Li Jiangqiu was almost swallowed and torn apart by magic power when he was born. He was sealed with magic power by the patriarch and survived. Later, he went to England to study magic with the patriarch's son, Crowley Reed.
Unlike his senior brother Cullo, who is full of magic genius, Li Jiangqiu often encounters various accidents when using magic due to being sealed and having too strong magic power to control. Because his senior brother Kuro had no major accidents and could more or less control his magic, he felt free to stay and learn magic by himself when he returned to China to visit his mother. I didn't want to inject too much magic power when reciting the spell, and suddenly he was transported to Japan's Warring States Period, and fell into the underworld. It would only be worse!
