The Word that Sealed The Unknown 

Gradually, the Gravekeeper began to display signs of decline. At his level, once he began to weaken, his inevitable defeat would not be far away. Nanan and the others could not help but feel a little anxious. If even the Gravekeeper could not stop the Evil Thought, what hope did they have left?

"Sister Willow, can you help the Gravekeeper?" pleaded Dragin. 

The willow branches swayed in the wind as if shaking their heads. If the Gravekeeper had not rescued them just now, the Evil Thought's ultimate spell would have decimated everyone, including the willow branches. 

"Hahaha, you and I have been fighting for countless years, and I finally won! I told you a long time ago that it's only a matter of time before the arrival of a new era, and that I'd eventually reappear in the world!" gloated the Evil Thought. Then, he threw his head back in laughter while his aura became more and more powerful.
