Since ancient times, good and evil have coexisted, and light and darkness come from the same source. However, the distinction between evil and righteousness lies in one thought. If one thought is righteous, the person will be righteous; if one thought becomes evil, the person will be evil. Every time there are evil spirits causing trouble in the world and there is turmoil, there must be someone who will bear the weight of the common people, hold the sword of righteousness, guard the heart of the world, and reincarnate again and again. If the way of swordsmanship is the right way, the heart of heaven will be the heart of man.
