After Traveling Two Thousand Years, I Inherited Guanghan Palace

I traveled to the moon two thousand years later. Grandma's last words: "Guanghan Palace was built by our ancestors when they landed on the moon, and they spent their entire lives building it.

The company's project encountered difficulties again and could not progress. I could only negotiate in person... This novel and its characters are purely fictitious.
