On the first day of forging, the craftsmen were forging iron. In order to successfully create a suitable finished product within seven days, one hundred and thirty-two blacksmiths were eventually mobilized to start work simultaneously.

The sound of forging iron was tinkling and it was very lively.

Blacksmithing is a very physically demanding job. Not only does it consume physical strength, but the blacksmithing cannot stop, which makes the whole blacksmithing process tiring and long.

The current working method in the craftsman camp is that each person is allowed to rest for a while after forging for a while. The advantage of this rotation method is that the craftsmen have a chance to breathe and are less tired, and it also improves the overall efficiency. The disadvantage is that,

Due to the addition of rotation, different people exert different force methods and strengths, which increases the probability of defective products when the same iron blank is forged and processed.

Not long after the start of the morning, the craftsmen had only been working for less than half an hour. When Li Mengxi walked around, he found that the craftsmen were generally tired.

Blacksmithing consumes too much energy.

Li Mengxi thought of hydraulic forging. If in the past, hydraulic forging was only known by its name but not its detailed structure, then since the successful use of transmission gears and water mills, hydraulic forging has become something that can be seen and touched.

Hydraulic forging is probably not difficult.

Another thing is that when the craftsmen were forging, they beat the iron for a while and then heated it on the fire for a while. Li Mengxi thought of coke. It is known that the temperature of coke is much higher than that of ordinary charcoal, which makes the temperature of the knife blank heated by coke

Super high, so the blade becomes softer.

The blade base becomes softer, which means that folding and forging is much easier, which means that the forging can be more thorough, impurities can be eliminated more thoroughly, and the forging efficiency is higher.

There is a disadvantageous factor of sulfur in coke. After removing the sulfur, coke has no other disadvantageous factors.

Li Mengxi speculated that adding coke to forging would improve the quality of forged steel and increase the forging speed by several percent.

During the seven-day forging time, the first day was forging, the second day was forging, and the third day was still forging. By the third day, those thinner knife blanks had been hammered into pure wrought iron, and they began to dull.

The fire carburized it.

The ones with the slowest progress are those ultra-long knives that are more than one foot long. The other swords have almost completed the forging process, but these swords are the only ones that are being swung by seven or eight blacksmiths on the forging table that is more than one foot long.

The sledgehammer was clanging from beginning to end.

On the fourth day, several extra-long knives were finally forged.

On the fifth and sixth day, a craftsman took a hard steel sheet with excellent rigidity and scratched the knife base against each other after multiple carburizing treatments. Judging from the scratches on the knife base, the steel strength

Just right.

On the evening of the sixth day, the craftsman used a soft steel bar over one foot long as the core, wrapped it with two layers of hard steel, and hammered it for half a night to shape it into one piece.

In the second half of the night, the knife blank is finely shaped and then placed in a special long fire tank for long-term heating and storage.

One night later, on the morning of the seventh day, the annealing was completed. In the early morning, the craftsmen covered the blades with special mud, leaving the blades uncoated. After covering the soil, they heated several long knives until they were red to white, and the craftsmen took them.

Using the iron clamps, he lifted up the long knife and moved it to the long quenching tank. The hot knife embryo was placed in the grease, and white smoke rose with a sizzling sound.

Several long knives were quenched one after another. When it was finished, the craftsmen checked the quenching results, and the results were not satisfactory.

There are a total of five extra-long knives. After quenching, the knives are either bent or cracked. The best one has an originally straight blade that is bent upwards, which is not at all like the drawing.

The craftsman went to Li Mengxi and asked him to make up his mind. Li Mengxi had seen several knives. Severely deformed or cracked knives would definitely not work. Even if they were repaired, there would be huge hidden dangers.

The craftsmen said that the blade was curved. When Li Mengxi saw this long knife, it was as thin and long as a pole. The blade was not completely straight, but had an excessively natural curvature from top to bottom.

, this sword, which has become straight but not straight due to quenching, is somewhat similar to long knives such as the Miao Dao and Ma Dao in Li Mengxi's impression.

After repeatedly confirming with the craftsmen that the knife had no cracks or anything other than a slight bend, Li Mengxi raised his head and looked at the tip of the knife, which looked black and tall in the sun. "This knife is longer than a gun, right? How long is it?"

?”

Li Mengxi asked curiously.

"It's one foot long." The craftsman replied.

On the last day of the seven-day forging period, a total of thirty-five long knives, including this one-foot-long super-long sword, were put into the charcoal kiln. After the charcoal fire was lit,

After burning for a period of time, with the kiln door sealed and the air cut off, the charcoal kiln will maintain the temperature for a long time, and during the process of stuffing the kiln, the charcoal ash will float all over the kiln. This process of stuffing the kiln is

Tempering and carburizing are performed simultaneously.

——

On the eighth day, it was the agreed date for handing over the knife.

Liu Bei and Lu Zhi came hand in hand.

Dozens of knives, polished, handled and sheathed, were all brought up.

The most eye-catching thing is the craftsman walking in the front. The craftsman is carrying a thin and long object on his shoulders like a bamboo pole. At first glance, he thought it was a stake for testing the knife. When he got to the front, the craftsman

Putting the handle of the knife on the ground, everyone saw clearly that it was actually a knife longer than a gun.

Lu Zhi stroked his beard with his hand, opened his mouth slightly, and looked up at the sheathed sword in astonishment. Suddenly, Lu Zhi couldn't tell whether it was a knife or a strange sheathed spear.

Seeing that Lu Zhi was shocked by this super long knife, Li Mengxi secretly smiled and said, "The blade is one foot long, the handle is one foot and five feet long, and it weighs seventy kilograms.

Seniors might be able to use it?"

After coming back to his senses, Lu Zhi lowered his head and looked at Li Mengxi, meeting Li Mengxi's half-smiling eyes. Lu Zhi was full of pride, "It only weighs seventy pounds, how can you not lift it?"

After he finished speaking, he flicked his sleeves, stretched out his hand, and said, "Here comes the knife."

The craftsman immediately carried the knife to Lu Zhi.

A seventy kilogram knife, this is a seventy kilogram knife with a scabbard. In Li Mengxi's incredible eyes, Lu Zhi took the knife with one hand and lifted the knife with one hand. Lu Zhi held the knife and tested the weight, and said

Good knife.

When we arrived at the knife-testing ground, there were dozens of wooden stakes and wooden sticks such as spears and halberds erected in the field.

The long sword weighed more than sixty kilograms unsheathed. He could hold it with ease, dance with ease, and Lu Zhi carried the knife off the stage. Li Mengxi was curious whether Lu Zhi could really be a warrior.

I saw Lu Zhi enter the scene. He took off his coat, tied off the hem of his clothes, and tied his sleeves with a rope. After getting refreshed, he spat into his hands, grabbed the long knife leaning on one side, and held it with both hands.

The handle of the five-foot-long knife is facing forward, the blade is against the shoulder, and the blade is against the shoulder and backward.

Just then, Lu Zhi stepped forward, stepped forward, lowered his body slightly, leaned forward, and suddenly shouted loudly. Lu Zhi was holding the super long knife that was as long as a bamboo pole, and his whole body was like a spinning top.

Twist it in place.

The knife must be a bit heavy, so Lu Zhi had to use all his strength to swing the long knife.

The silver blade Kacha, which was as slender as a silver whip, whirled onto a wooden stake with a sound, and the wooden stake split into two pieces on the spot.

The knife was too long, and the attack surface was too large. It slashed across one wooden pile, cutting off one wooden stake and affecting two others. As a result, Lu Zhi charged up a powerful blow with all his strength and was stuck before cutting to the bottom.

Already.

Lu Zhi still has some martial arts skills, because it is a sword test, and the target is all the targets standing on the field. Lu Zhi doesn't care about the moves. He only uses one big windmill move with all his strength, carrying the long knife on his shoulder, and his body is

Make a full 180-degree swing and swing the knife with your arm fully extended. The knife cuts out like the wind. It wheezes to the left, cuts off a wooden stake with a kacha sound, then reverses with a wheeze and cuts off another.

root.

From Li Mengxi's point of view, he felt that Lu Zhi was just cutting wheat. He was holding a long plunderer in his hand. He swept it left and right, and the vertical targets and wooden stakes were cut off one by one.

.

In the blink of an eye, half of the target in the field was gone.

When the field was cleared and the knife was fully deployed, Lu Zhi walked to a row of seven vertical gun barrels. He took a deep breath, held the handle of the knife, raised his strength, and pointed the knife at the gun barrel.

Cut it off.

The sounds of kacha came one after another.

With one slash, three of the seven spear shafts were cut off, and the blade was embedded in the fourth spear shaft, cutting it into half.

During this knife test, after the field became a mess and the ground was full of debris, and after everything was cleared away without even a long object, Lu Zhi came back with a knife.

When I checked the blade afterwards, I found that the blade was in perfect condition with not a single chip.

Li Mengxi looked at Lu Zhi who was panting from exhaustion. He smiled and asked Lu Zhi how he liked the knife.

Lu Zhi held the knife and wiped his sweat. He raised his head and glanced at the long knife as high as a bamboo pole from bottom to top. He shook his head helplessly, "Although the knife is very good, it is a bit heavy."

Lu Zhi once had a bayonet sword, but that sword was incomparable to this five-foot-long sword.

When he tried the knife on the field, Lu Zhi had some experience. The knife had regained its weight and was not sluggish at all. It felt smooth in the hand. In addition, the blade was sharp and could be used for hundreds of cuts. In addition, the long knife was astonishingly long.

I have never seen such a long and domineering knife.

Liu Bei laughed and said, "Teacher, please put this sword away. It's a bit heavy and it's a little lighter, so you can put it on display for viewing."

Lu Zhi himself also liked this domineering Zhang Wu long sword. He solemnly asked Li Mengxi, "My little friend, does such a divine product have a name?"

"Uh." Li Mengxi was stunned for a moment. It was just a super steel-clad saber that was a little bigger, a little heavier, and had no name.

After thinking about it, Li Mengxi raised his head and looked at the long sword that Lu Zhi was holding in his hand, which was higher than the human head. He said solemnly, "I heard that there was a huge heavy sword in ancient times. Today's sword is not extremely heavy, but it is extremely long.

, how about calling it [Changque] sword?"

Lu Zhi nodded, Changque Dao, a good name.

I have seen the Changque sword, which is one foot and five feet long. Behind it, there are dozens of smaller long swords. The Changque sword is in front, and the other knives are dim.

Lu Zhi wanted to choose another knife that was lighter and easier to use, but because all the knives were so delicate and beautiful, Lu Zhi couldn't put it down and couldn't make up his mind after choosing them.

Seeing this, Liu Bei smiled and said, "Teacher, if you like it, just take it all."
