In this blood gate mission, Ning Qiushui, his companions Bai Xiaoxiao, Liang Yan and others entered the extremely difficult seventh blood gate to face an unprecedented test of survival. This time, they not only have to save their own lives, but they also have to protect four target people within five days from being killed by the boss in the Blood Gate. Every time a target dies, Mei will awaken an ability. The stronger Mei's ability, the lower the chance of survival of the trickster.
