Youzhou, the study of Li Yi, the king of Yan. The study room is brightly lit. Li Yi, the king of Yan, sat opposite a Turk. Li Yi said politely to the Turks: "Trouble General Zhiya Sili told your Great Khan that I have led all his main forces of Li Shimin to Youzhou, and I hope that your Great Khan will quickly send troops to attack Chang'an, the capital of the Tang Dynasty." ”

Zhiya Sili said to Li Yi: "King Yan rest assured, Li Shimin's army was led out by you, and there are less than 30,000 horses in Chang'an, I will persuade my Great Khan to abide by the agreement, do his best to fight the grassland, break through Chang'an, capture Li Shimin, and support you as the lord of the Central Plains." ”

After Li Yi heard this, he was immediately overjoyed and said: "In this way, Li Yi is here to thank Jieli Khan, and thank General Zhiya Sili." ”

A few days later, Zhiya Sili met with Jieli Khan and told him about the situation in the Central Plains.

Jieli Khan said happily: "Li Shimin really wants to get rid of Li Yi as soon as possible and establish his authority, but he was fooled." Come on, quickly gather the leaders of the tribes and attack Chang'an, the capital of the Tang Dynasty, with me. ”

In the Turkic Golden Horde, Jieli Khan was sitting on a tiger skin chair, and said to the leaders of the tribes who were drinking wine, eating meat, and talking a lot: "Ben Khan has decided to attack Chang'an, the capital of the Tang Dynasty, are you willing to follow?" ”

The chiefs of the tribes looked at each other, and they all looked at one of the leaders of the Great Tent, who sat in the first position on the left side of the head of the Jieli Khan, and had a somewhat similar appearance to the Jieli Khan, who was richly dressed and noble. His name was Turki, the nephew of Jieli Khan, the son of Shibi Khan, the late eldest brother of Jieli Khan, and he had high prestige among the Turks, and was respectfully called "Second Khan" and "Little Khan".

Jieli Khan also looked at Tuli and asked with a smile: "Second Khan, what do you say about my proposal?" ”

Tuli said hesitantly: "We have an alliance with the Tang Dynasty, they pay us tribute every year, and we will not violate them; Now, the tribe that we went south to plunder the Tang Dynasty without permission has just been forced back by Li Jing and Li Ji, at this time, the Great Khan asked us to follow you to attack the Tang Dynasty, which is probably inappropriate. ”

Jieli Khan smiled: "Covenant? When there is an equal amount of power, it is called a covenant. Now that our Great Turkic Khanate is far stronger than his Datang, the covenant has a fart, and my Great Turkic Khanate will bully him Datang whenever it wants. What can he do to me? The raiding tribe we went south had just been forced back by Li Jing and Li Ji, but Li Shimin had already taken almost all of his troops to deal with Li Yi in Youzhou, who would have thought that we would suddenly attack Chang'an, the capital of the Tang Dynasty, at this time? At this time, we were able to catch him off guard. ”

Tu Li said with a little contemplation: "Li Yi rebelled and lured out almost all of Li Shimin's troops, this is the plan of the Great Khan." ”

Jieli Khan laughed and said: "What the Second Khan said is right, this is exactly what I and Li Yi planned, Li Yi is responsible for luring Li Shimin's army, and I am responsible for sneaking up on Chang'an, the capital of the Tang Dynasty. There are now less than 30,000 people in Chang'an, and for my Great Turks, capturing Chang'an is like an easy thing. Capture Chang'an of the Tang Dynasty, we will support Li Yi as the lord of the Central Plains according to the agreement, and I am willing to share the wealth of Chang'an Datang with everyone. ”

After listening to what Jieli Khan said, the leaders of the Turkic tribes suddenly had a light in their eyes. Chang'an of the Tang Dynasty, that is the imperial capital of the Tang Dynasty, there is the treasury of the Tang Dynasty, taxes for several years, and countless gold and silver treasures. With only 30,000 men to defend, if our Turkic tribes assisted the Great Khan in sending troops, how could they have hundreds of thousands of soldiers and horses? 30,000 people are not instantly crushed into powder, the treasury of the Tang Dynasty is all owned by my Great Turk, according to what the Great Khan said, and the tribes will share it, then it is not their own tribes will also have a big harvest, this transaction is worth it, capable.

So the leaders of the tribes responded to support Jieli Khan, did their best to follow Jieli Khan, and slowly rushed to Chang'an, the capital of the Tang Dynasty, through the secret passage offered by Li Yi.

In Feng Deyi's study in the Tang Dynasty, Feng Deyi and Xiao Yu sat opposite each other. Xiao Yu asked Feng Deyi: "My lord, Li Yi is reversed, you and I are both in the high position of Zaifu in the Tang Dynasty, Li Shimin trusts us, how should we plan for great things?" ”

Feng Deyi said: "Li Shimin has ascended the throne, and the new monarch we chose before may not be suitable. Now I have a new candidate, he is the son of Li Shimin, and his relationship with us is extraordinary, so he is the most suitable. It's just that there is still a stumbling block in front of him, and we have to find a way to remove it. ”

Xiao Yu said after pondering: "The new monarch that Lord Feng said, I know who it is, he has noble blood, and he is indeed the most suitable candidate for the new monarch to assist us, but this stumbling block in front of him is his eldest son Li Shimin, we want to get rid of him, it is really too difficult." ”

Feng Deyi showed an unfathomable smile and said: "It's not difficult to say this, I have a plan, which is suitable for implementation at this time." ”

Feng Deyi told Xiao Yu about his plan. Xiao Yu exclaimed: "Lord Feng is really resourceful, not only did he fall well in front of him Li Shimin, but also achieved his goal, kicking away the stumbling block for our new monarch." That's a great plan. ”

Feng Deyi stroked his beard and was also happy.

On the morning of the second day, Feng Deyi said to Li Shimin: "Now that the country has been settled, all kinds of waste are thriving, and the minister thinks that he must not raise a sword again, and the minister dares to suggest that the minister go to Youzhou to persuade Li Yi to surrender." ”

Li Shimin was stunned for a moment and asked, "You?" ”

Feng Deyi replied: "In the former Sui period, Chen and Li Yi were selected by the former Sui Sikong and Yue Gong Yang Su at the same time, and became Yang Su's staff and generals, and they worked together for many years and had some friendships. ”

Li Shimin glanced at Feng Deyi, who was nearly seventy years old and had gray hair, and couldn't bear to say: "This is too risky, he Li Yi has a tyrannical personality, and he is famous for killing innocents indiscriminately." Feng Aiqing, you ......"

Feng Deyi's eyes were red, and he said righteously: "Your Majesty, the minister is old, and now it is the autumn of the country's peril, for the sake of the Tang Dynasty and for the great affairs of His Majesty, what can I spare for the minister's life?" ”

Li Shimin was moved by Feng Deyi's bold words, he slowly walked down the jade steps, walked to Feng Deyi, held Feng Deyi's hand and said: "Feng Aiqing, the old city seeks the country, the wind knows the grass, and the Bandang knows the loyal ministers, and he is talking about people like Feng Aiqing." I will give you permission to ride my Lightning Pony and escort you all the way with twenty of my personal guards. ”

Feng Deyi's eyes were red, and he bowed respectfully to Li Shimin and said, "Your Majesty, the minister is gone." ”

With that, he turned and left.

Li Shimin looked at the back of Feng Deyi leaving, and his mood couldn't calm down for a long time.

Feng Deyi, on the other hand, showed a subtle smile when no one was around, knowing that his plan had succeeded most of it.
