Zhaicheng area, Zhaicheng Aerospace Headquarters, in the lounge on the top floor of the rocket building.

Zhang Zhai was half leaning on the back of the chair, with a window and a desk in front of him. On the desk were piles of manuscript papers full of formulas and data.

Through the window, Zhang Zhai looked at the Zhaicheng ecological area in the distance, across the river from Zhaicheng Aerospace.

After more than twenty years of living and reproduction, the entire ecological area has become a dense rainforest scene.

Inside, tall and thick trees stand with lush branches and leaves, blocking out the sky and the sun. Under them, various types of plants grow vertically and horizontally.

Animals crawl on the ground, birds soar above the rainforest, reptiles hide deep under the soil, and fish swim in the rivers.

All things thrive and reproduce, and the ecological cycle in the Zhai City area is thus stable and independent.

I glanced at the vibrant ecological area, and then looked further away. It seemed that the main urban area of ​​Zhai City had not changed much over the years.

Zhang Zhai withdrew his gaze and looked directly in front of him at the system interface that had been awakened.

"Host: Zhang Zhai

Wisdom:380

Popularity:124,451,121

Unlockable technologies: None

Technologies that can be unlocked in the next stage: None yet

Technologies that have been mastered: interactive holographic images, artificial intelligence, new energy reserves, three new materials, anti-gravity boxes, quantum supercomputers, short-distance space transmission technology, quantum communications, controllable nuclear fusion (residual), grand unified theory

A little inspiration, genetic optimization, ecological simulation, curvature engine."

Zhang Zhai's eyes paused slightly on the wisdom value column.

Twenty-five years have passed since the next phase of unlockable technology disappeared.

In the past twenty-five years, under the influence of large-scale population stimulus policies, the population of the entire human civilization has nearly tripled.

The popularity value gained by Zhang Zhai also increased significantly from this, and the wisdom value also gradually increased from the original 280 to the current 380 after consuming a lot of popularity.

"It's just a pity...the technology that can be unlocked in the next stage is still not available, even the word "temporary" has not been removed." Zhang Zhai looked down and looked at the two words "not available" immediately after the technology column that can be unlocked in the next stage.

He stopped again, shook his head slightly, and muttered silently to himself.

After scanning the entire system interface, Zhang Zhai closed it and withdrew his gaze.

"A1, Zhai Cheng's next destination is the earth, right?" Zhang Zhai looked at the image of A1 on the side holographic screen,

"Yes, father, it is expected that Zhai Cheng will arrive at the Earth's low-Earth orbit at nine o'clock tomorrow morning at geosynchronous time. According to the plan, Zhai Cheng will stay in the regional low-Earth orbit for a month."

Hearing this, Zhang Zhai nodded and said nothing more.

He got up and walked towards the bathroom.

…

After a while, Zhang Zhai, who had simply washed himself, lay on the bed in the lounge and fell into a deep sleep.

Outside the lounge, under the dome of the Zhai City area, the night is getting darker.

at the same time,

However, the outside world suddenly became excited because of Zhang Zhai's announcement.

Xihe official website forum, even though it is late at night when the earth is synchronized, there are still a large number of people gathered.

"...Ah, I miss Zhai Shen. I originally thought that Zhai Shen would show up during today's trial flight of the 'warp engine spaceship', but he didn't. Oooh, I can only hold Zhai Shen's doll and cry bitterly."

"I just want to say that the great God Zhai never thought that he would be able to see the birth of the 'curvature engine spacecraft' in his lifetime."

"There is nothing impossible. As long as there is God Zhai, there is nothing impossible!"

"Damn... Zhaicheng Space Center has issued a new announcement."

...The forum, which was originally noisy and lively, suddenly became quiet after several new announcements from Zhai Cheng Aerospace appeared.

Countless people gathered in the Xihe forum instantly rushed towards the homepage.

…

After a very short period of time, the Xihe forum became noisy again.

The entire Internet instantly exploded.

"Did I see it wrong? I must be hallucinating. Zhai Shen said he was leaving... really leaving, and he would leave for ten years."

"Uuuuuuuuah... No, Zhai Shen, don't leave, don't leave us behind."

"I'm a little confused. I feel... I feel abandoned."

"I won't play virtual reality games anymore. I'll start working hard to prepare for the exam from now on. I will definitely get into Zhaicheng University. Zhai Shen, please don't leave."

The news that Zhang Zhai will leave the solar system, leave humanity, and go to distant deep space spreads rapidly.

In a very short period of time, the atmosphere of the entire network has changed.

Sadness began to spread, and countless people couldn't help but be extremely excited.

In reality, on the earth, in interstellar cities on various planets, the lights of countless people turn on again, and countless people are woken up by their relatives and friends, and then they find it difficult to fall asleep again.

That night, countless people tossed and turned, unable to sleep all night long.

After nearly thirty years of the Zhang Zhai era, no one can imagine what the world would be like without Zhai Shen.

Countless people even have a sense of panic that the end is coming and they are left without a master.

…

Time passed slowly, even though the whole world seemed to be exploding, one night still passed by.

The next day, morning.

The Zhaicheng area, which was sailing in space, successfully reached the earth's low-Earth orbit.

Zhang Zhai also washed briefly and went to the interstellar port on the other side of the Zhai City area.

He planned to return to Earth to see his parents before leaving.

…

Outside the interstellar port, Zhang Zhai glanced at the somewhat busy interstellar port, then turned back to look at Professor Xue,

"... Come up with a complete plan as soon as possible and hand it over to the manufacturing area to start preliminary preparations."

"Teacher, don't worry. Although we are reluctant to let you leave, we will not deliberately delay the formulation and improvement of the plan." Professor Xue said solemnly.

Hearing this, Zhang Zhai nodded and said nothing more.

After briefly speaking to Professor Xue, he walked straight towards the interstellar port.

Behind him, Professor Xue watched Zhang Zhai's figure. When Zhang Zhai completely disappeared into the interstellar port, he withdrew his gaze and turned to leave.

…

A very short time later, the Jiuzhou anti-gravity spacecraft on which Zhang Zhai was aboard took off from the Zhai City Interstellar Port and began to sail towards the ground at extremely high speeds.

After breaking away from Zhai Cheng, which was already in low-Earth orbit, the Kyushu began its landing procedure.

On the front side of the main cabin of the Kyushu, Zhang Zhai, who was restrained by a protective belt on a fixed seat, looked at the approaching ground scene on the front holographic screen, and couldn't help but feel a little nostalgic and timid.

Zhang Zhai couldn't help shaking his head and laughing.

After completely leaving the ground at Zhaicheng Aerospace Headquarters, Zhang Zhai rarely returned to Earth.

Before this time, the last time he returned to Earth was half a year ago, when he came to see his parents who had fallen into hibernation in a human hibernation device.

Zhang Zhai's eyes were fixed on the ground picture on the holographic screen.

As the Kyushu continues to lower its altitude, the ground scene continues to expand in the picture.

First, there was the 'Gobi Desert' that had been transformed into grassland under the green space plan, then there was the 'deep pit' left on the ground when Zhai City was stripped off the ground, which has now turned into a vast lake, and finally next to the vast lake.

terrestrial interstellar port.

As the ground scene continues to approach, the height and speed values ​​of the spacecraft gradually decrease.

Finally, the Jiuzhou carrying Zhang Zhai successfully landed at the interstellar port.

The spacecraft hatch then opens, and the metal stairs extend from the bottom of the hatch to the ground.

After the rest of the crew exited the cabin one after another, Zhang Zhai also stepped off the spacecraft through the metal stairs and stood on the ground again.
Chapter completed!
