Du Ruhui sighed: "Li Jiancheng, the Duke of Longxi, is also a virtuous person, but it is far from the Duke of Dunhuang and the Duke of Lingwu, and the most important thing is that he has gathered many characters around him. ”

Fang Xuanling and Du Ruhui are both conceited and talented people, although Li Jiancheng is the eldest son of Li Yuanyan, but if they take refuge in him but are not taken seriously, then they must all be better than chicken heads rather than phoenix tails.

The sun was sinking, and it was getting late.

The mountain is not high, Fang Xuanling and Du Ruhui have already gone down the mountain while talking, and some old servants with their ears behind their ears immediately greeted them, and told Fang Xuanling about Li Yin's visit, and told Li Yin that he was still waiting in the thatched pavilion not far away at this time.

Fang Xuanling put down the back basket of medicine collection, sorted out his clothes, and was about to walk to the thatched pavilion, but Du Rumei said: "Brother Xuanling, have you made a decision?" ”

Fang Xuanling nodded, and said resolutely: "If the Lingwu Duke can treat me as a national soldier, I will repay him to the country, as for the Duke of Dunhuang, he may really be a Ming Lord as you say, but if Zhong Ziqi does not meet Boya, there will be no mountains and rivers, and I can only express deep regrets." ”

Du Ruhui sighed, "You and I are friends, aren't you going to serve the two masters?" Maybe there will be some hostility in the future. ”

Fang Xuanling said with a smile: "With Keming as my opponent, it is also a happy life!" ”

In the midst of laughter, Fang Xuanling walked quickly to the thatched pavilion to meet Li Yin.

Li Yin and Fang Xuanling hit it off at first sight, and Fang Xuanling was appointed by Li Yin to join the army as a secretary and let him be his advisor. Fang Xuanling also thought that he had met his acquaintance, and since then he has done his best to Li Yin and knows everything.

On August 11, in only half a month, Li Yin and Li Shimin had led their troops to pacify the north and south of Weishui, and there was now only Chang'an as a lonely city left in the entire Jingzhao County.

Jingzhao County has 22 counties, with more than 308,400 households, which is one of the largest counties in the world.

The reason why Li Yin and Li Shimin included Weishui Nanbei into Li's pocket so quickly was because the two had basically not fought with the Sui army since the expedition from Changchun Palace, as long as the army arrived at the city gate, almost all the generals and officials defending the city surrendered obediently, so Li Yin was almost busy recruiting and surrendering these days, which made the militants in the army feel very depressed.

However, since Li Yin got Fang Xuanling's effect, the whole person has become much easier, Song Zhengben is good at strategy, but he is not very good at handling government affairs, with Fang Xuanling's help, Li Yin will hand over government affairs to Fang Xuanling every time he gets a city, Fang Xuanling can always handle things in an orderly manner, and Li Yin doesn't have to worry too much at all.

Compared with Li Yin and Li Shimin, Li Jiancheng of the Tunjun Yongfengcang is relatively easy, Li Yin and Li Shimin still have to deal with many matters of the newly occupied land, and Li Jiancheng has nothing to do since he was in the Tunjun Yongfengcang, except for meeting with some representatives of the gate valves who are eager to curry favor with the Li family.

However, on this day, Li Jiancheng suddenly received information that Qu Tutong, who was in Hedong County, heard that Li Yuan was going west to enter the customs, so he appointed Yingyanglang General and Tangyin Yaojun Su to guard Hedong Tongshou on his behalf, sent him to guard Puban, and then personally led tens of thousands of troops to Chang'an.

After Li Jiancheng learned the news, his spirit was shocked, and he was ready to do a good job to make meritorious contributions.

Although Li Jiancheng is the governor of the central and leading forces, since Taiyuan raised troops into Guanzhong, his military exploits have not been significant, not to mention that he is not as good as Li Yin, Li Shimin and Li Xiuning, and even compared with Wang Changhuan of the Left Unified Army, Liu Hongji, the commander of the unified army under Li Yin's account, and others, it is also slightly insufficient.

Li Jiancheng is the eldest son of the Li family, Li Yuan did not let him attack the city, also for his safety, and no one will say anything about it, but Li Jiancheng is still a little unwilling in his heart, eager to obtain the same military exploits as Li Yin and others, but has never had the opportunity.

Li Jiancheng immediately summoned the generals and planned to take the initiative to attack Qu Tutong, but Liu Wenjing immediately objected: "Qu Tutong is good at fighting, although our army has an advantage in numbers, but there is no certainty of victory, and we are still responsible for guarding Yongfengcang, it is really not appropriate to take the initiative to attack, as long as we successfully block its westward advance here, it will be a great achievement!" ”

Wang Changhuan, Dou Liang and other generals also agreed with Liu Wenjing's words, Li Jiancheng glanced at Liu Wenjing with a complicated mood, and had to nod in agreement. After Liu Wenjing and the others left, Li Jiancheng smashed a porcelain bottle beside him with a cold face......

Qu Tutong entered the pass from Wuguan, if he wanted to rescue Chang'an, he must first pull out the Li Jiancheng Department of the garrison Yongfengcang, but Li Jiancheng tens of thousands of troops formed a strict guard, Qu Tutong led the army to fight hard for more than ten days, with many dead and wounded, but he couldn't help Li Jiancheng's army, and finally had to withdraw to Tongguan, wanting to fight again after joining the Tongguan defenders.

However, Li Jiancheng had already sent Wang Changhui to lead his troops to suddenly attack and kill the Tongguan guards, occupying the southern city of Duwei to block Qu Tutong, Qu Tutong had to retreat to the northern city of Duwei, and Li Jiancheng's army held against Tongguan, and was no longer able to rescue Chang'an.

After Li Yuan learned of Qu Tutong's movements, he asked the generals who stayed in Hedong County to besiege Hedong County, but the Sui army held the city to the death, and the Li army failed to conquer it.

Li Yuan ordered Li Jing, who was stationed in Lishi County, to attack Longquan County in the south, less than ten days, the main force of Longquan County was defeated by Li Jing, Longquan County was captured by Li Jing, Li Yuan saw this, and let Li Jing cross the river to attack the counties in the north of Guanzhong, Li Jing led 8,000 men and horses into Fengyi County in Guanzhong, and then led the army north to attack Yan'an County.

Li Yuan ordered Liu Hongji and Yin Kaishan to divide their troops to the west to capture Fufeng County, they had 60,000 troops, crossed Weishui to the south, and stationed in Acheng, which was very close to Chang'an, so the Sui army in Chang'an City went to war, but was defeated by Liu Hongji and Yin Kaishan.

Li Yin has also pacified Weibei at this time, and then led the troops to Sizhu, Li Zhongwen, He Panren, and Xiang Shanzhi all led the people to follow Li Yin, and garrisoned the ancient city of Chang'an in the northwest of Chang'an City, only a few dozen miles away from Chang'an, with 80,000 troops who could fight, and the military order was strictly ordered, and there was no crime in autumn.

On the 28th, Li Yincong sent an envoy to report to Li Yuan, requesting that a date be agreed to attack Chang'an.

Li Yuan said to the left and right: "Qu Tutong is trapped near Tongguan and can't go west anymore, he doesn't have to worry about it!" ”

So he ordered Li Jiancheng to select the elite soldiers in Yongfeng Cang, from Xinfeng to the outskirts of Chang'an, and at the same time Li Yuan asked Li Shimin to lead the newly attached Weinan troops to march north, and finally Tun the army to Bashang, southwest of Chang'an City, arrived at the specified place on time, and obeyed the dispatch.

The battle of Chang'an is about to break out.
