He hadn’t even met his so-called “fiancé” when he found himself labeled as an “abandoned husband.” Discussing marriage had always been a sensitive topic for him, but he ended up falling victim to a cunning plot that involved marriage, dowry theft, and a seemingly arrogant “high and mighty” family. Those individuals who posed as “orphans” and “villains” wore sinister grins on their faces. They audaciously conspired against this young master, ensuring that peace eluded his family day in and day out. And now, what was this? The supposed “orphan” had suddenly transformed into a royal grandson?! Tears welled up in Lin Yuxing’s eyes as he exclaimed, “My love, let’s continue our days of togetherness!”

What kind of experience is it to travel through time and become an AI?

Li Wenyuan, who was hit by the meteorite, successfully experienced this feeling.

Fortunately, he discovered that the planet he controlled… seems to be a little bit special.

“Precious living metal? Any wall here is living metal!”

“Zello? You said that omnics don’t need this? Sorry, psionic machines are being produced.”

“Interstellar colony? Isn’t it good to build a ring world?”

This is a story of farming, and it is also a story of human exploration of the universe from the past.

There are space wars, interstellar adventures, civilization observations, and galaxy epics.

“So…” A few years later, facing the disaster that was about to sweep across the entire galaxy, the unmanned fleet controlled by Li Wenyuan stood up helplessly.

“They all think that I am a lost empire, and I can only do what the lost empire should do.”
