As Yoze continued to improve his connection with the white tiger he could feel that once he reached level three of the Beast Human body cultivation method he could now feel that there was a large improvement. Copying what he did with the giant serpent, Yoze continued to make the white tiger's body continue to produce inner vigor while its internal inner vigor went into chaos.
In the chaos, large bundles of sharp inner vigor untangled and were forced into the white tiger's bones. More and more inner vigor was absorbed into the white tiger's bones, making the white tiger's teeth and claws noticeably sharper.
From what he predicted the white tiger's claws and teeth at the base form now were as sharp and deadly as when it inputted inner vigor into them. Before, the white tiger needed to use every last drop of its inner vigor to cut through steel, but now it no longer needs inner vigor to cut steel.
