From Ye Xianguo's chaotic description later, I also roughly understood what happened at No. 37 L Mansion back then, and the truth of that strange case.

However, what I didn't expect was that through Ye Xianguo's narrative, the murderer of the black gold case, who disappeared at the beginning, resurfaced!

More than 30 years ago, when China was in the early stages of development, technology and basic education lagged far behind other countries in the world, and crime rates across the country remained high.

At that time, Ye Xianguo had just returned from studying abroad, and after seeing the backwardness of the motherland, he immediately made up his mind to serve the motherland with all his enthusiasm.

Ye Xianguo was abroad, mainly engaged in the research of behavioral psychology and criminal psychology, and after returning to China, it coincided with the beginning of the "indoctrination field" program. With the advantages of professionalism and knowledge, Ye Xianguo naturally devoted himself to the research of the plan.

As for his wife and two children, Ye Xianguo temporarily arranged for them to live in his ancestral home, No. 37 L House.

This Western-style mansion was originally left by Ye Xianguo's parents during the war. There is a huge underground air-raid shelter built under this western-style building, which was mainly used for sheltering the surrounding residents at that time and transporting materials during wartime.

Later, due to the resumption of the "Indoctrination Field" project, this underground bomb shelter was built as a new laboratory for a new round of experimental research, of course, this is a story for another time.

Because considering the concealment of the whole plan, all the researchers must conduct research and investigation in the closed underground research institute, considering the fact that Ye Xianguo has a family and has two children, the institute decided to give Ye Xianguo a period of vacation every once in a while, so that he can have enough time to go home to visit his wife and children.

From this point of view, there are many similarities with my father's situation.

Originally, the experimental plan was smooth, and Ye Xianguo's wife and children lived comfortably in the foreign pavilion, however, on a rainy night, all this peace was broken by two uninvited guests.

Ye Xianguo clearly remembered that night, the typhoon had just passed, the wind was curling and the heavy rain was constantly blowing on the earth, and the lightning and thunder in the sky were constantly roaring, as if the world was apocalyptic.

That day, Ye Xianguo happened to stay in the Western-style pavilion to accompany his wife and children, and after comforting the children to fall asleep as soon as possible, he also went downstairs to wash and prepare to rest.

At this moment, there was a faint knock on the door near the hall. The sound was faint, but continuous, and it was extremely strange on such a rainy night.

At first, Ye Xianguo thought that he had misheard and mistaken the sound of the wind for a knock on the door.

But after a while, the knocking on the door continued, and there was a faint shouting in it, which finally aroused Ye Xianguo's vigilance.

With such a heavy rain outside, what kind of people would deliberately come to this mansion to look for him, could it be because there was an emergency in the institute? It is possible that, after all, because of the heavy rain, the telephone line is not working properly.

Ye Xianguo didn't dare to wait any longer, walked to the door in three steps and two steps, pressed the handle, and opened the door.

In an instant, the wind swept into the hall with the heavy rain howling, and for a moment, Ye Xianguo's front was pitch black, and his vision was completely gone.

At this moment, a thin black shadow rubbed against Ye Xianguo's shoulder, rushed directly into the room, and then fell to the ground in the hall, trembling.

The movement disturbed Ye Xianguo's wife, because her wife had also settled abroad for a long time, and because she was afraid that her husband would be in danger, she instinctively took out the double-barreled shotgun on the second floor of the mansion and went downstairs to check the situation.

When the two of them entered, they found that the thin fellow was covered in rain, and his messy hair, after being wet by the rain, was spread out in all directions, and the coarse linen clothes he was wearing had already become tattered.

Could it be that he is a homeless man outside, because of the sudden rainstorm outside, so he plans to go into the house to hide from the rain?

Ye Xianguo and his wife are also reasonable people, and not far from the foreign pavilion, there is a temporary shelter dedicated to the relief of such homeless people. In the past, when this happened, they would take the homeless person to the shelter next door, and leave some money for them to live on for a while.

Just as Ye Xianguo was about to step forward to pull up the homeless man, at this time, he was surprised to find that the homeless man was actually holding a six-year-old child in his arms.

The child's eyes widened, looking at Ye Xianguo on the side expressionlessly, while the homeless man on the side kept waving his arms, talking hesitantly, and kneeling down and kowtowing emotionally from time to time.

From the moment Ye Xianguo saw the three-year-old child, an indescribable emotion slowly rose from the bottom of his heart, because this six-year-old child was so special.

The child's face was pale, and his whole body was extremely unhealthy blue-white. His eyes did not have the slightest brilliance, the dark circles under his eyes were serious, and his face was expressionless, which was like an old man who had experienced the world and looked down on the world.

What's even more terrifying is that the corners of the child's mouth are full of bright red. Despite the heavy rain, the red color is still noticeably strong, and there are some animal feathers sticking around the corners of the mouth, which makes people shudder just by looking at it.

The child stared at Ye Xianguo, and Ye Xianguo looked at the child silently. From this moment, many things were quietly planted.

Among them, this world is like that. Some people, some things, in the dark, have long been predestined.

After a period of sign language exchange, Ye Xianguo learned that the man in front of him was named Jiang Acai, who was deaf and mute, and the child he was holding in his arms was named Jiang Sheng, who was six years old this year.

Jiang Acai was originally a person from the north, although he was born with a disability, but with his hard work, the family lived quite comfortably, but this originally comfortable life was broken from the birth of this little boy.

Since he was born, Jiang Sheng has suffered from a strange disease, his skin is whiter than ordinary people, and he hates sunlight and likes night. If he stays in the sun for a long time, his skin will become blistered, which is very frightening.

What's even more terrifying is that since he was a child, Jiang Sheng has been fond of drinking blood. Once, when his mother was breastfeeding, Jiang Sheng, who had just developed baby teeth, even bit his mother's breasts directly, sucking the blood into his mouth along with the milk.

Jiang Acai's wife is an authentic peasant woman, and after seeing Jiang Sheng sucking animal blood many times, she finally couldn't withstand the pressure and hanged herself.

After that, the notoriety of their father and son spread. The people of the village regarded them as demons and expelled them from the village. For so many years, Jiang Acai took Jiang Sheng to wander around, wanting to seek a famous doctor for treatment, but now, the money is almost spent, but Jiang Sheng's condition has not improved in the slightest.

Because of Jiang Sheng's illness, the two of them could only rest during the day and move at night, but unfortunately, they happened to encounter a storm today.

The desperate father and son heard that there was a kind family living in the Western-style house here, specializing in helping the poor. That's why they rushed here in the rain, hoping that Ye Xianguo and his family could show mercy and help their father and son.

According to the past practice, when encountering such a homeless man, Ye Xianguo and her wife and children took them to a shelter not far away.

However, because of Jiang Sheng's strange illness, Jiang Ah was afraid that after going to the shelter, he would be ostracized by other homeless people, so he insisted on not going there.

Despite this, Ye Xianguo's wife and children still did not agree to let the father and son stay. First, it is inevitable that the neighbors will gossip. Second, Jiang Sheng's strange illness may affect the safety of their children.

Although he couldn't speak, in order to pray for Ye Xianguo's acceptance, Jiang Acai almost broke his head. In desperation, Jiang Acai even pointed to the kennel on the edge of the foreign pavilion, saying that if the Ye family could take in their father and son, Jiang Acai was willing to guard the door for the Ye family like a watchdog.

At this moment, another thunderclap streaked across the sky. Looking at the pouring rain outside the house, Ye Xianguo finally made a decision.

It was precisely because of this decision that the entire Ye family fell into a situation from which they could never recover.
