After escaping back to Pyongyang City, Yeon Gaesumun immediately supported Gao Jianwu's nephew Gaozang as the new king.
After that, they would sweep the land into soldiers, crazily recruiting the men, women, and children of Goguryeo, and at the same time rob them of all their food and property.
When spring came, there was no intention of doing spring plowing. After all, even Goguryeo was gone after losing, so why bother doing spring plowing?
Through almost crazy oppression and plunder, Yeon Gaesumun assembled an army of hundreds of thousands of people in a short period of time.
At the same time, enough food and military supplies were gathered to supply these so-called armies for several months.
Yeon Gaesumun also knew that the Tang army had a secret weapon called gunpowder. This thing was not too secret. After all, Goguryeo also had fireworks.
It's a pity that we don't have time now, otherwise Yeon Gaesumun will definitely research the secret of this thing like crazy.
He knew that even Anshi City could not withstand a strong defense, and Pyongyang City certainly could not withstand it.
Therefore, he distributed his troops and horses on the mountains along the way from Yalu River to Pyongyang City.
These were stationed on mountains, in narrow valleys, and in simple pass cities.
Yeon Gaeso-moon gave simple orders to the defenders behind each line of defense: kill whoever comes over.
As the Tang army crossed the Yalu River and headed south, they encountered obstacles at almost every hill and every mountain road. The men, women, and children who came over threw stones, wood, dirt, and anything else they could find from the mountains.
These Goguryeo people caused even greater trouble than their regular army.
Li Jing suggested to Li Er that he should take the waterway to cross the sea to Pyongyang City.
If you take the water route, you can avoid the rolling mountains in the north and land directly on the west coast plain to head towards Huanglong.
But this seemingly correct suggestion was rejected by Li Er without hesitation.
The reason for his refusal was simple: he came to destroy the country.
Simply capturing Pyongyang City is not a complete success. In the hundreds of years of history of Goguryeo, the capital has been captured many times, but Goguryeo has always been able to struggle to survive.
Li Er knew very well that if he wanted to destroy Goguryeo, he had to arrange for the disposal of all the people on this land, otherwise it would be useless even if he occupied the entire territory of Goguryeo.
Historically, after Li Zhi conquered Goguryeo, he moved all the local people to the Central Plains, thus destroying his country and giving him no chance to recover.
Li Er's plan was similar, but his methods were more drastic.
The Tang army began to fight for it one hill at a time and one mountain road at a time.
They got off their horses, put on their armor, held weapons and shields, and climbed up the hill step by step.
He used his armor and shield to resist the stones thrown down, dodge the thick rolling logs, and climbed hard using his hands and feet until he rushed into the formation of the Goguryeo people and killed them all.
Some Goguryeo people resisted fiercely and often fought to the last man.
Some Goguryeo people were afraid and would turn around and run away when they couldn't bear it any longer.
Each Tang army took turns to go into battle, fighting each other to break through the Goguryeo defense line.
When the fighting begins, Yuchi Jingde, Xue Wanche, Xue Rengui and others will even rush into the battle in person.
Yeon Gaesooun used the terrain advantages to the extreme and also used the human resources to the extreme.
While causing considerable losses to the Tang army and lengthening the time limit of the Tang army's attack, Goguryeo's population was also losing at a very high rate.
The time has come to May, and Goguryeo has missed this year's spring plowing. Even if the Tang army withdraws its troops now, Goguryeo will inevitably suffer from famine after the autumn harvest, and most of the people in Goguryeo will starve to death.
But Li Er didn't care about the losses of the Tang army at all, and still arranged for each department to attack one after another.
By the end of May, the Tang army, which was stuck in a vicious battle, finally broke through the mountain defense line and approached Pyongyang City.
Countless fightings along the way, how many Goguryeo people were wiped out, even the Tang army could not count.
After all, according to the military regulations of the Tang Army, civilians did not count military exploits.
As early as after learning the news of Gao Jianwu's death in battle, Yeon Gaesumun had already made up his final determination.
Even Gao Jianwu was able to die for Goguryeo, and Yeon Gaesumun naturally had this consciousness as well.
In the past few months, no expense was spared in people's and material resources to construct the entire city of Pyongyang and its surrounding areas into a fortress full of spikes.
The last strength of Goguryeo was concentrated near Pyongyang City.
Hundreds of thousands of soldiers and civilians blocked the inner and outer areas of Pyongyang.
After the Tang army besieged the city, they began to attack the city.
First, the strongholds around Pyongyang City were removed one by one, and then the defenses outside the city were eradicated.
Fighting went back and forth between the two sides, and countless corpses were thrown into the ditch.
Jin Gui's war horses were treated as livestock that could be abandoned at any time, and they were tied with ropes and dragged the antlers and wooden stakes against the rain of arrows.
The strong men of the Tang Army wielded hammers and smashed the sheep and horses walls layer by layer.
Every time you make progress, you will pay a heavy price.
After all, the armor of the Tang army could not cope with the pits that suddenly appeared at their feet, nor could it withstand the kerosene thrown by the Goguryeo people, nor could it block the crossbows fired from the city wall, etc.
The most exaggerated incident was when the Tang army was fighting fiercely with the defenders in a trench. The Goguryeo people, who had planned for a long time, directly filled the entire trench with a depth of ten feet and drowned themselves and the Tang army.
It can be said that the Goguryeo people tried every possible method they could think of.
Facing the constant losses of the Tang army, Li Er remained as unmoved as a piece of wood. He just kept sending sergeants up to clear the defense facilities outside the city.
A commander at his level has already been mentally prepared for losses on the battlefield.
When he was the emperor, he cherished the people under his command because everyone had to pay taxes to him.
But on the battlefield, the soldiers are just numbers to win the war.
After the Tang army suffered thousands of losses, they finally opened a passage to the city.
Under the crazy shouts and attacks of the defenders at the top of the city, a large shield car wrapped in three layers of thick iron sheets was pushed toward the city wall little by little under the gaze of countless pairs of eyes.
The defenders tried their best to resist with various weapons, and the crossbows fired fiercely, making a dull sound when they landed on the shield cart, but unfortunately they could not penetrate.
The stones thrown by the trebuchet hit the ceiling and smashed the stones, but they still couldn't penetrate.
As the shield car got closer and closer to the city wall, the defenders who gradually went crazy even sent out death squads, desperately trying to stop the shield car.
Then the covering troops of the Tang Army would fight to the death to block it. Amidst the brutal killing, the shield car finally approached the city wall.
As the dead soldiers pushing the shield cart fled frantically, the defenders on the top of the city also began to flee.
However, Goguryeo's brave warriors rushed under the shield car with all their lives, but the fuse had already burned into the thick wall, and they did not even know how to put it out.
Many brave warriors pushed the shield cart desperately, trying to push the shield cart away from the city wall.
But the hoe of the shield cart has been lowered, and its weight is extremely heavy, so it can be easily pushed away.
With the sound of a thunderbolt from the blue, all the efforts of the defenders were wiped out.
The soldiers of the Tang Army rushed into the city, but were surprised to find that the city had been transformed into a war fortress.
The intersections were sealed, the courtyard walls were reinforced, and there were traps and trenches everywhere on the ground. Countless Goguryeo people were hiding in them carrying various weapons, farm tools, and even wooden guns.
For this kind of situation, Li Er only had one order, and that was to fight!
Li Yunze is building a temporary dock on the shore not far from Pyongyang, and the logistics transportation line will be mainly used for shipping.
Li Er's envoy found him and asked him how to best attack in this complex environment.
"You brought so much gunpowder here, you can't transport it back again, right?"
Li Yunze said slowly, "Don't take the streets, just use gunpowder to clear the way and blow up the walls and houses along the way. When you encounter a place that cannot be conquered, just use gunpowder to blow it up. After capturing so many prisoners, they arranged to fill ditches and bury pits for transportation."
Earth. Use all the strength in your hands. This will
There is nothing to save at this time.”
After giving his opinion, Li Yunze no longer paid attention to the fighting in the city, and was not even willing to go there. He just arranged logistics on the coast and did his own job.
It wasn't until more than half a month later that Li Yunze, who was taking a nap, was awakened by the cheers outside.
Only after I came out did I know that the Tang army had finally captured Pyongyang City.
“Have you caught Yeon Gae So-moon?”
"He committed suicide. He killed his family and the king of Goguryeo first, and then committed suicide himself."
Li Yunze breathed a long sigh of relief, the battle was finally over.
There are no decent opponents around Datang, and there is no need for him to do any more logistics.
Baekje had been destroyed by the troops of Su Dingfang and Xue Rengui before Goguryeo. Li Er redivided the four counties recovered in the Han Dynasty into prefectures.
Then the people from Goguryeo and Baekje from various places migrated to Central China, and then migrated and immigrated from Central China.
It was busy until the autumn harvest, when the army began to return in batches.
Li Yunze, who was in charge of the logistics, waited until winter before returning to Lijiazhuang.
Back home, Princess Changle and Wu Meiniang each held their children to greet her.
"Will there be another war in the future?"
"There will definitely continue to be wars." Li Yunze teased the child, stretching his arms to hug him on the left and right. "But I won't go again. I will stay at home with you from now on."
The Tang army's foreign wars did not stop. In addition to the long-term war with Tubo that consumed its national power, the main targets were the two rivers and the vast prairie in the northwest.
In the 20th year of Zhenguan, King Wu Li Ke came out of the distant black land of Ukraine.
In the twenty-third year of Zhenguan, Li Yun, the king of Chiang Kai-shek, went out to control Lianghe.
In the 29th year of Zhenguan, Li Zhen, the king of Yue, came out to conquer Tianzhu.
In the thirty-fourth year of Zhenguan, Li Shen, the king of Ji, came out to control Persia.
Zhenguan
With the blessing of the medical skills of Li Yunze and Sun Simiao, he did not fall into the trap of seeking immortality in his later years and took indiscriminately those elixirs containing a large amount of heavy metals.
Li Er avoided dying at the age of fifty and lived for a long time.
It was not until the forty-seventh year of Zhenguan that Li Er, who was more than seventy years old, finally fell seriously ill and lay on the bed to meet with the important ministers to arrange his funeral.
"You are indeed one of the gods."
Li Er, who had arranged for Minister Gu Ming, met alone with Li Yunze, who had lived in seclusion for many years.
Looking at his face that had hardly changed over the years, Li Er forced out a smile, "Can I seek immortality?"
Li Yunze shook his head calmly, "You are not a fool, so you cannot live forever."
The light in Li Er's eyes full of expectation obviously dimmed.
After a long silence, Li Er asked again, "Will you stay to assist the prince?"
"Your Majesty has personally taught the prince for thirty years, and he no longer needs my assistance."
Li Er sighed lightly, "I'm so lucky to have Zihou to help me. It's so lucky for Tang Dynasty to have Zihou to help me~~~"
Looking at Li Er, whose expression was rapidly declining, Li Yunze raised his hands in salute and bowed deeply.
"Your Majesty, have a safe journey."
In the forty-seventh year of Zhenguan, Emperor Li Shimin of the Tang Dynasty, who conquered the world's largest territory and conquered the world's largest territory, died of illness in the Hanfeng Palace. He was later buried in the Zhaoling Mausoleum with Empress Changsun who had lived there many years ago.
The new emperor Li Zhi ascended the throne, and was given the posthumous title Emperor Da Guangxiao, the Great Sage of Civil and Military Affairs, and the temple name Emperor Taizong Wen.
Logically speaking, it should be Emperor Wu's, but in Li Zhi's opinion, Wen is better than Wu.
The Tang Dynasty entered the Li rule era, and all the old officials of Zhenguan had gradually withered away.
After sending Li Er to Zhaoling, Li Yunze returned to Lijiazhuang and never left home.
When Princess Changle and Wu Meiniang died, Li Yunze, who was revered as the Living God of the Tang Dynasty, disappeared without a trace after arranging Wu Meiniang's funeral.
In the world of the Tang Dynasty, only his legends and stories remained from then on.
