At the bottom of the cave, there was already a mess, a lone mecha was like a madman, she gave up her defense, and blindly only wanted to attack, so more insects stabbed down, and a mountain of insects suddenly appeared on the ground.

Jing Ling hugged Yan Keshuang stupidly, her mecha had been completely destroyed, and drops of tears kept falling on Yan Keshuang's face:

"I know, Keshuang, I really know! Fools, we will never be apart! ”

Radial light flashed out of the pile of insects, as if evaporating, and the aliens had no time to escape, and the powerful energy had already destroyed them

With a backhand stab, Yuan Yuanzi nailed a alien to the wall, Zhang Binhui strictly required her to follow behind, and the task of killing the injured alien was handed over to her, but no matter how hard Zhang Binhui tried, he already felt a little powerless.

Everything is as he expected, even if the expeditionary force is fully prepared, but in the center of the earth, humanity can only be at a disadvantage, and here, it is difficult to deploy scientific and technological weapons.

With a backhand, the mace hit the head of an alien, and the injured alien was shot out, and Yuan Yuanzi next to him skillfully pierced the water-splitting thorn, so there was an explosion in the alien's head, and another commander alien couldn't see it.

"Perform tactic number three, all fighters ready!"

With a roar, Zhang Binhui's order resounded throughout the cave, and this order was also transmitted to the second attack position of the earthlings.

Europa's two undersea bases, Yan Chengjian's heart sank: Could it be that we humans will never have the ability to defeat the aliens? It looks like it's time to carry out the order.

Heartache to heartache, but Yan Chengjian didn't hesitate, his palm slapped heavily on a red button.

"Bah, bah, bah, bah", at the top of the arc of the two submarine bases, a series of fires flashed out, and the two huge roofs with a length of more than ten kilometers were blown open.

The two canopies act like two heavenly domes, isolating the sea from the base, creating a perfect waterless space below, safely keeping the two cracks deep into the ground.

Europa's rock is so strong and stable that it is impossible for seawater to penetrate several kilometers underground.

But now, everything is different!

The two fissures were artificially created by the expeditionary force, and it broke through the rock formations, went straight to the holes, and then- "The sky is falling!" ”

The endless sea water, definitely not millions of tons, perhaps more appropriately described as immeasurable, poured ferociously into those two cracks.

Europa's ice cap made a loud "......buzzing" sound, and then the underside of the ice sheet seemed to be a little white.

Two huge whirlpools appeared, growing bigger and deeper, and the distance between them was getting closer and closer.

The sound of "crackling" kept sounding, and the sea seemed not very happy with the two cracks, which it thought were too small.

So the rock formation began to be torn apart by the seawater, tens of thousands of tons of stones were easily collapsed, and with a "boom", a rock layer with a radius of thousands of square kilometers collapsed, and the two whirlpools finally coincided together.

The sharp sinking of the sea created a sudden vacuum under the ice sheet, and the ice sheet itself weighed hundreds of millions of tons at last crushed itself.

With a "boom", it was like being hit by an atomic bomb, and the white ice field suddenly sank.

The shape was like a whirlpool, the depth exceeded a hundred miles, and then the boundless ice field began to burst, and the expeditionary force base that had been left on the ice field before was like marbles that were bounced into the sky.

The entire planet began to collapse, and the entire ice sheet that was 100 kilometers thick sank in its entirety, and the huge weight slapped heavily on the surface of the sea below.

With a "bang", the ice fountain erupted from the crack in the ice sheet, and instantly went straight to space hundreds of kilometers away.

Everywhere on Europa, whenever there is a crack in the ice sheet, ice fountains like this one go on and on, and the rain and fog make the whole planet a little thick.

Behind the beauty, however, is always more terrifying, and the pressure of the sea water pouring into the holes is so great that now the endless weight of the ice cap has been squeezed down, and the holes have completely become high-pressure pistons.

Deep in the heart of the earth, from the moment they received the order from Zhang Binhui, all the soldiers immediately reacted.

The gunners abandoned their gun emplacements, and they fled for their lives back into the depths of the hole, where the expeditionary force built makeshift ovoid underground shelters in which they sealed the fleeing soldiers to death.

In the automatic bombardment of the gun emplacement, the mech also escaped from the hole, and they retreated into the passage full of locks, and then fixed the mech to it.

The sudden retreat of the expeditionary force made the pressure on the aliens relax in an instant, and the aliens on this side of the hole pounced like dark clouds, they swept through the space for several kilometers, and then burrowed into the hole on this side.

All the artillery that was still firing automatically, was destroyed in an instant, and millions of aliens pursued it, and now, there was only a few kilometers of distance between us and the enemy.

Qian Jin pressed his face against the high-strength glass of the shelter, and he felt a powerful vibration, but it was definitely not from the alien.

In fact, the alien had already approached the cave, and just outside the shelter where Qian Jin was hiding, an alien had already climbed on top of the hatch, and it was about to break the transparent ball of light.

At this moment, the alien's movements stopped suddenly, it raised its head, and a "monstrous" wave was reflected in the eight compound eyes, and the hair on the alien's whole body exploded in shock.

At the end of the overhead, where the hole was turning, there was a "boom", and a column of water smashed on the bend, and the violent column of water went around a large circle along the arc of the hole, and then slammed heavily on the top of the shelter.

I only felt a violent shock, as if the sky was falling apart, and the powerful alien was like a speck of dust being swept away, and the wave head swept over the transparent hatch, and then poured the alien behind it into the depths of the hole.

The water rushing into the hole became more and more turbulent, and at first there were some small crevices that could be seen occasionally, but then the whole hole was completely filled with seawater, and they bombarded as if endlessly.

There was a loud roar from inside the shelter, which shook Qian Jin's head and his head was dizzy, caused by the constant erosion of the sea.

But what worries Qian Jin the most is that the bolts that hold the shelter are constantly hitting the cabin, and the swing of the oval cabin is becoming more and more violent.
