There was a flash of lightning, and the swift mechanical bug was scrapped.

The surrounding swift mechanical insects took the opportunity to pounce, the big snake was extremely strong, the giant tail flicked, three or four swift mechanical insects couldn't dodge, and were thrown into the big tree, and were immediately damaged.

The powerful swift mechanical worm was as vulnerable as a toy in front of the serpent.

Fortunately, the other insects took the opportunity to pounce, and their sharp claws slashed into the body of the big snake, firmly fixing themselves on it, and in an instant, the big snake's body was already densely covered with swift mechanical insects.

Countless powerful pincers and sharp teeth attacked at the same time, and the big snake rolled back and forth on the ground in pain, and the giant tail swept over, sweeping down several big trees hugged by several people, "rumbling and ......" to the ground, and the battle momentum was very amazing.

But in just a moment, the big snake was almost cut into several pieces, and lay on the ground motionless with Sensen's white bones exposed.

This time, the swift mechanical insects did not immediately dispose of the corpse, but stepped forward to rummage through the head of the big snake for a while, and soon handed it to Zhang Feng with an orange crystal-like thing in their mouths with a few petals.

The voice of the main base sounded in Zhang Feng's head:

"The primary power source can be installed on the combat unit, so that the combat unit has the ability to evolve and is no longer limited by the level of the main base. The highest level of evolution for a primary power source is level ten. ”

Combat units such as the Swift Robot Bug have the ability to evolve again, but they are generally transformed in the main base or sub-bases after evolving, and are upgraded simultaneously.

However, the requirements for the evolution of the main base are very high and difficult, requiring 10,000 units of energy and 100 kilograms of Mithril. Forget about energy, as long as the mechanical insects work hard, they can always save enough, but what is Mithril, Zhang Feng has never heard of it at all, and he doesn't even know if there is one on this planet.

After installing the power source, the combat unit can evolve first, which provides the possibility of obtaining a powerful individual soldier, and Zhang Feng is naturally very happy.

According to the inheritance memory, there is a more advanced energy crystal in the universe called "life source", which can allow combat units to evolve intelligence and become mechanical life.

This made Zhang Feng immediately think of Transformers. In other words, as long as you have enough life sources, you can immediately evolve a bunch of Transformers, which is also too cool.

"Pick a speedy robot and mount this power source on its body. ”

What Zhang Feng needs most now is, of course, a powerful swift mechanical worm, as for the mineral engineering vehicle or a mechanical insect, the number can be used to make up for the lack of level, only the combat unit of the swift mechanical worm, the lack of level is sometimes not the number can make up.

"Yes, master!"

The main base responded with a call and absorbed an ordinary speedy mechanical bug.

Zhang Feng's mood at this time was as nervous as when he was waiting for the rapid mechanical insect to be produced for the first time. What will a robot bug look like with the power source installed?

The time for the transformation is the same as the time for production, which is also ten minutes.

Ten minutes sounds like a short time, but it seems very long for Zhang Feng now.

Finally, with the sound of the main base, the door opened, and the swift mechanical insect walked out in a high-spirited manner.

It seems that it is still pitch black, and it looks exactly like an ordinary mechanical worm, similar to a spider but with a more streamlined appearance, a shiny shell, powerful pliers, and extremely sharp teeth...... It's just that it's much larger than a first-class swift mechanical bug, almost one and a half times larger.

"The second-level speedy mechanical bug, the basic unit of land combat in Atlantis, has strong melee ability and good speed, and its combat power is five times that of the first-level speedy robot. Evolved by installing a primary power source, with a maximum evolution potential of 10, and the way to continue evolving is to devour other mechs or advanced materials. The main base sounded at the right time.

"The combat power is five times that of the first-level rapid mechanical worm?" Zhang Feng's eyes lit up, this is a big improvement!

"Can you evolve by devouring other mechanical bodies, can you also evolve by devouring first-level swift mechanical insects?" Zhang Feng asked.

"Yes, master. The main base replied.

Zhang Feng nodded and ordered: "Come over five first-level swift mechanical worms, besiege this second-level swift mechanical worm!"

Soon, five first-level speedy mechanical insects surrounded the newly evolved second-level speedy mechanical insects in the middle.

"Click...... The swift robots waved their pincers and claws menacingly, their sharp, long, sharp teeth one by one.

"Let's go!" Zhang Feng gave an order, and the six swift mechanical insects moved at the same time.

"When!" The second-level speedy mechanical insect first crashed into a speedy mechanical worm, knocking it to the ground and breaking out of the encirclement in one fell swoop.

At the same time, two large iron pincers clamped the unlucky swift mechanical worm, and with a single force, the black and shiny metal shell was torn apart like paper paste.

Then, with a much faster speed than the first-level speedy mechanical insect, the second-level fastening mechanical insect kicked on the ground with its mechanical legs, and pounced on the second first-level rapid, "ding!" and the sharp front claws cut it from it.

At this time, the third first-level speedy mechanical insect just pounced, and as soon as the second-level speedy mechanical insect turned around, the pincers attacked like lightning, and the enemy was firmly clamped.

"Stop!" Zhang Feng hurriedly shouted.

In the blink of an eye, the two first-level swift mechanical insects were destroyed, if it wasn't for their timely shouting, the number would have increased to three, and the first-level swift mechanical insects didn't even capture the shadow of others, and the battle situation reached this point, and the victory and defeat had long been clear.

"Haha, good worm!" Now that he has more than a hundred first-level swift mechanical worms, he is not too distressed to lose two.

As for the two damaged corpses, there is no need to recycle them, anyway, the time it takes to create new combat units is not much different from the time it takes to repair them.

"Devour these two first-level swift mechanical bugs!" Zhang Feng ordered.

The second-level swift mechanical worm's eyes flashed red, and he walked towards the two scrap iron corpses, and then pressed his body against one of them, and the parts that the two rapids touched seemed to melt, and the remnant slowly fused into it.

In about three or four minutes, the process is over.

Then, in the same way, absorb the second damaged first-class rapid.

Absorbed two huge first-level swift mechanical worms, the second-level swift mechanical worm turned out to be the same as before, neither getting bigger nor producing other changes, which made Zhang Feng very puzzled, where did such a large piece of metal go?

"What's going on? Nothing has changed?" Zhang Feng asked curiously.

"The matter devoured is not enough to cause evolution, and it takes ten first-level rapids to evolve to the next level. The main base replied.

"I see. Zhang Feng groaned.

However, for now, he is really reluctant to give up on the ten first-level rapid mechanical insects, so he can only give up for the time being.

For Zhang Feng, who has always been insecure, the most powerful combat unit is, of course, to be placed by his side.

The number of troops guarding the main base has increased to fifty first-level speedy mechanical insects and one second-level rapid mechanical worm, and the black pressure is overwhelming, and it looks very majestic.
