I traveled to HP but I tied it to the wrong game system

Story of: I traveled to HP but I tied it to the wrong game system[This is my first time writing a long story, so I may not be very good, please forgive me!] (I wrote the main character, but you may not be able to tell that I prefer to write 0s that are like 1s) A poor passerby was accidentally killed on the street by the world maintenance of the Space-Time Administration. In order to compensate this innocent passerby who was tortured, the Space-Time Administration preserved his memory, sent him to the HP world, and gave him the identity of a wizard. 0025 "Don't worry, host, our Space-Time Administration will give you a complete life." Carl "Then why did you send me to the pre-war era, or the parent generation?" [0025 looking for information] 0025 "I'm sorry, host, we made a mistake, so I'll give you a game system as a replacement." Carl "Wow, what fun thing is this? It's something that can let me sweep away the Death Eaters and become an Auror again, right?" [Smiling] [0025 who received the farming system remained silent] Carl "Yes, right?" [The smile gradually disappeared] [HP has two male protagonists, and the CP is probably the St. Petersburg] [The cover is drawn by myself, it is Carl during school (●—●)]
