Upgrade in Another World and Become King in Reality

Zhang Yisheng was transported to another world just because he was about to be beaten and went out to relax. Fortunately, there is a way to return to the real world. Wait, why are there so many rooms? (This is not a weird rule! It's not a weird rule! There are rules, but they are not weird stories! The rules of each alien world are only used to describe the current situation in the alien world! The male protagonist is not a virgin! )
