I am a super cop

Chapter 3018 The dust has settled
As the publicity campaign progressed, many passersby who were walking past the entrance of the community became curious about what was happening in the community.

Many passersby stop and discuss the matter at the entrance of the residential area.

Because Gu Chen brought sincerity this time, in order to get the people to cooperate with the evacuation on a rainy day, Gu Chen could only sincerely explain and promote the message here.

However, some elderly people remained unmoved.

In their own words, they're all getting old anyway, so the worst that can happen is they just die in their house.

This was quite a blow to Gu Chen's team.

After the elderly women left, Yuan Shasha complained, "Why are those people so stubborn? We were just thinking of them."

"They just don't want to make a fuss," Officer Wang said indifferently, arms crossed.

Seeing this, Lu Weiwei asked Officer Wang, "Old Wang, why aren't you paying attention?"

“How could I not care? I’m trying to find a solution,” Officer Wang retorted.

"You think you can come up with a solution? What solution could you possibly come up with?" Seeing Lu Weiwei's response, Officer Wang sneered, then said smugly:
“I often encounter those stubborn old men and women. To get them to cooperate, we have to make them feel that we are helping them and that they can also benefit from us.”

"Uh..." After hearing what Officer Wang said, Lu Weiwei thought for a moment and said:
"Old Wang, what are you talking about? Do you have any solutions?"

"Yes, of course there is a way," Officer Wang replied without further ado.

"Then hurry up and say it! What time is it? Why are you still pretending to be deep?"

"Tsk!" Upon hearing Lu Weiwei's comment, Officer Wang also clicked his tongue and retorted, "How am I pretending to be profound? Isn't this a method I just came up with?"

"Senior Brother Wang, just tell us if you have any ideas," Gu Chen said, offering a suggestion.

Officer Wang nodded silently, crossed his left arm over his chest, and gestured with his right hand, saying, "Getting them to cooperate isn't difficult. We just need to buy some eggs and get them to sign their consent."

"Get eggs?" Lu Weiwei laughed in exasperation upon hearing this, "Old Wang, is this method reliable?"

"Tsk, you don't believe me. I've already said this method is reliable. As long as you let these elderly people taste the benefits, they will be 100% willing to cooperate."

“They are actually willing to cooperate, but they will complain a few times. But you also do gas testing on their houses and give them eggs. Wouldn’t the old ladies and gentlemen be overjoyed? That’s what they like.”

"Haha." Yuan Shasha couldn't help but retort after hearing Officer Wang's explanation:

"Senior Brother Wang, you're more down-to-earth. Now that you mention it, giving out eggs seems like a good option."

Turning to look at Gu Chen, Yuan Shasha said, "Senior Brother Gu, what do you think?"

"It's feasible." Gu Chen said without further ado.

"Then it's settled. I'll call Director Zhao and ask him to approve the funds for purchasing eggs. If he agrees, I'll arrange for someone to go and make the purchase."

"Sure, then I'll have to trouble you, Senior Brother Wang." Seeing how helpful Officer Wang was, Gu Chen readily agreed.

Officer Wang was also quite efficient. After obtaining Zhao Guozhi's funding approval, he called his friend and asked him to help buy eggs at the market.

After completing all the operations, he placed the spreadsheet on the table and explained to everyone, "Just watch and see how I work."

An hour later, a three-wheeled motorcycle arrived at the entrance of the residential area, carrying a load of fresh eggs.

Officer Wang instructed everyone to help unload the eggs and move them behind the table.

They then started advertising at the entrance, offering things like signing up to receive eggs.

Basically, after you sign your name on the form agreeing to the transfer, you can receive a few eggs.

In no time, the elderly ladies in the neighborhood gathered around, all vying to sign in and receive their eggs.

Gu Chen, Lu Weiwei, and Yuan Shasha stood aside, watching this scene, and couldn't help but sigh.

"This Senior Brother Wang really has a knack for it," Yuan Shasha couldn't help but remark.

Lu Weiwei chuckled and said, "He just has a lot of crooked ideas."

“But Senior Brother Wang’s method is quite effective,” Gu Chen couldn’t help but say.

Lu Weiwei waved her hand and said, "Oh well, never mind. As long as we can get this job done, who cares if it's a white cat or a black cat? Let's go help."

Everyone helped distribute the eggs, and soon the signature column on the form was filled with writing.

……

……

The heavy rain arrived as expected, and with the help of Gu Chen's team and community volunteers, all the residents in the community were once again transferred to the gymnasium.

This time, it will also be a major test for Gu Chen.

Holding an umbrella, Zhao Guozhi arrived at the police line at the entrance of the residential area and looked at Gu Chen, asking, "What are the conditions like now?"

“Not bad.” Gu Chen nodded silently, and then added without further ado, “The weather is similar to that on the day of the incident.”

"I hope this experiment will be successful, otherwise it will be difficult to have another one," Zhao Guozhi said with a sigh.

Gu Chen knew that Zhao Guozhi was under immense pressure at this moment, so he quickly expressed his support to Zhao Guozhi:

"Don't worry, Director Zhao, this time I won't let you down."

"Alright." Seeing that Gu Chen's attitude was as firm as last time, Zhao Guozhi glanced at his watch and said, "It's exactly on the hour now, let's begin."

"Okay." Just like last time, Gu Chen dialed the phone number of the police officer on duty in the bathroom boiler room again to indicate that the experiment could begin.

Afterwards, Zhao Guozhi left. Gu Chen handed over the gate of the residential area to the police officers and then led his team members to the lobby of the bathroom.

At this moment, the bathhouse owner was still sitting on the sofa, this time with some peanuts in front of him and several cans of beer next to him.

Seeing Gu Chen and his group enter, he said irritably, "Officer Gu, when are you going to stop this nonsense? I've already said this has nothing to do with me, so why are you always picking on me? What did I do to offend you?"

"Please don't misunderstand." Seeing the bathhouse owner's strong resentment, Gu Chen didn't waste any more words and said directly:

"If this experiment also fails to produce results, we will still provide you with financial compensation."

"Fine, fine, fine." Seeing that Gu Chen had said so, and considering that this was the order from above, the bathhouse owner had no choice but to wave his hand to express his dissatisfaction.

Gu Chen then led everyone back to the boiler room.

At that very moment, the boiler worker was also continuing his work.

Gu Chen walked up to him and asked, "Is this batch of coal the same batch used on the day of the incident?" "Yes." Seeing Gu Chen ask, the boiler operator quickly replied, "The quality of the coal we receive each time is slightly different."

After a pause, the boiler operator pointed to the left and said, "This is the coal we used the other day."

As the coal continued to fall, the boiler operator pointed to the right and said, "This is coal that was just delivered."

“Burning different batches of coal produces different gases. Anyway, this time, I used the coal that was used on the day the murder occurred in the community, as you requested.”

"Okay, then you can continue." Seeing the boiler operator's response, Gu Chen didn't ask any more questions.

Standing in front of the sewer pipe, Gu Chen looked at the exhaust pipe leading to it, feeling a mix of emotions.

This might be his last chance. If he still can't get a result this time, then Gu Chen feels that he's almost out of options.

But Gu Chen was investigating with a rigorous attitude, and all the steps seemed to have become fragmented in this community.

The bathroom's boiler room and the residential area where the accident occurred seem to be connected only by the drainage pipes.

If these two deaths were not suicides, then they must have been caused by external factors.

Gu Chen has thoroughly investigated this residential area and has identified his ultimate target: the bathroom boiler room.

Now everything depends on the outcome. Once the outcome is in, Gu Chen will be able to connect all his previous judgments.

Then the case can be fully revitalized.

Gu Chen took a deep breath and could only wait quietly for the result.

……

……

A day later, when everyone arrived at the entrance of the community at the same time as before, 24 hours had passed.

This time, Zhao Guozhi also arrived at Gu Chen's side early.

Seeing Gu Chen looking down at his watch, Zhao Guozhi reminded him, "Go ahead and do it. If it still doesn't work, I'll take responsibility."

“Director Zhao, it was my idea to conduct experiments in the community. If any problems arise, I, Gu Chen, will take responsibility. You have already provided me with so much support.”

“Silly child, I’m your supervisor. It’s only right for a supervisor to take responsibility. Besides, how do you know it won’t work this time? I think it will work. Go ahead and do the testing. I’ll wait for your results here.”

"Okay." Seeing that Zhao Guozhi had said so, everyone felt there was no reason not to continue.

Following the previous arrangement, different groups went to different apartment buildings to test for carbon monoxide.

Gu Chen, along with Lu Weiwei, Officer Wang, and Yuan Shasha, still arrived at the apartment building where the incident occurred.

Following the prior preparations, everyone put on their gas masks, began using the keys to open the gate, and went inside.

This time, the data from the instruments everyone had was clearly different from the last time.

When everyone saw the numbers, their tense nerves were finally able to relax.

“Junior Brother Gu, your guess is correct. The problem lies in that bathroom. The carbon monoxide concentration here has reached 0.4%, which exceeds the 0.32% threshold for causing death. We are not mistaken.”

Lu Weiwei was incredibly excited when she saw the numbers.

Officer Wang couldn't help but sigh, "It seems we were on the right track in our investigation."

"Senior Brother Gu, you're truly remarkable! The poisoning of these people was caused by the improper ventilation in the bathroom," Yuan Shasha couldn't help but say.

At this moment, Gu Chen took a deep breath and looked at everyone through his gas mask. Gu Chen smiled because this time, he had made the right bet.

"It seems we didn't make a mistake. Senior Sister Lu, Xiao Yuan, you two quickly write down this evidence. We still need to go to the sixth floor to take a look."

“Okay.” Lu Weiwei and Yuan Shasha echoed in unison.

After completing the testing on the first floor, everyone went to the sixth floor, where Pan Xu and He Lili died of poisoning.

At this moment, everyone remains serious and dares not be negligent in the slightest.

But as everyone expected, carbon monoxide was still detected in the kitchen at a concentration of 0.37%.

Lu Weiwei looked at Gu Chen excitedly and quickly said, "Junior Brother Gu, we succeeded! The carbon monoxide concentration in this place is 0.37%, which is already higher than the 0.32% that is lethal. We were right again."

"Phew." Gu Chen felt completely relieved the moment he heard Lu Weiwei announce the numbers.

At this moment, Yuan Shasha asked curiously, "But why is it that only Pan Xu and He Lili on the sixth floor, and the man on the first floor, died of carbon monoxide poisoning in this building?"

"I remember there were residents living on the second to fifth floors at the time, so why were they unharmed?"

"Does this mean that carbon monoxide emissions can be blocked in these residents' homes?"

Hearing Yuan Shasha say this, Gu Chen also began to think, and slowly said:

"In the boiler room of the bathroom, the gas produced by burning coal is discharged through the sewer. Generally speaking, it will not enter the room because the bottom of the sewer pipe is designed with a bend."

"In this way, the sewage in the sewer pipes will block the emission of gas and also block various odors in the sewer pipes."

“That’s right.” Officer Wang echoed Gu Chen’s words.

"Modern sewer pipes are designed with a bend at the bottom, and toilets are the best example of this."

"Without this bend design, the toilet would smell terrible. With the bend design, the sewage stored inside can be effectively blocked from harmful gases below."

At this point, Officer Wang's eyes lit up, and he turned to look at Gu Chen, saying:
"So, the drain pipe on the sixth floor doesn't have a bend design?"

"No." Upon hearing Officer Wang's explanation, Gu Chen quickly denied it as well: "I checked it before, and the structure here does indeed have a bend design. It would be impossible not to have a bend design."

"How did these huge amounts of carbon monoxide gas get into the room through the drainpipe?" Lu Weiwei was also completely baffled.

Soon, Gu Chen seemed to realize something. He turned to look at the dining table and slowly said:
"Does anyone remember the takeout we had on the table back then?"

"Of course I remember," Lu Weiwei quickly echoed, and slowly added, "At that time, the takeout food on the table was still unopened, and neither of us had finished eating."

“That’s right.” Gu Chen nodded silently, then asked, “Do you remember when we first came here and knocked on the door, there was no response, so we ran to the restaurants outside and went door to door looking for someone who knew Pan Xu?”

"Of course I remember. It was a restaurant owner who told us that Pan Xu was a regular customer there, and every time he went, he would only eat stir-fried pork with chili over rice," Yuan Shasha quickly replied.

"That's right." Gu Chen breathed a sigh of relief after hearing this.
