【Revising the story. What a mess. I have to update it before I can make changes, and I've forgotten where I left off. Damn, time to go through it all again.】 The Great Yin Dynasty: Ji Zijing: “Are you Chinese?” No one answered. “Odd numbers change, even numbers stay the same; the sign depends on the quadrant...” Princess Xiao Lingyu: “I haven't saved the 800-word essay I wrote about my inheritance.” Ji Zijing: “Aw, damn, that's rough.” Fellow hometown... Tianxuan Sect “Shit, why do I keep running into a bunch of idiots?” Bai Qianyu muttered under her breath. The usually aloof senior sister beside her patted her shoulder. “Who are you?” Bai Qianyu: “Ji Zijing.” Senior sister: “Xiao Jin'er~ Fancy running into you again.” “Holy crap, Xiao Yun'er, your identity is insanely impressive again. Please look after me.” The Immortal Realm: Immortal Qingyu: “What a bunch of brain-dead idiots. All they do is bully me, then send me to the Demon Realm to rescue someone. What a shitty mission. Aaaah!!!!” Demon Lord: “Immortal Qingyu, are you having a breakdown here?” “Holy crap, what was that? You scared my heart right out of my chest. I need to call 120!” “Little one, there are no ambulances here, but we do have Rebirth Pills, immortal power, and demonic energy.” The Demon Lord's hand traced along Lin Qingyu's neck as he chuckled. “Xiao Yun'er, is that you?” Lin Qingyu asked in a timid whisper. “Damn, Xiao Jin'er, it really is you again.” Ji Zijing: “Xiao Yun'er, protect me!!!” Some of the tags were added automatically by Tomato based on the story.
