In just a few minutes, Guo Zhenyu, who was collapsed on the ground, shot himself. Although his mind was in a mess from the experience of almost making a trip to the gates of hell, the door that blocked off the countless reinforcements had already been sealed. He clearly understood that there were only two consequences of staying here.

However, the door had already been sealed shut. This was a fact that no one could escape. Guo Zhenyu could only clench his fists and concentrate as he searched for an exit in the battlefield that was riddled with holes.

"System, scan the entire passageway. Let's see if I can find the exit."

The arena that could bear through a fight could not possibly only be the size of a palm. Relying on Guo Zhenyu alone, it was almost impossible for him to search the entire area within a short period of time.

"The scan is complete. No exit was found."

The results of the system's scan were obvious. If there was a place to enter, reinforcements would have come in long ago.

The system was of no use at all at this time. Guo Zhenyu was alarmed. Was he really trapped here?

No, not here.

Guo Zhenyu stood up and felt the surrounding walls with his hands. With his previous fighting experience, he was unable to break through this hard wall with his fists, but the cold and solid feeling did not seem to be able to wear him down. He touched every inch of the walls here, but he did not find anything special.

Who was Guo Zhenyu? If there was no exit, then he would create one even if he had to. "System, is there any way to break this wall?"

The system quickly answered, "With host's current ability, there's no way to break the wall."

The familiar answer given by the system made Guo Zhenyu furrow his brows, was he still not capable enough?

Guo Zhenyu punched the wall.

Although there was a loud bang, it was useless.

Guo Zhenyu raised his head, took a deep breath and closed his eyes. He knew he did not have much time, but he was still stuck in this feeling of powerlessness.

The battle between the robots was still fresh in his mind after he closed his eyes. The robots were also more powerful than him, and he could easily break them. Why was there nothing he could do to this wall?

A thought flashed in Guo Zhenyu's mind, he seemed to have grabbed onto something, the wall that he had no way to break, yet the robot could turn into molten metal with a single blast. Guo Zhenyu quickly ran to the pile of scrap iron that was left behind.

"System, is there any way to repair this laser gun?"

In front of that pile of scrap metal, Guo Zhenyu was not as excited as he was before it. He was very clear that the damage to the parts was not light, and they could not be repaired that easily.

"The damage to the core parts is relatively light, so they can be repaired by hand. The parts are seriously damaged and cannot be repaired."

The system gave him mixed answers. Guo Zhenyu was lost in thought for a moment. This method might not be feasible, and reinforcements could break into the city at any time. Time passed in a flash.

"Check the space bag, can you find the same parts or similar parts from the firearms you already have?"

Guo Zhenyu asked with a deep voice. This critical issue would determine the success or failure of this plan.

The System did not reply immediately, and was slightly nervous.

"Sixty percent identical parts, forty percent similar parts."

Guo Zhenyu heard the system's answer and felt very confident. Even though using similar parts would risk everything, Guo Zhenyu still intended to take a gamble.

He immediately began repairing the core parts.

Time seemed so long before he found a way to execute it. However, the moment he found a way to execute it, the time became extremely short. Every minute and every second sounded like the footsteps of a guard circling in his ears.

Guo Zhenyu didn't even blink as he stared at the parts in his hands. Any misfitting could easily cost him his life in the nick of time. Guo Zhenyu would rather die in battle than be killed by something he made.

When all the components were successfully installed, Guo Zhenyu couldn't help but let out a sigh of relief. The thing in his hand that looked like he was looking at a real person was actually that much.

Even if you had something in your hand, it would still be a technical matter to blow up a wall no matter where you were going.

"System, look for the most suitable spot to breakthrough."

Guo Zhenyu's hand was attached to the wall as he carefully observed. At the same time, he ordered the system to search the area.

After the System lost its effectiveness several times, it was finally able to show its usefulness.

Very quickly, Guo Zhenyu was able to determine the location of the breakthrough through the system's planning. He calculated the time based on his experience.

The time he had left to escape was very tight, and if he encountered reinforcements halfway along the way, it was very likely that he would lose everything.

Guo Zhenyu steeled his heart and shot out his laser gun towards the wall. In an instant, the huge recoil caused him to retreat a few steps, but even if he retreated a few steps, he was still unable to avoid the scope of the air blast. Guo Zhenyu immediately took out his force field shield and defended himself, barely escaping the attack.

After his vision cleared, Guo Zhenyu stood in the molten iron and watched as the hole was blasted out. He was very satisfied, with his own parts and components, the laser gun was even stronger than before. With this, he would not be in any danger even if he met an even more powerful robot.

Unfortunately, this satisfaction was only temporary. The loud explosion had already exposed his position. He could now run and see if he could run all the way out into the sky.

His strengthened physique allowed him to be much stronger than the average commando, but this was still far from enough. Guo Zhenyu decisively asked the system to exchange him for strengthening pills, and his speed immediately reached an astonishing level.

A fork in the road gave Guo Zhenyu more chance to live. As he ran, he wanted to throw the machine gun in his hand in another direction.

But after some careful thought, Guo Zhenyu revealed an enigmatic smile. He threw the gun to the side, thinking that he could use such an obvious method to slow down his movements, it was impossible for others to not notice.

Guo Zhenyu decisively threw the imitation laser gun in the direction he was escaping in. Even if they split their forces into two, it would still have a mitigating effect.

Without the laser gun, Guo Zhenyu's speed increased even further.

He was well aware of the fact that he had to focus on running at high speed. He ran as fast as he could according to the time set by the system.

However, in the end, humans were still inferior to humans. They had encountered a group of troublesome people. Rather than calling them humans, it would be better to describe them as monsters.

The three people standing in front of Guo Zhenyu felt very strange. Although Guo Zhenyu had machinery with him, but it was far from the extent that half of his body was mechanical. Guo Zhenyu was scared for a moment.

In just a few seconds of observation, Guo Zhenyu saw something familiar: an authentic laser gun.
