I can dream about my own death.

Upon hearing the words "fishy smell," Chen Wensheng immediately thought of Lao Zhou.

Old Zhou runs a fish stall and spends his days cleaning fish, so he always has an inescapable fishy smell about him.

In addition, yesterday, he saw a person wearing a baseball cap at the sewer construction site who looked almost identical to Lao Zhou.

According to criminal psychology, many criminal suspects return to the scene of the crime after committing it, either to admire their "masterpiece" or to gather information.

If the person he saw was Lao Zhou, then Lao Zhou could really be a prime suspect.

Li Mubo talked on and on, but Chen Wensheng didn't hear a word of what followed.

Two minutes later, Li Mubo finally finished speaking.

Li Yucheng and Wang Feng both nodded in agreement, while Chen Wensheng stood there expressionless.

Li Mubo immediately noticed Chen Wensheng's unusual behavior and asked, "Did you connect this to something? Can you explain your deduction?"

Chen Wensheng came to his senses. His suspicions were just that—suspicions—lacking any concrete evidence. Besides, he had a good relationship with Lao Zhou, so he decided not to cause Lao Zhou any trouble and said with a smile:

"I was just thinking about why the suspect would use aqua regia to dissolve the gold. Was it to smuggle the gold out of Changfeng City undetected in its liquid state?"

Li Mubo immediately realized what was happening, his eyes lit up, and he said excitedly:

"Your words have given me a new perspective. Aqua regia is extremely corrosive; it can dissolve and corrode even inert metals like gold and platinum."

"If we want to transport this aqua regia containing dissolved gold out of Changfeng City, we must use extremely special anti-corrosion materials."

"At the crime scene in the sewer, I found polytetrafluoroethylene (PEFT), also known as Teflon, a special plastic that is not corroded by aqua regia."

"Based on this, it is highly likely that the suspect used this type of plastic to store aqua regia containing gold."

"The suspect transported the gold-containing aqua regia to another location via pipelines and then collected it."

"This also means that there must be a plastic container at the other end of the pipeline to collect and store the aqua regia."

"We can find criminal suspects by checking the purchase and sale of Teflon, a high-value plastic."

As soon as he finished speaking, Li Mubo ran off to tell his other colleagues about it.

Li Yucheng turned to Chen Wensheng and said, "Wensheng, being a reporter is really beneath you. With your abilities, you should be a policeman or a detective; that would allow you to fully utilize your talents."

Chen Wensheng replied sheepishly, "Don't make fun of me. I just said whatever came to mind; it was a sudden inspiration, nothing I had thought about deeply. It just happened to trigger Detective Li's association."

Once he had a direction for breakthrough, Li Mubo had no time to pay attention to the three of them.

The three waited at the police station for more than half an hour, but still couldn't see Li Mubo again.

Chen Wensheng was getting impatient and asked, "Nobody's paying attention to us now, we can't just keep waiting, can we?"

"As long as no one tells us the interview is over, we'll just keep waiting. It's warm inside, but it's freezing outside. We might as well just kill time here instead of wandering around outside." Wang Feng wanted to slack off.

Li Yucheng nodded, feeling that what he said made sense. After all, today's interview had yielded great results, and it could be said that the task had been exceeded. It would be nice to spend the rest of the time relaxing in the police station.

Looking at the snowflakes falling outside the window, Chen Wensheng's impatience immediately dissipated. It was too cold outside; it was much warmer inside. He decided not to suffer unnecessarily.

.......

More than two hours later, Li Mubo reappeared and said to the three of them, "You haven't left yet?"

The three of them, who were slacking off, looked at each other.

Then, Li Yucheng replied with a slightly flushed face, "We are professional reporters. Since we have followed up on this gold heist, we must get to the bottom of it."

"Oh! It's lunchtime. Let's grab a quick bite at the cafeteria. After a morning of investigation, we've got a new lead. Later, a few colleagues and I are going to the market to conduct further investigations. You can come along too," Li Mubo said with a smile.

"Thank you," Li Yucheng said, and then went to eat.

After finishing his meal, Li Mubo went straight to investigating the case without even taking a moment's rest.

Chen Wensheng and the other two ate too slowly, so they had to put down their half-eaten food and follow behind Li Mubo.

On the way, Chen Wensheng asked, "Officer Li, why are you going to the vegetable market to conduct an investigation?"

"After a morning of investigation, we discovered a very unusual order: a fishmonger spent a large sum of money to purchase a large quantity of Teflon plastic products. Since buying these products, this fishmonger has completely disappeared from the market, no longer selling fresh fish. Therefore, it's necessary to investigate the fishmonger's business partners to see if we can find any useful clues," Li Mubo explained.

Chen Wensheng nodded: "It is indeed suspicious that fishmongers are buying Teflon plastic products at high prices."

So the group went to several vegetable markets in the city and inquired at numerous fish stalls, but to no avail.

More than three hours later, at 4 p.m., the group arrived at the last vegetable market in Changfeng City to conduct their investigation.

This vegetable market is located in the slums of Changfeng City, surrounded by low-rent housing and urban villages. The market is relatively small and the sanitation conditions are poor.

Li Mubo didn't have high hopes for this vegetable market, but as a meticulous criminal police officer, he still didn't let it go.

Chen Wensheng often comes to this vegetable market to buy vegetables and is very familiar with it, so he walked ahead.

When Li Mubo first saw Chen Wensheng walking ahead, he asked, "Have you been to this market before?"

"My family lives in Chenxing low-rent apartments, and we usually come to this market to buy groceries."

"oh."

"I'm familiar with this market, follow me." Chen Wensheng led the group towards the fish stalls.

After arriving at the fish stall, Li Mubo asked the fish stall owner questions one by one.

After a routine inquiry, Li Mubo found nothing unusual and prepared to leave.

As he was leaving, Chen Wensheng said to the fish stall owner, Lao Zhou, "Lao Zhou, as usual, give me a tilapia."

Upon hearing this, Li Mubo immediately stopped and turned to look at Old Zhou's fishpond, where he saw white steam billowing from it.

"No, tilapia are southern fish and are particularly intolerant of cold. The temperature in this fishpond is wrong; it's too high. The water has been heated by a heating device. There's something wrong!"

Li Mubo immediately turned around and moved closer to Lao Zhou.

When Lao Zhou saw Detective Li Mubo approaching, he didn't care about anything else and ran away.
