Save My Sister

After the Abyssal Rift descended, humanity entered the Era of Beast Taming—ordinary people could only form contracts with spirit beasts, but office drone Wu You unexpectedly awakened the 'Eerie God Sovereign System,' becoming the sole human capable of contracting terrifying, unnatural entities. To save his critically ill sister Wu Mian, he successively contracts powerful eerie beings: Nie Xiaoqian, the Drought Demon, the White Snake Spirit, and the Painted-Skin Ghost.
