Wear Yourself as a Microorganism, Pretend to Be a System, and Become an Immortal

Liu Dong didn't expect that he would travel through time and become E. Coli. The day the host was annulled. "Ding! Congratulations on unlocking the Immortal Cultivation System and completing the task: swallowing three Polygonatum japonica plants will reward you with spiritual enlightenment." The host was ecstatic: "Have I awakened the system?" Liu Dong in the host's belly sneered: No, I'm hungry. Just one year later, the host's cultivation soared, and the entire sect was shocked. No one knows, A fungus kingdom has been built in the host Dantian. No one knew that in just a few years, The genius of the sect, the saint of the back mountain, and the incarnation of the two paths of good and evil, all have clones of this E. Coli in their bodies. And this E. Coli keeps evolving by absorbing the nutrients from these donors. Finally, he swallowed the world and became the Taoist ancestor.
