The Emperor listened to Du Zheng's words and had to recall Song Xian's actions again.
Du Zheng said, "If Song Jiedu intended to do this, it's not impossible that he might be trying to evade responsibility after the incident. But... when thinking it over carefully, I'm still not sure. After all, Song Jiedu asked the Emperor to order a thorough investigation of those transporting Xiao Xingzong. If he tampered here, wouldn't he also risk being found out?"
A person scheming behind the scenes always has some concerns.
The Emperor looked at Du Zheng, "Perhaps someone else is plotting behind the scenes."
Du Zheng responded, "The poison used before shouldn't have gone wrong in theory. Whether the task was botched or done intentionally will only be known after the investigation."
"Take people with you and investigate," the Emperor said to Du Zheng, "You must ask about every detail clearly."
Du Zheng replied, "Such a situation has arisen, yet the Heavenly Family still trusts me."
