At dawn, Naya Xue's team came to the side of the isolation wall, looking at the kilometer-high wall, Naya Xue always sighed at the greatness of human strength. （）

It was a grand formation, and the walls were made entirely of steel. The walls of the city are full of mechanisms, and all kinds of defensive equipment are embedded in them.

Not only that, with the city wall as the foundation, a large number of defensive spiritual weapons are all over the vicinity, and the treacherous thunder alone is afraid that there are more than 10 billion.

The city wall is a kilometer high and more than two hundred meters wide, and it circles around Planet 3 in a full circle, blocking the alien to the north.

But even so, the xenomorph attacks were still extremely terrifying, and the walls had been breached countless times over hundreds of thousands of years, and each time the steel of the walls was torn to pieces of paper.

But the human race did not give up, and the effect of the city wall is still obvious, it can consume a lot of the living power of the alien, and it is a powerful guarantee that the human race can finally withstand the alien.

So the wall was repaired again and again, and each time it became even bigger.

Flying upwards against this metal body, the figures of the three people looked so small under the sunlight reflected by the city wall, and not far away, Naya Xue saw the figures of countless other support teams, and the humans launched a counterattack.

Zhang Binhui couldn't have predicted what kind of strategic opportunity the destruction of the Netherworld would bring to the Human Alliance, and the alien insect tide was truly contained for the first time.

Behind him, the dust that covered the sky boiled up, it was the mecha troops of the technology planet, they were constantly throwing themselves into the battlefield, and the human beings had already launched a powerful attack on the aliens through the city walls.

Beyond the walls, Nayaxue's party disappeared into the wilderness, and they entered the enemy-occupied territory.

Just a wall, the environment here is completely different from behind the wall, and the northern hemisphere of Planet 3 has completely turned into an earthy yellow color.

A great deal of ground outside the walls was lifted up, as if it had been plowed over, and all the new earth under the ground was turned out.

The woods were no longer visible, and the ruins were everywhere, and in some places they were charred black.

This is the result of the attack of the alien insect tide, they launched an attack from the air, the ground, and the underground without dead ends, this land has been baptized by the fire of war countless times, and the ecological environment of the northern hemisphere has been completely destroyed by the aliens.

Entering the enemy combat zone, all the support teams took the stealth step, and there was no longer half a figure around.

The smell of scorching in the air filled the air, and Naya Xue and the other three carefully hid their figures, and they walked between the mountains and rocks, carefully watching for the traces of the aliens.

Although the large human forces have advanced hundreds of kilometers within the control range of the aliens, there are still a large number of remnants of aliens left behind, and these aliens are very determined to carry out their mission, and they are doing their best to prevent human support from the front line.

After crossing a pile of rocks, Ji Gang in front suddenly raised his right hand, and the three of them immediately hid behind a boulder.

Naya Xue carefully ducked into the stone, and then looked down against the other side of the stone.

Below was a valley, completely covered in rubble, and at the lower part of the valley, a 500-square-meter area was emitting light smoke.

A small battle had just taken place here, and the valley was littered with alien remains, and large swaths of mountain rocks had been stained red with blood.

Right in the middle of the valley floor, two human corpses curled, their bodies twisted at an unusual angle, and the head of one of the warriors was smashed open.

The battle had apparently just ended, and the support team was ambushed by the Xenomorphs, who fought back, but ultimately failed.

There were still four xenomorphs at the bottom of the valley clearing the battlefield, and these four xenomorphs crawled there like spiders, and two xenomorphs even climbed on top of the warrior's corpse, skillfully removing their bracelets.

Xenomorphs also love spirit stones, and that's what they're really trying to do when they're ambushing.

Naya Xue carefully retreated, Ji Gang and Ruxiu had already completed the reconnaissance mission nearby, they made a gesture, Naya Xue understood that there were only these four aliens left nearby.

The battle plan was quickly drawn up, and the figures of the three men seeped into the pile of rubble like ripples.

The xenomorphs at the bottom of the valley are still completing their clearance work, and they have skillfully dismembered the remains of the warriors, and all the spiritual artifacts have been searched for by them.

The two aliens in the center emitted a ripple of divine consciousness, and the aliens on the slopes on both sides gathered together, their steps were very light, and the hillside was full of gravel, but they didn't move one.

Just as the four aliens were about to leave the place, something happened suddenly.

Just above the top of the mountain behind them, a loud "boom" suddenly came, and the mountain was lifted into the air a full hundred meters high, and then a huge amount of debris poured down like an avalanche.

This mountain peak is not high, and after being swept away by this explosion for a hundred meters, the speed of the debris flow is even faster. In the blink of an eye, the mighty stone flow covered the valley like a raging wave.

The four aliens reacted extremely quickly, and they would otherwise go against the edge of the gravel flow, and immediately escaped into the ground with a "whoosh".

As soon as the alien figure disappeared from the ground, hundreds of millions of tons of gravel slammed into the valley floor, and the valley shook suddenly.

The speed at which the alien escaped was extremely fast, and in the blink of an eye, it had been drilled to a hundred meters below, although the weight of the ground suddenly increased, instantly increasing the pressure underground, but these four aliens still seemed to be at ease.

Just as they were retreating, the leader of the alien suddenly let out a "squeak", but before the sound could be released, two huge round boulders on either side of the alien skull suddenly clamped together.

Like popping a tomato, the two boulders were sandwiching the alien head in the middle, and a "poof" sound was heard, and the alien head was sandwiched into sauce by the two boulders.

The three aliens in the back immediately reacted that this was an attack, and they instantly turned red, and all of them entered the battle preparations.

At this time, the second attack appeared.

It was a long sword, the sword light was like snow, and the slash was like a rainbow, and before the outermost alien could react, the long sword had already slashed at the intersection of its head and neck.

As soon as the thin blade of the sword pierced through the junction of the alien's armor, the alien's movements immediately slowed down, its limbs began to twitch, and a large amount of blood poured out from the severed neck.

The other two aliens immediately judged the location of the attack, and two red lights blasted out to the right, a shield appeared in the void, and a girl appeared in embarrassment.

It was at this time that the third attack appeared.
