After an unprecedented catastrophe, human beings relied on a survival system called "trees" to survive on the severely polluted earth. The surviving humans used the catastrophe as a dividing point and called the period before the catastrophe the "prehistoric period."

I want to give you an eternal tree, which will accompany you for a long time instead of me, and support the last piece of paradise on earth for you and all well-intentioned human beings. ——Hevira
In short, it is a story about a domineering female technical emperor who created a system that will go down in history for her male crush.
Disaster Warning
1. Not in the present day, but the "prehistoric" non-modern time that the male protagonist travels back to also belongs to an era with more advanced technology.
2. Plot flow, the heroine Hevera
3. The author is a maniac who cuts outlines and edits articles, so he can only update from time to time. Little angels, please be careful.
4. Special! Don't! Correction! Affection!
