When Huai Jin thought back to how he and Yuwen Fei had first been knocked unconscious when they entered the room, and then sent over by the person in front of him, it could be seen how important this place was to Yuwen Jue.

Without even asking who the hairpin was, it was just a big problem how to send the hairpin into Su Geying's hands.

Huai Jin also frowned, her chest feeling a little stuffy, she stood up and also walked outside.

Huai Jin looked at the vent, and suddenly had a bold idea. She turned around to look at the blue clothed man, "Where does this vent lead to?"

The blue robed man pointed outside and replied, "The main hall."

"You suspect that someone used the air vent to bring the hairpin over?"

Yuwen Fei had already guessed what Huai Jin was thinking, but that air vent could not be used to allow one person to pass, and even if someone used a method to send the hairpin over, how did he manage to enter the hall?

"When it was just one hour ago, Esteemed Empress Dowager suddenly went there once."

Yuwen Fei suddenly thought about what the Vermillion Bird said last night, and asked again: "Last night, when we were at Hai Yi, did you open any air vents?"

The blue clothed man nodded, "Every day at the Hai hour, the air vents will open up for two hours to conduct ventilation."

It had to be said that all of this was too much of a coincidence.

Huai Jin raised her head and looked at the air vent, without staying any longer, she turned and walked out.

Yuwen Fei shrugged and followed behind Huai Jin. It seemed that she was going to be used as a gun again.

As she had been holding it in her arms all this time, the snow sugar had slightly melted. A corner of the sugar paper had turned slightly yellow, and there was even some dust on it.

Yuwen Fei picked up the book of poems, looked at the snowflakes candy and frowned, then got up and kicked it away.

"Squeak squeak squeak ~ ~"

The straw at the corner of the wall shook as a mouse drilled into the corner, dragging the piece of sugar to the corner as it enjoyed its meal in comfort.

Huai Jin only heard the sound of their voices and sighed in her heart. After the hygiene in the ancient prison was terrible, the blue clothed man had to send the two of them to the small room that they had just entered.

As expected, Li Changde was still waiting outside when the two of them came out of Cloud Locking Pavilion.

Huai Jin went to check around the hall first, and sure enough, there was a wall behind every bookshelf. The color was a little darker than the surrounding walls, and the size was also only the size of a fist.

After Li Changde brought the two of them out of the Cloud Locking Pavilion, they arrived at the imperial study.

In the imperial study, Yuwen Jue was flipping through a memorial paper. On it was a gift from the Heavenly Monarch, and it was written for him to choose from the dates Ping Yang would be buried in.

The closest date was three days later. Yuwen Jue's right hand kept hitting the closest date, hesitating.

"Your majesty, Seventh Prince and Princess Anping have arrived."

Li Changde's voice came from outside the house. When Yuwen Jue came back to his senses, he closed the imperial edict and called out for the two people to come in.

"Have you found anything?" Yuwen Jue raised his empty hand, avoiding the two people's salute and directly asked.

Huai Jin frowned, she sat down on the chair as if she was discouraged, and said with grief: "That Cloud Locking Pavilion, is like an iron wall. I really can't imagine how that hairpin was sent in."

Yuwen Jue chuckled as he looked at Yuwen Fei.

However, Yuwen Fei kept quiet on the matter, he took out the book of poems from his bosom, placed it on the table, and shook his head: "royal father's job is really hard, I do not need this book of poems written by Elder Xun. You'd better do it another way. "

Seeing this book of poems that Yuwen Fei had taken away without permission, Yuwen Jue was also not surprised. He only flipped open the book of poems, and after reading it once, he sighed. Old Mr. Xun's calligraphy skills are really something to be reckoned with. "

Yuwen Fei could not deny it, if not for that, Dong Li that old fellow would not have kept pressing him to get the thing.

"What else do you want?" Hearing Yuwen Fei's words, Yuwen Jue knew that he understood his own intentions.

Yuwen Fei muttered to himself for a long time, and finally looked at Huai Jin, who was at the side, and suddenly said: "How about you betroth me to An Ping?"

The two of them were stunned when they heard this.

Yuwen Jue regained his senses and slapped the table: "Nonsense!"

Huai Jin's identity had always existed in an awkward position in the capital. Seeing that Huai Jin was getting older, and had long since passed the age of one to leave the pavilion, Yuwen Jue, on the other hand, could not return her to the Xuanping Marquis, nor could he casually marry her out.

Originally, Huai Jin had acted rashly, making everyone in the capital fear him from head to toe. He was also happy to see such a situation, but she didn't know why, but this Princess Anping had become so popular today, begging him to marry her one by one.

Yuwen Fei clicked his tongue, and said unhappily: "Why do I have to be joking when I say that I want royal father to betroth the marriage, when Prince Jin asks for royal father to betroth the marriage, is that true?"

With a headache, Yuwen Jue closed his eyes and started to ponder whether he was right to ask Yuwen Fei to intervene in this matter.

Back then, he had ignored the Empress Dowager's objections and made the Wen Family's daughter the empress. The empress dowager was furious at this point, and Yuwen Jue had no choice but to invite the Xiao Family's daughter into the palace. However, that girl had had difficulty giving birth during childbirth, and died after giving birth to her son.

Ever since the child was born, it seemed like it knew how much of a disaster its arrival brought to its mother. It kept on crying and no matter who coaxed it, it would not improve.

After the full moon, the child was raised by the empress dowager and raised in the Jin Mansion. Although the relationship between the Jin Mansion and the empress dowager did not appear close on the surface due to the child, Yuwen Jue still considered the Xiao family's power behind the empress dowager to be behind the Prince Jin.

Even the brazen and unscrupulous Crown Prince Yuwen Lie, who was dressed in martial arts, had the support of the Crown Prince's Concubine Wang family behind him.
