The last time she saw the Great Sage, she had seen the deep wariness in his eyes.
She had realized that the Great Sage had once again seen through her disguise. It was impossible for her to kill Tang Sanzang under his watchful eye.
Originally, she had wanted to risk her life and give it a try, but after overhearing the conversation between Pigsy and Tang Sanzang, she changed her mind.
Though the two of them had kept their voices low enough, she possessed cultivation. Not even the slightest rustle of wind or grass could escape her ears, so how could she fail to hear their whispered conversation?
When she discovered the rift between Tang Sanzang and the Great Sage, she knew what she had to do.
She knew she could not kill Tang Sanzang while the Great Sage protected him.
Then she was willing to trade her life for the Great Sage and Tang Sanzang to turn completely against each other.
As long as a rift formed between them, and the Great Sage no longer protected Tang Sanzang on his journey to the Western Heavens, he would not become the lackey of the gods and Buddhas filling the heavens.
Thus, White Bone Spirit gave her life for this plan.
She was willing to disperse her thousand years of cultivation and shatter the body she had painstakingly condensed, all so Sun Wukong could awaken and understand that he was not Ascetic Sun, the one who protected Tang Sanzang on his journey to the Western Heavens, but the free and arrogant Great Sage Equal to Heaven who stood atop Flower Fruit Mountain!
Although she had not had the chance to say a single word to the Great Sage, she was content to die for him.
Great Sage, would you remember me?
