The next day.

In Yinghuo City, the scheduled return time is approaching, and a group of researchers who will take the Yanhuang ship back to Earth have ended their research missions and gathered outside the interstellar port of Yinghuo City.

Outside the interstellar port.

Zhang Zhai is facing ten researchers who will stay behind, and behind him are a group of people who will return to Earth with him.

"Professor Lu, Yinghuo City will be left to you." Zhang Zhai said solemnly, facing the person in charge of the left-behind personnel.

After hearing this, Professor Lu smiled and said as calmly as possible: "Mr. Zhang, I am quite experienced in staying behind to build an alien city, so don't worry."

Zhang Zhai smiled when he heard this and looked at Professor Lu and the left-behind staff in front of him. This scene seemed familiar.

During the first moon landing, Professor Lu was also a member of the Moon Palace staff, and it was he who took the initiative to apply to stay in Yinghuo City this time.

But, after all, there is something different.

When we stayed in Yuegong City, we only had to wait less than two days for immigrants to arrive, and the distance from the earth was not that far away.

This time, the people who stayed in Yinghuo City had to wait for nearly a month before anyone would come here again. And here, the earth is just a dim light blue dot in the night sky.

Zhang Zhai saw that Professor Lu didn't say anything more and shook his hand tightly.

"Professor Lu, take care."

"Mr. Zhang, have a nice trip." Professor Lu was still smiling.

No more words were said to avoid the atmosphere of separation being too intense.

Zhang Zhai turned around and walked towards the interstellar port, followed closely by the returning personnel.

…

Outside the interstellar port, none of the researchers who stayed behind in Yinghuo City moved first. Everyone's eyes were focused on the departing figures of Zhang Zhai and others.

It wasn't until Zhang Zhai and others had completely entered the interstellar port and their figures disappeared from sight that the remaining personnel looked back.

At the same time, a strong sense of loneliness arose spontaneously, which was suppressed by the firm will of the people left behind.

Professor Lu took a breath, turned around, looked at everyone, and said firmly:

"Let's go and continue the research mission."

…

Yinghuo Interstellar Port, Mooring Room No. 1.

Zhang Zhai and a group of returning personnel had already entered the Yanhuang.

In the main cabin, Zhang Zhai has been restrained by a protective belt on a fixed seat.

Intense instructions and feedback began to sound.

"Prepare to launch Yanhuang and Zhurong."

"The ground command room understands and starts the countdown."

"10!9!8...3!2!1!"

"The spaceship starts taking off!"

Just like when they arrived, Yanhuang and Zhurong started at the same time, getting rid of the last hold of Mars' gravity, breaking away from the surface of Mars, and accelerating towards the universe.

In the picture of the holographic screen on the front side of the main cabin,

Yinghuo City began to shrink continuously until it finally disappeared.

"Yinghuo City wishes you a safe journey and welcome back again." Yinghuo City's intelligent control system made a final sound and returned control of the spacecraft to the spacecraft intelligent control system.

"The spacecraft breaks through the Martian atmosphere, targets the Earth, and continues to accelerate to the limit."

As the feedback sounded, Yanhuang and Zhurong left the Martian atmosphere at the same time and officially embarked on their return journey to Earth.

…

Ground, Zhaicheng Space Center ground control room.

When the return spacecraft began to take off, the atmosphere in the command room became increasingly tense.

All the ground personnel were paying close attention to the data feedback from Yanhuang and Zhurong, performing their respective duties and ensuring the stable navigation of the two spacecrafts.

A large number of media were still gathered at the back of the command room. At this moment, all the reporters were a little excited.

"...Zhai Shen's Yanhuang has successfully left Mars and is on its way back to Earth. Penguin News will continue to broadcast the entire journey of Zhai Shen's return to you, and we will welcome Zhai Shen's return together with you," a reporter from Penguin News said excitedly.

.

"...Just now, Yanhuang completed its liftoff and officially began its return to Earth. This Zhaicheng Aerospace manned landing plan is also officially coming to an end. Let us witness Mr. Zhang Zhai's return to Earth and witness Zhaicheng Aerospace's return to Earth."

A complete success of the manned mission to Mars." A reporter from a news channel reported excitedly to the camera.

"...Based on the time it takes to go to Mars, God Zhai will arrive on Earth in fourteen days... This is the first manned mission to Mars, and it is also the first time humans have actually set foot on Mars."

…

In the main urban area of ​​Zhai City, in the rest area of ​​Xihe Park, in Villa No. 1.

Zhang's mother and Zhang's father were sitting on the sofa, watching the live broadcast on the holographic TV.

Seeing that the Yanhuang successfully left Mars and officially embarked on the return route, Zhang's mother and Zhang's father heaved a sigh of relief.

"You think, why don't we go to Yinghuo City and have a look?" Zhang's father looked at Zhang's mother and suggested.

"Zhaicheng University doesn't care about it, and Mirage Technology doesn't care about it either?" Zhang's mother said angrily after hearing this,

"Besides, Xiao Zhai hasn't landed safely yet. It's good for you. Are you thinking of other things?"

"Then...are you going?" Father Zhang asked cautiously.

"...It's okay to go and have a look." Mother Zhang hesitated for a moment and then replied.

…

Time passes slowly.

After the Yanhuang and Zhurong accelerated to their ultimate speed, the return voyage entered a long and stable navigation stage.

Zhang Zhai also continued research on life sciences, genetic fields, and gravity simulation technology on the spacecraft.

Time passed day by day while Zhang Zhai was immersed in various studies.

Finally, more than ten days passed suddenly.

…

In the universe, on the earth-fire route, the Yanhuang and Zhurong shuttled rapidly in no particular order.

Yanhuang's auxiliary cabin, inside the No. 1 lounge.

Zhang Zhai woke up from his sleep and the moment he opened his eyes, he was completely awake again.

Getting up, Zhang Zhai walked towards the main cabin.

On the front side of the main cabin, the holographic screen shows the images captured by the Yanhuang's external camera equipment.

In the picture, the blue planet is clearly visible and very close at hand.

Zhang Zhai stepped into the main cabin, glanced at the picture on the holographic screen, and a smile appeared on his face.

Even though he is the 'Zhai God', looking at the earth that is getting closer and closer at this moment, he still feels a little remote and timid.

Withdrawing his gaze, Zhang Zhai did not stay in the main cabin for long, and walked towards the small canteen in the auxiliary cabin just like he had done for more than ten days before.

In the cafeteria,

Some researchers were chatting casually while eating breakfast.

Although they experienced a relatively lonely interstellar voyage for more than ten days, under the premise of a complete psychological intervention plan and return to the voyage, all the researchers were in good mood.

"Let's have breakfast as before." Zhang Zhai glanced at the group of researchers chatting with each other in the cafeteria, and found a seat at random to sit down.

"Mr. Zhang...Mr. Zhang."

Just like before, as soon as Zhang Zhai sat down, the holographic images of Academician Gan and Professor Hu appeared.

Zhang Zhai couldn't help but smile.

…

After a simple breakfast, Zhang Zhai went to the laboratory to continue research on genetic science and gravity simulation technology.

After more than ten days of research, he gained a deeper understanding of the genetic field and even had some ideas for optimizing human genes.

However, gravity simulation technology still has not made much progress, and tentative theoretical research on it has experienced countless failures.

Time passes slowly.

Finally, it was afternoon on earth time.

"Father, Yanhuang is about to enter the earth's orbit." A1's voice sounded.

Hearing the sound, Zhang Zhai nodded, glanced at a line of formulas on the manuscript paper, and stopped the deduction.
Chapter completed!
