The Villain Starts with the Method of Absorbing Power

Because he tracked down the powerful, Qin Chuan was betrayed by the person he trusted the most! On the verge of death, he obtained the villain system and the power-absorbing method, and from then on he started to become an invincible enemy in the world. Buddhism, Taoism, and demonic ways are all my ways. God's will and devil's will are all my will. Ask me what my name is, it's either a Buddha or a demon. I will become a demon and the demon will conquer all sentient beings.
