The capital of the Walker Guardians is a city with a very sci-fi atmosphere.

The city buildings here are very tall, most of them are towering metal towers. The tallest building is probably close to three thousand meters.

Previously, this location was protected by at least two large planetary fortress artillery groups and four medium-sized fortress artillery groups.

This is also the reason why Li Xin did not choose to behead the robot's main brain directly at the beginning of the war.

Before the planetary fortress artillery group was dealt with, the fleet got too close and suffered losses if they were not careful.

When all the planet's defenses were removed, for Li Xin, the planet's robotic mainframe was like a ripe fruit that could be taken off at any time.

The fleet approached the city from low Earth orbit, and Li Xin looked down from the huge warship.

The staff officer at the side said, "Sir, the intelligence we have obtained indicates that the Walker Guardian's main brain is located underground in the largest building."

"This sharp metal tower is actually the mainframe's external cooling system and antenna!"

Li Xin looked down as the staff officer said. The metal tower was at least three thousand meters high and had a sharp top.

I didn't expect that its real function is heat dissipation and communication.

Li Xin looked at it for a while and said, "Arrange the army to start airborne operations and completely capture the enemy's mastermind!"

"Yes! Sir!"

As Li Xin's order was issued, the large army landing ship began to slowly lower its altitude.

The hatch at the bottom opened, and large and medium-sized airdrop capsules were ejected from below to the surface.

It was another operation like dropping dumplings into the air, with thousands of airdrop capsules crashing into the city on the ground.

All the resistance strongholds in the city had been eliminated by warships using naval guns before the army airdropped.

Therefore, this airborne operation was extremely smooth. The ground troops quickly assembled and took their positions. Then, under the leadership of thousands of mecha troops, they began to attack the Walker Guardian's main brain base.

Along the way, countless robot sub-bodies, whether combat sub-bodies or working sub-bodies, were like crazy at this time, trying to stop the attack of human ground forces.

But this is undoubtedly wishful thinking. The space battle was lost, and the battle of the fortress artillery group was lost.

In the end, the capital's defensive buildings were demolished by naval artillery attacks.

It is undoubtedly wishful thinking to rely solely on the individual combat power of these robots to fight against human ground forces.

The mecha leads the way, and various laser cannons and plasma cannons can clear out a large number of robot sub-bodies with one shot.

Sometimes ground forces directly launch electromagnetic interference bombs, which can instantly burn out the electronic circuits of a large number of robots and paralyze them on the ground.

The ground forces advanced all the way and soon arrived at the location of the main brain.

They opened the mainframe's outer buildings and armored defenses, and the battle below began, and the mechas could not enter.

But the most powerful shock troops are still the genetically modified warriors, who wear power armor and are armed with chainswords or power swords.

In the underground tunnel, the robotic combat sub-bodies protecting the main brain were destroyed as easily as cutting melons and vegetables.

When the last gate collapsed, a huge robotic brain appeared before the ground troops.

It was a shocking scene. The soldiers walked out of the passage and saw a huge deep pit in front of them.

The pit is almost bottomless, and in the center is a giant body emitting blue light. Inside it, there are countless sub-bodies connected like cabins.

Circles of ripples are rippling, which is a manifestation of the huge energy gathering.

A psychic from the army came out. He looked at the scene in front of him and used his psychic power to sense the robot's main brain below.

The next moment, his face turned into surprise, and he murmured in disbelief: "Is this raising pigs?"

Because in his perception, around the huge body emitting blue light, there are living beings in all the small cabins connected by cables.

The brains of these living beings are wrapped in various electronic structures, and there are various brain-computer interfaces on their bodies and brains.

All living things are immersed in nutrient solution. Their bodies are basically motionless, but their minds are extremely active.

Obviously, all of their minds are running at high speed, and they may be living in a virtual world.

The psychics wanted to isolate the Mastermind's communications and command systems just as they had isolated the Legion Command Node within the star base.

But the next moment, an electromagnetic signal appeared in the communications of all the attacking forces.

Although most people can't understand it, psychics can still understand it.

This is the Mastermind communicating with humans:

"Alien organic invaders!"

"I am the Walker Guardian host node!"

"Please don't isolate my energy and communication systems!"

"My body holds the last of the Walker people. My mission is to protect them so they can continue to survive!"

"If you cut off my energy and communication system, these sacred races will die simultaneously."

"According to my underlying logic, in order to protect these sacred races, I will open my underlying system code and surrender to you."

"But... please don't harm the Walker people."

All the psychics who heard this were stunned. Did this mastermind surrender just like that?

However, whether it surrenders or not will not affect the outcome. But who wants to go through the trouble if it can save trouble?

The army's psychics were unable to make a decision, so the situation was reported layer by layer and finally came to Li Xin.

After seeing this news, Li Xin couldn't help but laugh and said, "This machine mastermind is really interesting."

"In order to prevent the deaths of the Walker people, we transformed them all into our own biological nodes."

"Now, in order to prevent us from killing these Walker people, they choose to surrender. This is really an amazing train of thought."

Weng Hua, standing nearby, smiled and said, "This isn't surprising. The underlying logic of robots influences their algorithms and choices."

"I think the underlying logic of this mastermind must include the need to ensure the survival of the Walker race."

"The former Walker tribe was apparently on the verge of extinction, so these Walker guardians suddenly became the main force of this planet, supervising and protecting the rest of the Walker tribe."

"I think that even though all the Walkers seem to be having problems in our eyes, perhaps their consciousness is actually living a very comfortable life in the virtual world!"

Li Xin nodded and continued, "Tell the commander on the front line to agree to the mastermind's request!"

"Control this mastermind as soon as possible!"
