Faced with such a crisis, the Magic Tool Incarnation was not coerced into submission at all. If he didn't obey Lin Yun, the King of Nightmares' soul would likely swallow both of them. Then, Lin Yun would be completely gone, and the King of Nightmares would occupy his body. The Book of Death would become part of his body too.
With the natural-born extraordinary life and the natural-born Extraordinary Magic Tool, it might really be possible for the guy to reclaim its former glory.
The Magic Tool Incarnation would rather die than unwillingly yield. Lin Yun found him quite admirable. In the real history, the Magic Tool Incarnation had never surrendered ever since Bane acquired the Book of Death.
When Bane reached the strongest period of his life, he was capable of destroying the Book of Death, but the Magic Tool Incarnation still didn't yield. Bane didn't destroy it because of that.
