Struggle in the Steam Age

The human counterattack went very smoothly, and soon they cleared the group of goblins gathered in front of the barbed wire. The goblins who were cut off by the shells in the rear could only watch as their front companions were completely wiped out.

But mortars can’t keep firing, even if the dwarves added a lot of magic metal when the mortar barrels were made, but the level of steel in this era still makes Lawrence’s strict requirements for the weight of the artillery. Mortars cannot be fired continuously in a short period of time.

Therefore, after each cannon hurriedly fired 20 rounds, it had to temporarily stop firing to let the barrel cool down. While waiting for the cannon to cool down, a visible light from the back of the goblin swept the battlefield. All the goblins on the road, and then the goblins who began to flee, mustered up the courage and rushed up again.

"Large-scale magic." Lawrence recognized what the goblins were doing at the moment those lights appeared, and Nora, who was scouting in the air, also saw what was hidden before the goblins.

"Brother, the other party has hidden an altar, and it is of a high level." Although relying on the cover of divine power, the goblins succeeded in successfully moving an altar to a distance under the condition of Lawrence and their repeated investigations before the battle. The raid mission was perfectly achieved close to the battlefield. But after casting the magic, the altar that was the source of the magic could not be hidden, and it was quickly discovered by Nora who was watching from the sky.

"Should I destroy that altar now? The other side's altar is hidden among several hills and only a few people guard it. If there is a sneak attack, I personally think it is not difficult to take down the altar." The first time I found the altar, Nora Just contact Lawrence and ask for instructions.

"There is no need to take risks." Lawrence said, stopping the eagerness of Nora. "My secret weapon is also ready. Now it is a good thing to let those goblin pigs charge forward, so that I can kill them all at once. Catch all the goblins who are escaping in the forest."

As Lawrence was talking, a large number of yellow-green bottles with white paint on them with tap water disinfectant were taken from the underground warehouse temporarily dug out of the settlement and sent to the trenches on the front line. At the same time, another batch of mortar shells dyed a pair of yellow-green warheads were sent to the artillery positions.

"Let's implement the final plan." Watching the second-line trench and the mortar position raise a red flag at the same time, Knight Lawrence Joseph said. "I think it's time now, and the wind direction and wind speed are also very suitable."

"You're right." Take a closer look at your own flag on the battlefield, and then at the passages that protruded from the fallen goblin corpses all the way forward, the first trench from the main attack direction of the front battlefield. Goblin community coming closer. The Joseph Knight immediately issued an order to the messenger behind him. "Send a signal to raise the red flag that represents the front battlefield."

Soon, a red flag rose behind the command post. The frontline commanders who had been staring at the command post before saw the signal and immediately blew the copper whistle hanging on their necks.

In the rapid sound of the copper whistle, the batch of flat wooden boxes that had been placed in front of the trenches with this face-facing enemy exploded one after another. After that, the lid of the wooden box was broken and the steel **** flew out in a fan shape. The goblins not far from the position were swept away. Taking advantage of this gap, the soldiers in the trenches retreated to the rear following the traffic.

When everyone retreated, the goblins whose offensive momentum was knocked down by the directional thunders placed in front of the position just now came up like a tide again. This time, because of the retreat of the guards in the trench, they easily rushed to a place only ten or even a few meters away from the trench. In some places, some goblins even enthusiastically squatted on the wire fence, and then let their companions step on their bodies and rushed into the trenches over the last section of the wire fence.

"Beep—" There was another fierce whistle. More than 100 people wearing rubber raincoats and wearing rubber gas masks that looked a bit like pig noses quickly opened those placed ten meters behind the first trench. A green steel cylinder placed on the edge of the second trench.

In a moment, thousands of steel cylinders released a large amount of yellow-green gas at the same time. Then, under the breeze blowing from the sea to the land, it spread to the front of the position. At the same time, the mortars shot the prepared special shells at the back of the goblin army, creating patches of yellow. Green gas barrier.

After being exposed to the green gas, the goblins fell in pieces like wheat cut by a sickle. This made Fatina, who was standing next to him, a look of doubt on her face.

"Smelly Cloud Technique? Lock Throat Poison Gas?" Fatina whispered while watching the fallen goblins, "How many scrolls are needed to cover the entire battlefield."

Unlike Lawrence's previous life, people in this world have no moral problems with the use of poison gas. It's just that because the previous poison gas is all related to magic, it can't be popularized in application.

"This is the power of science and knowledge." Seeing that the overall situation on the battlefield can be considered settled, Lawrence turned his head easily and said to Fatina, "I didn't use any magic scroll, just bought it from the Federation. It’s only 30 tons of chlorine."

After the last outbreak of typhoid in Eagle Fort, the Federation began to seek solutions to urban water pollution. After all, the attack made the Federation realize that although the water supply system in densely populated areas like cities is much safer than those shallow wells dug privately in the past, it is really prone to the spread of such large-scale diseases.

Lawrence, as a member of the Federal Science Association, naturally received a letter of inquiry. After receiving this letter, Lawrence only thought about it briefly and came up with a response plan. This scheme is actually very simple, and that is to use chlorine to disinfect tap water.

After all, this scheme has been used for more than 100 years since it was invented in the world of his last life, and it has been used by various water plants until Lawrence accidentally came into this world, so there must be an excellent aspect.

Finally, when Lawrence returned from the Republic of New Africa, he received a letter from the Federation, which indicated that his plan was adopted by the federal government because of its low cost and simple operability.

Although at the beginning he was a little worried about how they could get cheap chlorine without electrolysis~www.ltnovel.com~, but then he learned that electrolysis can be replaced by a simple magic. In our opinion, the chlorine decomposed from the salt water can be used for three days in a big city like Eagle Fort as long as an hour or so is busy.

In addition, the developed steam engine industry can also provide sufficient pressure vessels for the transportation of chlorine. Therefore, as long as a few wizards are hired to build a chlorine production plant by the sea, the chlorine can be easily transported to major cities by rail. It is also much more versatile than other methods.

Therefore, when Lawrence obtained the title of earl, chlorine disinfection had begun to become popular in the major cities along the coast of the White Eagle Federation, and it was rapidly spreading to the inland cities.

It was in this case that Lawrence successfully obtained 30 tons of chlorine gas to create a batch of steel cylinders and special ammunition for casting. They were transported by Safir’s ships before, and they are all used on the battlefield today. on.

Now it seems that the first use of this poisonous gas is very effective, as the gas continues to spread to the group of goblins, most of the physical fitness is not as fast as the human goblins die. Although the few bear goblins, hobgoblins, and after all, those who are mixed with ordinary goblins, can resist the attack of poison gas on them, their scattered rush to the second trenches are only for the guards who are waiting for them. We give away the heads.
