Dou Mingwang's work was effective. He continued to send a large number of white skins to the front line of Bratislava Castle. Ma Bao then drove the white skins forward without mercy to fill the ravines!

Crying sounds shook the sky, screaming endlessly!

Those white-skinned chicken buses loaded with mud, sand and gravel, or carrying sand and gravel bags, rushed to fill the wide and deep trenches in front of the castle under the bayonets of the South China Army.

The gun holes on the city walls and the battlements were sprayed out, and the defenders' guns and cannons fired volleys.

They also raised their big bows and shot arrows. The arrows were like rain.

There were also stone bombs, bombs and sulphur bombs fired by the trencher, crossing the sky and landing in the white pile of white skins under the city and exploded.

War is the best technical catalyst. The "firepower attack" mode of the South China Army was learned unstoppable by the defenders, maximizing the firepower to increase its lethality to the enemy.

Now white skin is made of white skin, and the white skin on the city is not ruthless. The white skin under the city falls down like harvested wheat, and blood flows into the ditch, and soon a blood groove forms.

The stormy firepower could not stop the white skin from working under the city. It threw sand and gravel and pushed the body into the ditch, which was slowly filled.

In the past, the South China Army sympathized with the misfortune of the people who filled the gully and distributed some protective gear to them to increase their survival rate. However, afterwards, some of those people resisted, and the protective gear became their accomplices. After that, there were no protective gears for them and they were allowed to run away.

As for why most people would rather fill the gap than resist, it is because there is something more terrifying in the world than death, "I can't survive, but I can't die." The South China Army is a pirate in its bones, and pirates are not good at plagues!

The South China Army was still kind. They provided fire cover for the work of the white-skin under the city, suppressed the firepower on the city, and sniped the defenders.

Musket fire, artillery bombardment, bomb throwing and bows fire.

Both sides fought back and forth, and they were all given up.

The defenders on the city were calm and the casualties were very small.

In order to deal with the attacks of the South China Army, they were equipped with protective gear, helmets and armor, and the terrain was high and the fortifications were complete, which played a good protective role.

Ma Bao saw from the telescope that the defenders had good firepower. He never believed in evil and immediately instructed the army to concentrate their firepower to bombard the eastern section of the castle.

Heavy weapons, including counterweight trenchers and Thor Hammers, have not yet come up, and using a 12-pound marching cannon to fire a few shells on the city wall, it is just a few white ideas!

The armored grenades of the South China Army rushed up and threw a large number of bombs, sulphurs and poisonous gas bombs.

The bombs bloomed on the city wall, and small mushrooms rose.

The explosion was very powerful, and even the city was shaken.

Unfortunately, there is no real posture. Most of the city walls have ceilings, spaces, and are very strong. Some are just bunkers. In this way, the lethality of the bomb will be severely weakened.

After all, the black gunpowder bomb is not yellow explosives and cannot destroy the fortifications on the walls.

Due to the existence of fortifications, the power of the sulphur bomb was also weakened. For example, for the bunker, even if the sulphur is lit on the fort, the people inside will not be affected, and the back of their bunker is open to ventilation and cooling.

The white skin was obviously prepared, and when the sulphur bombs were lit in some open places, they covered the fire with mud!

Can poisonous gas bombs work?

Ma Bao used a cannon-type telescope, which clearly saw the white skin on the city wall. What shocked him was that the white skin also wore a gas mask similar to the pig mouth-shaped one of the South China Army on his face, and he moved freely in the poisonous gas, which shocked Ma Bao and the officers. Could it be that the secret of activated carbon was lost?

The Nanhua Army gas mask contains activated carbon, which puts organic materials rich in carbon, such as coal, wood, fruit shells, coconut shells, walnut shells, etc. into the activation furnace, and is converted into activated carbon by pyrolysis under high temperature and certain pressure.

Activated carbon has a wide range of uses, especially for military purposes. It is impossible for the South China Army to encounter clean water sources during its expedition. It is one aspect to use activated carbon to filter sewage for drinking, and it is also good to use it as adsorbents in gas masks.

Its technical content is not high, but white skin cannot be made.

Inspired by Yan Changwu, experts and technicians of the South China Empire invented activated carbon with coconut shells that are widely present in Nanyang, which was listed as the "high technology" of the empire. They are listed as the country's high secrets with porcelain production, silk production, tea seeds, etc., and who dares to leak out and kill whoever is the head of the family, so the secret of activated carbon has been preserved.

Now it seems that white skin also uses gas masks. Did they also use activated charcoal?

Later I learned that China has activated carbon and white skin has peat!

Peat, also known as peat, peat soil, black soil, peat coal, is the coal with the lowest degree of coalification and the most primitive state of the breeding coal series. It is often accumulated in peat bogs. Later, under the pressure of overlying sediments and further bacterial conditions, it becomes stronger after compression and dehydration, and becomes lignite. When it continues to be affected by underground temperature and pressure, bituminous coal or anthracite is formed through coalification.

Peat organic matter is fine fiber or sponge, with high porosity and large specific surface, strong adsorption effect, and can absorb water and gas.

The South China Empire used poison gas bombs to attack the Ottoman Empire, and then the South China Army equipped with gas masks attacked. The Ottomans coughed heavily in the poison gas, but the South China Army was not affected.

At that time, the Ottoman Empire hired some white-skinned guns to assist in the war, mainly using artillery artillery, and came to the country to help fight foreigners, mostly Italians, and used Italian guns to attack the South China Army.

The Italians collected some gas masks abandoned on the battlefield and brought them back to China.

Once they analyzed that activated carbon was not white, they tried to produce it but failed, so they looked for alternatives, but they found it.

It's peat!

Not all peat is useful. After all, peat in some places can absorb poison gas. They put peat into pig's mouth. Without sealed rubber, they use soft skin instead. As for lenses, Yidian has high glass manufacturing technology, which is not as efficient as the Chinese, but can also make glass lenses.

So as soon as I made up my mind, Baipai also created an emergency version of the gas mask!

To be honest, the gas mask of the white-skinned pig is not very good. Compared with activated charcoal, peat has a strong earthy smell and the smell it smells very bad. Unlike Nanhua's coconut shell activated charcoal, it has a refreshing fragrance.

The sealed edge made of leather is not as good as the rubber edge, and you can still absorb some poisonous gas.

But it’s better than nothing. You can gain a foothold on the wall by using a gas mask.

If the poison gas is richer, such a gas mask will be harsh. At this time, the benefits of the big castle will be revealed. The place is large and the poison gas is diluted. The terrain is high. When the wind blows, the poison gas will not be poisoned.

Even though the South China Army gritted its teeth and threw a bunch of bombs, ignite oil bombs and poisonous gas bombs to the city, it failed to achieve good combat results. In addition, the city was high, so we could only wait for the arrival of heavy weapons.
