"Didn't I go to the border hospital before? No, I've brought you the root you've always wanted to see. Liu Lao said with a smile.

Director Cheng's eyes fell on Liu Gen, and obvious joy appeared on his face, he knew what Liu Lao had done in the border hospital. When Liu Lao came back last night, he didn't reveal any news, he thought that Liu Lao couldn't bring Liu Gen back, but now it seems that Liu Lao is really Liu Lao! Unexpectedly, he successfully brought back the genius Liu Gen!

"Hello Director Cheng!"

"Liu Gen, captain of the artillery team of the 129th Brigade of the 386th Division, came to report!" Liu Gen saluted with a serious expression!

Director Cheng stretched out his hand, looked at Liu Gen with some excitement, and after holding Liu Gen's hand hard, he said: "Captain Liu, you finally came to our arsenal, the 60mm mortar ** paper you took out before has done our arsenal a great favor!" All along, the arsenal wanted to build mortars, but it has never been able to capture the relevant drawings from the devils. ”

"The 60mm mortar you came up with is quite mature and saves a lot of time in the arsenal. It stands to reason that with the credit for your mortar ** paper, it should be praised by the whole army. It's just that you also know the special nature of our arsenal work, which makes it impossible to praise you for the whole army, but don't worry, I have already applied for credit for you from the headquarters, and it will be directly recorded in your file when the time comes. ”

“……”

Liu Gen felt the strength of Director Cheng's hand, he was a little surprised, he didn't expect Director Cheng to have such an attitude towards him, he was too enthusiastic. Liu Gen was a little ashamed, in his opinion, compared to the experts and workers of the arsenal, he did not do much.

"Okay, Xiao Cheng, calm down your emotions, Genzi was brought to the arsenal by me, and he will be a person from our arsenal in the future."

"This time I went to Genzi in person, and I saw another mortar ** paper designed by Genzi, which is very good, there is no problem with the data, and it is very mature. It only takes a few test shots to be manufactured, and it can be put into production on a large scale. This time, the mortar designed by Genzi is more suitable for our Eighth Route Army, and the cost will be much lower. Looking at Director Cheng who looked excited, Liu Lao said helplessly.

Liu Lao has always felt that Director Cheng is still very stable, and he has also done a very good job in handling the daily affairs of the arsenal, but today Director Cheng saw Liu Gen and was too excited. Liu Lao didn't understand why Director Cheng was so excited, Liu Gen was good, but there was still a lot of gap compared to Director Cheng.

Of course, Liu Lao can be sure that with Liu Lao's genius, he will definitely be able to grow up quickly in the future and become even better than Director Cheng.

"Did Captain Liu design another mortar?" Director Cheng calmed down a little, and there was not much excitement on his face.

The arsenal has been expanded to a certain extent, and now there are as many as three or four thousand workers in the arsenal, but because there are not enough lathes, most of the work such as the production of weapons and ammunition still needs to be polished by the workers. The 60mm mortar paper that Liu Gen took out before, after careful research and test firing in the arsenal, found that it was quite good, so the arsenal dispatched a lot of workers to manufacture and produce 60mm mortars.

However, even if the arsenal sent a lot of workers to produce 60mm mortars, the output was not much, and only less than ten could be produced per month. Now Liu Gen has designed a mortar again, but the arsenal is unable to draw too many workers, and with the 60mm mortar, unless it is a mortar with a larger caliber, there is no need to produce it at all.

Before Liu Gen didn't come up with a 60mm mortar, the arsenal tried to produce 50mm mortars, which naturally used the devil's grenadier as a reference object, but after seeing the 60mm mortar that Liu Gen took out, the arsenal focused on the production and manufacturing of 60mm mortars.

"Liu Lao, you also know the situation in the arsenal, in order to produce 60mm mortars, we have transferred a lot of workers, I am afraid that we will not be able to draw too many people into the production of new mortars." After a moment of silence, Director Cheng still spoke.

Liu Lao nodded, his face did not change much, he also had a job in the arsenal on weekdays, so he naturally knew the situation in the arsenal.

"Xiao Cheng, I understand your concerns, don't worry, this time the root design is an 82mm mortar, once it can be mass-produced, then it will further supplement and improve the firepower of our army." Liu Lao said with a smile.

Suddenly, Director Cheng was stunned, he thought that Liu Gen had designed a new 60mm mortar again. After all, Liu Gen has previous experience in designing 60mm mortars, and it will undoubtedly be quite easy to redesign a 60mm mortar. Now from Liu Lao's mouth, he heard that Liu Gen designed an 82mm caliber mortar, and he was quite surprised.

Designing a mortar is not so simple, it is easy to draw relevant drawings, the difficult thing is the relevant data, there is no accurate data, then the designed mortar is prone to all kinds of problems.

Liu Gen on the side watched the conversation between Liu Lao and Director Cheng, but he didn't have too many ideas, it was good to take out an 82mm caliber mortar, and in the process of drawing it, he also completely absorbed the knowledge and technology needed. Now even if Liu Gen is asked to redesign an 82mm mortar, there is no problem. But even if Liu Gen could redesign an 82mm mortar, he wouldn't do it.

After taking out the drawings of this 82mm caliber mortar, Liu Gen is not ready to waste too much energy on this mortar, everything only needs to be handed over to the relevant personnel of the arsenal to do, Liu Gen believes that with their technology, there will definitely be no problems. Instead of focusing on 82mm mortars, it is better to focus on gunpowder.

Due to the insufficient power of the gunpowder used in the arsenal, the bullets reloaded by the arsenal and the grenades manufactured were not very powerful. In Liu Gen's view, what the arsenal needs most is to update its gunpowder technology, rather than continue to use the old-fashioned black powder.

The use of old-fashioned black powder in the arsenal was also a helpless move, the Eighth Route Army did not have many talents in gunpowder, and there were not enough technical reserves in the base area to make more powerful gunpowder.

Of course, according to Liu Gen's understanding, all departments of the Eighth Route Army have tried to improve gunpowder, and have achieved a lot of results. Among them, the Jin-Cha-Ji Military Industry Department was able to produce sulfuric acid on a large scale in 40 years, and sulfuric acid is the basis for the manufacture of smokeless gunpowder and nitroglycerin and other high-grade explosives!

In terms of gunpowder research, the Shanxi-Chahar-Hebei Military Industry Department is undoubtedly at the forefront of the Eighth Route Army.

"Genzi, do you have drawings with mortars? Let me see. Director Cheng looked at Liu Gen and asked expectantly.

Liu Gen shook his head, the drawings were not with him, in order to ensure that there would be no problems with the drawings, Liu Lao put the drawings beside him,

Seeing Liu Gen shaking his head, Director Cheng was a little disappointed, he really wanted to see how the 82mm caliber mortar designed by Liu Gen was!

"Xiao Cheng, the drawings are here, you can take a look." Liu Lao said with a smile.
