Start early, be greedy for black, and at the end of the day, you can cast more than 800,000 arrow clusters!

Cui Qing felt that he was going crazy, and the hard work of the Dingxi Army Craftsman Battalion all year round was only more than 300,000 arrows. Year after year, careful use has accumulated today's family foundation, which is only two million branches.

Three days, just three days! can be more than 30 years of accumulation?

Three days is naturally absolutely impossible, even if all the craftsmen put down all the work in their hands and keep casting sand molds day and night, they can't turn over much in a day. What's more, there was no sand mold with arrow clusters before, and it was necessary to re-turn the sand and set it. Due to the sand mold of the first arrow cluster, the proficiency is naturally not high.

As a result, Renault had to find another way for the sand mold, which was a real headache, and Renault sighed again that invention and creation are really not human work.

It's not that Renault is lazy, he has to make this decision in order to rush the work, and a rough and outrageous mold way appears.

Eight craftsmen carry the plank, the arrow cluster is downward, and at the same time press down hard until the board is level with the sand, and then slowly lift the plank.

This is the compression molding method, the technology is not up to standard, do not try this way of molding, the final cast workpiece, 100% defective products, or even scrap products.

Fortunately, this time it is the arrow cluster to be cast, and Da Chu is still using the leaf flat arrow cluster, and Renault has the courage to use this method to cast the mold, if it is a triangle and prismatic arrow cluster that is more powerful, this method will not be used at all.

The benefits of the stamper method are also obvious, as long as the sand is flattened, a board goes down, at least fifty, and more can reach five hundred, Renault chose a relatively safe three hundred stampers, that is, press it, and produce three hundred arrow clusters of sand molds.

This method of mold making is very fast, hundreds of people work together, at the end of a day, can suppress more than 1,000 groups, easily suppress 300,000 sand molds.

In fact, it is completely possible to send more manpower, but Sun Lei is suspicious of Cui Qing's words, and he is unwilling to send more manpower, seeing that the war is getting bigger and bigger, and military funds are needed everywhere, so he can't mess around.

When he saw the 300,000 arrow patterns, the whole person was stupid, how could it be so fast?

The next day, the number of people used was obviously doubled, and the furnace was all vacated, iron ingots were put in, and after waiting for the liquid, Renault was invited.

Fortuna analyzes the content of molten iron and increases the carbon content, which does not need to be too good, as long as it meets the standard of steel. At the sound of an order, the molten iron was boiling, and a team of coolies, holding long-handled iron spoons in both hands, carefully poured spoons into the sand mold.

The large furnace is different from the medium furnace, it weighs 200 catties, and it is not possible to pour it by manpower, and the sand mold is too small to be watered with a spoon.

The arrow cluster cooled down slightly, put it into the urine and put it into the pure fire, and then put it into cold water to wash it off, Sun Lei took an arrow cluster, and he didn't know what to say.

The cast arrow cluster is obviously a lot rougher, far less fine than the hand-forged one, but it is indeed an arrow cluster, and the material is surprisingly good, this is fine iron.

Renault didn't care about the question marks in his head, and with an order, Cui Qing commanded everyone and brought a hundred manpower sand wheels. It is said that it is a sand wheel, in order to save time, no matter what shape the grinding stone is, it is directly punched and fixed on the pinion.

The coolie shook the handle, the big gear drove the small pinion, and the small gear drove the grinding stone, and it turned quickly. Cui Qing took a cluster of arrows with his own hands, clamped it with an iron clamp, and carefully stretched it to the edge of the grinding stone to find a good angle.

In the shrill sound of 'Zilala'......', sparks flew and the rough edges were worn away, and the blades of the arrows on both sides became sharp.

It only takes a few dozen breaths of work before and after, and an arrow cluster is finished, if you are willing to put some effort into grinding, the arrow cluster you get will not be much worse than the forged one.

Installed on the shaft of the arrow, the sergeant tried to shoot, and the arrow cluster easily shot through the bamboo armor, and even the leather armor could not block it. Before the Great Chu arrow cluster, the second-class iron material was used, the first-class iron material naturally had to be built into the armor, the second-class iron material was under the strong bow, and the bamboo armor could be broken, and the ordinary two-stone bow depended on luck.

If you shoot in the gap of the armor, it is normal to shoot someone to death, if you shoot on the bamboo armor, it depends on luck, as for the leather armor, it can hurt people at most, and it is almost impossible to shoot directly.

The cluster of arrows cast by Renault is a little rougher, and the available materials are not bad, it is real steel, according to Da Chu, at least ten refining more than ten refined iron.

The second furnace is better, Renault is also constantly summarizing, each furnace fine-tunes the carbon content, sometimes good and sometimes bad, several times, Renault already knows which content is better.

In the big tent, Zhu Chongjiu gathered again, and all the generals knew that the decisive battle was just around the corner. General Zhu showed weakness to the enemy, and successively abandoned six battle forts, including the Pioneer Fort, and the general never appeared in front of the army, but Lu Fei occasionally appeared in front of the battle.

Now that the barbarian three-way army has been merged, crossed the vanguard fort, and entered the encirclement, only to collect the net, Zhu Chongjiu is now thinking about how to eat these 200,000 barbarians at the lowest cost.

While they were deliberating, someone outside the door asked for an audience.

"Zhao Duo, let him in. "I heard that it was the head of his own army who invited him to see him, Zhu Chongjiu frowned, but still allowed him to come in.

"See the general, on the order of the gentleman, send the armor to the general to use. Zhao Duo said after the military salute.

"Armor?" What is the use of sending a set of armor at this time?

"Yes. ”

"What's the difference?" If it were someone else, Zhu Chongjiu would have turned his face a long time ago, and he didn't look at when it was, you sent a set of armor?

"Mr. said, the flying ox armor is extremely rare, but it can protect the general from harm, and the quality of the Chu halberd, horizontal knife, and hand relief knife is very average, so please use the general. Zhao Duo said, every time he thought of his husband's expression when he spoke, Zhao Duo felt that he was about to go crazy.

This armor, but he has a share, he has already tried it, not to mention the Flying Bull Divine Armor, Chu Halberd and Horizontal Knife are general? In addition to the Flying Bull Divine Armor, even heavy armor can be easily pierced, and the Divine Weapon is nothing more than that.

"Flying Cow Armor? Okay, present it. ”

Several sergeants behind Zhao Duo walked into the big tent with their armor.

"Zhao Duo, I received the armor, thank you for my kindness. "Even if it is a divine weapon, Zhu Chongjiu doesn't care, this is a war of hundreds of thousands of people, and a set of divine weapons can play a limited role, not to mention that in such a short period of time, he doesn't think that Renault can create a divine weapon.

Several of the most famous divine weapons in Da Chu will take several years to build, what can they do in a month?

Seeing that Zhao Duo did not retreat, General Zhu's eyes were as sharp as a knife: "But there is still something to do?"

"General, Divine Armor, please allow a demonstration. ”

"Okay, you try. "This is to give Mr. Lei face, and if he is a different person, he would have been dragged out to play the board a long time ago.

Zhao Duo turned around and said, "Please borrow the right general's horizontal sword." ”

Yang Feng casually pulled out the horizontal knife, this knife is not ordinary, it was also sent by Mr., he tried it with his own hands, the material is excellent fine iron, more than 100 refining, and it can break several horizontal knives without damage.

Received the horizontal knife, without him talking, the soldiers put on the breastplate of the flying cow armor, with an excited face, they had tried it before, and it was indeed a divine armor.

Zhao Duo slashed out a knife horizontally, and the people in the tent were all generals, so it was natural to see that Zhao Duo had no strength, and this knife was split with all his strength.

There was a crisp sound of the 'bell', and the horizontal knife broke in response.

There was silence in the tent, and after a few breaths, the sound of heavy breathing came. Yang Feng's knife, everyone has seen it, but it was actually broken?

This is the special feature of the Flying Bull Armor, if it is slowly stabbed, the Flying Bull Armor is not even as high as the heavy armor, the more fierce the attack, the stronger the non-Newtonian fluid characteristics of the Flying Bull Armor.

Yang Feng's knife is just ordinary steel, in Renault's opinion, it can only be regarded as a waste product, not even a kitchen knife, naturally it can't be compared with the flying cow armor, the greater the force, the faster it breaks.

Not to mention this horizontal knife, Renault has already tried, even if he uses the manganese steel halberd to stab with all his strength, he can't pierce the flying cow armor, but instead breaks the tip of the halberd.

Zhao Duo threw away the horizontal knife, took a blacksmith's sledgehammer from his subordinates, held the hammer in both hands, swung it vigorously, and smashed it at the breastplate.

'Bell'

Deafening!

This time Zhu Chongjiu looked carefully, as soon as the hammer head touched the breastplate, he felt that the flying ox armor seemed to bulge outward a little, although it was very little, but it couldn't escape the eyes of his grandmaster.

The armor-piercing sergeant retreated more than ten steps in a row, but his figure remained unfolded, with a look of pride and envy on his face.

No shocks? It's incredible.

"Shenjia. ”

"Good armor. ”

Sure enough, it was a divine armor, even Zhu Chongjiu was excited, such a armor, Da Chu couldn't find a second pair.

"Okay, good A, thank you, sir, for your hard work. ”

"Hmm, do you have anything to say?" After the demonstration, Zhu Chongjiu was also very satisfied, why didn't Zhao Duo leave yet?

"General, Mr. said, this kind of armor, the right general also has a set. Zhao Duo said.

"And ......" Zhu Chongjiu was a little dizzy.

"Only these two sets?" Zhu Chongjiu gritted his teeth and asked, a set of divine armor and the ability to mass-produce divine armor are completely different concepts, okay.

"No, there are nine sets built this time, and there are only enough materials. General Luo Yi has one set there, and Mr. and the three members of the Hu family each have one set. Zhao Duo said.

"Can it be mass-produced?" asked Zhu Chongjiu, which was what he was most concerned about.

"There are mines, which are being mined and smelted, and the quantities are scarce. Zhao Duo replied.

"Okay, great, mine with all your might. Zhu Chongjiu was excited, if he could have three thousand flying ox armor, he Zhu Chongjiu would be able to lead the team to fight to the edge of the sky.

"General, Mr. has been busy in the craftsman camp for two days. Zhao Duo said again.

Zhu Chongjiu was silent for a moment, not figuring out what Renault was busy with, isn't the back garden enough? There are not enough arrows, and if you don't have enough long-range weapons, you have to fight with human lives.

Da Chu's armor is much stronger than that of the barbarians, but if you are short-handed, there will inevitably be losses, they are all good children, and it hurts to die.

"Mr. casts sand as molds, cast iron as arrows, and can produce 300,000 arrows per day. Zhao Duo said.

"What?"

"You say it again?"
