After finishing the miners' affairs, Liu Hua's eyes were fixed on the arsenal in Houshan, and the next day, Liu Hua came to Houshan with more than 100 arsenal workers personally selected by Liu Bo, the director of the factory. Entering the heavily guarded Woniu Cave, the first thing that catches you is the renovated arsenal site, the already smooth cave has become even smoother, and all the equipment and diesel fuel transported back from the coal mine are piled up in the corner next to the site.

Seeing the equipment, the scholars who were rescued from the devil mining area were obviously stunned, and then their eyes lit up, "Director Liu, the matter of the arsenal will be handed over to you, the task of the arsenal in the past two days is to rely on the existing equipment as much as possible to assemble a machine tool, which can be used to reload bullets and shells, and there is a mine inside that has a large amount of black powder that we have collected during this time, but the gunpowder used in bullets and shells needs to be studied by a few of you chemical personnel, and what raw materials are needed." We will be satisfied. Looking at everyone's expectant eyes, Liu Hua said.

"Brigade commander, rest assured, I know all this equipment, and I am confident that I can use this equipment to assemble a machine tool and some other spare equipment." Liu Bo swore an oath.

After speaking, he ordered his soldiers to start carrying equipment, and those scholars were on the side for technical guidance, looking at the hot workers, Liu Hua smiled, the problem that had been plaguing his arsenal was finally solved, then the first thing that came into view was a kind of bombardment cannon modified by gasoline barrels used by the People's Liberation Army at that time, if there was such a cannon, then in the future ambush war, their advantage will be greater.

Liu Hua thought with great expectations, came to a slightly quieter place, and began to draw a sample of the thunder according to the memories of his later generations.

Director Liu really didn't say much, after several hours of fighting, a machine tool was placed next to the site, and the other side folded a few small equipment, all the equipment was driven by a high-power generator, and the other was used as a backup, Liu Hua couldn't believe the several equipment in front of him.

"Director Liu, so fast, you really have you. The communicator, tell the cooking class, just say what I said, improve the food in the arsenal at noon today, kill a fat pig, and celebrate. Liu Hua said excitedly.

"Brigade commander, this equipment in the middle, that is, the machine tool, can be carried out" The factory director next to him introduced the efficacy of several pieces of equipment to Liu Hua one by one, through understanding, these pieces of equipment can not only reload bullets, but even artillery shells, if conditions permit, even produce bullets and grenades

"Director Liu, thank you, I will ask for credit for you, everyone has a good rest and a good meal at noon today, and all the staff of the arsenal will have a holiday in the afternoon." Liu Hua said loudly. After listening to Liu Hua's words, those employees immediately jumped up excitedly.

After lunch, Liu Hua called Liu Bo, who had already eaten and drunk, and the deputy factory director. "Director Liu, take a look at this drawing and see if the arsenal can be copied." Liu Hua handed the drawings he had spent all morning to Liu Bo, who was inexplicable next to him.

Liu Bo turned out the drawings and looked at them seriously with his partner. "Boom! Brigade commander, is this a cannon? Liu Bo looked at the three words on the drawing and the sketch below and asked suspiciously.

"Hehe, Director Liu, this can also be said to be a cannon, or it can be said to be a dropper, think about it, if you bury this cylinder in the ground, load it with a propellant bag, and install an explosive bag as thick as the barrel, so can't you throw the explosive bag, such a big explosive bag, if you run to the devil's position, then the devil in a radius of dozens of meters is still alive?" Liu Hua briefly introduced the thunder to the two.

"Brigade commander, this method is feasible in principle, let's go, now there are two empty oil drums in the warehouse, let's try it." Liu Bo was impatient and wanted to rush out the door.

"Hey, wait, Director Liu, don't worry. Today, you are precisely calculating the ratio of the amount of ammunition used to the weight of the explosives package, and for our own safety and other factors, the range of our thunderbolt must be at least 200 meters. Liu Hua hurriedly pulled Liu Bo, who wanted to go out, and said.

After listening to Liu Hua's words, the two did not stop, "Brigade Commander, you are going to kill us in a hurry, don't worry, we all remember." As he spoke, he shook off Liu Hua's hand and walked towards the factory, calling a few of his students by the way...... Looking at Liu Bo's appearance, Liu Hua shook his head, this really looks like a desperate San Lang.

The next day, before Liu Hua got up, he was woken up by the noise outside, and when he walked out of his house, Liu Hua saw that his guard was arguing with a soldier. Liu Hua put on a coat of captured devils and walked over.

"Xiao Wang, what's wrong, this comrade, is there anything wrong?" Liu Hua walked up to the two of them and asked.

Seeing Liu Hua who woke up, the guard named Xiao Wang breathed a sigh of relief: "Brigade commander, this comrade said that he was from the arsenal and wanted to find you, I saw that you hadn't gotten up yet, so I stopped it, and then" After speaking, he lowered his head embarrassedly.

"Nonsense, if there is something urgent, then it will delay the fighter, and if there is such a situation in the future, no matter what I am doing, I must tell me as soon as possible." After listening to the guard's words, Liu Hua knew that the guard was for his good, but he still criticized him harshly. After saying that, he turned to the fighter next to him.

"Comrade, is there something happening in the arsenal so early?" Liu Hua asked.

"Report to the brigade commander, Factory Director Liu let me tell you, the thunder has succeeded?" The warrior said excitedly, his face flushed.

"What, you said that the thunder was successful, go, go, go to the arsenal, Xiao Wang, immediately call the political commissar, chief of staff, go to the arsenal." When Liu Hua heard the good news, he excitedly threw down his coat and walked towards the arsenal.

"Brigade commander, brigade commander, the soldier in your clothes arsenal took Liu Hua's coat off and shouted loudly behind him.

Soon, Liu Hua came to the arsenal, Liu Bo was waiting at the entrance of the cave with a few technicians, it was obvious that these people did not sleep at night, and each of them had a pair of black eyes. "Report to the brigade commander, the Thunder Arsenal has been produced and is preparing for a test launch."

Looking at Liu Bo with black circles in front of him, Liu Hua did not speak, and saluted a solemn military salute to several people. "Comrades, you are all doing well." After speaking, under the leadership of Liu Bo, Liu Hua entered the arsenal and saw from a distance that an oblique gasoline drum was placed in the open space, reinforced with iron wire next to it, and a wooden bracket was used below, which was also reinforced with a certain amount of iron wire. Several explosive packets were placed next to the gasoline drums. Looking at the polished gasoline barrel, Liu Hua nodded with satisfaction. At this moment, the commissars and chiefs of staff came to the arsenal one after another.

"Commissar, chief of staff, you are here, today I want to show you a good show." Liu Hua saw the two partners who were flushed because of the hurry, and said with a smile, "Comrades, let's go." After saying that, several soldiers from the arsenal lifted the gasoline canister and the explosive bag next to it and walked towards a mountain area in the back mountain under the puzzled eyes of everyone, at this time, this mountain area had been completely blocked.

Looking at the heavily guarded mountainous area, the political commissar and others were even more anxious and puzzled. Seeing everyone's puzzled eyes, Liu Hua and Director Liu and others smiled and said nothing.

When he came to the venue, Liu Hua led everyone into the temporary bunker, picked up the binoculars, and saw several soldiers in the distance laying thunder. "Report to the chiefs, the thunder has been prepared and can be test-fired!" A technician ran to the bunker and said.

"Okay, test shot." Liu Hua gave the order, and his eyes kept staring at the muzzle of the cannon in the distance.

I saw that after several soldiers lit the fuse, they quickly ran away, and the flashing sparks slowly approached the oil drum, and at the same time, Liu Hua's heart was also raised, and the whole bunker was silent

An explosion reached everyone's ears, and a round thing was soaked into the sky. "Boom" Another powerful explosion reached everyone's ears, and the soil next to the bunker was shaken and fell one after another.

"Success, success, the arsenal personnel behind Liu Hua swept away the tiredness just now, roared loudly, and ran towards the explosion point one by one.

"Brigade commander, this is" The political commissar looked at the explosion point of the explosive package in front of him in a daze, only to see that a one-meter-deep crater had been blown out of the center of the explosion, and the grass with a radius of 30 meters next to it had almost been turned over, and it was black everywhere.

Seeing the scene in front of him, Liu Hua nodded with satisfaction. "Political commissar, chief of staff, this is the thunder that the arsenal has just developed, how is it, the effect is good, right?" Liu Hua said with a smile.

"It's not bad, if a shell hits a devil's squad, this squad will all die, it's just too powerful." The chief of staff next to him also nodded and agreed with the commissar's words.

"Director Liu, tell the political commissar and the chief of staff about this thunder!" Liu Hua found Liu Bo, who was measuring data, and said.

"Political commissar, chief of staff, this thunderbolt is designed and manufactured according to the drawings given to us by the brigade commander, his effective range is 200 meters to 500 meters, and the error just now is 6 meters, but as far as the power of the thunderbolt is concerned, such an error does not affect his power at all, he can launch 10 kilograms, 15 kilograms, 20 kilograms of three explosive packages, the power is very powerful, but he has a drawback, according to our calculations, after a launcher is set 50 times, it can no longer be used, and must be returned to the factory for re-reinforcement."

"That's enough, that's enough, Director Liu, I really didn't expect that you just joined the Eighth Route Army and made great achievements. What about the current production? The commissar asked excitedly.

"Hehe, political commissar, as long as there are raw materials, you can produce as much as you want? According to the original base area's black powder reserves, a total of 400 rounds of various ammunition can be produced, and after those diesel fuel are transferred, a total of 8 thunderbolts can be produced. Liu Bo thought for a while and said.

"Okay, Director Liu, the task of the arsenal in the near future is to produce thunderstorms, but the development and production of yellow explosives must not be put down, and manpower must be strengthened." Liu Hua said excitedly.
