Such a big thing happened in Yanmen Pass, the Turks mobilized hundreds of thousands of troops to storm Yanmen Pass, besieging Luanjia, even if the emperor did not send letters outside, there were countless people outside who got the news.

Putting aside others for the time being, Yang Yuan, the king of Qi who was left in Lao County by Emperor Sui, and Li Yuan, the governor of Hedong, Shanxi, both got the news.

Yang Xuan, the king of Qi, only has 30,000 soldiers and horses in his hands, and Lao County is also one of the forty-one cities of Yanmen Pass, but the terrain of Lao County is precipitous, the territory is not large, it is easy to defend and difficult to attack, and there is still some distance from Yanmen City.

Let him take these 30,000 soldiers and rush directly to the king of Yanmen Guanqin, he neither has such courage nor thinks he has such ability, but this person is known as the prince who is most like Emperor Yang of Sui, and he does have some ability.

He couldn't go to Yanmen Pass in person, but he didn't let his father's safety go without hesitation, he built a fort here in preparation for receiving the emperor, and at the same time tried to send the emperor's distress letter, uh, to be precise, the emperor's own dispatch order, that is, any soldier who received this letter should try to go to the rescue of the king of Qin's order as soon as possible, and distribute it to the generals around Yanmen as quickly as possible.

Among them, Yun Dingxing and Wang Shichong, the generals of Zuotunwei, both received this order to send generals, among which Yun Dingxing had the most soldiers and horses in his hands, which was the closest to Yanmen Pass.

Yun Dingxing has an army of 80,000 in his hands, plus soldiers and horses from other places, as long as Emperor Yang's side can hold on for some more time, the difficulty of Yanmen Pass should be solved.

Not to mention Yang Hui's movements, but to say that Li Yuan, who served as the lieutenant of Hedong, Shanxi, has only been in office for a few months, and he has few soldiers and horses in his hands, and he wants to go to Yanmen Pass to rescue the emperor.

But it's not okay to watch the emperor being trapped, if the emperor has any accidents, the court doesn't know what kind of chaos will happen.

If the court is in chaos, the current power of the Li family's father and son alone is not enough to protect themselves, Li Yuan understands this truth, and Li Erlang, who is with his father, naturally understands it.

After a little thought, he ran to his father to ask for his life, and decided to go alone to rescue the emperor.

"Erlang, you, what are your plans?" Li Yuan was taken aback, his son's courage was commendable, but if there was no good plan, he couldn't watch his son go to his death.

"Father, General Zuotunwei was ordered to rush to Yanmen Pass, and when his son accompanied His Majesty on the Eastern Expedition last year, he happened to serve under General Yun and had a certain friendship with him."

"My son will go to General Touyun's troops and go to Yanmen Pass with him." Li Erlang said.

"Erlang, that Yun Dingxing is a villain who can only drill camps, he can take the position of a general, most of them rely on being able to pat horses, I am afraid that he will not be able to save ......His Majesty alone," Li Yuan exclaimed.

Yun Dingxing is a person who has a little status in the dynasty and doesn't know that there are not many people who don't know him, he was the father-in-law of the former prince Yang Yong, and with his identity, he was able to become Emperor Yang's favored minister, just this point, it can be seen how shameless this person is.

"Father, it's true that Yun Dingxing's character is not very good, but he still has a little ability, otherwise, how can he stand in the court for more than ten years without decay just by relying on shamelessness? Father, please rest assured, the son has a sense of proportion. ”

"My son can follow the army and serve the king, if he can make meritorious contributions, he will definitely be able to let His Majesty eliminate the suspicion and dissatisfaction with my Li family, once Your Majesty can eliminate the estrangement between my father and our Li family, let my father stay in Taiyuan for a long time, and let our brothers leave Kyoto......"

"Our family doesn't have to live with fear like now." Li Erlang met his father's gaze and said with a firm face.

"Erlang ......" Li Yuan looked at his seventeen-year-old son, his face was complicated, guilty and worried.

Li Erlang said goodbye to Li Yuan, spent two days, caught up with Yun Dingxing, who was marching towards Yanmen Pass, Li Yuan said that Yun Dingxing was a villain and did not wronged him, although he was ordered by the king, he had to come to Yanmen Pass to Qin Wang.

But the action is extremely negative and slow, he does not think that these tens of thousands of people alone can defeat the 200,000 Turkic army, he is only a few hundred miles away from Yanmen Pass, and he has walked for four days, and he has not yet walked halfway.

On this day, when I was thinking about how to fight this battle and how to gallop this aid, the messengers under his command came to report: "General, Li Shimin, the second langjun of the Tang State Mansion, came to visit. ”

"Li Jiaerlang? Invite him in. When Yun Dingxing heard this, his heart suddenly moved, and he immediately sent someone to bring Li Erlang here.

Last year's Eastern Expedition, his troops performed well, and after the Eastern Expedition, the emperor praised him more than once, rewarding him with countless treasures, many of which were Li Erlang's strategies.

Although this kid is not very old, he does have talent in the field of fighting, and he may have any good strategies.

Yun Dingxing procrastinated, to put it bluntly, he was greedy for life and afraid of death, and he didn't have the slightest grasp of this help.

If he can really rescue the emperor, it will be a great credit, and he naturally does not want to miss it.

For this reason, as soon as Li Erlang was brought into the military tent, Yun Dingxing greeted him with a smile: "Li Erlang, didn't you follow your father in Taiyuan, why did you come to me?" Could it be that he heard about His Majesty and was ready to come and go to Yanmen Guanqin with Yun Mou? ”

"General Hui, the people of the world do have this intention, as a courtier, how can they be indifferent when they hear that the king is besieged by foreign invaders?" Li Erlang replied.

"Hahaha, courage is commendable, but Erlang, you also know the situation now, there is too much difference between the strength of the enemy and us, and the Turks have always been good at fighting, I ......" Yun Dingxing laughed, and then changed his words.

"Shimin understands the general's worries, but this matter is not without a solution, the reason why Shibi Khan dared to surround His Majesty in Yanmen Pass is because he thought that with the natural danger of Yanmen Pass, the army that I have the ability to rescue will not be able to reach it for a while."

"But he didn't expect that the soldiers and people of our dynasty were loyal to Your Majesty, and the generals of all parties heard that the king was trapped in Yanmen, and they immediately forgot their lives and died, and struggled to advance towards Yanmen Pass, and the general was the closest person to Yanmen Pass."

"In the name of the general, when we go, we should increase the number of flags and drums in the army, and stretch the ranks of the marching troops as long as possible.

"After all, Shibi Khan doesn't know how many soldiers and horses our army has gathered, and seeing our army in such a position, coupled with the reinforcements that are rushing here from other places, I will inevitably have doubts and uneasiness in my heart."

"Of course, if you want the enemy to retreat, it will definitely not work with bluff alone, please ask the general to give Shimin thousands of elite soldiers, and when the vanguard of the army is approaching Yanmen Pass, Shimin is willing to rush into the enemy camp with the vanguard and disrupt their position..... Li Erlang said slowly.

"Li Erlang, I understand this bluff intention, but once the hand-to-hand battle is met, you, are you sure you want to take Xiang Qian's soldiers and horses to be the vanguard?" After Yun Dingxing listened, he stared at Li Erlang with wide eyes for a long time before he took a sentence with a little stutter.
