Yuwenhao was so anxious that his mouth was bubbling and he couldn't eat anything. Seeing that Yuan Qingling was not so painful, he took Tang Yang and Xu to investigate.

He has already been guarding the situation, but he still asks people to take advantage of the loopholes. Why don’t he be so anxious that he smokes?

After all, I have been the prefect of Jingzhao. Although I have not been in office for a long time, I still understand the basic process of handling cases.

All the food Yuan Qingling ate has been checked, but the source has not been traced yet.

The court distributed most of the ingredients in the royal palace every day.

The Chu Palace gets 30 kilograms of pork and 20 kilograms of mutton every day, and the rest of the rice, grain, fruits and vegetables are not allowed. First check the ingredients in the palace, and there is no problem.

Then I checked the source of the purchase outside and asked people directly, but there were some things that were short of weight. If I said that I was poisoned and fooled, I would definitely not dare.

Moreover, the imperial doctor said that Yuan Qingling was not poisoned.

After investigating everything, nothing was gained. Yu Wenhao returned to the mansion, was depressed and angry. Tang Yang ordered someone to serve tea. Yu Wenhao took a few sips, looked at the green tea soup in the green water, and suddenly put it down, his eyes flashed slightly, and said, "There is still nothing to check, the water source."

There are two wells in Fuzhongtong, one for cooking, eating and drinking, and the other for daily use.

However, the kitchen will store some water in the water tank first. When you need to use it, you will directly fetch water from the water tank, so there is no need to go to the well just to do it.

Yuan Qingling has a private water tank. Because she needs special attention to her diet, the lids of other water tanks are often lifted and easy to get dirty, so she can use a separate water tank.

Xu Yi opened Yuan Qingling's water tank and looked carefully. He saw that there were many banana leaves under the water tank.

Because the color of the water tank is coppery yellow, after soaking in water, the color of the banana leaves fades green and slightly yellow. In addition, his nanny's eyes are blurred and he did not see clearly when taking the water. Therefore, he didn't know that there were banana leaves inside.

Xu Yi reached in and stirred for a while, and saw that there were still many peach blossoms under the banana leaves.

Doctor Cao followed him. When he saw the banana leaves and peach blossoms, he was shocked and his eyes suddenly became striking. "Oh my God, no wonder the princess's pulse is so weak and cold. She actually used banana leaves and peach blossoms to soak in water."

Yuwenhao didn't understand pharmacology and asked, "Will this banana leaf soaked in water cause vomiting and diarrhea?"

Yudian Cao paused, "My good prince, banana leaves are cold in nature, peach blossoms have the effect of deficiency, cold and dysentery. The two are mixed together. It's okay for ordinary people to use them, but the princess can't do it. Even if it's not a tormented potion, it won't work, because she had taken Zijin Decoction earlier. Prince, Zijin Decoction is a big deficiency, which damages the lungs and liver. The princess cannot take good care of her and get pregnant. Her physical condition is weaker than that of ordinary people. Now it's difficult to eat and drink, and her blood and energy are not allowed to continue. If you use such drugs that are strong, weak, cold and strong, how can you avoid abdominal cramps? If it's more serious..."

Doctor Cao didn't dare to continue talking, but his face turned pale and his body trembled.

Yu Wenhao's heart was squeezed, "What will happen if it is more serious?"

Doctor Cao had more white eyes than his eyeballs, as if he rolled his eyes and was about to faint at any time. "If it was more serious, he would have one corpse and four lives!"

"Bold!" Yu Wenhao was furious and shouted fiercely.

Doctor Cao was already shaking like a dangerous wall. Yu Wenhao roared, and he became weak and knelt down, "Don't calm down!"

Yu Wenhao was furious, "I am angry and checked, Xu Yi, Tang Yang, check it out for me, see who put these things down?"

There are only a few people who can enter and exit the kitchen, so it is not difficult to investigate.

In fact, there is no need to investigate, because the little beggar Hu Ming secretly saw someone put in, and the man was cook Zhou Gui.

Zhou Gui was the chef who was sent to the mansion by the old lady in the mansion, saying that he was specializing in the food and food of Yuan Qingling.

In the early stages of Yuan Qingling's pregnancy, the food he made also satisfied Yuan Qingling. At least, she could eat a few bites. After all, she vomited to death in the early stage.

Without much torture, Zhou Gui admitted it and said that it was instructed by the old lady of Jinghou Mansion.

This was reported to Yu Wenhao's ears. Yu Wenhao didn't believe it, so he interrogated himself and even used a great punishment. Zhou Gui just bit him to death. It was the old lady's order. As for why the old lady gave such an order, he said he didn't know, and he just followed the old lady's order to do it.

However, it was obvious that the old lady had never been to the mansion. Even if the old lady gave her an order, she would ask someone to pass on the message.

Following the clues, I found the person who went to Jinghou Mansion. The person who passed the message was A Quan, the old servant who served in the old lady's house.

Coincidentally, Aquan had already returned to his hometown two days ago. It was the old lady who gave him grace because of his old age.

Yuwenhao ordered someone to ask, it was indeed the old lady who asked him to return home in person, which made Yuwenhao suspicious.

He least hopes to be the old lady.

Because the only reliable and trustworthy person in Lao Yuan’s family is the old lady.

Her parents are both heartless.

Moreover, Lao Yuan also loved filial piety to the old lady. If she knew that the old lady asked someone to harm her, I was afraid that there would be only a trace of her life.

Yuwenhao then ordered the confidentiality and went to the old lady to ask.

Yu Wenhao felt particularly complicated when he stepped into the old lady's yard.

He accompanied Lao Yuan to see the old lady. It was hard to believe that the kind and majestic old man would harm his granddaughter.

There was a piece of land in the old lady's yard with several banana plants planted. In early March, the banana leaves were green, so green that they thorn Yu Wenhao's eyes.

"The prince is here?" Sun's mother walked out and saw Yuwenhao standing in the yard and staring at the banana tree steadily. She hurried forward to salute, "I see the prince. The prince is here, why don't you ask someone to report it, so that I can greet you."

Yuwen Hao's eyes were faint, "Is the old lady inside?"

"Hey, I'm making small clothes." Mother Sun said with a smile.

She led Yu Wenhao in. A stove was growing in the room, and the doors and windows were slightly opened. Although the wind blowing in was cold, it was not bone-bone, and it was a little drunk.

The old lady sat cross-legged on the Arhat bed, fiddling with a small dress in her hand. Her movements were very fast, and she flew up and down, and a row of needles and threads fell.

There are a few ready-made clothes next to them, which are small and cute, making people feel happy when they see them.

However, Yu Wenhao couldn't be happy.

He looked at the old lady and raised her head. Her eyes were a little stunned, but then she looked tight, her feet moved down, and she said anxiously: "Have you acted?"

Mother Sun hurried over and helped her up and said, "Don't worry, if you act, why would the prince come? He must be guarding the princess."

The old lady's expression relaxed, "Okay, it's not just about moving now. It's best to have more days in her belly."

She looked at Yu Wenhao and saw that his expression was strange. She remembered that he had ordered someone to ask A Quan before. Then she knew that something might have happened, so she asked him to sit down and asked, "Is there anything wrong?"
