The Pioneer spacecraft is ready to return, and these days, Su Yichen has sorted out some of the technology he has obtained from the base, including plant samples in the ecological balance circle and some valuable materials in the material warehouse, and brought them back to Earth by the Vanguard.

However, Su Yichen did not return with Lin Guodong and them, but stayed at the Pluto base. For this choice, Su Yichen was carefully considered, because according to the current position and orbit of Pluto, it happened to be in the direction of the route of the Southern Cross visitors, and he stayed at the Pluto base to use the advantages of the base to find out the real intentions of the Southern Cross visitors, and the other was to prepare the earth in advance.

Although it is not clear to what extent the technological civilization of the visitors from the Southern Cross has developed, and what their attitude is towards the civilization of the earth, it is far beyond the earth just from the fact that they already have curvature flight technology. Compared with each other, human beings on the earth are like children and strong men, once the other party does not have good intentions, the consequences can be imagined.

Su Yichen's stay in the base can also be used to contain Zuò, the Rand civilization is an advanced civilization in the galaxy, and the defense system of the Pluto base is extremely powerful, perhaps, it can use this to block the other party.

Su Yichen's decision was quickly approved by Earth, and of course Luo Yan stayed with him. In addition, Su Li, the Pioneer intelligent system, also stayed at the Pluto base, as a replacement, Luo Yan replaced the Pioneer with a new intelligent system with the help of the base system, although this intelligent system does not have the ability to evolve as human and intelligent as Su Li, it can be compared from the operating system and framework, but it is more suitable for the use of the Vanguard.

"All ready?"

Su Yichen boarded the Pioneer and inspected the materials brought back to Earth, especially the technology warehouse that stored the new intelligent system of the Zài Pioneer. After reading this, he came to the bridge. Lin Guodong, who was busy, hurriedly put down the work in hand and stood up from his seat.

"It's all set." Lin Guodong nodded, and then hesitated: "Chief, you really don't want to go back with us, or I will stay for you?" ”

"Hehe, there is no need to discuss this matter anymore, and besides, you can't replace me. Don't forget that I'm the one authorized by the Al Qaeda system. Su Yichen patted Lin Guodong on the shoulder and smiled, and then straightened his face: "The engines of the spaceship have been upgraded with the help of the base system, and according to the current maximum acceleration, the time for your return trip will be shortened by half." So you have to remember that there is still one year left after returning to Earth, and this year is very precious. Also, tell the Chief on my behalf that I will try to buy time for the planet here, and even ensure safety. But in the universe, the Pluto base is not omnipotent. I can't guarantee how much time and what the outcome will be, if ...... I said yes, what if! If the Pluto base really can't stop the other party, then the future is up to you. ”

Lin Guodong nodded silently, Mo Liwen and the others also understood the meaning of Su Yichen's words, and their mood was inevitably a little heavy. The universe is different from the earth, the entire universe is three-dimensional, and although the Pluto base has a strong defense force, the problem is that it is not a spaceship of the Rand civilization. It's just a monitoring base.

In the three-dimensional universe, even if the Pluto base happens to be in the way of the other party. But it is not difficult to bypass the Pluto base and continue to advance towards the solar system. Once the other party really has bad intentions, they can completely avoid the range of Pluto's base defense force and continue to move forward from the vast universe in another way. This is a very simple matter for a cosmic civilization that already has curvature technology, and it only takes a few more days.

However, Su Yichen has already considered this issue, and the Pluto base is used as a monitoring base. Nature has its role. According to normal logic, as long as the visitors of the Southern Cross first discover the Pluto base in the process, they will definitely stay near Pluto, and even come to explore one or two.

There is a high probability that the other party will do this, as long as the other party does it. Then Su Yichen has a way to delay the other party as much as possible, and even use the Pluto base to take the initiative to attack once he finds out that the other party really wants to come, so as to avoid the loss of the earth's civilization.

Su Yichen didn't know how likely the attack was to succeed, but it was an opportunity anyway, which was one of the reasons why he had to stay here.

Stretched out his hand and shook hands with Lin Guodong, Su Yichen didn't say much, everything he wanted to say had already been made clear. followed by Mo Liwen, then Gu Chen, and finally Gao Jian. When he shook Gao Jian, Gao Jian's hands clasped Su Yichen's hand and said: "Don't worry, we won't let you fight alone, didn't you say it, we only need half the way back to Earth, I think it's only a year to come back and forth, Director, you wait for us for a year, and we will be together in a year!" ”

"That's right! We're still together a year later! ”

Lin Guodong and the others suddenly woke up, and their frustrated expressions instantly turned into firmness. Su Yichen did not object to their promise, smiled and nodded in agreement, and agreed to the appointment for this year.

The next day, the day Vanguard left the Pluto base. Everyone inside the Pioneer has already taken their places, and Lin Guodong, as the acting captain, has begun the final preparations.

The self-check of the new intelligent system is completed, sending out a message that the spacecraft is in good condition and ready to take off. At this time, Su Yichen and Luo Yan stood in the control room, looking at the three-dimensional image of the location of the Pioneer displayed by the base system in front of them.

"System, activate barrier."

When the final time came, Su Yichen gave the order for the barrier to be activated. The system replied after a second that the barrier had been activated, a technique that was activated to prevent the Vanguard from being discovered by the Hades and Starry Sky that had already flown away from Pluto. This barrier is not ordinary electronic interference, nor is it the kind of stealth technology on Earth, but uses a kind of electromagnetic wave to send a false simulation to the other side to disguise the Vanguard's return.

This kind of technology is very common in cosmic civilizations, just like controlled thermonuclear fusion technology is so common to curvature technology, it is just a small trick. But it works well, and with the current earth technology can't penetrate the barrier at all, it's best to use it at this moment.

After the barrier was activated, Su Yichen issued an order to teleport the Vanguard. A white light instantly enveloped the Vanguard, and in the blink of an eye, the Pioneer in the base was teleported to Pluto's low-earth orbit, and its location was the coordinates where the Pioneer arrived at Pluto and stayed.

"Start the engines and adjust the heading...... Return! Inside the Pioneer, Lin Guodong issued a command, the spacecraft engine began to start, and a few minutes later, the huge Pioneer began to rise in low-earth orbit, and at the same time adjusted the return route, and when the route was adjusted, the spacecraft engine began to gradually accelerate, and the speed became faster and faster, just like a white meteor from Pluto's orbit drew a beautiful arc, towards the center of the solar system, towards the earth.

Just as the Pioneer was about to fly out of the Pluto skyspace, Lin Guodong and the others received a farewell from Su Yichen from the Pluto base.

"Have a safe journey!" (To be continued......)
