When Liang Feibai woke up, he found himself stranded on a deserted island with only a sign-in APP available on his phone. Others will get points and props when they sign in, and he will get monsters, devils, and all kinds of evil spirits when he signs in. On the first day of signing in, a century-old fox demon was released to suck his yang energy; on the second day of signing in, a thousand-year-old zombie was summoned to gnaw his brain; on the third day of signing in, even the ancient beasts came to accept him as their little brother. Other time travelers were thinking about how to escape from the deserted island, but Liang Feibai was thinking about how to make these monsters kill each other. He tricked the fox demon into PKing with zombies, tricked the ferocious beasts into fighting sea monsters, and watched a group of monsters and monsters fight in front of him in darkness. He lay under the coconut tree with his legs crossed and ate watermelon. Five hundred years later, when the strong men from the mainland finally discovered this forgotten desert island and prepared to "rescue" the poor man who had been trapped for five hundred years, what they saw was a group of monsters and monsters holding a sports meeting on the island. Liang Feibai was sitting on the rostrum, holding a microphone and shouting: "The next event, Thousand-Year Zombies VS Thousand-Year Dryads, a 100-meter race, begins!"
