Looking at the backs of Cao Yun and his group leaving, Yang Zhi asked in a low voice: "Your Majesty, do you really need the cement formula and construction technology to exchange for those people back?"

"Of course." Qin Feng nodded: "This thing is not a big deal."

"But if the Qi people own this thing, they will create more solid fortresses, which will cause a lot of trouble to our future battles." Yang Zhi frowned and said, "Although the Qi people may also figure out how to make it themselves, they will be able to apply it a few years later. Your Majesty, this is not a small matter. We have tried the city wall with reinforced concrete structures to resist strikes. The catapult has little effect on him. A city wall is basically a whole. Even our thunder fire has no obvious effect. Unless it is a super large catapult, that thing is really not a good thing."

"A tenacious city is never resisted by a strong wall. Have you forgotten the Eagle-billed Rock? Is it steep enough, and it is still conquered? In my heart, those 185 captured soldiers are much more expensive than these things. Mr. He, do you think I should change it?"

"Of course it should be replaced!" He Rentu smiled and said, "I don't understand the country's major policies, but I know that since those people have been through life and death for the sake of the Ming Dynasty, the Ming Dynasty should naturally give them the respect they deserve. The hearts of people are much more valuable than the city walls. Moreover, Murong Hai is a well-known figure among the barbarians. If you exchange such people, it will be beneficial for us to further win over the hearts of the barbarians."

Qin Feng nodded and walked down: "I can't let my soldiers bleed and cry, and the Ming Dynasty will not give up any of his people."

"Your Majesty is right, Yang Zhi has received the teachings." Yang Zhi nodded.

He Rentu smiled and said, "Your Majesty's plan is so wonderful that it is so easy to use, and a thorn was planted in the hearts of Tuobayan and Cao Yun. Tuobayan is in a highly tense and sensitive period at this time. If this needle continues, he will be worried about gains and losses."

"Just give out the anger!" Qin Feng said: "If Cao Yun is so easy to be fooled, then he will not be Cao Yun."

"Your Majesty, I'm wondering, if Cao Yun promised to exchange Tuobayan's head with us today, what should we do? It's obvious that we can't give them iron smelting technology." He Rentu asked.

Qin Feng laughed: "If Cao Yun was really willing to exchange Tuobayan's head, I would really exchange it for him."

"Are we suffering a great loss? Even if a Tuobayan is betrayed, how much is it?" He Rentu said in surprise.

"Is it a problem for Tuobayan alone?" Qin Feng sneered: "It was Cao Yun who knew the powerful relationship here that he refused without thinking about it."

"It turns out that His Majesty had known that Cao Yun could not agree to it before saying that. At that time, the last general was shocked." Yang Zhi smiled.

Qin Feng smiled calmly and said to Yang Zhi: "After going back, prepare well. When Murong Hai and the others come back, we will welcome them home with a grand ceremony. Should you, the general, know how to use this ceremony to make our soldiers' morale more high?"

"Of course. Your Majesty, I want to transfer Zhou Jiyun's troops stationed in Kunling County to a cavalry battalion, and then transfer Huang Gang's troops, who had just been reorganized, so that they can feel the kindness of our Emperor's love for the soldiers." Yang Zhi said: "These two battalions are cavalry battalions, and they will be able to arrive here soon."

"This is a good idea." Qin Feng smiled and said: "They shortly after they surrendered, so they should let them feel the difference between our Ming Dynasty and other countries."

On the east side of the Lotus Peak, Cao Yun led Tuobayan and Bian Wenzhong to a platform in the middle of the road. Tuobayan finally couldn't help but bow deeply to Cao Yun: "Thank you for your attention. Tuobayan had no choice but to bow and serve Da Qi, even if he was wrapped in a horse and a corpse."

Cao Yun smiled coldly, "Do you think the condition proposed by Qin Feng today is taken seriously?"

Tuobayan was stunned.

Cao Yun turned around and looked at Bian Wenzhong: "Bian Wenzhong, tell me if Qin Feng really wanted to replace Tuobayan's head with their iron and steel smelting technology with us, should we change it?"

Bian Wenzhong hesitated for a moment: "Your Majesty, you will not dare to say anything at all in this matter. It is just that the skills of smelting iron and steel making are the core secrets of the Ming Dynasty. The crossbow machines, thunder fire and other weapons they own are all developed on this basis. Now they have added the power system of their navy. We can all make these things, but the problem is that the steel technology does not meet the requirements, and the things made will be damaged in a few days. It is purely thankless. If we can master such skills, our Daqi's combat power will step into a stage. In the confrontation with the Ming people, the Ming people's military advantages will disappear. For us Daqi, it is naturally a great advantage."

Cao Yun smiled: "Yes, because of this, I know that Qin Feng just wanted to allocate the relationship between our monarch and ministers, and give us a big discount on our trust. This kid is very vicious! The core technology can never be obtained from the enemy. The only way is to develop it yourself."

Tuobayan and Bian Wenzhong both nodded at the same time.

"My skilled craftsmen in Daqi don't know about Fanfan. In the past, the court did not pay attention to them, but only knew how to enslave them and exploit them. Now it's different. Of course, we can give what the Ming people can give to the craftsmen, and we can also give to them. Hahaha, that's what Qin Feng said to me. It's really touching. During the trip to the Ming Dynasty, Qin Feng's casual words were Feng Guibao. On the contrary, I was too lazy to pay attention to what he said to me solemnly and seriously." Cao Yun smiled. "Maybe it will take a long time, but I can wait."

"Your Majesty is wise."

"Tuobayan, Qin Feng made this request in front of you today. Do you know what it is for?"

"For the relationship between the minister and His Majesty."

"You only understand the superficial things. Now I tell you something deeper. Why didn't he say that he used this to exchange for Guo Xiancheng's head? Or to exchange for Cao Hui's head? Because he knew that this was impossible. And you, obviously still cannot reach the height of these two people, may succeed and may be alienated. Do you know? For a moment, I was really moved." Cao Yun looked at Tuobayan, "Now do you know what to do in the future, right?"

Tuobayan took a deep breath: "Your Majesty, Mo will understand. Mo will work hard to reach the height of General Guo and others, and make himself a person who cannot be replaced and an indispensable person for Da Qi."

Cao Yun laughed: "Okay, you really have insights. Tuobayan. Only when you reach this level can you be the one who will not be betrayed under any circumstances. Otherwise, if there is enough profit, a person who is not important enough may be betrayed at any time."

At the foot of Lianhua Mountain, the two armies were still facing each other. Whether it was Guo Xiancheng, who was commanding the army in Qi's ** formation or Zhou Jiyun, who was commanding the army on the Ming army, they were all nervously and uneasy at Lianhua Peak. These two former comrades-in-arms now belong to two camps. It was not until they saw that Cao Yun and Qin Feng were safe and sound and went down the mountain peacefully along different roads that both sides breathed a sigh of relief.

As the two returned to the camp, the two armies turned around and slowly retreated to the rear.

"Qiaoshou, I am ready to hand over the cement formula and related construction techniques to Qi people." Qin Feng ordered Qishou.

"What?" Jieshou was shocked, and Zhou Jiyun on the side was also stunned. "Your Majesty, what happened? How could he give such an important thing to the people of Qi?"

"How important can it be? I'm afraid that the Qi people will find out this thing." Qin Feng smiled and said, "I want to exchange these things for Murong Hai and the others' back. The lives of the 185 Ming Dynasty children are worth this price."

He was very slow to speak, obviously he was not happy.

"Let the long-term vision." Qin Feng reached out and knocked on his head, "The Qi people owned this thing, not only could they build solid city walls, but they would also build spacious and solid roads. When we fight in the future, wouldn't the army be more easy? Our military equipment really takes their messy roads now, how far can we go in a day? Don't you see what the roads in the six eastern counties are now? What are the roads in the four counties in Jiangnan? The merchants who contracted logistics complained and had already gone to the Ministry of Revenue and the Ministry of War to cry, and they wanted to increase the money!"

"Your Majesty, you can always find reasons that people cannot refuse." The clever hand said dissatisfiedly: "Well, the lives of one hundred and eighty-five people are worth the price! It's a thousand gold bar!"

In Qi** Camp, Tuobayan took a jar of wine and went to the remote prisoner camp again. Compared to the last time he came, the wounded soldiers here were in much better condition, at least the wounded parts on their bodies had been bandaged.

He sat on the edge of Murong Hai's cage, poured a bowl of wine, and handed it over silently.

"Although we are enemies now, I still have to thank you. The doctor has come to see the brothers, put medicine, and bandage them. Although it is very casual, we are all desperate and I think we can survive it." Murong Hai raised the wine bowl and smiled. "Why, you look very unhappy?"

Tuobayan was silent for a moment: "You are going back, and the Emperor of Ming Dynasty exchanged all 185 people here with cement formula and construction technology."

Murong Hai was surprised and said for a long time: "How can we be worth such a high price for a life of a cheap person?"

"It's enough for Emperor Ming." Murong Yan said: "The two sides agreed that they would exchange in a day. Congratulations, Haizi, you will be reunited with your family soon."

Murong Hai was silent for a while and suddenly burst into laughter: "Tuobayan, I said you chose the wrong choice? Look, look, a guy like me who is completely useless, His Majesty is willing to exchange me for a large price. If it is the Emperor of Qi, is it possible? Hahaha, I said, you will regret it in the future."

Tuobayan stood up and slapped a jar of wine in front of Murong Hai: "I will let the Emperor of Qi realize my irreplaceability and will not sell me under any circumstances. Haizi, after this farewell, I hope we will never see you again."
