The city was filled with water for five days, and everything that could be stored was filled with water.

Xia Hongsheng had the corpses of people and livestock caught in ropes and sunk into the water.

There were no corpses floating down from the upstream, and the downstream could not tell that the water source had been polluted just by looking at the water.

Xia Hongsheng climbed the city tower and watched the big cannibal draw water from the river from afar with a telescope. The weather is hot, and the big cannibals are not in the habit of boiling water before drinking.

In the city, Xia Hongsheng had already ordered his soldiers to dig out the sand kiln, and then dug up fine sand and burned it with coal.

In medieval Europe, alchemy was once prevalent. Alchemists are obsessed with finding the legendary Philosopher's Stone, so that they can turn stones into gold, and ordinary lead and iron into precious gold. The alchemist, like a madman, uses strange vessels and substances, reciting incantations in his mouth, refining in the fire, stirring in the vat, and searching for the stone of the sage that can turn stones into gold. In the seventeenth century, a German merchant who was keen on alchemy, in the process of calcining sand and evaporating human urine with strong heat, did not make gold, but unexpectedly obtained a substance like white wax, which glittered in a dark hut. This is phosphorus. By distilling this phosphorus, you can get an extremely dangerous, unstable, and highly toxic substance - white phosphorus!

White phosphorus is extremely unstable, with a very low ignition point, and can burn violently at about 40 degrees. And its combustion can release highly toxic, after inhalation, it can make the human body have a strong toxic reaction, so that systemic bleeding, hematemesis, blood in the stool and circulatory system failure and death. Even if you don't die for a while, you will die of disease due to liver, kidney, and cardiovascular insufficiency.

The incendiary bomb made of white phosphorus as a filler is a white phosphorus bomb. The white phosphorus bomb is very harmful, it burns continuously after touching an object, and it will not be extinguished until the white phosphorus is consumed. Therefore, when it comes into contact with the human body, the flesh skin is penetrated and then all the way down to the bone marrow. White phosphorus is difficult to remove in time when it gets on the skin, and the burning temperature is high, which can burn all the way to the bones, and the smoke produced at the same time is extremely irritating to the eyes and nose, and it is highly toxic, which is a very dangerous and cruel weapon.

At the temperature of the big food, if the white phosphorus sticks to it, it does not even need to ignite, just a little patting, the white phosphorus can immediately reach the ignition point due to friction, burn violently, and release a large amount of toxic smoke.

Naturally, you have to be very careful when manufacturing, and if you are not careful, you will go first.

"Brother Sheng, what are you doing? What is this big fire to cook urine, before the big cannibal attacked, he smoked himself to death first! Su Dingfang pinched his nose and complained to Xia Hongsheng: "Just cook urine on your fire, and the rations of the soldiers in the city can last a few more days!" ”

"What is it called boiling urine on high fire, it is obviously soaking sand with urine and then burning sand!" Xia Hongsheng said to Su Dingfang angrily: "You don't have to get close if you have nothing to do, what you make there is very dangerous." ”

"Lao Su will not come near there if he dies!" Su Dingfang looked resentful, let go of his pinched nose and sniffed it on his body, and said, "If you rush out at this time, you will definitely be able to smoke the big cannibal to death!" ”

Xia Hongsheng shook his head and passed by himself.

When the mixture of sand and urine is calcined over a large fire, it burns out something like white wax, which is phosphorus.

You can already see it now.

Xia Hongsheng hurriedly asked people to splash water, and then scraped off those white things.

This is not white phosphorus.

This thing has to be distilled, and the powder formed by the condensation of its vapor is white phosphorus.

White phosphorus is not easy to preserve, so it must be soaked in water or buried in sand to isolate the air and lower the temperature to prevent it from spontaneously combusting.

On the city wall, there are people holding binoculars at all times, closely watching the Great Food Army outside.

The weather was hot, and the corpses floating on the water decomposed so quickly that people were disgusting, and for the time being, those things that were invisible to the human eye were all downstream with the water.

Only three days later, there was already a wide range of diarrhea in the Great Food Army. They don't have medicine, and even if they do, they don't care so much about taking it.

The disease spread rapidly, and even the simplest diarrhea was enough to make the soldiers who had eaten so much that they could not carry weapons or horses.

The lack of medicine and treatment makes the disease progresse very rapidly.

"Give me another order, the soldiers and people in the city hold out for a few more days, and never drink the river water!" Xia Hongsheng put down the binoculars and said to the soldiers beside him: "If you drink the river water by mistake, go to the military doctor immediately to get medicine." If you have diarrhea, you can't relieve yourself anywhere, you can only go to the river to solve it. ”

Su Dingfang stared at Xia Hongsheng with both eyes, as if he had seen a demon or a monster.

"Brother Sheng, I never knew that you still had such a side." Su Dingfang sighed.

Xia Hongsheng shook his head and took out a bottle, which was soaked in water.

"This thing, you're going to shoot it out later, whatever you want to shoot at any big cannibal." Xia Hongsheng handed it to Su Dingfang and said.

Su Dingfang fixed his eyes and looked at it, took out the feather arrow with his backhand, wrapped the thing around the arrow, and then opened his bow and arrow, and as soon as he let go, the feather arrow broke out of the air with a swish, and it was done in one go.

Xia Hongsheng gestured to Su Dingfang, and Su Dingfang understood, and immediately picked up the telescope and looked at it.

Over there, there was already a big cannibal who noticed it and went over to pick up the feather arrow.

Through the binoculars, Su Dingfang saw that the big food soldier took off the bottle, looked at it with the people around him, and then pulled the cork off the bottle.

The contents were poured out, and several people did not react.

One of the big cannibals reached over and pinched the contents.

Suddenly, I saw a flash of green light, a burst of smoke suddenly appeared, and the hand of the big eater soldier was actually on fire!

The great eater immediately pounced, trying to extinguish the fire in his hand, but he did not think that the green fire could not be extinguished, and it had been burning on his hand, and with his beating, it began to burn to other places on him!

He immediately rolled on the ground, but the green fire was even more violent, and thick white smoke came out, which choked several people around him with tears and couldn't get close.

The big eater screamed as he rolled on the sand. The green fire was always on him, burning the flesh and exposing the bones, but it burned more violently on the bones, and more choking white smoke came out.

The green fire was finally extinguished, and the big eater was no longer moving. The original white bones on his arm have been burned into black charcoal.

Su Dingfang put down the telescope and turned his head to look at Xia Hongsheng: "The name of this thing is white phosphorus, if it is exposed, it will spontaneously combust with a little friction, and the temperature is extremely high." And it is like a maggot on the tarsal bone, which is difficult to remove. Once it gets into the human body, it will keep drilling into the body, and after burning the skin and flesh, it will continue to burn the bones! In the next two days, when the epidemic in the Great Food Army was even worse, I threw the Heavenly Shaking Thunder and Medicine Packets containing this item into the Great Food Army with bows and arrows or stone throwers! ”

Su Dingfang listened to Xia Hongsheng's faint tone, but his heart was cold, and a chill appeared on his back.

"Brother Sheng, ...... you" Su Dingfang opened his mouth, as if he felt that Xia Hongsheng in front of him was a little strange and terrifying.

"Gewu is a thing that can benefit the people if it is put in the hands of good people, but if it is mastered by bad people, it will ruin the world." Xia Hongsheng shook his head: "I said a long time ago, if I am forced to be ruthless, then even I am afraid!" These big cannibals want to trap me here, how can they get their wish! ”
