There is a strange school in the underworld of another world - Hell Academy. Here, every entrant will be forced to participate in the death game. Oh my god, it's too scary, you will die at any time if you can't complete the task! I'll go, no one I can survive! When everyone is terrified and desperate to survive, Jiang Yang discovers that the death game is just a simple copy that gives him unlimited experience and brainless equipment. Ding! Congratulations on the increase in yin and yang values... Yin-Yang Sacred Objects…
