Seeing her close her eyes, Rong Zhen held her hand tightly, slowly laid her down on the bed, and tucked the quilt for her.

When Doctor Hu saw him walk to the door without saying a word, he immediately went forward to greet him. Knowing that the prince had something to ask, he stood in front of him respectfully.

“Your Majesty…”

"Is there any way to make her stop vomiting?" Rong Zhen felt so distressed when he saw her vomiting out even the acid in her stomach. He wanted so much to share her pain.

Doctor Hu had never come across such evil things before, and was at a loss for a moment.

"My Lord, please be patient, the princess will be fine."

"What a peaceful life! If you can't cure her, I will force you to eat those bugs."

As soon as Rong Zhen finished speaking, he was frightened to the point of trembling with fear.

"No, Your Majesty. I am old and cannot stand this kind of torture." Doctor Hu cried in front of him, fearing that the prince would ask him to eat those worms.

"Enough, I was just fooling you, but I didn't expect you to be such a coward." Rong Zhen snorted coldly with contempt and displeasure in his eyes.

The trees in the yard rustled in the wind, but at this moment he felt something unusual surging in the yard.

"You go back first. I will find you if I have anything to ask."

Rong Zhen knew that the pair of eyes nearby had followed him back to the palace, and they were quite curious about this man's identity. After Doctor Hu quickly left with the medicine box, the wind in the yard suddenly calmed down.

"Who is it?" Rong Zhen's eyes were like black holes that could swallow everything. He stared at the movements nearby and finally saw someone show up.

"Gongsun Ningxue." When Rong Zhen saw this person, he called her by her name. Unexpectedly, it turned out to be Gongsun Ningxue.

On the other side, Xie Changming's men followed Gongsun Ningxue's clues, found Prince Zhao's Mansion, and ambushed nearby. If they found Gongsun Ningxue, they would have to kill her to silence her if necessary.

"King Zhao." Gongsun Ningxue walked up to him and saw that he looked worried, thinking that he must have encountered some big trouble.

"You escaped?" Rong Zhen thought about the noise when he returned home. He thought that Gongsun Ningxue had been following him carefully, but just didn't show up in time.

"Well, King Zhao, please save the brothers in Jianzhong."

Gongsun Ningxue is a proud person and she never asks for help easily, but she is desperate at the moment. She believes in Rong Zhen's character. That time on Qingshi Mountain, Rong Zhen's behavior completely moved her.

"The imperial court is at Sword Tomb One, you don't have to worry." Rong Zhen placed his hands casually behind his back, and at this moment, pairs of eyes on the roof began to glow.

They secretly pulled the crossbow and shot at Gongsun Ningxue. Rong Zhen quickly pulled Gongsun Ningxue's arm and dodged the hidden arrows. It was safest to bring Gongsun Ningxue back to the house. Qingfeng heard some movement on the eaves, so he brought people to investigate. After seeing a few clear footprints, these people disappeared without a trace.

"Damn it, take some people over there to check!"

"yes."

Gongsun Ningxue took a deep breath and noticed Princess Zhao lying on the bed. She frowned and walked towards her, "What happened to Princess Zhao?"

"She was poisoned." Rong Zhen's tone was quite calm, but his heart was in turmoil. If the mansion had not been attacked that day and Gu Yunru had not stood behind him, the poison in his body would not have developed so quickly.

"I can see that you seem to have lost a lot of weight since that day." Gongsun Ningxue knew some medical skills and put her hand on her pulse. This action caught Rong Zhen's attention and he walked towards her quickly. "Do you know medical skills?"

"Of course, as a descendant of the Gongsun family, I can do anything." Gongsun Ningxue's eyes were filled with confidence, but now even the Gongsun Mansion has fallen into decline, so what qualifications does she have to show off?

A trace of sadness flashed across his eyes. After taking her pulse, he found some abnormalities. He was afraid that this poison could not be cured by ordinary medicine.

"What's going on?" Rong Zhen was now shrouded in despair. If there was a glimmer of hope, he would feel extremely excited.

"No, the person who tied the bell must be the one to untie it." Gongsun Ningxue knew that the poison was introduced from the Western Regions and was prevalent in Miaojiang. If they wanted to find an antidote, they had to find the person who put the poison in their territory.

"Your Highness, have you found the person who put the poison on you?" Gongsun Ningxue asked with a frown.

The night was quiet, with only the lights in the house shining. Rong Zhen frowned, and seeing him like this, Gongsun Ningxue understood that she had not found the person who had cast the poison.

"I do know where someone is doing this kind of business." Gongsun Ningxue's words caught Rong Zhen's attention. He quickly moved his gaze to her and asked, "Do you know where it is?" Gongsun Ningxue smiled but didn't say anything, as if she was pretending to be mysterious. Rong Zhen came in front of her and asked again, "Where is it?"

"Why is your highness the Prince Zhao in such a hurry? We need to sit down and discuss this matter slowly. Gu is a taboo in Da Qi, and no one dares to show up to trade. So naturally, there are people doing this business in some extremely hidden places."

Gongsun Ningxue seemed to be very knowledgeable about this. It turned out that when she was a child, she saw her grandfather doing a business with an old Taoist priest. However, the poison was not meant to endanger people's lives. Instead, that day, the housekeeper of the mansion was frightened for some reason and seemed to be possessed by evil spirits. Fortunately, the old Taoist priest took a poisonous worm and fed it into his mouth. Looking at the squirming fat worm, Gongsun Ningxue was so scared that she couldn't eat for several days. But she didn't expect that the housekeeper really got better.

"But I never saw that old guy again after that. He had a lot of silver on him and didn't look like he was from the Central Plains. He came here because of my grandfather's friendship. I heard that he saved my grandfather's life many years ago, but that was a long time ago."

Gongsun Ningxue recalled these past events, and her eyes became moist again, thinking of her grandfather's doting on her, leaving her with everything good. Her parents died early, but she was able to thrive under her grandfather's care. No one dared to go against her wishes. She was arrogant and domineering since she was a child, and she didn't make many friends.

Seeing Gongsun Ningxue crying unconsciously, Rong Zhen seemed to be moved and handed her a handkerchief. Gongsun Ningxue thanked her casually, wiped her tears, turned her head and looked at Gu Yunru who was lying on the bed without any expression.

"Your Majesty, may I ask when did the princess discover the abnormality?"
