"Tiger Roar, you hide in the dense forest by this river, if I can't come back in two hours, you go and leave the radio silent, and go back the same way with them. For two hours, I need you to be able to attract the attention of the clones when fighting breaks out in your neighborhood, and make them think we have a lot of reinforcements. Wu Tian said to the tiger roaring beside him.

"But I'm only one person, how can I make the enemy think that our reinforcements are expensive?" Tiger Roar asked.

"This is the river, and wild beasts will come to drink from the river, just grab a few goats and other beasts to seal their mouths and keep them from screaming, and then tie them to the trees behind the hillside. When you need to make a move, you only need to whip the goat with a rattan to pull the trees and shake them, so that the enemy will mistakenly think that we have a lot of reinforcements. Remember to set up an ambush behind the hillside, otherwise the beast's infrared signature will be detected by the enemy. After giving the order to the tiger roar, Wu Tian crawled from the bushes by the river into the cold and biting water. Well, for robots, the feeling of cold and biting is non-existent.

Under the cover of aquatic plants at the bottom of the river, Wu Tian cautiously crept and sneaked at the bottom of the dimly lit river, carefully avoiding the underwater camera, and following the direction of the river towards the location of the secret passage in his memory.

Because the place he chose at the beginning was relatively close to the secret entrance, Wu Tian didn't take long to come to a raised rock at the bottom of the river. As an escape route that is only used when escaping for their lives, the Fallen Scientist did not place electronic devices such as surveillance probes near the entrance. Because once this entrance and exit are used, it means that the base is no longer safe. In other words, it is possible for the enemy who comes to attack to take over all the surveillance probes inside and outside the base in advance by using electronic intrusion warfare. In that way, setting up a monitoring probe at the most secret entrance and exit is equivalent to exposing your escape route!

Fallen scientists could never have imagined that there would be such a thing as rebirth in this world. Therefore, the fallen scientist would never have thought that in his opinion, the most secret and safest escape route would instead become the most convenient passage for Wu Tian's invasion!

Wu Tian tiptoed open the flip cover of the mechanical lock disguised as a rock, and turned the password in his memory on the mechanical lock in front of him, which was like an old-fashioned turntable phone.

With the input of the last password, the mechanical lock in front of Wu Tian slowly opened. With the opening of the mechanical lock, the river water at the bottom of the river quickly washed into the open keyhole, giving enough pressure to the connecting rod in the mechanical lock, pressing the secret exit disguised as a riverbed rock at the foot of Wu Tian at the bottom of the river slowly opened to one side! Holding on to the rocks at the bottom of the river, he didn't let himself be swept down the channel by the river that was rushing towards the channel below, until the river was calm again, and then Wu Tian swam down the two-meter-square river bottom channel that appeared under his feet.

In the dark underwater passage, Wu Tian turned on the searchlight in the robot's helmet and projected a bright beam of light into the river in front of him. If it weren't for the fact that the robot was not equipped with sonar, Wu Tian would not have easily turned on the searchlight above the robot's head to explore the way. If it weren't for the fact that there could be no electronic sensors and cameras in this secret passage, Wu Tian wouldn't even dare to turn on the searchlight. Otherwise, a mere photoresistor can expose Wu Tian's whereabouts!

Sneaking along the underwater passage overgrown with aquatic plants, Wu Tian sneaked like a beast with his hands and feet. Gradually, the stone passage under Wu Tian's feet began to rise slowly. With this slow but steady upward trend, space gradually appeared at the top of the underwater passage that was not covered by stagnant water. And as Wu Tian continued to move forward, the water surface in the passage was also constantly falling. It wasn't until Wu Tian had advanced 3 kilometers that Wu Tian finally left the area covered by the stagnant water.

Turning off the searchlight, Wu Tian turned on the low-light night vision system attached to the robot's eyes. Considering that the enemy must have robots, mechas, and other enemies that cannot be detected through infrared detection, the low-light night vision device in night combat has become the most commonly used night vision device. Moreover, if you use active infrared detection or active radar, it will reveal the location of your robot.

Although the light in the passage was very weak, Wu Tian could still vaguely see the general scene in the corridor. Taking off the waterproof plug on the muzzle, Wu Tian held the electromagnetic assault rifle and cautiously groped along the front line of the right corner, while carefully guarding against possible traps.

Careful along the way, Wu Tian successfully bypassed three alarm devices in a row that could trigger the base alarm. Finally, Wu Tian came to the last mechanical combination lock of Yongdao. As long as he passed this mechanical combination lock, Wu Tian would be able to directly enter the sewer system of the underground base! Through the sewers of the base, Wu Tian will be able to reach the core area of the base!

However, there is a problem here, although Wu Tian knows the password of the combination lock, the other side of the password leads to the sewer! As a must-have facility at every base, there is not only sewage in the sewers, but also robots that are responsible for cleaning up the sewage! Although the robots that ensure that the sewers are unblocked, they are just ordinary robots, and they don't have the consciousness of a human like Wu Tian to live in them, but they are still very risky! Once Wu Tian, the intruder, is discovered, the robot in the sewer may be the first to sound the alarm! And once the alarm is sounded, Wu Tian's infiltration operation will definitely fail!

Therefore, the speed of this operation must be fast, and the communication facilities on the robot must be destroyed before the robot sends out the alarm!

Thinking back to this time of action, Wu Tian made sure that there was no mistake and opened the cover of the mechanical lock, toggled on the mechanical lock of the turntable, and entered the previous string of passwords upside down.

With a "click", the mechanical lock slowly opened. The well-camouflaged sewer entrance where the mechanical lock was located slowly slid to the side.

Just when Wu Tian was wading along the sewer to avoid possible robots and groping forward, ten kilometers south of the skirt snow mountain, in the lower reaches of the skirt horn river, a team of five one-star mercenary robots were looking at the data analyzed by the water quality analyzer.

"Although the sewage has been treated, it is still domestic sewage. Since there are clones here, the clones must have something to do with the groundwater and the river. It seems that the clone's living area must have something to do with the river. After reading the water quality analysis, the leader of the mercenary robot team immediately ordered, "Let's go upstream against this river to search!" ”

At the base of the snow-capped mountains, Dr. Chen, who was restless, had no intention of continuing to do research. Ever since the Dawning Empire's army was completely defeated by the Alliance forces, Dr. Chen had no mood to do research at all. At the thought that his terminally ill daughter might even be kicked out of the hospital because she couldn't afford to pay for her medical bills, Dr. Chen couldn't wait to rush out of this damn planet and go to the capital of the Dawning Empire, the Dawn Star, to rescue his daughter! But Dr. Chan couldn't do that. Once Dr. Chen is discovered by the enemy, there is only a dead end waiting for Dr. Chen! Because, in the Galactic Alliance's wanted list of so-called degenerate scientists of the Dawning Empire, Dr. Chen ranks third!

Unlike those scientists who try to use human cloning to achieve immortality, Dr. Chan believes that lifeforms, no matter how they are strengthened, are fragile. After all, no matter what kind of life form it is, it cannot resist the bombardment of artillery shells.

Rather than using human cloning to achieve the goal of consciousness transformation and eternal youth, Dr. Chen believes that liquid metal robots are the right research direction for immortality. Therefore, although Dr. Chen has a high position in the fallen Dawning Empire, Dr. Chen is a very unpopular outlier. It is precisely because of this that Dr. Chen will bring his scientific research team to the remote planet where other forces have less influence to build his own power.

It's just that now, in the face of the unstoppable search of the Alliance Mercenary Legion, Dr. Chen already feels that his time is running out.

As if confirming Dr. Chen's deep prediction that life has entered the countdown, the electronic device on Dr. Chen's right wrist suddenly emitted a crisp alarm sound!

The whole person spasmed violently as if he had been electrocuted, and Dr. Chen looked at the screen of the high-end micro-quantum computer on his right wrist in horror. On a rapidly unfolding A4-paper-thin screen, a robot in the sewer was destroyed before it could raise the alarm! When Dr. Chen tried to use his supreme authority to contact other sewer robots, Dr. Chen was horrified to find that all the robots blocking the path of the foreign enemy had been destroyed!

"How is this possible? How could the other party know about the secret base entrance that only I knew about? Dr. Chen gasped for breath, and layers of cold sweat quickly oozed from his forehead!

"No, I can't die, I definitely can't die!" Yelling hysterically, Dr. Chen quickly opened the communication channel inside the base and ordered sharply, "The enemy invades the sewers, and all the intruders must be killed!" ”

However, without waiting for the transfer of troops within the base, Wu Tian had already broken out of the sewers!

The core of the base is crooked, and the narrow passages that are only three meters wide and only two meters high are not conducive to the entry of large robots or mechs. Without the demolition raid of such a king of land warfare, even if the base were attacked by a powerful raid, it would have bought Dr. Chen time to rush into the sewers and escape. However, this setting did not have any obstacle to a robot like Wu Tian, whose size was no different from that of an ordinary person! Not only that, Wu Tian also used his strong individual combat power and relatively complex terrain to quickly shoot and kill the clone guards in front of him!
