Rebirth of Technological Cultivation

Physicist Qin Fang was reborn into a different world due to an accident in an experiment, where everyone can walk on walls and have supernatural powers. But Qin Fang discovered that the technological level of this world was still in the steam age, and he started a cheating life since he had no talent for cultivation. Fly over the roof and walk over the wall? Are you faster than a bullet? What? You bet I don't have bullets in my gun? Feel sorry! My gun fires repeatedly.
