Rebirth of the Three Kingdoms: Training and Strengthening System

(Dear adoptive fathers, if your child wants to eat instant noodles, please give me a compliment.) Wang Yu was working out in modern times, and suddenly traveled to a small village with frequent wars during the Three Kingdoms period, and became a farm boy. When he felt confused and helpless, he activated the exercise-to-become-strong system. He could improve his strength through exercise and survive in this troubled world. Let's watch him experience all the way and compete with the heroes of the Three Kingdoms for world domination (note: there are many poison points and low poison resistance in the first 16 chapters that can be skipped, start from chapter 17)
