Mysterious Recovery: Sign in at the Post Office at the Beginning to Arrest the Spirit and Dispatch the General

My name is Lei Dong. When you read this sentence, I have been cheated. I was originally playing the King in the dormitory, but I was thrown into the post office! Do you know how cheating they are? On the first floor of the post office, give it to me, a newcomer who has just opened his eyes. The first letter was actually red. Fortunately, as a time traveler, I have a golden finger. It is a magically modified version of one of the Eight Magic Skills [Restraining Spirits and Dispatch Generals]. Able to change the original Qi into spiritual pressure. Okay, enough nonsense, I'm going to deliver the letter! Hope I can get out of this damn post office alive...
