After transmigrating to a cultivation civilization, he encounters a giant boar impervious to blades and bullets, and takes it down with a single RPG. A vulture? One shoulder-fired anti-aircraft missile does the job. A martial arts expert on the road? A heavy machine gun can turn him into a pile of pulp.
He has a lightning spirit root, but electric eels have gone extinct, leaving him unable to cultivate. Fortunately, he has science on his side, so he uses a generator to cultivate and advances by leaps and bounds.
If anyone tries to bully me with their higher cultivation, I'll have to bring out my scientific weapons. If a gun won't do, I'll use a cannon. If a cannon won't do, I'll use a missile.
And if none of that works, it's not as though I can't get my hands on a nuclear bomb.
The writing is very good and the subject matter is also very good.
