Chu won the world with fish and rice, it is said that compared with other countries in this era, in some important counties and counties have appeared twice a year rice, although the taste is not very good, for the old Qin soldiers who are used to eating corn, it is also very good to change the taste occasionally.

The young officer of Gongzi was holding a big bowl of rice in his hand, with a big piece of oily fat and a few autumn stalks on the rice, taking two mouthfuls of rice, taking a bite of the fatty meat, eating with oil in his mouth, and muttering unclear in his mouth: "I said Brother Bai, this time you must promise me, give me 30,000 people, I promise to take Changping in half a month, or seven days?" Please, I've been reading arithmetic every day in the academy these days, and my head is going to explode, and I finally have a fight, and this first prize must be given to me! ”

"You can take the lead, but Che Yingzi'an and they also think about it, your eldest brother came to my military tent camp last night and said that he wanted to take Changping in person. I really don't know what you're thinking, Changping is an important town in the south of Wei, an important port connecting Weishui and Yingshui, there are 8,000 heavy soldiers in the city alone, and 20,000 soldiers, 2,000 sailors, and the city is strong, easy to defend and difficult to attack, you can take 30,000 people? Do you want me to pull all the 150,000 troops under Changping City, just like Pang Juan besieged Handan, and set up a position to fight for a few months? ”

"That's what it was fun to do."

"You're in for a treat, the army will be killed alive! So this time when we attack Wei, the first thing we have to do is not to capture the city, but to kill the enemy! ”

"I don't understand again, how can you kill the enemy without attacking the city? If Changping is not taken, we will not be able to move forward, and the Wei army will cut off our back road. The army will be besieged! ”

"Cut off our back road. Wei Jun? I'm just afraid they won't come."

Bai Dong smiled slightly. took the rice bowl from the flea's hand, hurriedly pulled out two bites, jumped up and said, "Let's go, follow me to Ou Yeliang to have a look."

One month after the army trained in Shangsi, Bai Dong received a reply from the king of Chu, and the king of Chu was really happy to hear that the Qin army was going to attack Wei through Chu; This was the case during the Warring States period, the princes of all countries were all in one mind, wishing that other countries would fight as fiercely as possible. What's more, the situation of Chu is very special, bordering Qin, Han, Wei, Song, Lu, and Yue. Naturally, there must be a lot of friction. Now that the Qin State, which is gradually becoming stronger, wants to challenge the overlord of the Wei State, the King of Chu happily wants to feast his ministers.

If you look at the excitement, you are not afraid of it, you must add fire, and the relationship between Chu and Qin has always been good, so the king of Chu has made a lot of effort to take the Qin army into the country this time, not only vigorously blocking the news, but also preparing a large number of Chu armor flags for the Qin army, as soon as the Qin army enters the Chu Pass, it immediately changes its clothes, not to mention that the spies of Wei are not as good as this, and even the army stationed in Chu may not be able to distinguish it. It's the same for the sake of being so painstaking. Let the Qin army be able to secretly and safely cross the Chu realm, and then beat the old Wei people fiercely!

I still have more confidence in Handan Baidong. The Warring States also produced strong cities, how could a capital like Handan Linzi be broken if it was broken? Even Pang Juan is the same. So he was not in a hurry, after the army arrived at the bank of Yingshui, while camping and settling down for the soldiers to recuperate, every day big fish and meat to replenish the body, while calling Ou Yeliang, got a drawing for him, after explaining the things in the picture, Ou Yeliang's eyes widened, as if he wanted to see through Bai Dong: "Bai Zi can know that this thing is not conducive to secrecy, once it is used on the battlefield, it will make the Wei people know?" Do you know how many changes this thing will cause once it comes out? ”

"Once this thing comes out, it will greatly reduce transportation costs, the economy will be stimulated, and business will be more developed. As for the Wei people will know, it doesn't matter, this battle has too much impact on the Qin State, if this battle is won, the stronger the Qin State will be, and the Wei State will be defeated in ten years, so I am not afraid of them knowing this secret. ”

Bai Dong smiled slightly: "But it's not easy to learn from me, this thing seems simple, if it is cast in bronze, it will lose its toughness, if it is cast with iron, it is not hard enough, even if Wei Man comes out, the energy and money spent on frequent replacement alone can make them feel terrible." So this thing also needs a special metal to cast. ”

"You're finally willing to tell the secret, tell me quickly, what kind of special metal is it?"

Therefore, Bai Dong is not afraid that Ou Yeliang will betray Lao Qin, this guy can get the bones of dead people to refine swords, it can be seen that he is a technical maniac, treating this kind of technical maniac, money, beauty, and national honor are all fart, only brand-new technology can make him fascinated and then chase away.

Ou Yeliang is now the big boss of the old Qin military rank department, and since he rushed into the military ordnance department, this product has been asking Lao Qin for a hundred years and thousands of years of iron mother every day, which has caused Yingquliang to have a headache. In fact, the so-called iron mother is just a block of iron with high purity and easy decarburization, which is not as brittle as ordinary block iron and cast iron, and is used to make agricultural tools, and will be hunted down by the army when made into weapons. But in this era when there is no even invention of the method of frying steel, once the 'iron mother' with higher purity falls into the hands of people like Ou Yeliang, then it can be turned into a metal close to 'steel' through various means, casting a divine weapon, where will there be many such good things, and ask for it like rice and wheat all day long, who can stand it?

In the end, it was Bai Dong who came forward and coaxed Ou Yeliang to the army, promising him a new refining method to get unprecedented metal, so he was willing to follow, and he pestered Bai Dong for a long time when he was in Shang Si Mountain, and now he finally got what he wanted.

When the young officer Gongzi followed Bai Dong to Ou Yeliang's territory, he saw from afar that Gongzi Qian and others were also there, and it seemed that they had been waiting for a long time; When everyone saw Bai Dong coming, they all laughed and said, "Why did the general come?" The ink line and Ouyeel palm furnace are there, saying that they are waiting for you to open the furnace."

Walking into Ou Yeliang's sword house, Bai Dong immediately felt the heat in his face, Bai Dong took off his robe and threw it to the Bai family veterans who came with him, and said with a smile: "I know that there will be friction between the two of them, let's go, let's go and see." Didn't the eldest prince ask me yesterday what I should rely on to win the Wei people? The answer lies in this sword house. ”

Now Ou Yeliang's sword house is actually a big refinery, and it doesn't matter if he can refine a divine weapon comparable to Mo Ye, the big palm furnace is now concerned about new metals.

During the Spring and Autumn Period and the Warring States Period. Although there are occasional 'iron mothers' with higher purity. But even the most primitive mild steel has never appeared. Even a master craftsman like Ou Yeliang often worries about the material, once he gets the iron mother with a low carbon content, he will not hesitate to use human bones and animal bones to complete the primitive carburizing process, no matter how you look at it, he looks like a madman who refines his sword and refines it to the point of going mad.

Bai Dong's so-called new metal is actually derived from the original iron ore, but in order to get iron with lower carbon content or even low-carbon steel and medium-carbon steel, it is necessary to come up with the 'frying steel method' that was not invented until the Western Han Dynasty. No matter how good the piece of iron is, it is not as good as a piece of low-carbon steel, let alone steelmaking with guò carbon as a reducing agent, and the carbon in the reduced steel is carbon dioxide or carbon monoxide. The Qin army attacked Wei Tu with only 150,000 people, and the mobility must first be ensured, once there is a horseshoe, a large-scale movement war becomes possible, and to deal with the Wei warriors wearing triple armor, strong bows and crossbows and sharper arrows are also essential, and it is not a mistake to say that the 'steel frying method' is the key to winning the Wei people.

"Open the furnace!"

I saw Bai Dong arrive. Ou Yeliang roared, and the main furnace immediately burst into flames. Countless iron ores are put into the central refining pot, which gradually softens and melts. The Western Han Dynasty in China can invent the method of frying steel, but Europe is lagging behind for more than a thousand years, the reason is in the temperature of the furnace, because of the development of ceramic technology in Huaxia, there is no difficulty at all to achieve the need for 1,200 degrees of frying steel, any porcelain kiln can do it; Europeans are different, until the Middle Ages castles were still large stone piles, commoners still lived in houses made of wood, because they didn't know how to burn bricks at all, and when they saw porcelain from the East, the nobles and lords were treasures, and they took a porcelain urinal to show off all day long. It is precisely because of this kind of heritage in Huaxia that Bai Dong's move out of the steel frying method in the Western Han Dynasty is not a shocking thing.

The molten iron, which contained a large number of impurities, gradually boiled, and the ink line standing in front of the furnace tested the fire, and shouted: "Fry!" ”

A few stone sticks were immediately stretched out from the beam hanging above the refining pot, and the guò rope pulled the control zhì and began to stir clockwise in the molten iron, and at the same time, some craftsmen also began to pull the bellows and blow the molten iron with air guns, and soon saw that a mass of stain-like things appeared on the surface of the boiling molten iron, and it was some impurities in the ore that were fried out.

Even Ou Yeliang is very appreciative of the ability to see the fire of the ink line, patting him on the shoulder, Ou Yeliang ordered people to pour the fried molten iron into the mold, one arrow iron cluster quickly formed, while the iron cluster has not cooled and hardened, Ou Yeliang personally picked up one with fire tongs, grabbed a pinch of bone powder from the bag and sprinkled it evenly on the iron cluster, and then backfire and burned red, repeatedly forged with a refining hammer, and finally put it into cold water and quenched it and took it out. It is the anomaly of a god soldier like Mo Ye.

Bai Dong said with a smile: "Come on, put on three layers of heavy armor for the wooden people who try arrows, all of them must be the best bamboo and copper armor, and this general wants to try arrows!" ”

The wooden man wearing three layers of heavy armor was quickly placed fifty steps away from everyone, and the arrow cluster created by Ou Yeliang himself was also placed on the tip of the arrow, and after being loaded into the strong crossbow made by the public loser, he let an ordinary soldier hold the crossbow and fire, only to hear a few soft sounds of 'Bo Bo Bo', this arrow broke through the three layers of heavy armor and shot the wooden man through!

Gongzi Qian and Che Yingzi'an and other old men in the army walked over and looked at each other, one by one excited, and laughed: "It turns out that this is the key to winning the Wei State?" The general is really a god and a man! Although this arrow was not refined by Bai Dong himself, looking at Ou Yeliang's expression, everyone knew that this must be Bai Dong's means.

Bai Dong smiled and shook his head: "Although this thing is good, it is not the key to winning the Wei people, start refining the 'horseshoe', this thing only needs to fry the iron juice, there is no need to be as troublesome as refining arrow clusters." (To be continued......)
