Anti-japanese War: I, Li Yunlong, Served the Militia

　　Build a simple housing near the copper ore, and equip two squads of troops to perform mining escort missions.

　　In order to make the goal not so obvious, copper ore will only be transported once when it has accumulated to a certain level.

　　That's it, after planning everything.

　　The resources of the ore began to be transported to Jinji Town in an orderly manner. .

Chapter 23

　　In the production furnace, the ore is put into the smelting together to get the required metal products.

　　Lu Chen didn't want to delve into the complex reaction process during this period. He had to ask the inventor of the production line for the design of the cartridge case and the production line for the grenade case.

　　Lu Chen only knew that by putting ore into the bullet production line, he could produce bullet casings.

　　Putting the ore resources into the grenade production line according to the stated proportion can produce the grenade metal casing.

　　It's that simple.

　　After a few simple operations, the team members of the 'sand cave' arsenal learned the operation steps.

　　They also didn't know anything about the operation of this modern machine, and they were even a little clumsy at first.

　　But once you get the hang of it, muscle memory is formed.

　　Production efficiency can be rapidly improved.

　　Lu Chen made a careful calculation. With sufficient resources, and with maximum power processing, the 'Cavern' arsenal can produce about [-] rounds of bullets a day.

　　Grenades can be produced between one hundred and six hundred (depending on the type of grenade).

　　And these three mines can keep the arsenal at maximum power production for three months.

　　Therefore, Lu Chen was not in a hurry to control the resources of the metal mine, but instead focused on the gunpowder resources.

　　As we all know, the production of gunpowder requires three important raw materials.

　　Nitrate, Sulphur and Charcoal.

　　Nitrate and sulfur ore are easy to find and relatively easy to extract.

　　Charcoal material can be obtained by burning wood, and after careful processing, the required 'carbon' can be obtained.

　　Lu Chen also has the proportional formula, which was brought from the border area.

　　First, he matched the gunpowder on the bullet.

　　According to the proportions, the launch gunpowder and the easy-to-burn primer yellow gunpowder are arranged.

　　The experiment was very successful, and it took less than ten attempts to produce the ideal state of the gunpowder.

　　The power of the bullets produced is not sure how much stronger than the ones made in the border area.

　　After completing a series of projects for the bullet, the next step is the grenade.

　　The craft of making grenades is much more complicated than bullets, and the metal casing is easier.

　　But this gunpowder ratio is quite complicated.

　　It also involves the issue of lead material, and the power of the explosive must be large enough.

　　In this way, the power of the shock wave will be large, and the damage caused by blasting the metal into fragments will be sufficient.

　　The proportion of gunpowder and the location of filling are also particular.

　　Lu Chen researched and made according to the drawings brought back by the border area, only to find out later...

　　The production content on the drawings is incomplete and quite imperfect.

　　"It's no wonder that after filling so many times with materials, it did not achieve the expected power of the grenade."

　　"Good guy, it turned out to be the problem with this drawing."

　　Naturally, what Lu Chen developed was not a hand-made grenade in the border area, but a grenade suitable for the production line.

　　Through the study of the little devil's cantaloupe grenade, plus the combination of the large tumor made by the German army.

　　Create a half-grip high-efficiency grenade, its lethality is at least ten times that of the frontier.

　　But the idea is good, but the reality still gave Lu Chen a heavy blow.

　　Not to mention that this drawing is imperfect, even if it is a perfect drawing, it is not an easy thing to integrate and develop.

　　"Hey, are so many days of effort in vain?"

　　Lu Chen was a little unwilling, leaning on the stone wall in the arsenal, sinking his mind.

　　"System, is there a way to solve the problem of grenade powder adaptation?"

　　'Ding Dong, the host can exchange for a solution by checking in for one day. '

　　Lu Chen frowned: "One day's check-in in exchange for a solution? What do you mean?"

　　'It means that the check-in is voided on this day in exchange for a solution. The more days accumulated, the better the solution can be obtained. '

　　Hearing the system's answer, Lu Chen took a deep breath, "Is this still possible?"

　　He thought about it, and he has been staying in Jinji Town recently, and the products that he signs in every day are those very common everyday items.

　　Now that the militia brigade is very rich, these items are a bit tasteless anyway.

　　It is not a loss to be able to exchange it for a solution!

　　Lu Chen: "Okay, then how many days will it take to sign in to exchange for the successful development of ten times the efficiency of the grenade?"

　　'Ding, ten times is five days, and twenty times is ten days. '

　　"Twenty times, and twenty times more?"

　　'Yes, the best solution given by the system can make the grenade produced under this production line obtain twenty times the power of the hand grenade made in the border area. '

　　The system's answer surprised Lu Chen greatly.

　　Knowing that he had this function, he asked earlier. If it was a key area to sign for a replacement, Lu Chen would be reluctant.

　　But now the sign-in in Jinji Town, the ten-day sign-in exchange for a super-efficient grenade with energy production, this is definitely a bloody profit!

　　'System, give me a twenty times the best solution! '

　　Lu Chen no longer hesitated and chose twenty times more efficient grenades!

　　'Ding, the system is being adapted, the system is successfully adapted, and a detailed matching plan for efficient grenades has been obtained. '.

Chapter 24

　　After the system's beeping sound ended, the blueprint that Lu Chen was holding in his hand seemed to have been 'changed'.

　　The detailed filling plan of various resource items is marked above, and the order of feeding is also specified.

　　Seeing this, Lu Chen's mouth curled into a smile.

　　Then, holding the military blueprint tightly in his hand, he came to the production team and said.

　　"Come on, listen to me, next, let's try this ratio..."

　　Lu Chen instructed the members of the production team to make according to the drawings, which took less than two hours.

　　The first batch of grenades was made. Lu Chen packed a box of grenades and called Wang Chengzhu.

　　"Pillar!"

　　"To!"

　　"Choose a few good grenade-throwing fighters from your artillery squad and follow me to test the trenches."

　　"Yes!"

　　Soon, on an uneven ground at the back of the town, a team of about ten people was already lined up, and they were well-trained in their positions.

　　Three strange-looking grenades were placed on the ground under their feet.

　　It was a grenade they had never seen before.

　　There were ten bamboo baskets about fifty meters in front of them.

　　Wang Chengzhu stood at the front left of the team with a serious face.

　　"This time the captain came to us to test our usual training results."

　　"I've praised you all so much, so don't embarrass me at that time."

　　"Each of you has a total of three chances to hit the basket in front of you, eat meat and drink at night, and if you don't hit, hum, you can do it yourself!"

　　Hearing Wang Chengzhu's words, the team members looked at each other and frowned slightly.

　　Fifty meters, such a small bamboo basket, this is much more difficult than their usual training.

　　Usually they practice throwing [-] meters, [-] meters and [-] meters.

　　[-] meters is not bad, the hit rate is basically more than [-]%, but the farther the distance, the lower the hit rate will be.

　　Especially at a distance of [-] meters, let alone throwing it into the bamboo basket, it is difficult to touch the bamboo basket.

　　It's not that their accuracy is not enough, but that there are many uncontrollable factors in the air when the grenade is far away, and many mines will be thrown too hard because of the force.

　　Change the offset arc position in the air, the left and right deviation is large.

　　During normal training, with a handle made in the border area, at a distance of [-] meters, it is not bad to be able to throw in once five or six times.

　　And now you have to throw in once after three throws, which is not a big requirement!

　　It was rare for them to look at each other, but in the end they quickly adjusted their status, picked up the grenade on the ground, and threw it forward!

　　When picking up the grenade, to everyone's surprise, this not-so-good-looking grenade felt surprisingly good.

　　And in the hand, the strength of the control is very good!

　　"Whoa, whoa, whoa~!"

　　They threw the grenade out, and the grenade drew arcs in the air.
