Apocalypse King: Recruiting S-Tier Beauties With My Ruler System

[You Have Been Chosen.] When the apocalypse started, everything fell apart. I lost my job before they pushed me out into the street. Facing the undead, I became desperate and ran like a coward. Until I heard a voice... At first I couldn't believe the voice, thinking I might be insane and finally lost it... But as I was about to die, I saw a strange game-like panel appear in real life! [The Ruler System has activated.] This strange system let me gain points by killing zombies and the ability to recruit people as subjects who wouldn't betray me like my previous co-workers. My first subject? Mu Qinglan. The ruthless Ice Queen CEO I once called "Boss." Cold, untouchable... and now infected. As her bloodthirsty jaws closed around my neck, I barely saved her with the system’s makeshift cure. [Recruitment Available.] [Subject: Mu Qinglan (S-Tier)] [Press to Confirm.] A glowing button floated before me. I hesitated. Then, slowly, I reached out. [Recruitment Complete.] ▼ Mu Qinglan's attributes are now visible. + 100 Experience. + Leadership: Level 1 + Random Skill from Mu Qinglan [Rank Up!] ▼ Rank: Loser → Partner + Attributes Increased | Subject Cap: 2 Every subject I command strengthens me. Every kill feeds my dominion. In this world of death and chaos... I will build an empire of S-Tier Beauties and ascend as the Apocalypse King.
