Guo Zhenyu knew that at this point, he could only barely fight to a standstill with this robot. If there was anyone else to mess things up, he would at least have a layer of skin removed. He took out two high-explosive grenades from his space bag and threw them towards the door.

"Boom!"

The door that would bring countless reinforcements collapsed from Guo Zhenyu's explosion, blocking the entire place.

Seeing that the reinforcements were not coming for a while, Guo Zhenyu felt slightly more at ease.

Taking advantage of the fact that the strengthening pill provided by the system was still effective, Guo Zhenyu used his fastest speed and got into a fight with the robot.

And for some reason, perhaps it was because of the central system of those mechanical guards from before, its reaction speed and agility was actually higher than Guo Zhenyu after taking his medicine. Guo Zhenyu had finally used his secret weapon to suppress it, and originally, he thought he could quickly deal with it, but he didn't expect this robot to be so troublesome. Furthermore, according to logic, its fuel supply wasn't enough to support its continuous use of flamethrowers, so he didn't know what black technology this robot used, but the fuel seemed to be compressed, providing this killing machine with an endless supply of power.

"Bang!"

Guo Zhenyu was punched into the wall by the robot and immediately felt an excruciating pain in his stomach. He quickly focused the recovery abilities of the system on his stomach.

As for that robot, although it had been hit by Guo Zhenyu's attack several times, it had only lost some of its electrical circuits. However, this did not affect its attack. After all, the robot did not know pain nor did it know fatigue.

After these few attacks, Guo Zhenyu gradually grasped the attack pattern of this robot. It did not have any scale killing weapons, and could only rely on the laser guns on it to deal damage to people. However, these laser guns had limited range, once it left the effective range, the damage would be greatly reduced and it might even lose its ability to attack.

Therefore, it needed to continuously engage in close combat with others, using its extremely resistant alloy armor to kill the enemies.

This kind of fighting style reminded Guo Zhenyu of the anime that he watched in the Japan when he was young.

The robots over there were huge, but their equipment was limited. They also had ranged weapons, but most of the time they fought in close quarters.

Guo Zhenyu looked, the AT force field shield had more or less recovered. Now, he could take the initiative and attack, changing the AT force field shield into armor, and covering his entire body.

Guo Zhenyu wrapped the pulse current around the glove. Relying on his amazing speed, he pounced forward and smashed the robot's face with his fist that carried the pulse current.

The robot sidestepped the fatal attack, then turned around and kicked Guo Zhenyu away. Before Guo Zhenyu could land on the ground, the flame thrower behind the robot shot out a beam of fire, instantly shooting the robot in front of Guo Zhenyu. The robot threw another punch at Guo Zhenyu's body, which Guo Zhenyu sent flying at a faster speed towards the wall.

Just as he was about to hit the wall, Guo Zhenyu did a high difficulty maneuver in midair. He twisted his body and stepped on the wall with both feet, enduring the huge inertia.

He exerted strength into his legs, and with a leap, he flew towards the original direction. Like a bullet that left the barrel, the robot was unable to dodge in time and was interrupted by Guo Zhenyu's attack.

The severed hand on the ground spurted out smoke for a while and then stopped moving.

Although the robot was still moving, both of its hands were broken. To Guo Zhenyu, it was no longer as much of a threat as it was before.

That robot was not vague. It changed its form from a skull to a small laser gun. Taking advantage of Guo Zhenyu's unguarded state, it viciously struck Guo Zhenyu.

Guo Zhenyu choked from the blow. Although this laser gun was small, its power was like a heavy cannon on Guo Zhenyu's body. If Guo Zhenyu did not have the AT force field shield, he would have been killed by this robot.

Guo Zhenyu looked at the place behind him that was hit by this thing and couldn't help but break out in a cold sweat.

The surrounding walls that were originally only deformed from the fierce attacks of the two were now turned into liquid by the robot's cannon.

At this time, only Guo Zhenyu who was standing in the molten iron had an AT force field shield, which was why he was unscathed. In fact, was he really unscathed?

At this moment, Guo Zhenyu felt as if his soul was about to be fiercely shaken, his entire body was trembling uncontrollably.

This robot was simply a standard war machine!

Guo Zhenyu was shocked.

"System, how can I defeat it?"

Guo Zhenyu asked.

"Such technology, with the host's current abilities, is undefeatable. But our host is calm and has learned how to use science to solve the problem."

The System spoke without thinking, leaving Guo Zhenyu completely stupefied.

"A scientific method?"

Guo Zhenyu mumbled. He was deep in thought, but he could not listen. After all, this war machine was still chasing him.

"Zi"

Suddenly, a laser beam shot out from the robot. Guo Zhenyu was unable to dodge in time, so he could only cover himself with a piece of metal that was as smooth as a mirror. Suddenly, the laser beam bounced off to the side.

So that's how it was!

Guo Zhenyu finally understood the mystery behind this, using the power of science to defeat it!

"System!" I want to exchange for a laser refractor! "

Guo Zhenyu shouted.

Then, a portable laser refractor appeared beside Guo Zhenyu. He held this device in one hand and maintained the AT force field shield in the other, quickly approaching the robot.

However, the robot did not discover the secret behind the attack. Instead, it charged towards Guo Zhenyu who was in front of it and used its laser gun to attack him.

"Boom!"

After a loud noise, the apparatus in Guo Zhenyu's hand was completely destroyed, and the robot also died under his laser gun.

"Phew, that was close."

Guo Zhenyu sat paralyzed on the floor, recalling what happened just now.

He almost died together with this robot. Luckily, he still had the AT force field shield on him, otherwise, he would have already become seventy percent familiar with it.

On a distant planet, in a research institute, Hoss's short and new assistant, Raul, said to him. His tone was filled with worry.

"Doctor, is that really okay?"

"According to the experiments that were carried out on this wild planet, if those lost experiments were to be used by the people of Savage Star, then I'm afraid that they would be caught by the law enforcement team of the universe."

Hoss tapped his fingers on the table and said with difficulty.

"But, will it expose our existence?"

Raul argued.

"Barbarian Star has long known about our existence. However, those weapons that surpass their civilization have to be destroyed and reclaimed. Otherwise, we will be imprisoned for three hundred years!"

After Hoss finished, he did not care about what his subordinate thought and left on his own.
