If the Sui and Tang dynasties, Li Mi sent troops to the Central Plains to contain the Sui army from the east, and if the Sui army attacked Wei, the Tang army attacked Hedong and Guannei from the west, forcing the Sui army to withdraw. [.]

This is actually a copy of the Three Kingdoms of Wei, Shu and Wu back then, forming a three-legged tripod, and the confrontation situation is likely to continue for decades, which is the result that Yang Yuanqing never wants to see, so he must break the trend of the Three Kingdoms before Tang and Wei form an alliance, and first destroy the weak Wei Li Mi, so that the Three Kingdoms will become a two-strong showdown.

But Yang Yuanqing also knew that even if Tang and Wei had not yet formed an alliance, the Tang Dynasty would see the danger of the Sui army attacking Wei and the opportunity of the Sui army's insufficient strength, would they seize this opportunity? Although the Tang Dynasty had already shown a cowardly posture and may not be very big, Yang Yuanqing did not want to take any risks in this decisive strategy.

He recruited 100,000 new soldiers to defend Hedong and Hebei, and the general Qin Qiong led an army of 100,000 troops into Guannei Dao, plus 30,000 garrisons led by Sheng Yanshi of Huining County, pressed the pass from the east and west fronts, forcing the Tang army not to dare to act rashly.

This is just a strategy, and tactically, Qin Qiong also used the strategy discussed with Yang Yuanqing in advance, and played the Phnom Penh Red Eagle Army Flag, which means that Yang Yuanqing himself is also in the pass.

The 130,000 Sui Dynasty soldiers entered the pass, sharpened their swords, and pointed directly at the pass, which put the Tang court under great pressure, but on the other hand, the strong threat of the Sui army also eased the sharp contradictions between the Li father and son.

The contradiction between Li Yuan and Li Shimin has reached an irreconcilable level, and Li Shimin left Beijing without authorization and went to Fufeng County. Nominally, he went to train troops, but in fact he controlled the 50,000 jīng soldiers in Fufeng County, which made Li Yuan's plan to put Li Shimin under house arrest and completely deprive him of military power.

Li Yuan was very annoyed, on the one hand, he ordered Li Shentong, who was stationed in Tongguan, to take over the 30,000 jīng soldiers stationed in Fengyi County, and on the other hand, Li Yuan issued nine gold medals in a row to order Li Shimin to enter Beijing, but Li Shimin just ignored it

Seeing that the high-level contradictions in the Tang Dynasty were about to intensify. However, the strong entry of the Sui army into the Guannei temporarily alleviated this contradiction, and Li Yuan renamed Li Shimin as the marshal of the Western Route Army, which was a reluctance to admit his control over the 50,000 army......

Yong County, Fufeng County. This is the county seat of Fufeng County, and the 50,000 troops controlled by Li Shimin are stationed in Dasanguan with the exception of the eldest grandson Wuji who led 10,000 troops to be stationed in Dasanguan. The remaining 40,000 troops were all stationed near Yongxian, and Li Shimin did not live in the county seat, but in the barracks, firmly controlling this army.

In Bai Sè's handsome tent, Li Shimin stood in front of a huge woodcarved map with his hands in his hands, and was silent for a long time, although he was not in Chang'an, he could still get the latest from Tang Feng's hands, including the urgent express sent by Li Xiaogong this morning.

Stringing together all kinds of bits and pieces of information, Li Shimin seems to have discovered a huge crisis. It's just that he still has some things he hasn't figured out, and he needs to sort out his thoughts.

At this time, Fang Xuanling slowly walked to his side and said in a low voice: "Does Your Highness think that Yang Yuanqing is not in the pass, and the Red Eagle Banner in Phnom Penh is just a false tactic of the Sui army." ”

Li Shimin nodded. He said in a deep voice: "I always feel that Xiao Mo and Du Fuwei are a little weird to jointly attack Li Mi at this time, it seems that their actions have something to do with the Sui army's entry into the Guanneidao. ”

"Why does Your Highness think that?"

"I'm wondering, why are Xiao Mo and Du Fuwei not afraid of the Tang Army attacking their back road? As a result, news came from Li Xiaogong's side that Xu Shiji led an army of 40,000 troops to garrison Xinye County, which was less than 100 miles away from Xiangyang, which made me suddenly think. Xiao Mo and Du Fuwei's attack on Li Mi was actually arranged by Yang Yuanqing, so Yang Yuanqing came to solve the threat of the Tang army behind them for them, so Yang Yuanqing's real target was not the Tang Dynasty, but Li Mi, is that so? ”

"His Highness's thoughtfulness is admirable!"

Fang Xuanling praised from the bottom of his heart, and said: "Actually, I also think that Xiao Mo and Du Fuwei jointly attacked Li Mi, because in the last battle, Du Fuwei and Xiao Mo also suffered heavy losses, and even Fu Gongyou was killed, it has only been two months, how could Du Fuwei relieve his breath and attack Li Mi again, so Xiao Du uniting is actually not their intention, but should be the result of Yang Yuanqing forcing them to send troops." ”

After Fang Xuanling's words, Li Shimin's thinking became clearer, but he still had something to understand, he pointed to Qingzhou on the map and said: "The only thing I can't figure out is that since Yang Yuanqing wants to fight Li Mi, why don't you take Qingzhou first, across a Qingzhou, how can he send troops from the north, if the troops enter Peng County, isn't he afraid that Liu Heimin will attack from behind?" ”

Fang Xuanling smiled faintly, "This is Yang Yuanqing's cleverness, confusing Li Mi, thinking that Yang Yuanqing Qingzhou has not been taken and will not attack Jiangnan, but he has forgotten the most critical point and how Yang Yuanqing took Gaoli." ”

Li Shimin was taken aback, he hurriedly looked at it carefully on the map, drawing a route from the Luhe military port of the Sui army, he couldn't help but gasp, at this time, Li Shimin's everything suddenly came through, the Xiao Du coalition army was just a decoy, and Li Mi's real danger was on the waterway.

"No way!"

Li Shimin immediately decided: "This matter should be notified to Li Mi immediately, so that he can prevent the Sui army from attacking from the waterway." ”

Fang Xuanling sighed, "Your Highness, I'm afraid it's too late." ”

"This ......"

Li Shimin's face showed disappointment, and he said worriedly: "If Li Mi is destroyed, then the Sui army will have no containment in the east, and in the next step, the Sui army will definitely surround Guanzhong, sir, we are in danger!" ”

Fang Xuanling said slowly: "Maybe there is another strategy that can save the overall situation, but I'm afraid that the saint will not be willing." ”

Li Shimin groaned slightly, his brows furrowed, "Mr. is ...... Sending troops to the Central Plains? ”

Fang Xuanling nodded, "Send troops to the Central Plains and force Xu Shiji to retreat, so that Li Xiaogong can attack Xiao Mo and Du Fuwei from behind, and save Li Mi's decline, maybe Li Mi can still have a glimmer of hope." ”

Li Shimin took a few steps behind his back, he also knew that it was difficult to persuade his father at this time, but the situation was critical, and he had to give it a try no matter what.

"Then I'll write a letter to Xiao Xiangguo." ……

At present, there are 150,000 garrisons in the entire Guanzhong area, in addition to the 30,000 troops in Feng Yi County and 50,000 jīng soldiers in Fufeng County, there are 80,000 garrisons in Chang'an City, led by Li Xiaoji, stationed in Bashang.

In addition, Chai Shao led 30,000 troops stationed in Shangjun and Beidi County, and there were 20,000 garrisons in Longxi County and Hehuang area, and 200,000 troops were distributed around Guanzhong, building Guanzhong's defense like an iron bucket.

On this morning, after the morning dynasty dispersed, Xiao Yu hurried to Li Yuan's imperial study, he received Li Shimin's handwritten letter very late yesterday, in which Li Shimin mentioned that Yang Yuanqing was likely to go south from the sea and attack Jiangdu City, although Li Shimin was just guessing, but Xiao Yu also felt that this possibility was very large, and with Yang Yuanqing's penchant for trickery, he was very likely to take this move.

What's more important is that Xiao Yu agrees with Li Shimin's point of view, Li Mi in the East is extremely important, and maintaining a three-legged stand will help stabilize the current pattern, which Xiao Yu must make clear to Li Yuan.

Xiao Yu walked all the way quickly, walked into the Wude Palace, and soon came to the imperial study, he arched his hand to the eunuch on duty at the door, "Please report to the saint for me, just say that Xiao Yu has something urgent to see!" ”

The eunuch nodded and went in, and came out after a moment and said, "Xiao Xiangguo, the Holy Lord invites you to go in." ”

Xiao Yu tidied up her clothes and hat a little, and then straightened out her thoughts a little, and then walked into the imperial study.

In the imperial study, Li Yuan was discussing with the crown prince about chūn ploughing, there was a serious shortage of ploughing cattle and horses in various parts of the Tang Dynasty, and the magistrates asked the imperial court for help, Li Jiancheng meant that he could temporarily borrow some horses from the army urgently, and then return the horses to the army after chūn ploughing, which made Li Yuan very embarrassed.

After all, the 100,000 Sui army was in the northern army to press Guanzhong, and asked him to lend the army horses for chūn farming, which is probably inappropriate, Li Yuan thought for a while and said: "Guanlong is all winter wheat, and there is no need to cultivate it for a day, so I will send Guanlong's ploughing cattle and livestock to Hanzhong and Bashu to ensure that the rice can be planted in time, do you think this will work?" ”

Li Jiancheng said: "Maybe we can buy some cattle from the Qiang people in Xishu to solve the burning eyebrow, what does my father think?" ”

Li Yuan thought for a while and said with a smile: "That's okay, if you can ask them to buy some horses, that's the best." ”

"Erchen can let the officials in Shuzhong give it a try."

At this moment, Xiao Yu walked in quickly, bowed down and saluted, "Weichen see Your Majesty!" ”

"Is there anything important about Xiao Xiangguo?" Li Yuan asked softly, he had always valued Xiao Yu very much.

Xiao Yu didn't dare to say that Li Shimin wrote to him, especially in the presence of Li Jiancheng, it was best to avoid Li Shimin, he hurriedly said: "Back to Your Majesty, Weichen considered last night, Xiao Du's coalition army attacked Li Mi, it is very likely that it was just a bait, Weichen can conclude that Yang Yuanqing has sent troops from the sea to attack the Wei army from behind, Your Majesty, the Wei army is in danger!" ”

In fact, Li Mi's important xìng, Li Yuan also knew that everyone discussed it at the court meeting, with Li Mi containing Yang Yuanqing in the east, the Sui army did not dare to attack the Tang Dynasty with all its might, this is already a consensus, Li Yuan also sighed slightly, "Even so, I'm afraid it's too late to inform Li Mi, from Chang'an to Jiangdu, it will take twenty days at the earliest, and I'm afraid the battle will already be over by then." ”

"Your Majesty, there is still a way to save it!"

"What's the solution?" Li Yuan seemed to sense something, and he glanced at Xiao Yu with a smile.

"Your Majesty, we can send troops to the Central Plains and force the Sui army of Nanyang County to retreat, so that King Jing's army can attack the Xiao Du coalition army from behind......"

"Impossible!"

Without waiting for Xiao Yu to finish speaking, Li Yuan shook his head without any room for negotiation, "I gave up such interests to sign an agreement with the Sui Dynasty, I will never ruin the agreement and let Yang Yuanqing seize our handle again." ”
