In the evening, the prince's mansion.

Ye Yushen was scribbling on a map made of cowhide with his head down, and drew a circle in the northernmost position for a long time. Then he looked up at Ye Yugui, who was reading a book unhurriedly on the side.

"Seventh brother, you will leave the palace early tomorrow morning. Isn't there anything to prepare? Ye Yushen has always been unable to hold his breath, and he was reprimanded by the emperor for this, but this problem can't be changed, and now he looks at Ye Yugui's flat face, and he can't help but feel anxious when he is still reading a book in a hurry.

Ye Yugui listened to Ye Yushen's words and gently closed the book in his hand, and the corners of his mouth raised lightly to ask Ye Yushen, who was frowning tightly at the moment, with a pair of thick eyebrows, and his tone was still calm and slow: "His Royal Highness the Prince, you can know what kind of book I just read." ”

Ye Yushen felt inexplicable, so he said in a deep voice: "When is it, Seventh Brother don't play a guessing game with me here." ”

Ye Yu raised the book in Yang's hand, and then said slowly: "I read "The Art of War". ”

"The Art of War? Seventh brother, what's the use of reading the book of soldiers now, I didn't ask you to go to war this time. It's to negotiate, I really can't rest assured about your appearance, or I'll send someone else to go someday. Ye Yushen was quite worried in his words, and because he had stayed up late for several days, he was staring at the dark circles under his eyes at the moment, and he looked very bad.

Ye Yugui didn't get angry at all when he saw Ye Yushen say this, but then smiled: "Who said that watching "The Art of War" is to fight, I just think that some of the words in it are worth careful scrutiny, and they are also very beneficial to me." ”

"Then tell me what's in it." Ye Yushen saw that what Ye Yugui said was also reasonable, so he motioned for him to continue.

Ye Yugui put down the "Art of War" in his hand, which had been turned a little yellow, and his eyes were no longer as casual as before for a while, but with a vague sharpness, and said in a deep voice: "Know your opponent and know yourself, you will not be defeated in a hundred battles: you know your opponent without knowing each other, you will win and lose: you don't know your opponent, you don't know yourself, you will die in every battle." ”

Of course Ye Yushen knew this sentence, this was the most famous sentence in "The Art of War", but what was the purpose of Ye Yugui saying this at this moment, he was puzzled and asked: "Seventh brother, what do you mean by this?" ”

Ye Yugui guessed that Ye Yushen would have doubts, so he replied: "This is the key to this question, we don't know the specific purpose of the people in the north now, and my previous guesses are not sure to be correct, and the north is cold and remote, and we don't know where the specific terrain conditions are, so the army sent before was all wiped out." ”

Ye Yushen nodded, agreeing with Ye Yugui's statement at this moment. And with his head down, he began to meditate as well.

Ye Yugui continued: "This is the so-called ignorance of the other, but relatively we know everything in this capital and know how much combat power the palace army has, so although all the troops we sent to the north have been captured, they have not dared to leave the north rashly until now." This is called a confidant. ”

Ye Yugui was silent for a while, then looked at Ye Yushen, who looked thoughtful, and then asked, "So what does His Royal Highness the Crown Prince think we should do now?" ”

Ye Yu replied heavily word by word: "Know yourself and know your opponent." ”

Ye Yugui picked up the brush on the table, and then deepened the circle drawn by Ye Yushen on the northernmost part of the map: "That's right, so my biggest purpose this time is to know the other!" ”

Ye Yushen still frowned, looking at the circled northern region on the map: "But what are you going to do." How can you gain their trust on your own? ”

"As for what I am going to do, although I am sorry for His Royal Highness the Prince, I can only keep it a secret for the time being. However, Your Royal Highness the Crown Prince, you must know that I am not going to represent me alone, but the entire Great Sage Dynasty behind me. Represents all the children of the royal family and court officials. So they're definitely going to treat me well. ”

Ye Yushen was still worried: "Either I'll arrange a few officials to negotiate with you, or I will pick a few guards with strong kung fu to protect you secretly." ”

Ye Yugui shook his head resolutely: "If I bring someone else, I will definitely make them vigilant, if it is just me, they must not have so many worries." It would be great if I succeeded in negotiating, and it would be best to avoid the best outcome of a war between the two sides, but if I failed to negotiate, I would be able to come back safely, and with my information at that time, we would not lose the war. ”

"Then I can only follow what you said, if you return triumphantly this time, the seventh brother will definitely become the first-class hero of this great victory! But whatever you ask, I will definitely meet you. Ye Yushen promised to speak, and patted Ye Yugui on the shoulder vigorously.

"Okay, today I will write down the words of His Royal Highness the Prince!" After Ye Yugui Langsheng finished saying this, he raised his brush again and crossed it heavily towards the northern region on the map.

At night, the moon is on the top.

In the courtyard of the Hangui Palace, the soft and white moonlight sprinkled on the bright red plum blossom branches that bloomed at this moment. It is beautiful and intoxicating to reflect with the fluffy and wide snow on the ground like cotton.

Ye Yugui was only wearing a thin black practice uniform in a clearing in this Merlin, his ears and hands were red from the cold, but he didn't feel it at all. Still holding a long sword and dancing vigorously, the hilt of the long sword was long, and through the moonlight, it emitted a silver light, and it was not sharp from a distance.

And Ye Yugui's eyes were a little colder than the cold long sword at the moment, and his body stepped forward one by one. The plum tree, which was taller than a man in front of him, was cut off from the middle, and within a moment it suddenly fell to the ground, and the snow on the ground flew up as if it was snowing again.

After waving for a while, all the plum trees within five meters of Ye Yugui fell to the ground, and the plum petals fell all over the ground, looking like a mess from a distance.

He put away his sword, then wiped the sweat on his forehead with his sleeve, and his eyes unconsciously looked at the direction of the palace where Ye Yufu was located across a palace wall not far away.

In the past, there would have been several lamps emitting a soft yellow glow in the palace at this time, but now that the master of this palace is gone, he has taken the light with him.

I don't know what she's doing now, if she's resting.

Ye Yugui thought about it so distractedly, and the hand holding the long sword also became stiff due to the cold weather.

Suddenly, there was a creaking sound of people's feet stepping on the plum blossom branches behind him, and he waved the long sword in his hand and said sternly: "Who! ”

What came out was the man in black who had been elusive beside Ye Yugui, he was not wearing the black night clothes he used to wear at this time, but wearing a simple gray robe, and there was a rare lack of disguise on his face.

This man was about forty or fifty years old, not tall but extremely straight, not like an ordinary man of his age. The face of the Chinese character, there are a lot of wrinkles at the corners of the eyes, and he has a sheep's beard and looks like a very kind middle-aged man.

Ye Yugui looked at him unhappily, and said in a somewhat rushed tone: "Uncle Li, how many times have you said not to suddenly appear behind me." ”

The middle-aged man called Li Bo rubbed his hands that were red from the cold, and then said with a kind smile: "I'm getting older, and my memory is not good, so I won't be next time." ”

If there were people in this Merlin at this moment, they would be shocked, this Li Bo was the eunuch Li Hai, who had been very important by the emperor's side over the years.

"How's the guy you were told?" Ye Yugui received the long sword in his hand to his waist, and then asked in a deep voice.

Lehi lowered his head and said respectfully: "Master, this group of people is quite high in quality and talent, and they will be available in a few months." ”

Ye Yushen nodded with satisfaction: "Thank you for your hard work, I will leave the palace tomorrow, I hope you can supervise them well when I am not in the palace." I'm sure they will come in handy in the future. ”

"That's nature. By the way, I came to the master this time mainly to tell you something. Lehi leaned over Ye Yugui and whispered a few words in his ear.

After Ye Yugui listened, the corners of his mouth gradually hooked up for a long time and sneered: "I actually sent it to the door myself, which will save me a lot of time to find him." ”

Lehi asked, "What is the master going to do?" ”

Ye Yugui thought for a moment, and then came up with an answer: "Tell him that I will go to see him tomorrow, and tomorrow I will let the prince think that I have really gone to the north." After all, it's hard to get out of the palace, so you have to take this opportunity to plan and calculate. ”

"Yes." After Lehi finished speaking, his figure flickered and disappeared into the boundless moonlight.

Again, the clock is this afternoon.

Innis House.

Ruan Tian asked Wu Wei softly if he was still singing this song today. Wu Wei thought for a moment, and felt that he was a little sorry for the princess and Brother Yu today, so he said: "Let's sing, after all, it is very difficult for the princess to leave the palace once, so you can sing a song for her." ”

Ruan Tian nodded, even if Wu Wei didn't say that she would sing, after all, promises and people naturally had to be fulfilled.

When the two returned to the house, they saw Yu Baiyi talking about something, which made Ye Yufu cover her mouth with a handkerchief and laugh, and the smoke on the side was even more happy that her face was a little flushed.

In the house before, Ruan Tian had never seen Ye Yufu's face carefully, but now he was quite amazed when he looked at it like this, how could there be such a beautiful girl in this world, although she was just wearing a blue cotton embroidered dress that ordinary rich and noble ladies would wear, and there were only simple blue beads on her head. But it's still so dazzling.

She has a small face with melon seeds, her skin is as white as snow but ruddy, and a small section of her neck is exposed.

The body is like a willow supporting the wind, and the waist is slender and slender. It's really Ruili's best. She thought that Tian Ningshuang's appearance was already beautiful to the limit, but this woman was not inferior to her. On the contrary, it has more of a mysterious temperament that is elegant, refined, noble, and unparalleled.

Ruan Tian thought to himself that it was only in the palace that could cultivate such a stunning beauty.

She noticed that she was out of shape for a while, and quickly closed her inquiring gaze.

As soon as Yu Baiyi saw Wu Wei coming back, he hurriedly asked, "Why did it take so long to come back, what happened outside." ”

Wu Wei squinted at a few people on the side, and found that no one was looking at him at the moment, so he glanced at Yu Bai and said with a smile: "It's just that two hooligans fought and smashed a lot of porcelain vases and jade." The people have already run away. ”

Yu Baiyi knew what was going on as soon as he looked at Wu Wei's eyes, so he said: "It's okay, Brother Wu, I see that the princess, Miss Ruan and Miss Yan'er are all a little thirsty, why don't you and I go and ask for some tea and fruits." ”

Wu Wei nodded, then turned to Ruan Sun and said, "Ruan Day, you sing to the princess first, and we will go back as soon as we go." ”

Ruan Tian gracefully bowed and replied, "Yes." ”

Then Yu Baiyi said softly to Ye Yufu: "Princess, Brother Wu and I will go back as soon as we go." ”

Ye Yufu didn't speak, just nodded slightly.

As soon as the two came out, they found a hidden corner, and Wu Wei said to Yu Baiyi solemnly: "It was Liao Yunfei, the son of the leader of the northern border, who was fighting outside. ”

After hearing this, Yu Baiyi hurriedly frowned: "Liao Yunfei actually came to the capital." ”

"So I'm now hurriedly talking to Brother Yu about countermeasures, after all, this matter must not be made public."
