Facing Chu Lan's questioning, Wei Ruo wasn't flustered and slowly began explaining, "I can prove that the late Daxing Emperor's death was unusual without damaging his body. The poison that the Daxing Emperor was exposed to was the perfume of Drunken Love. This poison is a mixture of two non-toxic substances. One is Wind Ring Fragrance, which you mixed in with the ambergris tribute from Fujian, and the other is Extinct Frost Shadow, which you've mixed into the tribute tea leaves."
"As both of them are non-toxic individually, they were not discovered by the testers for the Emperor. But if we investigate a little, we can ascertain whether King Jing intervened in transporting these two items to the Daxing Emperor."
