The letter that Lin Yuelan received informed her that Jiang Zhennan was suspected of poisoning the Emperor and plotting a rebellion. He had been imprisoned in the imperial prison.
Lin Yuelan looked at the message and laughed instead.
Jiang Zhennan poisoned the emperor?!
The old emperor was poisoned?!
The old Emperor was controlled by Jiang Zhennan?!
What a joke!
The three Detoxification Pills she gave the old Emperor could detoxify all poisons. Even if the old Emperor were poisoned, as long as he was still breathing, he would be able to detoxify the poison by eating the Detoxification Pills. In a short while, he would be back to life.
Therefore, there was no such thing as the old Emperor being poisoned and controlled by Jiang Zhennan.
Besides, why would Jiang Zhennan suddenly poison the old Emperor for no reason and control him? This was treason.
