When every underground city was first built, it was considered that once it was invaded by giant beasts, it would need to be attacked by mechas.
Therefore, when building a dungeon, special passages are planned for mechas to pass through.
The pavements of these special passages and the buildings on both sides have been specially reinforced and designed to withstand earthquakes.
Even if the mecha runs at full speed, it will not cause any damage.
Now, the mechas of Luo Yan and others quickly flew through such a special passage and arrived at the underground river.
At the target section of the underground river, emergency repair work has begun. The two bridges on the left and right have lowered their portcullises to intercept the river water.
At the target river section, thick pumping water pipes were put into the river.
Dozens of trucks carrying high-power water pumps were on the river bank, almost occupying the river bank.
All water pumps operate at full power, constantly pumping river water out of the river bed, causing the water level inside to drop at a speed visible to the naked eye.
On the shore, dozens more trucks delivered armor plates to seal the gap.
These armor plates were lifted by a crane and placed on the ground, and then assembled and docked on site by the engineering team.
In the cab, Luo Yan was shocked to see such a large-scale emergency operation for the first time.
Hundreds, even thousands, of emergency repair personnel were dispatched to the underground city.
As well as hundreds of vehicles of various types, the entire riverside area was covered.
So many people are working towards the same thing, the same goal.
This scene alone is touching enough.
Compared with the giant beasts, humans are undoubtedly small.
But even such tiny creatures, with unity and cooperation, can fight against those huge life forms.
Perhaps it is this kind of spirit and will that makes human beings stand out among countless species in their continuous evolution.
Then build your own civilization on this blue planet!
"At six o'clock, a giant flea was found."
"Quantity, seven!"
Kang Shun's voice suddenly sounded on the communication channel.
Luo Yan immediately looked towards the six o'clock direction, and sure enough there were seven giant anchor-head fleas floating in the air.
Among them, three were male fleas and four were female.
The female fleas were far away, their backs arched, their upper dorsal horns shining brightly, and they fired beams towards the emergency repair team on the ground.
Luo Yan was closer and immediately controlled the mecha to attack.
The jets on the back of 'Bi'an' burst into blue flames, and the huge driving force allowed the mecha to arrive in front of the repair team before the beam arrived.
In the emergency repair team on the ground, many workers saw the beams of light coming from the female fleas, and they all exclaimed, dropped their tools, and ran away.
Not wanting to suddenly set off a strong wind, a huge figure then protected them.
The figure was all silver but with tiger stripes. He raised his large shield and blocked the beam.
The supervisor in charge of this team pressed his helmet and shouted: "Don't panic, the mecha will protect us!"
"Everyone, hurry up, finish the work early, and go back early!"
The workers then returned to their original posts, glancing at the mecha in front of them from time to time.
In the cab, Luo Yan easily blocked these beams, and then the aviation cannon on his shoulder roared.
A huge and penetrating gunshot sounded, and the bullets rubbed the air, their surfaces glowing red, and bright light trails were drawn in the air, shooting at the female fleas.
The female fleas immediately changed their attack targets, and the beams on their back corners swept back and forth, cutting and intercepting bullets one by one.
At the same time, the body kept moving, avoiding the attack of 'Bi'an'.
The other three male fleas took the opportunity to rush over, raising their heads in an attempt to knock down the mecha.
But suddenly two black and blue arms appeared in mid-air. The ghost hands covered with complex patterns opened their bows from left to right. They held down the head of a male flea and pressed it to the ground.
boom!
Even though the male flea's head shell was surprisingly hard, it was crushed to pieces, and finally his liver and brain were bruised and he died.
The other male flea was stabbed with a silver spear through its mouthparts. The silver spear threw out a flower, and the male flea was torn apart.
At this time, 'Bi'an' also killed four female fleas. 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, they killed 7 giant fleas in less than a minute, boosting the morale of the repair team and making the workers even more enthusiastic.
At this time, the water level of the underground river had dropped to the bottom, and the uneven river bed was exposed.
Also exposed was the huge gap.
There was still river water emerging from this gap. At this moment, the river water in the gap suddenly boiled.
At the same time, the beast radars of Luo Yan and others flashed spectral signals.
The computer quickly compares the signals and gets the result.
"The target behemoth is confirmed to be the 'Iron Fish'."
"Level: Intermediate Level 3."
"Type: scale insect."
"Characteristics: deep dive, iron bones, violent stabs, steel teeth!"...
boom!
The river in the gap suddenly exploded into a curtain of water, and a black shadow burst out of the curtain of water.
It was a giant fish that looked a bit like a carp, but it was completely black and had bones growing on the outside.
Those bones, one after another, wrap around the body and look very hard, glowing with gold and iron luster.
But as the body of the giant fish moves, the bones undulate and change, and they look like cartilage, which is very strange.
The giant fish fell to the ground, and its wide fins on both sides were like wings and feet, paddling on the ground, causing the iron-bone fish to quickly rush towards the emergency repair team on the river bank.
At this moment, another team came forward.
He Hao was in that team.
His mecha 'Black Thunder' took the lead and stopped in front of the iron-bone fish. Two powerful arms reached forward and grabbed one of the giant fish's iron bones respectively.
The mecha pushed its legs back, and streaks of hot white breath sprayed out from the joints all over its body. The 'Black Thunder' was hit by the giant fish and slid a hundred meters back before stopping.
As soon as the Iron Fish stopped, other mechas took the opportunity to attack, and soon this mid-level giant beast was in danger.
In the end, the giant fish was hit hard by 'Black Thunder' and its head exploded, and it died on the river bank.
Next, except for the anchor-headed giant fleas that invaded the ground before, and a few giant insects that came in from the gaps in the river bed from time to time, no more giant beasts were seen.
Four hours later, the assembled armor plates successfully sealed 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.
In the task just now, I killed five giant fleas and earned 500,000 work points. I couldn't help but sigh.
Money is really hard to make.
At this moment, I felt something in my heart. When I turned around, I saw He Hao, a tall man with a tough guy look, standing behind me holding his helmet.
He Hao suddenly raised his hand, stretched out his finger, and pointed at Luo Yan.
"I will catch up with you soon!"
Then he strode past Luo Yan.
Luo Yan shook his head and returned to his dormitory.
The next morning, just after Luo Yan had breakfast, Yan Wenbo's voice rang out from the communication machine.
"Everyone, come to the war room to gather. The Changping Corps is going to hold an online combat meeting. Come and listen."
"This way you will be clearer about the part you are responsible for."
