Old Woman

To conquer a sanctuary and become an overlord in Eternal Chaotic World, Great Emperor Colored Glaze wasn't stupid.

Plus, she was pretty well-informed.

The war that had happened in Lineage of Star, she knew about it and she had naturally heard of the mysterious expert from ancient times, Emperor Thirteen.

He was a super expert and he was definitely related to Jian Wushuang. He absolutely wouldn't allow Jian Wushuang to die.

Back then, Abysmal Saint Master had wanted to kill Jian Wushuang. In the end, Emperor Thirteen had popped up from nowhere. With one stroke, he had almost killed Abysmal Saint Master. His terrifying power was only stronger, not weaker than, Emperor Bai's

She wasn't even as strong as Abysmal Saint Master. Hence, she didn't have the courage to kill Jian Wushuang.

As for what she had promised Sir God Xue Dao, she merely wanted Sir God Xue Dao wanted to lead her to Green Fire World. She had never thought of killing Jian Wushuang.
