[Stone Era] Weak JK Wilderness Survival

I am a weak JK who thinks "study hard and make progress every day". But one day all mankind was petrified, and all traces of mankind were silently erased by time. I was forced to start the experience of "wilderness survival". But fortunately, I hugged a strong thigh in time. The owner of the thigh is called Lion King Si! Intention: Study hard and make progress every day.
