"Prepare to shoot!" Ruan Youjin personally commanded the Ruan family army on the city wall to defend.

On the other side of the Zheng family's army, because Zheng Lord arrived at Changyulei to command the attack personally, the morale of their soldiers was high. After the bombardment of the artillery, thousands of soldiers of the Zheng family, led by their generals, tried to attack Changdeli to see if they could open a gap in the strong Changdeli.

On the city wall, the soldiers of the Ruan family stared nervously at the soldiers of the Zheng family who were getting closer and closer, and the flintlock guns in their hands were trembling. Last year, the Jiuzhou Army supported a batch of firearms from the Ruan family, but the Ruan family could not afford more firearms, and a considerable number of soldiers still used backward melee guns.

Bang! I don’t know which nervous soldier couldn’t help but fire the first shot. He rushed on the city walls and began to shoot in a mess below. The white smoke produced by gunpowder lingered on the city.

"Fire the cannon!" The cannons guarding the city wall also began to shell the Zheng family soldiers who were hitting Changdelei under the command of the cannon leader.

The soldiers of the Zheng family were not rushing towards the strong Changdeliuan in a noisy manner, but holding shovels in hand and digging trenches toward the Changdeliuan. This shoe trenches can greatly reduce the damage to them by muskets and cannons from the city walls, and are more useful than any sturdy armor of this era.

Ruan Youjin was helpless in the shooting caused by the soldiers' panic and the shelling behavior was also helpless. Although he emphasized during training that when he was really facing the enemy, someone would still make a mistake.

"General, our muskets and cannons have limited damage to them. If they were allowed to push the trench under our city wall, they would have many ways to collapse our city wall!" Ruan Youjin's personal soldiers braved the stray bullets and watched the battle situation below through the walls.

I saw a trench outside the Zheng family camp, approaching Changdeliui in a tortuous manner, and from time to time, soil was thrown to both sides of the trench. Although the artillery attacks of the cannons guarding the city caused considerable obstacles to the Zheng family soldiers who were digging the trench, the trench was still approaching.

"Do you think I didn't see it?" Ruan Youjin also didn't know how to deal with the Zheng family's improved tactics, because the one at a disadvantage is their Ruan family, and he rarely has a way to stop the Zheng family's attack. "But this time the Zheng family has indeed learned a lot and actually knows how to use digging trenches to approach our defense line, but we are useless."

"I have an idea, I don't know if it's feasible." A personal soldier rarely made a suggestion. "We can prepare gunpowder and tincture oil. If they dare to approach the city wall, we will throw tincture oil and gunpowder downwards and burn all the enemies below!"

"Your idea is OK, but after a long time, we may burn down our city walls." Ruan Youjin said.

"General, look, they have new moves!" Suddenly, the soldiers guarding the city shouted.

Ruan Youjin followed the direction pointed by the soldiers and found that in the opposite Zheng family's artillery position, there were more than a dozen giant elephants pulling several large chariots, and the large chariots were loaded with thick bronze cannons. The muzzles of these bronze cannons were far larger than ordinary field cannons, and they were even less than the cannons of Changdelei's city guarding. They also had to use huge power giant elephants to haul them!

"Such a huge artillery, is this a siege... a cannon?" Ruan Youjin finally changed color now. He could not have imagined that the Zheng family had the ability to create heavy siege artillery.

Although ordinary field cannons can also be used to siege cities, the efficiency of breaking cities is far less than that of special siege cannons. But how did the Zheng family create such a few heavy siege cannons?!

"It must be the Netherlands who supported them! I heard that the Netherlands and the Jiuzhou Army had a grudge. Both sides fought a war in Yizhou. In the end, the Netherlands were defeated. They have been supporting the Zheng family in recent years. If they hadn't transported these heavy artillery from the West to the Zheng family, how could the Zheng family produce such terrible heavy artillery with their own strength!" A military officer guarding the city next to him cursed, "Damn the Netherlands, they are always making trouble behind their backs!"

"The Netherlands? It seems that it is time to ask the Jiuzhou Army to teach them a lesson. Alas, if we had no choice, we would not want to ask the Jiuzhou Army for help unless we had no choice..." Ruan Youjin said, and he had no words to say, that is, once the Jiuzhou Army was requested to intervene in the war, according to the latest treaty they signed with the Jiuzhou Army, the Ruan family would have to bear five million taels of silver, and the huge debt and interest that would be repaid for twenty years was equivalent to the resident under the Ruan family who borrowed 10 taels of silver from the Jiuzhou Army. This is an amazing figure in Annan, not including the annual interest.

Boom!!! After the Zheng family's siege cannon was arranged, they began to launch violent shelling on the city wall! Although the siege cannon has serious problems such as heavy and insufficient killing efficiency, its damage to the city wall is far greater than that of any other firearm. A huge solid bullet hit the city wall hard, and each shell made the solid city wall whine, and the bricks and limestone fell off, and cracks like spider webs spread around!

"This power is the same as thunder!" The soldiers of the Ruan family at the top of the city were frightened by the siege cannon, and their bodies were tightly pressed against the wall.

"When do you think they will be able to use up their gunpowder..." A soldier hid behind the city wall and was talking to another soldier. The solid city wall he thought he was relying on suddenly burst, and scattered stones shot and killed the soldiers of the Ruan family around him!

This is a solid bullet used by a siege cannon that hit the wall!

With dozens of field cannons and several giant siege cannons, the Ruan family soldiers who were digging trenches to attack the Changdezui defense line were so stable that they kept approaching the Changdezui defense line...

The sound of the siege cannons fell into Ruan Youjin's ears, like a mountain collapse. As long as the Zheng family had sufficient ammunition, these cannons were enough to open a gap in the Changde Base defense line! Ruan Youjin felt like he was a dog and had not seen him for a year. Whether it was tactical consciousness or firearm equipment, his old opponent seemed to be on the same level.

"Go and ask the Regent to lead his troops to help us Changdeli, and ask the Nanyang Fleet to go north along the coast to attack Shenglong City. In fact, it landed at Rilihaikou and cut off the enemy Changyule's retreat, forcing them to retreat in a dilemma." Ruan Youjin said to a confidant and handed him a letter again.

"Yes!" Ruan Youjin's confidant knew that the situation in Changdelei was critical, so he hurriedly threw the city wall after receiving the letter.

"We try our best to win time and wait for reinforcements to come!" Ruan Youjin gritted his teeth.
