“The Fang family had two daughters. Their youngest daughter, Fang Yan, was known for her beauty. Rumor had it that she was indescribably beautiful. However, the eldest daughter of the Fang family, Fang Liu, had a low IQ since she was young and only started to speak when she was eight years old. Her parents regarded her as a burden while the outside world treated her as a laughing stock.

However, no one knew that Fang Liu was an ultimate prodigy whose intelligence merely developed late. Afterward, Fang Liu got pregnant for no reason. Four months into her pregnancy, her parents forced her to marry the richest man in South City, the Mo family. Rumors had it that her husband was an old man who had been paralyzed in bed since the age of seven. Unexpectedly, when Fang Liu married into the Mo family, she found out that not only was her husband not an old man, he was also extremely handsome.

He was the Young Master of the Mo family that everyone admired—Mo Yu! Moreover, Fang Liu’s child was not even Mo Yu’s, but Young Master Mo did not seem to mind? Mo Yu even declared in front of everyone, “”Although the child isn’t mine, the wife is mine!”” Everyone else, “”Young Master Mo is too honest!”” After Fang Liu got married, Young Master Mo doted on her so much that even she was moved. She had found a great stepfather for her child! A few months later, Fang Liu looked at her newborn’s face and it nearly felt like she was looking at a miniature version of Mo Yu. Fang Liu, “”Didn’t you claim that the child isn’t yours?”” Mo Yu shrugged. “”I was just spouting nonsense.”” It turned out that there was no such thing as the right person at the right time at the right place. It was all premeditated. “”It’s because I love you that I’ve tried everything I can; I endured all the criticism for my only wish is to have you as mine.

Every mage when they reach the age sixteen were told to attend the mage academy and Kevin, the abandoned human who had overheard the conversation of some students, got excited to attend this academy.

He asked from his guardian if he could attend the academy but unfortunately, he was denied, all because of him being an human and not an Elf. At that moment, he became angry and had locked himself up in his guardian’s workshop, that was a room full of all types of magical items.

But while in the room, Kevin had spotted a golden ring that instantly glowed as soon as it touched his bloody fingers. Surprisingly, he was given a system that granted him the opportunity to be an Elf. But what he discovered was that, he wasn’t just an elf but a fairy and also an human.

The overwhelming Burning Legion, Malfurion on the front line saw his death as his own.

Outside the barracks at the rear, Li De leisurely started his singing.

A spectacle composed of countless terracotta figurines rises from the ground!

“Building Wonders: Terracotta Warriors.

Spectacular effect: All combat units are upgraded by one level! ”

“This…is this the power of a demigod?”
