The Ultimate God of War

A young man transmigrates to a fantasy world. At the lowest point in his life, a chance encounter leads him to master a move called the Spiral Bullet. He later modifies and enhances it until it becomes his signature deadly technique.

The young man is full of righteousness and carries with him the modern ideas of Earth civilization, so he's bound to stir up all sorts of bizarre situations.

See how he fights the strong, aids the weak, upholds justice, and saves the world, and, of course, rescues beautiful damsels in distress along the way!
