When the Sun and Moon Demon Sect Is Established, the Emperor Is Only Qualified to Visit?

[Establish power + develop slowly + invincibility + cool writing + original characters + no heroine] Official introduction: By chance, he traveled through Chu Xuan and became the third prince of the dynasty who was on the run. He activated the Great Demon God System and established the Supreme Sun and Moon Demon Sect. Since then, he has been invincible all the way, killing gods when gods block him, and Buddha when he blocks Buddha! A few years later, the name of the Sun Moon Demon Sect spread throughout the world and became famous throughout the world. A certain ancient emperor was resurrected and looked at the majestic mountain gate and couldn't help but said: "Only such a sect is worthy of this emperor." One disciple complained: "Old man, what are you doing standing here? Don't you know that the gatekeepers here are all great emperors?" "There's still a shortage of people chopping firewood next to us. Do you want to go?" (Note: Because it is about establishing a force, the protagonist will allocate resources to his subordinates. If you mind, please do not enter.) (The author is a newbie writing a book. Please be merciful if the writing is not good. Feel free to criticize. I just want a few more stars.)
