The City Hunter's Supreme Bodyguard

Once, he stood alone at the pinnacle of the world, invincible beneath the heavens! Now he has sheathed his blade, gazed out at the sea, and retired to his hometown! His head is worth a trillion, yet no one dares claim the bounty! His smile is sinister, like the scythe of the Grim Reaper! Don't touch anyone close to him, especially his boss, who is also his wife. For her, he would raze an entire city! He is a legend of this world, a super hunter hidden in the city. He is Si Tian, the God of Mad War!
