Liu Xi traveled through a parallel world, only to find that this was actually the end of the world. Fortunately, Liu Xi had a system, so Liu Xi began his own end of the world...

While others were still worrying about survival, Liu Xi had already lived a comfortable life. While others were still searching for food, Liu Xi was enjoying a feast and picking up girls in his battleship RV.
