Invincible from the Start

Su Heng traveled through time and became the invincible leader of the Demon Cult, number one on the Heavenly Ranking, and a world-famous demon. There is also a system that claims to spread positive energy, allowing it to do good things and save those believers who are still addicted to killing and unable to extricate themselves. The leader solemnly said that he would be a good person in the future and advocate harmony and friendship. The righteous people laughed to death after hearing this. Then, the demonic sect came to dominate the world... The believers asked the leader to wake up. The Righteous Alliance from outside has stormed the mountain gate...
