Why Is Senior Brother Like This?

[Original title: The Senior Brother Whose Core I Dug Out Has Been Reborn] The apocalypse of the cultivation world has arrived. That night, the spiritual energy in the cultivation world suddenly ran dry. The way to increase one's cultivation was to dig out other people's inner cores and use them for oneself. You either got killed, or killed someone else. For a time, slaughter spread throughout the entire cultivation world. The male protagonist, Lu Zhuoyu, is an utter bleeding heart. Amid this apocalypse, he refused to cut open people's stomachs and dig out their cores to strengthen himself. Instead, he devoted himself to uniting the cultivators, all with their own hidden agendas, to open the Gate of Heaven, release spiritual energy, and save the cultivation world. In the end, his beloved junior sister brutally dug out his inner core, and he fell to his death at the Ghost Cliff. After being reborn, the first person Lu Zhuoyu sought out was his beloved junior sister. An eye for an eye. As luck would have it, Su Ningying transmigrated into a book as that very junior sister. Su Ningying: QAQ. A compassionate, living Bodhisattva with the face of Guanyin, but truly a vengeful Yama × a weak, pitiful, helpless little book-transmigrating fairy An unconventional apocalypse story, with plenty of original worldbuilding, a goofy tone, and a touch of ensemble cast.
