I Want Eternal Life, and I Come from the Apocalypse

My name is Fang Yuan. I am a transmigrator from the apocalypse on Blue Star, recently transferred back to Mingyue Sect from Sanhe Market. I brought a virus with me from my previous life. I have less than ten years to live, so my first goal is to get the life-extending pill in the sect master's cave abode. I will take over the sect master's cave abode. My name is Pei Muxue. I am the holy maiden of the Demonic Sect, sent by my master to secretly investigate Mingyue Sect. Mingyue Sect is hiding a huge secret! The disciples here never fight among themselves. They are either cultivating, making talismans, refining pills, sparring, or going out to hunt demonic beasts... The elders have no factions either. They are easygoing, eager to teach, and impartial. Even their own sons are punished severely when they break the rules. It's suspicious. Extremely suspicious. Especially that outer sect disciple named Fang Yuan. Every night, he goes in and out of the sect master's cave abode without fail, as if it were his own home. “Huh? Why is every disciple I pass staring at me?” “Their eyes are turning red...” “Uh-oh, I've been found out. Run!”
