Long ago a war between both light and dark had risen, and the land, people, and kingdoms had gone into war over the yin and yang prowesses the war caused many to die at the hands of the yin and yang. After the dreadful war, both prowesses had vanished along with the original users, people began to go mad over them since both gave an individual an immense amount of power, spiritual energy, life energy, and knowledge. It had gotten to the point of non-stop searching for hundreds of years. Much later a boy by the name of Goshi Tomar was randomly chosen to yield the yin prowess as the yang prowess unravels.
It's cool to find a tree that holds a different world out there. Though both worlds the MC lives in are all waiting for war. Too much conflict, isn't it? Writing is good but needs editing. Update is accordingly done. Pace is relative. MCs are brothers, right? But I haven't read yet about Goshi's Yin wielder brother yet. He was mentioned in the synopsis. World setting elaborately described.
