After confirming that Li Chengqian was personally on the expedition, Li Shiji and Su Dingyi went on the road first with the supplies they needed.

Su Dingfang sailed from Tianjin to Xiongjin Fortress in the former Baekje Kingdom, and when he launched a general attack, he would lead his army to attack Pyongyang from the south.

Historically, the Tang Navy was based on Wendeng, Shandong, and Xue Wanche led the army to attack from the sea.

Now that Xue Wanche had been killed, and Li Chengqian had developed Tianjin, he ordered Ren Yaxiang and Hao Chujun to lead the army to attack from Tianjin.

Li Shiji went to Anshi City first, where he blocked the rescue troops that Pyongyang might send.

Li Chengqian personally led the five major armies to Jinshan City, and Xue Rengui was leading the Eighth Tang Army to confront Fuyu City, which was personally garrisoned by Yuangai Suwen.

Before Li Chengqian left Yandu City, he heard that Brother Li Xiang had left Chang'an, which made him feel a lot more relieved, but Li Chengqian himself was not very sure about giving Li Ju drug rehabilitation.

First, there is no medicine for later generations, and secondly, Li Ju is too young, and he has laid the root of his illness in Chang'an in recent years, and if he is forcibly detoxified, it is very likely that he will die.

Thinking of that well-behaved child, Li Chengqian felt heartache, he didn't dare to tell the crown princess Su about this.

Thinking of this, Li Chengqian sighed, shook his head and said secretly: Put these things aside for a while, the main purpose now is to establish supreme military authority on the battlefield in Liaodong, and then go back to Chang'an City to settle the account!

He has the military prestige to destroy Goguryeo, and he can return to Chang'an without taboos.

Li Shimin still has great prestige in the army, although Li Shimin has cultivated immortals and sought Taoism over the years, but with the efforts of Li Chengqian and Ma Zhou, there has been no mistake in major national affairs, and Li Shimin is still a wise monarch in the eyes of outsiders.

What can he do if he wants to be on the throne?

Many people think that as long as they learn from the changes of Xuanwumen, they can ascend to the throne.

But don't forget that Li Shimin was not only a prince himself, but also a highly decorated founding general, and he was one of the main founders of the Tang Dynasty.

Not only did the Qin Prince's Mansion have a large number of civil ministers and military generals who were bent on supporting him, but even other ministers were not willing to follow Li Yuan after Li Jiancheng's death.

But what about Li Chengqian, he is the crown prince, everything was given by Li Shimin, and his creation of Li Shimin is unpopular.

Then Li Shimin is not Li Yuan, even if Li Chengqian controls Li Shimin, some ministers will have illusions about Li Shimin.

By helping Li Shimin to restore the throne, he achieved the goal of becoming a supreme minister.

Therefore, Li Chengqian extremely needs to destroy the great merit of Goguryeo, and use such a great feats to deter the world, so as to have a deterrent effect, if he does something in Chang'an, even if there are ministers with other thoughts, he will not dare to move lightly.

Li Chengqian went on an eastward expedition this time, the civil officials only brought Shangguan Yi, and the military generals only Liang Jianfang and Cheng Wuting, Cheng Wuting was responsible for Li Chengqian's safety on the road, and Liang Jianfang was responsible for the daily military affairs of the army.

In this way, Li Chengqian came to Jinshan City all the way safe and sound.

Historically, the Tang Dynasty attacked here more than ten years later, when Yuangai Suwen was already dead, and it was the son of Yuangai Suwen who guarded Fuyu City, but now he is Yuangai Suwen himself.

When Xue Rengui heard that Li Chengqian had arrived, he hurriedly set up a position and went out of the city to greet him in person.

He already knew that something had happened in Chang'an City, and he understood that Li Chengqian had to come out this time. In order to give Li Chengqian Liwei, the scene was very grand.

Li Chengqian's side also set up a full set of crown prince honor guards early, and the brilliant crown prince's honor guard was followed by tens of thousands of troops.

Facing the overwhelming momentum, the generals behind Xue Rengui didn't even dare to raise their heads.

Xue Rengui saw Li Chengqian, who was dressed in gold armor, riding a tall war horse and walking slowly, and hurriedly led his generals to dismount and salute.

"Ministers, see His Royal Highness the Prince!"

Although the armor is still a heavy salute of kneeling on one knee, no one thinks of anything at all: the armor is not suitable for full salute.

"All the generals are flat!"

Li Chengqian rode on the horse and said lightly.

"His Royal Highness Prince Xie!" Xue Rengui led the generals to make a promise.

Looking at the eyes of the people behind him, he immediately felt that Li Chengqian was even more sacred and tall, and the awe of Li Chengqian in his heart deepened a little.

Li Chengqian led all the way to the Tang army camp in Jinshan City under Xue Rengui's leadership, and directly entered the Chinese army's big tent.

Li Chengqian sat down in the big tent, and Cheng Wuting led dozens of thousands of oxen with helmets in reserve, and stood on both sides of the throne with their hands pressed on the hilt of their swords.

Liang Jianfang, Xue Rengui and others led their generals to salute Li Chengqian again, and then they lined up on both sides.

Li Chengqian looked at the soldiers in front of him with a serious expression, until all the generals lowered their eyelids under his majestic gaze, and then said in a very majestic tone: "You fought very well last year, and established a great contribution to the destruction of Goguryeo by the Tang Dynasty this year, and King Gu will not forget your merits."

This time, the lone king came in person just to destroy Goguryeo in one go, and I hope that you will go back and train the soldiers strictly, and prepare to break through Buyeo City first before the battle. ”

"Obey!" When the generals heard this, their spirits were lifted.

"Good! Everyone, step back first, the lonely king brought good wine and meat from Yandu, as well as a new play for the East Palace, and the whole city will take turns to drink and feast and watch the play today and tomorrow. ”

"His Royal Highness Prince Xie, the last general will retire."

After the ordinary soldiers retreated, Li Chengqian looked at Xue Rengui, after several years of training, Xue Rengui was already a famous general in the Tang Army.

And everyone knows that Xue Rengui is Li Chengqian's sworn friend, and as long as Li Chengqian does not fall, he will have a bright future.

"Rengui, the Lone King has brought 50,000 elite soldiers and countless gunpowder supplies, can you break through Buyeo City in one battle?"

Hearing this, Xue Rengui looked at Li Chengqian's expression and said with some hesitation: "Goguryeo has been fighting with the Tang Dynasty for several years, and has already figured out some ways to deal with gunpowder. ”

"What can they do?"

Li Chengqian immediately asked.

Xue Rengui was relieved to see that Li Chengqian was not in a hurry to give an order, and hurriedly reported to Li Chengqian:

"Buyeo Fortress is the northernmost city of Goguryeo on the west bank of the Yalu River, and it is also the only city on the west bank of the Yalu River that still controls Goryeo Sentence.

This city was personally led by Yuangai Suwen, and when they found out that our army's gunpowder was strong, they piled up three thick earthen walls outside the Buyeo city wall, so that our gunpowder could not blow through their walls.

The houses in the city were torn down, and the people lived in holes dug in the ground. Even if we send hot air balloons to bomb from the sky, it won't be of much use.

Now there are 100,000 soldiers and horses in Buyeo City, and there are only 8,000 soldiers and horses here, plus the five soldiers and horses brought by His Royal Highness the Prince, it is difficult to win in a battle when the gunpowder advantage cannot be brought into play. ”

"His Royal Highness the Prince, in this way, we can only transfer several other armies to encircle Fuyu City." Wang Fangjian put forward his own suggestions.

Li Chengqian thought for a while, shook his head and said: "You can't transfer other armies to encircle it, Li Shiji and they are guarding Anshi to prevent Pyongyang from rushing to help." ”

There is another point that Li Chengqian did not say, if the army of several roads was encircled and fought hard with Goguryeo, the battle damage would inevitably be serious, and although the result was victorious, it would not be good for him to move back to the court.

Li Chengqian looked at Xue Rengui again and said, "You go and explore again, and draw a detailed map of the terrain around Fuyu City." ”

"Obey!"

The generals looked up and saw that Li Chengqian did not say anything more, so they withdrew from the big tent and returned to their tent.

"His Royal Highness the Crown Prince, what now?"

As soon as the generals withdrew, Cheng Wuting couldn't wait to ask.

Five years have passed, Cheng Wuting is already a tall and sturdy young leader, a few years ago Li Chengqian was in Yandu, he and Wang Fangyi took turns to come to the battlefield in Liaodong to make meritorious contributions.

Although he is still by Li Chengqian's side, his position is already that of a four-rank lieutenant general.

Li Chengqian took a deep breath and said: "If you feel that there is no way to do something, then go to investigate and study, go more, ask more questions, understand this matter clearly, and find a solution." ”

Cheng Wuting thought about it for a long time before he said in a daze: "What His Royal Highness the Crown Prince means is 'know yourself and know your opponent, and you will not be defeated in a hundred battles.'" ’?”

Li Chengqian nodded and said: "Yes and no, 'know yourself and know your opponent, and you will not be defeated in a hundred battles' to add one to 'know astronomy at the top, and know the geography at the bottom.'" ’

Now the Goguryeo army in Buyeo City can't defeat the Tang Dynasty, so they will besiege the city with earth, if we use the lives of the army to fill it, it will be too stupid to kick them and pile up the earthen wall, and we must not do this unless we have to. ”

Cheng Wuting understood Li Chengqian's intentions after hearing this, and said: "Then tomorrow, I will also go to Fuyu City to have a look." ”

Li Chengqian nodded and said, "The Lonely King will go with you." ”

Without waiting for Cheng Wuting to speak, he got up and turned to the back account.

Cheng Wuting stood in the big tent and his face shrunk into a bitter melon.
