The mc is about to jump off a roof because he is being crushed by debt after his parents died. Suddenly an immortal appears to save him and he floats midair instead of falling. The immortal says he should join an academy and gives him a letter of recommendation which we later learn is cause he is some super big shot. He also gives mc a system that requires him to bark 3 times in public to unlock it. If I remember correctly there was only 6 or so cultivation realms. The title was something along the lines of "I'm not actually an immortal cultivator" but I haven't been able to find it under that title or similar ones. I think the mcs name was han li or something like that
