The technological level of black gunpowder is really not high, and it is not even as high as the fuse.

There are many charcoals with one tin and two yellow and three charcoals on the Internet. The difference is nothing more than purification and removal of impurities.

This time, Wang Xiao prepared more than 20,000 kilograms of black gunpowder for the royal city of the Goguryeo.

That's ten tons!

Even if the power is insufficient, the ten tons of this thing rings under the city wall, and the Goguryeo royal city cannot withstand it.

There is no problem in getting the city wall, the problem is how to transport things under the city wall.

This royal city has a moat.

Wang Xiao was not in a hurry. He first asked Li Shiji to arrest people, and arrested many Goguryeo people around him to cut off the moat water source brought from the Datong River.

Then a new canal was opened from the edge of the diversion canal to lure away all the water from the moat.

Then, the Goguryeo people were organized to carry cloth bags filled with soil to fill the river.

This is the royal city of Goguryeo, and the surrounding area is densely populated and very prosperous.

Although many people fled into the city, a large number of people still fell outside.

The Tang army had no intention of pity for these cannon fodders. They directly forced them to fill the moat under the rain of arrows from the defenders.

During this period, the defenders also left the city to launch counterattacks, and even had night attacks.

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

After paying a large number of Goguryeo's lives, a moat outside the royal city was finally filled with.

The nervous defenders were waiting for the Tang army to attack the city. But what puzzled them was that there were not thousands of troops coming from the Tang army, but instead a huge rushing car came out.

At least in their opinion, this is a rushing car.

Six or seven feet long, more than two feet high. There are wheels on the bottom, and thick iron plates covered with cowhide and fire-proofing.

The selected Tang army warriors pushed this special rusher slowly towards the city wall.

Although I don’t know what the Tang army is playing, the defenders are very responsible.

From crossbows to tinder oil, from rolling wood to rocks, all kinds of things rumbled on the ceiling, and it seemed that they would collapse at any time.

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

Tang Jun, who was hiding under the rushing car, lit a long fuse according to previous training. Then, like rabbits who were caught in arrows, they fled quickly to the Tang Army formation with huge shields on their backs.

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

Although I don’t know why they did this, the bad feeling enveloped everyone.

Then, the earthquake occurred.

The power brought by the ten tons of black gunpowder detonation was trembling.

The sound of thunder is even more thunderous, the smoke and fire that soars into the sky, and various debris flying all over the sky and even falling into the Tang army formation in the distance.

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

Even if it was far away enough, the Tang army was in chaos. Many people were beaten to the head by the splashed pieces.

It took a lot of energy to calm down the Tang army.

The well-trained Tang army was like this at such a distance, let alone the defenders directly at the core.

When the pungent smoke was blown away by the wind, the previous section of the city wall had completely collapsed, as if it was bitten by an unknown monster.

"What are you waiting for? Go." Wang Xiao looked at Li Shiji who was completely stunned. "Wait a little later, the reinforcements in the city will come to block the gap."

Wang Xiao said this a bit too much. The Goguryeo people in the city were completely scared at this time. No one could have thought about the support gap yet. After all, they didn't know what was going on now.

Li Shiji, who came to his senses, drew out his sword and roared, "Get in!"

The Tang army rushed up like a tide, crossing the collapsed city walls and pouring into the city.

The defenders lost the protection of the city walls and fell into huge chaos due to the explosion. Faced with the surging Tang army, even their will to resist was very low.

Wang Xiao did not act with the brigade, but went straight to the palace of Goguryeo alone. He was going to capture Gao Jianwu.

The city is now in a huge panic because of the previous loud noise.

Wang Xiao walked along the way and saw all the scattered defenders. Some of these people were frightened, while others simply took off their armor and threw away their swords and weapons, and hid directly into their houses.

Compared with the Tang Dynasty, this city is not big. Wang Xiao came to the palace without much effort.

The gate of the palace was closed, and there were some guards who were protruding their heads on the top of the city.

Wang Xiao, who was wearing only light armor, jumped up to the top of 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 officials were urgently discussing where the thunderous sound came from.

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

"Who is coming?" Seeing Wang Xiao, who was wearing Tang army armor, walking in with a knife in one hand, this was the first reaction of most people.

But there was a young man who was different. He didn't speak, but pulled out his hands and rushed up.

After one encounter, the two of them fought each other for more than ten consecutive times.

The young man took two steps back in surprise and asked, "Who is coming?"

He is a well-known warrior in Goguryeo and is known to be able to use six swords at the same time.

But before fighting with Wang Xiao, he was forced back by Wang Xiao with one-handed swords. This is the first time he has encountered such a powerful opponent.

"The sword technique is good." Wang Xiao threw a sword flower. "Are you the Quan Gai Suwen of the six swords?"

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

Wang Xiao drew out another knife with his backhand, and he also had both swords in his hands, "The person who sent you on the road."

This time, Wang Xiao took the initiative to attack, and he danced out white light from his swords, which directly covered Quan Gai Suwen.

In just a moment, Wang Xiao stopped his knife and stopped.

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

"Where are 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 tip, which is really disappointing."

Thinking back to the great hero who was described as being shot blind to Li Er's eyes and was able to chase the world's hero all the way to Chang'an City, Wang Xiao couldn't help but smile.

Quan Gai Suwen can no longer reply, he has already set out on the road and can never look back.

Many guards rushed up shouting and then fell under Wang Xiao's knife.

In Wang Xiao's eyes, the threat of these guards is far inferior to those sergeants on the battlefield who know how to form formations and cooperate.

He rushed up so stupidly, and was completely delivering food to Wang Xiao.

Wang Xiao stepped forward and walked step by step towards Gao Jianwu on the chair.

Looking at his clothes, where he sat, and the guards surrounding him, you will know that this person must be Gao Jianwu.

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

It's over, everything is over.

Goguryeo, which had lasted for hundreds of years, was eventually destroyed in his hands. This gave him the face to meet the ancestors and ancestors under the sacred springs.

The cold chill around the neck made Gao Jianwu open his eyes.

Wang Xiao smiled and looked at him, "Surrender, or lose his head?"

The young Gao Jianwu shed tears and asked with sobs, "I want to know who the great hero who captured me is."

Wang Xiao's smile became brighter and brighter, "Duke of Changle County, Tang Dynasty, Wang Xiao."

------

The Goguryeo royal city fell, and all the senior officials, including their Wang Gao Jianwu, were unable to escape.

When the news came out, Li Shimin, who was overjoyed, took a boat to the Goguryeo Royal City in person despite everyone's persuasion.

The envoy went out with the Tang army.

The cities in Goguryeo either received letters from envoys to surrender or were directly captured and destroyed by the Tang army, and had no other choice.

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

He invited Gao Jianwu to visit Chang'an City, and Gao Jianwu was also very happy to accept the invitation.

Li Er, who felt that he was invincible, easily defeated Baekje, who was frightened like a quail.

Later, Li Er rewarded meritorious officials, and all the soldiers sent troops were rewarded, and all the generals and civil officials were promoted. Wang Xiao was also promoted from county duke to county duke.

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

Satisfied Li Er took Gao Jianwu and the so-called king from Baekje back to Chang'an City.

Wang Xiao stayed to help Li Shijie recover from the aftermath.

After this, it was only in the early autumn of the sixth year of Zhenguan that it was completely settled here.

Li Shiji became the archer of the Anton Protectorate's Mansion and was busy with countless affairs.
