Yuan Dou and his companions started the mission, but what they didn't know was that when they left the solar system, Og, who had been staying in the solar system incognito, also drove a flying machine to chase after them. A day after they arrived in the Centaur system, Og arrived and followed him as he set out to infiltrate enemy rear.

The aircraft that everyone is riding in has been specially treated and has a very strong concealment ability, but on the contrary, the flexibility of action and defense ability are greatly reduced, and it does not have the ability to counterattack, and does not carry weapons. This was a purpose-built aircraft for the mission, and the purpose was simply to get the team members to the target location. The aircraft did not disgrace its fate, and completed the infiltration mission well, and at the same time as the frontal war began, it took Yuan Dou and his party to the rear of the enemy, a war fortress similar to a space station.

The Everybody's Flying Machine nearly triggered the enemy's defensive alarm when it approached the War Fortress, and finally managed to reach the rear of the War Fortress with the help of a comet, and then with the help of the spaceship, everyone came to the vicinity of the War Fortress. At this time, it is necessary to rely on everyone's own strength to infiltrate the fortress of war. Everyone had a plan of action, and immediately changed into a mecha, turned on the optical stealth ability, and slowly flew to the war fortress. Upon arriving at the fortress shell, Chizumi went into action, his mech carrying a special breakthrough tool that could silently avoid enemy alarms and open an opening for them to penetrate. It's just that this process takes a long time, and Yuan Dou thought of Og's ability to forcibly teleport at this time, with Og here, there is no need to go through such a lot of trouble at all, and he can easily teleport to the interior of the fortress.

After a long period of work, Senju's physical and mental strength decreased dramatically. However, despite this, he managed to open the back door, and everyone broke into it only to find that it was only in the mezzanine of the fortress's shell, and it would take a long time to get inside. Perhaps by God, they stumbled upon a more fragile piece of equipment, a pipe that I don't know what it does, but it's easier to break through than a sturdy shell. The crowd immediately went into action, and Senju used a special puffing device to temporarily block the entrance, and then began to work, this time without taking too long to successfully cut through the passage. When the yellow liquid in the tunnel flowed out, it was like a coolant, not much, and there was still enough room for them to walk along. So, everyone immediately changed into simple costumes, put away the mecha and entered it.

Walking along the coolant pipes to the end, everyone came to a room, which was a working room, and the transparent pipes were constantly wriggling, and the energy was clearly transmitted in them. After discussing it, everyone immediately had an idea, and they decided to follow the transparent energy pipeline to find the core area.

A spider-like robot is glued to the outer wall of the pipe, and this robot can transmit information to them in real time, and everyone asks the robot to move through the cracks in the pipe, and they only need to be tracked outside. Leaving the room, the door of the room closed automatically, Yuan Dou took a look and found that there was no gap between the automatic door and the wall, and couldn't help but sigh that its technology was powerful. Walking along the passage, the crowd was cautious, but they did not encounter any creatures or enemies, which was unprepared and a little overwhelmed.

"Don't worry about that, we're going to run into enemies if we keep going," Mototo said, "just hope it's not too difficult to deal with then." ”

Yuan Dou's words were quickly verified, perhaps because the previous passage was the outermost part, so they didn't encounter enemies, but when they entered another passage, they would encounter robot guards floating around from time to time, as well as alien soldiers standing at key points. These aliens are dressed in black armor, with long tails showing from their backs, and are more than two meters tall, holding weapons similar to stun guns. But these are not powerful, the most powerful enemy encountered so far is the soldier with a melee electric fork, they are larger, the spear in their hand is not much better than the knight's spear, they are the elite who patrol around, and never appear alone, accompanied by ordinary soldiers, it is quite troublesome to deal with.

At this time, after a long time of groping, everyone had come to the second level of the fortress. As soon as they went upstairs, they encountered patrolling pikemen. The crowd hid in the shadows, and after seeing the number of enemies, they began to assign tasks. Seven people, there are five who can fight in this state, three Yuan Dou, plus Cheng Yin and Shi Han. The number of enemies was six, one pike-soldier, and five stun-gun soldiers. As soon as Yuan Dou summed it up, he said to everyone, "I'll deal with two soldiers with electric guns, Ye Xi will deal with that spear soldier, and you will deal with one by one, is this okay?" Except for Chiju and Rizono, who pouted, no one else objected, and then everyone waited for the patrol team to arrive at the location, and then suddenly appeared, and immediately acted like a sneak attack.

When the patrolling people approached, and sneaked up to a high place, there was just a platform for him to settle on, and he was on it, waiting for the patrolling people to pass by, and immediately jumped down, holding a small holy sword in each hand, and completed a beautiful assassination from top to bottom, accurately solving the two soldiers behind the elite soldiers. Then the others also emerged from other places, also in a galloping action, and solved the target in an instant. This sneak attack was like a simulation many times, and everyone worked together seamlessly, taking out the enemy in an instant, and at the same time removing the enemy's corpse.

Suddenly, just as everyone relaxed their vigilance, a pair of soldiers suddenly walked out of the opposite aisle, also a six-person squad, and they saw everyone at the first time. Seeing this, Yuan Dou put down the corpse in his hand and immediately pounced, compared to him, Lian Yan and Ye Xi did not fall behind, and followed closely behind, but Cheng Yin and Shihan were a beat slower, but it was this beat that almost alarmed the alarm. Yuan Dou and Lian Yan were left and right, Ye Xi was in the middle, the speed of the three was the fastest, and they had already touched the enemy in less than a second, and at the same time each rescued the enemy. Lian Yan and Yuan Dou each learned about a stun gun soldier, and Ye Xi killed the spear soldier alone. As for the remaining two enemies, they had already opened their mouths, and Yuan Dou even felt that the voice had come out of his throat. At this critical moment, it turned out to be Riyuan and Chizumi in the rear who reacted and shot one at a time, solving these two enemies.
