"It's very simple, you only need to grasp the Monroe effect, simply put, the difference in the shape of the explosive column will have a huge impact on the explosion effect, usually, you can apply these formulas!" Shen Long took out his notebook and wrote several formulas on it with a pencil brush, "The first formula is ......"

Li Yunlong had never been cowardly when he met Guojun or a little devil before, but today, when he saw those book-like things in Shen Long's notebook, he couldn't help but open his mouth wide, and his head was dizzy for a while.

Later, when he was in the military academy, he could say, "I was a poor child when I was young, and I couldn't afford to go to school because my family was poor. It is because of poverty that we have revolutionized and rebelled, and the world is fought down by us uneducated mud legs! Chang Kaishen's general is educated, he goes to college and studies abroad, he is a, or is he not doing anything, and he was driven to the island by us mud legs? ”

But now he can't say this, because Shen Long has proved with actual cases that these formulas he wrote are effective, and only a little explosives were used to create such a big result, this thing is really useful, if the Eighth Route Army can master this technology, it will definitely save a lot of explosives.

But let Li Yunlong learn it, he pondered that he was afraid that he would not be able to learn it even if he suffocated his head, and he regretted a little that he had let Shen Long teach him.

Shen Long saw Li Yunlong's reaction, and deliberately said with a smile, "Leader, this thing is quite simple, I guess you can learn it after telling you a few times, come, let's look at this formula first......"

"Scholar, you wait a while, there seems to be some chaos ahead, I have to hurry up and command!" Li Yunlong pulled Zhao Gang over, "Since it's simple, then it's not much fun for me to learn, you better teach Lao Zhao." After speaking, Li Yunlong ran away, leaving only Shen Long and Zhao Gang standing here.

"This old Li! I just never like to learn! Looking at his back, Zhao Gang couldn't help but shake his head, Li Yunlong is good at everything, but he has a bad temper and doesn't like to study, he can't go on like this.

"Let me see the formula you wrote?" Zhao Gang is a top student of Yenching University, this simple formula can still be understood, after asking, Zhao Gang feels that this thing is still very useful, "You take some time to write a report in the evening, this kind of good thing should be promoted throughout the army, in two days I will draw some comrades with a better cultural foundation in the regiment, let them follow you to learn more, if this technology is promoted, how much explosives can we save!" ”

The Eighth Route Army's arms supply was not abundant in the first place, and if it learned this hand, it would be of much significance, and every time it was blasted, it would save a little bit, and the amount that hundreds of thousands of Eighth Route Army could save in a year was definitely not a small number.

"No problem, I'll go back and think about it and see if I can make the formula smooth or something, so that the big guys can understand it better!" The wisdom of the masses is infinite, during the Anti-Japanese War, the Eighth Route Army compiled a lot of combat skills into a smooth or folk song, so that it was widely circulated, Shen Long also listened to the mathematics teacher when he was studying, such as "odd change and even change, symbol look at the quadrant" and other smooth words, this advantage will not be forgotten.

"That's a good idea!" Zhao Gang now admires Shen Long more and more, he is both literate and down-to-earth, which is what our party intellectuals should look like.

The results of the first battle of Ping'an Grad were much greater than Li, more than 1,000 defenders in Ping'an County were all killed, the squadron from Taiyuan was completely annihilated by Chu Yunfei and the local armed forces, and the rest of the reinforcements from all walks of life also suffered more than half of the casualties, the Beitongpu Railway was destroyed into several sections, and the wired communication network of the Japanese army in the entire northwest area of Shanxi Province was completely destroyed.

What's worse is that because the arsenal was blown up by Shen Long, more than half of the senior generals of the First Army died, which caused the First Army to be unable to support the northwest of Jin in a short period of time, and the remaining little devils in the area also began to become uneasy, for fear that they would become the next target to be attacked.

The Eighth Route Army, the Jin Sui Army, and the anti-Japanese armed forces in the northwest of Shanxi Province were keenly aware of the weakness of the little devils, and they began to use various methods to attack and harass the nearby little devils, and the anti-Japanese armed forces in an area of more than 1,000 square kilometers entered the stage of strategic counteroffensive ahead of schedule.

However, what is encountered now is not all good things, the power of the little devils has retreated in the northwest of Jin, and there is a power gap in the local area, and it is not only the Eighth Route Army that fills this gap, if the Jin Sui army occupies these territories, it may be better to say, but let those bandits who have no bottom line occupy these territories, then the people around here are not much better than under the rule of the little devils.

It may even be worse, the number of little devils is small after all, even if they occupy a certain place, most of them stay in the county seat or military important places, and will not go to those remote villages, these bandits are different, don't look at some anti-Japanese dramas that describe bandits as thin and cloudy, but in fact, bandits are bandits, and the vast majority of bandits are not very friendly to the people.

They are fierce and irritable, cruel and irascible in nature, illiterate, have no faith, no political opinions, and are not even very clear about the distinction between likes and dislikes in general; They believe that in life, you can't come in vain, you have to enjoy happiness, you have wine, meat, women, and money to spend.

As for these from there, it is naturally from the hands of the common people to rob, a big bowl of wine and a large piece of meat, and then grab a woman to enjoy the candle night in the cave room, this day, to a fairy will not be changed.

In this context, Li Yunlong brought up the topic of bandits at the meeting of the Independent Regiment, "Lao Kong of the New Second Regiment seems to be co-opting bandits recently, and the big guys have all said, should our Independent Regiment do the same?" ”

Zhao Gang, Guan Dashan, Sun Bin and others spoke one after another, and their views were inconsistent, Zhao Gang believed that the anti-Japanese united front should be emphasized, and as long as those who were willing to contribute to the anti-Japanese struggle, they should be united; Sun Bin, on the other hand, thought that pulling these bandits into the independent regiment would ruin his reputation.

It was Shen Long's turn to speak, and he said, "I think we need to unite all groups that can be united, even bandits; However, for bandits like Liang Erhu in Heiyun Village, we not only can't unite, but we should even exterminate them! ”
