even understand afterwards.

Almost at the same time, Wei Chi realized a very serious problem - the surrounding environment had changed.

The lieutenant looked around, left and right.

Fang Xun recalled his appearance and asked, "What are you looking at?" ”

Wei Chiran pointed to the left side and said: "There was a low tree on the left before, and there was something like a bird's nest on the tree, but now it is gone, and there is a tree directly in front of me, at least five meters away, there is only one tree, and now it has become three trees, and the trunk looks different." ”

Xiangsha and Guan Hongru also looked around, Guan Hongru shook his head and said, "I didn't pay attention to these." ”

Xiangsha was reminded by the lieutenant lately, but he also realized: "Yes, before we were directly in front of us was the road when we came, and there was indeed only one tree, how did it become three now?" ”

Wei Chiran stood there and looked around, and suddenly found something, pointed to the right side and said, "Do you see that tree?" There was something like a bird's nest on the branch, and I remember the tree, which was clearly on our left side! ”
