The entire Jingnan Mansion took action.

To stay alive.

The eldest prince recalled the garrisons of the surrounding county towns and states.

He wasn't going to ask for any of these places.

I can't hold it.

Subsequently, the eldest prince launched an emergency mobilization order to mobilize young and strong to organize the army.

In the beginning, the resistance of the people was high.

But after killing a few people, the rest of them were trembling, and they could only watch as they were captured.

In just one day and one night, the strength of Jingnan Mansion reached 50,000.

There is still a lot of grain and grass in the city, although the ordnance is simple, and there is little rattan armor, but it does not affect the defense of the city.

The boulder rolling wood used to defend the city was also well prepared.

Everyone knows that the ratio of casualties between the attacking and defending sides in siege warfare is exaggerated.

No matter how awesome the Han army is, it is impossible to break through Jingnan Mansion in the short term.

Day 3.

The mighty army finally arrived at Jingnan Mansion.

It would have only taken a day and a half to arrive.

It's just because the state cities and counties along the way are empty, as long as you waste a little time, let the soldiers of the Nanling King take over.

This is also the plan of the Great Prince.

It is used as a delaying tactic and has plenty of time to prepare.

For three days, Ma Yuanfeng and Pei Guangqing did not receive any response about surrender.

Therefore, when the army arrived, they first set up camp, and then sent people to shout.

It's a pity that the four gates of Jingnan Mansion were closed and there was no response.

Seeing this, Ma Yuanfeng did not rush to attack the city, but sent someone to give the eldest prince a three-day deadline.

If you don't respond within three days.

Then all responsibilities are at your own risk.

Unfortunately, there was still no response.

Jingnan Mansion, Royal Mansion.

"Your Highness, the Han people said that if we don't open the city gate within three days, we will bear the consequences..."

"Humph!" The eldest prince snorted coldly, "Do his blue sky daydream, let alone three days, our royal city is harder than the royal city of the king of Nanling, let alone three days, even if it is thirty days, they may not be able to attack it..."

According to intelligence, the enemy army numbered just over 20,000 people.

Originally, there were 30,000, and the more than 10,000 people of the king of Nanling had to occupy the county seat and the city of Zhou in various places along the road, and there were many fewer of them.

With more than 20,000 people, he wanted to take down his Jingnan Mansion.

It's tantamount to a fool's dream.

Not to mention that the casualty ratio of siege warfare can reach an astonishing 1:10.

"Tell the ministries to keep an eye on the Han army around the clock." The eldest prince continued to speak, "My second brother has already gone to the Nanyi countries to move rescue troops, as long as our neighbors send troops, they will fight us?" ”

"Your Highness is wise." The general Si Kou smiled slightly, and also agreed with these views.

The mountain of Jingnan Mansion is high and the emperor is far away.

They also share borders with the Nanyi States.

With more than 20,000 people outside the city, and 10,000 cavalry, it is impossible to take them.

The city has enough food, grass and water, enough for them to last for half a year.

The truth was as the eldest prince had expected.

Within three days, the Han people did not send anyone to shout, but spent the whole day in the camp.

This move made the soldiers defending the city more confident again.

But they don't know.

This time hundreds of sappers came.

The engineer is a new branch established by Guo Tianyi when he went north to quell the rebellion of the princes.

It can be used to build roads and bridges, and most of them are to make siege equipment.

On the fourth day, the sun had just risen.

And the army of black oppression went out of the camp and set up a battle.

The sound of thunder drums shook the sky.

When the army reached a distance of 500 steps from the east gate of Jingnan Province, it stopped advancing.

Subsequently, improvised catapults were pushed out.

The catapult "invented" by Guo Tianyi has a range of about 500 steps for a 60-pound stone projectile and a 200-pound stone projectile for about 200 steps.

At the time, it was the most advanced catapult in the world.

Originally, Daebong also had catapults.

However, the structure is bulky, it is not easy to repair after damage, and the distance of throwing stones is only half of what Guo Tianyi invented.

The current catapult with four rollers at the base.

It can be said to be the pinnacle of the late period of ancient China.

When they saw a dozen or so small-looking catapults parked five hundred paces away, the soldiers defending the city laughed.

This kind of thing, from such a distance, can shoot over?

Pity...

The smile on the face of the defender of the city froze in the next moment.

Sou~

Sou~

Sou~

Countless stones rose into the air, whistling and drawing a graceful arc in the air, smashing straight into the city wall.

In an instant, rubble was scattered, and countless people were killed.

Screams rang out.

Some of the hapless soldiers were just turned into mashed meat.

Boom boom boom~

Boom boom boom~

Dense stones were constantly slamming down on the gates and walls like cannonballs.

Where had these soldiers seen such a horrific scene?

"Run.."

"It's horrible, this..."

"Mom, I'm going home to Mom..."

"I don't want to die, I won't fight if I kill me..."

“......”

“......”

The soldiers on the city walls scattered before the first round of stone bombardment was over.

There are generals who want to stop it.

But no one listened.

This is the quality of a skirmisher as well as an improvised soldier.

It's simply a rabble.

With a "boom", the east gate of Jingnan Mansion was smashed open a huge gap.

Another round of bombing.

There is not a single ghost on the eastern city wall.

The east gate was also smashed into countless pieces.

Woo~

Woo~

The horn of Daebong's elite charge sounded.

Then the cavalry turned into a black torrent and entered the city.

The infantry also entered the city with the cavalry.

Fighting, without the slightest suspense.

The shield soldiers and heavy armor soldiers opened the way, and the cavalry rushed left and right in the city, and the soldiers in the city were already frightened.

When he saw Daebong's soldiers, he put down his arms and knelt on the ground and begged for mercy.

When the eldest prince learned the news, countless soldiers in black armor had already surrounded the palace.

"This..."

"This Nima..."

"Fake, right?"

"It's over, it's all over..."

The eldest prince sat on the throne and was dumbfounded.

He didn't know how the Han people had entered the city so quickly.

An hour later.

Ma Yuanfeng and the others entered the royal city.

The eldest prince died in battle.

It's also a man.

He knew that if he fell into the hands of the Han people, he would definitely have no way to live.

Killing one's own father is something that the Han people cannot tolerate.

The fact is that they simply do not understand the combat effectiveness of the Han army.

Not to mention a city like Gyeongnam.

Even the fortified cities in the Central Plains could not stop the bombing of catapults.

At the beginning, Guo Tianyi used a large catapult to break through the fortified city in only half a day.

Of course, with the current productivity, some black technologies cannot be made.

Otherwise, siege warfare will become much simpler.

"Has the second prince found it?"

Pei Guangqing checked the palace and found no trace of the second prince, so he looked at a brocade guard and asked.

"Lord Kaiyu."

"Based on our intelligence."

"The second prince should have escaped from the city a few days ago and went to the Nanyi Kingdoms."

"But at this moment, I should be on my way back..."

Hearing this, Pei Guangqing breathed a sigh of relief.

I can finally make a deal with Your Majesty.

King Nanling sat on the throne of Nanfeng Mansion, sighing, only feeling that everything was like a dream.

Celebration banquets are indispensable.

On the same day, a piece of good news was sent to the Forbidden City.
