Can I Raise Su Huan Zhen’s Affection as a Villain?

Huh? Is this right? I opened my eyes and found I had transmigrated into Pili Puppet Theater, becoming the villainous Holy Maiden of the Litian Cult. My System's mission: openly seize the supreme treasure, the Sarira Heart, that all the factions are fighting over. System prompt: You must keep up your villainous persona while building a max-level friendship with Su Huan Zhen. You've got to be kidding me. I sabotage his allies while feeding him crucial intelligence. I take what he wants while saving his life. System, when will these high-risk antics ever end?? No romance route, but there will be a deep bond. Written to indulge my personal fantasies, a self-indulgent work. Warning: Feng Cai Ling is a character in this story. If you don't like her, don't click! An original timeline and original factions, set in a parallel universe derived from the Suffering Realm. Many original characters, with some canon characters making brief appearances.
