"Because I suspect Xu Xueman might hold the final piece of information that could reveal the secrets of the Abnormal Skill, if it really exists, the poison in your wife's body might be removed!"
After the battle with Lei Shi, upon learning that the Abnormal Skill documents had been burned, Qiao Ran had always felt regretful and blamed himself for not protecting the precious information and failing to fulfill his promise to Tang Hui to detoxify his wife.
Not until Lei Shan was poisoned and nearly beyond rescue did Qiao Ran finally think of the crazed Xu Xueman.
Qiao Ran had never doubted that Xu Xueman had gone mad.
For a mother to lose three children was the deepest and most painful sorrow in the world.
He had always believed that Xu Xueman truly lost her sanity.
After Lei Shan was poisoned, he re-examined Xu Xueman, whom he had overlooked, reckoning that as a new generation Abnormal Skill Inheritor, Song Wanrou certainly would have made backups of important matters.
