Even if the enemy rushed to the front, the flintlocked spearman was not a lamb to be slaughtered. The musketeers in the front row holstered the musket, and the musket turned into a short spear. With the cooperation of the iron armored soldiers, they kept stabbing the triangular bayonet into the enemy's body.

The attack on the Dagukou Fortress by Goryeo Bangzi was like filling a well with snow. Many people came up for free. After more than an hour of fierce fighting, more than half of the 20,000 Korean sailors lost more than half of them, and more than 10,000 corpses were left halfway and on the platform of the castle. The remaining less than 10,000 Korean sailors ignored the supervision team and finally retreated.

However, there were also casualties in the Ming army. An iron-armored soldier was split with an axe by a North Korean sailor, resulting in serious injuries. Six musketeers were killed by the North Korean sailors who rushed in front of him. Five other iron-armored soldiers and nineteen musketeers were injured in the battle. In addition, more than 20 non-combat casualties also occurred among the auxiliary soldiers.

Non-combat casualties, some were because the gun barrel was too hot, and the auxiliary soldier accidentally touched the bird gun barrel and was burned; some twisted his feet when entering and leaving the bunker; some were accidentally burned by a fuse on his face; the most serious thing was that the fuse hanging on his neck accidentally ignited the gunpowder on his comrades around him, causing the ammunition on the soldier's body to explode, causing the auxiliary soldier to die.

However, among all the non-combat casualties, there were no casualties caused by the explosion of the bird gun barrel, which shows that these firearms supervised by the Jinyiwei are of great reliability. Compared with the firearms supervised by the Ming Dynasty's Ministry of Works, the quality is many times more reliable.

The bird guns in the auxiliary soldiers can ensure that each gun barrel is fired three hundred times without blowing up. These bird guns are new bird guns made by the Jinyiwei after Zhao Peng arrived in Nanjing. The straight barrels are much more beautiful than the stupid, stupid and thick old bird guns. There are no burrs or potholes on the inner wall of the gun barrel, which greatly improves the accuracy and increases the effective range from fifty steps to seventy steps.

The stock that was originally bent downward has also become a straight stock. The tail of the stock of the old bird gun was originally bent downward, forming a grip, and the trigger is on the grip of the tail of the stock. The new bird gun uses a straight stock, and the trigger position moves forward. Under the guardrail in front of the stock, a guard ring is added outside the trigger to prevent other parts of the body from touching the trigger.

Moreover, the straight stock allows this bird gun to use the stock to press the shoulder to shoot when shooting, increasing the stability of the shooting. Because it is not easy to cause a blast accident, when using the bird gun to shoot, you can put your face close to the bird gun and conduct precise aiming and shooting.

Similarly, the turtle dove gun in the hands of the auxiliary soldiers equipped with the turtle dove gun is also a newly built turtle dove gun. The quality is much higher than before. The barrel can be fired three hundred times without blowing the barrel. There are no burrs or potholes on the inner wall of the barrel, which improves the accuracy. Moreover, the reliable quality of the barrel also increases the charge volume and increases the power.

The new turtle dove gun can be filled with four liang of gunpowder and fired 4 liang of projectiles, which have extremely strong penetration power. The turtle dove gun weighing 20 jin has the same power as the same light Franchise machine weighing 100 jin.

Zhao Peng had a total of 50,000 new troops, and only the 10,000 new troops who came to Dagukou this time were replaced. The remaining 40,000 new troops who had not been replaced used were the same weapons as the auxiliary soldiers here, both were new bird guns and new turtledove guns.

As for the flintlock rifle in the hands of the new army, it is the most exquisite weapon, with a barrel life longer than the new bird gun, reaching 500 rounds. Although each of the new army soldiers who came to Dagukou this time carried two spare gun barrels, they repelled the Qing army's three attacks in a row, and were far from being able to replace the gun barrels.

However, the fifty bullets carried by each soldier have been fired, and most of the fifty bullets just received from the ammunition box have been consumed; all the wooden handles of the iron armored soldiers have been used up, and the shells in the artillery are about to be consumed. What is needed most now is to replenish ammunition.

Taking advantage of the time when the Qing army retreated, the 50,000 auxiliary soldiers who stayed behind were nervously transporting the ammunition that had just been unloaded from the beach to the castle.

The small sampans of the Ming army's naval division leaned on the shore one by one. The auxiliary soldiers immediately stepped forward, brought boxes of ammunition and food from the boat, carried buckets of fresh water, and brought these supplies into the cart, and then along the simple stone road in Pucheng on the beach, they sent the goods that had just been unloaded from the boat into the castle.

Zhao Peng stood at the highest point of the castle and used a monolithic mirror to observe every move of the Qing army's positions in the distance. At this moment, he vaguely discovered movements on the rivers and seas in the distance.

"Release the hot air balloon!" Zhao Peng shouted.

On the high platform, several Jinyiwei opened a large box, dragged out a folded hot air balloon from the box, unfolded it on the ground, and then moved the oil stove, oil tank and pressure booster from another box, and assembled it on the ground.

The oil stove, oil tank and pressure regulator were placed in the hanging basket of the hot air balloon. Then a Jinyiwei shook the hand-crank blower and poured the air into the hot air balloon, causing the hot air balloon to expand.

After the hot air balloon expanded, a Jinyiwei lit the oil stove, and the flames on the stove began to heat the air in the hot air balloon airbag. After a while, the hot air balloon airbag did not need Jinyiwei to hold it with her hands, and she could stay in mid-air by herself. She also pulled the hanging basket slightly, but the buoyancy was not strong enough now to drive the hanging basket to air.

Chen Xinyuan jumped into the hot air balloon's hanging basket with the latest pair of binocular mirrors.

The binocular trimicular mirror is the latest style of trimicular mirror made by Zhao Peng not long ago. Since it does not require one eye to close like a monocular trimicular mirror, it has a wider field of vision and larger multiples, and looks clearer.

After Chen Xinyuan jumped into the hot air balloon hanging basket, he pressed the pressurization handle several times with his hand to compress the air in the pressurizer, and poured the air into the oil tank through a tube made of Eucommia glue.

The oil tank was under pressure, and the tinder oil contained in it was sprayed, spraying out from the stove nozzle. The originally swaying flame suddenly became larger and burned more violently. The flame heated the air in the airbag, and the hot air balloon began to slowly take the basket, slowly lifted off the ground, gradually leaving the ground.

The hot air balloon slowly rose and rose into an air about a hundred feet high. The hanging basket that continued to rise made the cable tightly tight, and the cable had been straightened. So Chen Xinyuan reached out and pulled the switch. The flame on the stove became smaller, which made the cable relax a little.

If the cable is broken, it will be difficult for the hot air balloon to come back. Once the cable is broken, even if the flame is closed, the hot air balloon will be blown away by the wind. I don’t know where to blow it to the ground. It would be fine if it falls into the sea. There are so many ships on the sea that can save the people on the hot air balloon. But if it falls into the Qing army's position, it will be miserable and the people will be captured by the Qing army.

Chen Xinyuan shut down the flames in time and let the hot air balloon float in the air. He picked up the telescope and observed the Qing army's position. He saw that the Qing army was killing people again. Many Koreans were kneeling on the ground, and there was an Eight Banners soldier standing behind them. Then the Eight Banners soldiers raised their swords and fell on the ground. The Koreans kneeling on the ground all fell to the ground.

Turning the telescope to look at the Haihe River, I saw a huge fleet of ships appearing in the upper reaches of the Haihe River to the west, heading towards the Qing army's positions.

Not long after, the Qing army fleet docked on the dock beside the position of the Qunta, and groups of Eight Banners soldiers came down from the ship. Finally, the Green Camp soldiers carried various items and pushed red barbarian cannons down from the ship.
