At this time, Zhang Beichen has already equipped his new skin [Skillful Craft: Zhang Beichen], and uses the skill "Tempered by a Thousand Tempers".

The bronze hammer weighing thousands of catties was swept by him, and every time the hammer smashed on the iron embryo, there was a deafening loud noise!

The so-called 100 steels are to be hammered repeatedly, folded, and reheated every time they are hammered for a period of time, absorbing the carbon in the charcoal and reducing impurities, so that they can be tempered into real "steel"!

"The prime minister has a lot of strength!"

"Look at his technique, he is so proficient, it is difficult to practice without decades of kung fu! The prime minister still understands the method of craftsman forging? ”

"Is he really a swordsmith?"

Among the hundreds of schools, swordsmiths are also among them. Ou Yezi, the former sword-casting master, forged famous swords such as Zhanlu, Chunjun, Shengxie, Yugu, Juque, Longyuan, Tai'a, and Gongbu.

It is said that the cadre is his fellow brother.

Ordinary craftsmen can only forge ordinary weapons. And the swordsmith can forge spiritual treasures!

Lingbao, that is, a magic weapon that can carry spiritual power and enhance spells and martial arts.

In the process of forging spiritual treasures, it is necessary to constantly use spiritual power to refine weapons, as well as add some other heavenly and earthly treasures, and even flesh and blood tempering.

For example, the two swords of the cadre and the Mo evil are forged by the swordsmith with the combination of flesh and blood!

Zhang Beichen had already begun to use spiritual power with a hammer to start forging weapons.

Bai Zang glanced at him, he already knew that Zhang Beichen did have the skills of a swordsmith, and it seemed to be not bad!

On his side, he had also smelted the bronze material and began to build a bronze weapon.

Zhang Beichen kept beating, and after the iron embryo absorbed enough carbon and eliminated impurities, it had become a piece of steel!

He smelts the billet again and injects it into the mold.

The craftsmen have seen that something is wrong.

"Why is this sword mold so long?"

"At this length, a forged sword can easily break!"

"Yes, if this is true for bronze, iron will break more easily!"

Because of the lack of toughness of bronze, the cast swords are generally short swords, and the length of the arms is the same.

And what Zhang Beichen cast was a long sword, which was nearly seven feet long (about one meter and a half).

And the sword of this era is generally three feet, so the alias of the sword is also called "three feet", such as the Yue Wang sword, the length is 55.7 cm.

Of course, there are also people who forge longer bronze swords, but such swords can be easily broken. It is necessary to cast the sword body relatively thick to ensure that it is not easy to break, and it is not light to wield. In this way, it is better to forge a spear or halberd directly!

In Zhang Beichen's time and space, it was not until the iron-smelting technology matured that the sword length generally reached more than one meter, and the seven-foot long sword gradually replaced the three-foot sword!

After Zhang Beichen condensed the sword embryo, he was still beating repeatedly.

Shirazo and Shiraki no longer pay attention to him, but concentrate on forging swords.

For the livelihood of the craftsmen and their own reputation, they want to forge a sword that will definitely crush Zhang Beichen!

I saw Bai Zang and Bai Mu cut through their palms and cast them with blood, and they didn't stop until they were pale.

After waiting for the sword embryo to take shape, Bai Zang carved the patterns on the fitness, which had the magical effect of guiding spiritual power.

After Zhang Beichen obtained the memory of the Mojia practice in the simulation, he also mastered this skill.

Zhang Beichen also cast it with his own blood, and the Yingyi people were distressed when they saw it, and even wanted to stop.

When the sword embryo was formed, Zhang Beichen also carved the pattern on it.

The sword embryos of Bai Zang and Bai Mu father and son do not need to be hammered repeatedly like a hundred steels, and they are formed faster at this time.

"Zheng Zheng ......" their swords made a clanging sound, as if they were about to take shape.

"It is worthy of being a master of Baizang, it seems that another sword is about to be born!" The craftsmen looked at the past with anticipation and adoration.

I saw that the three-foot bronze sword naturally flew into the sky, suspended in mid-air, and around it, there were three sword shadows formed by sword qi spinning and winding!

Bai Zang and Bai Mu's faces both showed joy, "The sword shadow is out, and the sword weapon is complete!" ”

After the three sword shadows were all integrated into the sword body, the bronze sword glowed with dazzling light, and then it dimmed again.

"Kencheng!" Bai Zang shouted loudly, he withdrew his sword, and the three-foot bronze sword was displayed in front of everyone's eyes. The blade and hilt of the sword are golden, luxurious and dazzling!

Bronze is not blue-gray at the beginning, when it is first forged, it is golden, also known as "Jijin", and after some years, the bronze oxidizes, and then it becomes blue-gray.

For example, in simulated time and space, Xiong Zhitong, the king of Chu, is wearing a golden armor, which is actually a bronze armor!

Everyone stepped forward to observe, and saw that the sword body was thick and the blade was thin, the Dao Dao weapon patterns on the sword body were clearly visible, and the cold light on the sword blade flickered.

"Good sword!" The craftsmen have been amazed.

Bai Zang said even more proudly: "Your Majesty, for the sake of fairness, this sword forged by the minister is called Chopping Iron, which is a three-grade spiritual treasure. But it's so sharp that it's sharpened like clay! Please take a look! ”

Bai Zang deliberately named it Chopping Iron, which means that it can cut off Zhang Beichen's iron sword.

Ying Yiren took the sword, carefully observed, she held the sword flower in her hand, and said: "Whether it is the weight or the feel, it is just right, Master Baizang is worthy of being the famous swordsmith of the Qin State!" ”

When Bai Zang heard this, his face was full of redness. Bai Mu also looked at Zhang Beichen with a proud face, what kind of iron tools, when they encounter their iron swords, they can only be reduced to scrap!

Zhang Beichen had also finished carving the pattern at this time, and his sword was also forged.

"Zheng ......" Zhang Beichen's sword also made a clanging sound, and flew into the air to stop. The three sword shadows are circling, which means that this is a three-grade spirit treasure.

Zhang Beichen only has three realm cultivation, so he can only forge a three-grade spirit treasure at present.

The craftsmen were a little surprised, even if it was only a third-grade spirit treasure, Zhang Beichen's strength in forging surpassed most of them, and he still used iron!

However, the vision didn't stop there, Zhang Beichen's sword body turned silvery-white, which was the color of a hundred steels, and when the sword shadow merged into the sword body, a sword aura soared into the sky, and the roof of the workshop was broken into a big hole!

"What's going on?" The craftsmen looked at this scene in disbelief, "The power of the sword is stronger than the iron sword?" ”

The vision has not disappeared yet, it seems to be attracted by the sword qi, and the phantom shadow of the Xuanniao descends from the sky, circling around the long sword, refining it with spiritual fire! In the sky, thunder descended, tempered for it!

"The old actor is here again!" If he hadn't known that once there was something to improve the fortunes of the Qin State, Xuanniao would appear, Zhang Beichen would suspect that Xuanniao had received his own money!

The emergence of 100 steels, without a doubt, will greatly improve a country's agricultural, industrial and military level, so Xuanniao ran out to perform again.

"Xuanniao quenching, thunder practicing sword!" When Bai Zang saw this scene, he was dumbfounded and muttered, "The old man has forged a sword all his life, and he has never reached such a level!" This is the realm that a swordsmith dreams of, and he has actually reached it! ”

"A sword is successful, and the country's fortune increases!" Shiraki sat down on the ground, "Why is this happening?" This is obviously just an iron tool, just a three-grade spiritual treasure! ”

The surrounding craftsmen even bowed directly, and some people were excited: "The sword quenched by the Xuanyao is enough to become the sword of the princes and kings, this is the sword of the king!" ”

In the swordsmith's pursuit of the sword, there are three realms. The first is the Sword of the Horseman, also known as the Sword of the Warrior!

Those who wielder swords can kill the enemy and make meritorious contributions and become generals!

The second is the sword of the princes, also known as the sword of the king. The sword-wielder can control the fate of a country, rid the demons of the demons, and defend the party.

And the three are the sword of the Son of Heaven, also known as the sword of the emperor. The sword bearer must dominate the world, a sword out, the clouds move in all directions, and the people of the world dare not obey!

For example, the "Sword of the Son of Heaven" inherited by the Qin State is essentially just a sword of princes, a sword of kings!

At this moment, everyone found that the swords they were wearing all emitted the same golden sound, as if they were worshipping the captain's sword!

"The sword of the king, holding this sword, it is like having the blessing of the national fortune of the Qin State, how can the old man match this cutting iron?" Bai Zang felt a deep sense of frustration.

"No!" Bai Mu was not convinced, and shouted: "Even if it is the sword of the king, even if it can carry the power of national fortune, it is only an iron sword in the end." A real sword, not an ornament, not an ornament! It's about drinking blood and killing the enemy! Chop iron, and you can still cut it! ”

Zhang Beichen's iron sword had been tempered, he held the long sword, and said to Bai Mu: "In that case, then let's try each other's swords and see if my iron sword is an ornament!" ”

Everyone looked at the long sword in his hand, the sword was seven feet long, which was already very exaggerated! And its blade is much thinner than a bronze sword.

"With such a thickness, with such a length, and an iron sword, this sword can be easily broken!"

"A king's sword, just use it for decoration. It would be a pity if the sword was broken! The craftsmen sighed, they had decided that the iron sword was inferior to the bronze sword.

"Bai Mu, don't hurt the prime minister!" Bai Zang admonished.

"Don't worry, he can't hurt me!" Zhang Beichen pointed at Bai Mu with his sword, Bai Mu held the chopping iron, and his face was resolute!

He had to prove the centuries-old tradition of their swordsmiths!

"Yikes!" Bai Mu slashed vertically with a sword, he gritted his teeth, his green tendons burst out, and with all his strength, he was bound to cut off Zhang Beichen's long sword!

Zhang Beichen's horizontal sword blocked, the blade collided with the sword body, sparks flew everywhere, and there was a clanging sound.

"This iron sword has not been cut off?" Everyone looked at it in amazement, they thought that if the sword went down, the iron sword would break!

"Replace me!" Zhang Beichen's sword momentum turned, turning defense into attack, Bai Mu hurriedly blocked, this time, he didn't hear any sound of sword blades intersecting.

"Hollowed out?" Bai Mu looked at the chopping iron in his hand suspiciously.

However, in the next second, his expression instantly changed from doubt to horror, and dense beads of sweat appeared from his forehead.

"This ...... That's impossible! This is a piece of iron! How could it be cut off with a sword! He saw that the iron sword in his hand had been cut into two pieces!

The reason why he didn't feel it was because Zhang Beichen slashed too fast, and the iron sword in his hand was very thin, so he didn't react when the sword was cut off, until the cut of iron fell to the ground!

"Cut iron, cut off by the iron sword!" The craftsmen were dumbfounded when they saw this scene!

"This is a sword forged by Master Baizang!"

"Even if it is the sword of the king, without using the power of national fortune and spiritual power, it is just an iron sword! How can an iron sword cut through a bronze sword? ”

"What the hell is going on?" The scene in front of them has subverted their cognition!

Bai Zang squatted down, picked up the broken half of the cut iron, and his hands trembled. This sword not only cut off his sword, but also cut off his arrogance!

"Could it be that the bronze sword is really inferior to the iron sword?" He muttered to himself.

"Of course!" Zhang Beichen said not only to him, but also to all the craftsmen, "Everyone has seen it!" The sword in my hand is longer, more flexible, and sharper than the bronze sword! It's not forged from ordinary iron, it's steel! ”

"Steel?" Everyone was even more confused.

"Yes, steel!" Zhang Beichen said, "The iron you used to forge iron tools can only be called pig iron. There are a lot of impurities, and I use my forging skills to forge steel. It's tougher, the materials are cheaper, and you can forge long weapons! ”

"The so-called one inch long, one inch strong, such a long sword almost occupies an absolute advantage against the bronze short sword! The armor forged with it is also tougher! Farm tools forged with it are cheap and easy to use! ”

"Do you say, is it better to use iron or bronze?"
