The royal city of Goguryeo, located in the northeast of the Tang Dynasty, is known as the area of Liaodong. The cold winter here occupies almost half of the year, and with the help of this time advantage, the war between Goguryeo and the Central Plains Dynasty rarely suffers.

Even if the Qin soldiers endured hard fighting, they could not resist the might of heaven and earth, at least, in the face of the severe cold of Liaodong, they could not hold on.

This is also the reason why Goguryeo's ambitions are constantly expanding, and they believe that between the white mountains and black waters, the Central Plains people will not be able to defeat them.

Here, Goguryeo borders the Tang Dynasty in Liaodong City, and Xinshi City is like iron. Their Wang Cheng is located between the white mountains and black waters, and is called Ji'an, Huanren, and is also known as the mountain city of Wunu Mountain.

Here, Goguryeo served as the royal capital for hundreds of years, and the tombs of the kings and nobles are all over here. Even a millennium later, it has left its mark on the World Heritage List.

But now, this city, which is considered to be the most majestic city of Goguryeo, has welcomed an uninvited guest.

It's not appropriate enough to say that this is an uninvited guest, but it is directly a big demon king.

Lu Hanyang and the Goguryeo people had nothing to say, so they flew in the direction of the mainland on the red-crowned crane quilt, and then found the right direction on the land and came to the royal city of Goguryeo.

This city can be regarded as a high wall, the city is deep, with a wall of nearly five zhang, and a thickness of two zhang, and the Goryeo royal palace shines with gold in the sun.

This country is deeply influenced by the Central Plains Dynasty, and their imperial palace also has a strong style of the Central Plains Dynasty, with pavilions and pavilions that are somewhat similar to Chang'an City.

But Lu Hanyang didn't look at these things, he directly launched an attack on the city directly outside the city. A silver sword light fell from the sky and slashed directly towards the city wall.

In an instant, the city wall collapsed, and the collapse was stirred into powder by the sword qi. The city wall made of bluestones could not block the attack of the sword qi at all, and directly turned into a pile of flying ash, which dissipated in an instant.

When the smoke and dust rose up, the entire royal city of Goguryeo was enveloped in it, and all the people in the city felt suffocated. The thick dust made it difficult for them to breathe, and even suffocated to death.

"Listen, from now on, all the cities of Goguryeo are not allowed to build walls! If there is a next time, it will not be as simple as tearing down the walls that you are waiting for! Lu Hanyang originally wanted to force Goguryeo to surrender directly, but after thinking about it, forget it.

Without the enemy outside, then Datang will inevitably reduce the combat strength of the soldiers, and I don't know what kind of situation I will face in the future, Datang's strong soldiers are the most fundamental force to protect the Central Plains.

Because he himself must deal with those outsiders, and he can't free up his hands to take care of the battlefield of ordinary people, so the Tang army can't slack off in the slightest.

In this process, it is very necessary to leave a part of the enemy for the Tang army as their whetstone. Lu Hanyang believed that the enemy he faced would not have the ability to directly improve the combat effectiveness of the army.

It's like a golden wolf sacrifice, he summons a pack of wolves, and he can't make these wolves become more powerful beasts, they are still just ordinary wolves. And he also carried out massacres in the Turkic royal tents, apparently in search of food for his wolf pack.

As for why the Turkic royal family was not killed, there was obviously another purpose in it, but Lu Hanyang also knew that he would never know this secret.

In fact, it is very simple, the golden wolf sacrifice captures the Turkic royal clan and orders the steppe tribe to pay tribute to cattle and sheep, so that he can accept more wolves, and his strength can also increase faster.

The royal city of Goguryeo was shrouded in smoke and dust at this moment, just like the imperial capital 1,400 years later, full of haze. This kind of treatment that the people of the Celestial Empire can enjoy after a thousand years, at this time Lu Hanyang gave preferential treatment to the Goguryeo people.

Not to mention how many people were inhaled into the bronchial tubes by the dust, which led to various complications, not to mention those who were directly stuck to the respiratory tract on the spot and then suffocated to death, this directly scared all the nobles of Goguryeo.

When Lu Hanyang flew over, it was noon, the sun was blazing, and basically no one was walking outside. And after that, the smoke and dust are directly filled, and you can't see through the smoke and dust at all, how can you see people.

Therefore, it began to be rumored among the Goguryeo people that this was the anger of the gods, and the gods gave instructions that the Goguryeo royal city should not be able to build a city wall, otherwise the next time the earth would directly turn over and destroy the Goguryeo royal city.

This frightened all the Goguryeo authorities, and they couldn't figure out why the Goguryeo royal city was not allowed to build the city walls, how was this possible, and what to do if the enemy attacked? When there are no walls, the enemy will drive straight in.

And Gao Jianwu and several powerful ministers speculated an answer that was even more difficult for them to accept: this is not as simple as the city wall of Goguryeo City, and the Great Wall that is being built in the northwest.

Gao Jianwu's face was gloomy, his fists were clenched, he couldn't figure out who had such a great ability to directly make the four walls of the Goguryeo royal city directly turn into powder in a short period of time, and even the soldiers on the head of the city could not be spared, and there was not a single one alive.

And below, a heroic young man was the same, but his eyes flashed with a kind of pain.

"King, this is news from our spies from Datang!" The heroic young man took out a scroll and handed it to Gao Jianwu.

"Gai Suwen, what's the use of this information? I'm afraid that our plan to build the Great Wall will no longer be able to be implemented! When the time comes, the Datang army will drive straight in, what will our soldiers do to stop the iron hooves of the Datang? Gao Jianwu said.

"King, this is also what I want to tell the king, this time, I'm afraid it was really done by Datang!" The young warrior named Gai Suwen is the eldest son of the Yuan family, a great nobleman of Goguryeo, and the spokesperson of the Yuan family's interests in the court.

"What's the news from Datang?" Gao Jianwu asked.

"The spies we sent to the Datang border army, although the level is not high, but this matter is a very happy thing for them, and it is widely publicized in the Datang army, so it should be somewhat credible." Yuangai Suwen said.

"Really? Let this king see! "Gao Jianwu did not call himself me, because he was only the king of Goguryeo, not the emperor. It seems that it was only after the Tang Dynasty that Asian countries successively changed the name of the king to the emperor. For example, the emperor of the Wa Kingdom and the like.

"Datang has a Pure Yang Sword Immortal? What kind of god did this time? That's impossible! I, Goguryeo, am a nation blessed by the god of white mountains and black waters, how can there be no gods to stop this pure yang immortal? Gao Jianwu looked at the scroll, and his face turned pale.

He knew that this was probably true, otherwise how could he directly make the walls of the Goguryeo royal city turn into powder in an instant!
