I {Lin Chen} was cheated of my family property by my scheming sister-in-law and was falsely accused and imprisoned, but my fiancée Su Wanqing never left me. Activate the "Urban Sign-in System" in desperate situations and sign in every day to gain skills and resources. Sign in from prison to get "fighting skills" to beat down bullies, sign in to get out of prison to get "millions of start-up funds", and sign in to unlock the "devil-killing ability" when demons attack the city. The yandere school girl pestered me, and the scheming sister-in-law kept stumbling upon me, but I resolved them one by one with counter-intuitive operations. Su Wanqing's secret was gradually revealed, and it turned out that our fates had been entangled for a long time. When a handsome guy does things, he only cares about efficiency and making a comeback. Anyone who blocks my way will either get out or die!
