The state of full body requires that one have total control of their body. This is the only way that loss of power during movement will be achieved.
Swordsmen like him are required to achieve the state of full body in order to become true swordsmen, not just mere men swinging swords.
In fact, the state of full body is not that special. The main difference is that people who have achieved this state will be equal to those who use spells.
The power of the body will become completely reproducible with the sword. But the power that they can produce is at most the same level as their cultivation in either body forging or energy forging.
The special advantage of the path of the sword only begins to show itself in the second state of the oneness with the sword. This second state is called full energy.
The state of full energy is when the power of internal energy or life energy and the body is combined. In that state, the power that can be produced will be doubled.
