Lin Shuyin, a senior girl in the Chinese Department, accidentally gets a strange collar, and after being forced to wear it, she realizes that the collar can't be removed, and that to unlock it, she needs to gather six core restraints in six different worlds: chastity belt, chastity bra, leg cuffs, arm cuffs, leg shackles, and handcuffs, and after getting and wearing them correctly, she can go back to the real world. Once the core restraints are worn, they cannot be removed on their own. The six worlds are: Urban Maze, Campus Prohibited Area, Wilderness Desperation, Dynasty Darkness, Xuanworld Trial, and Jianghu Prisoner's Path. Each time you travel, you will be randomly assigned auxiliary restraints, including but not limited to neck shackles, leg spreaders, gags, blindfolds, chains, tortoiseshell rope suits, etc. Will Lin Shuyan be able to travel to other worlds and successfully obtain the restraints and adapt to real life under the increasing layers of restraints? What will happen if she fails in her mission?
