I'm Really Not the Dao Ancestor

Chen Fan transmigrates into a cultivation world and is trapped in a gorge, unable to leave. His aptitude is also too poor to cultivate, so he has no choice but to follow the System's prompts and live a quiet life. Little does he know... The old man who wandered into the gorge by mistake is the progenitor of the human race. The wild fox he healed is none other than the Dao Patriarch who would later teach the world. The middle-aged man who learned blacksmithing from him would go on to become the founder of spiritual treasures among the human race. The boy he taught to draw would become the founder of formations in later generations. When he finally looks back, the entire world, whether human or demon, calls him by one title: Dao Ancestor!
