"Start the assault!"

With the arrival of the planned time, Wu Changming issued an order to attack

A squad of Edifier heavy robots formed a group of three in two formations and glided quickly through a pit less than ten meters wide, followed by dozens of hoplites in the gaps of the formation.

Seeing that there was movement in the human position on the opposite side, one or two hundred war insects also drilled out of the front of the Zerg, spreading their legs and rushing directly to this side.

The laser Gatlings mounted on either side of the Rambler began to spin, spraying merciless flames, breaking the frontal war bugs into pieces of minced flesh, and the passage was emptied in an instant.

This 4-meter-tall heavy mobile firepower platform was specially supported by Base 521 and was specially used to cover the heavy infantry.

Due to the easy to defend and difficult to attack in the tunnel, the defending side only needs to find an open area, set up a pocket formation and block the entrance of the tunnel with firepower, and can inflict heavy damage on the enemy. In view of the problem that the tunnel terrain is inconvenient to use high-powered heavy weapons to break through the gaps in defense, Base 521 has specially changed the rambler guarding the safety of the base to a broken weapon that can provide effective support for the infantry.

As the depth of the battlefield widened, small squads of Ramblers were thrown into the battle, and Ramblers and hoplites soon filled the hundreds of meters of tunnel. The team that first broke out of the position had already come into contact with the defensive position of the insect swarm in the open field, and they were greeted by a puff of stinging snake saliva and a continuous onslaught of war insects.

"Launch the neutralizer!"

Seeing that the corrosive saliva was about to cover the Edifier team, the launch tube behind the Edifier fired several ** at the top of the tunnel.

"Sudden ......"

The continuous impact of the ** that was launched burst out on the hard rock at the top of the tunnel, swaying out large patches of white powder that shrouded the entire battlefield.

The spittle of the stinging snake made a clattering sound after touching the white curtain, and the corrosiveness was quickly neutralized, and when it spilled down, it could no longer penetrate the armor, and only washed out shallow marks on the outer surface of the protective layer.

It's rude not to exchange things! Subjected to this disgusting wave of saliva, the hoplites loaded their rage into grenadiers, raining down plasma bullets into the dense formation of the swarm.

The Zerg formation was suddenly cleared by the splashing of high-temperature plasma, but it was quickly filled by the follow-up reserves who were not afraid of death.

"Attention! At 3:00 and 10:00, the Zerg heavy armor unit appeared! Shock-resistant! Don't let them disrupt our formation! ”

Seeing that the opponent broke through the suppression of the stinging snake and rushed out of the mouth of the tunnel, the Zerg not only increased the number of frontal battle insects, but also dispatched the mobile forces arranged on the two wings. Two teams of heavy armor beetles lined up and rushed towards the entrance of the cave, and the huge weight made the entire ground tremble under the bonus of impact.

The first wanderers to break out of the pit turned to face the rushing Bone Helmet, retracting their weapons and legs into their wide bodies with a clattering sound, and with a "clang" the bottom of the ground and a few stakes to hold themselves in place. In a matter of seconds, two sturdy steel walls had formed to protect the two wings of the attack formation.

"Bang!"

"Bang Bang ......"

The sound of the crash was loud, and the bone helmets slammed into the steel wall one by one, and immediately walked a few steps like they were drunk, shaking their buzzing heads.

Before they could come to their senses, countless round things fell from the sky into them, exploding pools of blue plasma.

At the center of the explosion, the bones of the bone helmets that were swallowed by the blue light were gone, and those who were a little farther away and only a little contaminated began to go berserk, and running around the open space was no longer a threat.

Due to the sudden reduction in the intensity of the firepower, the several isolation belts pulled up by the heavy infantry with electroplasma were filled with their own bodies by the swarm, and the subsequent war insects did not hesitate to step over the corpses of their comrades and rush into the heavy infantry.

The insecting insect dog's head quickly retracted, and with its sharp teeth it broke through the armor of the infantry and tore it entirely. The heavy infantry also mercilessly used the electromagnetic rifles in their hands to blur the flesh and blood of the war insects. For a while, the entire battlefield was full of flesh and blood, and the blood of humans and the bodily fluids of the Zerg gathered together, and they were no longer separated from each other.

Never go into grappling!

Liu Yuxin, who was commanding at the front line, decisively gave the order for the mecha to attack the clearance area.

The mecha took the squad as a unit, turned on the super mode, and quickly rushed up from behind, first throwing a round of light bombs, and then ploughing the position from far to near with the weapons mounted on the body as fast as possible. In just an instant, only a few dozen of the Zerg who rushed in were isolated, and they were soon beaten into a sieve by the infantry and mechas.

At this time, the follow-up troops of the slower Rambler also came out of the mouth of the tunnel one after another, using their ferocious firepower to isolate the charge of the swarm from 100 meters away, and gradually expanding their own positions. The mech, which had almost run out of ammunition, also managed to retreat in time and had to evacuate the battlefield with the wounded infantry.

Soon the human position expanded to the entire open field, and the fierce fire of the tiling spread peeled the insect array layer by layer like an onion. Seeing that the enemy in front of him is about to be defeated, a sudden mutation occurs!

Rows of thorns burst out of the ground, piercing a large number of heavily armored infantry, and even the heavily armored ramblers could not resist the onslaught of the stingers, and were pierced one by one. Fortunately, the design of the Edifier is reliable, and as long as the core components are not pierced, they will not be completely damaged. But the heavy infantry suffered heavy casualties, and the entire public channel was full of mourning.

"It's a lurking spider!"

"Lurking spiders! Find it out! ”

……

There was a commotion in the human position, and the terrified infantry had no intention of fighting any longer.

The lurking spider with the cover of the swarm is indeed very tricky, and it can only be hard!

Led by the giant-clan mecha piloted by the third generation of the commando, Liu Yuxin led the alliance's mecha to attack around the battlefield with stinging needles that popped up from time to time, and found and eliminated the black spiders lurking underground one by one. Even if Liu Yuxin was able to accurately locate the lurkers, the mecha brigade had several casualties after the clearance operation, and the casualties of the heavy infantry were even more severe.

Without the cover of the lurking spider, the insect array was quickly crushed by dense firepower, and the entire army was able to advance towards the hinterland of the zerg with great difficulty, but every step was accompanied by countless blood.

Seeing the constantly wailing wounded and cold corpses being transported off the front line, Liu Yuxin couldn't help but feel confused again.

Am I doing the right thing? Am I a little too selfish to have countless people sacrifice for the sake of saving one person?

"Is it worth it?"

Liu Yuxin couldn't help whispering to herself

"It's worth it!"

Wu Changming's deep voice came from the public channel

"We are not sacrificing for a single person, but we are guarding a belief! Guarding the millennia tradition of helping each other, it tells us not to despair no matter what desperate situation we find ourselves in! Because there are countless people who are trying to help you and are trying to save you in a way that you can't see! Hope is always there, no matter when and where! ”
