Warhammer: When I First Became a Gray Knight, the Demon Called Me Daddy

I, Su Mu, have traveled through time, but I am playing a super-realistic Sims game. You start as a [Grey Knight], and the system also gives you a [Spiritual Pet System]. Bite! Matching SSS-level initial spiritual pets for the host... Matching successful! [Spiritual Pet: Father of Plague·Kugas] [Quality: Mythical level (can grow)] [Characteristics: The decay of all things, the love of a loving father (loyalty to the host is permanently locked to MAX)] Before I could react, a huge demon covered in pus pounced on me and hugged my legs: "Dad!" Me: "???" Later, the system task asked me to purify chaos. As a result, the blood god Khorne came over with an ax in hand: "Father, whose skull do you want? I will offer it to you right now!" The Lord of Conspiracy, Tzeentch, unfolded the scroll: "Father, your fate has long been determined. All changes will be unified, and you will eventually be the king!" Me (collapsed): "No, I just want to play games quietly!" [System prompt: Congratulations to the host for winning the title [Subspace Group Pet], the favorability of the Four Gods of Chaos is +10086! The emperor's attention is +999! Looking at the crowd of big demons and primarchs calling me "Dad" behind me, and then looking at the black muzzles of the Inquisition's guns across the way, I felt numb.
