Double Realm: Holy Emperor of Life and Soul

Hidden behind the prosperity is a crisis of despair. Humanity and the created civilization are facing the crisis of extinction. As the last hope of mankind, Fang Jie, by chance, traveled to the corresponding parallel world while performing a mission to travel through the vortex of time and space. In the new world, there is a completely different power system - the fusion of life and soul. Use soul seeds to build structures to fuse life souls. The structure that the predecessor could not build was because Fang Jie was the only one to use the high-order equation functions he solved to build the structure, integrating the unprecedented Five Sacred Souls. From then on, he embarked on the path of the Soul Saint Emperor.
