After Awakening the Twin Guns, My Physique Will Become Invincible

[Killing beasts to become a saint] [Multiple female protagonists] [Double gun combination] [Strong body] [Super powers] As a member of the time traveler, I originally thought that I had just awakened an ordinary S-level spiritual power. Who knew that this spiritual power was actually a young lady, and she was very good-looking. Miss Lingwu can transform into two guns, one is an eight-foot spear and the other is a sniper rifle. Isn't this a combination of melee combat and long-range attack? But this is not all of the S-level spiritual martial arts abilities. Its attribute is that killing creatures can improve physical fitness, and it has dual attributes of thunder and fire. Tsk tsk tsk, is this one of the most powerful S-level abilities? Hehe... I won't be polite to ferocious beasts and monsters.
