Lin Yuan was accidentally bound to a "life simulator" and could choose a different identity to live a new life in each simulation. While others chose heroes, saints, and saviors, Lin Yuan took a different approach and chose villain identities such as "The Master Behind the Scenes", "The World-Destroying Demon Lord", and "The Lord of Chaos" at the beginning! He was once the Lord of Shadows who stirred up the storm, the Emperor of Darkness who made the heavens and worlds tremble, and he was also the God of Wisdom who led mankind to destruction. At the end of each simulation, he inherits all the villain's abilities, knowledge, and wealth, and affects reality. When the real world faces an unprecedented crisis and the right path is at a loss, the man who was once simulated as the "biggest villain" proudly arrives with the power and wisdom to subvert everything. He was once the world's enemy and now he's the only hope? Is he the savior, or the trigger for a greater crisis?
