The Turks attacked the city for three consecutive days, but were repulsed by the defenders of Chang'an City. The morale of the defenders was very high, and all of this was caused by Chen Fei organizing the people to come and participate in supporting the front line, and constantly using various methods to boost morale. As a soldier in later generations, Chen Fei had also read a lot of books on political work in addition to training, so he had some insights on motivating morale. And Chen Fei called all kinds of singers in Chang'an City, as well as some of the personnel of the song and dance troupe of Taichang Temple, and then performed songs and dances for the soldiers, especially military songs. Chen Fei's "For Whom" has become the favorite song of the soldiers, because this song preaches that the soldiers are fighting to defend the people, and this song is a vernacular song, which is a song that these soldiers with relatively low culture can understand. So they all like it very much, after all, there are so few songs they can understand.

As for the leaders of these song and dance troupes, Chen Fei also let Princess Wanchun be responsible, and Princess Wanchun also became the favorite singer of the soldiers. And all this greatly improved the image of Princess Wanchun in the hearts of the soldiers, and also improved the image of the Li Tang royal family in the army, so Li Shimin was also a little surprised. However, being a Turkic is not so good.

"Damn, the Tang army in Chang'an is very tenacious, it seems that we can't break through!" Jieli scolded.

Of course, Jieli knew the current situation, he wanted to blackmail Datang before, force Datang and his relatives to pay compensation, that was because Jieli had actually speculated, and Li Shimin didn't want to take risks. Jieli is still familiar with the habits of the Central Plains people, and Jieli can easily guess that Li Shimin will not actually think about taking risks. After all, Li Shimin is the one who wants to be the emperor, and I am afraid that he does not want to take even the risk in case. But Jieli didn't expect that Li Shimin, who Chen Fei would run on inside and outside Chang'an City, was not a human being, and could only be forced to fight with the Turks.

And Jieli is also helpless now, on the one hand, this expedition to Datang is about to return in vain, which can be said to have greatly damaged his face. However, if it continues to fight like this, it is destined to be a war of attrition, and Jieli may not be able to afford it. The Turkic cavalry was also not good at attacking cities, so now they could no longer conquer Chang'an. The morale of the defenders of Chang'an was high and they were not afraid of any Turks. Now that the Turks are no longer able to conquer, it can be said that Chang'an is already a chicken rib, and it is a pity to abandon it if it is tasteless.

"Commanders, prepare to withdraw your troops back to the grassland!" Jieli said.

"Khan, is that what it is? I'm afraid we've lost a lot this time! Persistence said.

Jieli shook his head and said, "We can't win this time, this is not our grassland after all, it is the place of the Tang Dynasty." If you stay here for a long time, who knows what the results will be? ”

Jieli's worries are also reasonable, if the Turks can't solve this situation quickly, then I'm afraid that once the Tang army is encircled, then they will be finished. Although a lot of local troops have been withdrawn, the 200,000 troops are only less than one-third of Datang's army, and two-thirds of the army is still in the local area. If Chang'an City is not safe, local officials may stand by and watch, and if Chang'an City is impregnable, then I am afraid that many local officials will take the opportunity to get a rescue work.

And Jieli also probably inquired clearly, several state capitals near Chang'an have begun to form civilian volunteer armies, ready to come to Chang'an to "rescue". As for the farther state capitals, they have also begun to form civilian troops, and then they want to come to the rescue and get the merit of saving the driver. At this time in ancient times, the merit was nothing more than saving the driver, so since Chang'an is solid, who doesn't want to pick up a rescue merit in vain! So they are also keen to come to the rescue, and although this army is not elite, when hundreds of thousands of ordinary soldiers are congested, plus the 200,000 troops in the city are killed, I am afraid that it will really be destroyed.

Jieli was not a fool, and he certainly knew that the role of cavalry was to fight in motion, not to stay where and siege the city. If you want to talk about foot combat, then their Turks are inferior to the Han Chinese. Once hundreds of thousands of civil volunteers surrounded them, their 200,000 people were at risk of being wiped out in Han land.

As the Khan of the Turks, Jieli certainly knew that once the 200,000 army was wiped out here, the Turks really had no hope. Even if the Han people lose more, then the Han people can be replenished after no more than one generation. But the Turks are going to be hundreds of years, and this is the gap. Therefore, since Jieli found that Chang'an has become a chicken rib, he will not continue to fight, and taking a huge risk will not be able to bring corresponding benefits, which is obviously not a good business. Jieli was already planning to retreat, and it was the Turkic army that would be in danger if he stayed.

"The Turks have retreated!" The lookout soldier on the upper floor of Chang'an City shouted.

"The Turks have retreated, we are safe!" "The chief is safe!" "Long live the emperor!" "Long live the emperor, stay safe for a long time!"

The people of the whole city were boiling, because they were also involved in this operation to defend Chang'an, although they were only in charge of some logistics. But this made them feel honored, so they all cheered.

Li Shimin heard the news in the palace and breathed a sigh of relief, and now he has finally passed the most difficult moment of Datang.

"Turks, if I don't let you lose the country, I won't be Li Shimin!" Li Shimin clenched his fists and thought.

Although the Turks retreated this time, it was the Tang Dynasty that lost in the end, because the Tang Dynasty was the one who was invaded. As a male lord, how could Li Shimin tolerate being so insulted? The enemy's presence in the capital is a great insult and a great shame for a country. So although the Turks retreated, Li Shimin still felt very humiliated. Therefore, Li Shimin has sworn that he must destroy the Turks, so that he can wash away this shame. And history also changed because of Chen Fei, because the Tang Dynasty did not exchange wealth for peace, but repelled the Turkic attack.

"Prince, congratulations to the prince, my Tang Dynasty defeated the invasion of the Turks, which is really the first fortunate event for the founding of my Tang Dynasty! Please give the prince a banquet to the hundred officials to comfort the heroes! Someone said.

"Okay, the lonely king will give a banquet immediately, and the officials above the ninth grade in Chang'an will come to participate!" Li Shimin said.

Two days later, the banquet of the crown prince Li Shimin began, and this time even the titular emperor Li Yuan came to participate, obviously looking like the first grand event of the Tang Dynasty.
