Amin nodded in agreement and issued an order, ordering the Han army to form a battle array and launch an attack in the north of the city.

The Han army that came with them was not large, less than 2,000 men. Amin did not expect them to break through the enemy's defenses in one fell swoop, but just wanted to see if there was anything tricky about the enemy's arrangements.

To put it bluntly, it was a test. They used the Han army's worthless lives to launch a test attack and consume the Ming army's ammunition.

When the Jiannu army was mobilizing its troops and deploying their battle formations, Zhang Pan had a brief discussion with He Kegang and made corresponding adjustments.

Spearmen, sword and shield soldiers, and archers moved forward through the trenches, assisted by a small number of musketeers, to engage the surrendered Han army head-on.

More musketeers quietly gathered on both wings of the enemy's attack surface, forming cross fire and launching fierce and fierce attacks on the enemy.

He Kegang also transferred his own 1,000 musketeers from the fort, originally intended to be used as a reserve force. However, this aid to Dongjiang was to train the troops in actual combat, so why not take advantage of the opportunity?

Zhang Pan believed that the main focus of fully utilizing firepower should be on attacking the Jiannu. If the Jiannu were exposed in advance, they would probably be frightened and dare not attack.

As for the Han army, their equipment is poor and their combat effectiveness is not high, so it is not worth wasting too much ammunition.

The shields provided protection in front, the archers were responsible for suppression and cover, and the Han army, armed with swords and spears, slowly approached the trench.

This is a shelter trench that is more than two meters wide and three feet deep, with many half-foot-high pointed wooden stakes buried in the trench.

It's a bit strange, isn't it? It's three feet deep, but waist-high. You don't even need to fill the trench, you can just rush over and kill them by avoiding the sharp wooden stakes.

But this is a new tactic developed in martial arts, designed to draw the enemy into a direct attack. The trench is not meant to block the enemy, but to delay them, giving the musketeers more opportunities to fire.

The reason is simple. If you think you can wade across a small river, would you bother to build a bridge?

Moreover, this will not only delay the enemy's advance, but will also become an obstacle when the enemy retreats.

Of course, any new tactic had to be tested in actual combat before it was introduced, but Zhang Pan and He Kegang's boldness in using it at Fort Lushun showed their full confidence.

Sure enough, this formation allowed the Jiannu to launch a tentative attack without much preparation.

Whoosh, whoosh, whoosh... Clusters of arrows rained down across the trenches and landed on the Ming army positions. Protected by the breastwork trenches, the Ming army soldiers could not be harmed at all, except for the unlucky ones.

Holding shields and following the officers' howling commands, the Han army jumped off the trench, paying attention to their steps, and slowly advanced forward.

There was no movement from the Ming army's position. They watched as the enemy crossed the trench and climbed the three-foot-high rim. Twenty meters away was a row of deer spurs and wooden stakes nailed to the ground.

The arrows shot forward, neither densely nor fiercely, which seemed to add courage and boldness to the Han army's attack.

"Go, go!" the officer urged, "Charge!"

The Han army continued to advance, fifteen meters, ten meters...

Boom, boom, boom...

More than a dozen cannons roared from behind the wooden stakes. There were Portuguese cannons and tiger squat cannons. They spewed out fireworks and fired countless pieces of stone and iron at the Han army head-on.

This was a fierce blow, and also the beginning of a defensive battle. The arrows became denser, and the Portuguese quickly replaced their cannons and continued firing.

About a hundred muskets also began firing, using a burst of five rounds. Amidst the rising white smoke, the sound of gunfire was so frequent and short that it gave the illusion of continuity.

Amidst the flash and white smoke, the lead bullets instantly flew over a distance of fifty or sixty meters, easily piercing through the enemy's armor. Dirty blood spurted out from the holes, turning into streams of blood arrows.

The officer howled loudly, ordering the archers to cover and suppress the enemy with all their might, and urged his men to continue moving forward.

But his voice suddenly stopped as a lead bullet hit his abdomen, and the armor could not block the roar of death.

The officer fell to the ground, covering his wound, struggling in pain and letting out a heart-wrenching scream. Blood instantly dyed his robe red.

The cannon fire had subsided, but the muskets continued firing, and more and more enemies fell before the wooden stakes in the Deer Fort. The archers who were responsible for covering the enemy were already weak and exhausted, and their arrows were shot weakly.

But the enemy still approached, holding up their shields, and began to use swords, axes and guns to destroy the obstacles in front of them.

The sound of war drums rang out, and the Ming army spearmen, wearing helmets and armor, jumped out of the trenches, rushed forward shouting, and shot their spears across the wooden stakes of Luzhai.

Puff, puff, puff... accompanied by the horrifying sound of sharp weapons piercing flesh, the enemies who rushed to the first row let out screams and wails. The sharp spear tips tore through their armor and stabbed into their bodies, carrying broken bones and rotten flesh with them.

The Han troops behind surged forward, their spears raised, stabbing forward. Across the barrier, both sides glared in anger, the shining, blood-stained spear tips retreating and retreating, and men continued to scream and fall in pools of blood.

Looking at the close combat ahead, where the Han army was already showing signs of exhaustion, Zaisanggu smiled grimly and glanced at Amin.

Amin nodded vigorously, feeling that the time had come. If the five powerful Niulu rushed forward, they would surely defeat the enemy and destroy their defenses.

The horns wailed, the drums roared, and the more than a thousand Jiannu who had been waiting in formation let out wild animal-like howls and charged forward.

The sound of flags and drums also changed here. The spearmen quickly retreated and entered the trench breastwork. A hundred musketeers then fired a fierce volley, nearly bringing the Han army, which had already suffered heavy casualties, to its knees.

At this moment, the order to retreat finally came. Seeing the incoming elite troops, the Han army felt as if they had been pardoned and wisely moved aside.
