The former Demon Venerable's only son, abandoned in the human world, is an aimless lazybones who lives off others and waits to die. One day, curiosity got the better of him, and then beauty beguiled him into "stealing" his boss's new bride. He even "occupied" the bridal chamber, only to discover that the bride wasn't a beautiful young woman, but a handsome immortal lord.
Mm... Things happened so fast, like a tornado. This useless, good-for-nothing son of the former Demon Venerable decided he needed to think carefully.
But his husband really was beautiful, a peerless beauty unlike any other in the three realms or nine provinces. So... he wasn't entirely opposed to becoming a bit of a sleeve-cutter.
But he never expected that just when he finally made up his mind to love a man, his husband would leave him, take up a sword, and head off to the battlefield!
This was going to be the death of him.
What was the point of fighting all the time?
It was bloody and not at all elegant.
He found it utterly distasteful, but his husband was out there fighting!
The good-for-nothing son of the former Demon Venerable felt miserable. He had no choice. For his husband, he'd give it everything he'd got!
In the end, the good-for-nothing finally won his beauty's heart and became the new Demon Venerable.
Mm... you could say he inherited the family business.
But after that...
"Immortal Lord! Please persuade the Venerable! The main hall is already buried under memorials from every faction! The ministers can't even find a place to stand when they come to submit their reports!"
"Immortal Lord! If the Venerable doesn't come out and take charge, our demon realm will fall into chaos again! Please, we're begging you!"
The immortal lord, who loved peace and had a terrible temper when woken up, kicked the lazybones sprawled across him out of bed, tossed him out of the hall, and firmly shut the door.
"Don't come back until you've finished dealing with everything."
