Noble Lady Hui breathed her last.
She did not betray the mastermind behind the scenes, and in the end, she even stopped implicating Noble Consort Qi, allowing herself to be beaten to death by the guards under the furious Emperor's orders.
No sooner had Noble Lady Hui ceased breathing than her body began emitting a thick, foul stench.
This was a side effect of the Western Regions Enchanted Incense. Although it produced a fragrant aroma while the person was alive, after death, the incense caused the body to rapidly decompose, emitting a foul odor from the internal organs that would continue even after the body turned into a white skeleton.
This was what was meant by "an eternal stench."
But as they say, "Death is like a snuffed-out lamp." Perhaps, in a sense, death was a release for Noble Lady Hui.
Yet, the Emperor felt no relief from her death. Not only had he lost his last offspring, but his body had also suffered greatly.
