Many generals of the New Army also believed that this type of musket, which could shoot far and hit hard, could be used as a means of attacking important enemy leaders.

Zhang Pan did the same thing, selecting thirty strong and muscular soldiers to train them specifically in shooting with eagle guns.

The effective range of the Rumi gun is about 50 meters, and the maximum range is 150 meters; the Eagle gun has a range of 100 meters and 250 meters respectively.

Of course, accurate shooting with muskets at that time was difficult, but the tactic of concentrated fire could still make up for the shortcomings.

At this moment, the ten Eagle Gunners behind the breastwork finally had their chance to show their prowess. Following the officer's orders, they loaded their ammunition with the maximum charge and aimed at Zaisanggu, who was 150 to 160 meters away.

Such a long distance was something the Eagle Gunners had never attempted before. Based on their respective shooting experiences, they adjusted their angles differently.

Strictly speaking, this was rough shooting, almost entirely based on guesswork. Whether or not you could hit the target depended more on luck.

"Boom!" Almost at the same time as the officer gave the order, ten eagle guns fired 40-gram lead bullets from different angles and flew towards the target.

Zaisanggu was completely unprepared. He looked at the miserable battlefield with gritted teeth and forced himself to suppress the urge to mobilize troops to continue the attack.

The sudden roar and white smoke from the Ming army's position did not attract Zaisanggu's attention. But in an instant, lead bullets were already fired at him.

Right next to Zaisanggu, a personal soldier suddenly fell off his horse, spitting blood.

The lead bullet hit his chest. Although it did not penetrate, it was like a hammer hitting him, and blunt trauma was inevitable.

Before Zaisangu could react, a lead bullet hit his left cheek at an angle by sheer coincidence.

Then, it was no longer a bloody mess, it was almost like a rotten watermelon being smashed to pieces.

With a mournful cry, Zaisanggu's horse was shot and fell to the ground with a thud.

Under the stunned gaze of several bodyguards, Zaisanggu, with most of his head smashed, fell straight down like a brilliant firework.

This, is this the brave and fierce Zaisangu Beile who is good at fighting?

The guards slowly regained consciousness, leaping from their horses with cries of shock and tears, and helping the now unrecognizable Zaisanggu to his feet, their hearts aching as if they had lost their parents. Why? Their commander had been killed in battle, and they were responsible.

Through the telescope, Zhang Pan smiled with satisfaction as he watched the Jiannu soldiers crying and carrying corpses away.

He Kegang put down the telescope, very excited and happy, and said: "If the Jiannu get angry and attack desperately, that would be great."

Zhang Pan twirled the telescope in his hands and said with a smile, "I thought so too, but I'm afraid the Jiannu won't fall for it so easily."

He Kegang chuckled and said, "He looks like a big boss. Maybe he's here to seek revenge!"

"I hope so." Zhang Pan nodded slightly and issued orders to the generals to treat the wounded, prepare enough ammunition, and prepare for battle.

After this defensive operation, Zhang Pan and He Kegang became more confident and more certain of defeating the enemy.

According to the observation of the two generals, the Jiannu army had less than 10,000 people, and the 3,000 musketeers and 2,000 spear, sword and shield soldiers in Lushun Fort were enough to resist.

If the Jiannu dared to divide their forces and surround the enemy on all sides, Zhang Pan would be prepared to concentrate his forces to turn defense into offense and attack one side.

What's more, there is a signal ship in the harbor that can send messages through fireworks to contact Zhang Bang and He Zan to come. With the attack from both inside and outside, the Jiannu will undoubtedly be defeated.

Of course, Zhang Pan also felt a little regretful. If the Dongjiang Army had received reinforcements, such as Kong Youde's Right Brigade, it would have been very likely that they would have completely wiped out the attacking Jiannu.

Not to mention that the defenders of Lushun Fort adjusted their deployment and prepared to meet the attack of the Jiannu. At this time, Amin and Jirgalang were holding the bodies of their brothers and crying loudly.

It was just a tentative attack, and any further attack by General Zaisanggu would not be considered a serious attack. Amin and Jirgalang watched from a distance and were not too worried about Zaisanggu.

But in the blink of an eye, the situation suddenly changed. The Ming army launched crazy bombing and intensive musket fire. The fierce firepower quickly defeated the attacking troops.

Amin and Jirgalang were also surprised and shocked. They understood some of the secrets of the Ming army's formation and knew that they had been tricked.

But it didn't take long before the body of Zaisang Gu, who was dead and in a mess, was carried back by his personal guards. This made the two of them unable to believe their eyes and even more unbelievable.
