Blue Files: the End with the Teacher

[Newbie, the writing is not good, please don't comment] (Non-teacher) Cheng Yifeng, who came back from school, was about to have a fun all-out battle, but was accidentally involved in Kivotos. There was an extra card in my pocket, and I also met with the president. After entering, I found that I had no halo or golden finger. The good news was that the teacher was here, but the bad news was that the teacher was here. "Blessed to enjoy" (Note: The writing is almost zero + updated from time to time, there may be some OOC, if found, you can point it out in time)
