Wei Xinyu was about to step forward and press the button of the secret door when a mecha robot appeared above his head, and he immediately quickly dodged to the other side of the sand dune to spy secretly. The mecha man landed in front of the secret door, and with a flick of the aperture of his arm, the button shot out a ray of light and hit the aperture of his wrist, and after docking the code, the secret door opened automatically, and the mecha man entered the underground passage.

Wei Xinyu knew that in order to enter the dark passage, there must be an aperture to open the door, and he now had to capture a robot to get its aperture to enter the dark passage. He was going to stay where he was, waiting for the next robot to arrive.

Suddenly, not far in front of Wei Xinyu's eyes, with a deafening sound of "rumbling ......" appeared, and then the metal frame buried under the ground slowly rose to the ground, and he was about to step forward to find out, only to see four giant robots falling from the sky, they formed a giant transport rocket next to the metal frame, sent the metal frame into the rocket cabin, and then flew into space.

Wei Xinyu was puzzled, he thought: [Where did they transport this metal frame? What is this metal frame for? ……】

"Don't move! Hands up! A robot said loudly with a gun against Wei Xinyu's back.

The robot spoke in Ross, which Wei Xinyu understood, and he raised his hands. Wei Xinyu turned his head and wanted to speak, but was held up to him by the robot with a gun:

"Don't look, don't play tricks, move forward."

Wei Xinyu raised his hand and obediently listened to the robot's command, and slowly walked forward. Guided by the robot's voice, they came to a secret door. After the robot's call to the underground command center, the secret door was opened by the control center, and Wei Xinyu was escorted by the robot into a dark passage.

The dark passage is very long and wide, you can walk ten heavy trucks side by side, and the entire dark passage is brightly lit, Wei Xinyu asked casually:

"What are you building such a wide secret passage for?"

"Let's go! Talk less and be honest. The robot said with a gun against Wei Xinyu.

At a corner at the end of the tunnel, the robot pressed a button in his hand, and a hidden elevator door was opened, revealing an elevator leading to the underground, and they quickly descended deep underground in the elevator.

Wei Xinyu took advantage of the slight relaxation of the robot in the elevator, twisted the robot's head off with a grappling hand, and quickly removed the signal ring on the robot's wrist, and quickly escaped from the elevator with the robot's automatic gun.

Wei Xinyu relied on the signal circle to pass smoothly in the underground passage, and he soon came to a large production workshop. It was the first time he had seen such a workshop, which was an assembly line, and many intelligent manipulators were busy assembling the accessories of the metal frame.

Wei Xinyu saw that there was no one in the workshop, and he ventured into the workshop to take a closer look at what the metal frame was. He came to an assembly line, only to see that only an ordinary metal piece is tens of meters wide and 1,000 meters long, such a metal bar cannot be seen anywhere, obviously it is a building piece, he thought:

"What do these robots want to do when they make such a big metal frame? Do they also want to build a space station? ”

From the outfits of these intelligent robots, it was obvious that they didn't need a space station, and Wei Xinyu couldn't think of the purpose of this giant metal frame when he stood in the empty space of the workshop.

As soon as Wei Xinyu entered the workshop, he was discovered by the robot in the control center, and the entire underground factory was like a big enemy, the robot sounded the alarm, and the robot guarding the factory was dispatched, and the first batch of more than a dozen security personnel rushed towards the assembly workshop of the metal frame.

Wei Xinyu and the robot started a fierce battle in the assembly workshop. With the cover of the assembly line's machinery and equipment, rich combat experience, strong physical fitness, and accurate marksmanship, he killed more than a dozen robots that came in first.

The robot commander of the control center saw Wei Xinyu's strong combat effectiveness on the screen of the control center, and ordered: to destroy the enemy who invaded the underground factory at all costs.

So, the second batch of robots entered the assembly workshop with bazookas and high-energy grenades. They were divided into three groups, the firepower was crossed, and they didn't care about the production equipment in the workshop, after they found Wei Xinyu, they immediately launched all kinds of light and heavy weapons in their hands at his body, bazookas, grenades and intelligent high-explosive bombs blew up the assembly workshop beyond recognition. When the smoke cleared, it was found that the uninvited guest who had trespassed into the assembly workshop had disappeared.

Wei Xinyu knew that there would be no good results if he fought endlessly with robots in the assembly workshop, and the opponent's extremely strong combat power made him dare not stay in the assembly workshop, besides, this underground factory was very large, and it was impossible to destroy it by his own strength, he thought: [The coming day is long, don't fall in love with war today, first find out the details of this underground factory, and then find its control center, eliminate the commander before leaving. 】

So, Wei Xinyu stealthily ran out of the assembly workshop, followed another underground passage, and came to another workshop, which was a parts production workshop.

Wei Xinyu took the underground maglev car, passed through several workshops in a row, he went in to see, they all came out immediately, he was in a robot manufacturing workshop, found that there was a control machine, there was a robot, a data cable was connected to the robot, and it was injecting the control program, he really wanted to change this control program and let these robots be used by him, but he felt that the time was not ripe, wait for next time. He went straight to the command center of the underground factory without stopping.

The commander of the underground control center was surprised by the sudden disappearance of the intruder, and wondered: [What is this intruder trying to do?] The workshops were safe and sound, and no intruders were found, so he ordered all the robots to strengthen their vigilance and guard the key roads at each pass.

Suddenly, the door of the control center opened, and the commander turned around to see that it was the intruder, who wanted to pull out a pistol from his waist, but it was too late, and he was shot dead by Wei Xinyu, and the two deputy commanders next to him were also killed on the spot.

Wei Xinyu quickly walked to the console and issued an order in the name of the commander: If the enemy situation is found in the assembly workshop, everyone must arrive quickly.

After Wei Xinyu gave the order, he turned his arm into a computer socket in the control center, connected the computer in the control center, copied all the data in the computer in his brain, and then removed all the grenades from the commander's waist, and blew up all the equipment in the control center, destroying the corpse.

The robot of the underground factory lost control and became a pot of porridge, Wei Xinyu returned to the dark passage in a maglev car according to the memory in his brain, walked to the upper passage, and finally returned to the original secret passage, when he opened the secret passage door and looked out, he couldn't help but shout:

"Wow, where are so many giant robots!"

At this moment, the pager on his arm rang:

"Teh, where are you? Where are you? When you hear the call, please answer! ”

It turned out that the pager on Wei Xinyu's wrist was blocked by the underground factory control center, and he didn't get in touch with the spacecraft until the control center was blown up and the secret door was opened.

Wei Xinyu replied with a pager:

"I'm in the robot's underground factory, and I'm now running out of the tunnels...... There are too many robots outside the cave, so I hope you can come and help. ”

Wei Xinyu sent a positioning to the spaceship, and soon the spacecraft hidden in the sand took off, and then the mecha on the spaceship was dispatched, staging a battle between the spaceship, the mecha and the giant robot of dangerous Mars.

The giant robot took advantage of its numerical superiority to attack the ship, and the ship flew towards the secret passage in a desperate way after destroying several giant robots in succession, and hovered above the dark passage. Thinking that the spaceship is going to invade their underground factory, the giant robots concentrate their firepower on the spaceship, and the mechs that block it outside fight fiercely against the giant robots.

Wei Xinyu seized the opportunity, jumped out of the dark passage, and jumped onto the spiral ladder of the spaceship, dense cannonballs bloomed on the spaceship, Wei Xinyu was almost hit by the cannonballs several times before entering the cabin, and finally jumped into the spacecraft cabin with a lot of effort.

Heng Liya saw that Wei Xinyu had safely entered the cabin, and increased her speed to fly the spacecraft towards space. In order to save Wei Xinyu, the spacecraft has been injured in many places, but fortunately, the spacecraft safely broke through the atmosphere of dangerous Mars and flew into space.

In order to get rid of the entanglement of the giant robots as soon as possible, Heng Liya played an energy bomb on the robots chasing behind, and after destroying several giant robots in a row, the robots chasing behind felt the power of the spaceship, and they did not dare to continue chasing, and the spacecraft finally escaped from the dangerous Mars and flew in the vast space.

However, after the spaceship was attacked by the giant robot of the dangerous Mars, it was already covered in bruises, and two of the dozen mechs that flew out were in the spacecraft that failed to return, and it seems that they have been buried on the dangerous Mars.

Heng Liya checked the energy consumption table of the spaceship, in order to hit the energy bomb, the spaceship had used up more than half of the energy, she said to Wei Xinyu:

"This time to investigate the dangerous Mars, our losses are too great, not to mention the destruction of 2 mechas, and the energy of the spaceship has also consumed more than half, I think our spacecraft can't continue to move forward, we must immediately turn back to the planet. Otherwise, we will be left in space forever. ”

Wei Xinyu shook his head and disagreed with Heng Liya's suggestion, saying, "We are all close to the planet we are going to, and it is not worth it." We can't afford to give up halfway and send a telegram to Earth, asking them to send a spaceship to DXQ2 to pick us up. We continued to fly forward, and this small half of the spacecraft's energy was enough to fly to DXQ2. Besides, the 001 and 002 miniature figures are waiting for us to rescue them. ”

Heng Liya knew that she couldn't resist Wei Xinyu, so she could only continue to fly forward according to his advice, and she hoped that there would be no more unpredictable situations on the road in the future.

However, after flying in space for three days, when it was about to reach its destination, the spacecraft was in a bad situation, the entire spacecraft lay down, the two space engines could not work, and the entire spacecraft floated in space. The spaceship lost power, so it could only drift slowly along the ship.

Wei Xinyu and Heng Liya were busy in the spaceship for a few days, looking for all the reasons, but the spaceship just didn't start. Heng Liya had no choice, she sent an emergency call for help to the earth planet again:

"The spaceship is in distress and floating in the air, please send the spacecraft to rescue it immediately."
