With the order from the commander of the legion, the surrounding Imperial troops immediately blew the trumpet of the charge and bravely rushed towards the fortress, but unfortunately they were all shot and killed by the enemy soldiers inside within a distance of several hundred meters, and several of them were hit by the explosive bags they were carrying, and they also caused a tragic explosion.

"It can't go on like this!" Wang Ping looked at the soldiers who fell on the charging road and said regretfully.

Wang Ping looked around, looking for a good way to attack, and when he looked back, he happened to see a house that had been hit by a cannonball, burning and releasing thick black smoke.

"There it is!" Seeing this scene, Wang Ping had an idea and quickly ordered the soldiers to collect flammable firewood, oil, and green grass and trees.

Both firewood and green trees were easy to find in the city, so soon the soldiers rushed back with a lot of things.

"Tie the dry firewood to the wet green branches, pour oil on the fire, and throw it as far forward as possible."

The soldiers, following Wang Ping's command, threw bundles of burning firewood in the direction of the stone fortress, and these things immediately emitted thick black smoke when they hit the ground.

After seeing these black smokes, the officers and soldiers of the Imperial Army in other directions immediately understood, and hurriedly started to operate in the same way.

Within an hour, the stone bunker was surrounded by smoke, and the Imperial soldiers were throwing firewood forward with their bodies prostrated and wet towels over their mouths and noses.

Under the cover of this primitive smoke bomb, the defenders in the stone bunker saw only smoke in their eyes, and coughed violently under the influence, although they continued to shoot indiscriminately into the smoke, but the lethality had been drastically reduced.

Taking advantage of the smoke and the defenders losing sight, the Imperial Engineer Battalion quickly advanced and placed several huge explosive packets at the base of the stone bunkers......

"Boom, boom, boom ......" was another few earth-shattering explosions.

Gunpowder, a powerful thing, is now used in the Empire in addition to the military, the most common place is mines, it is conceivable that it can even explode mountains, let alone the stone bunker in front of you.

When the fortress collapsed and breached, before the defenders inside could react from the panic, several groups of Imperial assault daredevils threw in a lot of grenades and then rushed in.

Instead of using bulky long-handled muskets, the commandos of the Imperial Army had two of the latest six-round muskets with short handles, and two pistols stuck in their waists, and fired with both hands when they saw the enemy.

This kind of revolver is expensive in terms of extremely fast rate of fire, accompanied by a bang-bang close-range rapid fire, and the Jinglong soldiers in the fortress were shot and killed one after another.

With the commandos attacking, the Imperial army that then rushed in ascended to the second floor and wiped out the remnants of the enemy, while more people searched for secret passages to the underground.

The Duan brothers were also deliberate, and after some searching, the soldiers finally found the entrance, but they couldn't attack it for a while.

In this era, when building city walls or high-rise buildings in various countries in the past, stone was used as the main material, and glutinous rice soup mixed with lime mortar was used as the binder.

Since Li Nan and others brought back the manufacturing method of cement from the world of ice and fire, this stronger cementitious material quickly replaced the previous adhesive as soon as it appeared.

Nowadays, the empire's roads, houses, dams, and other buildings are made of cement, and because this commodity used among the common people is not considered a military material, and it is difficult to control, it is also exported to neighboring countries.

The stone fortress of Jinglong Jindian Kingdom, as well as this underground passage, are all made of stone and cement, and the dead soldiers of the Duan family who are guarding the entrance of the secret passage at this moment rely on the entrance of the passage that is easy to defend and difficult to attack, resisting the incoming imperial army.

In this kind of underground building, it is easy not to use grenades and explosives bags, otherwise once the passage is blown up and collapsed, it will be difficult to continue to pursue the fleeing Duan family brothers.

Seeing that the enemy's dead soldiers blocked the door and could not use explosives, Wang Ping was immediately angry, and took a spear from the hands of the soldiers beside him: "The person His Majesty the Emperor wants to arrest will definitely flee in front of us, and he who is not afraid of death will follow me!" ”

Just when these dead soldiers of the Duan family were strictly guarding to the death, Wang Ping led the elite of the reconnaissance battalion to rush into the underground secret passage with cold weapons.

Wang Ping's father is Wang Yin, a general under the command of Fang La, a man of both humanities and martial arts, an official who worships the Shangshu of the Southern Kingdom, is accustomed to using a steel spear, and is known as the head of the Eight Heavenly Kings.

Wang Yin is good at using marksmanship, even if he competes with Lin Chong and others, it is not much worse, and Wang Ping, as his son, has the essence of family marksmanship.

At this time, Wang Ping rushed into the underground secret passage with a silver spear, and with one move, he fired a hundred blows, and conjured up a gun shadow to cover several dead soldiers in front of him.

As the saying goes, a soldier is the power of a general, and it will be the courage of a soldier, with Wang Ping's fierce attack, and then the imperial warriors quickly followed up and fought hard.

Seeing that the imperial army actually rushed up, several dead soldiers of the Duan family immediately put the torches in their hands towards the lead of the explosives, seemingly wanting to die with the enemy, and by the way, also blow up this secret passage.

"Don't think!" Wang Ping saw the actions of these dead soldiers, and immediately threw the spear in his hand, nailing one enemy to the wall, and then touched the boot with his right hand, pulled out the dagger and engaged in hand-to-hand combat with several other enemies.

Because there are a lot of explosives in this underground tunnel, the imperial army is bound and cannot use the firearms they are accustomed to, but fortunately, there are many people with superb martial arts like Wang Pingren, which stopped these dead soldiers who were not afraid of casualties.

As Wang Ping and others fought, more and more imperial troops poured in, and it soon became clear that the remaining enemies were left.

As Wang Ping, who was at the forefront of the battle, saw that his side was in control of the situation, and hurriedly led a team of men and horses to chase after him to the depths of the dark tunnel......

Since Jinghongcheng has been captured, even if the Jinglong Jindian Kingdom has been completely destroyed, it is still resisting the enemy of Zhang Shuye's Eighth Army in the Mekong River Valley, and soon chose to surrender after Paya Zhen came forward.

The imperial army's attack on Jinglong Jindian Kingdom was indeed a bad thing for the Duan brothers, but it was undoubtedly a good thing for many Dai and Bai people.

Although Duan Zhengchun and others are also considered Ming monarchs, and they govern the Jinglong Golden Palace Kingdom in an orderly manner, they are definitely not comparable to the powerful empire.

Because no matter in terms of infrastructure, living conditions, and the area of arable land owned by individuals, the empire treats the people to the extreme, especially the extremely low taxes, which are the envy of the people of other countries.

In fact, for many people in the Jinglong Golden Palace, they didn't want to go to war with the empire.

Because the people here are mostly Dai and Bai, many of them are related to the people of the neighboring imperial provinces of Dali, Zhenla and Bagan, and they are all people of the same race.
