I Actually Had a Soft Meal with the System in the Prehistoric Times

Traveling through the prehistoric times, the system said: You can't practice, you can't fight, and you can't become a disciple. I asked what can I do? System: Lying down. I support you. I refused at first. Then the monster came and stood for a while - the monster died and I upgraded. Another night's sleep – another upgrade. System: Is it delicious? Me: ... This soft rice is really delicious. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
