In the cave, a huge crack under the spaceship is like a hell gate, and there are constantly herds of beasts gushing out of it, their enemy is a huge base, on the wall of the base, there are four hundred mechs, and there are a thousand machine gun emplacements and Gatling machine guns hidden inside the base, their muzzles are blazing, forming a torrent of bullets to put the enemy dead against the wall.

Outside the walls, there were no Brondo scorpions, no bats, but gorillas that were more than three meters tall, but they were mutated, their fists the size of car tires, and they were covered in a thick layer of armor, and their backs were covered with dense metal spikes.

Faced with a hail of bullets, the gorillas raised their heavily armored arms in front of them, and the bullets sparked on their arms.

But even so, these gorillas leave hundreds of carcasses behind for each step forward, and these are not many of them, which is nothing at all for the herd.

Xiao Yu's blue phantom stood on the wall, looking at the dense mutated gorillas outside, with a headache, according to the defense force of the base, it was completely possible to exterminate the beast herd, but helplessly Ye Yitian was not at ease with his artificial intelligence program, only gave him forty percent of the base's firepower control, and did not allow Xiao Yu's subordinate mecha and turrets to fire armor-piercing shells, otherwise more than half of these gorillas would have died.

Come back soon, master! Xiao Yu looked at the group of beasts that were getting closer and closer, and his heart began to get anxious, if the base was breached, then there was an eighty percent chance that the computer room he was in would be destroyed, once the computer room was damaged, then he would be finished, as an artificial intelligence program with a five-year-old intelligence, he still knew what death meant.

Outside the forest, a plane whizzed by, heading towards the interior of the cavern.

"Xiaoyu, how is the situation at the base?" Ye Tiantian sat in the plane, looked at the entrance of the cave in front of him, and asked Xiao Yu about the situation inside.

Xiao Yu, who was in a hurry, was overjoyed when he heard Ye's voice.

"The current situation is okay, the mutant orangutan is still thirty-six .2 meters away from the wall, according to the current speed of the orangutan is expected to be close to the wall in ten minutes, according to the thickness of the wall, it can withstand the orangutan group for ten minutes, so master, you rush back to the base within twenty minutes early." Hearing Ye Tiantian's inquiry, Xiao Yu honestly told the situation of the base.

Ye Yitian frowned after hearing the data reported by Xiao Yu, and then put a hand on his ear and began to think.

"Xiao Yu, I'll give you the control to fire armor-piercing shells and ten percent control of rocket artillery, the password is 532146 and 12865, you don't have to hold on for thirty minutes." Ye Yitian thought about it and shouted into the communicator.

"Okay, no problem" Xiao Yu was overjoyed when he heard that Ye Yitian had given him a higher authority.

In some corners of the base, dozens of rocket launchers slowly rose up, these rocket launchers had not fired a single shell since the beginning of the battle, and now they finally showed their majesty and strength.

At the moment when the rocket launcher was launched, more than a hundred rockets left the barrel with a long tail flame and rushed towards the herd, and the roar continued for a while.

After the dust cleared, the mutant orangutans within the first twenty meters had been emptied, leaving only broken corpses in place, and some unlucky orangutans were in the center of the explosion, and there were no ashes left after death, and they were vaporized in an instant, and this was still the case that the density of the beast herd was too large, otherwise according to Xiao Yu's calculations, the killing range of the rocket artillery would be expanded by twenty meters.

But even so, these orangutans have paid the price of nearly a thousand orangutans.

Inside the base, the bullet of a mecha was empty, and immediately several robots held the ammunition box, walked to the mecha to replace the empty box, this mecha after replacing it with a new bullet, the lethality instantly increased more than doubled, and the bullets on the mecha bullet chain were much larger than the other bullets.

After the mecha was replaced with a new bullet, the armor on the gorilla's arm was instantly torn apart by the armor-piercing bullet like a paper paste, and then it was instantly beaten into pulp by the torrent of bullets, and the orangutan group became unable to move an inch for a while.

At this time, Ye Yitian drove the plane to shuttle quickly inside the cave, one by one difficult action, if the ace pilot of the army saw it, he would be ashamed.

"Xiao Yu, I'm here" Ye Yitian drove the plane and looked at the base in front of him, and sent a message to Xiao Yu.

"Okay, I know," after Xiao Yu heard this, the firepower of the base was strengthened by a point, and the rocket artillery was fired one after another without money.

And the gorillas seem to know the importance of knocking out the plane.

"Roar" An orangutan roared, pulled out a metal thorn on his back, and threw it towards Ye Tiantian's plane.

The metal spikes cut through the space at a speed of twenty meters per second, making a whistling sound, and rushed towards Ye Tiantian's plane.

Ye Yitian looked at the metal thorns that were getting bigger and bigger, his pupils shrank, and he instantly drove the plane upward, and the helicopter was driven by mechanical force to climb up almost vertically, and the huge pressure made the fuselage vibrate constantly, and made a clicking sound from time to time.

The metal spike was only a hair's length away from the tail of the plane, and then fell to the ground due to gravity.

When the other orangutans saw it, they also followed suit, pulled out the metal thorns from their backs, and threw them at Ye Yitian, and in an instant, dense metal thorns filled the cave, and about five thousand metal thorns rushed towards Ye Yitian.

Ye Yitian controlled the plane in the gap between the spikes, constantly shuttling, and those who couldn't dodge were shot off with machine guns, and at this time, the seemingly bulky helicopter became like a loach in Ye Yitian's hands, extremely flexible.

After a wave of metal thorns was dodged by Ye Yitian, a screaming sound suddenly came from the crack under the spaceship, but it came out in the form of infrasound, but although Ye Yitian heard it, the lethality brought by infrasound still made Ye Yitian dizzy for a while.

Just as Ye Tian recovered, the second wave of metal pierced him.

"Not good" Ye Yitian's eyes had just regained a trace of clarity, and he exclaimed as he looked at the metal thorns in the sky, and then immediately jumped off the plane.

"Master" Xiao Yu exclaimed in surprise after watching Ye Tiantian's plane fall.

"I'm fine, you are guarding the base with all your strength now, leave me alone." Ye Tiantian said and threw a punch on the head of an orangutan, and the orangutan's head suddenly sunken, and then slowly fell to the ground.

Inside the base, dense robots are constantly busy, there are five hundred robots in the period to collect these metal thorns, the material of the spaceship is mixed with the flesh and blood of some unknown creatures, it is even harder than Ye Yitian's body, so Ye Yitian also imitates the construction model of the spaceship, most of the walls and buildings of the base are mixed with the flesh and blood of scorpions and bats, although these metal thorns have a great impact, but they are still not enough to break through the armor of the base building, and they fell to the ground, after these robots collected the metal thorns, Put it in an industrial furnace for smelting, and then build a mecha.

"Master, how are you doing?" Xiao Yu couldn't help but worry when he saw Ye Yitian being besieged by the beasts.

"I'm fine, my current position is still forty meters away from the base, and I still have ten meters to break through to the periphery of the herd." Ye Yitian said into the communicator on his ear while splitting the road of life and death with his hands.

However, just when Ye Yitian broke through, a large number of octopuses gushed out of the cracks, these octopuses are also mutated, their appearance is one or two times larger than ordinary octopuses, and they also have eight-day tentacles, but two tentacles have flesh membranes for flight, and the remaining tentacles have spikes at the ends.
