Lu Qing traveled to the prehistoric world and thought he was about to reach the peak of his life.
But the reality is: he has none of the systems, cheat fingers, artifacts, etc. That normal time travelers have.
Thinking of hugging the thigh, the problem is that the thigh doesn't want him.
I want to practice cultivation, but my qualifications are mediocre.
Even his proud IQ doesn't seem to be that great.
Lu Qing has been beaten every step of the way since he time traveled.
But he still persisted and grew until the end of the prehistoric world.
