Parallel universes are supposed to "do not interfere with each other". An energy stone and immature means can turn things around and connect the spaces between the universes into a whole. Ji Chen enters another universe, and the world returns to the past and travels to the future. When he gradually gets used to it and even connects with people of different eras, everything returns to the original place, the original universe. Do all past events have to be cleared?
Intention: Never forget the original intention
