The power of the soul is like water, clear and transparent, and can be bent and stretched, but it is changeable and invisible. Physical strength is like earth or a mountain, thick and orderly, and its entity is permanent, so it is not easy to change. A tangible thing.
Take a little essence from the invisible soul and plant it in the tangible body. If the presence and absence complement each other, you can get a soul source seed, which can cooperate with the physical attributes to activate the soul source. It can hurt people and save people. It is called soul magic. The stronger the power of the soul, the stronger the soul source seed it emits, and the easier it is to improve the acquired practice. The method of soul cultivation is called Taoism. Taoist means "learning method". It can absorb the soul energy that cannot be sensed by the physical body into the body, strengthen the soul source, gather rocks to form mountains, and melt rivers to form seas.
Each soul technique has its own advantages and disadvantages, but it depends on the overall strength of the user. The purer the soul source, and the more skilled the person is at controlling his own soul source, the more powerful the soul technique will naturally be. Soul technique is the way to use the soul source.
