As soon as the octopuses appeared, the size of the orangutans suddenly shrank to the size of ordinary orangutans, and the armor on their bodies fell to the ground, and they raised their armor and began to run towards the base.

At this time, Ye Yitian had already broken through the siege of the orangutan group, came to the gate of the base, and then entered the base.

In the middle of the base, there is a mecha, this mecha is four meters high, has four arms, and has a rocket launcher on its shoulder, all dressed in golden yellow, Ye Yitian immediately sat on it after seeing it, and at the same time, inside a warehouse in the base, five hundred mecha flew towards the sky with flames on their backs.

These mechs are mixed with the flesh and blood of the Brondu scorpion, and their bodies are reddish-brown in color, and their hardness is much higher than that of other mechs.

"Xiao Yu, you come to stop the octopus school, and I will deal with the orangutan group." After Ye Yitian sat on the mecha, he immediately arranged the battle strategy.

"Okay" Xiao Yu's phantom suddenly became solemn as he stood on the wall and watched the dragon-like school of octopuses rushing towards the base.

Ye Yitian drove the mecha to fly up the wall and watched the frantic orangutan finger just pull the trigger, and the rockets on his back whistled out one after another, and the bullets poured out like a flood, and the bullet casing turned into a hill in less than ten seconds.

At the same time, the remaining rocket artillery machine guns at the base also began to go into full-fire mode.

For a time, artillery fire and gunsmoke were everywhere, and any written description was pale and weak.

The gorillas who rushed to the front outside the base were beaten into flesh by machine guns, and the orangutans in the back still stepped on their corpses and continued to rush forward, and the gorillas at the back pulled out the metal thorns and threw them at the base, these metal thorns were not enough to break the armor of the mecha but some unlucky mecha were pierced by metal thorns to the joints, Ye Yitian did not assemble armor in the joints in order to keep the mecha flexible, and then this big defect was suddenly revealed.

Some mecha arms were pierced in the joints, and the whole arm suddenly burst out of a ball of electric sparks, and the bullets could not be fired, which was relatively lucky, and some mechas were pierced in the connected parts, and the whole arm fell off directly.

Almost at the moment when the mecha was damaged, hundreds of repair robots came to the city wall with parts and began to repair the damaged mechs, some of which had broken arms and legs, and some of the arms and leg wiring were damaged, unable to move and fire bullets.

These damaged mechs were unable to fight, creating a firepower gap in the defensive forces, and for a moment the orangutan swarm advanced a little faster.

"Xiao Yu, give me fire support, I have some damage here" Ye Yitian shouted into the communicator as he watched the group of orangutans getting closer and closer.

"Master, I'm also under a lot of pressure here, I can only give you five percent of the fire support, and it can only last for ten minutes, otherwise I have a ninety-five percent chance of losing here." Xiao Yu looked at the dense school of octopuses in the sky and gritted his teeth.

"Yes, you just need to hold it for five minutes," Ye Tiantian said with a frown as he looked at the dense school of octopuses in the sky.

Inside the base, some rocket launchers and machine guns were slaughtering octopuses when they suddenly turned their guns around and fired at the orangutan swarm.

With Xiao Yu's fire support, the orangutan swarm moved much slower, but soon these mutant orangutans reached the bottom of the wall, and they used metal thorns to constantly tie the wall, Ye Yitian watched the movements of the orangutan swarm and immediately understood what they were going to do, they wanted to stick the metal thorns into the wall, and then use the metal thorns as ladders.

However, the idea of the orangutan swarm is good, but the reality is very cruel, the wall of the base is poured by Ye Yitian with the flesh and blood of alloy mixed mutant bats at a large price, and it is much stronger than metal thorns in terms of hardness and toughness.

It takes about ten orangutans to insert a metal spike into the wall, and most of them are knocked out by indiscriminate fire.

These orangutans looked at the metal thorns that were knocked out, and roared angrily, after the metal thorns were inserted into the wall, they hugged the metal thorns and blocked the bullets with their bodies, and the orangutans behind stepped on the corpses of the orangutans in front of them and continued to climb up, this behavior finally made Ye Yitian a little moved.

When the octopus saw that the orangutan swarm was about to climb the wall, they also separated from the large army to support.

These octopuses surrounded Ye Yitian and his mecha one after the other, and Xiao Yu immediately turned his gun after seeing Ye Yitian being surrounded, and tried his best to save Ye Yitian from the encirclement, but the large army of the octopus group seemed to know Xiao Yu's thoughts, and dragged Xiao Yu's firepower to death, causing Xiao Yu and Ye Yitian to be isolated.

"Master, how are you" Xiao Yu attacked with all his strength and asked about Ye Tiantian's situation.

"I'm here for a while, you can charge the grid and the high-voltage electromagnetic blade now, they isolate us, and we isolate them. Ye Tiantian said while tightening the trigger.

"I see, it's about ten minutes to recharge." After Xiao Yu heard Ye Tiantian's order, he immediately charged the power grid and the high-voltage electromagnetic blade.

"Ten minutes later, we will first go all out to eliminate the orangutan swarm, there are too many octopus schools to be eliminated in a short time, and give me the map of the base, my vision is blocked, I can't determine my location." Ye Yitian said as he looked at the red eyes around him.

The attack power of the octopus school and the mutant bat is too different, the mutant bat, the claws can easily tear through the armor of the mecha, and the octopus school can only leave white marks on the armor, but the huge number makes up for this defect, and the white marks become ravines, and then the armor is broken, and the internal lines are damaged.

One of the mechas, besieged by a school of octopuses, the armor was full of ravines, Ye Yitian decisively let this mecha disintegrate, after the disintegration of this mecha, the high-energy battery floated in the air, and then burst out with a violent light, and the octopuses within twenty meters around were immediately vaporized and some octopuses were burned to the ground, which was just a microcosm of the battlefield.

In the encirclement formed by the dense octopus, a mecha with four arms and a whole body of golden yellow stands on the wall, the armor of this mecha has been torn apart, revealing a young man with a black body from the inside, the octopus group immediately gave up the attack on the mecha after seeing the young man and began to attack the youth with all his strength, the dense tentacles kept swiping back and forth, but there was no white mark left on the black skin, only the octopus was attached to the face to block the view, and the young man's hand would let go of the trigger of the mecha, Tearing the octopus that blocked the view to pieces, this young man was Ye Yitian.

Ye Yitian looked at the red color around him, frowned, and was annoyed, his communicator, the helmet of the mecha had been damaged, and now it was completely isolated from the outside world, and now he could only calculate the situation of the base based on the data from three minutes ago.

"Master, can you hear it" Xiao Yu kept calling Ye Tiantian through the communicator, but there was no response, and three minutes ago, there was no signal.

At this time, Ye Yitian was still sitting in the mecha, constantly waving his mechanical arm to kill octopuses one by one.

The bullets of the mecha have already been exhausted, and the rockets have also been launched, and the hill of bullets and octopus corpses piled up next to it has completely buried the legs of the mecha, Ye Yitian had to eject the ejection blade inside the mecha's hands and charge the ejection blade.

Ten minutes passed, and in the corner of the base, there were Tesla coils slowly rising, these coils could not be found if you didn't look carefully, but at the top of the base, a circular metal ball with a radius of ten meters rose, and after the metal ball was raised, electric sparks continued to emerge from it, and then a blue amazing light erupted.

When the schools of octopuses scattered around the base saw it, they immediately gathered together in the air and rushed towards the metal ball.

Ye Yitian, who was waving his mechanical arm, saw a blue light in front of him, and as the blue light became brighter and brighter, the octopus gradually left, and Ye Yitian saw the situation of the entire base again.

"Master" Xiao Yu immediately projected a phantom shadow next to him after seeing Ye Yitian's figure, and then threw himself into Ye Yitian's arms, but the phantom passed through Ye Yitian's body.

"I'm fine," Ye Yitian said, looking at the school of octopuses that were heading towards the metal ball, taking a deep breath of air.

The density of octopus schools just now is too high, resulting in a very scarce amount of oxygen, and if it weren't for the appearance of metal balls, Ye Tian might have been suffocated to death.

Just as the octopus was heading towards the metal ball, a flash of lightning came out from the Tesla coils distributed in the base, which was transported towards the metal ball, forming a power grid that enveloped the entire base, and all the octopuses that touched the grid were electrocuted into coke.

"Why is there only the power grid?" Ye Yitian looked at the sky full of octopuses and asked.

"The high-voltage electromagnetic blade was delayed by one minute due to the destruction of several generator sets by a school of octopuses, and there were thirty seconds left to start." Xiao Yu stood behind Ye Tiantian and replied in a sweet voice.

"Xiao Yu, you now go all out to destroy the octopus swarm, and I will deal with the orangutan swarm" Ye Tiantian said as he suddenly turned around and swung the catapult blade to stab into the body of an orangutan, and then the electricity on the catapult blade instantly electrocuted the orangutan into charcoal.

"I know" Xiao Yu replied as he looked at the group of orangutans attacking the city wall, and then the blue phantom disappeared.

There are 500 mecha on the city wall, 300 of which are ordinary mecha and 200 mecha mixed with the flesh and blood of the Brondo scorpion, most of the mecha still have bullets, and the number of orangutan swarms is not much, about 2,000, the ratio is one to five, which is okay. Ye Tiantian thought silently in his heart.

With the help of the power grid, the range of octopuses was suddenly much smaller, and the dense torrent of bullets caused them huge casualties, but the weapons that were raised from the base next made them even worse.

A mechanical arm with a radius of five meters rose under the metal ball, and this mechanical arm held a hundred-meter-long sword, with electric sparks flashing on it, and the arm began to swing immediately after it was raised, and all the octopuses everywhere they went were electrocuted into charcoal, and there was also an electromagnetic force attached to it, as long as the octopus was within five meters of the electric blade, it would be sucked over.

For a time, the formation of the entire octopus school was scattered, and then it was completely overwhelmed by the torrent of bullets.

On the wall, Ye Yitian and the rest of the mecha are engaged in a hand-to-hand fight, these orangutans seem to be huge, but compared to the Brondo scorpion, it is really too bad, a punch down, can only make the mecha take a few steps back, if the Brondu scorpion swings in front of it, the mecha will probably be cut in half, and the attack speed of the orangutan swarm is very slow, it is easy to dodge.

Half an hour has passed, Ye Tiantian and Xiao Yu stood on the wall and looked at the base, although the attack power of the beast herd this time is not as good as last time, but the numerical advantage makes up for this shortcoming, the entire base is full of fires, the wall is full of metal thorns, fifty percent of the structure of the entire base has been destroyed, and the power grid and high-voltage electromagnetic blades have consumed huge energy, and now the uranium reserves of the nuclear fission reactor are not much, but in exchange for the corpses of a full 250,000 octopuses and 10,000 orangutans, In this way, although the flesh and blood of these mutated creatures were not as good as the flesh and blood of the beast herd last time, they were very large in number, which allowed Ye Yitian to squander them in a big way.

"Xiao Yu, I will give you all the permissions of the base now, and when the transformation system is completed, I will go to Mongolia." Ye Yitian looked at the burning base and said.

"Oh, I'll take care of the base." Xiao Yu looked at Ye Tiantian's back and replied in a sweet voice.

In the next few days, Ye Yitian and Xiao Yu cleaned the battlefield together, but one day, when Ye Yitian was cleaning the battlefield, Min Tianxing called and said that the code had been corrected.
