The truth! Sneaking into the factory!

Lin Yuan nodded: "That's right!"

Hearing this answer, everyone present couldn't help but shiver; it was too terrifying.

They didn't even touch it, and they cleaned it immediately, but he still died?

How does that sound so eerie?

Lin Yuan knew they didn't believe him, so he calmly explained, "This kind of poison isn't like what we traditionally understand as being ingested; it's somewhat similar to radiation!"

"Once exposed, without proper protection, even if it doesn't enter the body, you can still be poisoned."

"Three months later, that scientist developed various poisoning symptoms, and after five months, a check-up showed that the mercury in his blood was over 4000 times that of a normal person."

"Not long after, he died!"

Hiss~~

Although everyone was mentally prepared, hearing the full outcome still made them gasp.

At this moment, Team Chen asked doubtfully, "How are you so sure that this is the poison inside? If it's so potent, why aren't the fish dead, and why haven't people had problems yet?"

Lin Yuan smiled and explained, "That's because there isn't much methylmercury in the water, and the Big Lake is very large, diluting a lot of it. What's truly poisonous is this mud!"

"Previously, it was already detected that these discharged wastewater contained a certain amount of mercury, which would precipitate in the mud after falling into the water."

"Under normal circumstances, it wouldn't lead to widespread pollution of the Big Lake or fish poisoning. However, this lake water is exceptionally rich in methanotrophic bacteria."

"When mercury comes into contact with methanotrophic bacteria in the mud, it undergoes methylation, converting into a large amount of methylmercury."

"When the riverbed sludge is stirred up for some reason, methylmercury can return from the bottom sediment to the water. Then, through the food chain, the concentration of methylmercury accumulated in fish and shellfish can be tens of millions of times higher than in the water body."

"Long-term consumption of such fish and shellfish can cause chronic methylmercury poisoning in humans."

"Moreover, methylmercury has high lipid solubility, a low boiling point, is volatile, and is easily absorbed through the digestive tract, respiratory tract, and skin."

"Once ingested into the body, it rapidly distributes to various tissues and organs throughout the body, but primarily accumulates in the cerebellum, cerebrum, liver, and joints."

"This is the truth behind the villagers' poisoning!"

After hearing Lin Yuan's explanation, everyone was stunned.

They looked at him as if he were a celestial being.

Netizens in the live broadcast room were also amazed by his actions, calling out "666."

--- [I'm absolutely shocked. How much does Lin Yuan know? Even I, someone who doesn't understand chemistry, understood it. Did he start learning in the womb?]

--- [It's too exaggerated. He's constantly refreshing my understanding. First, the fish were poisonous, and now you're telling me that the reason they're poisonous is related to the lake water itself. Who could have thought of that? I really don't know whether these villagers should be happy or sad. Because the bacteria made the water quality good, and then because of the bacteria, the village was almost wiped out.]

--- [What does this have to do with bacteria? Isn't the root of the problem wastewater discharge? If there were no wastewater, the bacteria would function correctly. Only with wastewater do chemical reactions occur, but I really didn't expect this outcome.]

--- [It's terrifying. The Factory probably never imagined that the wastewater they discharged would kill countless people. In their eyes, it might just be environmental pollution.]

After Lin Yuan's analysis, everyone understood that the root cause of the poisoning was this large water pipe.

Now, a new problem arose: where did this water pipe lead? The secret hidden behind it was intriguing.

To clarify the underlying reason, Team Chen immediately stated that they would continue forward to find the Factory discharging the sewage.

Everyone nodded in agreement and set off again.

At the same time, Director Yang arrived at the mountain village with his team and immediately arranged for a large number of Police Officers to completely seal off the Big Lake.

Accompanying medical personnel provided emergency treatment to the villagers on the spot.

Upon learning that Team Chen had gone upstream to search for clues, he immediately called to inquire about the situation.

When he heard that someone was discharging chemical wastewater into the lake upstream, he quickly led his team to catch up and help.

On Lin Yuan's side, because the area was too remote, they drove for several minutes and saw nothing but overgrown green belts everywhere.

They drove for a full ten minutes, and about 2 kilometers from the sewage outlet, they finally saw a Factory.

To avoid alerting them, the car stopped far away.

Team Chen looked at the distant Factory, lost in thought.

He wasn't sure if it was this Factory, as it was a bit far from the Big Lake, but it was the only Factory nearby, making it the prime suspect.

Secondly, even if he wanted to go in and search, he would have to report it in advance and prepare a search warrant.

But at the moment, time was tight, and the news of the villagers' poisoning would spread quickly.

At that time, the Factory discharging the sewage would also surely learn the news and destroy evidence.

This put him in a dilemma: if he investigated, it would be against the rules; if he didn't, he feared missing a crucial opportunity.

After some deliberation, he finally decided to secretly go in and investigate.

But then, other Police Officers poured cold water on his idea: "Team Chen, even if we sneak in, how will we find the Factory's sewage outlet? They can't possibly lead us there, can they?"

Hearing this, Team Chen immediately fell silent.

Yes, it wasn't as simple as just sneaking in; they needed to personally see the Factory's sewage outlet.

If they were indeed discharging sewage into the Big Lake, how could they easily let others see it?

But at this moment, Lin Yuan suddenly smiled and said, "I have a suggestion that might actually make them lead us in."

As soon as he said this, everyone's expressions changed, and their gazes all focused on Lin Yuan.

Team Chen quickly asked, "What method?"

Lin Yuan smiled and pointed to the accompanying doctor: "It's actually very simple. In a moment, we'll pretend to be Government public welfare medical examination staff and go in to help them with their check-ups."

"Workers in chemical factories deal with chemicals year-round, so they more or less have some underlying health issues. I believe no one would refuse a free medical examination, right?"

"At that time, we'll have the doctor go directly to the Factory's work area for the check-ups, and Team Chen and I will take the opportunity to look around. But Team Chen, you'll need to change your clothes."

Everyone's eyes lit up upon hearing this idea, and they instantly nodded in agreement, full of praise.

Team Chen even slapped his thigh, exclaiming excitedly, "This is a great suggestion! What are we waiting for? Only Lin Yuan, the doctor, and I will go in. The others will stay here and guard."

After a brief discussion, the group took their tools and walked towards the Factory gate.

Originally, they hadn't planned on bringing the Photographer, as an extra person meant extra risk.

However, considering that even if they went in and found evidence, if they couldn't photograph and record it, the Factory might deny it, and all their efforts would be in vain.

Two minutes later, the group arrived at the Factory gate.

The Factory was large and looked somewhat dilapidated, with several nameplates having fallen off the gate.

But from the remaining marks, the Factory's name, Sunset Chemical Factory, could still be seen.

Looking around, the Factory was filled with huge steel-structured workshops and several large cylindrical tanks, though it was unclear what was stored inside.

Standing at the gate, one could clearly smell a chemical odor, and the humming sound of machinery operating inside occasionally reached their ears.

Just as they were lost in thought, suddenly, the guard in the security booth at the gate shouted, "Hey! What are you doing?"

Hearing this, the group immediately snapped back to attention.

Lin Yuan smiled and stepped forward to greet him: "Master, we are a compassionate public welfare medical team sent by the Government, specifically responsible for providing free medical examinations to Factory employees throughout the city."

"Look, we've brought the doctor and our equipment. Please open the gate and let us in."

The guard heard this and carefully scrutinized the group. When he saw the doctor and the medical equipment in their hands, all his doubts immediately vanished.

He proactively walked out of the security booth and said with a smile, "That's great! I've been feeling dizzy and unwell lately. Can you help me get a check-up too?"

Immediately after, with a 'drip' sound, the retractable gate slowly opened.

Lin Yuan smiled and nodded: "No problem. But don't you need to stay here and guard the gate?"

The guard smiled and waved his hand: "No need. In this godforsaken place, only a few strangers come in a month."

"Alright then. Perfect, you can help lead the way to the dirtiest part of the Factory where people are working. We'll prioritize their check-ups. Of course, you're first."

"Alright! Alright! No problem, I'll take you there right away."

Led by the guard, the group swaggered into the Factory.

The others didn't say a word throughout, but they were already astonished.

They got in so easily?

And in such a large Factory, finding the sewage outlet would be incredibly difficult.

Just because of a few words from Lin Yuan, the guard personally led them there?

Before entering, each of them was incredibly nervous, even just facing the guard, their palms were sweating, fearing that someone would notice something amiss.

But it turned out to be this easy?

So, all that worry was just self-pity?

One could only say they didn't understand the workers in these factories.

Who among those who came to work here didn't have heavy burdens at home?

Who didn't know that chemical products could easily cause illness and shorten one's lifespan?

But they still chose to work here, not because they weren't afraid of death, but because they had no other choice.

Normally, they were reluctant to even buy medicine when sick, let alone go to the Hospital for a check-up.

Now, a doctor suddenly appeared, offering free medical examinations, which was like grasping at a lifeline.

And there was one most important factor: if the sewage in the Big Lake truly came from here, then the Factory's environment must be indescribable, and it was likely that the people working there had already developed some health issues.

It was evident from the guard's attitude; even he, a gatekeeper, was so afraid of death, let alone the workers inside.

After walking for a while, led by the guard, the group arrived at one of the large workshops.

The guard led the way, smiling and explaining, "This workshop is usually the dirtiest. The smell inside might be a bit unpleasant. If it's too much, I can call them out for the check-up outside?"

"No, no!" As soon as he finished speaking, Lin Yuan quickly waved his hand: "Let's just go straight in. We need to finish early to check others too."

"Right, right. Okay, I'll take you in."

The guard eagerly walked in front, and as soon as he entered, he shouted at the top of his lungs, "Everyone stop! The Government has sent doctors to give us free medical examinations! Come over, everyone!"

Whoosh~~

As soon as these words were spoken, the entire workshop instantly erupted.

Everyone looked over in unison, and those who reacted quickly ran off, fearing they would be too late to queue and miss the check-up.
