I Am the Number One Evil Cultivator in Xuantian Continent

Others have their own cheats when they time travel, but I have my own dialog box when I travel through time? The author at the other end of the dialog box calls himself "Toad" And I think Old Toad is more suitable for him. Bad news: When I came to this world, I found that I couldn't practice cultivation. Good news: Old Toad said he is the author and can give spoilers. (But I feel like he doesn't know much, but he doesn't know how to tell it.) Until I met the sealed old skeleton and I discovered that I could practice his skills. The old skeleton's technique is forbidden to be practiced in this world. Because Old Skeleton is an extraterrestrial evil spirit. But I discovered that I am also an alien demon. Since they are all, why can't they practice? In this way, under the pull of the two, the journey to another world began. And finding a way back to Blue Star.
