I Changed My Fate for the Four Beauties.

Su Tianhao inadvertently activates the copper hub of time and space that travels through ancient and modern times. The real bodies of the four beauties travel to the modern protagonist, take tasks on the spot, and go to the four major eras. The protagonist holds the time and space hub and can travel freely. The four people meet their death immediately when they land. The protagonist takes turns to rescue across time and space, paving the way for the rules of time and space, the backlash of cause and effect, and the long-term foreshadowing.
