American Comics: Starting in Arkham, a System-based Batman

Wearing Gotham clothes, I was supposed to be deported, but how did I end up in Arkham? As he was being put into the police car, Zheng En was still optimistic. Although he had suddenly transmigrated to an unfamiliar place, being deported back home was better than staying in America, shooting guns. But something about the road seemed off. ...Wait, wait, wait, why does that building ahead say Arkham Asylum? At the same time, the crackling electrical activity in his head finally stopped. The system had finished loading, and a voice like a throat cancer patient rang in Zheng En's mind. He said he was Batman. Maybe I really should go to Arkham to calm down, Zheng En thought. The so-called system called itself a life simulator. Because the initial location was Gotham, it automatically loaded Batman as a mentor to guide him through life in Gotham. During this time, he was able to learn and acquire fragments of Batman's skills: martial arts master, linguist, firearms proficiency... And when Zheng En went to Metropolis, he loaded a new mentor: Superman. Steel body, cryogenic breathing, flight, thermal vision... Jung Eun: Wait, can these also be learned?
