Li Yuyan said solemnly: "Big brother, last night my Royal Highness and I visited the palace of the concubine at night and found a few letters, all of which were written by the father of the Yaozhou assassin to the concubine. The letter mentions that the task has been completed, although it is not written what the task is, but according to the time of payment, it is almost the time when Sister Wu'er had an accident."

Hearing this, Li Yuye's handsome face sank suddenly: "What did Your Highness say?"

Li Yuyan said: "His Royal Highness is thinking about the concubine's motives for harming people, and now if you can find the letter written by the concubine to the father of the Yaozhou assassin, I believe the truth will be revealed."

Li Yuye bowed: "It's a pity that my people went to Yaozhou with the people of the East Palace to investigate, but they couldn't find the letter."

"Yaozhou is a city, and if the letters are hidden deeply, it is indeed difficult for outsiders to find them. I said earlier that the father of Yaozhou destroyed the letter, but I don't think so. Because the concubine in the palace was once married to him, and they still exchanged letters a few years ago, which shows that they have a deep affection."

"Sister, you really make sense when you say that."

"Big brother, do you know where I found the letter with Your Highness?"

"Where?"

"In the dark under the spiritual seat of the concubine's son."

Li Yuye suddenly laughed: "Hidden enough."

Li Yuyan looked at Ye Jiu: "Sister-in-law, do you know that the concubine is in her own bedroom, why doesn't she live in the main hall, but in the side hall?"

Ye Jiu shook his head: "I used to have this question, I don't live in the main hall with a good body, and I live in the side hall, but no one knows why."

Li Yuyan guessed: "When the first emperor was there, he came to the palace of the concubine, and naturally stayed in the main hall overnight. After the first emperor left, the concubine finally got rid of the first emperor. What she thought about in her heart was the man in Yaozhou, so she moved from the main hall to the side hall. As for now, she has not slept all night, ostensibly speaking with her son's spiritual position, but in fact she is talking to the letter that is placed in the secret grid, sending her thoughts from afar."

The woman in the palace gave her body to this man, but her heart was thinking of another man.

This may be the real reason why the concubine didn't sleep all night.

"Can I think so, the concubine actually hated the first emperor, because of hatred, she wanted to sacrifice her love with Tiansheng's country, so she secretly provoked a dispute between the Zhenbei Wangfu and the Heavenly Family?" Li Yuyan's expression was serious, "Big brother, I guessed boldly, I don't know if it's right?"

"Possibly! It seems that Yaozhou has to go again." Li Yuye said, "When the little thieves in the military camp are dealt with in the past two days, I will discuss the trip to Yaozhou with His Highness."

"Okay." Li Yuyan bowed his head.

--

After having dinner in the Zhenbei Palace, Li Yuyan returned to the East Palace.

As soon as he returned to the dormitory, seeing that there was no one in the bedroom, Li Yuyan asked the eunuch who was waiting, "His Royal Highness is still working?"

The eunuch said respectfully: "Back to the crown princess, His Royal Highness the crown prince and the little grandfather are still in the study to discuss important matters."

Li Yuyan nodded, someone seems to be very busy today.

Thinking that it was too late, she asked again, "Has Your Highness had dinner?"

The eunuch bowed: "Yes, but I don't eat much."

Hearing this, Li Yuyan lifted her skirt and left the dormitory and went straight to the dining room.

She took a few snacks in the dining room and packed them into food boxes, and she personally sent them to the study of the small building.

At this moment, in the study of Xiaolou, Jiang Lecheng stretched his waist and put down the pen in his hand: "Your Highness, we have been busy all day today, will we be busy tomorrow?"

Ye Yiheng held the pen and wrote, without raising his head: "You go home."

The busier he is today, the more he can accompany Yan Yan wholeheartedly tomorrow!

"Really? The minister went back." Jiang Lecheng stood up, walked a few steps towards the door, and said, "Your Highness, it's not a problem that you're so busy, you always have to rest!"

Ye Yiheng said lightly, "Get out of here."

Jiang Lecheng bowed: "Come on, roll away."

While speaking, he strode towards the door of the study, and before he stepped out of the threshold, he saw Li Yuyan carrying a food box to meet him.

"The crown princess is here, and she brings supper." Jiang Lecheng smashed his mouth, turned his head to Ye Yiheng and said, "Your Highness, the minister can wait and then return to the house."

Li Yuyan smiled and said, "I heard that you didn't eat much for dinner, so I took a snack from the dining room and ate some more."

"I didn't eat much."

Jiang Lecheng took the initiative to lift the food box in Li Yuyan's hand, put it on the other side of the table, opened it immediately, and put out the plates inside one by one.

Ye Yiheng saw that she really came back, and her face, which had been cold for a day, finally had a smile: "The palace is late for dinner today?"

The implication is that she came back late.

"I talked a lot with the eldest brother and the second brother, and the situation of the sister-in-law, you know, I'll stay longer." Li Yuyan picked out a few pastries and put them on a small plate, and sent them to someone's desk, "Your Highness is angry?"

She picked up a piece of pastry and handed it over.

Ye Yiheng watched her slender fingers pinch the plum blossom-shaped pastry, although the pastry was beautiful, but it couldn't reach her fingertips.

"How can Lone be angry?"

As he said this, his thin lips lightly opened and ate the plum blossom cake.

Jiang Lecheng raised his eyes to look at the bookshelf and then at the ceiling, he didn't seem to be very suitable here, but he was hungry.

At dinner, for some reason, the prince didn't have much appetite.

The prince has no appetite, so he naturally has no appetite for this accompaniment.

Although his identity has changed now, he has long been a courtier of the East Palace, but he is accompanied by the prince for one day and the prince for life.

The prince couldn't eat, so he naturally had to pretend that he couldn't.

At this time, he saw that the prince ate a piece of pastry handed over by the crown princess, and he hurriedly took the same pastry, in view of Li Yuyan's presence, he was bolder, and he always felt that His Royal Highness the prince would not be angry with him in front of the crown princess, so he ate and stuffed it violently.

In the blink of an eye, a plate of plum blossom cake disappeared.

Jiang Lecheng burped, stood up and bowed: "Two highnesses, the minister has taken his leave."

When he straightened up, he hiccuped again.

Ye Yiheng glanced at him: "Didn't you let you go earlier?"

"Yes, yes, yes!" Jiang Lecheng took a few steps back and hurriedly left the study.

Thinking of the rare smile on the face of the prince of Fang Cai, Jiang Lecheng couldn't help but sigh, it was really good to have a wife, and it seemed that at this moment he understood the old man's good intentions.

With a wife by his side, he knows the cold and asks for warmth, and his life is beautiful!

In the study, Li Yuyan looked at the stacked folds and documents on the bookcase, and couldn't help asking, "Are there so many things to deal with?"

Ye Yiheng said "um": "Yes, the old man sent a lot of twists and turns, plus there are already a lot of affairs in the East Palace, so I can't sleep until late tonight."

Hearing this, Li Yuyan thought, if he sleeps late tonight, will it affect his performance tomorrow night?

Thinking of this, she couldn't help but ask, "Do you want me to help His Highness stew a tonic and replenish his body first?"

Ye Yiheng laughed loudly: "Replenish your body?"

Li Yuyan blushed slightly: "Well, don't you need to make it up? Your Highness has so much business to do tonight."

"Yes, the crown princess has not experienced it herself, and it is normal to have this question." He stretched out his arms around her waist and asked in a low voice, "Or does the crown princess want to have more times tomorrow night?"
