The process of going back was also very smooth, although the distance between Mars and Earth was greater, but it only added a few minutes of flight time.

When the two returned to Earth, Cheng Yuan did not return to Anhe City as soon as possible, but directly let the spacecraft land at the space portal base in Donghai City.

"Boss, you're back. As soon as she saw Cheng Yuan and Guo Xiaolian walking down from the spaceship with a smile, Zheng Jia hurriedly walked over.

Looking at Zheng Jia's hurried appearance, Cheng Yuan asked with a smile: "What's the matter, I'm in such a hurry to come back?"

"The space portal is ready, and you need to preside over the next testing phase, I'm a layman. ”

Zheng Jia rolled his eyes, and then continued: "I called yesterday, it was the head of the logistics department named Ruan Zhongming, he wanted to ask some preparation questions about the Mars exploration plan, but we didn't have any preparations here. ”

Zheng Jia sighed for a long time, she was actually very curious about how Cheng Yuan was going to arrange it. Seeing that the state has already started to prepare, does it really not need to prepare for anything on its own side?

Cheng Yuan waved his hand, and said without worry: "Sister Zheng, don't you feel at ease about this matter, haven't you seen that Xiaolian and I have walked around Mars, we still need to prepare here?"

Zheng Jia was stunned for a moment, but she still asked uneasily: "Are you well prepared? Don't make any mistakes at that time." ”

It's Mars, a planet so far away that no one will ever talk about it in everyday life. Now that he finally has the ability to land there and survive there, no matter how steady Zheng Jia is, his mentality is a little unbalanced.

At this time, Guo Xiaolian took over the conversation, and she said with a smile: "Sister Zheng, don't worry, Cheng Yuan has built a big city there, and everything is available, I have taken a lot of photos and videos, and I will pass them on to you later, you will understand when you see it." ”

Zheng Jia's curiosity was immediately hooked by Guo Xiaolian, if she could, she would also want to go to Mars to have a look, but when she thought of the red planet in her impression, her heart became very entangled.

No, Cheng Yuan and Guo Xiaolian have been there, which shows that the situation on Mars must have improved greatly. I just don't know what the situation is.

Seeing Zheng Jia's entangled look of being curious and couldn't help but think, Cheng Yuan smiled and waved his hand casually: "Sister Zheng, if you want to watch it, go to watch the video with Xiaolian first, and I'll go with Zero to see the space portal here." ”

"Good. Zheng Jia was also polite, and pulled Guo Xiaolian to watch the video.

After the two of them walked away, Cheng Yuan said to Zero: "Let's go, let's take a look at the overall situation of the space portal here." ”

Although the spatial portals are large, their control center occupies a small area, and it is a three-story building, which is a standard T-shaped building.

The two of them came to a small three-story white building, where Zero walked in front to lead the way, surrounded by intelligent robots holding weapons.

Cheng Yuan walked all the way and nodded secretly at such an arrangement. Intelligent robots are undoubtedly very safe to use as security, and it is undoubtedly impossible to sneak in.

Led by Zero, Cheng Yuan walked through the passage and came to a metal gate.

Zero smiled at Cheng Yuan, and then pushed the door open. As soon as the door opened, the familiar sound of machinery running in the ears came to my ears.

It is a huge room, illuminated by incandescent lights at the top, and three rows of special desks occupy the center of the room.

There are no computers on these desks, just a thin crystal keyboard on top of it. The virtual screen is suspended about 10 centimeters from the desktop.

Intelligent robots were busy walking back and forth in the aisles, and Cheng Yuan could also see the slender metal fingers of some of the intelligent robots sitting at the desk tapping quickly on the crystal keyboard.

"No one here?" Cheng Yuan didn't look surprised when he saw this scene, just a little curious.

Zero shrugged his shoulders: "The space portal is not an ordinary thing, at present, except for you and me, no one has mastered this technology, so whether it is here or on Mars, the program maintenance of the space portal relies on intelligent robots." ”

Cheng Yuan suddenly, he nodded and agreed: "Yes, but in the future, we will also cultivate some talents in this area, after all, human beings are the main body of society." But at present, this is the best, and if you use intelligent robots, you don't have to worry about confidentiality. ”

Cheng Yuan doesn't mind passing on some of the technology, but the premise of the spread is that he has eaten enough.

Moreover, the space portal technology is also extremely dangerous, and it may not bring benefits if it is circulated, but it will also involve a lot of trouble.

"Sir, there are no problems with the spatial portal in Tokai City at the moment, when will we start the first teleportation test?"

After coming to the control room, Zero was also a little excited, although the space portal was fine, but the teleportation between Earth and Mars, that was the first time!

"There's no rush to this. Cheng Yuan glanced at the intelligent robots around him, and did not immediately agree, but walked to the central computer.

On the holographic display of the central computer, there is no complicated data, but a very direct and simple presentation of the status of the three spatial portals at this time and the indicators of each link.

Everything displayed on the screen was very normal, Cheng Yuan glanced at it a few times, and said to Zero: "You are responsible for the preliminary work of preparing for the test, but you also know that the space portal is so large, our test will definitely alarm many people, so it is impossible to close the test." ”

Cheng Yuan naturally wanted to conduct a test quietly and smoothly, but with the few giant portals outside, he couldn't be quiet.

Zero was stunned for a moment, and then said with some shame: "It's because I'm too anxious, this matter really can't be too casual, do you need to notify Mr. Zheng?"

Since it can't be tested directly, according to Cheng Yuan, it must be made public. This requires the involvement of the outside media and all parties.

At this point, zero can only be handed over to Zheng Jia or Guo Xiaolian to do. He is very, very human, even more human-like than some humans.

But in essence, he is still smart!

The most important thing is that he has never tried to receive people and things, and the only few communication partners are Cheng Yuan.

Cheng Yuan retracted his gaze, smiled, and said indifferently: "It's okay, I thought about starting the test directly like you at the beginning, but the space portal is too large." ”

Cheng Yuan was also very helpless at this point, but he didn't take it too seriously, after all, public testing also has the benefits of public testing.
