Lin Mu transmigrates into another world and becomes an adorable yet fierce little wolf cub that can only bark, “Woof, woof!” He even nearly ends up as wolf meat hot pot for a foolish emperor! Fortunately, he unexpectedly awakens a system that lets him rise to the top, obtaining the Spirit Pearl and Demon Pill from the immortal realm right at the start. While others practice swordsmanship, he drives cars; while others cast spells, he opens fire. As a wolf cub, he recruits the Marquis of Zhenbei, subdues the Valley of Ten Thousand Demons, and even makes the Sword God obediently serve as his carriage driver! The Great Zhou Dynasty wants his life? Lin Mu sneers. Once his Gatling gun starts roaring, even immortals will have to call their parents!
