The world view is similar to the existence of a parallel world. To put it simply, it is an infinite flow of dungeons. When you are pulled in, your hope of returning home is already slim. Of course, the insidious system will not let you know about this, and you can only be forced to operate and pass one dungeon after another. Not everyone will be pulled into the dungeon, only those with markings on their necks will be pulled in. If you have enough power, you can try to break the rules and force yourself out of control. However, the current success rate is zero, and you may not be able to find your original world yet, because the positions of the worldview are not static. They will change direction. If you enter by mistake again, the consequences will be serious.
Of course, the "gods" are quite friendly and will let you go back as long as you pass through twelve doors (one door represents a copy), but this is not easy. Normal people can basically only get through five.
Purpose: Mainly I hope everyone can get happiness from my novels
