Zheng Nanjun suddenly thought of a lot at this moment, and hurriedly explained to the poplar next to him.

Hu Yang hurriedly nodded and recorded it, the more evidence he could find, the more likely he was to catch them as soon as possible.

It's best to find people who are directly related to them, so that it will be easier to determine the evidence and catch them.

It's just a pity that Hu Yang feels that it may be difficult, because his opponent is He Huandong, this old fox is too shrewd, he will definitely cut off all the clues.

Even if you can't figure it out, those who did something to this place have already been killed.

With the ruthlessness of the Heaven and Earth Alliance, this is too possible.

The group cautiously advanced in the sewer, and not long after, under the leadership of Zheng Nanjun, they came to the bottom of the construction area and found the sewer area of the collapsed part.

The sewer ahead had collapsed, and it was no longer passable.

But the collapse here, Zheng Nanjun carefully searched, looking for traces of solvent.

This is to be expected, what they are looking for is a place to dilute the solution here, and the other party cannot dilute it on the ground and then bring tens of thousands of liters or even more of solvent down.

In the area around here, there are many spacious underground passages, all of which have room for diluting potions.

Zheng Nanjun looked at the traces of the water flow here and carefully considered the possible state of the water flow at that time.

When the accident happened here, it was already after heavy rain, the flood peak had passed, and the water here was not so big, but it was still enough for them to use to dilute the solvent.

"Based on the amount of water discharged in those days, the drainage height here should be about a meter deep. ”

"It's too high, they don't have the right place to do the dilution job. ”

"It's too low, the amount of water isn't enough, and their dilution can't be done by hand. ”

"They must have been diluted by some mechanical power and sprayed onto the buildings on the ground. ”

"Otherwise, it won't cover that much of a area. ”

Zheng Nanjun's brain is very awesome at this time, although he is not a master of solving cases, but he is familiar with the reaction time and required conditions of everything here.

As long as these conditions are met, it will be easier to find possible locations here.

"Moreover, in order to achieve that kind of efficiency, it is necessary to install high-power pumping machinery and jetting machinery on the ground, so there must be traces of the use of machinery here. ”

While analyzing, Zheng Nanjun took Populus euphratica and his party here to look for possible areas.

They searched as they walked, and after walking far, one of Zhong Di's subordinates suddenly shouted after looking at the water that was still flowing.

Then, at once, he pointed to a small iron fence.

Hu Yang immediately looked over and saw that something seemed to be blocking the fence.

"The eldest young master, it's a human, half a skeleton. The man said immediately.

Hu Yang's heart suddenly moved, half a skeleton?

Fortunately, Zhong Di was careful, and when he came, he actually brought a few long pole fishing nets, and several people immediately went over and stood aside, and quickly fished out the bones that were blocked by the fence and went to the shore.

Hu Yang saw this corpse very strangely, but half of the clothes could still be seen on the bones, and this half of the clothes was the work clothes here!

"It's the people of the port company. Zhong Di said immediately.

However, Zhong Di then smiled bitterly, "Young Master, I have a hunch that this person may be the one who came to sabotage, and then, he was killed. ”

Hu Yang nodded slightly, this is the normal operation of the Heaven and Earth Alliance.

"Arrange for two people to deliver ...... Forget it, without Zheng Gong with him, it is estimated that he will get lost. ”

"Leave two people watching, and when we go up, we will walk together, take them up for a DNA test, and we should be able to find someone. ”

Zhong Di immediately pointed to two people to stay, these people are all bold and not afraid of this.

"It is estimated that the place where they concoct the potion will not be too far away. ”

Zheng Nanjun didn't have any fear at the moment, and all his thoughts were on finding out the person who sabotaged his hard work.

This man seems to have been killed and rushed here with the current.

Zheng Nanjun looked at the flow of water here, and immediately led everyone back, walked to a branch line, turned in, walked a few steps, and stopped.

Although some places on the ground have been destroyed by the current, they ...... Traces of corrosion remain here.

There is no doubt that the traces of corrosion were accidentally spilled by them when they were diluting the potion here.

There was a large piece of the maintenance passage on one side, and by the way, a large piece of the wall was corroded.

Zheng Nanjun looked here, looked a little on the ground next to him, and found a few places where the expansion screws were punched and fixed.

He could make sure it was a place where the pump was installed.

They must have been diluted here, pumped to the ground, and then sprayed inside.

As soon as Hu Yang waved his hand, several people immediately dispersed and searched around.

"Zheng Gong, but that thing is so domineering, can this pipe hold up?"

Zheng Nanjun shook his head slightly, "It doesn't corrode plastics, this is the magic of chemicals." ”

"They just need plastic to keep it from corroding, and there's a lot of hose to choose from. ”

"Even if it's a water pump, there is a kind of anti-corrosion made of high-strength plastic, and it is not difficult for them to do this kind of thing with all their hearts and minds, and find something that prevents corrosion. ”

Hu Yang nodded immediately, and not long after, Zhong Di and a few people climbed into a small branch pipe leading to the ground, where the protective fence was demolished.

Climbing in from here, it didn't take long for Zhong Di to reach a place where there was only a manhole cover from the ground.

This sewer manhole cover is hidden from the ground up, underneath a collapsed shed.

Zhong Di quietly opened a gap and looked up, this shed was temporarily used for construction and accommodation for workers.

Only by this moment the workers had already evacuated, leaving only empty crooked beds and the like.

And the manhole cover for this sewer is located under the bed in one of the corners.

The first half of the shed was the collapsed part, and only a tiny part remained uncollapsed.

Zhong Di quietly put the manhole cover and came back and found Populus euphratica, "There is no trace, but we went up from this place, and we can just see the collapsed part, which is less than fifty meters away from the position of the collapsed main beam." ”

Zheng Nanjun looked at this branch passage, climbed in to take a look, and when he came back, he nodded slightly, "This is it, they sent the solvent up from here." ”

"Bringing the solvent up from here, you're almost there. ”

"Now we just need to make sure that on the day they do it, there are no workers in the shed to know the details. ”

Hu Yang shook his head slightly, "After the investigation, on the day of the start, it was the workers who collectively paid their wages, and they held a mobilization meeting for all employees. ”

"So, when they started, there happened to be no one here. ”

"This is what they have planned for a long time. ”

"Now, even if we find traces, I'm afraid there is no way to identify them, after all, what we want is to bring down Hu Zhentian and them. ”

Zhong Di said in a low voice: "Then we can only try to see the person who only has bones left." ”
