Xue Ju, the overlord of Western Qin, led an army of 100,000 troops into Pingliang County, crossed the Danzheng Gorge and entered Anding County, he ordered Liang Shidu to lead an army of 10,000 to defend Anding City, and he personally led an army of 90,000 troops to garrison Shallow Water Plain, eyeing Guanzhong, at this time it was less than ten days before Li Yuan captured Guanzhong, Xue Ju's army pressed north, which shook Guanzhong.

Li Yuan had just lost his adviser Liu Wenjing, and was upset, so he received the news that Xue Ju's army was pressing, and he was anxious about internal and external troubles, so he urgently ordered Qu Tutong to be the vanguard, and led an army of 20,000 troops to garrison Xinping County, defending the Western Qin army in a hurry, and ordered Li Xiaogong to be the main general, Liu Hongji as the deputy general, and led an army of 80,000 people to Beidi County to meet the battle.

Li Yuan's Tang Palace, the Great Prime Minister's Mansion was set up in the Wude Hall of Taiji Palace, the Wude Hall is the place where Yang Jian announced the abolition of the crown prince Yang Yong, and it is an important palace of the Great Sui Imperial Court, it is actually composed of a group of buildings, the front hall, the apse, the left and right side halls, and hundreds of halls and pavilions such as the Left Panlong Pavilion and the Right Qi Feng Pavilion.

Li Yuan's office is called Tang Wang Pavilion, which was changed from the library in the Wude Palace, and the back is still the place where the books are stored, and the front has become his office room.

At this moment, Li Yuan was pacing back and forth in the room with his hands behind his back, his eyes couldn't hide the look of worry, the kind of high-spirited spirit when he just captured Guanzhong was already gone in his heart at this time, he captured Guanzhong only ten days, and the crisis followed, Yang Yuanqing led the army into Guanzhong, making him lose face, and then kidnapped the military advisor Liu Wenjing, so that he was full of anger and had nowhere to vent, but before he could take a breath, the army of Western Qin Xue Ju swept and killed, and wave after wave of crises made him breathless.

He can basically determine that Xue Ju's attack on Guanzhong must be related to Yang Yuanqing, otherwise Yang Yuanqing would not have withdrawn in such a timely manner, and gave Danzheng Gorge to Xue Ju, so that the Western Qin army could drive straight in, and some kind of compromise must have been reached between the two of them, perhaps Xue Ju took Guanzhong, and Yang Yuanqing got Guannei.

The resentment and depression in his heart almost made Li Yuan can't help but look up to the sky and howl, at this time, Li Jiancheng's voice sounded at the door, "Father, can the child come in?" ”

Li Yuan held his breath back in his heart again, "Come in!" ”

Li Jiancheng walked in quickly, bowed and saluted, "Father, the child has something to report." ”

Li Yuan saw that his eldest son was not wearing an official uniform, only wearing a cyan robe and a flat scarf on his head, he was a little unhappy and said: "You are the prince of Tang Shizi, and you are also the secretary of the household department, and you are in a high position, how can you wear the color of cheap clothes, it is unseemly." ”

Li Jiancheng hurriedly said: "There is a reason why the child is dressed like this, and my father listened to me." ”

"Say it! What's up? ”

"The child just got the information, Yang Yuanqing's army has quickly moved north, and it has not cooperated with Xue Ju to attack Guanzhong, so in this battle, we are actually only facing Xue Ju."

Li Yuan was overjoyed and asked anxiously: "Can you be sure that Yang Yuanqing's army is not there?" ”

Li Jiancheng nodded affirmatively, "The child can be sure, it's indeed not there!" ”

Li Yuan patted his forehead with joy, this is simply great, without Yang Yuanqing's army, most of the stones in his heart would be removed, and he could finally sleep next to the table tonight.

Li Jiancheng saw that his father was ecstatic, and his heart was also full of a sense of accomplishment, but he had something else to do to find his father, and he said: "Father, the child came today to have a strategy to retreat from the enemy, or rather, there is a way to deal with Xue Ju." ”

Li Yuan has always trusted his eldest son, for many years, Li Jiancheng has been his right and left hand, he knows that Jiancheng is very cautious and will not express his opinions easily, if he wants to say, it must be confident, Li Yuan perked up and said with a smile: "You say, what way?" ”

"The child suggested the implementation of the strategy of long-distance friendship and close attack, Yang Yuanqing is estimated to be allied with Xue Ju, then we can also form an alliance with Li Rail, the king of Xiliang, after all, everyone is the Li clan, and more importantly, Li Rail is deeply threatened by Xue Ju, and the two are incompatible, we can unite with Li Rail to deal with Xue Ju together, so that Xue Ju will suffer from the enemy on his back, and it will be difficult for him to last."

"What about Yang Yuanqing's influence, have you considered it?"

Li Jiancheng smiled slightly, took out a text message from his arms, and handed it to his father, "This is the information that Han Chang of Fengzhou just sent someone, and after reading this information, my father will understand the truth about Yang Yuanqing." ”

Li Yuan took the letter and read it, with a look of shock in his eyes, Yang Yuanqing's Fengzhou army lost more than 80,000 people, he always thought that it was about 50,000 people, but more than 80,000 people, this Fengzhou defensive battle was really tragic, no wonder the Turkic army lost 200,000 people.

Han Chang is Li Jiancheng's subordinate, and he is a spy he personally selected to go undercover in Fengzhou, he trusts Han Chang very much, and Han Chang's intelligence makes him convinced.

Li Jiancheng said with a smile: "The child has always thought that this time Yang Yuanqing's attack on Guanzhong was a complete bluff, it should be that he defeated the Turkic army, and the losses were extremely heavy, he was afraid that we would attack Fengzhou, so he rushed to attack us first, this time his hurried retreat, it can be seen that he is very timid, but the child has no evidence, so he does not dare to say anything, and now there is Han Chang's intelligence, which confirms that the child's guess is completely correct." ”

Li Yuan breathed a long sigh of relief, if this is the case, then there will be no worries about the battle between him and Xue Ju, and the completed strategy of long-distance and close attack will also be possible, so he nodded and said: "Actually, the first thing I plan to do is to attack Li Rail, I want the horse farm in Hexi, and the war horse is extremely important to us, but now dealing with Xue Ju is my first priority, and I agree to form an alliance with Li Rail." ”

Li Yuan glanced at Li Jiancheng's dress, and suddenly woke up, "Jiancheng, do you want to go in person?" ”

Li Jiancheng nodded, "To form an alliance with Li Rail, it must be a child." ”

"No way!"

Li Yuan flatly refused, "Liu Wenjing was kidnapped by Yang Yuanqing, which makes me regret it to this day, I can't let the tragic thing happen again, you are Tang Shizi, you must not go." ”

"Father, Li Liang is not Yang Yuanqing, this person does not have this kind of courage and courage, he does not dare to detain the child."

Li Yuan sighed and said: "I know that Li Rail is just a dog guarding the household, he really doesn't have the courage to detain you, but what I'm worried about is Yang Yuanqing, once he and Li Rail reach some kind of deal, I'm afraid that Li Rail will hand you over to Yang Yuanqing, or his subordinates will hand you over to Yang Yuanqing, then I will regret it too late, hey!" It's better to let your second uncle go, he can represent me, and he also knows Li Rail, and can persuade Li Rail to form an alliance with us. ”

Li Jiancheng sighed secretly in his heart, although he thought he was the most suitable, he had to admit that his father's thoughts were more detailed, and Li Jiancheng no longer insisted.

At this time, he thought of another thing, and said: "Father, there is also the second brother, I suggest that the second brother should lead the army to deal with Xue Ju, Xiaogong is probably not Xue Ju's opponent." ”

Li Yuan was still angry because of Li Shimin's shooting of Li Zhiyun, and deprived Li Shimin of the right to lead troops, Li Jiancheng's suggestion made him hesitate, he pondered for a long time, but still shook his head, "I won't think about it for the time being, let's talk about it later!" ”

．．．．．．．．．

Although Li Shimin was deprived of the right to lead troops, he was not imprisoned, he still served as Jing Zhaoyin, and was also named the Duke of Qin by his father Li Yuan, he had no complaints, he was busy in the capital every day, inspecting public security, stabilizing grain prices, repairing the walls, and stabilizing prices, these are all things about Jing Zhaoyin.

However, Xue Ju's large-scale invasion also made Li Shimin worried, he heard his master Sun Sheng say that Xue Ju was the personal guard of the King of Qi, strong in martial arts, insidious and cunning, not reckless, Li Shimin was very worried that Li Xiaogong would be defeated lightly.

But there was no way to worry about it, his father seized his military power, making it impossible for him to lead the troops to battle, and Li Shimin could only suppress his worries in his heart.

Early in the morning, after reading several reports, Li Shimin was ready to go on patrol on the streets as usual, and as soon as he walked out of the palace, he saw a scribe talking to his soldiers, this scribe was about 30 years old, dressed in cloth clothes, his face was as white as jade, he had three black beards, and his eyes were clear.

"What's the matter?" Li Shimin asked.

"Back to Duke Qin, this gentleman said that he would come to take refuge in you, and he was willing to serve you."

Li Shimin was stunned for a moment, he looked at the scribe, and then bowed and smiled: "In Xia Shimin, may I ask your surname?" ”

The scribe stepped forward and bowed and said: "In the next surname Fang Qiao, the word Xuanling, a native of Licheng, I have heard the name of Qin Gongying for a long time, and I have come to take refuge." ”

'Fang Xuanling! ’

Li Shimin pondered for a while, and asked with a smile: "I have long heard that the imperial history of Licheng Fang is the most honest official in the world, but the brother is the same clan?" ”

Li Shimin said that Fang Yanqian, who was praised by Emperor Wen of Sui as the first honest minister in the world, Fang Xuanling smiled slightly: "It is my father!" ”

Father Lian will produce a virtuous son, Li Shimin said happily: "Please come into my official room for a while." ”

Fang Xuanling wants to come to him, Li Shimin always has to test him to learn, he can't accept him because his father is a Qing official, Fang Xuanling also knows, and he doesn't shirk, and sits down with Li Shimin.

Fang Xuanling sat down and said with a smile: "Duke Qin is worried about Xue Ju's matter? ”

Li Shimin did not deny it, and said calmly: "Exactly! ”

Fang Xuanling smiled slightly: "But for me, if you want to break Xue Ju like a palm view, you can make him retreat with a little trick." ”

Li Shimin was overjoyed and hurriedly said, "Sir, please advise!" ”

"It's very simple, use the strategy of encircling Wei to save Zhao, Xue Ju built the capital in Shangtai County, Tianshui County, his total strength is only 130,000, and he has to defend all parts of Hehuang, and now he actually poured 100,000 troops to attack the fortifications, then his capital must be empty, but he can order an army to kill Shangtai County with great fanfare, Xue Ju is worried that the old nest will be lost, and he will inevitably withdraw in a hurry, so the danger in Guanzhong can be solved."

Li Shimin nodded slowly, although the strategy is simple, if you don't understand the details of Xue Ju, you don't dare to use this plan lightly, it seems that this Fang Xuanling is a person with a heart, and he has been paying attention to Xue Ju for a long time.

"Brother Fang's strategy is very good, so I will report it to my father and suggest it."

Fang Xuanling shook his head, "With all due respect, I think the real crisis of Tang Gong is not Xue Ju, but Taiyuan." ”
