In the Gongsun Mansion in Goguryi City, tonight is destined to be a sleepless night.

At this time, Gongsun Chen was discussing with Gongsun Du, and Gongsun Chen said, "I regret not listening to Du'er's words, and now I have caused such a catastrophe, how to deal with it"?

Gongsun Du thought for a while and replied, "Now we can only strictly guard the city, and wait for the troops to retreat when the food of the Guanhai Department is exhausted."

After hearing this, Gongsun Chen asked anxiously, "Isn't there any other way for Du'er?"

Gongsun Du replied, "Yes, yes, but my father will not choose."

Gongsun Chen asked, "Du'er, let's talk about it, now that you have such a field, what else can't you choose."

Gongsun Du replied, "Please surrender when you go out of the city, maybe you can save your life."

Gongsun Chen said disappointedly, "Xuansu County is so unwilling!"

Gongsun Du said, "Father, don't worry, tomorrow I will defend the city."

"Okay, Du'er is here, why worry about not being able to protect Goguryi, Du'er is also tired today, go back early to rest and prepare for tomorrow's war."

After Gongsun Chen finished speaking, he slowly walked back to the bedroom. Gongsun Du saw it in his eyes and sighed.

After Tian Feng and Guan Hai finished eating, they led the soldiers to besiege the city on all sides.

When Gongsun Chen and others heard that the Han army outside the city was besieging the city, they immediately came to the city wall.

After Guan Hai saw that he was surrounded on all sides, he stepped forward and shouted, "Gongsun Chen, as a Han Chen, you colluded with foreign races to block the arrival of heavenly soldiers, and now you are besieging the city on all sides, you should come out and surrender quickly, Uncle Ben is happy for a while, and may leave you with all your corpses."

Gongsun Chen trembled angrily on the city wall and shouted loudly. "If you want me to go out of the city and surrender, don't dream of your Spring and Autumn Festival, the archers will shoot him to death, whoever shoots him to death, I will reward ten acres of fertile land and a thousand stones of grain"!

When the archers in the city heard this, they all wanted to shoot out with one hand desperately, and the rest of the soldiers looked at the archers with envy.

Guan Hai was scolding, and suddenly saw the arrows raining down on the city, and immediately waved the weapon in his hand to shoot down the bow and arrow, and retreated to a safe place.

Guan Hai retreated out of the range of the archers and shouted angrily, "Soldiers, scold me together, Gongsun Chen'er is blessed by heaven, but he doesn't think about how to serve the country, he will only collude with the people of different races, what is the face of such disloyal and unfilial people in the world."

Gongsun Chen watched Guan Hai lead the troops under the city to insult, and felt that the sky was dark, and a mouthful of blood spurted out.

Gongsun Du next to him immediately held him up and said, "Father, it's okay, Guan Hai will only be strong-tongued, don't worry about your father."

Gongsun Chen took a deep breath and said calmly for a while, "Du'er, I'm old, if I can defend it this time, Xuansu County will be handed over to you."

Gongsun Du replied, "Father, rest assured, the city of Goguryi is here, my Gongsun Du is here, and if the city is broken, people will die."

After Gongsun Du finished speaking, he asked the soldiers to send Gongsun Chen back to rest, and then ordered to hold on.

Guan Hai scolded under the city for a long time, and saw that there was no response from the city, so he said, "Everyone is divided into three teams, and I will take turns to scold until the turtle with a shrunken head comes out."

At this time, Guan Hai was tired of scolding, and was about to go back to the back to rest, when he saw Tian Feng coming from afar, he immediately greeted him and said, "Sir, you see that my scolding is so ugly, but the city just can't come out, you see what a good plan there is."

Tian Feng smiled and said, "General Guan has worked hard, I'll put on a good show for you."

After Tian Feng finished speaking, he led two hundred archers to the city, and then ordered the soldiers to tie the strips of cloth he had written on to the arrows and shoot them into the city.

When Gongsun Du saw the archers shooting arrows, he immediately shouted, "Give me the shield on top, and the rest of the people be careful to avoid the bow and arrows."

Gongsun Du dodged for a while, and then found that something was wrong, the bow and arrow shot from the city had no arrows at all, so he picked up one and looked at it, and then untied the strip of cloth on it, and after reading it, his face changed greatly and shouted, "Collect all the arrows that shoot at the city for me, and not a single one can flow out."

Tian Feng saw that the defenders in the city were collecting arrows, and said to Guan Hai with a slight smile, "General Guan, please send the remaining strips of cloth to the gates, and then shoot them into the city."

Guan Hai asked, "What is this, sir, and what's the use of shooting into the city?"

Tian Feng replied, "This is Gongsun Chen's life talisman, and in less than three days, someone will open the city gate and offer Gongsun Chen's head."

Guan Hai said, "Sir, it's really fake, I don't believe that a small strip of cloth has such a big ability"!

Tian Feng glanced at Guan Hai and said, "Then let's make a bet, do you dare?"

Guan Hai replied, "What don't you dare to do, sir, you just say what to bet on"!

Tian Feng said, "Okay, then bet that you won't drink for a month, do you dare to bet"?

Guan Hai thought for a while and said, "What is there to dare to do, then what reward do I have for winning."

Tian Feng replied, "After the clean-up is completed, let you drink"

Guan Hai said, "Okay, a word is a certainty."

When Gongsun Du heard the soldiers report that all the gates of the city had received strips of cloth shot in, his face was completely bloody, and after a long time, he said, "The order will go down, the whole city will curfew, and if there is a violation, they will be killed on the spot."

At night, Gongsun Du came to Gongsun Chen's room, and Gongsun Chen asked, "Du'er, how is the war during the day?"

Gongsun Du replied, "Father, Guan Hai didn't attack the city during the day, just ......"!

Looking at Gongsun Du's appearance of wanting to speak and stopping, Gongsun Chen said, "Du'er, don't worry, I still have something I can't let go of now, say it"!

Gongsun Du sighed and said, "Guan Hai ordered people to shoot cloth strips into the city, saying that as long as the thief head is killed and the city gate is opened, the rest of the people will not be held accountable, otherwise the city will be broken, and no matter the old or young chickens and dogs will be left."

After listening to it, Gongsun Chen became much older, and after a long time, he said, "Du'er go down first, I'm tired."

Early the next morning, Tian Feng ordered Guan Hai to lead people to feint and attack the city, and the city wall of Goguryi was short, and Guan Hai was in danger under several attacks.

Gongsun Du desperately defended the city, and finally Guan Hai couldn't stop after several rounds of siege, and chose to withdraw his troops and return to the camp.

Guan Hai returned to the camp and said angrily, "Sir sees that I am about to attack, why doesn't Sir let me attack with my life?"

Tian Feng laughed and said, "Even if General Guan captures the city, the battle of the trapped beasts will suffer heavy losses, and the general is assured that someone will open the city gate tonight to welcome us into the city."

At this time, the two great families in Goguryi City were gathering together.

The head of the Zhang family said, "Guan Hai outside the city has made a fate, and now Gongsun Chen is not far from death, can we accompany him to die, what good way do you have?"

The head of the Zhao family said, "This is reasonable, we can't sit still." I have a nephew who is a lieutenant under Gongsun Chen, and he will be on duty to guard the south gate tonight, and then he can open the city gate to welcome Guan Hai into the city, and then I can gather soldiers to surround Gongsun Chen's mansion, what do you think?"

The head of the Zhang family said, "Okay, let's do it, I will gather the soldiers to besiege the mansion, and you will send someone to inform Guan Hai and welcome them into the city."

The head of the Zhao family replied, "Okay, without further ado, I'll go now."

Tian Feng was inspecting the camp at this time, and when he heard that his soldiers came to report that someone in the city had voted, Tian Feng smiled and said, "Goguryi City is already in the bag."

Tian Feng returned to the camp and saw Guan Hai saying, "Where are the people in the city"?

Guan Hai took out a letter and replied, "I have arranged to go down to rest, this is the letter he handed me over."

After reading it, Tian Feng said, "General Guan go down and prepare, and enter the city tonight."

From time to time, Guan Hai led the people in the city to wait at the south gate, and after a while, he saw the south gate blazing into the sky, and Guan Hai shouted, "Soldiers, take the city at this moment, everyone rush me"!

Guan Hai led the troops to rampage all the way, and when they met the rebels, they were all killed on the spot, and after occupying the south gate, they sent people to capture the other three gates, and led their troops straight to the county guard.

Gongsun Du had just finished patrolling at this time, and before he fell asleep when he got home, he heard the shouts of killing, and immediately put on his armor and went to the city wall.

Gongsun Du met a soldier who had been defeated all the way on the road, stepped forward and grabbed one of them and asked, "What's the matter?"

The man replied, "The general is not good, Zhao Tu has opened the south gate to welcome Guan Hai outside the city into the city, and now Guan Hai is attacking the other three gates."

After hearing this, Gongsun Du immediately gathered the remnants of the soldiers around him and walked to the county government, and when he arrived in front of the county government, he happened to meet Guan Hai leading the troops, and the two armies fought together.

Gongsun Du found that his headquarters had no intention of fighting at all, so he could only sigh and lead the remnants of the soldiers to the north gate.

Before Guan Hai came to the county guard's mansion, the head of the Zhang family immediately stepped forward and said, "Gongsun Chen has been surrounded by our group, please give the general an order to attack the mansion."

Guan Hai glanced at it and said, "Give it to me, whoever kills Gongsun Chen, will be rewarded with ten gold"!

Guan Hai invaded the mansion and found Gongsun Chen, he had already committed suicide by poisoning.

Guan Hai glanced at it and said, "Come on, cut off the head of this thief, and hang the city tower for three days to set an example."

After Guan Hai finished speaking, he sent people out of the city to welcome Tian Feng into the city, and led his troops to clear the remnants of the resistance.

After this battle, the remaining families under Li Huiyi sent their clansmen to serve as officials under Li Huiyi as a sign of loyalty.
