Comprehensive Martial Arts: Critical Hits at the Beginning Will Be Returned Ten Times

As soon as I crossed the grassland, I was chased by a wild horse. After the system was bound, I was told that everything could be returned with a critical hit. If I hit a rabbit with stones today, I can save up a book of internal skills and mental skills by relying on ten times the critical hits tomorrow. The world's master breaks mountains with one punch and cuts rivers with sword? I'll start by beating up the wild wolves and see who can outlast whom!
