Transcendent Immortality, Earth Traversal

"The times changed with each passing day."

Walking down the street.

Xu Zhi looked at the alien civilization of this planet. With each step, he crossed a thousand miles; the surrounding streets turned into afterimages, and the bustling sights poured into his mind. For the first time, he felt an unprecedented sense of reality.

People of flesh and blood, people he could touch, humans the same size as himself.

Schools, streets, companies.

Living here felt no different from living on Earth.

Their technological civilization was even undergoing an explosion of development and was somewhat more advanced, because the theories Xu Zhi had provided were the foundational technological theories of the Ixdar People.

"A beautiful river-system civilization."

Xu Zhi vanished from where he stood and sighed. "Though it has only developed for a few short centuries and has already undergone two Planet Environment Reforms, it has become another Earth, with its own atmosphere and liquid water."

Although most of the air consisted of extremely ordinary nitrogen, its oxygen content was only 8%. For humans, it was still a death zone with practically no oxygen, like the highest of high plateaus—and a high-radiation region as well.

But it was no longer a vacuum, and their bodies would not be torn apart.

Ordinary Earthlings could wear auxiliary oxygen masks and radiation-protection suits and live on this planet for a very, very long time.

"So Earthlings could theoretically live on this planet too?"

Xu Zhi looked up at the sky, his gaze flickering as he seemed to be thinking of something.

"You should go back and tidy up the room. Continue organizing the house; there's no need to follow me," Xu Zhi said to the young maid.

"Yes!"

She returned through the teleportation array.

After all, Xu Zhi was about to visit the sun.
