As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

correct!

Ye Lin suddenly realized that Chen Dachun was probably going to the back mountain to get the money, otherwise he would have gone directly back to the village and not had to go into the mountain at all.

That means Chen Dachun was the one who killed Ling Hai.

I was so confused that I was still wondering if it was Chen Dachun who killed someone.

On the evening of the 14th, Chen Dachun killed Ling Hai and buried him behind the mountain temple. The bag of money was so big that he probably didn't take it home directly.

Because Chen He's parents were looking for trouble with him at that time, and the police might come to his house at any time.

Therefore, it was impossible for Chen Dachun to take the money back, and hiding it was the most reasonable approach at the time.

This makes sense. Chen Dachun hid the money in the mountain temple, and then came back on the night of the 15th to get the money. It is unknown who found him, but it is likely that they had a dispute over the division of the money, which led to his death.

After sorting it out like this, Ye Lin felt much smoother and it completely matched the current clues.

Now what we need to find is the person who discovered Chen Dachun going up the mountain that night.

Who would go to the back mountain and run into Chen Dachun at around 8 o'clock in the evening?

Ye Lin really couldn't think of it.

Generally speaking, Chen Dachun is not a fool. If he wants to take the money, he will definitely look around.

So, if he just happened to come across it, he would probably just brush it off.

Then the murderer must have been lying in wait for him, and then showed up when he saw him taking the money.

In this case, the people of Shangliang Village are not so suspicious.

It was thought that on the 15th, Chen He's family went to Fourth Uncle's house to make trouble. Everyone knew that Chen Dachun went to the city, and no one knew that he would go to the back mountain, so it was impossible to ambush him.

Even Chen He's parents, who hated him the most, didn't know that he would come back.

Therefore, Ye Lin felt that he should turn his attention to the outside of Liang Village.

When Ye Lin thought of the people outside, two names suddenly popped up in his mind: Wang Zhiqiang and Zhang Quanhai.

According to the information currently available, Chen Dachun did not contact many people after the murder on the night of the 14th. Among them, Wang Zhiqiang and Zhang Quanhai were with him throughout the day on the 15th, and they are definitely the most suspicious.

It is very likely that Chen Dachun let the secret slip, and the two men followed him to the back mountain, killing people and robbing them of their money.

"Wang Longxin, check Wang Zhiqiang and Zhang Quanhai."

“看看这两个人这5年里的经济状况，还有找112路公交车，看5年前7月15号晚上有没有司机记得他们。”

"Or is there a taxi that can remember picking them up."

Wang Longxin looked bitter, "Captain Ye, I can check the buses, but where can I check the taxis? We have so many taxis in Yuezhou, and I don't know how many taxi drivers have changed in the past five years."

Ye Lin pursed his lips. Indeed, taxi drivers are different from bus drivers. Bus drivers are more stable, while taxi drivers are mobile and indeed difficult to check.

"Forget it, I won't check the taxi drivers. I'll check the others, mainly to see if there's any sudden large income."

"Okay, this will be checked quickly, just wait."

Wang Longxin took people to investigate without saying a word.

And the fact is just as he said, it happened very quickly.

After most of the day, Wang Longxin rushed back excitedly, "Captain Ye, I found them. You guessed it right. These two guys were unemployed youths before, and then they suddenly became rich."

"Really? Tell me in detail." Ye Lin pulled Wang Longxin to sit down.

"Captain Ye, I found out from other classmates of Chen Dachun that Wang Zhiqiang and Zhang Quanhai's family conditions are not that good, and are about the same as Chen Dachun's."

"They were both unemployed five years ago, so they spent so much time playing games in the Internet cafe with Chen Dachun."

That’s true. Generally speaking, people who work properly would not go to an Internet cafe to play for a whole day.

"But I don't think Wang Zhiqiang is a rich man." Ye Lin said. The last time they met, it was obvious that Wang Zhiqiang was living in poverty, while Zhang Quanhai was living better.

"I checked. Here, look at this." Wang Longxin took out a real estate transaction record from his bag.

"This is the record of Wang Zhiqiang buying a house five years ago. He paid a down payment of 5 million to buy the house, and now he has to pay the mortgage, so he feels a little short of money."

Ye Lin took it and looked at it. "This is a 140-square-meter house. Wang Zhiqiang bought a luxury house."

"Yes, it is said that Wang Zhiqiang was dating his wife at the time, and his wife demanded a big house before marrying him. How could they afford it given their family's financial situation?"

"But no one expected that he would buy it suddenly, and several classmates were very surprised," Wang Longxin explained.

"What about Zhang Quanhai? What happened to his money?"

"Zhang Quanhai is a person who enjoys life. He rents a house and then five years ago he suddenly bought a BMW and a famous watch. His classmates don't know where his money came from."

"Please ask them to come back. Even if their classmates don't understand, they themselves should understand." Ye Lin said.

......

"Wang Zhiqiang, you bought a house five years ago, a big one at that. As far as we know, your family probably doesn't have that much money. Can you explain where this money came from?" Ye Lin asked Wang Zhiqiang opposite him.

After confirming that the two were suspects, Wang Longxin quickly brought them back and had Ye Lin interrogate them separately.

Facing Ye Lin's question, Wang Zhiqiang remained calm, "Officer, this is what I earned from my investment."

Ye Lin chuckled, "What kind of investment is so profitable? Take me with you to try it."

"I bought Bitcoin, but now the transaction is not allowed, so I can't take it with me. I'm sorry, officer." Wang Zhiqiang said calmly, with no expression on his face.

Too calm, so calm that it seems fake.

A normal person would stutter when facing police questioning even if he didn't feel guilty, but Wang Zhiqiang spoke very fluently, as if he had memorized it in advance.

And I believe he has been thinking about this reason for a long time.

Bitcoin, a type of virtual currency, has always been discouraged by the country. One reason is that there are no transaction records and it is difficult to track.

Another is that price changes are too great, with sharp rises and falls being common, which is not very friendly to countries that hope for stability.

So later the country banned the trading of virtual currency.

Now Wang Zhiqiang says that he made money from Bitcoin, and even if Ye Lin has all the means, he won’t be able to find out.

Lin Feng looked at Wang Zhiqiang, and Wang Zhiqiang looked at Ye Lin, and the two of them just looked at each other silently.

"Wang Zhiqiang, you said before that on July 7, after you had dinner, Chen Dachun said he wanted to go back to the village to get the money, right?"

"Yes, that's what Dachun said."

"What about you? You didn't go with them?"

"Why should we follow?" Wang Zhiqiang asked back.

"Where did you go then?"

"Go home and sleep."

"Can anyone prove it?"

Wang Zhiqiang smiled and said, "Who can prove that I went home to sleep?"
