A battle-hardened assassin transmigrates to a parallel world and becomes a national asset.
After comrades fall in the Battle of Purgatory, one begs him to look after his daughter, activating the Invincible Daddy System.
"What is this?! My God, I must be seeing things! The whole world has been hacked by a super hacker!"
"Our wife won't watch Where Are We Going, Dad? without us. Wow, Ling'er smiled! So sweet! I'm melting!"
"My father-in-law is so terrifying! Good thing I never messed with our wife."
"In my father-in-law's world, nothing is impossible!"
"The nation's father-in-law, the invincible daddy! Wow, Ling'er is so adorable!"
"No one gets to bully my daughter, not even me. Anyone else, even a god, would be wasting their time."
