Liu Xuan just wanted to break his head, and he couldn't understand what kind of time bomb was so awesome, it could be timed without an alarm clock, and when the bomb was sent to the Japanese patrol, they couldn't check that it was a time bomb.

So Liu Xuan secretly made up his mind that he must learn from Lin Jiangbei how to make this magical time bomb. As long as he mastered this magical method of time bombs, if he was faced with the task of blowing up Japanese warehouses and barracks and other military facilities in the future, wouldn't he be able to swagger and bring in the time bombs under the noses of the Japanese?

"Stationmaster Lin, isn't this method of making a time bomb very complicated? Will I be able to learn? However, Liu Xuan was still a little unconfident in his heart, and couldn't help but ask Lin Jiangbei.

"Hehe," Lin Jiangbei laughed again, glanced at Liu Xuan, and said, "Lao Liu, how can you say that you are also an excellent graduate of the Correction Department of Zhejiang Police Academy, why don't you even have this self-confidence?" The method of making this time bomb is not complicated, as long as there is a certain chemical basis and the time of the chemical reaction can be calculated according to the formula, it is basically fine! ”

Seeing that Liu Xuan's face was wrinkled into a bitter melon, Lin Jiangbei said again: "Is the chemical foundation not good?" ”

Liu Xuan nodded hurriedly and said: "My chemistry score is a little worse, and when it comes to the calculation of molecular formula and molecular weight, the brain will basically be broken." You said that if I calculate the time of the chemical reaction according to the formula, it is estimated that it is better to shoot me directly. ”

Lin Jiangbei nodded, but he was not very surprised. In this era, even if the Zhejiang Police Academy recruits students, there will not be too many outstanding chemistry scores, as long as the results in other subjects are excellent, they can still be admitted to the Zhejiang Police Academy Correction Class.

"If you don't get good grades in chemistry, you can't calculate the time of a chemical reaction according to a chemical formula, and it doesn't mean that you can't learn how to make a time bomb like mine." Lin Jiangbei pondered for a moment and said, "You only need to memorize the fixed ratio of all the ingredients in a few commonly used recipes." It's just that in this way, there will be a lot less flexibility, and when you encounter some special occasions and places that need to accurately calculate the detonation time of the time bomb and the amount of TNT explosives, it is estimated that you will not be able to prepare this kind of time bomb independently! ”

"Just remember a few common recipes!" Liu Xuan was very satisfied, "As for those special occasions, I will ask the stationmaster for advice then!" ”

"Hmmm! That's all it can be! Lin Jiangbei said, "You first look at my production process on the side, as for the ratio of various raw materials, you don't have to make a record, I will list a few commonly used fixed recipes for you at that time, you just keep it in mind!" ”

While speaking, Lin Jiangbei put the accurately weighed TNT explosives into the clay basin, and then lit the kerosene stove, and asked Liu Xuan to use the iron pot he had just bought to wash half a pot of water, and then sit on the kerosene stove.

Then Lin Jiangbei took advantage of this time to weigh a certain proportion of flour and several chemical reagents purchased from the chemical materials firm with a balance scale, and put them aside.

When the water was boiled by the kerosene stove, Lin Jiangbei measured a certain proportion of boiling water with a measuring cup and poured it into the TNT explosives in the clay pot. The melting point of TNT explosives is 82 degrees Celsius, and when 100 degrees of boiling water is poured on it, it immediately melts into a liquid.

At this time, Lin Jiangbei quickly picked up the flour placed aside and poured it into the clay pot, and then picked up a short wooden stick and stirred it quickly. After the flour was completely fused with the TNT explosives that had melted into a liquid, Lin Jiangbei added several chemical reagents placed on the side to the mixture of TNT explosives and flour in turn, and through the stirring of short wooden sticks, these chemical reagents were evenly mixed with the mixture of TNT explosives and flour.

Then, when the temperature in the clay pot cools down, there is a yellow, elastic soft dough left.

Liu Xuan became more and more confused the more he looked at it, and he had a stomach full of questions that he wanted to ask Lin Jiangbei, but he was afraid that he would take the liberty of asking and interrupt Lin Jiangbei's production process. It was easy to wait until Lin Jiangbei stopped, and then he hesitated to point to the soft dough of the clay basin and asked Lin Jiangbei: "Stationmaster Lin, are you really making a time bomb?" Why do I look like I make dough cakes? ”

Lin Jiangbei nodded and said, "Lao Liu, what you said is right, you are making dough cakes." ”

"What, it's really a dough cake!" Liu Xuan couldn't help but be dumbfounded.

Lin Jiangbei couldn't help laughing, and said to Liu Xuan: "However, the dough cake I made can also be used as a bomb!" ”

"You mean, this thing can be used as a dough cake as well as a bomb?" Liu Xuan hurriedly asked, "Could it be that the stuff is really edible?" ”

"Of course you can eat it, but the taste is slightly worse than the normal dough cake!" Lin Jiangbei gestured to Liu Xuan, then pointed to the iron pot next to him with his finger, and said, "We just need to make this dough into a dough with our hands and cook it in the iron pot!" ”

While speaking, Lin Jiangbei poured out the remaining water in the iron pot, and then adjusted the heat of the kerosene stove to a low state and put the iron pot on it.

Taking advantage of the fact that the water in the iron pot was dried by the fire, Lin Jiangbei divided the soft dough in the clay pot into two, and then put it on both ends of the balance scale to adjust, knowing that the weight of the two pieces of soft dough was completely equal, he stopped, took out the two pieces of soft dough, and kneaded the two pieces of soft dough into two bowl-sized cakes with the palm of his hand.

Lin Jiangbei turned his head to look into the iron pot and saw that the water inside had been completely roasted. So he dipped his hand in a little water, and then with a flick of his fingers, he saw a few drops of water fall into the iron pot, hissing sound, and quickly boiling.

"Lao Liu, you must remember this process." Lin Jiangbei pointed to the iron pot with his hand and said to Liu Xuan: "That is to say, at that time, the water droplets dripped on the bottom of the iron pot, and the water droplets hissed and boiled rapidly, and the temperature of the iron pot was basically slightly higher than 100 degrees, which is the best temperature for the pancakes!" ”

While talking, Lin Jiangbei took two soft dough cakes and pasted them on the bottom of the iron pot.

"No, wait a minute!" Liu Xuan hurriedly stopped Lin Jiangbei with both hands, and the cold sweat on his forehead came out, "Stationmaster Lin, are you sure that if you use an iron pot to brand this thing, there will be no explosion?" ”

Although Liu Xuan's chemistry foundation is not very good, when he was studying at the Zhejiang Police Academy, he also listened to the instructor explain the power of TNT explosives. It is known that once the 50 grams of TNT explosives explode, the radius of destruction is between 8 and 10 meters.

And the two soft dough cakes in Lin Jiangbei's hand happened to be mixed with fifty grams of TNT explosives, which means that once these two soft dough cakes exploded, at least Lin Jiangbei's room didn't think that any creatures could survive!

PS: Regarding the production method of the alarm clock time bomb taught by the Zhejiang Police Academy, it is not a fiction of the author, but a real teaching material from the Zhejiang Police Academy.

As for the time bomb made by Lin Jiangbei, it is also not a fiction of the author, but the bomb is partly derived from a variant of a bomb called "Aunt Jemima" used by the US military in the Burma battlefield in 1942. As for the timer, it is derived from a special incendiary bomb used by the German army during World War I. Then it was carried forward by the U.S. military during World War II.
