These insects, which look huge, are pitifully weak, first of all, they move slowly, like snails, and their huge bodies bring excessive weight, making it difficult for them to move an inch.

The second is the defense of their epidermis, which is as fragile as tofu, which can be broken at the slightest touch.

The weakness of these huge insects once made Lin Han wonder what caused the people of Mongolia to be wiped out, if it was really these huge insects, then how brain-dead would the people of Mongolia be to be wiped out by such an enemy?

But soon Lin Han found the answer.

In fact, it was not discovered by Lin Han, but by Taichu after a deep scanning, it was found at a depth of more than 100 meters underground.

It turns out that these giant bugs are not aggressive, it is more accurate to say that they should belong to the female worm, and the main responsibility is to give birth to offspring.

However, not all females have the ability to give birth, and those that do not have the ability to have children live on the surface, without any protection, and can only wait for death when encountering enemies.

Females that are truly fertile live 100 meters underground, and they eat all the time and give birth to one egg after another.

When I first scanned, I found more than one kind of bugs, these bugs have been detached from the original insects on the earth, they are not large, more are some go-kart-sized bugs, some have sharp teeth, some have big knife-like feet.

These bugs are like those bugs in a movie 'Star Troopers' that Lin Han had seen before, but they were more powerful, and in the picture scanned by Taichu, Lin Han even saw the picture of these bugs cutting through metal ore with their mouthparts and devouring them.

God knows exactly how they evolved. It can even swallow metal ores.

After discovering this, Lin Han gave up the idea of returning to the convoy immediately, and he contacted An Ran and them on the convoy through Taichu, informing them to continue on their way, and he would look for a suitable place to establish a base city in Mongolia.

Lin Han didn't want to find a random place. When everything was ready, he found out that his base was built on the nest of a group of bugs.

He had to find a place where there were no insect nests, and the place should be large and in a good location, preferably close to the river.

It was dawn, and Lin Han was still looking around for the ideal location.

Quite a few have been found close to the river, but there are bug nests nearby.

Lin Han spent the whole day. By the time it got dark, he had searched all of Mongolia, but the ideal location he found was occupied by bugs.

"I have no choice but to grab one." Lin Han said helplessly.

But it's easier said than done. If Lin Han is really allowed to do it himself, I'm afraid this project is not small. After all, the nests of those bugs are at least 100 meters deep underground.

It's hard to get it!

Fortunately, Lin Han has other ways.

Eventually, Lin Han found a place near the Benchagan River.

There is also a nest of insects in the underground here, and the specific number Lin Han doesn't know, anyway, it's quite large.

Arriving at the place, Lin Han flew around in a circle, and then stopped in the air.

"That's it." As he spoke, Lin Han waved his hand. Suddenly, a huge silver-gray robot appeared on the ground.

The robot is so large that it can be seen even from tens of kilometers away.

Lin Han passed through the primordial and controlled the hatch of the robot's head to open. He flew in.

This huge robot needs to be controlled by humans, and Lin Han can let Tai Chu control it, or he can control it himself.

This is also the first time Lin Han has taken it out and used it, which is quite fresh, so he plans to control it himself.

Entering the control room, Lin Han was immediately attracted by the very sci-fi style here.

It's a circular cabin. After Lin Han came in, the entire cabin lit up, and the picture gradually changed to the robot's field of vision. And it's a 360-degree all-round view without dead ends.

"Sir, this robot has a mind sensing system. You can control it with your own mind. Taichu reminded.

"Understood." Lin Han nodded, and with a look of interest on his face, he tried to make the robot lift its right leg.

Outside, the giant robot gently lifted its right leg and stomped it down.

'Boom~! ’

The whole ground trembled.

Lin Han smiled in the control room, and then his face turned straight.

"The main gun on the left shoulder is starting to charge!"

On the screen in front of him, a red progress bar began to overwrite the original green progress bar.

In five seconds, the entire progress bar turned red.

"Charged." An electronically synthesized mechanical sound rang out from inside the cabin.

"Target, one kilometer ahead of the ground, launch!"

A thirty-meter-thick beam of energy shot out from the huge cannon on the robot's left shoulder, and the beam instantly crossed the distance between the two, easily piercing the ground, directly vaporizing all the dirt and other materials in its path.

There was no explosion, no big movement, and a kilometer ahead, a mirror-like hole with a diameter of thirty meters appeared on the ground.

The entrance to the cave extends diagonally down at a forty-five degree angle, and at first glance, the bottom of the cave is not visible at all.

"Taichu, scan it, it didn't penetrate the earth's crust, did it?" Lin Han asked with some concern.

If the earth's crust is pierced, it will have a huge impact on the establishment of a base city on it in the future.

Soon, there was a response from the beginning.

"No, sir, the beam energy only supports 6 kilometers underground, and because it runs diagonally downward, it does not penetrate the earth's crust."

Hearing the answer, Lin Han also breathed a sigh of relief.

At this time, at the hole that had been dug out there, countless insects rushed up, and they rushed out of the ground, in order to find the murderer who killed their mother.

Yes, Lin Han knew that the energy cannon would destroy things within a diameter of thirty meters at most, so he directly aimed at the female worm, under the energy cannon. The female worm had no ability to resist at all, and was instantly evaporated in the middle section, and the dead could not die again.

When Lin Han saw those bugs, he knew that his purpose had been achieved.

Underground warfare has a lot of restrictions for him. Therefore, Lin Han planned to lure all the insects to the surface, so that it would be easy to deal with.

"Main battle weapons, standard all bugs."

"Attack!"

The next moment, the huge robot's body was densely packed with thousands of cannon muzzles and countless shells, and the multi-barreled machine guns on its arms continued to strafe that side.

Machine gun bullets hit the bugs. There was a 'clanging' sound, and the bullets couldn't penetrate their shells.

However, the power of the special cannonballs was enough to kill them, and a large number of bugs died under the explosion of the cannonballs, and more bugs poured out and rushed towards the robots.

"Come on!" Lin Han laughed.

Under several waves of artillery shells. Killed hundreds of thousands of bugs.

But at this time, Lin Han can be regarded as having seen the ability of those fertile female worms, how long has it been? They have given birth to so many Zerg warriors.

The number of insects in a nest has reached millions.

Lin Han controlled the robot, and the robot's huge feet kept stepping on those bugs, countless bugs were trampled to death by him, but more bugs climbed onto the robot's body.

Some of these bugs spew out acid, and those highly corrosive acids can actually corrode the robot's all-gold titanium alloy body, and some bugs are even more exaggerated. Bite directly with mouthparts, and really bite the gold-titanium alloy.

When Lin Han saw it, he directly controlled the robot to jump up. The entire huge body spun in a circle at a height of thousands of meters, and countless insects fell. The huge body fell, and a large number of insects were crushed to death with a bang.

If there were a million Zerg warriors in the entire bug's lair at the beginning, then there are only three or four hundred thousand still alive now.

"Sir, the legs of the fuselage are badly damaged, it is advisable to stop the attack."

The voice of the primordial came to my ears. Lin Han also knew that if he let these insects bite down any longer, his robot would have to become a legless robot.

"Eject." Lin Han shouted.

The next moment. The cabin opened, and Lin Han flew out and put the robot into the system space as soon as possible.

Lost the goal all at once. The bugs were a little overwhelmed.

At this moment, an apparition appeared among the many insects, and where the phantom passed, all the insects were dismembered.

Lin Han held a long sword made of Erdman's metal, and the blade slashed through the bodies of those insects, easily dismembering them all with his unparalleled speed.

Three or four hundred thousand insects looked blankly at the same kind that kept falling around them, and before they could make a move, they had already lost more than half of their kind.

The remaining bugs were frightened, and they began to flee back, trying to escape back into their nests.

At this time, Lin Han suddenly stretched out his hand to suppress it, and the hole on the ground over there collapsed, and the rumbling sound was accompanied by the dust in the sky.

Lin Han continued to slaughter, and in just a few seconds, the remaining hundreds of thousands of insects on the ground were all dismembered into several pieces by him, disgusting yellow-green liquid was all over the ground, and the green grass on the ground was dyed with a disgusting yellow and green color.

"Disgusting!" Stopping, Lin Han shook off the disgusting mucus on the blade of the sword, looked at the insect corpses all over the ground, and could only smile bitterly and began to clean up the battlefield.

But I don't know if I don't clean it, but Lin Han made an unexpected discovery after sweeping the battlefield.

Among the corpses of those insects, Lin Han unexpectedly found a fist-sized mass of metal, and he asked Taichu to identify it curiously, and found that the hardness of these metals exceeded that of gold and titanium alloys by dozens of times.

This hardness, after Edelman Metal and Login, is the third hardest metal known to Lin Han.

This discovery made Lin Han's process of cleaning the battlefield even more motivated, he really didn't expect that these insects would leave some good things for him after they died. (To be continued)
