"Hahaha! You!" Minister Li pointed at Sun Zhengguo and burst into laughter, then looked at Engineer Zhang.

"Comrade Zhang Qing, you heard what Comrade Zheng Guo said just now. I'd like to hear your opinion?"

“Minister Li, I think Director Sun’s method is excellent. The capable rise and the mediocre fall, which eliminates those who just come to coast along. I fully support it and have no objections.”

"Um!"

"Since everyone agrees, the ministry will definitely give it our full support." Minister Li nodded with a smile.

The three then discussed some specific matters, and Minister Li called over Secretary Wang.

Ask him to draft a document to be sent to each branch factory, so that each factory can select one or two outstanding technicians to report to the research institute after the New Year.

After finalizing the details of the technician training, Sun Zhengguo didn't linger and returned to the research institute to begin making arrangements...

In the afternoon, not long after starting work, Xu Damao rode his bicycle back to the steel rolling mill with a full load of goods, ready to return the projector.

After returning the projector, as was customary, Xu Damao gave the section chief and deputy section chief some local specialties before heading home to rest.

However, to his surprise, he was stopped by Yi Zhonghai as soon as he left the propaganda department.

"Hey! Uncle Yi, what's up? Need something from me?"

Xu Damao didn't seem to realize anything was wrong and continued laughing and joking.

Seeing Xu Damao's nonchalant attitude, Yi Zhonghai was furious, so his tone was accusatory.

"Da Mao, let me ask you, have you noticed anything unusual in the Liu family's corridor lately?"

Xu Damao was equally bewildered by Yi Zhonghai's question.

This statement is vague and incoherent; what does it actually mean?

"No, Uncle Yi, please explain yourself clearly. Why would I go to the Liu family's corridor for no reason? Is there gold or money there?"

When Xu Damao mentioned gold, a cold glint flashed in Yi Zhonghai's eyes, but he quickly put on a smiling face again.

"No, no, Da Mao, don't misunderstand. I recently lost something, but when I found it, all that was left was a box, so I wanted to ask if you had any clues?"

"Oh! Really? Then you'd better watch out! I lost a month's salary a while ago! I guess I'm never going to get it back!"

While Xu Damao was speaking, Yi Zhonghai kept observing his expression but did not notice anything unusual.

At the same time, Yi Zhonghai knew in his heart that he had definitely lost his mind today, and that if he continued to investigate in this way, something bad would happen sooner or later.

So, in order to dispel Xu Damao's doubts, he could only force a smile.

"Da Mao, the way I asked you the question just now was a little off. Please don't take it to heart. Also, please keep it a secret for me, otherwise it will be even harder to find the item."

"Don't worry, Uncle Yi, you know me, there will absolutely be no third person who knows about this."

"If there's nothing else, I'll head back first. After all, I've been watching movies all night and riding such a long way; I'm a bit tired and want to get home and rest as soon as possible."

"Of course, of course, then slow down."

After Xu Damao left, Yi Zhonghai stood there thinking for a while, but he still had no clue, so he could only return to the workshop.

Yi Zhonghai was unaware that the scene that had just occurred, including what happened next to the toilet that morning, had already been discovered by the undercover investigators.

Police officer Xiao Li had been keeping an eye on Yi Zhonghai for several days. Apart from the fact that he didn't know about the secret rendezvous with Qin Huairu in the middle of the night, he had also found out quite a bit of information about the other things.

The most important point is that Yi Zhonghai borrowed 100 yuan from Master Ma.

Think about it, Yi Zhonghai is an eighth-grade worker and he doesn't lack money, so why would he need to borrow money?

With many questions in mind, Xiao Li instructed another investigator to keep a close eye on Yi Zhonghai, then he hopped on his bicycle and hurried back to the police station…

In Captain Zhang's office at the police station, another investigator, Xiao Zhang, was reporting on the situation while holding a stack of documents.

"Captain Zhang, I've gone through a lot of trouble to find the historical records of a few people. Could you please take a look?"

"Oh! Let me see."

Captain Zhang then flipped through the files. The first page contained information on He Daqing, who was the easiest to find because of his past imprisonment.

But since his release from prison, He Daqing has been extremely well-behaved. Apart from doing odd jobs and cooking, he hasn't done anything else.

The second page contained the deaf old lady's information, and Captain Zhang's eyes lit up after reading it.

According to the information, this old lady used to be the concubine of the Beiyang Army's commander.

Although her husband later died and she escaped, is it possible that she took a large amount of gold and silver with her when she fled...?

Then, Captain Zhang turned to the third page of the document and unexpectedly found something of great value.

This third page contains information about Yi Zhonghai, but there's not much about him personally.

But the key issue is that his father, Yi Buqun, was once a servant of the deaf old lady, and the two of them fled to Beijing together.

Now that everything is connected, here's the question!

Is it possible that Yi Zhonghai learned from his father that the deaf old lady had a large sum of money?

The murder was committed in order to obtain this huge sum of money.

After reviewing the information, Captain Zhang made his decision and immediately gave the order.

"Xiao Zhang, don't worry about He Daqing anymore, focus all your efforts on investigating Yi Zhonghai."

"Yes, Captain Zhang."

Upon receiving the order, Xiao Zhang saluted and prepared to go out to carry out the task.

Just then, Xiao Li, who had returned from the steel rolling mill to report the situation, walked in from outside the door.

"Team Leader Zhang, we've noticed that Yi Zhonghai acted a bit strangely today. Here are our investigation and records from this period. Please take a look."

"Hmm~! Well done."

Captain Zhang didn't expect that just as they were about to investigate Yi Zhonghai, Xiao Li brought new information.

"Xiao Zhang, don't go yet, listen to this together."

"Yes, Captain Zhang."

After giving instructions to Xiao Zhang, Captain Zhang began to look through the notebook.

As time went on, his smile grew wider and wider, and he couldn't help but slam his hand on the table and stand up.

"Xiao Li, you did a great job this time. I'm now absolutely certain that Yi Zhonghai is guilty of murder for money."

"Captain Zhang, could you tell us about it?"

Xiao Zhang was quite curious; he had just been asked to assist in the investigation of Yi Zhonghai, and now a conclusion had been reached.

What other unknown details are hidden behind this?

"Hmm! You two exchange information first, and it shouldn't be difficult to see the problem."

Xiao Li and Xiao Zhang exchanged a glance, and then handed over the information they had to each other.

After a short while, the two finished reviewing the information. Since Xiao Li was mainly responsible for investigating Yi Zhonghai, he spoke first.

"Captain Zhang, based on the information, Yi Zhonghai is indeed a prime suspect. I suggest we make an arrest."

After listening to Xiao Li's explanation, Captain Zhang did not express his opinion, but instead looked at Xiao Zhang.

Seeing this, Xiao Zhang also shared his opinion.

"Captain Zhang, I also suggest making an arrest, but it needs to be done secretly. If Yi Zhonghai doesn't confess, I think Qin Huairu might know something?"

"Oh!" Captain Zhang's eyes lit up. "Go on."
