Get the Ultimate Battle Instrument at the Beginning of Oku Gaiden

There is a legend that there are two pairs of rings, one is black and the other is white. It's called the Yin Yang Ring. Yin ring can kill people, Yang ring can save people. When the yin and yang rings merge into one, you will gain extremely powerful and magical ultimate power. This book is tentatively divided into three chapters, the Yin and Yang chapter, the Yang and Chakras chapter and the final chapter of Yin and Yang. This time, I write about the Yin Ring. A good-for-nothing young man who lives in the Kongming Continent and has a blood feud accidentally activates the Yin Ring and receives guidance from the spirit of the Yin Ring. From now on, I want no one in this continent to dare to bully me - Dongfang Yu.
