Perfect World: Traveling Through Time to Become the Footprint Emperor, Kidnapping and Selling Fairy Materials

In a perfect world, He Yan actually traveled through time and became the Footprint Emperor before the Emperor's fall. In this era when the three heavenly emperors have not yet risen, in this era where strong men all bow down to worship strange people. I, He Yan! Bringing the only remaining glimmer of hope to the heavens! Unlocking the fusion system of all heavens and ten thousand ways, I must fight through the weirdness in this life... But the dark turmoil is not far away, and He Yan doesn't seem to have much time to integrate the heavens and the myriad ways... Eh! I have a plan. Can I, He Yan, find some immortals to serve as my disciples and help me cultivate the Tao? !
