Doomsday's Otherworldly Heavenly Venerable

The last heir of a family of practitioners of Daoist arts, in an age when the vital energy of Heaven and Earth has run dry and Earth’s energy resources are depleted, Zhang Bufan and his siblings fight their way upstream amid ceaseless conflict. They slay demons and vanquish evil, battle the forces of various nations in the open and behind the scenes, and continually strengthen themselves and their team of brothers and sisters, ultimately attaining supreme status.
