The battle was still ongoing. Although the Bone King had been cracked by "Big Horn," it wasn't truly damaged; instead, this also had to do with its attribute of versatility. To be frank, it was just like plasticine, as the Bone King had the ability to mold itself into the shape of any weapon Loopy Toad wanted with a thought.
If you poked a hole in plasticine, you just needed to mold it back into shape.
Therefore, when Loopy Toad saw the fresh cracks in the Bone King slowly restore itself, it felt that this attribute was simply heaven-defying and equivalent to built-in self-regeneration! — Little Master Ling never has to worry that my magic weapon will be destroyed!
