The giant mouse's eyes were blood red, looking at the mutant mice dragging rotting corpses. The mutant mice seemed to be very afraid of the giant mouse, lying on the ground and squeaking.

The giant rat smashed the rotten corpse into pieces with its sharp claws, then grabbed the rotten head, bit it, and waved its hands impatiently. The mutant mice dragged the shredded corpse and continued to move forward. After chewing on the rotten head, he drilled back into his mouse hole to rest.

The Shadow Crow flew forward quietly, but the giant mouse suddenly came out, and the sharp claws slashed directly on the Shadow Crow, splitting the Shadow Crow into several halves and quickly dissipating.

The giant mouse looked at the dissipated Shadow Crow with a puzzled expression on its face. After a few seconds, it panicked and ran towards the depths of the small waterway.

"Damn, it was discovered." Simon's face was ugly, and he never thought that in the dark night, Shadow Crow would be discovered by a mutant mouse.

"What's the matter?" Winnie asked.

"Those mutant mice are in the underground sewers." Simon said solemnly.

"Now what?"

"There are a lot of mutant mice in the sewers. There must be a leader-level mutant mouse. Let's go down and see the situation. If it's dangerous, we'll just quit." Simon said solemnly.

"Okay." The two nodded and agreed.

The three quickly ran to the garbage dump where the mutant mice had entered the sewers. Simon released the shadow ghost, and the shadow ghost easily opened the garbage dump, revealing a hole in the ground.

The shadow ghost went down first, and after confirming that there was no danger, the three of them descended into the foul-smelling sewer one by one.

Winnie and Marvin took out dim flashlights in their hands. The lights were not very bright, but they could barely see people.

"Damn, this sewer is almost full of garbage." Marvin said speechlessly.

"Don't talk, have you forgotten the rules of the investigation mission?" Winnie reprimanded.

The shadow ghost opened the way in front, and the three followed closely and moved forward quickly.

"There is movement, Marvin, eight o'clock on the left." Winnie said softly.

Marvin looked over immediately, a mutant mouse was looking at it, and the invisible thread directly shot through the mutant mouse's eyes, and also pierced into the brain, killing it directly.

"Three o'clock on the right."

"Eleven o'clock on the left, four o'clock on the right..."

Along the way, he encountered a lot of mutant mice, all of which were caught by Winnie and then killed by Marvin.

Simon is happy and leisurely.

The three of them walked along the sewer for almost 20 minutes. Except for some mutant mice, no other mutant mice were found, and the giant mouse disappeared. The huge rat hole was pitch-dark, and I didn't know where it led.

They had no choice but to keep moving forward, look, and finally reached the end of this sewer, and then entered another sewer. They walked in the sewer for almost two hours, but they found nothing.

Are those mutant mice gone?

Certainly not disappearing, they are hiding.

But where is it hiding?

Those ordinary mutant mice are easy to hide, but how can those giant mutant mice hide? Did he escape?

The three of Simon were puzzled.

"No, there are obviously a lot fewer mouse holes here." Simon recalled the mouse holes in the walls of the sewer along the way, and found the problem.

"There were a lot of rat holes in the sewer we came down from. After that sewer, the number of rat holes started to decrease."

"What does this show? It can only be said that the mutant mice are more active." Marvin spread his hands and said.

Simon was stunned for a moment, then shrugged: "It really doesn't explain what the problem is?"

"Someone came to investigate before the ninth inning, and no problem was found, so it was handed over to us." Winnie said.

"The mutant mice are looking for food in the garbage mountain. There must be a gathering place. If you can check all these mouse holes, you may find some problems." Marvin sighed.

Simon's eyes lit up and clapped his hands: "Yes, there must be one or several of these mouse holes leading to the gathering place of mutant mice."

"I know too. The key is how to check. The mouse hole is so big that people can't get in. Is it possible that they can't dig one by one?" Ma Wen said helplessly.

"You can't do it, I have a way. Although this method is a bit stupid, it's really the only good way in the current situation where I have no clue."

"What can you do?" Both of them looked at Simon.

Simon decided to use the Shadow Crow, which was just the right size to enter the mouse hole.

"Look at it."

"Let's start from here." Simon's spirit gathered, black light surged, and a small shadow crow condensed.

"What is this." Marvin looked surprised.

"Good stuff." Simon didn't explain much, he controlled the Shadow Crow, and the Shadow Crow flapped its wings and burrowed into a mouse hole and walked towards the mouse hole.

"Now I need to concentrate, you watch me." Simon said sternly.

"Don't worry, I will never let a mutant mouse approach." Winnie said sternly.

"My invisible threads form a cobweb, which blocks up, down, left, and right. There will be absolutely no problem." Marvin patted his chest and assured.

Simon concentrates on controlling the Shadow Crow and walks in the mouse hole.

At the end of this mouse hole is the garbage mountain above. Shadow Crow quickly returned, and then entered the next mouse hole.

Just checking one by one like this~lightnovelpub.net~ This is a tedious job, and some mouse holes are still very long. Entering and returning one by one is a waste of time.

But there is no way, this is the best way to find out the whereabouts of the mutant mice.

After spending three hours with nothing, they returned to the mouse hole they had come down from earlier.

There are many rat holes here, and it is even more troublesome to check.

These rat holes lead to everywhere in the garbage mountain, and there is no abnormal place.

After checking half of the mouse holes, I finally found a different mouse hole.

This rat hole does not lead to the top, but is horizontal. The rat road in the rat hole twists and turns, sometimes left, and now right, there is a kind of eighteen bends in the mountain.

It seems to be set up like this on purpose, so that no one can get close.

After 100 meters deep into the mouse hole, he found a mutant mouse blocking the front of the mouse, as if it was blocking the wind.

Simon felt more and more that there must be a universe in this mouse hole.

But how can we bypass this mutant mouse?

Simon fell into deep thought, and finally decided to try to see if he could avoid the mutant mouse.

Simon transformed the Shadow Crow into a mass of black shadows that moved against the wall of the mouse hole, moving very slowly, for fear of being noticed.

The closer the Shadow Crow got to the mutant mouse, the more nervous Simon felt in his heart. Fortunately, the mutant mouse's senses were not very keen, so he couldn't detect the moving shadow.
