The Returned Son-in-law Now Became King

Six months after vanishing on the second day of his wedding, he finally came back!
Meanwhile, his wife's family had already gone bankrupt! To her, he had abandoned her at her most desperate and challenging time of need!
They didn't know that, at that time, Chu Yun experienced a world that was darker and worse than one could imagine. Not worrying about tomorrow's dinner was a common occurrence!
The in-laws cursed him for being useless. They resorted to every form of manipulation they could think of to break up the marriage. However, he no longer desired the divorce once he learned of his wife's struggles!
With a flash of coldness in his eyes, he gave off a menacing vibe! 
Trying to scheme against his woman!? They have no idea who they are on the path to offended!
He could hide his ruthless side for his wife, but to those who provoke his dignity, he would become a "Devil King."!
