Outside the walls, an even more fierce bloody battle was going on.

The Wind Mantis is still the front line.

They ran fast on the ground at a speed of more than the speed of sound, and as they ran, one mine after another exploded, but because the speed of the mantis was too fast, these mines did not even hurt the mantis, only a few missed mines effectively injured some bugs behind, but with little effect.

The mine array that Shen Yi had painstakingly laid was broken like this.

Fortunately, the wall blocked the attack of the green mantis, and although these green mantis were not bad at jumping, they were far less fast than running on flat ground.

When they leapt towards the wall, they are simply live targets, and they are covered in blood by thousands of bullets, and even if they are not killed, the powerful impact will send them back out of the wall.

With the help of the terrain, all the soldiers and Terminators opened fire with all their might, holding the high ground to the death.

However, more and more Zerg were still attacking in the distance, and the large swarms of stinging snakes gathered together, spitting out corrosive venom that almost flooded the entire wall.

Some soldiers were accidentally spit out, and even the mechs they were wearing could not resist the strong corrosion, and they fell off the wall in mourning.

"Launch a nuclear bomb!"

Shen Yi had already ordered loudly, and a small-yield nuclear bomb had flown towards the outside of the city wall, exploding a small mushroom cloud in the swarm.

In fact, a nuclear bomb with a small yield of this kind has very little effect on the Zerg.

Starting with difficulty four, most of the lives are extremely resistant to nuclear bomb attacks.

At the beginning, Shen Yi killed the million-strong army of the Three Kingdoms with a nuclear bomb, and that was because he used a large yield of 500,000 tons, and the bombs were all low-level soldiers who won by numbers, formations, bloodlines and other auxiliary means.

Even so, there are still thousands of people alive with that nuclear bomb.

The life above the intermediate level of the fourth difficulty can resist a 500,000-ton nuclear bomb, and a small-yield nuclear bomb like this can cause hundreds of lives to the Zerg at best, and the effect on the advanced level is even lower, and even the death ripple of King Kong may not be compared.

Considering the price of nuclear bombs and the one-time use method, it is really not as good as skills.

However, Shen Yi happened to have stock in his hand, so he unceremoniously took it out and used it, no matter what, the attack range of the nuclear bomb was still much larger than the Death Ripple.

At this moment, a few nuclear bombs went down in a row, taking advantage of the fact that the other party was gathering more, Shen Yi directly emptied the nuclear bombs in his hand, and then shouted: "The fortress fires, and all the batteries are aimed outside the wall!"

The fortresses that had been holding the gap in the wall and the forts that were stationed all over the wall were simultaneously powerful, and countless huge runways fell in the swarm, blasting out a sea of blood.

Soldiers recruited from the system are mainly responsible for the use of the battery.

These double S-level turrets are extremely powerful, and they are all range attacks, under the operation of the soldiers, the turrets emit amazing flashes from time to time, and the thick energy pillars from the four energy cannons swept away all the zergs in a line.

However, more Zerg are still falling in the sky.

A huge firefly with the image of a galactic warring team was falling on the wall, and when it opened its mouth to the side of the wall, it was a large flame, burning seven or eight soldiers in one go, and then crashing headlong into the turret, overturning the fortress cannon directly.

The flood rushed over with a wild scream, and jumped violently, and the overlord's axe slashed angrily at the fire-breathing worm, and the axe failed to cut the fire-breathing giant in half as expected, but instead plunged half of the axe into the fire-breathing insect's body.

The fireworm turned its head with a painful cry, and it was a pillar of fire against the waves.

"you/!" Hong Lang met the flames against the waves of fire, and punched the fire-breathing insects with great force, knocking the fire-breathing insects away from the city wall.

As the king of heads-up, Hong Lang's task is to clean up all the bugs that fall or rush to the wall.

However, the wall is too long, there are too many insects, and it is far from enough to rely on him, insects are falling everywhere in all directions, and this overwhelming insect rain does not know when it will end.

Even more striking is the sky, where countless wyverns are pounced.

They spread their wings several meters long and flew over the fence, and when they flew up again, they had already grabbed a soldier and didn't need to be killed, they simply flew high into the air, and then released their claws, and the soldier had fallen from the sky.

Some soldiers who were lucky enough not to fall to their deaths were directly pounced on by the insects on the ground and tore them apart.

The war was so cruel, there was a sea of blood boiling everywhere, even Shen Yi, in this sea of insects, couldn't help but feel a sense of powerlessness.

However, this feeling was only a flash, and he shook his head and swayed it, but the Vulcan cannon in his hand was fired more fiercely.

If that's the ultimate fate of adventurers, let the storm come harder.

Whether it is Shen Yi and other adventurers, or soldiers, at this moment, they have no time to care, attack with all their might, kill the enemy or be killed by the enemy.

In the onslaught of this sea of insects, many of the skills that were once used are meaningless, blocking and dodging are no longer king, and strong defense and ferocious attacks are the foundation of survival.

Eighteen immortal birds had all flown in the sky, fighting, the fat man released the flame chariot, rampage in the sky, the long river of flames rolled and flowed, the torrent of heaven and earth spread in all directions, and a frenzy of flames was set off on the battlefield, burning the swarm of insects to let out a loud and miserable scream.

The Broken Blade team had always felt that the strong lives of the undead birds were wasted, but under the onslaught of countless flying dragons, the lives of the undead birds were also rapidly falling.

In just a moment's effort, two immortal birds have been directly killed, but fortunately, as a summoning life, they can be resurrected, and the fat man only needs to protect the entity immortal bird.

It was precisely because of their presence that those ferocious wyverns in the sky failed to inflict too severe a blow on the ground soldiers.

"Damn, there are too many of these bugs!" Zhou Yiyu was also firing with his Vulcan cannon, wearing soul armor, he didn't use the giant to transform, because it was impossible to kill them all, not to mention that the brood in the sky has not yet fallen, these broods are not just used to transport troops, they are the most powerful bosses themselves.

Stronghold Titans must be used in critical moments.

Before he finished speaking, there was a huge vibration on the ground, and a giant insect suddenly burst out of the ground, and two giant feet like sickles slammed into Zhou Yiyu's body, knocking him out with a blow.

Zhou Yiyu howled, flying in the air and firing at the same time, only a large number of bullets popped out on the insect, leaving only white bullet casings.

"Damn, this guy has reinforced armor, it's a tank bug, be careful that it can destroy the city wall, kill it quickly!"

There are many species of Zerg, and even the same species has different branches.

There are specialized reconnaissance classes for hosts, as well as specialized transport classes.

The tank bugs of the main defense class also include the burrowing class and the city wall destruction class.

This tank worm is both, and at this moment it is constantly hitting the wall, and in the rumbling impact, the steel wall has begun to deform.

More tank bugs are coming.

Shen Yi shouted: "Yi Yu, you go to defend the wall instead of Hong Lang, Hong Lang, you go outside the wall, kill those tank worms, don't let them attack the city wall, everyone shrinks the defense line!"

"Understood!" Flood Wave had rushed over again, jumping directly from the wall: "Splash Attack!"

The splash attack of the Overlord's Axe unleashed, and pieces of axe light spread in all directions.

The insects rushing outside the wall were swept by this axe light, as if they had been cut by the flood wave itself, and they were bleeding one after another. After a series of axes, the flood wave had already slashed and exploded the defensive giant insect that was said to be the most difficult to kill.

"Whew!" he raised his head to the sky and howled, and he had activated his acceleration form, and rushed towards the insect swarm outside the wall, like a steel chariot, killing a bloody path in the insect swarm, and from time to time a round of aura shone on his body, which was automatically triggered by the Whirlwind Array skill. This skill does not need to be used, as long as it is charged while accelerating, it will automatically have a chance to be effective.

The flood wave charged and slashed as if it had entered a no-man's land.

His split attack originally needed to hit to exert its effect, and the use efficiency was lower than the original state, but now there are bugs everywhere, and it really hits at will, and with the auxiliary bonus of the splash attack, the effect of the split attack is maximized, and it really rushes to kill wherever it goes.

But he attacked fiercely, and he was beaten fiercely.

Rao is he is wearing a guardian suit, with a damage reduction of up to more than 30 percent, and he also has protection methods such as vampire attacks, and his vitality is still declining rapidly, and the fat man, Zhao Ling'er, Michel, Kafka and other people with medical and protective means are almost constantly throwing various skills at Hong Lang's body one after another.

At that moment, the waves were rampant, and all the way to it, it swept out one blank area after another.

However, as the splash attack time expires, the power of the flood wave group attack is greatly reduced.

Shen Yi shouted again: "Langqiu is back, King Kong catches it!"

"Understood!" Hong Lang shouted violently, turned around and opened a void passage, and the person had appeared directly on the wall, cooperating with Zhou Yiyu to continue to guard the city wall.

King Kong has unleashed his bloodline ability to break through the wall.

At this time, his mental power was exhausted, and he even used up his spiritual power potion, and the next thing was to fight with his bloodline.

Fortunately, his bloodline was originally suitable for group battles, and after the flood wave withdrew, King Kong took the outside position.

Under the transformation of the demon god, destroying the heavens and the earth, the purgatory of the ten directions, the poisonous clouds, the white frost and other bloodline moves were thrown out one after another without money.

He didn't use the root of all evil, but the three demon gods took turns, so that he could play various group moves more consistently, and the burst damage was weaker, but the comprehensive damage was higher.

The battle with the Zerg belongs to the level of war, and temporary strength is no longer so important, and persistence becomes more critical. Fortunately, everyone's will has now reached four hundred, and they have been boosted by the spring water, and their physical and mental strength have recovered extremely quickly.

After King Kong's bloodline skills were also exhausted, Zhao Ling'er rushed out.

The wind, snow and frost danced in a wide range of areas, and continued to block the footsteps of the swarm.

When Zhao Ling'er's skills are exhausted, it will be the God of War mecha that will be dispatched.

When these gods of war fought against Sargeras, because Sargeras's attacks were too fierce, Shen Yi didn't dare to let them go in hand-to-hand combat, so they could only shoot from a distance, and they couldn't really play the role of the god of war mecha in group combat.

But in this great battlefield where ten thousand insects are galloping, in the face of an existence like the Endless Zerg, it is the most suitable place for the God of War mecha to exert its combat power, and its role is even stronger than Megatron.

The guns roared wildly, hitting the attacking Zerg, and whenever the Zerg broke through the blockade, the God of War mecha would raise its light knife and slash hard.

The God of War Light Knife under the bonus of the Nine Heavens Star Luo Array is more powerful than the machine gun, although the vitality of the Zerg is strong, it is still chopped by a knife, and at the same time, all kinds of energy light shine on the God of War mecha from time to time.

When the God of War was almost unable to withstand it, the flood wave had recovered, jumped out and launched a splash attack to continue slashing, and when he finished a round, King Kong continued to ripple the god of death, so it formed a cycle with Zhao Ling'er's God of War mecha and others, blocking the torrent of insects.

Gentleness leads the Destroyer against the Zerg within the walls, avoiding the harassment of their sneak attacks from behind, these Zerg are relatively scattered due to the severe blows they received at the beginning, and only Gentle Speed is suitable for dealing with them, for which she has also opened her bloodline.

Shen Yi was mainly responsible for the air, because at this moment, two undead birds died, and the fat immortal birds alone could no longer stop the army of flying dragons.

As a result, the battle was temporarily stalemate, and the swarm was ferocious, but it was never able to break through everyone's defenses.

However, as if they could not be killed, these insects were still pouring one after another, and even the Broken Blades gradually felt powerless under the tide of attacks.
