Opening Blind Boxes in the Demon World

Already completed the works "Martial Arts World" and "Zhenwu World"
This book is a fantasy and hot-blooded upgrade, also known as "The young master of the Demon Sect who traveled through time can only survive by opening blind boxes".
I thought I traveled through time and became the young master of the Demon Sect, but in fact, I traveled through time and became a beggar. I accidentally got into a righteous sect that could kill me at any time, but by mistake, I became the young master of the Demon Sect. Zong Fuli has nothing at all. He only has one maid, but this status brings troubles everywhere.
The only consolation is that my blind box can be opened in another world.
