As soon as Xu Yao returned to Kangsar, he made the investigation of Li Tieer's identity a top priority. He sent Liu Xiaobo, Lao Tan, Xiao Lizi and other capable officers to investigate Li Tieer's whereabouts.

Li Tieer disappeared from Lijia Village. After three police officers' sleepless investigations, they also went to Li Village to conduct interviews and investigations, and retrieved video footage from that year.

After three days of investigation, a breakthrough was made. Liu Xiaobo and his team worked together to find Li Tieer.

He followed an American to a town in California, USA. His adoptive father was named Johnson, and they also found Johnson's address.

After Liu Xiaobo informed Xu Yao of the news, Xu Yao immediately set off again and headed for Johnson's hometown.

This time he also asked Mo Xiaoqing to follow him. After all, she had been involved in these cases, and it would be safer to have her by his side to help.

They took a flight the next morning and went directly to California, USA. It was already 4:30 in the evening when they arrived at their destination.

Mo Xiaoqing felt exhausted because she couldn't adjust to the jet lag, but they didn't rest, but went directly to the house where Johnson lived.

After arriving in that town, Xu Yao had no problem communicating in English. He asked the residents in the town and learned that Johnson's house had not been lived in for a long time, and Johnson had disappeared a few years ago and has not been found so far.

At five o'clock in the afternoon, US time, Xu Yao and Mo Xiaoqing stood in front of Johnson's overgrown house.

After they took a deep breath, the two pushed open the dilapidated gate and walked in.

The furnishings in the house were very simple, with a closet on the left and a desk. There was also a very large wooden bed with a Mousse mattress on it, which was already in tatters. At the same time, there were clothes scattered all over the closet, and they were damp and rotten.

Xu Yao used a piece of wood to pick up the clothes that had been thrown on the ground and checked them. They were vests and trousers.

The TV was empty. There were a few pencils and paintbrushes in the drawer, and there was a professional drawing tool box next to it.

There were dozens of sheets of drawing paper piled up on one side of the room, some of which had fallen to the ground and rotted into waste paper.

There was no one living in this house, so the bedding on the wooden bed was dirty and messy, and it had become a home for rats.

Xu Yao looked around carefully and didn't find anything extra. Just as Xu Yao was lost in thought, he felt Mo Xiaoqing gently pulling him,

"Captain Xu, look!"

Xu Yao looked in the direction Mo Xiaoqing pointed, and he found that there was a different dust mark on the ground, and there was also a square scratch on the ground that extended to the bottom of the wooden bed.

Is there something on the wooden bed?

Xu Yao pushed the wooden bed with his hand, it was not very heavy, and it could be moved. He asked Mo Xiaoqing to stand on the other side of the bed and help him move the wooden bed to the side.

Suddenly, a dark object appeared. Xu Yao took a flashlight and shone it inside. He saw several open wooden boxes, which were filled with a lot of miscellaneous items, including old books, various machine parts, and various papers.

Xu Yao asked Mo Xiaoqing to bring tools. He knocked on the boxes for a long time, but did not find anything special. Just when he was disappointed, he suddenly found that the cement floor under the wooden boxes felt hollow when he stepped on it.

Xu Yao once again pulled the wooden box open and dragged it to the side, while shining the flashlight downward.

Unexpectedly, a handle suddenly appeared on the ground.

Mo Xiaoqing stood by and couldn't help but exclaimed: "Captain Xu, is there another hidden room behind the back door?"

"Let's go and take a look."

The two of them worked together to move all the other wooden boxes away, and soon a cellar entrance about one meter wide was exposed under the light of the flashlight.

The door was not locked, but there was a rusty copper lock hanging on it.

Xu Yao tried to force the copper lock open with his hands, but found that he could never do it. Mo Xiaoqing quickly turned around and walked out of the room, found a stone outside the house, walked in and handed it over.

Xu Yao took the stone and grabbed the copper lock, and pounded it down heavily. With a creaking sound, the wooden door was opened, and a pungent musty smell came towards him.

Mo Xiaoqing quickly held her mouth tightly with her left hand. Even Xu Yao couldn't help sniffing and frowning.

Xu Yao shone the flashlight inside and found a rusty iron ladder under his feet. He stretched out his right hand to hold Mo Xiaoqing's hand tightly and tried to climb up the iron ladder. He touched the iron ladder slightly and felt it was shaking violently.

However, the iron ladder should not collapse immediately. He bit the flashlight in his mouth and climbed down step by step.

The person who loosened his hand would cry like a chicken, and slowly pull down like taking medicine.

Mo Xiaoqing was panicking, but as long as Xu Yao was by her side, she was much braver.

In less than half a minute, the two of them were standing directly on the open space in the cellar.

The cellar was not big, about 7 or 8 square meters, and maybe 2 meters high, with a large open space in the middle. The walls were all piled with rotten wooden boxes, and there were many papers on them, some with drawings on them.

Mo Xiaoqing walked over with a flashlight and carefully flipped through the pictures. As soon as she turned over a picture, she couldn't help but scream and backed away.

Because the pictures in the pictures were so hideous and terrifying, with blood-like paint colors, painted with hideous faces, and the background of the pictures was blue and black.

Xu Yao came over and asked, "What's wrong with Mo Xiaoqing?"

Mo Xiaoqing calmed down and replied, "It's okay, I was just scared by the painting. But the style of this painting is indeed very similar to the style of the paintings I saw in the gallery, but the paintings here are more hideous and more disgusting."

Mo Xiaoqing said while suppressing her fear and continued to flip through the paintings piled on the wall.

She really didn't feel anything about these paintings. If a person faced these paintings for a long time, it felt like a normal person would suffer from depression and become mentally confused.

What these paintings presented was very depressing.

When Xu Yao heard these words, he couldn't help but sigh: Sometimes works of art can kill people, I think this is true.

Mo Xiaoqing then remembered that when they went to investigate Li Tieer's junior high school teacher in the United States, he had also said the same thing.

It is likely that Li Tieer's junior high school teacher had already discovered Li Tieer's mental abnormality at that time. If

a person paints depressing paintings and depressing and terrifying portraits for a long time, then it is very likely that these are the most true portrayals of his inner heart.
