Hmm... Actually, I didn't plan to write this book originally, but the two guys, Black and White Skull, said they wanted to calm down the guys below and let them know that not everyone can be the Lord of the Underworld, so I wrote it...
In fact, I don't think this is necessary at all. All the creatures in the underworld are dead, and I will not die. As long as I don't die, the underworld will never collapse. As long as the underworld still exists, sooner or later new creatures will come in...
Ps: The author Gao Yigou, the update speed will be very slow...
