Yaldron City, sewer.

Lei Yi has been to the sewers of many cities, and has also been to the depths of the underground in Roland and other cities in the Western world.

He made holes and drilled through cracks. In order to blow up Roland's Western fortress, he even dug mountains like a miner.

Once, he thought that the sewers of the Holy Church Kingdom were the largest and most perfect, and the most artistic and beautiful design.

But after seeing the city of Yardelon, he felt that the sewer of the Holy Church Kingdom was just a slightly cleaner but ordinary drainage facility.

The sewer in Yaldron City can really be described as well as all-in-one, and there are signs in every area.

Now, Lei Yi is in the "sewage treatment area", and there are three places where "water accumulation", "filtration" and "purification".

The wastewater on the upper layer will be discharged into the water accumulation area through several thick pipes, and then passed through the filter area layer by layer, and then discharged into the purification area for the machine to be purified, forming a complete reuse cycle.

Such a sewage treatment area has been treated as many as hundreds of tons of sewage in just a few breaths.

There are several areas like this in the sewer.

Not only that, the countless pipes on the upper floor are arranged neatly like the precision wires arranged by electricians, making it feel comfortable to see the obsessive-compulsive disorder.

"Now I'm at the sewer, how do you want to get up?" Lei Yi was in the middle of thinking.

"Yeah!" Pangpang grabbed Lei Yi's hair, then pointed to the drainage pipe above and shouted.

"The source of wastewater must be connected to the city, but the impact of this water flow is so strong, are you sure we can get in?" Lei Yi looked up at the top, then shook his head, rejecting the proposal.

The wastewater discharge in the pipeline was amazing. Even if he had the seventh level of strength, he was confident that he could not resist this momentum.

Not to mention that he was going to climb up along the pipe with the water flow.

Shaking his head and dispelling this thought, Lei Yi continued to move forward in the sewer.

Finally, he discovered that to go from the source of wastewater, there is only one way to follow the pipeline.

"Fuck, there is no way!" After searching for a long time, he couldn't find the way up. He was desperate and even swearing.

"Hehe!" At this moment, the little fox fat man seemed to have discovered something, jumped down from his head and rushed forward.

Then, she stopped on a platform and called out.

Lei Yi hurriedly leaned over and then found that there was a map of the castle sewer area here, and it was carved on a metal plate.

"This is the wastewater treatment area. In front of it is a debris discharge port and a sewage discharge port. If it is sewage that cannot be processed, it turns out that it can be discharged to other places..."

He looked at the map and after watching for a moment, he recorded all the information here in his mind.

Suddenly, Lei Yi looked at the top of the sewer area as if he had discovered something. According to the direction of the map "up, north, and south", it should be the northernmost area.

There is actually a door mark on this part on the map.

Seeing this mark, Lei Yi knew that this was the exit he had been looking for.

"Good pony, let's go!" Lei Yi grabbed the little fox Pony pony from the ground, put it on his shoulder, grabbed the iron plate and pulled it up directly from the platform.

In this way, he has a map of the sewer and has no worries about not knowing the road.

One person and one fox, we move forward together again.

The only thing that made Lei Yi a little helpless was that the area was at the innermost part of the sewer, and not only needed to pass through the purification area of ​​the sewer, but also through the pollutant discharge area.

That is, those things that cannot be purified and discarded.

As soon as he stepped into this area, Lei Yi regretted it.

"Wow, this smell is too bad!" He covered his nose and mouth, feeling desperate.

Not only him, Pangpang couldn't bear it either, with tears in his eyes and disgust on his face.

"Pangpang, do you have any way..." Lei Yi asked, enduring the discomfort in his body.

The little fox ponytailed his chest with his claws, and finally took out a small silver pocket and threw it to Lei Yi.

Then her body shrank, turned into a white light, and flew into her pocket.

"This..." Lei Yi never expected that this girl would leave him outside alone, but she hid in her pocket and went to sleep.

Sure enough, the kind of owner there are the kind of pets you have.

The little fox Fat is the true legend of the deep night sky bell, highlighting a shameless one.

"Hmph, slander women!" Lei Yi complained, suppressed the disgust in his heart, took out a layer of cloth, and put it on his face as a mask, which made him feel better.

He stepped into the pollutant discharge area and felt muddy under his feet.

Resisting the discomfort in his heart, Lei Yi didn't even have the courage to look down, for fear that anyone would be unable to bear it and would vomit out the overnight meal.

This is a design similar to an air raid shelter, with a huge area and divided into rows of round arches.

In this space, there are piles of garbage everywhere, emitting a disgusting smell.

After moving forward for a while, Lei Yi heard a "squeaking" sound.

Needless to say, how could there be no mice in places like sewers?

But when Lei Yi walked across a corner and came to a space full of dark and muddy under his feet, he found that he was wrong.

Since there are huge crows and werewolfs in the woods outside the castle and ugly monster fish in the moat, how could there be only ordinary mice in the sewers in the castle?

What appeared in front of Lei Yi were mice that were bigger than pigs.

The two front teeth of these rats were as sharp as daggers, and their eyes were flashing with scarlet and fierce light. They were gathering in a garbage dump and searching for something.

One of the mice that were approaching seemed to have noticed it and sensed Lei Yi's breath.

Suddenly, within a few hundred meters nearby, all the mice knew that "eating" had appeared.

"Hey, hey, I'm not the 'rat-killer' of the castle, and the owner of this castle doesn't give me any money!" Lei Yi complained and ran wildly.

This time, what he wanted to avoid waswolves, but mice as big as pigs.

While running, he picked up the map and started running wildly in the pollutant emission area.

After running for more than ten minutes, Lei Yi saw a warning sign telling him that there was Area 2 of the pollutant emission area in front of him.

"Damn, this place is so big!"

Behind him, the rat group not only did not decrease, but on the contrary, it increased several times compared to before.

The number of rats chasing him has increased from dozens of rats to hundreds of them now.

And from all directions, all kinds of rats rush out from all places, all crisscrossing and crisscrossing places.

These mice are as big as piglets, and the largest ones are even comparable to giant wild boars going up the mountain.

It was the first time Lei Yi was chased by so many mice.

"No, if you escape, I don't know how many you will encounter, so you have to fight back!" Lei Yi ran away for half an hour again. Seeing that he had not left the pollutant emission area, he could only choose to stop and prepare for the battle.

He let out a wild roar, and a fierce aura erupted through his body, and he turned into a god, a ferocious ghost and god, and rushed into the group of rats.

In this first round of confrontation, Lei Yi relied on his fierce momentum to shock the rat group and launched a massacre.

But then, as the rat group died countless times, a large number of corpses and blood spread, and the smell of blood spread throughout the nearby areas.

The rat group seemed to be stimulated and began to become violent, and rushed towards Lei Yi as if he was desperate.

Not only that, their number has not decreased, but on the contrary has increased with support from all directions.

In addition, the dead bodies of rats were also eaten by them, becoming the food of other similar species.

Lei Yi killed hundreds of rats, and he was a little tired, but the group of rats from all directions remained in a steady stream.

It can be said that there must be at least tens of thousands of mice in this pollutant discharge area, and even this number may be more.

"My God, I can't kill them all. How many of these mice have given birth to here? Are there no natural enemies..."

Just as Lei Yi's words fell, the surrounding rats suddenly became awkward.

Although they were violent enough at the beginning, they were all killing Lei Yi.

And at this moment, a team of turning around appeared in the rat group.

Not only that, the number of this group of rats near Lei Yi was increasing, and almost all of them began to flee in the opposite direction, and many of them even stepped on their companions' bodies and ignored the food around them.

Hiss ~ Hiss ~

When Lei Yi heard this voice, his expression froze.

"Hey, hey, aren't you playing with me? I just asked if there were any natural enemies, and you appeared!" He turned around slowly, forcing himself not to move too much, so as not to attract attack.

When he turned around, he saw a giant python, which was as thick as a bucket and nearly ten meters long, swimming from not far away.

At this moment, there was a mouse struggling in the mouth of the giant python, but it was useless.

The giant python's mouth opened and closed, and the mouse was swallowed in its belly and then disappeared.

The giant python is very well reflected, and obviously a mouse cannot satisfy it.

Now, the rat group around has disappeared, and only Lei Yi is left here.

The giant python did not chase its prey, but stayed here. Why?

Don't think too much, someone already knows it.

In front of him, a bloody mouth appeared.

The giant python did not give Lei Yi time to react. Seeing that the prey had seen him, he immediately launched an attack.

The snake's attack speed was rapid. When it twisted its head and rushed, it carried a pungent fishy smell, like a poisonous dragon.

Seeing this, Lei Yi let out an roar and fought back at the same time.

One man and one snake immediately fought together.

The giant snake's body twisted and smashed around, making a loud roar.

The period was mixed with Lei Yi's roar, the sound of punching, and the explosion that the fist penetrated the flesh and blood.

A few minutes later, the battle finally ended.

Lei Yi grabbed a shriveled snake skin, and he had no luck at all after the war ended.
Chapter completed!
