Lacking Trash Talk

The spectating Martial Artists were so engrossed in the unfolding battle down below to the point that they had forgotten about their original objective, which was making sure that the other side didn't interfere with the battle.

Instead of focusing on their enemies, more and more Sages and Masters began dedicating most of their attention to watching the two strongest Masters duke it out with each other.

They marveled at the endless versatility that Tokugawa Ieyasu displayed and the incredible adaptability that Rui demonstrated in response  to everything that the former had thrown at him. One after another, Ieyasu unleashed Martial Art after Martial Art and, one after another, Rui adaptive evolved.

He adaptively evolved not only to all of Ieyasu's copied Martial Art, but also the assimilated Martial Art hybridized with every Martial Art that Ieyasu had ever copied. Each time Ieyasu pulled out a new trump card, Rui managed to overcome it narrowly.
