Yuwen Stone is known for his strategy, good at scheming and decisive, and has a clear judgment of the current situation.

Hangu Pass, this fortress is about the success or failure of the army.

If you don't join up with the heirs of Chang'an who stayed behind as soon as possible, Hangu Pass will be occupied by the King of Qin, and the forces of the Yuwen family will be divided on the east and west sides of the checkpoint, and they will fight on two fronts, and it will be easy to suffer heavy losses from the imperial army.

In the early spring, the cold wind was blowing, the earth was vast, Yuwenshi led the troops, evacuated Luoyang non-stop, and rushed to Hangu Pass.

Along the way, he often met with the lone Yu Lin Wei, and through the mouth of Yu Lin Wei, he learned that the King of Qin also quickly went to Hangu Pass.

King Qin went straight to Hangu Pass, his intention was obvious, how could Yuwenshi dare to delay.

After thinking about it again and again, he sent Bo Yanjun to lead the elite cavalry to take a shortcut to Hangu Pass, hoping that King Qin would take the lead in occupying Hangu Pass before entering the pass.

Chang'an, the imperial city of the Tang Dynasty. The walls were destroyed and the defenders were killed and wounded.

Yuwen Tai, Yuwen Xuanying, Yuwen Xuanjie, and Yuwen Xuanwu united forces loyal to the Yuwen family according to the plan, coerced the left and right Jin Wuwei generals, the right leading army Wei, Bai Huanyu, Zhao Yunsheng, and Cao Cen Ping to raise troops in Chang'an.

The troops were menacing, like the wind and clouds, Bai Huanyu, Zhao Yunsheng, and Cao Cen Ping led the troops, occupied the camp of the 16th Guards, and killed and captured the 16th Guards.

Yuwen Tai, Yuwen Xuanying, led the left prison guards, and allegiance to the forces of the Yuwen family, stormed the Shenwuwei and Longwuwei military camps.

Fortunately, the emperor conspired with He Hengrui and was already prepared.

After learning that the members of the Yuwen family were gradually evacuating Chang'an, they secretly took precautions.

He Hengrui went to the Zuo Servant Mansion, clarified the situation, invited Gao Xiaoyun, and stationed Shenwuwei and Longwuwei military camps in advance.

Ordered the army, garrisoned silently into Chang'an, Yuwen Tai, Yuwen Xuanying captured the camp, and fully emptied.

Yuwen Xuanwu and Yuwen Xuanjie, who attacked Chang'an, were tragically damaged by Shenwuwei and Longwuwei, and suffered serious losses.

The army was frustrated and did not directly capture Chang'an, and Yuwentai realized the seriousness of the problem.

He personally led the Yuwen family to raise the dead, sat in the south of Chang'an, issued an edict, left and right Jin Wuwei, and left and right leading the army guard, and continued to attack Chang'an.

With this, Yuwen Xuanying was ordered to lead the troops, through the north of Tongguan, to Changle Palace, Yuwen Xuanjie led the troops to the ancient city of Chang'an, Yuwen Xuanwu left Chang'an, went to Hangu Pass, and captured the checkpoint!

Loyal to the generals of the Yuwen family, they soon occupied, Fengyi County, Xiatai County, Liyang County, a series of deployments, so that Chang'an became an isolated city.

Soon, Yuwen Xuanwu sent back the news and successfully took control of Hangu Pass.

At this time, without breaking through Chang'an, entering the palace, and capturing the emperor alive, Yuwentai was still full of confidence and the victory was in his hands.

Hangu Pass is in hand, the soldiers of Kanto are difficult to kill into the pass, Chang'an has become a lonely city, there is no reinforcement, and sooner or later it will fall into the hands of the Yuwen family.

Chang'an Imperial Palace, sitting on thousands of acres, magnificent and huge, the replacement of emperors, witnessing the years. The battle of Bing Ge has long been accustomed to it.

However, in the temple there was restlessness and panic.

In Chang'an City, except for the Shenwu Guard, Long Wuwei, the right prison guard, and 200,000 male soldiers, there are no other soldiers and horses.

On the other hand, Yuwen's family, the left prison guards controlled by Yuwen Xuanying, and tens of thousands of dead soldiers, left and right Jin Wuwei, right leading military guards, and refuge generals, totaling nearly 300,000 soldiers and horses.

Regardless of the number, or morale, it far exceeds that of the imperial court.

Chang'an City is in a delicate situation, the day of breaking the city can be expected, and the people are panicking.

In the imperial court, there was no preparation for the sudden rise of troops, and the battle of defending the city and repelling the Yuwen family still suffered heavy casualties.

On the fourth day of the first lunar month, the day after Yuwen's army, Emperor Yang Mingkun woke up and learned that Yuwen's army was raised, and the soldiers surrounded Chang'an, vomiting blood on the spot.

The imperial doctor treated urgently, stabilized his mood a little, and in his anger, he ordered He Hengrui to kill the people in Chang'an City and related to the Yuwen family, and in the court, he also killed and dismissed many officials loyal to the Yuwen family.

On the fifth day of the first month, the generals of Jin Wuwei called for war outside the city, insulted the royal family, and the emperor vomited blood again, fortunately He Hengrui and Gao Xiaoyun led the troops to block and repel the opponent's attack.

That night, Yuwen Tai personally led a large army to attack the city, the battle lasted for half the night, the losses on both sides were serious, and the city wall near the south gate partially collapsed.

Gao Xiaoyun personally led the dragon Wuwei to fight, and the two sides fought repeatedly, and at sunset, Yuwen Tai led the troops to evacuate.

The battle was tight, the walls were stained with blood, and the soldiers were tired, so the king of Qi ordered the craftsmen to take the opportunity to repair the city.

The seventh night of the first month. In the Jinluan Palace, Yang Mingkun barely supported the Shang Dynasty, the King of Xiaoyao, the Great Prince, the King of Qi, the King of Wu, the Zhongshu Order, the left and right servants, and a few loyal court officials to discuss the strategy of defending against the enemy.

At this time, in addition to the Zhongshu order and the left servant shooting, the majority of the ministers in the palace, and the hundred officials were uneasy.

Yang Mingkun was treated with medicine, his body could barely support it, his cold eyes swept across the officials, and his voice was weak: "The Yuwen family raised troops, the generals of the Sixteen Guards betrayed, Gyeonggi Province, Dugi Province, except for Chang'an, all fell into the hands of the Yuwen family, surrounded by Yuwentai, Chang'an became a lonely city, losing contact with the outside world, you Aiqing, what is the current good way?"

The Yuwen family raised troops, beyond expectations, the court was defenseless, and the other party was like a bamboo, and the wind and clouds were torn down, causing serious disasters to the court.

Chang'an City became a lonely city, Hangu Pass was lost, the life and death of the King of Qin and the King of Shu were uncertain, and the troops stationed everywhere had not yet learned of the rebellion of the Yuwen family, seeing that Chang'an was in danger, it would be broken by the Yuwen family sooner or later.

Yang Mingkun was furious, it was difficult to prevent thieves day and night, and Yuwenshi finally tore his face with the court.

For a while, the hall was silent, and the officials were speechless.

Even Yang Hong and He Hengrui, who regarded quelling the Yuwen family's rebellion as a restoration of the crown prince's position, had no idea.

The situation is out of control, beyond control, Chang'an is in danger, especially the left and right Jin Wuwei, the right leading army Wei rebellion, completely beyond Yang Hong, He Hengrui expected.

At this time, they were full of remorse, but they didn't dare to say it, for fear of attracting the emperor's punishment.

In silence, Yang Hong took the lead in standing up. His expression was nervous, his tone was lonely, and he said: "Father, the generals of the sixteen guards are about to defect, causing unease in the imperial court. But at present, in the imperial court, he still controls Shenwuwei, Long Wuwei, and the right prison guard, with a total of 200,000 male soldiers.

Moreover. Chang'an City is easy to defend and difficult to attack, Yuwen Tai is attacking the city, and in a short time, I am afraid that it will be obstructed."

"In the short term, in the long term?" Yang Mingkun slapped his palm on the dragon case, his face was hideous, and he asked coldly: "Yuwen Tai's troops besieged Chang'an and occupied Hangu, if they cooperate closely with Yuwenshi, within more than a month, this Chang'an is afraid of being broken, not to mention, according to rumors outside the city, the army under the account of the King of Qin and the King of Shu was hit hard, and east of Hangu Pass, no one can help the Yuwen family, the Yang family, and the country will fall into the hands of the rebellious ministers and thieves."

Yang Mingkun's heart is like a mirror, the border plug festival has not yet been solved, and the Yuwen family has raised troops in Luoyang, besieging Chang'an, and all parties are afraid that they will take advantage of the fire to rob.

If the rebellion cannot be quelled before all parties send troops, the Tang Dynasty is afraid that it will fall apart.
