Pokémon: Infinite Ruins

The time travel was erased and the memory was sealed for thirteen years. When his memory recovered, he actually found that he had been digging in the ravine for thirteen years and was worthless, and he died like this? NO, obviously this is impossible. Fortunately, at this time, a guy named System resurrected deep in Ran Heng's memory. "You are very strong, can you defeat me?" "I'm sorry, my infinite ruins system has a small time travel once a week, a medium time travel once every two weeks, and a big time travel once a month. Divine beasts? Props? Skill learning machines? Hahaha, these are not problems, the problem is whether you can come out of the ruins alive!" This novel and its characters are purely fictitious.
