Fang Yuan opened the almighty Taobao system.

He was at least a 211 bachelor's degree graduate before he crossed over, and although he did not work in chemical engineering, his basic knowledge of chemistry was quite solid.

In a rain battle, it will not only affect the shooting of the Thunderbolt, but also the power of the artillery. The gunpowder and lead bullets of artillery are not easy to explode in rainy days, and even if they can explode occasionally, their power will be greatly reduced.

However, some industrial chemicals will produce a strong explosion when exposed to water, such as industrial metal sodium, such as calcium carbide, such as lithium metal, these highly active metals will produce a strong explosion when exposed to water.

After a large amount of sodium metal explodes in water, with the help of the combustible property of kerosene, it is enough to form a sea of fire on the water surface and the ground, and the fire of this kerosene is by no means extinguished by rain, and it will not be extinguished until it is burned out;

For example, calcium carbide will produce explosive gas acetylene when exposed to water, resulting in deflagration;

Another example is lithium metal, which will not only explode when exposed to water, but also produce a large amount of hydrogen, and the density of hydrogen per unit space reaches a certain concentration.

Fang Yuan's idea was to purchase a large number of these three industrial metals on the Taobao system, and mix them on the battlefield by the drone team, and the power generated was enough to match the artillery of the artillery battalion, completely destroying the combat power and fighting spirit of this gangster.

The most important thing is that the price of these industrial metals is not expensive, and it does not cost much silver to buy a few tons, in fact, it is much lower than the cost of artillery warfare.

Liangshan Liukou wanted to fight on a rainy day, but he miscalculated, because Fang Yuan wanted to fight in the rain more than them.

Fang Yuan carefully compared the quotations of sodium metal, calcium carbide and lithium metal on Taobao, of which sodium metal is about 25,000 yuan/ton, lithium metal is 130,000 yuan/ton, and calcium carbide is 3,000 yuan/ton.

The cost of lithium metal was too high, so Fang Yuan chose to give up;

The reaction of sodium metal with water can produce sodium hydroxide and hydrogen, and the price is several times lower;

The reaction of calcium carbide with water can generate the deflagration gas acetylene, and the price is still the price of cabbage, which is naturally the first choice.

Fang Yuan thought about it for half an hour and decided to buy one ton of metal sodium and five tons of calcium carbide for this operation to exterminate the Liukou.

The current drone team only has twenty drones, and in order to achieve the effect of deterring the rogues, Fang Yuan gritted his teeth ruthlessly, and spent 50,000 taels of silver to buy thirty of the latest waterproof drones, making up the team establishment of fifty units.

The UAV has a loading capacity of about 20KG, and it can throw a ton of metal sodium or calcium carbide when it strikes once.

Fang Yuan could almost imagine such a huge drone team, overwhelmingly killing the Liangshan Rogue, this group of Rogues was terrified.

He negotiated with chemical distributors selling sodium metal and calcium carbide on Taobao to disperse one ton of metal sodium metal into 10KG of metal sodium and 10KG of kerosene, mixed into a tin keg, and shipped it in a total of 100 barrels.

Fang Yuan's purchase amount this time was only about 40,000 yuan, which was a small customer among the customers of industrial product procurement, but the merchant was reluctant to put forward such a complex packaging requirement.

In desperation, Fang Yuan could only pay an additional 5,000 yuan for packaging, and the merchant agreed to deliver the goods according to his packaging requirements.

Fang Yuan had 53,000 yuan in the system's voucher, plus the purchase of 30 drones, the merchant gave away 30,000 yuan in vouchers again, and the system's voucher had 83,000 yuan.

He used a voucher of 45,000 yuan to pay for the purchase of chemical metals, and he did not spend a tael of silver on the freight. He estimated that the profiteer system would be so angry that he would blow his beard and stare at him if he didn't receive his freight, but the loopholes in the system's rules were not drilled in vain.

The next day, Chigutai led his army to the front to destroy the bridge, and also went to set up simple fortifications on the battlefield that Fang Yuan had preset.

Li Zongze's artillery battalion loaded dozens of artillery pieces onto the ship, and in accordance with Fang Yuan's instructions, more than a dozen leased merchant ships accelerated their way in the canal to leave the battlefield as soon as possible.

Fang Yuan and his party traveled all the way south, and at dusk, the metal sodium of 100 small iron barrels he bought, as well as five tons of calcium carbide packed in large iron barrels, finally arrived.

These industrial metals are all flammable and explosive, and Fang Yuan was stored with extra care, so that people put on a special rain-proof and moisture-proof linen cloth on the ox cart for transportation, and wrapped it in several layers.

Jing Jie and Su Hongyu looked at the hundred iron cylinders in front of them in amazement, completely unaware of what Fang Yuan was doing.

Fang Yuan asked people to take out a small iron keg and open the lid, revealing the metal sodium soaked in kerosene.

Kerosene is fire oil, this taste, Jing Jie still knows, but in the kerosene, a piece of black silver-white, like enough metal sodium in silver bars, but I don't know what it is.

Fang Yuan ordered the sergeant to carry a small 20KG iron bucket and 10KG of calcium carbide to the river with the two, and directly ordered the sergeant to pour the metal sodium and kerosene in the iron bucket into the canal.

As soon as the 10KG metal sodium touched the water, it immediately reacted violently and emitted white smoke.

"Boom!"

The sodium metal made a loud noise, and there was a violent explosion, and the explosion caused a huge splash of water.

Then the flames erupted, and the fire met the floating kerosene on the water, and burned on the surface of the water, like a fire dragon rising and dancing on the surface of the canal.

Fang Yuan ordered the sergeant to throw the calcium carbide down again, and the burning fire dragon rose into the air, and the fire became more and more intense.

"Boom, boom!"

The full reaction of sodium metal, calcium carbide and water produces a large amount of hydrogen, and the concentration of hydrogen rises sharply, and then encounters a raging flame, which immediately triggers a more violent explosion.

A deafening sound sounded, and a splash of water mixed with fire oil was thrown, pouring Fang Yuan and a few people not far from the shore into soup chickens.

A sergeant was so frightened by the sparks that he set his clothes on fire and hurriedly extinguished them with sackcloth.

Fang Yuan and the others retreated ten zhang to avoid being affected by the firelight.

The explosion on the surface of the river continued, and it was only after a few sounds that it gradually weakened and disappeared without a trace.

Jing Jie and Su Hongyu were dumbfounded, kerosene and silver bars could burn automatically in water, and it was the first time they had seen it.

Such a terrifying explosion is even more unheard of by them, and the shells of the so-called Hongyi cannon do not have such a big explosive power. This is simply equivalent to dozens of Hongyi cannons that can fire in the rain at the same time, and the power is so great that I don't want to know it.

Su Hongyu was stunned and asked, "Boss, what kind of magic is this?!" ”

Fang Yuan didn't have time to popularize chemical knowledge with them for the time being, so he simply explained, "This is not witchcraft, but this special silver bar will explode and burn when it encounters water, if it is a rainy day, use a drone to throw this kind of silver bar mixed with fire oil, is there a chance of winning?" ”

When Su Hongyu saw this powerful explosion and burning, she was naturally full of confidence, and said happily, "Boss, of course you are completely sure!" ”

Jing Jie is a veteran of the battlefield, and he can see the victory or defeat of the battlefield at a glance, if he throws it on the attacking rogue with a drone team, there is no doubt that it will be a one-sided slaughter.

He knew that he had been against Fang Yuan because his knowledge was too shallow, and he felt a deep guilt, "Boss, I ...... that day"

Fang Yuan stopped what he was talking about, and said with a smile, "Third brother, I may also have something I can't think about, I still have to say what I should say in the future, the so-called listening is clear!" Right! ”
