"I will definitely come back!"

Twenty days after surrounding Yu Pass, the Khitan and the Tang Kingdom did not reach any agreement, but just chose to withdraw their troops in a tacit way, after the prisoners exchanged.

Yelu Xian rode on the horse, looked back repeatedly, and looked unconscious.

"Your Majesty, Tang is now in great power. As long as we accumulate strength, we will definitely come back next year."

Yelu Xiu Ge was equally indignant.

"It's hard!" Yelu Xianshi, the counselor on the side, waved his fan and shook his head and sighed: "The city pass is so dangerous, difficult, difficult, difficult-"

As a counselor who assisted Yelu Xian to seize the throne, Yelu Xianshi's words made the Khitan Khan even more melancholy.

Especially when he thought that Yan Yan, who had always been cute and charming, would be insulted and ravaged by the shameful, lustful and despicable Emperor of Tang, he was extremely sad.

Although the Khitans have never paid attention to the love between children and even regard them as weak, who can be like this with him, how much comfort is it to be with a girl when she is lonely?

The hatred of the country made Yelu Xian even more angry.

Finally, he stared at Yuguan and the military camps, and Yelu Xian said loudly: "There is a great shame, the country's hatred and the family are irreconcilable--"

"I will definitely avenge this revenge in the future--"

As he said that, Yelu Xian ran directly on his horse, with a fierce momentum, which scared the nobles.

Everyone thought that the Khan was very concerned about the loss of land, and couldn't help but show joy and care. This is much better than Yelu Jing, the sleeping king.

Only Yelu Xianshi understood the Khan's thoughts, and couldn't help but shake his head and said to the stunned Van Li: "Ni Li, follow me and be sure to protect the Khan's safety."

The Dragon Maid immediately responded, and was proficient in riding skills, and immediately chased after him.

Yelu Wuzhi looked at the far away of Khan and remained silent. His years of experience made him understand the truth of silence.

"Forget it!"

Yelu Wuzhi sighed and said, "Youyun is not the land we are waiting for. If you lose things and take them back, you will never have an eternal master in this land."

This sentence made the nobles much more excited. Although they lost some vitality, they would definitely be regained after cultivation.

Thinking of this, many people couldn't help but blame Yelu Jing. It was his indulgence in wine hunting and the continued turmoil in the country that allowed the Tang people to find an opportunity.

The dead are the best scapegoats.

To soothe people's hearts, Yelu Wuzhi has this prestige.

Hundreds of thousands of cavalry came in a mighty way, leaving behind the bodies of a land, and left in a few interest, leaving only horse manure, sheep balls, and even a trace of hay.

"Although the Khitans plundered a lot of wealth and plundered Youyun, the only ones who benefited were the nobles, and the lower class were still so poor!"

Li Jia was speechless. The mess all over the place was very terrifying, stretching for thousands of acres, and the road was really hard to walk.

However, the Khitans finally retreated, and he was still happy. After all, the Sixteen Prefectures of Youyun were taken back and were safe and sound.

After fulfilling the vision of the Han people for decades, his prestige has reached its peak with his merits in unifying the world.

Now, what is left is to repair Yuguan and compete with the Khitans for tribes of various ethnic groups on the grassland.

From then on, the place where the clouds descended south would no longer have to withstand war.

"If you don't lose your Youyun, you don't know how noble youyun is, if you don't fight the Khitan, you don't know how difficult it is!"

Li Jia held the female wall and couldn't help but sigh.

All the generals expressed their agreement and kept flattering. Although most of them were the same, Li Jia felt comfortable listening. There was no way, and everyone liked to listen to good things.

However, except for flattery, everyone was stretching their necks, hoping to hear the emperor's arrangements for the next one.

Youzhou is called Beidu and is also a front line close to the Khitan. It has frequent wars, so it is natural that it has to be properly arranged to guard the important generals.

Such an important task, regardless of the status, can fight against the Khitans alone, which represents a continuous stream of merits and wars, and is of great significance to promoting official positions and titles.

Obviously, Li Jia has also considered such a problem.

What is more reference is the nine sides of the Ming Dynasty, with the Great Wall as its edge and the nine guards as its points connected into one piece, thus having great defensive capabilities.

Not to mention that the Great Wall is useless, it is an offensive and defensive institution, much stronger than the French Maginot line of defense.

If Wu Sangui hadn't opened Shanhaiguan, the Qing Dynasty might not have been able to enter the pass. The Liaoxi Corridor and countless fortresses would be meat mills.

What the Northern Song Dynasty remembered was to contact the Great Wall and establish a line of defense.

"But the Great Wall is now in disrepair and difficult to defend!"

Li Jia sighed.

From the late Tang Dynasty to the present, in one or two hundred years, even the wind and sun were exposed, even the most solid project would be corrupted by the power of nature. Therefore, the Ming Dynasty simply threw away the Qin Great Wall and built one on it.

It is easy to distinguish between the Qin Great Wall and the Ming Dynasty.

The one with bricks and stones is the Ming Great Wall, and the one with rammed earth is the Qin Great Wall. Because of bricks and stone buildings, they were only popular during the Northern Song Dynasty.

Interesting knowledge has increased again.

"The northern defense line is full of loopholes!"

The emperor whispered: "The Great Wall has been disrepaired for so long, and many passes everywhere have been abandoned. It is not easy to defend the north!"

"According to Your Majesty's wishes, it needs to be overhauled?"

Li Huai said softly.

"That's right!"

Li Jia nodded and said, "First of all, move me eastward twenty miles, with mountains and seas behind me, and build a new Xiong Pass, which is at least four or five meters high and two meters high. It was okay in the past. The Khitans did not prepare this time. The next time they brought craftsmen, Yu Pass would be in danger!"

The generals nodded repeatedly, indicating that the emperor's clarification was that it would be better to rebuild this dilapidated Yu Pass than to cultivate it!

In fact, Yingzhou is still too close. If you move forward a little further and arrive in Jinzhou, it will be foolproof.

But Jinzhou is too close to Liaodong and close to Shangjing. The Khitans will never give up. They have a lot of manpower and material resources. It is different for long-distance raids like today.

"In addition to the new pass, we must move forward. Every thirty miles, we will build a military fortress, with thousands of troops stationed, and more than ten of them will be built in a row, according to the terrain."

As he said that, Li Jia smiled and said, "In this way, if he wants to pass Yu Pass, he has to chew down the cities. I see if the Khitans can withstand it."

Yanshan and Yinshan defense lines are the most solid, and the Great Wall was built because of it. The climate between the south and north of the mountain varies greatly.

"Guo Jin--"

"The last one will be here!"

"You have made great contributions to attacking several cities like this. You will be promoted to the deputy guard of Beidu, and also serve as the position of Beidu Defense Envoy, and stationed in Yuguan."
