At the beginning of the construction of each underground city, it was considered that once it was invaded by a giant beast, it would need a mecha to face it.

Therefore, when building dungeons, there are special passages that can be planned for mechs to pass.

The pavement of these special passages, as well as the buildings on both sides, have been specially reinforced and have been designed to be earthquake-resistant.

Even if the mech runs at full strength, it will not cause any damage.

Now, the mecha of Luo Yan and the others rushed through such a special passage and arrived at the Dark River.

At the target section of the dark river, emergency repair work has begun, and the two bridges on the left and right have lowered the suspension gates to intercept the river water.

At the target section of the river, thick pumping pipes were lowered into the river.

Dozens of trucks carrying high-powered pumps on the riverbank almost fill the riverbank.

All pumps operate at full power, constantly pumping water out of the riverbed, allowing the water level inside to drop at a rate visible to the naked eye.

On the shore, dozens of trucks were delivered to block the gap.

The armor plates were lifted by a crane and lowered to the ground, where they were assembled and docked on site by the engineering team.

In the cab, Luo Yan was shocked when he saw such a large-scale emergency operation for the first time.

The dungeon dispatched hundreds, if not thousands, of emergency repair personnel.

and hundreds of vehicles of all kinds, covering the entire riverbank area.

So many people are working for the same thing, the same goal.

This scene alone is touching enough.

Compared to the behemoths, humans are undoubtedly small.

But such a small creature, with its unity and cooperation, can fight against those huge life forms.

Perhaps it is this spirit and will that makes human beings stand out from countless species in the continuous evolution.

And then on this blue planet, build your own civilization!

"At six o'clock, a giant flea was found."

"Quantity, seven!"

In the communication channel, Kangshun's voice suddenly sounded.

Luo Yan immediately looked in the direction of six o'clock, and sure enough, there were seven anchor-headed giant fleas floating in the air.

Among them, three are males and four are females.

The female fleas had arched their backs from a long distance, and their upper dorsal horns glowed, and the beams of light swept towards the repair team on the ground.

Luo Yan was close, and immediately controlled the mecha to meet the attack.

The jet behind the 'Raccoon' burst into blue flames, and the huge impetus caused the mech to rush to the front of the repair team before the beam arrived.

In the emergency repair team on the ground, many workers saw the beam of light shot by the female flea, and they all threw down their tools in surprise and ran into the distance.

Not wanting to suddenly set off a violent wind, a huge figure then protected them under their figures.

The figure was silver and white, but tiger stripes appeared, and he raised his large shield to block the beam of light.

The director in charge of this team pressed his helmet and yelled, "Don't panic, the mecha will protect us!" ”

"Hurry up, finish early, go back early!"

Only then did the workers return to their original posts, glancing at the mecha in front of them from time to time.

In the wheelhouse, Luo Yan easily stopped these beams, and then the aviation cannon on his shoulder roared.

Large, penetrating cannon rang out, bullets rubbing the air, the surface reddened, and a bright streak of light in mid-air, strafing the female fleas.

The female fleas immediately changed their targets, and the beams on their dorsal horns swept back and forth, cutting and intercepting bullets one by one.

At the same time, his body kept moving, dodging the attack of the 'Fox'.

The other three males took the opportunity to rush and arch their big heads, trying to knock down the mech.

But suddenly, two black and blue arms poked out in mid-air, and the ghost hands full of complex patterns opened their bows left and right, holding down the head of a male flea respectively, and pressing it to the ground.

Bang!

Even if the hardness of the male flea's skull is amazing, it is crushed, and finally the liver and brain are smeared on the ground and die.

The other male flea was stabbed through the mouthparts with a silver spear, and the silver spear threw out a spear flower, and the male flea was torn apart.

At this time, the 'Raccoon Fox' also killed the four female fleas, and Luo Yan looked back and saw that the magic machine 'Eight Gates' and Dugu Changxin's 'Flying Lightning' were near him.

With the cooperation of the three mechas, it didn't even take 1 minute to kill 7 giant fleas, which greatly boosted the morale of the repair team, and the workers were even more enthusiastic.

At this time, the water level of the dark river had dropped to the bottom, and the uneven riverbed was exposed.

At the same time, there is also the huge gap.

There was still water coming out of the gap, and at that moment, the water in the gap suddenly boiled.

At the same time, Luo Yan and the others' giant beast radars were all flashing spectral signals.

The computer quickly compares the signals and gives the results.

"Confirm that the target behemoth is 'Iron Fish'."

"Level: Intermediate Level 3."

"Type: Scale Worm."

"Features: Deep Diving, Iron Bone, Violent Thorn, Steel Fang!" ......

Rumble!

The river in the gap suddenly exploded into a water curtain, and in the water curtain, a black shadow collided out.

It was a giant fish, somewhat like a carp, but it was pitch black and had bones growing on the outside.

The bones were one after the other, wrapping around the body, and they looked very hard and shiny with gold and iron.

But as the giant fish moves its body, the bones rise and fall, and they look like cartilage, which is very strange.

The giant fish fell to the ground, and the wide fins on both sides were like wings and feet, paddling on the ground, and the iron-boned fish quickly rushed to the repair team on the riverbank.

At this moment, another team came up to meet them.

He Hao was in that team.

His mecha 'Black Thunder' took the lead and stopped in front of the iron fish, and two powerful arms reached forward to catch the giant fish with one iron bone.

The mecha propped its legs back, and the joints of its whole body spewed out a scorching white breath, and the 'Black Thunder' was hit by the giant fish and slipped a hundred meters later, and then stopped.

As soon as the iron-boned fish stopped, the other mechs took the opportunity to attack, and in a short time, this mid-level giant beast was in danger.

In the end, the giant fish made 'Black Thunder' blow to the head, and died on the bank of the river.

After that, except for the anchor-headed giant flea that had invaded the ground before, and a few giant insects that occasionally burrowed in through the gap in the riverbed, the giant beast was not seen again.

Four hours later, the assembled armor plates successfully closed the gap.

In addition, outside the city, after the Changping Corps discovered the entrance to the passage and destroyed it, this hidden danger was finally eliminated.

After completing the mission, Luo Yan returned to the camp.

He did the math.

The task just now killed five giant fleas, and only earned 500,000 labor points, and I couldn't help sighing.

Money is such a thing, it's really not easy to make money.

At this time, I felt a feeling in my heart, and when I turned around, I saw a tall man, and He Hao, who looked like a tough guy, was standing behind him with a helmet.

He Hao suddenly raised his hand, stretched out his fingers, and pointed at Luo Yan.

"I'll catch up with you soon!"

Then he strode past Luo Yan.

Luo Yan shook his head and returned to his dormitory.

The next morning, as soon as Luo Yan had breakfast, Yan Wenbo's voice sounded on the communication machine.

"Let's all come to the war room, the Changping Corps is going to hold an online combat meeting, you all come and listen."

"Then the part of you that is responsible for yourselves is clearer."
