Zhou Ning did not interfere with the investigation. She had too many things to do every day. Not only did she have to take care of everything in the palace, but she also had to keep an eye on her two sons.

Especially Li Laoer, he was like a demon king, giving her endless headaches.

"Hurry up and go back to bed. I'll wait for you Aye to come back later. I will definitely make you look good!"

Zhou Ning stared, Li Laoer lowered his head and played with the nine-ring chain, and said: "It's still early for Aye to come back!"

He suddenly noticed his mother raising her eyes to look outside the palace, and slowly turned back.

The emperor was outside the palace, looking smiling, but Li Laoer felt that it was best for him to disappear at this moment.

"Aye, grandma, I'm going to bed."

Li Laoer ran away.

Zhou Ning got up and changed clothes for the emperor.

She felt that the emperor's body was a little stiff, so she asked: "But you feel unwell?"

The emperor shook his head, "I have something to do, Aning."

"Say." The queen untied his coat and put it aside.

The emperor turned around and looked at her, "Do you know a medicine that can make people irritable and have murderous intentions?"

"There are many drugs that can make people manic and restless, but murderous intent cannot be induced by drugs." Zhou Ning said.

"Oh!" the emperor thought thoughtfully.

Later in the evening, as the couple lay in bed, the emperor whispered about the previous interrogation.

"The medicine for mania... has a bit of a taste." Zhou Ning leaned beside the emperor, "If so, it must be given in a soup with a strong taste."

"That's right, then Wang Mo must be someone else's spy."

"It's remarkable to be able to lie dormant like this." Zhou Ning suddenly thought of Han Shitou and sighed: "When will the people in the palace be less scheming?"

"Only if you can stay awake before power can you have such a possibility."

"Wang Mo is a dead man. By the way, where is the kitchen?"

"Afterwards, the emperor cleaned the kitchen, but found that the matter had nothing to do with the kitchen. The medicine was given by Wang Mo."

"Then, we have to find out about Wang Mo."

"Yes, Shitou and Yi Niang will cooperate with Jin Yiwei to investigate this matter, go to sleep!"

The emperor closed his eyes, but various images flashed in his mind.

"You traitor, go and kill him!"

"How dare that traitor poison Ye Niang?"

"Kill him!"

"Kill him!"

"Kill him!"

…

The emperor woke up suddenly, only to find that it was a nightmare.

Zhou Ning was still sleeping soundly, but the emperor was no longer sleepy.

He stood up quietly, opened the door of the palace, shook his head at the maid outside, and then closed the door behind him.

The moonlight was very cold, and the emperor walked to the steps and sat on the ground.

"Your Majesty." Qin Ze came over after hearing the news, worried that the emperor would catch cold.

"Stop quarreling with me."

"yes!"

The emperor was sitting there, wondering what he was thinking.

"Zitai!"

The queen woke up and found the emperor.

The emperor turned back and said with a smile: "I have eaten a lot of meat these days, and I am a little tired and hot, so I can't sleep."

The queen didn't ask, walked to sit next to him.

"Aning!"

"Um!"

"This matter must be the plan of the pseudo-emperor and his son, but there must be someone outside cooperating with it."

"Yes. There are several drugs that can make people manic. There is only one that may not hurt people and can go unnoticed."

"Which one?"

"Santo!"

There was a cold wind blowing, and the emperor turned around, and Qin Ze handed him a cloak. The emperor wrapped the two of them together in the cloak, "Are there many mulberry vines?"

"I remember that this product is produced in the south. Which book records..."

"I will send someone to find you tomorrow."

"I remember that book was in the palace."

"Then go now?"

"good!"

The couple wrapped themselves in large cloaks and went to Zhou Ning's library hall.

Open the door of the palace, and there are bookshelves inside.

"I have to look hard for it."

Zhou Ning was rummaging around on the bookshelf while thinking about it.

"Is it this volume?" the emperor asked, holding a volume of medicinal materials.

Zhou Ning looked at the title of the book and said, "No."

"Is it this one?"

"no."

The two chamberlains held candlesticks beside them, the candlelight flickered, Zhou Ning frowned in thought, and the emperor's eyes turned, searching...

"I remember it was put together with a roll of first aid prescriptions. Where are the first aid prescriptions?"

"I think you should number your books and sort them into categories."

"But I'm so busy."

"Yes, go back and ask someone to help you!"

"I remembered."

Zhou Ning clapped her hands, turned her eyes, walked to a bookshelf, stretched out her hand and slowly scratched the books...

"Here...here!"

Zhou Ning took out a scroll, and the emperor came over, waved, and took the candlestick from a chamberlain.

The two looked side by side.

Zhou Ning rummaged slowly.

"Here! Mulberry vine is a specialty of the Southern Zhou Dynasty. It can be used in conjunction with aconite and other medicines to boost Yang Qi, so it is often used on dying people..."

The emperor nodded, but he didn't understand.

Zhou Ning tilted her head and looked at him, "Aconite can be used to destroy Yang and collapse, and Mulberry Vine has a more powerful effect. It can forcibly boost vitality, but it should not be used too much, as it can make people crazy."

The emperor pretended to understand, "So, San Teng, can you use it?"

Zhou Ning shook his head, "I've never seen it before, and it can't be found on the market."

"Southern Zhou..."

The emperor pondered and suddenly saw the following line of words.

"Grinding mulberry vines into powder and drinking it can revive the dead for a moment."

Zhou Ning said: "This so-called dead person refers to a dying person who is dying. If you drink Sang Teng, you can take a breath and let him finish his words. Eh!"

"My lord!" the emperor smiled.

What do ordinary people use this thing for?

Only noble people who are full of secrets and can't let go of the glory and wealth in this world can use this medicine.

"But if there are more, the people will be happy to use them!" Zhou Ning said, "It's good to let your relatives live a little longer."

"The explanation is quite sparse." The emperor knew it by heart, "I will send Nianxu into the palace tomorrow, that's all. I'm afraid that letting him in will scare others, so I'll go there. You go back to sleep quickly."
