Simultaneous Travel: Ouyang Ke in the Doomsday World

Ouyang Ke got a system that allowed him to travel through time at the same time, but he wasn't happy! Because every world he traveled to was invaded by another world! This makes it impossible for the time traveler to use his foresight! Over time, he even discovered that the scene of doomsday appeared in the entire world! Is it a speculative trend, taking what you want in the chaotic doomsday world? Or should we fight against evil and bring peace to the world? Please "tune in" to Ouyang Ke's road to empire!
