The emperor didn't care about the empress dowager's life or death. What he cared about was why she had these symptoms.

He was not in a hurry to go over, but instead asked the guard to explain the whole process in detail.

He Yanting noticed that Jiang Zhiyu's frown was getting deeper and deeper because of the guard's words.

When Jiang Zhiyu heard the guards say that the Queen Mother kept shouting for calming incense before she had an attack, her pupils shrank slightly and she understood everything in an instant.

[The Heavenly Dao is really hungry and can eat anything! ]

[The tranquilizing incense Song Shiwei gave her must have contained something addictive. Judging by the potency, it must have been quite a bit.]

Addictive substance? The first thing the emperor thought of was Wushisan.

Wu Shi San was initially used on a large scale on soldiers seriously injured on the battlefield.

This thing can make them forget the pain in their body temporarily so that they can receive treatment from doctors.

For a long time, Wu Shi San was an indispensable medicine in the army.

Until a great battle with Mobei, there was very little Wu Shi San left and it was out of supply for a while. It was fine at first, but after a few days, the soldiers became crazy and looked like evil spirits.

Their craving for Wu Shi San made them desperately search for it, either hurting themselves or biting others.

There was great chaos in the army, and the people from Mobei took advantage of the situation and invaded.

It was also in that battle that He Yanting was seriously injured and almost lost his life.

Since then, the emperor has listed Wu Shi San as a banned substance.

So, how did Song Shiwei get this thing?

The emperor immediately thought of Xiao Yanli.

"Send someone to Song Shiwei Palace to investigate. Check it thoroughly for me. Don't let a single trace go unpunished!"

The guards took orders and withdrew, and the emperor walked towards the Cining Palace.

He Yanting and Jiang Zhiyu followed closely behind.

When they arrived at the Cining Palace, the empress dowager had already fainted on the ground. The imperial physician was beside her, treating her wounds.

The emperor glanced at the empress dowager and asked, "What's the matter?"

"Your Majesty," the imperial physician withdrew his hands and bowed, "The Empress Dowager has not been poisoned. I believe she may have been poisoned."

The emperor expressed doubts about his statement and looked at Jiang Zhiyu.

Jiang Zhiyu's expression was unusually serious. She half-knelt beside the empress dowager and scanned her body with her special powers.

[As expected, I inhaled too much addictive drugs.]

If she continues to inhale this level for a few more days, she will die.

Jiang Zhiyu's tone was cold: "It's not poison, it's addictive drugs, and the dosage is quite high."

The emperor's face looked grim, as if covered with a layer of frost. His brows were furrowed, and he looked solemn, with an awe-inspiring severity.

The imperial physician lowered his head, not daring to look at the emperor's expression again.

Meanwhile, the Jinyiwei sent by the emperor to search Song Shiwei's palace also came running over, panting and reporting: "Your Majesty, we have almost turned the palace upside down, but we have found nothing."

To prevent the emperor from scolding them, they also brought Song Shiwei with them.

Song Shiwei was pushed in confused, and his face changed when he saw Jiang Zhiyu.

I don’t know when it started, but every time they meet, I always look so embarrassed.

But it is obvious that when they were young, Jiang Zhiyu was the one who was in a miserable state!

The emperor looked at Song Shiwei, who was being held down by the Jinyiwei, with his deep eyes, and said in a voice as cold as ice: "How did you get this thing?"

Song Shiwei's face was pale and his expression was dazed, his frightened eyes moving around helplessly.

She really didn't understand what the emperor was talking about.

She asked cautiously, but saw that the emperor's face suddenly became uglier. He raised his hand, a clean and neat movement that could not be resisted or questioned.

Song Shi was slightly stunned.

Then, the emperor said in a cold voice: "Imprison her to the Heavenly Prison. I don't care what kind of torture you use. As long as you can pry the source of this thing out of her mouth, I will reward her with ten thousand taels of gold."

Song Shiwei: “!!!”

The rest of the people: “!!!”

Song Shiwei was completely confused.

Since the last time the emperor came, I sold the empress dowager's secret to the emperor according to what was written on the note, and I thought everything was fine and the emperor would let me go back soon.

She relaxed and waited.

But what she waited for was only the Jinyiwei rushing around recklessly and the emperor who wanted to put her in the sky prison without saying a word.

She felt panicked in an instant, as if a hand was tightly grasping her heart. A tingling sensation suddenly spread throughout her body and her hands began to tremble.

"Your Majesty," Song Shiwei said in a dry voice, "I don't know what Your Majesty wants to ask!"

Her eyes were filled with tears and she looked at the emperor pleadingly.

"You don't know?" The emperor didn't even look at her. "Everyone in Tianqi knows that Wushisan is a forbidden substance. You mixed it into the tranquilizing incense and let the empress dowager inhale it every day, and you still say you don't know?!"

Five Stone Powder?!

Song Shiwei's eyes widened instantly, and besides being surprised, she only felt a sense of injustice: "Your Majesty, I know for sure that this servant of yours does not possess any Five Stones Powder!"

Because of the Five Stones Powder, the emperor killed almost half of the people in the city. From then on, the emperor would rather kill someone innocently than let anyone who had anything to do with the Five Stones Powder go.

This is enough to show how much he hates Wu Shi San.

Song Shiwei fell to the ground, his body shaking uncontrollably because of fear.

The person who designed the emperor to believe that she was involved with the Five-Stone Powder was definitely going to kill her!

As Song Shiwei was thinking this, he suddenly raised his eyes and stared at Jiang Zhiyu.

It must be her! No one else but her!

"Your Majesty, I was framed. I absolutely do not possess any Five Stones Powder!"

Apart from repeating over and over again that he didn't have it, Song Shiwei couldn't think of any other rebuttal.

Her words were not convincing at all. The emperor's expression was cold: "If that's not the case, why is the Queen Mother in such a state, still muttering about your tranquilizing incense?!"

Song Shiwei: "..."

Her hands were clenched tightly together, her fingernails digging deep into her palms, as if she was trying to suppress the impulse in her heart.

The emperor was already impatient, and seeing that Song Shiwei was speechless, he sneered and moved his fingers, signaling the Jinyiwei to take the man away.

"Wait, wait... don't touch me!" Song Shiwei struggled to break free from the Jinyiwei, crawled forward a few times, and grabbed the corner of the emperor's clothes: "Your Majesty, it's vanilla, just vanilla!"

Herba Citriodora?

The emperor's eyes were cold. This kind of thing could be found in large quantities in the palace, even in the homes of ordinary people.

He had never heard of anyone becoming addicted to vanilla.

Song Shiwei also knew that this statement was untenable, and said in a dry voice: "Ordinary spices cannot achieve the addictive effect. It needs to be mixed with my special fragrance, which is called cold brew, to achieve this effect."

The emperor narrowed his eyes slightly, took a deep breath, and ordered, "Bring some of the empress dowager's calming incense, and find a few perfumers to come along."

Song Shiwei was still holding the corner of the emperor's clothes, and the emperor frowned and kicked her away.
