The commander on the screen had a serious face: "The command center informed all the troops that just now we found the reaction of aliens who disappeared hundreds of years ago. Aliens are known to be conning towers for mechanical lifeforms. As long as all the aliens are eliminated, our war with mechanical life forms will be over. ”

"Right now, the technical department is analyzing the source of the alien waves. However, because there is not enough information, the Parasitoma troops that are on the ground have the highest priority to collect information on this mission. As he spoke, the commander clenched his left hand to his chest: "We can't miss this opportunity...... Humanity is immortal. With that, he turned off the communication system.

After the communication system was turned off, 2B clenched the 'White Contract' on his waist and said to 9S next to him, "9S, let's go over quickly!" Then he rushed towards the big crater.

9S looked at 2B, which was constantly speeding up, and had no choice but to follow.

It only took a few minutes for 2B to run to the side of the big pit. At a glance, this big pit is actually more than 20 meters deep, and the radius is about 100 meters wide.

2B grabbed Pod042 and jumped straight down, and after a few seconds 2B fell to the bottom of the pit, and she began to look around as soon as she stood still, but there was nothing left but the wreckage of a building standing in the middle of the pit.

Just as 2B was looking around, there was a sound of landing behind her, and when she turned her head, she realized that it was 9S rushing over.

After 9S landed, he complained to 2B: "It's really ~2B, don't be in such a hurry." Then he looked around and saw the wreckage of the building standing in the middle.

9S looked at the wreckage of the building in the middle of the pit and thought to himself, 'This thing looks like a tombstone from a distance.' ’

He shook his head, shaking the thoughts out of his head. Then he looked to the edge of the pit, where a large part of the ground was missing, and from where it was possible to lead further down. He walked to the edge of the gap, and when he looked at it, he found that it was about ten meters deep. Turning to 2B, he said, "The aliens should be hiding under here." ”

2B walked over, and after hearing 9S's words, he grabbed Pod042 and planned to jump straight down. 9S next to her hurriedly grabbed her, and immediately said after seeing 2B's puzzled eyes: "I think we should wait for the rest of the Jiye Army." ”

2B didn't think so, and planned to shake off 9S's hand and jump straight down, but the movement behind them stopped their movements. At the same time, they turned their heads to look behind them, and saw several strange mechanical lifeforms emerging from the earth. They are like earthworms, with a head that is a constantly turning drill bit, about several meters long.

Just as 9S and 2B were about to deal with them, they found that these 'earthworms' writhed and flew into the air. 9S and 2B looked at the new enemy, which had no jets or propellers, and its body was made up of a drill and many robot heads, but it was eerily floating in the air.

'Not true! '9S looked at the earthworms' and realized that a certain part of their body was not the robot's head, but a transparent sphere with yellow electric light flashing inside. 9S saw this, and if he didn't know that this was a weakness, then he wouldn't have to live. Say to 2B next to him, "2B, that transparent ball on their body should be their weak point, blow them up!" ”

2B nodded, pulled out the 'White Contract' and rushed forward, although these 'earthworms' can fly, but they don't have any long-range attack means, to attack 9S and 2B, they must fly down and attack with the drill on their heads.

So 2B just needs to keep an eye on their drills and cut those weak points when they fly down, and 2B sees the opportunity to use the 'White Contract' to penetrate the weak points after an 'earthworm' has attacked and before they are in the air.

The 'earthworm' that had been pierced through the weak spot disintegrated in an instant, leaving a drill and a bunch of robot heads on the ground. 2B took a minute to solve the 'earthworms' before turning around and walking towards the gap.

9S watched 2B's actions and knew that he had no way to stop 2B, and he planned to wait for the others to come and beat the boss together, but now he could only sigh deeply, grabbed Pod153 and jumped with 2B.

After a few seconds, 9S and 2B's legs stepped into the water, and the water that flowed down from the gap above accumulated into a shallow puddle here. Not far from them was a small robot that was sitting quietly, but this small robot was holding a torch in its hand.

After the small robot saw the falling 9S and 2B, he directly raised the torch in his hand and rushed over.

Although he has a torch in his hand, his combat effectiveness is not much different from that of other small robots, and 9S and 2B can easily solve it. After solving the problem, 9S and 2B looked at the huge passage behind it, and 2B did not hesitate and walked directly in.

9S followed behind 2B, and every dozen meters, you could see a torch standing next to the passage, and next to these torches gathered some robots, all of them holding torches, and there was a new enemy. The appearance of the new enemy is somewhat similar to the earthworms just now, and it is also composed of drills and robot heads, but the 'earthworms' have more than a dozen heads, and the new enemy in front of them has only one head, and there is a pair of small mechanical arms next to the head.

"This passage was dug by this kind of robot, and this passage seems to have existed for a long time." 9S looked at the little robots and said. 2B did not take up the topic of 9S, and after eliminating all the enemies, continued to move forward.

After a few minutes, 9S noticed that a metallic staircase had appeared in front of it, and there were many wreckage of robots on the stairs, which looked like they had rushed up the stairs and then been destroyed.

"The remains of mechanical lifeforms? It feels like it's been around for a long time. "9S looked at the appearance of these robots, and their bodies were completely covered in rust. This time 2B replied to 9S: "This is not what we should be concerned about, our mission is to kill aliens." ”

2B and 9S continued to walk up the stairs, and when they came to an iron door, 2B wanted 9S behind them to crack it. But I didn't think that this gate would automatically open after sensing 2B and 9S, and 2B looked at the open door and finally felt that something was wrong, as if aliens were waiting for them to come in. After passing through several automatic iron gates, 9S and 2B came to a circular hall with a circular platform in front of them, from where a staircase led to the next floor.

"This is ......" 2B muttered to herself as she looked around as her Pod042 came out to answer 2B's question, "I didn't find any information about this place in the database. "9S, who was following 2B, rolled his eyes when he heard Pod042's words: ', if there was information in the database, we would have found this place a long time ago.'

2B and 9S made their way down the stairs to the next floor, and before they could take a look around, a bright light appeared in front of their eyes.

Directly in front of the staircase, part of the wall of the rotunda suddenly rises, revealing its contents.
