At the same time, a battalion and a company rushed into the main cave, and several soldiers with portable bunkers rushed to the front, took off the armor plates on their backs and put them together, and immediately turned into a bunker more than one person high and seven or eight meters wide, which happened to cut off the main hole.

There were also reserved firing ports on the bunkers, and first several machine gunners lay behind the bunkers, and the black barrels poked into the lower firing holes; Then several fighters crouched between the machine gunners, the barrel was inserted into the middle firing hole, and finally a row of fighters stepped on the machine gunner, and the barrel was mounted on the upper firing hole.

Upper, middle and lower three layers, squeeze exactly one row.

Two additional squads were arranged behind the bunker, one platoon was prepared with a large number of grenades, the other platoon was armed with grenade launchers, and the two platoons of men and horses could cross the bunker at any time to throw grenades at the enemy.

Everything was ready, the second batch of mechanical spiders had already encountered the enemy army one hundred and thirty meters away, this time they were all far away from the main cave, and the mechanical spiders finally photographed the enemy's situation.

The enemy was still an army of nobles made up of servants, who swarmed in such a dense manner that they almost blocked the passages.

The enemy army is extremely fast, not at all affected by low gravity, and in the blink of an eye, the mechanical spider is overwhelmed by the charging aliens.

Xiao Yuan's heart jumped: "Attention units, if you find the enemy, you will open fire immediately!" ”

He was very glad in his heart, fortunately, the main passage had a small arc more than seventy meters in front of the bunker, if there was no such curve, he would have fought with aliens a long time ago, how could there be time to build a bunker?

The enemy quickly crossed a distance of several tens of meters, and the striker rushed through the corner and appeared in the eyes of a company.

A company commander squeezed out a word from between his teeth: "Fight!" ”

Several fighters immediately opened fire, knocking several of the frontmost enemies to the ground...... The fighters had a tacit understanding for a long time, and they did not fire indiscriminately because of the appearance of the enemy, but only some of them opened fire, and a few enemies came to kill a few, that is, they did not let go of the enemy and did not waste ammunition.

Blood splattered, and several aliens fell lightly, their hands and feet twitching twice from time to time.

Everyone was ready to shoot, but there was no movement behind the corner.

The mechanical spiders that were put into the main cave were all destroyed by the aliens, Xiao Yuan didn't know what was wrong with the enemy, and was about to put a few more spiders over, when a few aliens suddenly jumped out from behind the bend with extremely fast movements!

Like quadrupeds, they landed on their hands and feet at the same time, jumping up and down in the passage, sometimes on the ground and sometimes on the wall, and even hanging upside down from the top of the cave, with incredible agility and speed.

This time, without the company commander giving another order, several fighters fired again, but the enemy's "tactical movements" were too agile to kill the enemy at the first time, and several bullets were wasted to catch the enemy's movement and knock the jumping enemy to the ground.

Without the assistance of biochips, the only countermeasure for soldiers in this situation is to shoot the enemy to death, but the biochip can capture the enemy's movements, slow down and fast forward to predict, which is nothing more than a matter of firing a few more shots.

By slowing down, you can see that the enemy moves so quickly because they stick their hands and feet into the wall, so they find a strong support point and are no longer bothered by the slow movement caused by low gravity.

The enemy who was shot was like a broken sack that had been punched, and it was volleyed by the force of the bullet, and it floated out for several meters before slowly falling.

The soldiers were afraid that the enemy would not die, so they were shot several times one after another, and the enemy would pierce a hole in his body after one shot, and at the same time he would float back because of the momentum of the bullet, and the enemy would not fall slowly under the wall until he was carried back by the bullet.

The soldiers who saw this scene were all stunned, why did they bring such a play? Talent!

The second round of temptation still ended in the victory of the humans, and the noble army suddenly realized that these new humans were more difficult to deal with than the previous ones, so a few seconds later, a large number of enemy troops suddenly poured out of the bend.

If the main cave is compared to a sewer, then the aristocratic army at this time is the sewage that opens the floodgates.

The fighters on the blocking line immediately opened fire with all their might, rifle machine guns rang out, and pulsing cartridge casings jumped out of the chamber and connected in a series in the air.

The enemy's forward was immediately devastated, and those who were shot when they jumped could fall to the ground, and those who died directly on the wall were actually hanging on the walls and the roof of the cave, the scene was indescribably weird.

The charge of the aristocratic army is very brave, but the place like the ground hole is too narrow and too restrictive, and no matter how many troops there are, they can't deploy it, so they can only fight in the main cave that is only seven or eight meters wide, which is not suitable for a large army to charge at all, but it is very suitable for human beings to play their firepower advantage.

The soldiers immediately replaced one magazine with another, the machine guns were also shot in a chain of bullets, the dense rain of bullets blocked the main hole, the charge of the noble army was struggling in the rain of bullets, and more and more corpses were like blood clots blocking arteries, a little silt of the main hole that was not wide.

Some of the enemy troops found that the situation was not right, gave up the advantage of rapid mobility, and raised their arms to fight back with mercerized light, but the number of aliens who can face humans is too small, even if they hit the cover, it is useless, and once they raise their arms, they lose the ability to move quickly, but become a stumbling block for other aliens like corpses.

For a variety of reasons, the encounter lasted only a few minutes before it had to be stopped due to a blockage in the main hole.

Faced with this strange situation, Xiao Yuan wanted to order the troops to blow up the corpses that blocked the main cave and give the enemy a chance to continue charging.

Just as he was hesitating, the aristocratic army had already made a move, and several strands of silk light swept up and down in the main cave, cutting the piled corpses into pieces, and the corpse piles turned into pieces all over the ground in the blink of an eye, opening up the main hole that was clogged.

Immediately, another wave of enemy troops rushed out of the bend, and this time the noble army did not dare to use any more flexible tactics, and honestly hid behind the bend and shot with mercerized light.

They don't show their bodies at all, at most they only stick their arms out, and the frequency of shooting on the human side slows down, and they will only shoot when they see a moving arm.

In a few moments, the warriors wounded a dozen arms, and the enemy fell silent again, and remained silent for a few moments.

Xiao Yuan was uneasy, and hurriedly released a few mechanical spiders to reconnoiter the situation.

The spider was very fast, quickly crawling over a distance of more than 70 meters, and when it reached the corner, only one spider crawled into the corner, and the others found a place to hide.

Whether it is the main cave or the branch hole, the walls and floors and the roof of the cave are very flat, and there is no place to hide before the battle begins. But now there are corpses all over the ground, and spiders the size of fists have places to hide.
