Prison Cultivation Sect

550,000 Years ago. Monsters are sweeping across the Xianyuan Continent, and the human race is in danger. At the last moment, the first sect, Liuyun Sect, activated the sect-protecting formation. The human race was able to retain the last trace of its blood. However, while the sect-protecting formation isolates the monsters, it also isolates the spiritual energy. 550,000 Years have passed, and the spiritual energy in the sect-protecting formation has long been exhausted. The monks cannot practice by absorbing spiritual energy, and can only rely on monster meat, elixirs and other external substances to practice. With the help of the black dantian, Lin Feng's cultivation level improved rapidly. Soon, Lin Feng entered the inner gate of Liuyun Sect and the inner world created by the great master of Liuyun Sect. At this time, he unexpectedly learned the secret of his life experience that made him despair. What's even more terrifying is that he gradually discovers that there seem to be too many coincidences in this world. After he breaks through to Wonderland, he plans to exact revenge on everyone involved.
