Outside the city are wild, but there is a transition. There are abandoned buildings in the suburbs, and the outside is wilderness.

Since the great changes a thousand years ago, all kinds of creatures have entered a cruel state. They seem to be more suitable for such a world than human beings, but they have less wisdom than human beings. Humans also have powerful warriors, but they can only block the high-level explosive beasts out. If they are not close to the wilderness on the edge of the city, some small explosive beasts cannot be completely removed.

For example, now, there is a mouse staring at Rocco.

This is the only explosive beast in the abandoned blocks on the edge of the city. Although it can be called explosive beast, it has little lethality.

But when people don't pay attention, they also have the ability to take people's lives. Therefore, these abandoned houses on the edge have become isolation belts, and people are sent here to remove all small explosive animals. People are really not afraid of these mice when they are on guard, but if they are allowed to enter the urban area, no one can live in peace. Mice can drill everywhere.

Luo doesn't care. He's not here to kill rats.

He called Miao Xiaoduo: "I can't go back in time tonight. Cook by yourself."

"Luo Xiaoke, if you don't go home at night, it's more and more outrageous."

"Don't talk nonsense. There's some leftover food. You can eat it yourself. Don't wait for me."

Then he hung up the phone. Rocco found that the mouse was still looking at himself.

It suddenly occurred to me that if I could understand the knowledge of zoology, it would be very useful to deal with explosive animals.

Explosive beasts can be very powerful, but their wisdom is not high. They all have their own habits and weaknesses, and some can even be used.

In fact, even without aura, people have never been better than beasts, but humans have always dealt with them by understanding their habits. After understanding their habits, you can set a simple trap to catch more powerful beasts.

Rocco thought about it and opened the screen on his watch to search for e-books.

He wants to try whether this can make the system detect disciplines and search with the keyword "explosive beast".

Immediately, the system responded: "basic explosive beast knowledge is detected. Do you want to enter it?"

"Input!" Luo Ke looked at the system excitedly.

This is similar to criminal investigation. He tried to rise to the advanced level. It should be no problem to deal with the explosive animals around the city.

Explosive rats are small in size and weak in danger. They are a species alienated by aura and have natural enemies.

Extreme temperament, sometimes tyrannical, sometimes timid, people must be on guard when they encounter it.

Knowing this, Rocco stepped forward and shouted, "ha!"

The blaster screamed and ran away. It was still very smart. It knew it was not an opponent and ran very decisively.

Rocco began to identify the trace of the kidnapper for a long time. It was very difficult to identify, and the speed would be very slow. In addition, it was getting darker and darker now, and Rocco's search was becoming more and more difficult.

Will the man hide in these houses in the isolation belt?

It should not be. These houses can be searched by the police. Therefore, there is a danger of being detected at any time when hiding in the empty house. If you want to be completely safe, you have to go out of the field. The police will not search the outside area. It is too vast and dangerous.

But if you go out again, there are not only explosive animals, but also many dangerous elements wandering.

Like this hostage taker, he knows where to hide, and other more dangerous people naturally know.

High level warriors are only responsible for driving away powerful explosive beasts. It's a matter of sending people to ignore these dangerous elements.

Rocco decided to continue to go out, out of this isolation zone, is the three no matter area.

Another popcorn was scared away when he saw Rocco. It seems that they show more timidity.

Walking, Rocco felt something wrong.

Although it's not daytime, the city lights are reflected. Rocco can see it far away. What's the darkness on the road ahead?

With doubts, he walked in and looked again. Suddenly, it was creepy. It was a group of explosive rats!

A single one, they are very timid, but if there is a group, they will be very tyrannical.

The chirping voice made Rocco uncomfortable. He began to stop and consider where to go around.

He knows martial arts, but there are so many explosive rats coming from all directions. It's no use killing a few at once.

The explosive rats began to become bloodthirsty and showed sharp teeth to Luo Ke one by one.

Luo Ke stepped back slowly first. Unexpectedly, suddenly, the exploding rat burst open the pot and rushed towards Luo Ke collectively.

It's really unlucky. Even if so many explosive rats can be killed, they will be disgusting for a long time

Rocco ran back to see if there were any forks around. The rats were very big. They made a bang bang sound when running. The bigger one was the pig!

But at this time, a voice came out softly: "meow."

All the footsteps stopped. Rocco looked back. It was a little black cat, but it was only as big as a fist.

It's so small that the popcorn can eat it in one bite.

However, he found a kitten and ran to the middle of the road to sit down. None of the huge explosive rats dared to move!

There are natural enemies!

Rocco remembered that this is the fear left in the genetic memory, but is it really OK for such a small one? Even the cry is light, there is no sense of power, only those eyes are shining with strange light.

However, the rats retreated, and their natural fear made them fear this little spot and run away without a trace in an instant.

"There are cats?" Rocco woke up.

The cat is hard to see now. After a thousand years of changes, the cat began to mutate into a variety of creatures, and its body size has become huge. There is a kind of leopard called explosive beaver, whose body size is close to that of the ancient leopard.

Since then, the cat is a thing left in history. People can only understand it through images and words.

Rocco looked at the black cat suspiciously. It's so small. Should it be a cat?

The black cat came up and rubbed around Rocco's feet, which didn't show aggression.

So Rocco picked it up. It was a light one. The black cat showed obedience. Such a docile animal seemed to be the legendary rare animal, the cat.

"Unfortunately, no small animals are allowed in the city. They are regarded as dangerous goods and need a certificate."

Luo Ke regretfully put down the cat and applied for a certificate to keep a pet. It's very strict and you have to have an identity.

The stronger the martial arts, the more relaxed the conditions for keeping pets, because you prove that you have the ability to deal with them.

"Thank you."

Rocco put down the cat and went on, but the cat was still following. He didn't care so much.

Suddenly, Rocco found a button on the ground. It was an ornament on Xintian's clothes. It seemed that it was in the right direction. It either fell inadvertently or was deliberately pulled down by Xintian as a clue.

Rocco squatted down to check the button. The black cat caught up and smelled it with his nose.

"Can you smell like a dog?" Rocco shook his head.
