Yang Fan returned to Nanyuan Military Camp and found a remote corner alone. Put a fire-proof zone around it and start studying the principles of napalm.
There are a lot of scrap tires here in Yangfan. They were all collected by idiots.
Most old tires can be retreaded by cutting them. Then these old tires will be given a new life on Daming's vehicles. A few that were seriously damaged, Yang Fan cleaned them and disposed of them with chips.
These rubber particles can be dissolved in gasoline and kerosene. This chemical phenomenon is called swelling, and it's how napalm is made. (The specific principles will not be described again).
With His Majesty's consent, Yang Fan has bought all the fire oil from the Ministry of Industry, totaling about two thousand tons. Refining is currently being stepped up.
Yang Fan did some calculations and found that he could probably refine 100 tons of gasoline and 200 tons of kerosene. Enough for this one time. First take out some of the gasoline to make an incendiary bomb.
Large incendiary bombs were used to burn city walls and gates. Small hand-held incendiary bombs used to burn grasslands.
It is impossible for the Ordos and Tumuts to spend the winter in the city. Most of them are concentrated in several winter camps. Generally, there will be a lot of dry grass in such places. It is convenient for livestock to dig out from under the snow with their hooves.
After Yang Fan prepared the gasoline bombs, he made them into small bottles. Let An Sanxi take the cavalry to burn their pastures and camps at night. It hasn't snowed this year, so I took the opportunity to burn all the dead grass.
Yang Fan's horse was good, and a small force attacked and set fire. They couldn't prevent it, and they couldn't catch up afterward. After a few times, they couldn't stay in the winter camp any longer. Yang Fan now has a large number of cavalry on the grassland, and he takes the opportunity to concentrate his forces to defeat these camps one by one and capture the herdsmen.
Yang Fan, the herdsman on the grassland, naturally wanted to accept it. As for the naturalized city, give it to the emperor.
Hearing Yang Fan's plan, Zhang Shize rubbed his teeth and said, "You are really wicked. You burned all the grass. Didn't you push them to a dead end?"
There are many windy days on the grassland this season, so just set fires every once in a while. When the time comes, the wildfires will start a prairie fire, and the Mongolians will have no choice but to run to other winter camps to take shelter. After they gathered themselves together, they happened to catch the turtle in the urn. No one can escape.
After a day of busy work, the first batch of napalm bombs was finally ready at three o'clock in the afternoon.
"Master, let's go test-fire quickly. I can't wait." Xiao Niangpi said happily.
Yang Fan was also speechless. The little girl really likes to play with fire, and she still doesn't change her infatuation even at this age. I wonder if my father spanked me when I was playing with fire when I was little.
Lin Yueru also had the same expression on her face.
Zhang Shize also urged: "Let me tell you, is it good or not? When it's ready, go and test-fire it. I've been busy with this thing for several days, and the waiting is very anxious."
Well, everyone is young and generally impatient.
"Let me first declare that this thing is extremely dangerous and cannot be tested here. You have to go to the island in the lake." Yang Fan said with a serious face.
"Master, why don't you hurry up and leave quickly?" Xiao Niangpi urged. This bitch, when she heard about the arson, her little face turned red with excitement.
Yang Fan leaned close to her ear and whispered: "Children who play with fire tend to wet the bed at night."
The angry girl stepped on Yang Fan's foot hard with her little leather boots.
Yang Fan ordered a group of engineers from the general flag to drive a steam engine boat. I found a small island in the largest lake in Nanyuan. Nail wooden stakes on the island and tie some pigs, sheep and other livestock.
"You all listen carefully, no one is allowed to get off the boat, just observe on the boat. Zhang Dali"
"Here we come," a burly man stood at attention and shouted.
"You put on your asbestos protective clothing and send a team to the island with a box. Follow my orders. Experiment with several types of incendiary bombs one by one."
"Here!"
A team of five engineers took a small boat to the island with several boxes of incendiary bombs. There is a tree in the center of the island, which grows very tall. Now in this season, the leaves have all fallen, it’s the time when the weather is dry and things are dry, so be careful with the candles.
It was the perfect time to set a fire, and now this tree was the target.
"Throw the Molotov cocktail, one shot." Yang Fan ordered.
One of the sappers picked up a glass bottle and threw it at the trunk of the tree.
Yang Fan's glass factory has started producing flat glass, and at the same time, trial production of cans, bottles and wine bottles has begun. Yang Fan has no shortage of glass bottles.
This glass bottle has a capacity of about 550ml, which is not large. It contained a solution of gasoline and rubber powder, with white phosphorus and white sugar added. The mouth of the bottle is stuck with a cork. And seal with glue.
There are many phosphate rocks in Daming and there is no shortage of phosphorus powder. These Molotov cocktails became the famous Molotov cocktails in later generations. An artifact that can even burn down tank engines.
White phosphorus has a very low ignition point and will spontaneously ignite if the bottle is broken. Then detonate the Molotov cocktail.
But it was winter and the temperature was very low, so Yang Fan installed a fire tube and a gunpowder bag in the middle of the cork. These combustion bottles are produced in underground ice cellars to ensure that they will not catch fire when white phosphorus is added.
After adding it, the air is immediately cut off. Therefore, as long as it is not broken or exposed to air, it will not catch fire during normal storage and transportation.
At this time, the engineer, protected by two other engineers holding shields, pulled a glass bottle and pulled the fire tube. It was thrown towards the dead tree.
boom! There was a sound, the gunpowder was ignited by the fire tube, and the bottle exploded.
A ball of flame suddenly shot out. Flames rose into the sky. Even though Yang Fan and the others were on the boat fifty meters away, they still felt the heat coming from the flames.
When the gunpowder exploded, they found that a large amount of viscous gasoline and rubber solution was blown everywhere. The droplets of solution fell there and ignited the surrounding dry grass. And then it keeps burning.
A large area of the island was a sea of fire. A large area of litter on the ground was ignited by the splashing napalm.
A few drops even flew onto the shields of the engineers, and these steel shields were also burning with flames. Seeing the flames on the shield, a soldier couldn't help but slap it with his sword in an attempt to put out the flames.
Just as Yang Fan was about to stop him, it was already too late.
As soon as the soldier slapped him, flames suddenly shot up and burned his arm. Fortunately, Yang Fan asked them to remove the asbestos protective clothing in advance.
"Don't beat him, lie down on the ground, and cover his sleeves with sand. Hurry." Yang Fan shouted hurriedly.
These engineers, who often handle explosives, were very calm at this time. Once they made a mistake, they would never make the same mistake again. The soldier whose arm was on fire was fine because he was wearing asbestos clothing. He immediately dropped to the ground and stretched his arms forward.
Several other people immediately picked up sand and covered his arms, and the fire was suppressed.
"Now listen to my order, slowly untie his asbestos clothes, and withdraw his arms from the clothes. Don't remove the soil that is pressed down. The sleeves will immediately rekindle if exposed to wind."
Zhang Shize, Xiao Niangpi, Lin Yueru and the engineers were all shocked to see what this was, as long as it got on it, it would keep burning. The soldier finally retreated safely.
His face turned pale with fright.
At this time, a gust of wind blew away some of the sand covering the clothes. Then, an orange-red flame burned again, looking like sand burning.
