Skeleton Knight, in Another World - Chapter 13Volume 4 -

Reborn into the world of Yugioh, it's natural if my goal is to become the best duelist!

Cho Ryu Hyang was good at math from a young age. When he enrolled into the The Theoretical Maths and Martial Arts School, the teacher, Jo Gi Chun, recognized Cho Ryu Hyang’s talent immediately and took him in.

As the Gods descended onto Earth to bless their children to save them from the threat of extinction, supernatural beings were born with the help of the System.

However, not everyone was blessed.

Zayn was a “Normie”, but he was quite happy about that!

Who the hell needs the Blessing of a God or a spoon-feeding system?

I don't!

As long as I had the Grimoire of the Ancient, some fragmented memories of my past, and my Army of Spirits, not even Gods would dare to look me in the eyes!

The ninth son of the Tianhan Immortal Emperor of the fairy realm, Qin Yun had the rare gift of the Chaos Immortal physique and even achieved the cultivation level of Real Immortal at ten years old. He was so skilled that his father was considering making him the successor to the throne.

But his idyllic life was shattered at the hands of a massive conspiracy, and the Immortal Emperor, his own father, not only exiled his mother to endless torture in an unfathomable abyss, but he also sealed away Qin Yun’s intelligence and memories away and banished him to the mortal world.

Stuck on Earth as a helpless child, he is taken in by a beautiful woman in a small town who adopts him as her younger brother. Things are fine for a while, but when a bully attempts to extort his newfound sister for sex, and no one is willing to stand up to him because of his powerful friends, can Qin Yun tap into his old skills to protect her?
