Star Destroyer Cannon. Will It Be Used to Destroy Earth?

"Alien friend, can we meet and talk? "

 After talking to the electronic voice for a while, Zhang Tao wanted to observe the "alien" he was speaking to up close.

Naturally, Zhao Yu wouldn't let him have his way. Instead of showing up in person, he asked Big Sister Zhang and Brother Wang Er to send his captives to be imprisoned. While there were no prison cells built in this base, there were a few rooms in the industrial area that were fully equipped for Zhao Yu to live in temporarily when he was inspecting work. For now, he could arrange for the three of them to stay in the industrial area temporarily.

 Clang!

 The door opened, and the three of them took two steps back nervously.

Outside the door, a robot appeared. It was carrying weapons on its shoulders. It had a pair of emotionless laser eyes. It was the same robot that drove the three of them here.

The two robot guards didn't enter. Instead, they stood on both sides of the door. Then, two more figures walked in.

It was Big Sister Zhang and Brother Wang Er.

Looking at the two people who walked in, Zhang Tao and the other two were shocked. These aliens actually looked like them.

"You can take off your oxygen masks. You can breathe in the base!"

Big Sister Zhang's name was Zhang Yi Xia. She looked to be in her forties. She was a nanny designed by Zhao Yu in the early days when he first came to the moon. She was responsible for cooking and cleaning. The AI system implanted in her body was very human-like, and her expression was no different from a human's. She was so human-like, in fact, the three astronauts thought that they had encountered a living person.

Liu Ning glanced at Wang Dong Dong and Zhang Tao. Seeing them nod, she took off his oxygen mask. After inhaling and exhaling, she confirmed that the air was no different from Earth.

After Zhang Tao confirmed that there was no problem with the air, he extended out his arm and attempted to be friendly, "Hello, my name is Zhang Tao. I'm a native of Earth, the third planet in the solar system. I belong to the nation of Great Xia and am a member of Xia's space agency. I'm here because I'm carrying out the manned space exploration program…"

"Hello!"

Seeing this, Zhang Yi Xia shook his hand and asked, "Oh, so your planet is called Earth. What do you call this place?!"

 Zhang Tao and the other two were stunned. They could not believe it, but they soon realized that the alien they were speaking to wanted to ask them the name of the moon.

 "In the eyes of us earthlings, this place is called the Moon. Like the Sun, it's a celestial body that has always been with us…"

 "Are the two planets not far from each other?!" Zhang Yi Xia asked curiously.

Brother Wang Er's name was Wang Er Chun. He was programmed to have a quiet, shy personality. Seeing that Zhang Yi Xia was not stopping with her questions, he couldn't help but remind her.

"The butler doesn't want us to say too much!"

 Zhang Yi Xia stopped asking and spoke to the three astronauts, "Let's go. I'll bring you to your place of residence…"

"Butler?"

 Zhang Tao decided to remember this information. If possible, she would like to try getting more information from these aliens in the future.

 As they guided the astronauts to where they were going to live, Zhang Yi Xia and Wang Er Chun kept on whispering to each other. They seemed to be quarreling with each other. Meanwhile, the three astronauts looked around and followed them slowly. Behind them were two armed robot guards who watched their every move.

 After passing through a long corridor, they came to an elevator. Under the watchful eyes of Zhang Tao and the others, Zhang Yi Xia pressed the down button.

 Above the elevator, the numbers marked were changing from -9 to -10, -11… While looking at the numbers, the astronauts realized that this base was much bigger than it looked. Despite being obviously bewildered with all of this, Zhang Tao tried his best to remember everything he had seen along the way.

 "Ding ~~!"

Just as they were feeling nervous, the elevator door at -18 suddenly opened.

 "So, we are on the -18th floor?"

 "Let's go!"

 The elevator was huge, twice as big as the elevators on Earth.

 After entering the elevator, Zhang Tao saw that the two robot guards were also coming in. As heavy as they looked to be, the elevator did not tremble at all.

 Alien technology. Normal, right? Anyways, what shocked Zhang Tao even more was the number of elevator buttons inside the elevator. The numbers ranged from -1 to -180, meaning that there was a total of, what? 180 floors underground?

 The three astronauts were absolutely shocked. Without ever being found out by the humans, the aliens managed to build an entire gigantic structure under the surface of the moon.

"Which floor did the butler send them to?" Zhang Yi Xia stood in front of the button and asked awkwardly. In response to her, Wang Er Chun quietly pressed the button for the -109th floor.

Seeing that the -109 button light up, Liu Ning was a little scared, "Um, may I ask where you're taking us?"

 "Industrial area!"

 "Shua ~!"

As soon as he finished speaking, the elevator door opened. Looking at the top, the number had jumped from -18 to -109. 

That happened in a second. The three astronauts were a little surprised. When they looked outside the elevator, the scene had completely changed. At the -18th floor, there was a metal corridor outside the elevator. Now, as they were at -109 floor, they saw that there was a giant factory outside the elevator. There were mechanical devices operating automatically everywhere. The lights in the factory were shining bright. and the machines were all running on their own.

Not far from the elevator was a three-story iron villa. It was where Zhao Yu temporarily stayed when he was inspecting the work that took place here.

Zhang Yi Xia said as she brought the three of them to the front of the villa, "You guys stay here. I'll come and deliver your daily necessities every day…"

 Wang Er Chun interrupted, "This villa is the only place you can move about. If you leave, these two won't show you any mercy!"

 As he spoke, he pointed at the two armed robots.

 "Yes, understood! We won't run around!!" Zhang Tao quickly agreed, then brought his two subordinates into the villa.

 ..

 "Has the star destroyer cannon been built?!"

 "Yes!"

 "Let's go take a look. It's taking all my time to deal with these captives! I need to go see my star destroyer cannon!"

 Zhao Yu took the elevator and went straight to -5 floor. On this floor, there were all kinds of defensive weapons waiting to be activated from their dormant state. Zhao Yu didn't stop here when he arrived. Instead, he boarded a small train on this floor and headed elsewhere.

 After about three minutes, the train stopped at a place that looked like a rocket launch station.

 "This is the star destroyer cannon?!"

 Zhao Yu was overjoyed as he saw the cannon muzzle that was hundreds of meters tall. The star destroyer cannon was the most powerful weapon he had at the moment. According to the system, the highest-level star destroyer cannon could blow up a star. Of course, the level of his cannon was still far from being able to do that. Right now, it was a level one cannon, and it could blow up a celestial body with a diameter of no more than 100 kilometers.

 "The ground here has been disguised as a volcanic crater. If necessary, we can send the star destroyer cannon into space through the flying device at any time…"

 "Can we do a test fire now? "

 Zhao Yu was eager to give it a try. Like what he did to all his other weapons, he wanted to test his star destroyer cannon 100,000 meters underground.

 "Sir, the power of the star destroyer cannon is a little too much. Our shooting range might not be able to withstand the impact…"

 Uncle Da hesitated for a moment, "...Why don't we go outside and test it out? It just so happens that these aliens came from a place called Earth. According to the information on their spaceship, Earth is only 380,000 kilometers away from our base. We can fire a shot there to see the effect…"
