It's time to take a look at the situation on the Taiyuan army's side, if you talk about Dou Jiande's reinforcements? Fortunately, the news that was blocked by Luo Yi was a disaster for Li Jiancheng and the Taiyuan Army, then the news that the main force of the Yang Army was completed by Chen Fuliang within one day was definitely a bolt from the blue for Li Jiancheng and the Taiyuan Army.

And what is even more sad is that the news of the fiasco of the main force of the Dingyang army and the capture of Liu Wuzhou was the first to be brought back to Taiyuan City by Li Er, so after hearing these reports, Li Jiancheng forgot to take the opportunity to pack up his second brother who was eating inside and out, and stood on the city wall with a sluggish expression, unable to make a sound for a long time, and finally sighed after Li Jiancheng stumbled and fell on the city wall. Li Yuanji, Li Baiju and others left the scene under the cover of others, and returned to Taiyuan City with a cheeky face.

Li Jiancheng didn't have time to pay attention to Li Er, and on the same night, Li Shentong, the cousin who guarded Xi City, sent Li Jiancheng a letter asking for help, saying that he really couldn't resist Liu Heimin's violent attack, and the city was about to be broken, so he asked Li Jiancheng to send him reinforcements to help quickly, otherwise, Li Shentong would definitely not be able to defend Xi City.

Xicheng is the rule of Xihe County, there is a small amount of money and food, and it is the only way to contact Lishi County, once it falls, Lishi County, which is being attacked by Liang Division, will definitely not be able to keep it, whether it is from a strategic point of view or a tactical point of view, Li Jiancheng should send reinforcements to Xicheng. But this time with the exception, Li Jiancheng not only did not send reinforcements to Li Shentong, but also sent an order to Li Shentong, "Hold on with all your might!" If the city is unfortunately broken, you can lead the army to move to Lishi! ”

Of course, Li Jiancheng did this for a reason, and the reason was nothing else, it was that Li Jiancheng really couldn't take out the army to reinforce Li Shentong, and the 65,000 troops of the thirteenth general who had been accumulated with great difficulty in the dismal management had never dared to fight head-on with the main force of the Sui army, and now only about half of them were left, and there were still 5,000 of them taken by Li Shentong to the right flank battlefield where Xicheng and Lishi were located, and the actual strength in Taiyuan City, including the wounded soldiers, was only about 27,000, and this point of strength was still insufficient to protect itself in front of the main force of the Sui army, where does Li Jiancheng still dare to divide the army?

On the afternoon of June 26, the day after Li Er fled back to Taiyuan City, the main camp of the Sui army re-dug the earthen dam that had been temporarily built in the Dongwu River to restore the river to its normal state, and then built a number of wooden bridges and pontoon bridges overnight.

Here we must introduce the situation of the ancient Taiyuan city, the Taiyuan city before the Song Dynasty is located in the Jinyuan District in the south of the current Taiyuan City, located between the east and west mountains, and the east and west cities are built with Fen water, which occupies most of the horizontal space, only the north and south are open, and can be used for garrison operations. So. Whether the main force of the Sui army will adopt water attack tactics next can be seen at a glance from the position of the new battalion of the main force of the Sui army!

If the new battalion of the main force of the Sui army chooses to be in the southern suburbs of Taiyuan City, downstream of Fenshui, then Li Jiancheng can sit back and relax, because the main force of the Sui army, which is further downstream, will definitely not artificially create floods and endanger the safety of the camp of the Sui army. But if the new battalion of the main force of the Sui army chose to be north of Taiyuan City, upstream of Fenshui, then Li Jiancheng and the Taiyuan army could only pray to the gods and worship the Buddha, and begged the gods to let Chen Fu's conscience find out, and not to build any dams and dig up the Fenshui embankment to irrigate Taiyuan.

In the early morning of the next day, the main force of the Sui army under the leadership of Li Jing marched north one by one, and the advance army first crossed the Dongwu River, and then bypassed the southeast corner of Taiyuan City and slowly went north, and gradually opened to the Chongsheng Temple in the northeast corner of Taiyuan to stop, and immediately began to build fences and antlers, and built imperial fortifications. Seeing this situation on the city wall, Li Jiancheng's face was so gloomy that he could almost drip, and he kept saying in his heart: "Brother Ying Liangxian, are you really ruthless about this?" In Taiyuan City, there are hundreds of thousands of innocent people! ”

Most of the civil and military officers of the Taiyuan army who accompanied Li Jiancheng to watch the enemy situation also had gloomy faces and kept talking in low voices. Some people say that this must be a sign that the main force of the Sui army is preparing to flood the city with water, and some people say that Chen Fuliang has always advocated morality; It should not adopt such a cruel tactic as flooding Taiyuan, and the Chongsheng Temple is just to take a condescending position and command the siege conveniently; There was some controversy between them, but no one spoke loudly, disturbing Li Jiancheng, who was obviously in a very bad mood, until Li Jiancheng's baby brother Li Yuanji appeared.
