I was extremely unlucky. After being struck to death by lightning, I actually entered a system. The system told me that I had to travel to different worlds to complete corresponding tasks and accumulate a certain amount of experience points before I could be reincarnated as an adult. Each world would have a certain number of opportunities based on the difficulty of the character. If all the opportunities were exhausted, I would never be reincarnated. Hey, why would my reincarnation be so unfortunate?
