I'm Already Invincible, so I'm Here to Counterattack the System.

Bai Chen traveled to the world of cultivation and successfully relied on his own efforts to become the number one giant in the immortal world, but who knew that he was bound to a system that was 5,000 years later than him. I thought the system could be of some use. But Bai Chen was a little silent when he learned about the system's first mission... "Ask the host to successfully kill the arrogant and domineering Chu Yunfei within one year (qi training period)" Who? What cultivation level? Qi training period? Your system is quite funny. Thousands of realms: Qi training, foundation building, golden elixir, Yuanying, distraction, integration, transcending tribulations, and Mahayana. Central Heaven: Human Immortal, Heavenly Immortal, True Immortal, Mysterious Immortal, Immortal King, Immortal Saint, Immortal Emperor.
