The Souls of the Three Realms

Hold the contract that holds the soul, and capture all evil souls. The soul between heaven and earth inherently contains two natures of yin and yang: the yang soul controls the five elements of spiritual energy and is the foundation of spiritual practice; the yin soul controls the power of the soul and is the core of soul training. However, the boy was born without a Yang soul, and when he was eight years old, he was told that he would not be able to embark on the path of spiritual practice in this life. But is this ending really destiny already written, or is it a chess game secretly set by some god?
