MTL - Black Dragon Kingdom - Chapter 518 Fair to the end

A useless prince, yet brimming with kindness and compassion—his smile as warm as sunlight, illuminating this darkened era.But that was merely a mask, hiding the poisonous and mad nature beneath.A monster lurking behind a gentle shell.A system that feeds on stolen Heroines.He will outplay destiny—and rise as the world’s ultimate villain.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

PS. Cover not mine, I just found it on google.

After waking up from a car accident, not only was I alive, I had also gained a new ability. If I stare at someone or a photo for three seconds, I’m able to see whom and when they shall marry… The 18th tier small-time actor Shen Chuchu knew that with this skill, her mother would never have to worry that she will starve to death again. She would put down her roots on Weibo first, then open a matchmaking store on Taobao.* “Your husband is a close friend and you will be married in March next year. You will have a happy marriage.” “Your husband will appear at your company’s dessert store soon, so remember to keep a close watch every day.” …… *Note: Weibo is a popular social media app in China with functions similar to Twitter. Taobao is basically the Chinese eBay/Amazon. A certain amateur celebrity is already married? A certain director’s wife is going to have an accident soon? One day, someone came to her for matchmaking. “Sorry, lady. Fortune-telling requires fate, and it seems like we don’t have that between us.” “Isn’t this just about money? As long as you can figure out my son’s marriage, I can pay you tenfold. No matter how much!” F***ing hell, it wasn’t that she wouldn’t predict the match. The arrogant CEO’s future spouse was actually her.

When he did not know her true identity, he treated her very badly, he disliked her too much, she was not elegant enough, she was in the way...Only later did he realize that the woman was his legal wife! He repented, tried to recover her feelings, but she was determined to divorce him.
