As soon as he heard that he wanted to be friends with Wei Zhongxian, Sun Chengzong's face became even more ugly.

"You want to get involved with Wei Zhongxian? If you want to be his friend, your reputation will be ruined. ”

On the same front as Wei Zhongxian, he will offend many literati. The literati, with a mouth and a pen, can say that the black is white. Ao Bai didn't intend to argue with Sun Chengzong about this, and said with a wry smile: "If Gonggong Wei appreciates me, treats me as a friend, and asks me to help him come up with ideas, can I refuse?" ”

Sun Chengzong shook his head, he really couldn't refuse, the ministers of the court and the central government were all flattering, and if Ao Bai, who did not have an official position and a half-position, dared to thin Wei Zhongxian's face, he would definitely be unlucky.

"Don't say this in advance, you have talent, Wei Zhongxian also values you, why don't you want to go to Pingliao outside the Guan? Could it be that a body of martial arts is so wasted? ”

This old man always wants to drag me to the battlefield, isn't that harming me? Ao Bai Zhengse said: "I don't want to go to Guanwai, not because I am greedy for life and afraid of death, but because I know that I can't succeed in Pingliao." This problem, I have already discussed with King Xin, the outside must first be inside, I Daming does not have the strength of Pingliao at present, Grandpa Sun, I know that the Guanning Jin defense line was raised by you, but I found that this defense line has a big problem. Would you like to hear about it? ”

Sun Chengzong didn't expect him to evaluate his strategy and said, "If you have anything to say, just say it." ”

Ao Bai slowly paced to the center of the living room and sighed, "If there is no route at Xifengkou. The Guanningjin defense line can indeed block the attack of the Eight Banners Army to a certain extent, but if the other party chooses to take a detour, what is the use of that defense line? ”

History tells people that no matter how strong the defense line is, there will be a day when it will be captured. But there are always exceptions to everything, such as this Guanningjin defense line, because the Jin army can completely bypass without fighting.

Sun Chengzong snorted coldly, "How can it be useless?" If the enemy's army takes a detour, the Ming army can send troops from Ningyuan and Jinzhou to attack Shenyang......"

As he spoke, Sun Chengzong also found a problem, and his confidence was insufficient. The enemy's army made a detour, and the target was the city of Beijing. If the Ming army attacked Shenyang at this time, it would be tantamount to sending troops from both sides. I don't know how many people were left behind by the other party, and the Ming army never attacked the Jurchen city at all. On the other hand, Beijing is in danger, and it can only be detoured to Qinwang.

Ao Bai said lightly: "Encircling Wei to save Zhao is indeed a way, but the problem is that the Ming army has not defeated the Eight Banners Army in the field at all, and can only defend the city, and there are also problems in defense." If the Eight Banners Army chooses to storm the city, it may achieve a victory like the Battle of Ningyuan, but if the other party surrounds Jinzhou and surrounds it but does not fight, Grandpa Sun, what do you think should be done? ”

Sun Chengzong's face became ugly, and the Ming army really couldn't attack it. What the actual situation of Ning Yuan's victory was, he also knew in his heart. He used to be King Xin's teacher, but now Ao Bai overturned his tactics in front of King Xin, making him feel very unable to get off the stage. He thought about it, once the war started, it would be really difficult for Jinzhou to protect itself, and said: "If Jinzhou is besieged, it is necessary to use the troops of Jizhen Sanxie, Xuanfu, and Datong to reinforce it. ”

Ao Bai nodded, and said: "I can only send troops to rescue, and the field battle is not the opponent of the Eight Banners Army, so it is equivalent to falling into the opponent's plan to encircle and send reinforcements." If you don't send someone to rescue, the other party will surround it for a period of time, and the city will run out of food, and if you want to survive, you will only have to surrender and go out of the city desperately. Sticking to Ningyuan is to receive the Han people who fled from Shenyang and Liaoyang, and there is meaning, what is the meaning of Jinzhou's existence? ”

Ao Bai has never been able to think of an answer. When the Eighth Banner Army attacked Jinzhou in the first month, there was not a single soldier in Jinzhou, and the Jin State was not interested, so he set fire to the house and withdrew.

Sun Chengzong sighed: "But if you give up outside the border, it is equivalent to giving up hundreds of miles of land in my Ming Dynasty, how can this work?" ”

Ao Bai looked at Sun Chengzong and said: "Knowing oneself and knowing that the other side will not be defeated in a hundred battles, and to fight, you must first look at the strategic purpose of the other party." There are few Jurchens, less than a million. Even if they break through the Shanhai Pass, how can they rule over tens of millions of Han people in my Ming Dynasty? Their purpose was just to grab something to alleviate the dilemma of running out of food in winter. If they retreat to the pass, leaving only Ning Yuan and Mao Wenlong in Jiangdong Town to echo, what can they grab? ”

Sun Chengzong pondered for a moment and frowned: "You actually agree with Gaodi's strategy of withdrawing from the Guannei. Are you really ready to support the eunuchs? There is no advance or retreat in the art of war, how can we give up the land for no reason. ”

Is there any advance or retreat in the art of war?! Ao Bai was speechless for a while, he had seen a lot of the art of war, but he had never heard of this sentence. If there is no advance or retreat, isn't that looking for death? Sun Chengzong turned out to be like this, and when he became the emperor's teacher, he was obviously a misguided child!

Ao Bai said helplessly: "There is no advance or retreat, very brave and sharp, but what is the benefit?" Obviously he has no strength, and if he insists on fighting outside the border, he will only work for the people and lose money. When necessary, I think Ning Yuan can give up. If the main force and the enemy fight a decisive battle outside the pass, what are the chances of victory? This is tantamount to giving the enemy the opportunity to annihilate the main force of the Ming army. ”

Sun Chengzong's face flushed, but he couldn't refute it. After listening to Aobai's words, he gradually figured out some things.

Ao Bai continued: "Fighting outside the gate, the Eight Banners Army was undefeated in the field. But in the Central Plains, the Ming army occupied the right place at the right time. The Eight Banners Army was not familiar with the terrain of the pass, and as long as they ambushed in the right place, even if they could not win, they could inflict heavy losses on their opponents. It's the same to defend the city, why don't you guard it in the pass? I don't know how much military salary Liaojing will use in a year, and it is certainly not a small amount. If the money for repairing the city is given to the people in the vicinity, and a volunteer army is formed, so that they can farm in peacetime and serve as soldiers in wartime, if the Eight Banners Army really fights in, even if it is defeated, it will not sit still. There are few Jurchens, and once they lose a battle, it will be a devastating blow. As long as you withdraw from the border and only stay in Ningyuan, the opponent will strategically fall into passivity. On the contrary, if you keep spending money to build a city outside the gate. After it is built, it is also the life of being besieged. Even if it is half built, when the other side calls, it will be demolished and burned, and the troops can only retreat. ”

Sun Chengzong sat slumped in his chair and was speechless. He contributed to the Ming Dynasty, and he actually fell into the evaluation of the people and money. But he was also well aware of the combat effectiveness of the Ming army. Once Jinzhou is trapped, I am afraid that the situation that Ao Bai said will happen - encirclement and send reinforcements! If the Ming army can win in the field, where does it need to defend the city, just kill it?

I have insisted on the tactics for so long, but it turned out to be wrong, costing people and money? I am empty as the emperor's teacher, and I am not as good as a commoner boy to see the situation thoroughly, I only think about recovering the land, whether the land is important, or human life is important. If it is said that the purpose of repairing the city is to take the initiative to attack, who of the generals of the Ming army has such courage......

Zhu Youzhen saw that Ao Bai was in high spirits, pointed out the country, and refuted his teacher speechless, and admired it in his heart. No wonder Wei Zhongxian came to look for him, this person is really both civil and military.

Sun Chengzong sighed, his confidence was already insufficient, and asked: "Then what you say, is this battle not going to be fought and retreating to the pass?" ”

Ao Bai smiled and said: "Don't fight for the time being, just use economic sanctions to completely block all trade activities." ”

As early as after the Battle of Sarhu, trade between the two sides ceased to exist. Sun Chengzong smiled bitterly: "We have long stopped trading with the Tartars, is this any use?" ”

Ao Bai said lightly: "On the surface, this is the case, but as far as I know, Shanxi Jin merchants have been trading with the Jurchens in Zhangjiakou, selling them grain, grass and iron. ”

Then he explained some of the general situation, and the three daughters testified for him. Sun Chengzong, He Ruzhong, and Zhu Youzhen were shocked.

Sun Chengzong hurriedly said: "This is a big deal, why didn't you say it earlier?"

Ao Bai said lightly: "I didn't dare to say it casually before. I met with Gonggong Wei today, and I can be sure that Jin Shang is not his person. And he didn't know about it. I have told him that he should invite me to meet again in a few days, and to tell the Emperor to settle the matter as soon as possible. ”

Sun Chengzong sighed: "Do you really think that Wei Zhongxian will do things according to your ideas? You don't know him at all, and he shouldn't be able to see the ministers writing memorabilia, and as soon as you say it verbally, he agrees? Don't be whimsical! ”

"No, I believe in Father-in-law Wei, even if he is not in a thousand ways, he also has a loyal and patriotic heart."

Ao Bai knew very well that these words would reach Wei Zhongxian's ears, and Wei Zhongxian would definitely send someone to find him again. Wei Zhongxian has already begun to find a way out for himself, and winning over Ao Bai is the best way to win over Zhu Youzhen, the king of letters. What's more, he had already told Liang Bin that it would be good for Wei Zhongxian if this matter became something, at least the other party would want to hear what this benefit was.

Today, in front of everyone, he overthrew Sun Chengzong's tactical concept, he was not impulsive, nor did he save money for the Ming Dynasty, but wanted to show himself in front of Zhu Youzhen. As long as Zhu Youzhen can see his ability, there is no reason not to use him in the future.

No one can guess what Ao Bai really thinks. There is still nearly a year to go, and he has enough time to figure out Wei Zhongxian's power, Wei Zhongxian's power is too great, and the Emperor of the Apocalypse will allow him to have such power because of his deep relationship with him, but Zhu Youzhen will not. The more Wei Zhongxian does, the more enemies he will make, and when the time comes, a group of people from the Donglin Party and the Jin Party want his life, will Zhu Youzhen protect him? Even if he survives, he won't be able to keep his current position!

Ao Bai has been observing Zhu Youzhen with his spare eyes, and seeing that there is already a look of worship on his face, this is a good sign. A year later, as long as I do it intentionally, how far can I get along with Zhu Youjian? He and I are both mentors and friends, and he will definitely trust me. When he becomes the emperor and lets Wei Zhongxian step down, I will protect part of Wei Zhongxian's people, this group of people needs a new backstage, and they will definitely be used by me for their vital interests. At that time, it will not take much effort, and there will be a strong force.

It's not that Ao Bai doesn't seek power, doesn't seek wealth, but now the return is too small and can't be seen, and only by putting a long line can you catch a big fish!

If you want to fight, pretend not to fight. The art of war is treacherous.
