Lu Chen, an ordinary college student, was accidentally bound to the Wanjie sign-in system. Starting from signing in at the Hall of Supreme Harmony in the Forbidden City to obtain the Holy Body of Chaos, he traveled through multiple worlds such as the world of cultivation, the wasteland universe, and cyberpunk. Signing in every day can unlock Hongmeng treasures and ancient magical skills. When Lu Chen signed in the "Original Tree of All Realms" tens of billions of years later, the system suddenly went out of control: "You have become the master of time and space, and it is time to fulfill the mission of unifying all realms."
It turns out that Lu Chen's blood is the key to the unification of all realms, and behind the system lies the ultimate game between the "Arbiter of Order" and the "Demon of Chaos". Can he break the fate set by the system and rewrite the fate of all worlds with the help of his partners? When Lu Chen used the sword of time and space to cut off the core code of the system, he found that he had already fallen into a reincarnation spanning tens of billions of years...
