Wen Shi was a fox spirit. After he died, the System bound him and sent him into a horror game corrupted by a virus.
The System said that if he purified the legendary ultimate villain with an antisocial personality and restored the game to normal, he could be reborn.
Wen Shi obediently nodded. He quickly found the supervillain rumored to have an antisocial personality and, as the System screamed, sincerely said:
"Hey! You're antisocial, right? Then let's team up and wipe out humanity together!"
The villain: "...?"
The System: "That's not how this works!!!"
The villain sneered. "Sure. Why don't you kill one first to prove you're sincere?"
The very next second, the villain watched Wen Shi casually grab an NPC and rip them in half.
Wen Shi's eyes sparkled as he asked, "Can we work together now?"
The villain: "?"
Shen Xuyan was originally an NPC in a horror game. But after the game was unexpectedly invaded by a virus, many NPCs were infected and turned into monsters. He became the strongest monster of them all.
He was sick of this life. He hated humans, monsters, and everything in the world.
He curled up in a dark room, letting the darkness swallow him, sinking into despair and decay, day after day...
"Bang!"
The door was kicked off its hinges. Wen Shi shone a glaring flashlight right in his face and shouted indignantly, "What's with you, little Shen? Hiding away and slacking off again? Hurry up and come help me wipe out those awful humans!"
"..."
Looking at the spirited young man standing in the doorway, Shen Xuyan was silent for a long time. Then he left the room and smiled. "All right... boss."
Bonus scene
Shen Xuyan finally worked up the courage to find Wen Shi and say, "I'm not human."
Wen Shi barely reacted. "Oh."
Shen Xuyan: "?? I said I'm not human!"
Wen Shi swung his fox tail and smacked Shen Xuyan with it. "What's so special about not being human? Why are you so proud? I'm not human either, and I'm not bragging about it!"
1. Both are each other's first love, and both are each other's first partner, first kiss, and first handhold. No stand-ins, no first loves in the background, no misunderstandings, no pretending to be actors. They are each other's one and only.
2. The NPCs killed by the protagonist are NPCs who turned evil after being infected by the virus. He doesn't kill innocents indiscriminately. Neither the protagonist nor the love interest has done anything contrary to core socialist values, so please go easy on us.
3. More to be added if I think of anything.
