Later scholars found out from the "History of the Great Sui Empire" that in the first year of Emperor Wu (Yang Hui) in China, there was a tragedy in Chang'an, the pseudo-Tang capital, and in the Xuanwu Gate Change, Li Shimin killed his own brother and the prince to build it, and took over the power to confront the Great Sui!

"And that's the end? The lonely melon seeds haven't been eaten yet, and this farce that should have been 'earth-shattering and crying ghosts and gods' has ended like this? Yang Jian was extremely disappointed after receiving the information, he thought that the two brothers of the Li family would have a battle in the open and secret and then use force after their respective tricks were exhausted, who knew that they actually did not act according to common sense, and went directly to this topic, and directly led people to war, and he gave them time to fight slowly.

"Go, get a few generals!" Yang Yun instructed Zhou Han to invite Qin Shubao and others, now that the Xuanwu Gate Revolution has come to an end, it is time to work after watching the play.

"Your Majesty, are you going to attack, the ministers are waiting for the idle birds, and this time you have to let the ministers be the vanguard!" Cheng Yanjin shouted from outside the big tent, fearing that the position of the pioneer would be taken away.

"Biting Jin, you ......" Qin Qiong glanced at Cheng Biting Jin, he is still so frizzy when he is a general, and he doesn't know how to count etiquette, and Yang Yong is no longer a prince, but an emperor.

"It's okay, I'm calling you here, it's really to arrange for the continuation of the attack......"

"Your Majesty, give me Lao Cheng 20,000 soldiers and horses to ensure that they will be killed under Chang'an City!" Before Yang Jian finished speaking, Cheng Yanjin was in a hurry to ask for battle.

"Okay, I know that Zhijie is brave, but there are only 20,000 people, so I ......" Yang Jian suddenly dragged out his words, meaning that you can't hit Chang'an with 20,000 yuan.

"Your Majesty, the minister is willing to make a military order!" was looked down upon, Cheng Biting Jin was unhappy and wanted to use it; Establish a military writ to prove yourself.

"No, I believe you, so let's do it, I will give you 50,000 horses, and I will stop when I get to Xinfeng, can you do it?" Yang Jun pointed to a place on the map that is very close to Chang'an, Xinfeng County.

"No problem, the minister will definitely take Xinfeng to welcome His Majesty's army!" Seeing that Yang Jin promised to let him be a pioneer, Cheng Yanjin was overjoyed, as for why Yang Jin didn't let him fight under Chang'an City and wait, he didn't think about it carefully. After receiving Yang Yun's order, Cheng Yanjin happily went to lead people to battle.

"Your Majesty, why did you let the lone army of biting gold go deeper?" Qin Shubao asked suspiciously, in the same way, Luo Shixin was also puzzled, it was taboo for soldiers to go deep alone, especially for Cheng Yanjin to lead.

"Just look at the news." Yang Jun handed the news in his hand to the two of them.

Seeing the news given by Yang Xuan, Qin Shubao and Luo Shixin were full of surprise, they couldn't imagine that the pseudo-Tang Dynasty had not forgotten to fight among themselves under their powerful offensive, no wonder His Majesty wanted to stop the march, this was obviously to give them no scruples to fight for power and profit.

"Now that the puppet Tang is Li Shimin in power, if you are Li Shimin, how will you deal with my attack?" Yang Jun asked.

"Your Majesty means that the puppet Tang will shrink its forces and focus on defending Chang'an, so there will be no resistance along the way?" Qin Shubao reacted quickly.

"Yes, if Li Shimin is in power before I set out on the expedition, maybe we won't be so easy to break through the enemy's defense line now, it is precisely because now that the various armies of our Great Sui are advancing into Guanlong, the puppet Tang can no longer stop the pace of our army's advance, so they can only shrink their defenses, concentrate their forces near Chang'an, and rely on the height of Daxing to do a long-term confrontation with our army, of course, Chang'an alone can't last long, so they must have another city to echo each other, And Tongguan is the only choice, so if we want to take Chang'an as soon as possible, Tongguan must be in our hands! Yang Jun pointed out the situation faced by Li Shimin in a few words, and basically finalized their next strategy.

"Your Majesty, let the ministers lead the troops to take Tongguan!" Qin Shubao asked for battle, Chang'an naturally left it to Yang Xuan, the emperor, to break it, and Tongguan should let him fight.

"No, Tongguan is not much inferior to Daxing, and according to intelligence, Tongguan has more than 100,000 soldiers and horses at this time, and it is controlled by Li Xiaogong, according to the conventional way of fighting, it is impossible to break through without 350,000 horses, so Tongguan will be fought by the pharmacist, I believe he will have a way, you will go to Daxing with me to meet the person who killed his brother and forced his father to seize power, and recapture Daxing!" After all, Daxing was the first capital of the Great Sui, and it was occupied and renamed, which is not a glorious thing, although it is better to change the name to Chang'an, but this should also be changed by the master of the empire.

"Yes!" Qin Shubao also breathed a sigh of relief in his heart, he also knew more or less about the solidity of Tongguan, if he was really asked to attack, he was really not sure that he would be able to capture it, at most he would surround Tongguan.

"It turns out that Your Majesty is waiting for this play, no wonder, but it seems that Your Majesty has been disappointed!" After receiving Yang Jin's letter, Li Jing said that Yang Jin mentioned the reason why they stopped attacking in the letter, although he did not mention the ending of the scene in Chang'an, but Li Jing could roughly guess that the big scene was finished in only two days, and it must have been staged and then ended.

"Tongguan? With more than 100,000 of us, can we take Tongguan? Yang Yichen also read the letter, but he only paid attention to the military orders above, let them attack Tongguan, for Tongguan, he knew very well, the terrain behind Huashan was very dangerous, and there were 100,000 people stationed in it, so there were no several times the number of troops to eat, not to mention that they even captured the total number of soldiers and soldiers were only 150,000.

"Of course you can, wasn't Hongnong Palace also taken by us? Although we took advantage of the enemy's psychology of rescuing Shangluo to defeat it, although Tongguan is different from Hongnong Palace, it is a lonely city after all, and there is no lonely city in the world that cannot be broken! Li Jing said ambitiously! What's more, Tongguan is not a city, because there are no residents in it, which means that the consumption of troops inside is one less, and there is no replenishment at all!

Now the situation in Chang'an has completely changed, on the day of the Xuanwumen Change, Li Shimin completely cleared the power of the former prince Li Jiancheng, although Li Yuan is still the emperor, but the rights are all empty by Li Shimin, and he is imprisoned in Jing'an Palace, and Li Shimin is in charge of the country as the crown prince. After leading the army to defeat Yang Wengan's troops attacking Chang'an, no one dared to resist.

"Gong Zhang, please gather all the armies to gather in Chang'an, we can't let the Sui army have every chance to break through, we have to start a desperate battle with the Sui army in Chang'an!"

"Junji, you are responsible for leading 100,000 horses to the area of Gaoling Xinfeng to set up the first line of defense, and at the same time respond to the retreat of the northern army!"

"Duan Gong, you lead the forbidden army in the palace to defend the area around the Taiping Palace, and you don't know the second line of defense, so as not to prevent the enemy from attacking from the south!"

"Jing Gong, you need to be fully responsible for logistics, and at the same time, another 100,000 reserve troops will be recruited in case of emergency!" Li Shimin issued orders one after another, and now it is the most critical moment, and now the troops in his hands are stretched thin again, and there are not many people who can use them with confidence!

"The ministers must live up to their mission!" Duan Xuanzhi, Zhang Liang and the others replied with solemn expressions, they also knew that if Chang'an couldn't hold it, then they would have no other way but to keep their reputation by dying, and it would be impossible for them to be three ministers anymore, because they had been regarded as a second minister since Sui Shitang, and it was impossible to re-serve Sui with a dead skin and lazy face!

"Success or failure in this move, I hope that the princes can work together with Lonely, as long as Chang'an is still there, there is still hope!" Li Shimin doesn't need to say more, because everyone is a smart person and knows the consequences of failure.

From Chengcheng in Fengyi County to Wannian County in Jingzhao County, all the troops were withdrawn, and Cheng Yanjin was unimpeded all the way, but this was not what he wanted, what he wanted was to fight on the battlefield, and there was no war along the way, which made him unhappy in his heart.

"Alas~ I was fooled by Your Majesty again!" Seeing that he was about to reach the Xinfeng realm, Cheng Yanjin knew that he had been tricked, no wonder His Majesty agreed so easily, and he didn't ask at all, it is estimated that this time he will be laughed at by Luo Shixin's kid, but this can't be blamed on anyone, who made him too anxious, he couldn't eat hot tofu in a hurry, the ancients were honest!
