After leaving the activity room, Chen Chu went to the training classroom to practice swordsmanship and Dragon Elephant Kung Fu until the school bell rang after four o'clock.

Today he did not go to the reading room to read, but left school early.

After leaving the school gate, Chen Chu took a taxi to the flower, bird, fish and insect market.

It was still the same bird and insect pet shop. Chen Chu walked in and asked familiarly, "Boss Li, where are the insects I ordered?"

Seeing that it was an acquaintance, the boss smiled and said, "Here, I put them in a box, and I packed a few more for you in case they died on the way."

As he spoke, Boss Li took Chen Chu to a shelf inside, where there was a small box about 20 centimeters long and wide, with some rotten leaves spread inside.

On these leaves, four insects, about three centimeters in total, with long and narrow bodies and a metallic sheen on their surfaces, were crawling around.

The most special thing about these insects is their protruding compound eyes and unusually long six legs.

"This kind of bug is quite common, but it's hard to catch. Recently, creatures in the wild have become more and more aggressive, and many of them have slight mutations."

"Since we are all acquaintances, I will only charge you 400 this time."

"Okay, thank you, Boss Li."

Chen Chu didn't bargain and directly transferred four hundred yuan to him. He walked out of the pet store carrying the box and a box of mealworms given by Boss Li.

This is what Chen Chu prepared for the next evolution of the heavy armored beast.

This is a carnivorous insect called a tiger beetle.

What it is most famous for is its speed, which is known as the fastest in the insect world. It can move a distance three hundred times its body length in an instant.

After determining that the next evolutionary goal of the clone was to enhance speed, Chen Chu looked up a lot of relevant information and finally decided on the tiger beetle.

By then, after absorbing the tiger beetle's genes, not only will it instantly gain a movement speed three hundred times its body length, even if it's only ten times as fast, it will be a super enhancement for the heavy armored beast.

In fact, for the third evolution of his clone, Chen Chu had considered mutant beasts.

But ordinary mutant beasts are only strong and have strong defenses, and are not as powerful as today's heavily armored beasts of the same size.

And forget about those powerful mutant beasts with special abilities, as he can't afford to buy them or kill them now.

In addition, Chen Chu also considered some special creatures, such as tardigrades.

This thing, which is called a bug but is more like a microorganism, is known as an immortal creature. It has extremely terrifying vitality and can survive in extremely high and low temperatures and adapt to various environments.

Even if you go into outer space, you can survive through your special abilities.

But after carefully reading the biological data, Chen Chu gave up.

The so-called tenacious vitality of this creature and the reason it can survive for hundreds of years is actually a dehydrated dormant state used to avoid the environment.

This state is similar to suspended animation, where you can't do anything. If you encounter an enemy at this time, you can only wait to die.

However, its actual active life cycle is only a few weeks, so the claim that it is immortal is an exaggeration.

"Brother, you came back so early today."

After five o'clock, Chen Hu came back from school and was surprised to see Chen Chu already at home.

"Well, I had something to do today, so I left early."

Chen Chu called Chen Hu over and pointed at the box on the table: "Xiao Hu, remember to feed this to me after I go for the trial in a few days."

Chen Hu looked at the tiger beetle on the table curiously and asked, "Brother, what kind of bug is this?"

Chen Chu made up an excuse: "Tiger beetle, my new pet, I can just throw a few mealworms in there every day."

"No problem, bro."

According to the current growth rate of the Heavy Armored Beast, it is expected to reach the third evolution around the end of the month, and he may still be in Koroya at that time.

Therefore, Chen Chu decided to hand over the task of feeding tiger beetles to Chen Hu.

When the clone was about to evolve, he would call Chen Hu and ask him to go out at night and throw the box containing the tiger beetle into the river.

As for the reason, just find any one.

After arranging everything, Chen Hu took the initiative to cook. This kid has become more and more diligent recently. Seeing this, Chen Chu also took the tiger beetle upstairs to prepare for practice.

The actual situation was that I leaned back in the chair and my consciousness sank.

Suddenly, under the mud and sand of the surging river, a black lizard-like head rose up, looking extremely ferocious against the backdrop of three pairs of red horns.

The mud and sand rolled, and a heavily armored beast like a crocodile swam out from the bottom of the river.

During this period, almost regardless of day or night, as long as he felt that the heavy armored beast had almost digested the food, Chen Chu would distract himself and control it to continue eating.

However, this is an estuary with deep water and wide rivers, and there are some ferocious fish that can adapt to fresh water, such as mutant white sharks covered with scales and killer whales with horns on their heads.

When faced with mutant fish that are over eight meters in size, the heavy armored beasts will turn around and leave, or sink into the mud at the bottom of the river.

Without knowing the strength of these huge mutant fish, there is no need to fight them. If you get hurt, it will not be worth it and will slow down your evolutionary growth.

More than thirty meters below the river surface, the water was turbid and the heavy armored beast could only vaguely see a range of more than ten meters.

Just as the heavy armored beast swam for a while, a black shadow more than three meters long came into its sight in the distance, and the heavy armored beast's eyes suddenly lit up.

Compared with humans, the strength of mutant beasts in the water is easier to judge. Basically, the larger their body size, the stronger they are, and mistakes will only be made in rare cases.

For example, the heavy armored beast encountered a two-meter-long mutant fish. Its body was like a sharp sword and its speed was terrifyingly fast.

It only darted past in an instant and tore a mutant fish more than three meters long into two halves. Then it encountered a heavy armored beast and was eaten by it.

But the heavy armored beast also paid a price. The sword-shaped mutant fish cut a wound half a meter long and several millimeters deep in its abdomen.

This was the first time that the heavy armored beast had been injured since its evolution. Although only the exoskeleton armor on its abdomen was cut a little, it still scared it.

After all, the exoskeleton on its abdomen is only two centimeters thick. If the mutant fish was ten times stronger, it would be enough to pose a threat to it.

From that day on, Chen Chu became much more cautious.

At this moment, the mutant fish also discovered the heavy armored beast. Because of the size difference between the two, it did not run away but instead actively approached it.

This is a small mutant shark, covered with gray scales and with a mouth full of sharp teeth.

After discovering the ferocious appearance and thick and sharp limbs of the heavy armored beast, the mutant fish did not launch an attack immediately, but swam around it cautiously.

Seeing this, the heavy armored beast acted clumsy, slowly turned in place, and retracted its limbs to both sides of its body to show fear and defense.

Soon, the mutant shark circled the heavy armored beast several times. Sensing no danger, it swung its tail and suddenly attacked the heavy armored beast from behind.

In just a blink of an eye, it rushed behind the heavy armored beast, opened its sharp mouth wide, and bit the back of the heavy armored beast's head fiercely.

At this moment, the seemingly bulky heavy armored beast suddenly sank, turned around and appeared under the mutant shark, grabbing its body with its four claws.

Tear! !

The heavy armored beast's sharp claws tore the mutant shark's scales, and it bit it hard as it struggled frantically. The horrific bite force directly tore a huge bloody hole in its abdomen.

Suddenly blood spurted out, dyeing the surrounding river water red.

Faced with the heavily armored beasts with four limbs, these mutant fish had no chance to break free once they were caught. They were killed by the heavily armored beasts with their stomachs torn open in just a few bites.

In the blood-stained sea water, the black monster began to eat, tearing off large chunks of fish with each bite, looking increasingly ferocious.
