The backhand stuffed the anchor mine into the hole behind him, and the team immediately formed a battle formation. This kind of insect has been told by Zhang Binhui, and it is a very difficult enemy.

"Be careful, be careful, pay close attention to its movements."

Yan Keshuang muttered to himself, and the electronic sight locked the alien firmly. However, as soon as the dust kicked off the cliff wall, the tarantula alien disappeared, and then there was a "clang" from the rear of the team, and a mecha was blown into the sky.

"Fire!"

Looking at the mecha lying on the ground, its cockpit had exploded, and Yan Yeyang's eyes suddenly cracked. Like a burning fireball, the whole team fired in all directions, and in the upper right corner of the cave, the tarantula alien was suddenly blasted out.

"Kill it!" He Qiliao pulled the trigger heavily, and the three shells locked the alien in a zigzag shape, but the speed of the tarantula alien was too fast, and it flashed again, and it escaped from the encirclement.

The team had to fire again, the full coverage of the fire was enough to force the alien out, but it couldn't kill it, leaving the team with little time to escape.

The tarantula xenomorph must have been this idea, it seemed very leisurely, and under the cover of firepower, it was not in a hurry to escape from the cave, but appeared from time to time to put pressure on the team.

If the team's firepower wanes, the tarantula xenomorphs will attack, dragging them to their caverns.

"You retreat, I'll resist!"

Yan Yeyang was anxious, he jumped out of the battle group and stood alone in the middle of the cave, he planned to use his body as bait to buy time for the team to escape.

As he expected, out of the cover of his comrades, the tarantula xenomorph immediately launched an attack on him.

A wisp of light smoke flashed down from the cliff wall, and the tarantula alien appeared on Yan Yeyang's side.

Seeing that it had a jaw tooth, Yan Yeyang's mecha had fallen into the attack range of the alien.

"It's over!"

Yan Yeyang sighed and symbolically propped up the mechanical arm, and at this moment, a wall of light fell from the sky and slashed at the junction of the alien's head and neck.

It was a long knife, slender and slender, her attack was extremely fast, and with one slash, it was as if it had opened the heavens and the earth, and the sword light flowed like flowing water, easily skimming the alien body.

The jaw tooth that was about to close stopped instantly, and the alien's attack was interrupted halfway. A second later, a "hiss" sound sounded, and the tarantula alien's massive head fell to the ground with bloodshots.

The cold sweat on his forehead seeped into Yan Yeyang's eyes, and the opportunity to come back from the dead made him very surging: "Brother, brother, brother and sister, can you go down, down, next time, can you hurry, hurry, hurry?" I'm quick, quick, scared to pee, pee! ”

Later, Yan Keshuang was overjoyed: "What about General Zhang?" ”

Before he could finish his words, he heard a "click" from hole 33, and a stream of plasma erupted from the hole like opening a gate to release water, and rushed into the cave air a hundred meters away.

Then, with a "snap", a black whirring mass exploded from the plasma column and slammed into the cave wall.

The mass of black smoke billowed in front of the combat team, and it was a tarantula xenomorph that had been charred.

Zhang Binhui's figure appeared at the entrance of the cave: "Everyone immediately retreats into the cave, and we are here to block the aliens." ”

The appearance of the Galactic team immediately aroused the morale of the soldiers, and with a cheer, all the mechs rushed forward, all of them hid in the caves on the cliff wall, and then aimed the barrels of their guns below.

Now, just wait for the enemy to appear.

There was a "boom" sound from the ground on the side, which was blocking the convoy from moving slowly, and the rolling of the locomotive coupled with the operation of the equipment drove the ground to tremble slightly. Each warrior's heartbeat became more and more intense.

With a "whew", a wisp of dust erupted from a hole under the cave, as if the strings had been broken, and the two squads opened fire at the same time, and the dense fire instantly poured down on the opposite rock wall.

In the sound of "da, da", like peeling skin, the rock wall on the opposite side of the cave continued to collapse down, and this already huge cave seemed to grow, gradually spreading to the inside, and the space became larger and larger.

"Wow", the alien launched a counterattack, beams of light erupted from the cave, Yan Keshuang felt a loosening of his feet, the cliff wall he was standing on collapsed, and the mecha suddenly rolled into the cave below.

"Squeak......

It was like seeing a prey appear, and the terrible screams echoed in the cave, and the sound of aliens running could be heard from the hole.

"Lie down!"

Yan Yeyang shouted, and then lay down with his back to the entrance of the cave.

I heard a "boom", and the stone wall on the opposite side was like a breakdown, and the whole stone wall swelled, and then the huge rocks shattered into powder and rushed into the sky.

Yan Keshuang in the cave only had time to turn back to his body, and the mecha he was piloting was as if it had been hit by a huge wave, and the metal body weighing dozens of tons was slapped on the cave wall.

The narrow space, the dense number, the anchor mines planted by the team before erupted with great power, and all the aliens that were about to break out of the hole were shattered into powder.

The explosion caused the cave to collapse, burying all the holes on that side.

"Quick, rescue Yan Keshuang, let's withdraw to the next stronghold."

Yan Yeyang gave an order, and more than a dozen mecha jumped down, they urgently cut through the rubble, dragged Yan Keshuang out of it, and then the whole team urgently withdrew into the hole.

Only half a minute later, there was a "boom" sound in the cave, and the cave wall that had collapsed rose into the sky again, and dense alien shapes took up from the ground like a torrent.

With a buzzing noise, the aliens rose into the air and burrowed into the cave walls on this side.

The insect tide finally came back.

While retreating, Yan Yeyang urgently contacted the large army in the rear, and the information from the rear was transmitted:

The large army was ready for the bugs to come.

On the holographic map, the red tide representing the No. 1 position is ahead, and all the mechs of the team have activated the flight mode, and they are like swimming fish, moving quickly in the direction of the hole, and with a "suddenly" sound, the whole team plunged into a huge underground space.

Position 1, the ambush circle that humans have created for a long time, is a huge underground cavity.

The diameter of the cavity is about ten kilometers, and the height has reached more than five kilometers, and the expeditionary force has broken down the holes here, connecting them all, and this huge underground space has appeared.
