In the third year after the spiritual energy was revived, strange creatures completely infiltrated human society. Exorcists, psychics, warlocks... All kinds of extraordinary professions are on the rise. Lu Chen was an ordinary three-card gambling magician on the street - until he awakened his strange talent "Switching the Sky and the Sun" during a near-death experience. The rules are simple: as long as he can complete a complete set of "techniques" (deception, misquotation, subcontracting), he can secretly exchange the cause and effect of any two equivalent things in reality. Bullets fired at him? Secretly change the end point of the projectile and let it shoot towards the enemy. A curse befell him? Secretly change the cause and effect object and let the curse caster reap the consequences. Others use strength to crush the world, but he uses tricks to deceive the world. "The law of cause and effect in this world... In my hand is just a king hidden among three cards. Guess which one is the real one?"
