Time passed, and five or six hours passed.

Yu Sheng stood up, looked around, and then left the villa. Lei Jiyu saw Yu Sheng leave and hurriedly walked out of the café. However, instead of continuing to follow, he walked in the direction of his home.

When Bai Lang saw him leave the café, he went into the store to inquire.

"Who is the owner of that villa on the riverbank?"

"Oh? Be...... It's the two brothers who were tragically killed in the fast car murder. ”

"Oh? Only...... It's the ...... of the Lu brothers."

"Yes. Since the murder of the brothers, it has been uninhabited until now. The security guard locked the door and put the key next door. ”

"Hmm! That place is the ...... of the Lu family brother of the victim"

"That's right. From the outside, it looks like a villa, but in fact, they use it as a warehouse for cigarettes, as the two of them run a cigarette business with another person. ”

"They still have partners?"

"Yes, that's no, the brand of the Lu family brother Yusheng Company is still hanging at the door!"

"Who? Yu Sheng ?......" Bai Lang couldn't help but scream, the murderer Yu Sheng and the Lu family brothers turned out to be accomplices, this is indeed unexpected news.

"Yes, Yu Sheng is a red-faced man, like a vicious red devil. However, he has not been seen for nearly a year.

At this time, Bai Lang's thinking was broadened. This is a key discovery, the murderer Yu Sheng and the Lu family brothers who were killed are accomplices. But...... Why has Yu Sheng been wandering here today? Why did Lei Jiyu follow him again?......

Everything is still puzzling, and the case seems to have taken a new turn.

Shirarou monitors the movements of Regiyu's residence day and night. But a week has passed, and no shadow of Yu Sheng has been found.

On Saturday night, Bai Lang made up his mind and decided to carefully inspect the villa of the Lu brothers by the Dongjiang River.

The next day, Sunday, he guessed that Lei Jiyu or Yu Sheng would definitely come here. So, he climbed up the fence, walked through the woods in the courtyard, and entered the house through the window.

It was a small two-story building. There are two rooms on the second floor, with a lot of furniture, but they are all stacked haphazardly.

"Maybe it was messed up when the security guards came in, otherwise it was Yu Sheng or Lei Jiyu...... If the latter, why did they do it?...... What secrets might be hidden in this house,...... Aren't they already finding those secrets......"

Bai Lang pondered for a while, but there was still no reasonable explanation. He went through the house, then lay down on the bench on the second floor, and slept soundly all night.

The next morning, when he woke up, he found a book on the table, the cover bound with a black cloth. Bai Lang was interested in the black cloth, and went to the table, picked it up and rummaged through it.

"This black cloth is as thick as the black silk cloth used in the photo studio, and I seem to have some impression of it somewhere."

Bai Lang casually opened the closet again, and it was full of tattered strips of cloth and scraps of paper, and the black silk cloth like the book cover was rolled up in a ball and stuffed in a corner. Bai Lang picked it up and saw that it was three masks.

"Wonderful!" Shirarou shouted.

"Oh! The three murderers of the train fled here together, and they must have been brought in by the main culprit Yu Sheng. It turned out that this was a den of thieves. …… But...... Why did they kill the Lu brothers again? What was their motive for killing? Another mystery......"

Just when Bai Lang was puzzled, suddenly there was a sound of unlocking downstairs. Immediately after that, there was the sound of footsteps going upstairs. Bai Lang hurriedly hid in the closet and listened. A man entered the house, and after a while he went out again, and then the sound of a lock downstairs was heard.

"By the way, it could be a neighbor who takes care of the house to check it out." After Shirarou speculated, he went downstairs into the dining room and looked out through the cracks in the curtains of the restaurant.

The warm spring sun fills the courtyard. Shirarou stood there quietly waiting for something to happen. The windows in the dining room were all closed, with only a glimmer of sunlight streaming in through the cracks in the curtains, so there was not enough light.

"Ahh It's finally here. ”

I saw that Yu Sheng, who was picking up garbage, came to the door, put the big bag next to the door, and began to nibble on bread again, and was still talking to himself, but because the volume was too low, he couldn't hear what he said.

After Yu Sheng finished nibbling on the piece of bread, he leaned against the doorpost, held his pipe, and smoked it.

Bai Lang observed him for nearly two hours, but still found nothing.

"What the hell are you doing?" Bai Lang was a little impatient.

Suddenly, Yu Sheng took out the pipe in his mouth and said loudly, "Hmm! How's that, why can't I find it?"

Bai Lang was taken aback when he heard this, thinking that he was talking to himself. Looking at it, Yu Sheng's eyes were staring at the surface of the Dongjiang River, muttering in his mouth.

No, he's not muttering, he's talking to the unseen.

"Hey, look closely, you'll find it, and then look through the left side of the basement...... I've already looked for the right side last time,...... What?...... No?...... Where the hell is hiding?......, there is nowhere else to hide but here. ”

An hour passed, and Yu Sheng spoke:

"Why haven't you found it yet?...... Feed! It's really troublesome, and then look for it somewhere else. I've ever played with that bottle in my hand, and I won't do without it.

"The two brothers probably left the bottle somewhere before they went out,...... Go to the backyard and rummage through it, there's a waste heap there. Although Lei Jiyu turned over the basement, he may have neglected the courtyard, because the courtyard is more inconspicuous than other places, so let's look for it thoroughly! ”

"Strange...... Who is he talking to?"

Bai Lang took a closer look, and it turned out that Yu Sheng was leaning his mouth against the stone under the doorpost, shouting loudly.

"Hmm! There was a vent in the basement, and he was using the crack in the stone to order the man. ”

When Hakuro understood what they were doing, he turned to the window where he could monitor the backyard.

The backyard is full of scrap items, including scrap metal pieces, empty boxes, empty cans, dilapidated furniture, etc., piled up in a mess.

There was a little boy, about 7 or 8 years old, who was rummaging through that big waste heap.

After a while, the child picked up a notched bottle, smiled as he wished on his dark, dirty face, and ran towards the gate.

"Oh! Great, I finally found it. Hum! This time, Lei Jiyu's guy is going to fail again, as long as he has this bottle, everything is in the bag! Great, come on, let's get out of here. ”

Yu Sheng opened the big bag next to him, let the child get in, and then walked away with his legs on his shoulders.

"Hey, there's a hand, and he's up to this idea. But what's the big secret in that broken bottle?"
