- Description from Novelupdates

Right after getting the first-class chef’s certificate and before that certificate had been in her hands long enough to warm up, she woke up. Not only did she age ten years, she also gained two children…

—

At this time, her new daughter, who had lost two of her front baby teeth and spoke with a lisp, pointed at the TV screen and called out, “Dad!”

On the screen, the Film Emperor Meng Yan was extremely handsome and charming. Towards the camera, his gaze was overflowing with gentle and tender feelings. He raised up the hand that was holding hands with captivatingly beautiful bride. She was wearing a diamond-beaded wedding dress. At the bottom of the TV screen, the headline news was displayed in large font – Meng Yan and the rising starlet’s wedding of the century.

T/N: The second part of the summary is misleading. This isn’t a novel where the transmigrated main character clings onto the film emperor’s thigh.

"Magic is believing in yourself, if you can do that, you can make anything happen."

Ikaris, a genius student admired, exploited, and hated all his life for his brilliance, suddenly finds himself transmigrated into The Forsaken Lands, a fantasy world of myriad species born with the ability to use magic with imagination as their only limit.

Alas, this gift carries a curse. The more you use it, the closer you are to death.

Follow him on his journey from an ordinary human to a shining existence that will overturn the order established since the dawn of time. From an innocent soul to a merciless demon. From a human to something else.
