"Cough, cough!" Yuwen Fei looked at the two of them and coughed loudly, trying his best to attract Huai Jin's attention. Seeing that Huai Jin was ignoring him, he directly opened his mouth to ask: "Why didn't you ask me?"

Huai Jin was speechless. Looking at his proud expression, she asked snappily: "Then do you know how to cook?"

At the same time, he was also uncontrollably upset. Why was he moved by Yuwen Fei's order badge earlier, he should have insisted on having Yun Jing give it to him!

Yun Jing, who rarely spoke, fled as if he had escaped after leaving those words. What made him flee was not only Huai Jin's blazing gaze, but also the waves of coldness that came from his side.

Towards his bold words and ambition, Huai Jin could only chuckle.

Today, because of the protection of Zhao Mo and the others, the entire Princess Mansion was like an iron wall. On the second day, as if afraid that the two would not take the initiative to investigate, Yuwen Jue sent Wei Chengwu to guard the front door of Princess Mansion early in the morning.

Huai Jin had only just eaten breakfast when she saw Ran Mei hurriedly returning from the front hall.

"Princess, Captain Wei is waiting in the front hall."

"What is he doing here?" Huai Jin did not understand, and continued to eat the food on the table. It had to be said, Yun Jing's culinary skills were indeed good.

"The Captain Wei has said that he will personally escort the princess and the Seventh Prince to the Grand Princess Mansion."

"Oh?" Huai Jin raised his eyebrows. Personal escort? She was probably here to urge them on.

Huai Jin did not react, she took another sip of the porridge and looked in the direction of the Purple Bamboo Courtyard, then asked: "Where is the Purple Bamboo Courtyard?"

Ran Mei shook her head, she had also sent people over to notify him, but there were still no movements.

Huai Jin understood, and replied indifferently: "Then let him wait."

Although she and Yuwen Fei had been ordered by the emperor to investigate this case, if they were too attentive to this case, it would make them uneasy. Therefore, the two of them tacitly agreed that it would take a very long time for them to finish their breakfast.

Just like this, Wei Chengwu wandered around the antechamber. After waiting for half an hour, he still did not see either of the two people.

When he finally couldn't wait any longer, the two of them slowly walked out one after another.

Wei Chengwu did not dare delay, and immediately informed the two of his purpose, bringing the two of them to the carriage, and sending a group of people to protect his body, he then led his horse and lead the way.

Just like this, a group of people majestically walked towards the Grand Princess Mansion.

Inside the carriage, Huai Jin lifted up the curtain of the carriage to look at Wei Chengwu. She suddenly turned around and asked Yuwen Fei: "How do you know that Princess Ping Yang has Qishan white jade on her?"

Once Huai Jin understood the importance of Qishan white jade, she wanted to ask him.

Initially, she thought that because of this Qishan white jade, Ping Yang was somehow related to the Treason case, but Yuwen Fei told her that it wasn't so.

Furthermore, from the short time Huai Jin had interacted with him, she felt that Ping Yang could not be such a person. Then, how did she obtain this piece of Qishan white jade?

Yuwen Fei sat in the car, holding onto his fan as he spoke slowly: "I found it by chance."

"Then where did Ping Yang's Qishan white jade come from?" Huai Jin continued to interrogate him.

Yuwen Fei saw that she was looking at him like he was interrogating a convict, and for some reason, felt a little irritated in his heart. The fan in his hand suddenly slapped his hand, and produced a clear sound: "I don't know either."

Indeed, he did not know, that when he found out that Ping Yang had Qishan white jade, he sent people to investigate, but the people behind him were meticulous and did not let him find out anything.

On the following day, Ping Yang passed away in the palace feast, something that he did not expect. With Ping Yang dead, if the things around Ping Yang were to be sent to be buried along with him, it would be even more difficult to trace the Qishan white jade.

Huai Jin looked at him for a long time. After confirming that Yuwen Fei was not lying, he lowered his head and started to think.

For a princess in her room, how could there be a Qishan white jade that was as strong as an enemy?

Huai Jin thought about it for a long time, but still couldn't understand.

In front of her eyes, it was as if there was a boundless fog without any clues. And this feeling was the one she hated the most.

After a moment of silence, she asked again, "What you wanted me to find was a jade pendant, how did it become a jade hairpin?"

Seeing her serious expression, Yuwen Fei straightened his body and replied: "I found out. It was Ping Yang who sent people to separate the jade pendant, creating a whole set of faces to deal with it. It must have been left with this hairpin before it died."

"What about the jewelry that was taken care of before?" The more Huai Jin asked, the more questions she noticed.

Yuwen Fei shook his head, indicating that he did not know either.

It was very obvious that there was still someone behind Ping Yang's back. No matter whether it was the origin of the Qishan white jade, or the direction that she would head to later on, there was definitely a connection between this person and herself.

Huai Jin was lost in thought for a moment. The Qishan white jade case in front of him was something that had no beginning or end. However, the empress dowager and emperor were urging the two of them from behind, so they had no choice but to investigate. Furthermore, she had to give the empress dowager an explanation for Princess Ping Yang's death.

The carriage moved forward slowly, Huai Jin was also immersed in her own thoughts, trying her best to pull some clues out of it. Outside, the sun shone through the curtains and onto her deeply furrowed brow.

Yuwen Fei glanced at her, yawned comfortably, and knocked the fan down forcefully. For a moment, the area he had hit swelled up, and his brows relaxed.

Huai Jin rubbed her forehead, some anger in her eyes: "What are you doing now!"

Yuwen Fei kept his fan and closed his eyes, his body slanting down with a satisfied expression: "Why are you thinking about it so much now, when we reach Princess Mansion, it's not too late for you to investigate."

The carriage stopped at the entrance of Wuan Lane after a period of time. In the Wuan Lane, there was an unwritten rule that carriages were not allowed to enter the alleyway in order to avoid colliding with important people.

The two of them were helpless, after getting off the horse carriage, they walked towards Grand Princess Mansion, who was not far away.

Wei Chengwu also got down from his horse, and followed the two of them closely.
