The snow was covered, and it was much colder in Xiangping City.

However, in the newly built blacksmith shop next to the Taishou Mansion, Le He and several blacksmiths were sweating profusely, and kept beating a long knife repeatedly, which was more than eight feet.

After two months of day and night thinking, Lehe finally created the weapon that Liu Yi wanted.

Looking at the weapons that were constantly forming, Le He's eyes were full of anticipation, this strange weapon was obtained after countless smelting.

"When ......"

After Lehe finished the final hammer, he picked up the weapon, which weighed about 20 catties, with a handle two feet long and a blade six feet long. The blade is wide and sharp, with a sharp tip.

"My lord, the knife is done."

Liu Yi took the newly made long knife, his face was happy, and finally it was done, this is not an ordinary long knife, but a Tang Mo knife.

As a person who crossed over, Liu Yi had already had a soft spot for Modao, and in the early Tang Dynasty, the Turkic cavalry invaded the border several times, and no one was invincible, and it was all the rage.

At the time of this national crisis, the Modao Army was born, and the Turkic wolves who were killed rushed to the chest, crying for their fathers and mothers.

This Mo knife originated from the Western Han Dynasty's horse sword, and absorbed the shape and smelting technology of the Han Lu Mo knife and the long knife of the Six Dynasties, which is not only extremely sharp, but also good at slashing, and is used to deal with enemy cavalry in war, and its role is equivalent to today's anti-tank weapons.

Unfortunately, due to the high cost of the Mo knife and its huge deterrent power, it was used for civil and military officials and the honor guards of feudal towns in the late Tang Dynasty, and in the Song Dynasty, it completely declined.

Liu Yi turned around and gestured to Li Tao, who immediately exclaimed: "Try the knife!" ”

The two soldiers took the bamboo tube that had been prepared long ago, filled it with iron beads, and buried it in the snow.

Liu Yi handed the knife to Guan Hai, and said solemnly: "Old Guan, you can come to this first knife, let everyone see it." ”

Guan Hai excitedly took the Mo knife, raised the knife and slashed, like cutting grass, the bamboo tube was broken and the iron beads were cracked.

"Lord, this is a divine sword!"

Guan Hai looked at the scene in front of him in shock, such a powerful long knife was dozens of times stronger than the knife in his hand.

Liu Yi ordered someone to take gold and jade to try the knife, which was neat and neat, without dragging mud and water, it was really cutting gold and jade, and sharpening iron like mud.

Li Tao looked stunned, clapped his hands and applauded: "Lord, this knife is sharp and impermanent, full of slashing power, and there is a sharp blade at the front end, it is a fierce weapon. ”

"Haha......"

Liu Yi laughed loudly, they are all people who understand, and they have to have 10,000 swordsmen, which is enough to sweep the desert.

"Lehe, how long does it take to build such a weapon?"

Li Tao was moved and asked.

Le He's eyes were full of excitement, and it was a great blessing in his life to be able to create such a good weapon with his own hands.

But this cumbersome smelting, if you want to rush to make a large number of them, it is not an easy task, take the Mo knife in Guan Hai's hand, it took two months to refine successfully, even if it matures in the later stage, a seasoned blacksmith can only refine one within a month.

"It will take at least a month to return to the Chief."

"A month?"

Li Tao was stunned for a moment, thinking about it, such a sharp Mo knife could not be easily refined.

If you want to build a thousand, you need a thousand blacksmiths, but in Xiangping City, there are less than fifty blacksmiths in total, and if you build fifty in a month, it will only be six hundred in a year, which is indeed a long time.

After Li Tao carefully calculated, he couldn't help but feel a little disappointed, if he could make it out as soon as possible, it could come in handy.

"Hey...... It's a pity that I can only figure it slowly. ”

Li Tao sighed.

But at the same time, a strange smile appeared on Liu Yi's face, and the steel frying technique quietly appeared in his mind.

"Ding Dong, congratulations to the host for independently developing the Datang Mo knife and obtaining the steel frying technology."

The sudden divine assistance sent by the imperial sign-in system made Liu Yi excited, the reason why the Mo knife is difficult to refine is nothing more than the piece of steel that is smelted into steel, simply by hand to smelt pig iron, not to mention the time and effort, and the waste of iron.

Liu Yi vaguely remembers that the main difference between pig iron, wrought iron and steel is the carbon content, and iron with a carbon content of more than 2% is called pig iron; Iron with a carbon content of less than % is called wrought iron; Iron with a carbon content of 2% is called steel.

Today's steelmaking process is: charcoal is used as fuel first, iron ore is smelted into a sponge-like solid block in the furnace, and then taken out after the furnace is cooled, which is called block ironmaking.

Lump iron smelting has low carbon content, soft texture, and many impurities, which is called wrought iron. Then use the block of iron as raw material, heat and absorb carbon in the carbon fire to increase the carbon content, and then after forging, remove impurities and infiltrate the carbon, so as to obtain steel.

But this kind of steel is called a block of iron-making carburizing steel.

Although knives made of iron-making and carbon-penetrating steel are relatively sharp, they still cannot reach the level of being able to cut gold and jade, and iron like clay.

Because the quality of this steel is not good enough, the amount of carbon infiltration of this steel, whether the distribution is uniform, and the degree of impurity removal are very difficult to master, and the production efficiency is extremely low.

The strength required by the Mo knife, the performance of this steel is unattainable, so Lehe can only be refined into steel.

The so-called 100 steelmaking is to repeatedly heat, fold and forge the block iron, so that the structure of the steel is dense, the composition is uniform, and the impurities are reduced, so as to improve the quality of the steel, which takes a long time.

But now the steel frying technology given by the imperial sign-in system just makes up for this gap.

Steel frying technology: After the pig iron is heated to melting or basically melted, it is stirred in the furnace and the carbon contained in the pig iron is carbonized by the oxygen in the air, so as to obtain steel. The following points need to be mastered.........

At that moment, Liu Yi wrote down the steel frying technique that appeared in his mind and handed it to Lehe, so that he could ponder it, if he could understand the shortcut, he would rush to make weapons in the future, and the speed would be at least twice as fast.

Le He looked at Liu Yi with a shocked face, and couldn't help asking, "The lord and ancestor opened a blacksmith shop?" ”

"Hehe......"

Liu Yi said with a smile: "I just know a little about the skin, it's not surprising, this matter of rushing to make the Mo knife will be handed over to you, I will let Guan Hai send a hundred soldiers over to assist you in your work, remember, before the Mo knife is in the army, it must not be leaked out." ”

"My subordinates understand!"

Le He took the command.

The next day, a notice was issued in Xiangping City, the government recruited blacksmiths and artists, and gave them a monthly salary of ten taels of gold, which was distributed monthly, which immediately attracted a large number of blacksmiths to apply.

In this way, Liu Yi's first arsenal began to be put into production, Liu Yi believed that sooner or later, one day, his Modao army would appear on the desert, facing the Xianbei cavalry, cutting all the way, thinking about it, beautiful, wonderful.
