Li Jiancheng settled down a little in his heart, as long as he didn't mention Concubine Yin De, he could deal with it calmly, and it was a big deal to let Gao Biaoren take the final responsibility.

"Father, how could the sons not know the consequences of the land annexation, when Yin Guiping came to ask the sons for help, the sons felt that it was inappropriate, but because of the face of the emperor's relatives and relatives, they reluctantly agreed, and later the sons told Gao Biaoren that this matter should be properly resolved, it can be a fair trade, or it can be replaced by land, in short, it cannot damage the interests of homesteaders, and at that time it was just said that there were ten hectares of land, and how did it become dozens of hectares of land in the end, and it was actually ten dollars per acre of land, what is hidden in this, the sons really don't know, Please Father, Emperor Mingjian! ”

Li Jiancheng said it very sincerely, and what he said was completely true, he really didn't know that there would be such serious consequences, if he knew, he would never agree.

Li Yuan has also served as a magistrate for a long time, and he will be very angry with this kind of officialdom of 'those who are good at the top, but they will be very bad at the bottom', and he knows that Jiancheng is telling the truth.

What's more important is that Jiancheng has been with him for many years, and he knows his eldest son very well, and Jiancheng, who has always been lenient to the people, will never allow ten hangings to buy an acre of land, which must be caused by Gao Biaoren's intentions and indiscriminate behavior.

However, Li Yuan's anger did not subside, and he said coldly: "I must investigate this matter to the end, in my Tang Dynasty, the annexation of land will never be allowed, and the people involved will not be tolerated!" ”

Li Yuan used two 'never!' in a row. Li Jiancheng deeply felt his father's dissatisfaction with him, and he sighed secretly in his heart and lowered his head......

In the room, Li Shimin stood in front of the window with his hands in his hands, staring at a few dead trees outside the window, but he was listening carefully to Pei Lian's narration in his ears, and he would not let go of every detail.

At this time, his heart was full of pride, and a small land annexation case beat the prince to the ground, and made him taste the sweetness of victory.

But Li Shimin also knew very well in his heart that the prince and Concubine Yin De did not have a special relationship. In the end, his father would not depose the crown prince because of this matter, at most, it would affect the prince's status in his father's heart, but even if it was, it was a result that he was very happy to see.

However, Li Shimin carefully designed this case in order to persuade his father to send troops to the Sui Dynasty. The Sui Dynasty and the Turks went to war in the north. Yang Yuanqing has already shrunk the defensive line for this reason, this kind of golden opportunity, if the Tang Dynasty does not seize it, I am afraid that there will really be no chance in the future.

Now the crown prince is involved in the Chengdu land annexation case. He has lost his influence in front of his father, and at this time he must seize the opportunity to persuade his father to send troops.

Thinking of this, Li Shimin turned to Pei Lin and said: "The land annexation case will be investigated in accordance with the normal regulations, if there is, if there is not, there will be none." This kind of thing can't be hidden from the emperor, and there is no need to add oil and vinegar, so as not to be self-defeating. ”

Pei Lin hurriedly agreed: "The lowly position understands, the lowly position will order the imperial Shitai to do what His Highness wants." ”

"Alright! This matter will be hard for you, I will enter the palace immediately and persuade my father to send troops. ”……

After Li Shimin explained Pei Lian, he hurried into the palace, and he came to Wudedian Square. Standing on the steps waiting for the summons, he was thinking about how to convince his father.

After a while, a eunuch hurriedly came and bowed, "The Holy Lord has summoned His Highness." Your Highness, please come with me. ”

Li Shimin tidied up his clothes, walked up the steps quickly, and followed the eunuch to his father's imperial study.

He waited outside the imperial study for a while, and a eunuch came out and whispered, "Your Highness, please come in!" ”

Li Shimin walked into the room. found that Xiao Yu was also there, and he nodded to Xiao Yu. Then he knelt down on his knees and kowtowed to Li Yuan respectfully, "My son asks my father for peace!" ”

Li Yuan was not in a very good mood because of the prince's affairs, although he knew that the prince would not do anything to harm the people, but the prince was indeed involved in this Chengdu land annexation case, which made him a little disappointed in the prince.

However, Li Yuan also knew that Pei Lin and the prince had a holiday, and it was probably unfair to let Pei Lin investigate this matter, and Chen Shuda, Dou Liang and others were the prince's party, and they would even favor the prince, so this matter could only be held responsible by a neutral person, Xiao Yu was honest and fair, and he was the person he trusted the most.

Li Yuan waved his hand, "The emperor is flat!" ”

"Thank you, Father!"

Li Shimin stood up, Li Yuan glanced at him, and a smile barely appeared on his face, "Does the emperor have anything to do with me?" ”

"Erchen received urgent information from Tang Feng, Yang Yuanqing has personally led an army of 80,000 to Shanyang County, father, this is an opportunity."

"Opportunity?"

Li Yuan looked at him meaningfully, "You want to persuade me to send troops to the Sui Dynasty, is that so?" ”

Li Shimin sighed deeply in his heart, he could feel a trace of hesitation from his father's tone, he knew that his father was still a little indecisive, to put it bluntly, he was afraid of the revenge of the Sui Dynasty, and it had nothing to do with the righteousness that the prince said.

"Does my father think that the Sui and Tang dynasties can really coexist for a long time?"

Li Shimin tactfully persuaded his father, "It's not that the Sui Dynasty doesn't want to destroy us, it's because they don't have this strength for the time being, if there is no Turkic invasion, Erchen dares to assert that Yang Yuanqing will definitely attack Guanzhong in the spring of next year, because he has already tested our reality in the battle of Huining County, and it is not because we are righteous, and not because we are afraid of him, he will let us go, Yang Yuanqing does not have this kind of woman's benevolence, he grabbed a large amount of materials from Goryeo, so that he has the confidence and financial resources, he cleaned the officialdom of Hebei, No one dared to oppose his decision, Father Emperor, the time was ripe for the Sui army to attack Guanzhong. ”

At this time, Xiao Yu next to him said: "The minister agrees with the words of His Royal Highness King Qin, Yang Yuanqing is indeed very likely to prepare to attack the Tang Dynasty in the spring of next year." ”

Li Yuan's brows furrowed slightly, "Why did Aiqing say this?" ”

Xiao Yu smiled slightly, "In fact, it can be judged from some clues, such as his preparation to issue silver coins, which is obviously aimed at the Tang Dynasty, first use silver coins to disturb the prices in Guanzhong, so that the prices skyrocket, and the people's grievances are boiling, and then he took the opportunity to send troops to attack, which is his usual trick, and for example, since October last year, his army has been actively preparing for Hebei and conducting intensive training, and in October this year, the Sui army has begun to prepare for war again, and it has also carried out intensive training, which is almost exactly the same as last year."

Another point, he could easily destroy Dou Jiande, but he didn't make a move, obviously he wanted to leave a relaxation zone between Sui and Wei, at least it shows that he didn't want to attack Li Mi yet, so after analysis, his next target is very likely to be Guanzhong, or the four southern counties of Guannei, I think it is more likely to be the four counties of Guannan, in fact, it is a continuation of his capture of Huining County. ”

Xiao Yu's analysis was very thorough, Li Yuan's heart was a little heavy, after the Sui army captured Huining County, in fact, what he was most worried about was whether Yang Yuanqing would continue to attack the four counties of Guannan, Honghua County, Anding County, Beidi County and Shang County.

If the four counties of Guannan are captured, then Guanzhong will face a great strategic threat, and the Tang Dynasty will most likely have to move the capital, and finally lose Guanzhong, Longyou and Hexi.

This invisible pressure made Li Yuan often wake up in his dreams, but he was unwilling to face it and think about it.

Today's second sons, Shimin and Xiao Yu, make him no longer able to deceive himself, and can only be forced to face the crisis.

At this time, Li Shimin saw his father's worries, and continued to persuade: "Father, I think God is favoring the Tang Dynasty, at this moment of crisis, God has given us another chance, let the Turks invade the Sui Dynasty from the north, Father, such an opportunity will really not come in the future, if we don't seize this opportunity, we will regret it for the rest of our lives." ”

Li Yuan finally sighed, "Then tell me about your plan!" ”

Li Shimin's spirits perked up, his father was already willing to listen to him and said that the plan, then the matter was eyebrow-raising, he already had a case, and hurriedly bowed down and said: "Father, the plan of the sons is very simple, to seize the interests as much as possible, Yan'an County and Huining County must be taken, as for Diaoyin County, Shuofang County and Yanchuan County because the population is too small, there is no strategic value, you can ignore it for the time being, the sons feel that it is best to take Lingwu County, now the population of Fengzhou is also concentrated in Lingwu County, if we can take Lingwu County, we can not have territory, Move all the population of Fengzhou and Lingwu County into Guanzhong, seize the population is the key, and then drive the Sui army back to the east of the Yellow River, then the entire Guannei Road will be our territory, which will completely change our current passive situation. ”

In fact, Li Yuan has always been obsessed with Hedong Dao, Taiyuan is where he started, and he dreamed of taking it back, he interrupted Li Shimin's exposition and asked: "What about Hedong Dao, haven't you considered it?" ”

Li Shimin shook his head, "After the Sui army fights with the Turks, even if it can defeat the Turks in the end, the Sui army will inevitably suffer great losses, in this case, they will only keep their core interests, from the perspective of Yang Yuanqing's heavy defense in Hedong County and Hanoi County, Hedong Road is the core interests of the Sui Dynasty, Yang Yuanqing will fight to the death with us, but if we don't move his core interests and only take Guannei Dao, then Yang Yuanqing will forbear, and will eventually recognize this outcome, and we will have time to expand the army and enhance our strength." , then the situation of Sui and Tang will be formed. ”

Li Yuan thought about it, looked at Xiao Yu again, and asked for his opinion, Xiao Yu pondered for a long time and said, "I think that I can use this opportunity to take Luoyang." ”

Li Yuan was shocked, he slowly closed his eyes, and said slowly after a long time: "You let me think about it again!" ”……

Li Yuan stood in front of the window with his hands behind his back, staring at the glorious palace of Taiji Palace, and pondered for a long time, he had actually been convinced, it was true, Yang Yuanqing would not let go of the Tang Dynasty because of his fear.

Sooner or later, he will still have to face the large-scale attack of the Sui Dynasty, first of all, the four counties of Guannan are not guaranteed, rather than move the capital miserably and miserably in the future, it is better to be ruthless now, seize the opportunity of the Turkic invasion of the south, and seize Guannei Dao and Luoyang.

In fact, there is a more important reason, he has been unfavorable to the Sui war for a long time, which has caused widespread dissatisfaction among the Guanlong nobles, and he even knows that the lonely family secretly sent grain to the north, if he doesn't do anything, the Guanlong nobles will completely abandon the Tang Dynasty, then the foundation of the Tang Dynasty will collapse, and the Tang Dynasty will be finished.

Whether he wants to take this step or not, no matter what the consequences are, he must go out, thinking of this, Li Yuan finally made up his mind, he wanted to use the 300,000 soldiers of the Tang Dynasty to seize Guannei Dao and Luoyang
