It is naturally not easy to let Gogurye destroy the country. At least Goguryee has many elite soldiers and generals!

In fact, the destruction of Goguli in the Tang Dynasty was not something that could be done in one or two years, but lasted for more than ten or twenty years, and it was not until the Li Zhi period that the destruction of Goguli was done.

The great results can be achieved now are entirely because of the existence of artillery. If it weren't for this thing, Li Shimin would have to survive for a while.

In fact, after Anshi City was captured, the morale in Gogurye began to collapse.

Before the Tang Dynasty came, Gogurye was extremely arrogant under the leadership of Quan Gai Suwen.

In order to mock the soldiers of the Tang Dynasty, they even specially started Zhujingguan, and they were responsible for the national affairs, sent troops to attack Silla, and cut off the connection between Silla and the Tang Dynasty. They were ambitious. However, the battle in Anshicheng gave Quan Gai Suwen a heavy blow.

It is said that refugees who fled to Pyongyang described the battle in Anshicheng as if the sky had collapsed, which was extremely terrifying. They had never heard of such a war.

Not only is the case with Goguryu Liquan Gaisuwen, but also the case with Xueyantuo Khanate and Japanese pirates.

They did not expect that the soldiers of the Tang Dynasty were so fierce this time.

The battle continued to fight, and took a break in Anshicheng for a while. The army started again and rushed towards another important city, Bozhuo City.

It seemed that Quangai Suwen heard that the soldiers of the Tang Dynasty used magic to attack the city, so he attached great importance to it and immediately sent a large army to defend Bozhuo City.

Originally, Bozhuo City was built against the mountain, which was easy to defend but difficult to attack. In addition, Gogurye's heavy troops were extremely difficult to conquer, but under the cannon, it was still destroyed and countless Gogurye's soldiers abandoned the city and fled.

They were all scared.

In the next month, the soldiers of the Tang Dynasty pushed forward all the way, winning successively, capturing Bozhuo City and continuing to aim at Huangcheng and Yincheng.

It seemed that because the Tang Dynasty's offensive was too fierce, the morale of Goguli's army collapsed, so most of the Goguli people in Huangcheng and Yincheng abandoned the city and fled. Li Shimin and others, together with Huangcheng and Yincheng, conquered several small cities in succession, and the army directly pointed to Pyongyang.

Now, Gogurye is already scared.

The whole country was extremely shocked. They had no idea what the cannon was. They just felt that the soldiers of the Tang Dynasty seemed to be able to use thunder magic and no one dared to resist it.

Wherever they go, they are all defeated soldiers and generals!

Since occupying Anshicheng, Li Shimin and others have won great victories, killing more than 30,000 enemies, seized 50,000 war horses, 50,000 cattle, more than 10,000 iron armor, and a large number of other weapons.

Today, within hundreds of miles from Anshicheng to Pyongyang, there are almost no people.

However, after winning successes, I encountered a problem, that is, winter has arrived and the weather has gradually become colder.

Gaoguli Prime Minister Quan Gai Suwen and others had long anticipated this problem, so when they ran away, they burned a large amount of food and grass, so that Li Shimin had collected very limited food and grass over the past period of time.

And if winter comes, Li Shimin will face great trouble.

In fact, when they came here before, they had already considered this issue and prepared a lot of food and grass. However, Li Shimin and others had already entered Goguryeo. The front line was very long, so food and grass could no longer keep up.

Once winter comes, Gogurye's forage will disappear, heavy snow will block the mountains, and the food will not be supplied to everyone, not to mention that they have seized a large number of war horses and cattle.

Now, there is no people within a few hundred miles. The next big city is Pyongyang. At this time, all the people of Gogurye have shrunk into Pyongyang City, and there are more than 100,000 reinforcements sent by Baekje. It is extremely difficult to conquer Pyongyang.

Now the commander of Gogurye is Quan Gai Suwen, who is a hero of a generation. At first, he might have been caught off guard by the cannons of Li Shimin and Fang Jun. However, as time goes by, and the artillery ammunition is limited, Quan Gai Suwen still stabilizes his position.

Now, Pyongyang City is not panic because of this, and the fortifications of the city are in an orderly manner.

Li Shimin, Li Ji and others predict that if they want to conquer Pyongyang, it will probably take two or three months, and even adding artillery will be useless.

After siege, the artillery and ammunition have been exhausted. Even if you work hard, you can't do it so quickly.

At this time, Li Shimin was standing in a tent near the outside of Pyongyang City with a telescope, looking into the distance. When he saw that the walls of Pyongyang City were already full of soldiers, he couldn't help but take a deep breath.

"I didn't expect that this Quan Gai Suwen had such backbone! I wish I could break his bones!" Li Shimin said coldly: "Strengthening the walls and clearing the world? Who gave him the trick?"

"Your Majesty! It will probably snow in half a month. The soldiers will probably be extremely difficult at that time! Now, we lack things to keep the cold!" Li Ji said with a worried look on his face: "Liaodong has always been extremely cold. Without cold things, it is difficult for the soldiers to fight. What's more, the forage is missing!"

"When it comes to things that keep the cold, I remembered something!" Li Shimin turned to look at Fang Jun: "Fang Yiai, do you have something to keep the cold?"

Fang Jun was stunned, looked at Jinyang, stood up and nodded and said, "Weichen really has something. However, Weichen has obtained this thing for a relatively short time and is now harvesting it. It is extremely difficult to do it with rush work!"

"I heard about it a few days ago! But I didn't see the real thing, it was just someone who reported it!" Li Shimin smiled and said, "How many have you planted?"

"There are more than 100 acres, not many, and it is expected to be worn by three or five hundred people!" Fang Jun said: "But this thing is still being viewed. If it is effective, more will be planted next year!"

Li Shimin nodded: "Soon after harvesting, I will present some to me! I want to see what it is!"

When Jinyang heard this, he was also a little curious and asked, "Husband, what is the father talking about?"

Fang Jun glanced at her and said, "It's that cotton! It's already harvested in Youzhou, and after it is packed, you can make a cotton jacket! With this thing, it will be extremely easy to keep the cold in winter. It's not just freezing to death!"

"Ah?" Jin Yang was surprised.

"But at this time, we still have to withdraw back to Youzhou first! This battle cannot continue to fight!" Li Shimin looked at Pyongyang City again, sighed and said, "When next spring begins, I will definitely capture this city and kill Quan Gai Suwen's dog head!"

When Fang Jun, Li Ji and others heard this, they nodded quickly: "Yes!"

In fact, they had already won a great victory at this time. After all, they had already reached Pyongyang and Gogurye's royal city.

If Pyongyang is captured, Goguli will be destroyed. Now Goguli has stationed one million troops in Pyongyang, and there are also Baekje reinforcements. It will be very difficult to attack by relying solely on the 100,000 soldiers of the Tang Dynasty. If it is not done well, the entire army will be wiped out.

Therefore, retreat becomes the best choice.

At least we have to return to Youzhou to accumulate energy and wait until the snow melts next year.

In addition, artillery shells also need to be prepared. If they do it again, they may completely flatten Gogurye.

Jinyang and Xiaohe were a little happy when they began to withdraw their troops.

They don't like fighting and feel very restrained in the middle of the army.

Now that I am going to return to Youzhou, I am naturally extremely happy.

Of course, although he planned to withdraw his troops temporarily, Li Shimin did not give up the occupied land and set up an Andong Protectorate in Liaodong, leaving 10,000 troops and ten artillery in Anshi City to prevent Goguli from attacking sneak attacks.

And the Andong Protectorate is temporarily under the jurisdiction of Zhang Liang!
