Fantasy: Become Invincible by Adding Points by Killing Monsters

Traveling to the Cangxuan world where martial arts are respected, Gu Feng awakened the [Shadow God of War System]. Killing enemies can improve your cultivation, and your energy value can directly add points to your martial arts. It is better for others to practice hard for ten years than for him to kill monsters for one day. While others were still worrying about the bottleneck of their skills, Gu Feng looked at the system panel and fell into deep thought: "The energy level is full again. This time, should I improve my sword skills to perfection, or should I upgrade my newly learned movement skills to the full level first?"
