Immortal Mayfly

On the day of Guo Fu's eighteenth birthday, he and his friends inexplicably traveled to the world of Taoism. I thought I could awaken some kind of powerful system and reach the peak of my life, but reality gave me a hard blow - language barrier, lack of food, and I almost starved to death. His friend also disappeared. On the way to find his friend, he discovered that this world can be practiced, and immortals are no longer just legends. ... A few years later, Taoist Mayfly's name resounded throughout the Taoist world and became a being feared by everyone. And his once innocent heart gradually became cold and ruthless between life and death.
