The Older Brother of My Student is My Secret Crush - Chapter 23: Qiao Rui Injured.

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.

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.
