"What coordinates?"

Seeing Ivan in the projection cut off the communication, Luo Yan, who had just walked in, subconsciously asked.

"I don't know." Su Yichen didn't understand what was going on with the coordinate location that Ivan showed him, and after thinking about it, he mobilized the intelligent system of the Pioneer to query this coordinate point, but soon the query results of the intelligent system told him that there was no problem with this coordinate.

"Strange ......." Su Yichen scratched his head, but quickly put the matter aside for the time being, because they were already close to Mars and were about to arrive on Earth.

A few days later, the Pioneer spacecraft flew over Mars, with Earth in front of it. In space, the blue of the earth is so charming, standing side by side with Luo Yan on the bridge, looking at the earth that is close at hand, my heart is full of emotion.

"It's finally back!"

Su Yichen said softly in his heart, I don't know how Lin Dong is doing now after leaving for the past few years, as well as his colleagues in the 781 center, the closer he is to home, the more Su Yichen misses it in his heart.

When it was about to arrive on Earth, the notified Earth Space Fleet confirmed and contacted the Vanguard, and communicated with the Earth Space Fleet, the Pioneer quickly cut into the low earth orbit of the Earth's space, and after 11 laps around the orbit, the Pioneer landed on the ground according to the procedure, and when the Pioneer landed, it was like a meteor passing through the sky, and the American continent, the European continent, and the African continent passed under the Pioneer one by one, and crossed the Himalayas, which are known as the roof of the world. The landing site of the Pioneer has finally arrived, and under the guidance of the ground base, the huge Pioneer is like a visitor from outside the sky splitting the clouds, descending from the sky to the northwest base.

At 8,000 meters above the ground, the controlled thermonuclear fusion engine is turned off and the auxiliary engine is activated. The massive Pioneer progressively lowered its altitude and finally came to a steady halt in the site it had prepared for it.

Wait for the Pioneer to land. The personnel of the base, who had been prepared for a long time, rushed by car, on the one hand, to welcome the Pioneer back to Earth, and on the other hand, to prevent accidents during landing, and to do a good job of rescue and repair at any time.

On behalf of the base, Su Yichen was greeted by his old acquaintance, Li Chen of the controlled thermonuclear fusion team back then, and now he is the head of the 781 Center in the 863 research base. At the same time, he is also the chief engineer of the Physics Laboratory.

The gangway of the spaceship opened, and Gao Jian was the first to come down, and when Gao Jian went down to the ground, Su Yichen and Luo Yan and his wife appeared in front of everyone.

"It's a big formation." Holding Su Yichen's arm, Luo Yan couldn't help but sigh lightly as soon as she came out of the hatch and saw a guard line surrounded by hundreds of armed PLA soldiers around the Pioneer spaceship.

After all, Luo Yan was in a state of hibernation when she left the earth, although she had been to the northwest base, but of course because of her situation, she had never seen the security level of this base at all, not to mention that there was also an astronaut food poisoning situation before the first takeoff of the Pioneer spacecraft, since that time. The entire base has become more tightly guarded, and now that they are returning to Earth, the base is also a matter of course for the Vanguard spacecraft, including them.

Su Yichen explained a few words softly, went down the gangway with Luo Yan, and soon saw Li Chen waiting for them.

"Director Su!"

Seeing Su Yichen, Li Chen stepped forward quickly with excitement, and stretched out his hands to him from afar.

"Lao Li. It's been a long time. Su Yichen shook his hand vigorously, smiled and asked him how he was doing.

"Good. It's all good, but you don't have a bottom in our hearts, you came back too timely this time, and I want to ask you for advice if you have a lot of questions. ”

"Let's make progress together, what else do we talk about?" Seeing his old friend, Su Yichen was in a good mood. I chatted with him happily.

Then, Li Chen noticed Luo Yan standing beside Su Yichen, he hesitated, and soon recognized who Luo Yan was, and was a little surprised. He said a little excitedly: "Teacher Luo? You...... You're so young now! I almost didn't dare to admit you like that. ”

Luo Yan and Li Chen were also acquaintances who had worked together, so they immediately shook their heads with a smile, shook hands with him, and said a few words. Then Li Chen told Su Yichen that the car they picked up them had come, and they were tired from the journey along the way, so they had a good rest for a few days before talking about work.

"Wait, there's someone else." Su Yichen looked back, and at this moment, Su Li's figure also emerged from the hatch, and Su Li, dressed as a little girl, ran down the gangway in a bouncing manner.

"Who is this......?" Seeing Su Li appear, Li Chen was stunned, because there was no girl of such a big age who went to Pluto in his memory, how could this girl be on the Pioneer spaceship and return to Earth with Su Yichen and them?

"Hee-hee, I'm Su Li." Su Li made a strange face at him and smiled happily.

Li Chen immediately felt that the name Su Li was a little familiar, and then he recalled it, and soon his face showed a look of shock.

"You...... Are you ......? ”

"Okay, I'll talk about this later, Lao Li, what did you say about picking up our car? Where is it? Su Yichen glanced at Li Chen and stopped what Li Chen was almost shouting. After all, this is not the place to talk about Su Li's origins, Su Yichen reminded him like this, Li Chen suddenly came to his senses, asked them to wait a while, and left for two minutes for a while, and soon a pitch-black RV drove over.

The interior space of the RV brought by Li Chen is very large, and the cab and back seat have isolation glass, so it is very convenient to sit in it and talk.

Let Su Yichen and his wife get into the car first, then Su Li and Gao Jian, Li Chen finally got into the car, and when the door was closed, the driver who had already received the order started the car, and the car drove out of the field smoothly, without stopping at the base, and went directly to the east.

"Where are we going now?"

Looking out the window, Su Yichen asked Li Chen, who was sitting opposite him.

"The living quarters of the base have been adjusted, and in order to ensure safety, it is built in an area 25 kilometers to the east, and the accommodation of you and Mr. Luo will be arranged for the time being." Li Chen explained, and Gao Jian, who was sitting next to him, nodded slightly to Su Yichen and them, to show that Li Chen's explanation was correct.

"It's been more than three years in a flash, but I didn't expect that even the entire base has changed so much without coming back for three years." Looking at the appearance of the base that passed by the car, Su Yichen said with some emotion. In the past three years, he returned to Earth for the first time, and this time when he came back, he found that the entire Northwest Base had changed too much, and it was very different from what he remembered. Pointing out the new areas and buildings that have been built in the past few years, Li Chen explained their respective uses for him, and Su Yichen and Luo Yan nodded slightly as they listened.

The Northwest Base has indeed changed a lot, it has become the largest aviation base in China, compared to the Jiuquan Base, the scale of the Northwest Base has been exceeded, and now, according to Li Chen's introduction, two new spaceships are under construction in the Northwest Base, if it is a qiē Shun lì, it will be completed in the first half of the year at the latest.
