The scientific and technological level of black powder is really not high, and it is not even as high as the ignition rope.

One nitrate, two yellow, three charcoal, the specific proportion of the network is more. The difference is nothing more than purification and removal of impurities.

Wang Xiao prepared more than 20,000 catties of black powder for the royal city of the Goguryeo people this time.

That's ten tons!

Even if the power is insufficient, ten tons of this thing rings under the city wall, and the royal city of the Goguryeo people can't bear it.

It's okay to get the walls, the problem is how to get things under the walls.

This royal city has a moat.

Wang Xiao was not in a hurry, and first asked Li Shiyun to arrest people, and arrested many surrounding Goguryeo people to cut off the source of the moat water from the Datong River.

The next step was to build a new canal from the side of the aqueduct to divert all the water from the moat.

After that, the Goguryeo people were organized to carry cloth bags full of dirt to fill the river.

This is the royal city of Goguryeo, and it is very prosperous with dense people around the city.

Although many people fled into the city, a large number of people were still left behind.

For these cannon fodder, the Tang Army did not have the slightest pity. Directly forced them to fill the moat in the rain of arrows from the defenders.

During this time, the defenders also went out of the city to launch counterattacks, and even night raids.

But the Goguryeo soldiers could not defeat the Tang army, and after leaving thousands of corpses, no one left the city.

After paying the lives of a large number of Goguryeo people, a moat was finally filled up outside the royal city.

The nervous defenders awaited the siege of the Don army. But what made them puzzled was that instead of thousands of troops coming from the Tang Army, a huge rushing car came out.

At least in their opinion, this is the rush.

Six or seven zhang long, more than two zhang high. The bottom is a wheel, and the top is a thick iron plate covered with cowhide and fireproofing.

The selected warriors of the Tang Army pushed this special rushing car and slowly approached the city wall.

Although it is not clear what tricks the Tang army is playing, the defenders are very conscientious.

From bed crossbows to fire oil, from rolling logs to stones. All sorts of things rumbled against the ceiling, and it looked as if it was going to collapse at any moment.

However, the final result was that the car came to the city wall smoothly.

The Tang army, who was hiding under the rushing car, lit a long rope of fire according to the previous training. Then, like the rabbits that had been hit by the arrows, they hurriedly fled towards the Tang army with huge shields on their backs.

The defenders on the city wall looked at the Tang army in the distance suspiciously, raising their hands to cover their ears and opening their mouths.

I don't know why they did it, but the bad feeling hangs over everyone.

Then, there was an earthquake.

The earth trembled with the power of the detonation of ten tons of black powder.

The sound of thunder was more terrifying than thunder, the smoke and fire that rushed to the sky, and all kinds of debris flying in the sky and even falling into the Tang army's formation in the distance.

All of this makes it feel like the end of the world.

Even if it is far enough away, there is chaos on the Tang Army's side. There were also many people who were hit on the head by the flying debris and broke their blood.

It took a lot of effort to stabilize the Tang army.

The well-trained Don army did this at such a distance, not to mention the defenders directly at the core.

By the time the pungent smoke was blown away by the wind, the previous section of the city wall had completely collapsed. It's like being bitten down by an unknown monster.

"What are you waiting for, come on." Wang Xiao looked at Li Shiyun, who was already completely dumbfounded, "Wait a little longer, the reinforcements in the city will come to plug the gap." ”

Wang Xiao's words are a bit excessive. The Goguryeo people in the city were completely frightened at this time. There is a gap in support or something, I guess no one has thought about it for the time being. After all, now they don't even know what's going on.

Li Shixian, who came back to his senses, directly pulled out his saber and roared, "Kill it!" ”

The Tang army swarmed up like a tidal wave, pouring over the crumbling walls into the city.

The defenders lost the protection of the walls and were thrown into great confusion by the explosion. In the face of the surging Tang army, even the will to resist was very low.

Wang Xiao did not follow the brigade, but went straight to the palace of Goguryeo alone. He went to arrest Gao Jianwu.

The city was now in a great panic because of the loud bang that had been there before.

Wang Xiao walked along the way, and all he saw were the lost and depressed defenders. Some of these people were frightened, and some simply took off their armor and threw away their swords, and hid directly in private houses.

This city is not big compared to the Tang Dynasty. Wang Xiao didn't spend much effort to come to the palace.

The gates of the palace were closed, and there were some probing defenders at the top of the city.

Wang Xiao, who was only wearing light armor, jumped up to the city, kicked away a few stupid defenders and entered the palace.

In the main hall of the Goguryeo royal palace, a group of civil and military officers were urgently deliberating where the thunderous noise before came from.

Then, several palace guards smashed the gate and flew in.

"Who's coming?" Seeing Wang Xiao, who was holding a knife in one hand and wearing Tang Army armor, walked in, this was the first reaction of most people.

However, there was a young man who was different, he did not speak, but directly pulled out his two-handed knife and rushed forward.

With a face-to-face effort, the two of them confronted each other more than ten times in succession.

The young man took two steps back in disbelief and asked

The sentence "Who is coming?" ”

He was a well-known warrior in Goguryeo and claimed to be able to wield six swords at the same time.

But when he fought against Wang Xiao before, he was forced to retreat by Wang Xiao's one-handed knife with two knives in his hands. It was the first time he had encountered such a powerful opponent.

"The knife is good." Wang Xiao shook off the knife flower: "Are you the spring cover Suwen of six knives?" ”

"It's me." Quan Gai Suwen nodded, and glanced at the guards who were rushing in behind Wang Xiao, "Who are you?" ”

Wang Xiao pulled out another knife with his backhand, the same double knife in hand, "The person who sent you on the road." ”

This time, Wang Xiao took the initiative to attack, and the double knives were danced with white light by him, directly covering Quangai Suwen.

It was just a moment of effort, and Wang Xiao put away the knife and stopped.

As for Quan Gai Suwen, he looked at the dense wounds on his body in disbelief, and then collapsed to the ground.

"Where's your six knives?" Wang Xiao shook his head regretfully, "I thought you were a real master." I didn't expect it to be a silver-like wax gun head, which is really disappointing. ”

Recalling that this guy was described as a heroic hero who shot Li Er's eyes blind and could chase all the way to Chang'an City, Wang Xiao couldn't help laughing.

Quangai Suwen couldn't talk back, he was already on the road and couldn't turn back.

Many guards shouted and pounced, and then fell under Wang Xiao's knife one after another.

In Wang Xiao's eyes, the threat of these guards was far inferior to those sergeants on the battlefield who knew how to cooperate in formation.

pounced so stupidly, it was completely to deliver food to Wang Xiao.

Wang Xiao stepped forward and walked towards Gao Jianwu as a chair step by step.

Looking at his clothes, where he sits, and the guards surrounding him, he knew that this person must be Gao Jianwu.

Seeing Wang Xiao walking over as if walking, the strong guards in the past were chopped to the ground as if they were chopping melons and vegetables, Gao Jianwu closed his eyes in pain.

It's over, it's all over.

Goguryeo, which lasted for hundreds of years, was finally destroyed by his hands. How did this give him the face to meet the ancestors and ancestors under the Nine Springs.

The cold chill on his neck made Gao Jianwu open his eyes.

Wang Xiao looked at him with a smile, "Surrender, or lose your head?" ”

The young Gao Jianwu shed tears, choked up and asked, "This king wants to know, who is the big hero who captured this king." ”

Wang Xiao's smile became brighter and brighter, "Tang Changle County Prince, Wang Xiao." ”

The royal city of Goguryeo fell, and none of the high-ranking people, including their king Gao Jianwu, could escape.

When the news came out, Li Shimin, who was overjoyed, ignored the persuasion of everyone and personally took a boat to the Goguryeo royal city.

The envoys were dispatched together with the Don army.

The cities of Goguryeo either surrendered by the messenger's letter, or were directly captured and destroyed by the Tang army, and there was no other choice.

Li Er met Gao Jianwu, and the two chatted for a while.

He invited Gao Jianwu to Chang'an City as a guest, and Gao Jianwu was very happy to accept the invitation.

Li Er, who felt invincible, casually calmed Baekje, who was scared like a quail.

After that, Li Er rewarded the meritorious heroes, the sergeants who sent the troops were rewarded, and the generals and ministers were all promoted. Wang Xiao was also promoted from the county prince to the county duke.

Li Er also promised that when he returned to Chang'an City, he would definitely help find the Lanting Collection.

The satisfied Li Er took Gao Jianwu and the king of Baekje back to Chang'an City.

Wang Xiao stayed behind to help Li Shiyun deal with the aftermath.

This aftermath was good until the early autumn of the sixth year of Zhenguan, and it was considered to have completely settled down here.

Li Shichang became the protector of the Andong Metropolitan Protectorate and was busy with countless affairs.

And Wang Xiao is basking in the sun with a leisurely face.

Li Er was frightened by his strong strength, and didn't dare to let him go back to Chang'an City, so he was exiled and let him stay here.

Wang Xiao didn't care about this, he felt that his task was almost over.

The October sun shines on your body and makes you feel lazy.

Wang Xiao, who was lying in the rocking chair, stretched out his hand to block the sun, squinting at the sunlight spilling through his fingers.

The maidservants of Silla stood quietly and waited, and no one dared to disturb him.

Wang Xiao enjoys this kind of time when he is not working, and his favorite thing to do every day is to lie down in the sun and then play cards all night with those carefully selected Silla maids.

Originally, he planned to spend this day like this, but Li Shiyun's arrival disrupted his good deeds.

"What? You asked me to capture the king of the Silla people? ”

In the study room of the manor, Wang Xiao was not excited when he heard Li Shiyun's words, but he didn't understand what he meant. You must know that Silla is now an ally of the Tang Dynasty, or a vassal state.

"In the spring of this year, Li Jing broke through Tuguhun. Hou Junji also entered the Western Regions. There are tribes on the steppe who write to call His Majesty the Heavenly Khan. His Majesty was so pleased that he wanted to hold a feast for the captured lords of the nations to dance and give gifts. ”

Wang Xiao thought about it and understood Li Shichang's plan, "You mean, Goguryeo and Baekje are finished, then Silla is useless, it is better to directly merge into the Tang Dynasty." It just so happens that now the old king of Silla is dead, and the new king has just been established. Capture the new king and throw it into chaos, and then you go to clean up the pieces? ”

"That's right." Li Shiyun slapped his thigh, "That's what it means." Are you going to do this? ”

Wang Xiao laughed: "Of course." ”
