Martial Arts Master

When I woke up from a dream, I was already in another world. With his unparalleled invincibility, he trampled all the geniuses and monsters from other worlds under his feet. With a sword, he slaughtered for hundreds of years, and finally set foot on the top of the continent! He thought he could break through all the restrictions and achieve the realm of immortality and immortality... However, in the end, he died and returned to the beginning. Is it an illusory dream? Or is it a dream that lasts for a hundred years?
