Su Fengnuan walked up to him, raised his eyebrows and looked at Xu Yunchu.
Xu Yunchu smiled at Su Fengnuan, and said softly, "I'm not very tired, I can't sleep, so I'll take a walk and see if there's anything I can do to help."
Su Fengnuan smiled and told her about her suggestion that Su Zhen take all the soldiers to dig a ravine outside the four cities and prepare to form a ravine with fire dragons to stop the soldiers and horses of the Northern Zhou Dynasty.
Xu Yunchu praised with a smile, "I also heard about it when I first came out. This is indeed an unexpectedly good strategy."
Su Feng warmly said, "If my predictions are correct, Chu Han will investigate when I go back tonight. I won't attack the city tomorrow, but if I attack the city tomorrow night, I will rush to work day and night. The Gully Fire Dragon will come in handy when it is finished. "
Xu Yunchu nodded, "If all 70,000 soldiers and horses are used, it's about the same."
Su Fengnuan looked at the incineration site, smiled and said, "From the day when the soldiers and horses of the Northern Zhou Dynasty invaded Yanbei, there were only 50,000 guards in the Yanbei Palace. Before I came to Yanbei, there were only less than 5,000 guards left." , Lost 45,000. Tonight, the Northern Zhou Dynasty attacked the city. I tried every means, but I still lost 2,000 guards. Now there are only 3,000 people left in the Yanbei Guards. And the 30,000 people I brought Lu soldiers and horses also lost more than 10,000 tonight. Now you have brought the emperor's 50,000 Imperial Forest Army, and all the soldiers and horses in the city add up to 70,000, which is not enough to compete head-on with the hundreds of thousands of Northern Zhou troops. So I Thinking about using this method, it would be best to stop the Northern Zhou soldiers from attacking the city again without spending a single soldier. Otherwise, I am afraid that even if we hold out until the Western Region soldiers arrive, there will be very few of these people left."
Xu Yunchu also looked at the incineration site, where the flames were soaring into the sky, it had been burning for more than an hour, and it was still going on. He nodded, but also put away his smile, and said in a deep voice, "You're right. Once the ravine fire dragon is ignited, it will surely stop the Northern Zhou soldiers from approaching the gate of the west city. If they can't get close, they won't be able to attack the city." Paused , and said, "However, water can extinguish fire. If Northern Zhou used water to extinguish it..."
Su Fengnuan said, "Yanbei's climate is cold and hard, so the moat had already dried up decades ago. The nearest water sources to Yanbei City are Heishui River and Qingshuitan, but the nearest sources are also dozens of miles away. The water diversion in the city is connected to Qingquanling, a hundred miles away, with iron pipes, but it is buried more than ten feet underground. Since they cannot enter the city, they naturally cannot receive the water source in the city. Therefore, when Chu Han came to attack Yanbei, he sent The camp in the rear was set up thirty miles away, because it was close to Qingshuitan. The soldiers of the Northern Zhou Dynasty used the water from Qingshuitan to divert water."
Xu Yunchu suddenly said, "In this way, Chu Han can't bring water to put out the fire."
Su Fengnuan nodded, "Even if he wants to divert water to put out the fire, it will take a lot of time. What we want now is to delay the time and wait for the reinforcements from the western border."
Xu Yunchu nodded, and suddenly asked, "Is it possible that we go to Qingshuitan to poison? Since the soldiers and horses of the Northern Zhou Dynasty diverted water to Qingshuitan, once they are all poisoned..."
Su Fengnuan sighed, "I've thought about this too, but the water in Qingshuitan leads directly to Qingquan Ridge, poisoning Qingshuitan, unless we don't drink the water in Qingshuitan, we will hurt one thousand enemies and eight hundred ourselves. " After finishing speaking, he said again, "All the people in Yanbei use water from Qingquanling. Once they poison Qingshuitan, it will not only harm the Northern Zhou army and Yanbei City, but also the people in the entire Yanbei territory. "
Xu Yunchu immediately stopped thinking and said, "It's really not advisable, so let's not think about it."
Su Fengnuan smiled, looked at the northern sky, and sighed, "Even if it is desirable, it is not desirable. The two countries were at war, although the Northern Zhou Dynasty was unrighteous, and the wolf was ambitious and invaded the Southern Qi. Earlier, I rescued Yanbei City in Fengkou Mountain. , ignited a forest fire, and burned 90,000 soldiers and horses in Chu Han. Although it was the Northern Zhou Dynasty's own fault, it was really a sin to be a living creature."
Xu Yunchu heard the words, "Young lady has a benevolent heart."
Su Fengnuan sneered, shook her head, looked at him and said, "If I had a benevolent heart, I wouldn't set fire to the mountains and burn Chuhan's 90,000 soldiers and horses. However, poisoning can be serious or serious. For example, the military doctors can easily cure it, but the poisonous medicine will kill people. If the hundreds of thousands of troops in the Northern Zhou Dynasty were poisoned to death, if there are gods and Buddhas in the world, I am afraid it should not be done."
Xu Yunchu laughed, "I remember the girl said earlier that she doesn't believe in Buddhism."
Su Fengnuan sneered, "I don't believe in Buddhism, but imagine that if hundreds of thousands of Northern Zhou troops were poisoned to death, if it was not handled properly, the people of Yanbei would also suffer from water diversion, and even, it might cause a plague. Once the plague If it spreads, then the whole of Yanbei will be over. We are here to save Yanbei, not to fight for war, not to kill all the soldiers and horses of Northern Zhou. The goal is to save the people of Yanbei and let Northern Zhou retreat. "
Xu Yunchu said with shame when he heard the words, "Yunchu is not talented and narrow-minded. What the girl said is very true."
Su Fengnuan smiled and shook his head, "Uncle Xiaoguo is self-effacing. You are not narrow-minded. Under the pressure of the situation, you can think of some special methods, and you are not outside the frame. In front of family and country affairs, you don't talk about your heart." After the words fell, She smiled, "It's just that I have already burned Chu Han's 90,000 troops. This kind of crime is not because of helplessness, but there is a little other way, and I don't want to burn people."
Xu Yunchu also smiled, and said, "Northern Zhou is coming in a menacing manner, vowing to destroy Yanbei City, even if we have the heart of heaven and good life, I am afraid that Northern Zhou will not think so, and will not retreat easily."
Su Fengnuan said, "For many years in the Northern Zhou Dynasty, the country was rich and the army was strong, and we were not afraid of war, but our Southern Qi is now suffering from internal and external troubles. After a long time, the supply of food, grass, and military equipment will be insufficient. Slap Chu Han hard, and then tell him to retreat and go back to Northern Zhou."
Xu Yunchu nodded, "Indeed, we in Southern Qi are afraid of war now." After saying that, he said, "But Chu Han, the prince of Northern Zhou Dynasty, is an ambitious person. If he doesn't teach him a lesson, he will return to Northern Zhou. Repeat."
Su Fengnuan tapped his head, and said softly, "When I was in the western region, I seriously injured him, but I couldn't kill him. It was because of a piece of cold jade pendant. The day before yesterday, I was on the bank of the Black Water River. I had a chance to kill him. But because my cousin Su Sixuan was in his hands, I was threatened by him, but I couldn't kill him. It's not easy to find a third chance now."
Xu Yunchu said, "Among the princes of the Northern Zhou Dynasty, the second prince is the only one who favors the second prince. The other princes are not as ambitious and capable as the second prince. Therefore, they are not as favored as the second prince. But the other princes have been suppressed by him for a long time. There is also a lot of dissatisfaction. If we find a way to cause civil strife in the Northern Zhou Dynasty and the royal family and princes fight, maybe the Northern Zhou Dynasty will have no time to raise troops to invade the Southern Qi Dynasty.
Su Fengnuan smiled and said, "That's a good idea. When the soldiers from the western border come, we will fight a fierce battle. After Chu Han retreats, we will find a way to make them fight among themselves. After Chu Han was defeated, Countless soldiers were killed and wounded, even if the King of Northern Zhou loves him, he will be somewhat dissatisfied, if something else happens to him, all the princes will deal with him unanimously, he will feel better."
Xu Yunchu nodded with a smile, "Exactly."
While the two were talking, Su Zhen walked over from Qian Street, saw the two of them, and immediately said, "I will arrange soldiers to dig the ditch in turn, one group rests, and the other group digs. This way, the effect will be higher." Luo Luo said to the two of them, "Go back and rest, especially Uncle Xiaoguo, you have traveled all the way from the capital, and you haven't had a good rest, have you? I'm watching in the city, you go."
Xu Yunchu said with a smile, "I couldn't sleep at first, so I went out for a walk. Now that Miss Su has thought of a countermeasure, I can take a solid rest."
Su Zhen stepped forward and patted Xu Yunchu on the shoulder, "Go! Wait for the soldiers and horses from the western region to drive Bei Zhou back, and then we'll drink."
Xu Yunchu agreed with a smile.
Although Su Fengnuan wasn't too tired, Su Zhen insisted on letting her go back and rest, so she stopped shuffling and went back to Yanbei Palace.
When she returned to her courtyard in Yanbei Prince's Mansion, she saw Su Sixuan waiting in the courtyard. She was sitting on a rattan chair, holding a branch in her hand, paddling on the ground. She raised her eyebrows slightly and asked , "It's so late, why haven't you rested yet? What are you doing here?"
Su Sixuan raised her head when she heard the sound, threw the branches in the water, immediately got off the wicker chair, and quickly walked towards Su Fengnuan, "Sister, are you back?"
Su Fengnuan nodded, looked at her, and saw that she had obviously washed up, much cleaner and tidier than at night.
Su Sixuan came closer, looked at Su Fengnuan, and whispered, "Sister, can I ask you something? If I don't ask, I won't be able to sleep..."
Su Fengnuan looked at her and saw that she was a bit embarrassed, so she raised her eyebrows and pointed at her, "Are you asking about Uncle Xiaoguo?"
Su Sixuan was startled and looked at her with wide eyes, "How do you know?"
Su Fengnuan smiled, went to the rattan chair and sat down casually, and said casually, "What do you want to ask him? Does he have someone he likes? Or is there a marriage? Or is there any woman who likes him? ? Or how is his family background? Who is there in the family? How is his character? Is he good or not?"
Su Sixuan opened her eyes even wider, looking at Su Fengnuan, she seemed to be frightened for a moment, and was dumbfounded.
