In the early morning, the mist has not yet dissipated.

The defenders on the city wall of Jinling suddenly became agitated.

"What is that?"

Then the dark army on the opposite side was seen parting, and dozens of war horses dragged the huge beasts slowly out of the formation.

A total of five cannons were placed in front of the team. Even though they were far away, the thick black gun barrels still made the defenders of Jinling City feel nervous.

There had been no movement for three consecutive days, but today five huge monsters appeared. The defenders on the city walls were startled and had a bad premonition.

"Quick! Go and inform the general!"

The deputy general guarding the city screamed loudly.

"Everyone prepare for battle!"

Suddenly, all the defenders on the city walls took action. Various supplies for defending the city were prepared, and the catapults were loaded with boulders. As long as the enemy came into range, they would throw the boulders out fiercely.

All the defenders were on high alert, waiting for the enemy's charge.

Pei Yun was standing at the front of the team at this time. Dozens of soldiers lifted the heavy cannons off the carriage and placed them on the ground.

"Adjust the angle and load solid bullets."

Following Pei Yun's voice, the specially trained artillery battalion soldiers quickly took action.

Clean the barrel, compact the gunpowder bag, put the iron gall into the chamber, and put the fuse in place.

"Cannon number one is ready!"

"Cannon No. 2 is ready!"

“…”

"Cannon number five is ready!"

Pei Yun looked towards Jinling City and said calmly, "Let it go!"

The fuse was immediately lit, and the soldier in charge of firing the cannon quickly covered his ears.

Bang bang bang!

The roar of the huge cannon was deafening, and the flames spewing from the muzzles tore the morning mist into pieces. The iron bullets tore through the air and smashed into the city walls with a shrill scream!

The defenders on the city wall were dumbfounded when they saw the cannonballs flying towards them. How could the enemy's range be so far? It was completely out of the range of the catapult.

“Get out of the way!”

The generals shouted loudly, but unfortunately the shell came too fast and when they saw it, it had already fallen.

"boom!"

A section of the city wall collapsed, and more than a dozen defenders were killed in the flying of bricks and stones.

“Bang! Bang!”

Two more shells hit the city gate tower, and the three-story arrow tower collapsed like a building block. The archers hiding inside fell down with screams.

The defenders were all dumbfounded. What kind of weapon was this? It was so powerful that it directly destroyed the city wall. You know, even throwing huge rocks could not destroy the city wall in one go.

"Adjust the angle, aim at the catapult on the city wall, and modify it to be an explosive bomb."

Pei Yun looked at the city wall with a telescope. The previous round of shooting was just a test of the power of the cannon, and it was not bad.

The only regret is that there are too few cannons. The craftsmen worked overtime but only managed to make four. Pei Yun didn't want to wait any longer and felt that five cannons would be enough.

The artillery battalion quickly switched to explosive bombs, and next to each cannon there was a soldier holding a telescope to observe the position of the catapults on the city wall.

"A little to the left, a little more to the left, a little higher, OK, this is the position."

The five cannons adjusted their muzzles under the command of the observers and soon opened fire again.

Five explosive bombs were fired, drawing a parabola and falling onto the city wall of Nanjing.

Boom!

The first shell accurately hit the catapult position on the west side of the tower.

The wooden catapult instantly disintegrated in the explosion, and the flying wood chips turned into deadly weapons, nailing dozens of operators around it to the city wall.

Soon after, other shells also fell towards the catapult. Although some shells had errors, they were still within the explosion range.

The flames swept across the area, the catapult was blown to pieces, and a second round of artillery bombardment followed.

The defenders on the city wall were completely helpless and could only watch the catapults being destroyed. They felt so distressed that they wanted to vomit blood. What kind of horrible weapon was this?

Not only does it have a long range, it will also explode, and what's even more terrifying is its accuracy.

This is to completely destroy their catapults.

"Aim at the city gate!"

Pei Yun gave the order again, and immediately the black cannon muzzle was aimed at the city gate.

…

The Imperial Palace.

Xiao Yu was still asleep. Pei Yun hadn't attacked for three days, which made him relax a little. He wondered if Pei Yun was going to lay siege.

After all, with an army of 500,000 and the people in Jinling City, the daily food and fodder expenses are huge.

But Xiao Yu was not in a hurry. After knowing that Pei Yun had rebelled, he made full preparations and collected grain from other states.

Moreover, the garrisons from other states came to support and brought food and fodder, so there would be no problem in sustaining the army for a year or two.

His city consumed a lot of food and grass, and Pei Yun's army of hundreds of thousands also consumed a lot of food and grass.

Then they would see who could hold out longer. Only when the border troops in the rear arrived, he would open the city gate to meet the enemy, attacking from both sides, and he would definitely beat Pei Yun to a pulp.

For this reason, he indulged himself last night and played with several concubines until very late.

This morning, before he woke up, he heard a faint roar. He didn't pay much attention to it until Eunuch Li ran in.

"Your Majesty, something bad has happened! Something terrible has happened!"

Xiao Yu sat up and asked, "Why are you so flustered?"

"Pei Yun has begun attacking the city wall."

Xiao Yu suddenly lost all sleepiness. He quickly put on his clothes and hurried out. As soon as he left the palace, he heard a deafening sound.

He was startled and rushed to the city wall with his imperial guards.

"What's going on now?" he asked loudly.

"Your Majesty, Pei Yun used magic. All our catapults were destroyed, and the city gate was also destroyed."

A general replied hurriedly.

"What?"

Xiao Yu was shocked. The city gate was destroyed?

"What are their casualties?"

The general's face was grim. "No one was hurt."

Xiao Yu was stunned. "How did they destroy the city gate without hurting anyone?"

To destroy the city gate, they must use a battering ram to hit the city gate, which means they must get close to the city wall. As long as they get close enough, they can attack the archers, so how is it possible that no one on the other side will survive?

"Your Majesty, you should read it yourself."

The general didn't know what to say. He didn't know what a cannon was and didn't know what kind of weapon it was.

Xiao Yu climbed up the city wall under the protection of a group of palace masters, and saw five huge black monsters in front of the enemy's army.

Boom boom boom!

There was a flash of fire and a deafening sound, and five cannonballs were seen coming towards the city wall, one of which happened to be Xiao Yu's position.

"Your Majesty, be careful!"

Someone among the masters of the palace shouted, and the top-notch master beside Xiao Yu quickly pulled Xiao Yu away. A second-rate master roared and slapped the flying shells with both palms.

Bang!

The shell exploded, and the second-rate master screamed as his body was shattered into pieces.

Xiao Yu felt a little cold all over. What a terrible weapon! He was a second-rate master, but he was completely destroyed. Even a second-rate master could deal with the huge stone of the catapult, but now he was blown to death by the black iron ball which was not as big as the stone.

The other palace masters also changed their expressions and quickly protected Xiao Yu down from the city wall.
