If I am no longer here, please fulfill the promise on my behalf. --Xu Sheng. " It's so weird that the writer of the letter has the same name as myself. When he looked away from the letter, a booklet appeared out of thin air where the envelope had been placed. I don't know whether it is official script or seal script, but there are three large dark red characters on the booklet. --"The Collection of Demon Solving". At this point, Xu Sheng embarked on a path of no return with the demon.
