Jiang Chen received a letter from his sister the day before his birthday. It turns out that his parents are still alive, but trapped in a strange otherworld.
The silver coins attached to the letter belong to his sister, and she has reasons why she cannot appear in front of him now.
"... Xiao Chen, regarding your parents, I am already investigating. After tonight you will be an adult, and you will also begin to experience joining the world and survive in another world."
Jiang Chen casually threw the letter that seemed to be from his sister on the table. It was late at night and the clock that kept ticking was approaching 00:00.
Strange ceiling...
