The Adorably Sweet Wife of the Holy Manifestation Lord Erlang Is Surprisingly Strong

【Married First, Fall in Love Later + System + Immortal-Mortal Romance + Combat】 My name is Yang Jin. I transmigrated and took on the role of Yang Jian. I’m invincible, and I’m nearly bored to death. Afraid I’d quit, the System opened a new instance and had me play the role of an obsessively devoted husband. I got married in a flash. My wife is adorable and works for the Demon-Slaying Bureau. She’s just far too weak. I gave her an Auxiliary System that can help her level up quickly! My sweet, absentminded wife has no idea that I’m the one sending all her System missions from behind the scenes... My name is Zhong Ruotao. I transmigrated to a high-martial world and became the second daughter of the Demon-Slaying Bureau’s director. My older sister is a sword prodigy, while I’m a total weakling. I have a System, but it told me I had to marry someone in a flash to activate it. If I wanted to get stronger, I had to take the plunge! I met Yang Jin on a matchmaking site. He isn’t an awakened, just an ordinary person. But he agreed to marry me in a flash! I’m so happy! Once I get stronger, I’ll protect my husband! 【Ding! Affection System activated!】 I stared at the screen, dumbfounded. The System had set Yang Jin as my target. But why is his affection level at zero? Does my husband not like me at all? Whatever~ My plan to win him over starts now! Content warnings: The main plot is urban romance and combat.
