This Holy Lord Isn't Very Proper

In ancient times, the Celestial Realm was in turmoil, with battle after battle raging across it.

A thousand years ago, the greatest Sage of Merit used his formidable power to suppress all sides, defeating everyone in the Celestial Realm until none dared call themselves supreme.

Thus the Celestial Realm was united, and the immortals of every faction submitted. From then on, peace reigned throughout the land.

After the war, the Sage was moved to transform himself into a mortal and undergo a tribulation in the human world.

Ten thousand years later...

“I, Su Daoyan, the Sage of Merit, have returned!”

But this world is far from as peaceful as he imagined. One powerful enemy after another appears. What will Su Daoyan do?
