"What coordinates?"

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

"I don't know." Su Yichen didn't understand what the coordinate position Yifan showed him was. After thinking about it, he mobilized the intelligent system of the Pioneer to query the coordinate point, but soon the query result of the intelligent system told him that there was no problem with the coordinate.

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

A few days later, the Pioneer spacecraft successfully flew over Mars, and the earth was ahead. In space, the blue color of the earth is so charming. Standing side by side with Luo Yan on the bridge, looking at the earth that is close to you, my heart was filled with emotion.

"Finally back!"

Su Yichen said softly in his heart, I don’t know how Lin Dong is doing now after leaving the past few years. And his colleagues at the 781 Center, the closer they are to home, the more Su Yichen misses her.

When he was about to arrive on Earth, the Earth Space Fleet, which was notified, confirmed and contacted the Pioneer. Through communication, the Pioneer quickly cut into the Earth's low-Earth orbit. After running around the track for 11 circles, the Pioneer landed on the ground according to the procedure. When the Pioneer landed, it was like a meteor passing through the air. The American continent, the European continent, and the African continent passed one by one below the Pioneer. After crossing the Himalayas, known as the roof of the world, the Pioneer landed at the location of the Pioneer. Under the guidance of the ground base, the huge Pioneer was like an alien who split the clouds and mist, descending from the sky to the northwest base.

When 8,000 meters above the ground, the controllable thermonuclear fusion engine was turned off and the auxiliary engine was started. The huge Pioneer lowered the altitude rhythmically and finally stopped steadily at the venue prepared for it.

As soon as the Pioneer landed, the base personnel who had already prepared a long time ago arrived in a car. On the one hand, they were welcomed to the Pioneer return to Earth, and on the other hand, they were to prevent accidents during landing, and to do a good job of rescue and repair at any time.

The person who came to welcome Su Yichen on behalf of the base was his old acquaintance, Li Chen, who was the controllable thermonuclear fusion group back then. He is now the head of the 781 Center's 863 research base. He also takes into account the chief engineer of the physics research room.

The gangway of the spacecraft opened, and Gao Jian was the first to come down. When Gao Jian came down to the ground, Su Yichen and Luo Yan appeared in front of everyone.

"What a big formation." Holding Su Yichen's arm, Luo Yan saw the guard line surrounded by hundreds of live ammunitions around the Pioneer spacecraft, and couldn't help but sigh.

After all, Luo Yan was hibernating when she left the earth. Although she had been to the Northwest Base, of course, she had never seen the security level of this base because of her situation. Moreover, food poisoning occurred in the Pioneer spacecraft before the first takeoff of the Pioneer spacecraft. Since that time, the guard status of the entire base has become more stringent. Now they are returning to Earth, the base takes the security measures for the Pioneer spacecraft and people, including them.

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

"Director Su!"

Seeing Su Yichen, Li Chen walked forward with an excited expression and stretched out his hands to him from a distance.

"Old Li. I haven't seen each other for a long time." Su Yichen shook hands with him vigorously and asked him with a smile how good he had been recently.

"Okay. Everything is fine, but we don't know if you are not in our hearts. You are back this time. I want to ask you for advice if you have some questions."

"Let's make progress together, what else can we talk about to ask for advice?" Seeing his old friend, Su Yichen felt relieved and chatted with him happily.

Then, Li Chen noticed Luo Yan standing beside Su Yichen. He hesitated for a moment and soon recognized who Luo Yan was, a little surprised and said excitedly: "Teacher Luo? You...you are so young now! I almost dare not recognize you like this."

Luo Yan and Li Chen were also acquaintances who had worked together. They immediately smiled and shook their heads, shook hands with him and made a few remarks. Then Li Chen told Su Yichen that the car they picked up were coming, and that they were tired along the way, so they had a good rest for a few days before talking about work.

"Wait, there are still people." Su Yichen turned around and looked at it. At this moment, Su Li's figure was also exposed from the hatch door. Su Li, dressed in a little girl, jumped and ran down the gangway.

"Is this..." Seeing Su Li appear, Li Chen was stunned because in his memory there was no such girl who went to Pluto. How could this girl return to Earth with Su Yichen and the others on the Pioneer spacecraft?

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

Li Chen felt that the name Su Li was familiar at the first time, and then he recalled it, and soon a look of astonishment appeared on his face.

"You...are you..."

"Okay, let's talk about this later. Lao Li, where are you going to pick up our car? Where?" Su Yichen winked and stopped Li Chen from almost shouting. After all, this is not the place to talk about Su Li's origin. After Su Yichen reminded him, Li Chen suddenly woke up and asked them to wait. After leaving for two minutes, a dark RV soon drove over.

The RV brought by Li Chen is very spacious inside, with isolation glass in the cab and rear seat, making it very convenient to sit inside and talk.

Su Yichen and his wife got on the bus first, then Su Li and Gao Jian, Li Chen got on the bus finally. When the door was closed, the driver who had already received the order started the bus. The car drove out of the venue smoothly without stopping at the base and went straight east.

“Where are we going now?”

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

"The living area of ​​the base has been adjusted. In order to ensure safety, it is built in an area 25 kilometers eastward. Where will your residence and Teacher Luo be arranged for the time being." Li Chen explained, and Gao Jian, who was sitting next to him, nodded slightly to Su Yichen and the others to show that Li Chen's explanation was correct.

"It's been more than three years in a flash. I didn't expect that even the entire base would have changed so much after not coming back in three years." Looking at the appearance of the base skimmed by the car, Su Yichen sighed. This was the first time he had returned to Earth in the past three years, and this time he came back to find that the entire northwest base had changed too much, which was very different from what he remembered. He pointed to the new areas and buildings built in recent years, and Li Chen explained their respective uses for him. Su Yichen and Luo Yan nodded slightly while listening.

The Northwest Base has indeed changed a lot. It has become China's largest aviation base. Compared with Jiuquan Base, the scale of the Northwest Base has exceeded the scale. Now, according to Li Chen's introduction, two new spacecraft are under construction in the Northwest Base. If everything goes well, it will be completed in the first half of the year at the latest.
