After Li Yuan crossed the Yellow River, he lived in Changchun Palace, and there was a ready-made palace built by Emperor Yang of Sui along the way, which was simply a refreshing rhythm.

Qu Tutong saw that Li Yuan crossed the Yellow River, but he was in a hurry, he knew that Chang'an was going to be lost soon, so he hurriedly went straight to Tongguan in person, and almost ran away with his shoes all the way, so embarrassed to run all the way, but he got bad news halfway, Li Yuan had already won Tongguan, and his mouth was crooked, Chang'an was not guaranteed, which meant that his head was about to move, and Emperor Yang of Sui would definitely chop him up angrily.

Now, it is Liu Wenjing who is guarding Tongguan.

In desperation, Qu Tutong ordered his subordinates to be able to do Sang Xian and collect and pay Tongguan.

For this reason, Sang Xianhe and Liu Wenjing fought head-on, you fought to the death for a day, the two sides were evenly matched, and they couldn't win or lose at once, but Liu Wenjing was slightly at a disadvantage.

Sang Xianhe saw that Liu Wenjing was almost tortured by him, so he ordered a temporary withdrawal of the army, rest and fight again, because they themselves were too tired to breathe.

Unexpectedly, Sui Jun instead gave Liu Wenjing a chance to breathe, giving him a chance.

Liu Wenjing arranged a wave of people to quietly cross the Yellow River and penetrate the enemy's back.

The back of the Sang army was attacked, and Liu Wenjing seized the opportunity to deal a fatal blow to the enemy, defeating Ke Sang Xianhe's troops in one fell swoop. The entire army of Kuwabe was wiped out, and only Sang Xian and himself were lucky to survive

After all, Qu Tutong, who fought to the end, could not guard Chang'an's biggest barrier - Tongguan.

Qu Tutong's situation became extra embarrassing, and his heart was broken, but he still held on and continued to fight with Tang Jun.

Some people saw that the Tang army had ideals and ambitions, and that it was still powerful in fighting, so they persuaded Qu Tutong to surrender.

Qu Tutong cried and choked up: "I have received the great grace of His Majesty of the Sui Chamber, how can I easily turn my back on it, I usually take the Sui Chamber, but betray when the Sui Chamber's difficulties are in trouble, and escape the country, I must not do it, I can only repay the country with death!" He also touched his fleshy neck and said: "Here is ready to take a knife for the country!" ”

Qu Tutong wept so sincerely that he wanted to serve the country, and the soldiers were also moved to tears.

Qu Tutong is a man with integrity and principles...... It deserves the respect of men, women and children.

After occupying Tongguan, Li Yuan was more confident in capturing Chang'an, and in the days when he lived in Changchun Palace, many Sui officials came to see him and showed him affection.

Li Yuan went crazy with joy, and looked at it, the people who were willing to lick his dog were all very important officials of the Sui family: Guan Chief, Yu Zhining, An Yangwei, Yan Shigu, and Li Shimin's brother-in-law, Changsun Wuji and others, in addition to being happy, Li Yuan sealed Yu Zhining as the secretary (responsible for writing the chapter and table text), Yan Shigu was the doctor of Chaosan (the famous man Bai Juyi in history also served as this official), and the eldest grandson Wuji was the commander of the Weibei march (the commander).

Li Yuan was willingly following him for these people, and when he was smiling from ear to ear, the county magistrate of Juxian County sent someone to meet him and handed over the paperwork.

It turned out that it was his wise and brave baby daughter Princess Pingyang of the Li family (later sealed) who did something earth-shattering, when Li Yuan notified his family to find him in Jinyang and was about to start an incident, her husband Chai Shao was very sad, thinking that she was a woman, and it was inconvenient to take her all the way. There was a lot of chaos on the road, he was going to fight with people with his head, not to eat other people's wine, but to dress up and take his wife.
