My Good-for-Nothing Sister Kidnapped Xingqiong Xiadie as a Summoned Beast

(Post-apocalypse + shameless power fantasy + Haidilao + dual female leads + daily life + yandere + baihe. A special warning before reading: please throw away that lump of white tofu inside your head first.) My name is Su Shan. The first time I summoned, I got a C-rank, and became the laughingstock of the whole school on the spot. But she had no idea that the universe's one and only Observer was sleeping inside her: her mom. The Observer stood beyond cause and effect, commanded space and time, and could neither die nor be destroyed. Only after losing control of her power did she seal her source inside her beloved daughter's pocket watch and fall asleep. From then on, Su Shan set out on a grueling, cross-dimensional quest to reclaim that power, accompanied by Xiadie, an SSS-rank goddess of the underworld. Scythe-wielding butterfly, death dragon knight: that was the combat aesthetic of the daughter of the River Styx, with maxed-out skills and overwhelming style. The Observer's last words, meanwhile, were simply: "Can't be bothered to wake up. Hurry it up." This whole novel is the daily tale of the strongest summoner and the laziest ancient god constantly screwing each other over. They cross countless dimensions in search of fragments of power, and along the way beat the various gods until they question their entire existence. Behind supreme power is a heart that just wants to slack off. The hardest-core, most irreverent path to godhood in history: pierce all illusions with the Eye of Observation, and reap the gods in twilight with the scythe of the River Styx.
