There was a boom in the explosion of gunpowder.

Black smoke billowed from the city of Buyeo, and after the Goguryeo soldiers defending the city suffered a number of casualties, Yu Zheng hid in the earthen fort at the head of the city.

Li Chengqian saw Goguryeo's reaction below, and secretly said that there was really a way to resist, if the Tang army thought that it had suppressed the Goguryeo people in the city at this time, it would definitely be met with a fierce counterattack when it sent troops to the city.

Li Chengqian thought of this, and a smile appeared on his face.

Because the Khitan and Xi tribes were under the command of their respective leaders and chieftains, the 3,000 people who went first had already carried the ladder and held shovels in a neat procession towards the earthen wall of Buyeo City.

Seeing this scene, Yuan Gai Suwen in the bunker at the head of the city also smiled, and he smiled very happily.

In the end, he looked up to the sky and laughed.

Hahahaha......

In the end, Yuan Gai Suwen laughed out of tears before stopping, wiping the corners of his eyes while smiling and saying to the generals around him: "I said that Li Chengqian's Huangkou child is brave and resourceless, and he is greedy for merit, but I didn't expect him to be unkind and unjust." ”

"Exactly, the tribal soldiers he drove charged him into battle, and he didn't even give him a decent weapon, and he wanted to attack the city one by one with farm tools?" A general next to Yuangai Suwen also followed.

Seeing the Khitan and Xi soldiers walking in a neat line, Yuangai Suwen became relaxed.

calmly ordered: "Pass my general order, and later the Khitan and Xi soldiers will attack and kill me fiercely, until they are afraid, and return to charge Li Chengqian's army." ”

When a general named Wu Bo heard this, he hurriedly said: "Great pair of Lu, if you kill them, the last general is ready to lead his troops out of the city to rush and kill Li Chengqian." ”

Several other generals nodded when they heard this, and Yuangai Suwen looked at the clan soldiers who were getting closer and closer, and finally nodded and said, "You go down and prepare now!" ”

Just when Yuangai Suwen regarded Li Chengqian as worthless, the Khitan and Xi Qingzhuang both arrived at the edge of Haogou under the city, and because of the air suppression, the city did not launch any attack on them.

So they calmly laid the ladder flat on the ditch, and then some of the people went to the city wall, took out their tools, and began to dig the black earth city wall with shovel after shovel.

One person looks small in front of the tall and majestic city walls, but thousands of people work together, and it's different.

They quickly dug the wall into the hollow, and the earth behind them was poured into the ditch by the people behind them, and the whole process was smooth and not wasted at all.

"How can you use such a stupid method, Li Chengqian, are you a pig?"

Looking at the tribal army calmly digging the wall, Yuangai Suwen finally went crazy.

He ran out of the bunker in despair, ignoring the golden crown on his head, and ran to the edge of the city wall with his hair disheveled, shouting below without any image.

"Li Chengqian, you idiot, you have the ability to directly attack the city."

"Father, don't be impulsive!"

His second son, Yuan Nanjian, ran out after him.

Bang!

Boom –

An explosive bag fell from the sky and exploded not far from them, knocking the father and son to the ground.

Yuangai Suwen regained some of his senses and was pulled back to the bunker by his son.

But when he thought of the black soil city he had worked so hard to build, he was not even afraid of gunpowder, and he was going to be dug down by these tribal soldiers in the most primitive way, and he trembled with anger.

Li Chengqian stood in front of the car and watched the Goguryeo army in the city never react, and then gradually reassured.

Yuangai Suwen has not seen it yet, now because there are grassland green and strong digging walls under the city wall, the explosives thrown in the air are all thrown into the partial city, if the Goguryeo army comes out at this time to stand on the edge of the city wall and drop arrows, it will definitely cause great trouble below.

However, Yuangai Suwen saw that his black earth wall was dug up, and he was already crazy, where could he still notice these details.

At the same time, Xue Rengui personally led a group of men and horses to keep an eye on the south gate of Buyeo City, preventing the Goguryeo army in the city from suddenly rushing out to attack and kill the tribal soldiers.

Standing in the bunker at the head of the city, Yuan Gai Suwen gradually calmed down, and watched the soldiers of the grassland tribe under the city digging the wall of the city where he leaned as an artifact, and a surging anger rushed from everyone's chests to their heads.

Yuangai Suwen forcibly suppressed his anger and didn't let it burn his head, gritted his teeth and ordered: "Pass my general order and order Wu Bo to lead five thousand cavalry out of the west gate and go straight to Li Chengqian's main formation. ”

The generals of the bunker were all excited when they saw that Yuangai Suwen had regained his senses and gave the battle order, believing that Yuangai Suwen's intelligence was not inferior to that of any Tang people outside the city, but they were only spoiled by the treachery of the Tang people.

Yuan Gai Suwen's second son, Yuan Nanjian, excitedly went to give the order in person, and as soon as he walked to the door, he heard Yuan Gai Suwen say coldly: "Tell Wu Bo that his task is to force Xue Rengui to come back, and if he does it, don't come back." ”

"Yes!"

Yuan Nanjian turned around and saluted excitedly.

The generals of Yuan Nanjian and Jiebaoli thought that Yuan Gai Suwen was ready to fight to the death with the Tang people, and they all had the intention of serving the country with their bodies.

However, Yuangai Suwen soon issued a new order, ordering his third son, Yuan, to stand by behind the south gate with 10,000 foot soldiers, and if Wu Bo could really get Xue Rengui to come to his aid, he would go out of the city and kill the grassland tribesmen who were digging my city wall.

If Wu Bo couldn't get Xue Rengui to come back to help, he would block the Tang army that had attacked the first earthen wall.

After the order was given, Yuangai Suwen took his second son and a group of generals to retreat into the second earthen wall.

-----------------------

Outside the city, Li Chengqian stood on the car and looked into the distance, watching the young men on the grassland digging deeper and deeper, and the cave could accommodate all the young men digging the wall, so he didn't have to worry about the Goguryeo army putting golden soup or feather arrows from the city, so he was relieved.

Turning his head and smiling, he said to the cave brother and Su Zhi next to him: "The first earthen wall is about to be breached, I don't know what way to deal with Yuangai Suwen?"

Brother Gu took the lead in patting his ass when he heard this: "Although Nayuan Gai Suwen is also a masterpiece, but when he meets a wise man like His Royal Highness the Prince, I am afraid that the six gods have been frightened and have no master, what else can he do?"

As he spoke, he laughed, and everyone laughed too.

Brother Cave sighed again: "It's a pity that Yuan Gai Suwen is rampant and stupid, knowing that His Royal Highness the Crown Prince will neither escape into the mountains and forests nor surrender and beg for his life when he arrives in Jinshan City, and even send a messenger to provoke in front of His Royal Highness the Prince, it's really ridiculous!." ”

Su Zhi also followed: "If the old man is Yuangai Su Wen knows that His Royal Highness the Crown Prince has arrived in Jinshan City, he should tie himself up, and then knock from Buyeo City to Jinshan City step by step to ask for mercy and beg His Royal Highness the Crown Prince for mercy and leniency." ”

At this moment, Shangguan Yi interjected lightly: "His Royal Highness the Crown Prince is shining thousands of miles, where can he escape?"

Li Chengqian understood but didn't say anything, and Brother Cave also reacted and hurriedly said: "Exactly, in today's world, it is only right for ministers to bow in front of His Royal Highness the Prince." ”

When Li Chengqian heard this, he diverted the topic and said: "Even so, you must also be careful, there are more than 100,000 people, the so-called trapped beasts are still fighting, and who knows what crazy moves they will make when they die." ”

Saying that, Li Chengqian's expression was straight and he said to Cheng Wuting: "You have to be careful and vigilant. ”

"The last will obey."

Cheng Wuting received the order immediately.

Brother Cave and Su Zhi pouted in their hearts when they heard this: Victory is in sight, and they pretend to be serious.

Li Chengqian's sentence was originally a benefit without expense, and he didn't expect him to play a big role.

It didn't take long for the rumbling of horses' hooves to be heard from the west, apparently an enemy attacking.

Brother Cave and Su Zhi looked at Li Chengqian in disbelief when they heard the voice.
