When the eldest prince returned to the mansion, he saw Yun Luo's pale face, sitting in the study waiting for him, he was rare and did not get angry, but frowned and asked, "What are you doing here?" Seeing that Yun Luo didn't speak, the eldest prince's patience was almost exhausted: "If you have nothing to do, hurry back to your room!" This king doesn't have time to accompany you! ”

Glancing at the eldest prince with a face full of "I don't have the kung fu to worry about you", Yun Luo raised her head faintly and said: "Knowing that something happened to the border defense, I remembered that I had seen the trump card formation used by the Xicheng army in an ancient book, the Crescent Moon Formation."

The eldest prince looked surprised, and before he could question her how a woman could talk about state affairs, Yun Luo lowered her eyebrows, looked at the ground, and said: "It's me who is confused, the woman shouldn't talk about state affairs, she just thinks that this should be useful to my father, so ......" said, raised his eyes, and looked at the eldest prince with pitiful eyes, "I don't know much about this crescent moon formation, but the prince of Suguo should be able to find someone to crack it, right?" Please don't blame the master. ”

As the young lady of the famous General's Mansion in the capital before, and the true biography of the He family, she naturally knows how to make herself more beautiful, knows from which angle a man looks at her best, and knows what attitude a man likes most about women. So she first showed her best perspective to the eldest prince, and then showed the feminine side, and grasped the mentality of the eldest prince steadily.

Looking at Yun Luo, who was soft on him, the eldest prince was also a little uncomfortable, but he didn't doubt Yun Luo's words, and said, "It's still the military situation that is the most important." So he took the paper in Yun Luo's hand and asked someone to go and give it to Zhang Moyu.

Yun Luo looked at the paper with important information written on it, and smiled slightly, her back was soaked with cold sweat, and her nerves tensed and she could feel the traces of cold sweat sliding down her cheeks, this smile looked particularly strange on her pale face......

On the other side, Yunyan of Haowangfu naturally knew that something had happened to his cheap father, and he was so anxious that he couldn't do it, and when he saw Nangong Han coming back, he couldn't wait to ask: "Who did the emperor send to support?"

Nangong Han said: "It's the prince of Suguo."

"The prince of Suguo?" Yunyan thought back for a moment and said, "Is it Wenxin's father?"

"That's him." Nangong Han nodded. Yunyan recalled the crescent moon formation of Xichengguo that he had just said in the book, and said, "Won't there be danger?"

Looking up at the gloomy sky, the cloudy sky seemed to be able to collapse at any time, and the sultry weather before the rain also made people breathless, Nangong Han said sullenly: "War, where is there no danger?"

Yun Yan frowned, suddenly walked to the bookshelf, pulled out a map, and said: "The Great Yan Kingdom is in the middle, bordering the Deha provinces of Dongling, Nanqiang, Beihu, Xicheng and Daqi. It is said that there was a great drought for two months last year, and a large number of cattle and sheep died, so they wanted the land of Dayan, which has a fertile soil and a mild climate. Xicheng has a powerful general who is in the limelight in China, called Hu Yanxiao, it is said that he looks more like my Dayan man, is the second son of the former general Hu Yantian, and is also a concubine, but after Hu Yantian died, his brother Hu Yansu did not inherit the title of the mighty general, but Hu Yanxiao, the concubine. He is brave and good at fighting, and is good at using the art of war, which is different from ordinary Xicheng generals. Because it is said that his mother is a female slave of the Great Yan Kingdom who was captured by Huyan Tian! ”

Seeing that Yunyan was suddenly like this, Nangong Han suddenly became interested and said, "What do you want to say?"

"Guess why Xicheng didn't marry Dayan?" Yunyan sat down. "If you marry Dayan, you must sit on the right wife, and their customs are very blood-oriented, and it is impossible to enthrone a prince with foreign blood. It is impossible for us to marry a woman over there, because the chief of Xicheng will not give birth to a daughter, and as long as the princess gives birth to a daughter, the girl will definitely be executed. After speaking, he added: "What is the point of keeping this kind of macho tribe except for harming women?"

The cold light that flashed in her eyes was clearly captured by Nangong Han: "Then what do you think should be done?"

Yunyan now exudes an aura of "I'm going to be mad if I am provoked", and said, "It seems that our Dayan has not established diplomatic relations with the Great Qi State, right?" Have you ever heard of outbred melee attack? ”

"What should I do?" Nangong Han thought for a while, "Dayan and Daqi have no suspicion, and Daqi is only a nomadic country, and the drought is dying, what is the reason for establishing diplomatic relations?" Yunyan opened his mouth coldly and said, "Establish a community with a shared future for mankind!"

"Huh? What is it? ”

Yun Yan explained: "The cavalry of the Great Qi Kingdom is famous all over the world, and if we establish diplomatic relations with them, it will make Xicheng feel a sense of crisis that he is being attacked from the back. Establish diplomatic relations with the Great Qi State, we provide water, they provide necessary help, and the cavalry of the Great Qi State is strong, so they can help the Great Yan get out of trouble. ”

Nangong Han nodded thoughtfully: "This trick is feasible, if Dayan and Daqi establish diplomatic relations, they can't let Xicheng attack Dayan, otherwise they won't have anyone to provide water." That's it...... It's a pity that Yongning ......"

“…… It doesn't have to be forever, right? Isn't there anyone else? Marriages are generally chosen by the daughter of the clan......" Speaking of the back, Yunyan is becoming more and more lacking in confidence. In the royal family, the only unmarried daughters of the right age are Yongning, Xifu and Heni, and Ni is impossible, his father has just set out to go to the west, if he chooses her, it will inevitably cause dissatisfaction among the Hua family, the Xu family and the Suguo Mansion, "The emperor still has an unmarried sister, who is only seventeen this year, serving the queen mother in the palace, is the youngest daughter of the former emperor, and the youngest sister of the current emperor." If not Yongning...... It's this Zhaoyi eldest princess. ”

Listening to Nangong Han's words, Yun Yan said: "Forget it, when I didn't say it, I'll think about what I can do." When Yunyan first saw Yongning, who was the same age as her, she knew that she must be a princess prepared for her relatives, not only her, but also Princess Yonghui. She is also a woman, and she doesn't want another woman to sacrifice herself to save the country.

"Is there any other way for you?" Nangong Han asked, he could only think of this, because there are no eternal friends between countries, only eternal interests. As long as you have the same interests, people will only establish diplomatic relations with you, and harmony will always be a means to consolidate the establishment of diplomatic relations. He wanted her not to have too much burden on her heart, so he spoke out about her.

Yes, but it doesn't work, time waits for no one. Yunyan thought in his heart. She can mobilize all the knowledge in her head to help him train soldiers, and she can also help them make advanced weapons, but there is no time, in case she waits for her to make weapons and then send them to the Great Qi Kingdom, maybe Yunde will already die at the border, and the fastest and most able solution is to marry.

Yunyan felt that he was too useless.
