Generally, the shelf life of gunpowder is five years. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 If it is in a dry place protected from wind and light, this shelf life can even be extended to more than ten years.

Therefore, the completed rocket launch box was stacked in the third layer of the city wall of Hwaseong.

The four walls of Hwaseong, the entire third layer, and the four kilometers long, are densely packed with rocket launch boxes.

With so many rocket launch boxes, according to calculations, if they are launched, they can shoot every inch of land outside Hwaseong and within the range of rockets.

The fourth-layer city wall of Hwaseong is densely packed with countless rocket launchers, as well as ballistas and eight-bull crossbows.

Calculating the time, it has been more than five years since Wang Hao came to the Great Wilderness.

And the system, there are ten times a day, and in the past five years, even if he only uses the system three thousand times a year, he can still make more than 15,000 kinds of things that the Great Wilderness people can't make.

And most of Wang Hao's production opportunities were placed on the eight-bull crossbow and ballista, as well as the arrow shafts used in the ballista.

It can be said that most of the high-end weapons in Hwaseong were made by Wang Hao using the system.

Of course, the reason why it is said that most of it is because Hwaseong, with the efforts of the past few years, has also produced a unique weapon of high destruction that belongs to the Great Wilderness.

That's the flamethrower.

The flamethrower is a weapon that came into being because of the availability of gasoline.

This weapon, to put it bluntly, is a gasoline canister made of black ironwood, plus the parts of the winch pressurization, and finally a pipe to transport gasoline and a large watering can with ceramic nozzles.

A one-person-tall gasoline tank looks like a round water tower.

The two clansmen had to turn its pressurized winch like a donkey, so that the pressure inside the black ironwood gasoline tank was much higher than the outside.

In this way, once the valve of the pipe is opened, the oil stored in it can be sprayed out.

Pure gasoline is too volatile to be stored in black ironwood gasoline cans.

However, if you add a kind of gum tree resin unique to the Great Wilderness in a certain proportion to the gasoline, it will make the gasoline less volatile like water.

This kind of big killing weapon was an idea from Wang Hao, and then handed over to the carpenter to experiment and complete.

When tested with water, it was able to spray water at a distance of 45 meters.

When tested with fire oil, the actual attack distance reached almost fifty meters, after all, the temperature of the flame was the highest temperature of the outer flame.

This flamethrower has been tested and found to work best against creatures such as dense winged insects.

If the flame burns a little, their wings will be scorched.

The flying insects on the Great Wilderness, which ranged from the size of a fist to the size of a watermelon, would not be able to climb the walls of Huacheng at all once they lost their wings.

In addition, the flamethrower can also be used against dense flocks of birds.

The fire oil spewed out by the flamethrower does not burn out in an instant.

If the oil does not completely burn inside, if it does not come into contact with an object, it will fall from the air to the ground and continue to burn.

However, if it hits something, the unburned oil will stick to the surface of the object like a maggot on the tarsal bone, and then ignite the target along with it.

In other words, if you are swept away by the flamethrower's flames, you will either jump into the river or wait for the fire oil to burn out completely.

In the walls of Hwaseong, in addition to weapons that are not easily exposed to the sun, there are also large quantities of food and various survival materials.

And inside Hwaseong, there are 200 wells.

Although the number of wells is not large, because of the proximity to the big river, the groundwater resources are abundant, and it can be used in the open.

Even if one well only supplies 500 people, 200 wells are enough for 100,000 people to drink.

Three years have passed, and Hwaseong is completely completed.

It took more than four years for the entire Hwaseong Fortress to be completed from the beginning of construction to the completion of the city wall.

There were four gates, each of which had seven gates.

The black ironwood concrete door panel, with a thick layer of molten iron poured on the outside, cooled down, and the giant, the devil ape, and three hundred clansmen worked together to install one side.

The giant tried with his sledgehammer, and if he wanted to make a hole in it, he had to hit more than a hundred hammers with the sledgehammer with all his might.

And the high-level creatures, without the black iron hammer made by the system, want to break through the city gate with flesh and blood, which is basically impossible.

What's more, when defending the city, between the seven city gates, there will definitely be a pile of gravel sandbags, even if the high-level creatures of the Great Wilderness have weapons like a sledgehammer, it is impossible to smash open the city gates.

The craftsmen who had worked hard for four or five years, after the city gate was closed, trembled and deformed hands one by one, and cried with joy.

They looked at the magnificent city wall in front of them and couldn't believe that every brick and tile on it was actually built by themselves.

The Gollum people, after a few years of living in the wilderness, still look funny, but now, looking at the completed Huacheng, they are also shocked.

In the past, I was too busy every day to see the whole picture of Hwaseong.

And now, when you look at it, it feels too unreal.

Hwaseong is taller than a tree.

The walls of Hwaseong are stronger than the mountains.

Relying only on manpower, such an incredible project has been completed, and the gollums, craftsmen, and everyone will leave a name in history in the future.

After the project was over, they all went to the party.

The doors of the cellar were wide open, and the sweet fruit wine was left to their heart's content.

The 80,000 savages in Hwaseong, who have gradually grown over the years, have also been given a three-day vacation and allowed them to rest and rest.

After the craftsmen had enough of revelry, their new task began, that is, to build houses and warehouses in Hwaseong.

Build Hwaseong Fortress into a castle that can be defended for a long time.

It's just that their number is only two hundred.

Because, after Hwaseong was built, every day, every hour, every minute and even every second, there was a team of 700 people training on it.

Whether it's day or night, whether it's lightning and thunder or snowflakes fluttering, there are 700 people on it to defend against monsters and simulate the siege of the city.

In the past three years, Hwaseong has successively absorbed tens of thousands of migrated clansmen.

According to the last census, the population of Hwaseong has reached 300,000.

Among the 300,000 people, even if only 100,000 men have combat power and can be used to defend against monsters attacking the city, the 700 people will be trained in batches, and they will need to be divided into more than 140 teams for training in batches.

In a year's time, if you want all the warriors to go up to the city wall to feel it, then everyone will not spend more than three days on the wall.

Fortunately, among these people, only 20,000 chengguan troops can be regarded as the official army that will defend the city in the future.

The rest of the 80,000 warriors only need to teach them to use bows and arrows, eight-bull crossbows, black crystal bombs and other combat tools in various training bases, and then occasionally let them go up to the city wall to feel the difference in height, and there is no need to let them stay on the city wall for too long time.

After the walls of Hwaseong were built, the savages in Hwaseong went out to help the craftsmen build houses in the city, and the rest went to dig moats outside the city.
