Hidden for a Thousand Years: From Demon of Original Sin to Holy Kingdom Leader

Su Mo, a citizen of the Celestial Empire, woke up one day after transmigrating to a world of swords and magic, where he had become an Abyssal demon.

From the start, the Demon God King sent him to the outside world as a spy, and he also awakened a Faith System.

And so Su Mo spent a full thousand years among humans, even founding a country of his own.

Then one day,

The Demon God King's apostles found Su Mo and ordered him to work from within, helping them break the seal.

What they didn't expect was that Su Mo immediately cast a Grand Light spell.

"Sorry, but I'm the leader of the Holy Kingdom's church now."
