Lann heard Iwami Yixin's request, so he no longer pursued the perfect timing and angle to block the incoming blades.
Instead, he simply held his sword horizontally to block the attack route.
The clash of blades lost their crispness due to the lack of technique, and sparks no longer exploded in a circle.
If Lann had just encountered the Iwami Style when he first arrived, he would have likely lost his entire posture after hard-blocking seven or eight blades by now.
But now, though his posture had undergone some discordant deformation, he still maintained it.
Posture is the way warriors efficiently mobilize their muscles to work in conjunction. Whether defending or attacking, a stable posture is essential.
Iwami Style: Flowing Water—known by all Iwami people, flowing water is strong. Even when blocking attacks, one should not meet force with force but seek to overcome rigidity with softness.
