Jordan offered to let Rong Huangde control him with poison so as to dispel Rong Huangde's worries about him.
All for the sake of waking Victoria up as soon as possible. On one hand, he was doing this because he loved Victoria deeply and wanted her to wake up quickly. On the other hand, it was also for safety's sake.
If Jordan helped Rong Huangde explore the secrets of the Handley family's ancestors first, who knew what kind of danger he would encounter? He might never return. If Jordan died, who would save Victoria?
Jordan didn't think Rong Huangde would be so kind as to save a woman who was as good as a stranger to him.
In addition, Rong Huangde had explored the Handley family's secrets for so many years, but he had not discovered anything. Even if Jordan was a Deity, it would definitely take a long time.
Jordan didn't want Victoria to wait that long.
