After a while, everyone came to the Blacksmith's House.

What surprised Xu Li was that when Zhao Kuo appeared, all the blacksmiths and apprentices immediately fell to their knees.

"See the Lord!"

This voice not only contains respect, but also has a fanaticism.

It was as if the fans of later generations were as fanatical as their idols! Even Zhao Kuo was a little shocked.

Guo Ye carefully picked up a long sword and respectfully handed it to Zhao Kuo: "Please look, Lord, this is the first finished product!"

Zhao Kuo looked at the long sword carefully.

The back of the knife is thick and wide, the tip of the knife is extremely sharp, and the entire blade is very smooth, giving people the feeling of light flowing on the knife.

Zhao Kuo gently flicked the blade, and a long and beautiful sound came into his eardrums. The speed of light flowing on the blade seemed to have accelerated, making people feel dizzy.

"A good knife, indeed a good knife."

Zhao Kuo breathed a sigh of relief.

In fact, as early as the Han Dynasty, the Chinese people had invented the casting method of making steel in hundreds.

As the name suggests, the finished product obtained after repeated tempering. In terms of sharpness, the steelmaking method of making steelmaking is actually better than Zhao Kuo's iron filling method.

But Steel Fencing is not flawless, it has two major shortcomings.

The first one is expensive. The steel consumed by forging a steelmaking weapon is very amazing. At present, a steelmaking knife is equivalent to two hundred adults who eat a year of food.

The second disadvantage is that the forging process of Baijian Steel is very complicated, which causes a lot of time to be consumed.

In history, Cao Cao of the Three Kingdoms era once asked the skilled craftsmen to forge five steel knives, but it took three years to forge these five steel knives! These two shortcomings mean that the 100-fen steel knives can only be used to cast a small number of magical weapons and cannot be used to make large-scale standard equipment.

The method of steel filling used by Zhao Kuo is different. This method can reasonably select materials according to different uses, give full play to the advantages of various materials, save valuable materials, and reduce costs and costs.

Generally speaking, the edge of the steel knife mainly plays an assassination function and requires a relatively high hardness, so that the knife can be sharp. Therefore, steel with a high carbon content and a high hardness should be used to make it.

The back of the knife mainly plays a supporting role and requires relatively good toughness so that the knife will not break when it is subjected to a relatively large impact. In this way, you should choose a cooked iron with low carbon content and high toughness.

It was precisely because of the above similar understanding that Qi Wuhuaiwen could cleverly combine the knives with iron and steel when making knives, that is, "Su Tie". In this way, using the knives and steel just right in the right place, not only satisfies the different requirements of different parts of the steel knife, but also saves a lot of expensive steel, which is conducive to the promotion and popularization of steel knives.

This is what Zhao Kuo needs, and it can widely popularize the magical weapons in the hands of every soldier under Zhao Kuo! Zhao Kuo smiled and said, "Get a few sets of armor to try it."

A moment later, a set of bronze armor and an iron armor hung on a cross-straw man stand.

Bronze armor is the standard armor of the Qin army today, while iron armor comes from the Korean army.

Zhao Kuo took a deep breath, waved the long sword in his hand, and slashed the Qin army's bronze armor.

A sound of gold and iron intersecting, and the Qin army's bronze armor was cut in half cleanly, without even the slightest obstacle.

Xu Li, who was behind Zhao Kuo, shook his body and widened his eyes incredibly.

Xu Li fought with the Qin army in the battles of the wars of the Changping and the battle of Changping. Although the armor of the Qin army was mainly bronze, due to the superb bronze smelting technology of the Qin people, the protection power was almost no different from iron armor.

If it was on the battlefield, Xu Li would not use his sword to stab the Qin people's bronze armor directly, but instead started looking for fatal parts like the throat or less protection like the arms.

Now, the steel knife suddenly split the Qin people's armor, giving people the feeling that it was not a carefully crafted set of bronze armor, but a piece of ordinary firewood.

"This, how is this possible?"

Xu Li murmured to himself, subconsciously rubbing his eyes.

Zhao Kuo shouted again, and the sword light rose again, slashing towards the Korean army's iron armor.

This time, a louder sound of gold and iron intersecting, and the Korean army's standard armor was also cut in half.

Xu Li: "..." If the bronze armor of the Qin army just now cannot explain the problem, then the iron armor of the Koreans is completely indisputable.

When it comes to smelting iron tools, South Korea is the best in the world! Nowadays, the number one Korean armor in the world is no different from the paper-pasteed steel knife forged by Zhao Kuo.

Xu Li took a deep breath and a stream of passion surged into his heart.

Too strong, it's too strong! Think about it, if the Zhao army and the Korean army face each other in the future, the Korean soldiers will come over with a sword and will not pierce the Zhao army's armor at all. Then the Zhao army's soldiers will use a backhand to split the Korean soldiers and their armor in half... It's simply crushing.

With such weapons, Zhao's army is like a tiger with wings! Xu Li raised his hand and slapped himself hard.

"Bang!"

It hurts so much.

But Xu Li did not complain, but was extremely happy in his heart.

It's really not a dream. The Lord really developed this unprecedented powerful forging technique, allowing Guo Ye to forge such a magical weapon.

Xu Li gasped and looked at Zhao Kuo with respect.

Regarding military strategy, Zhao Kuo is the best in the world.

Unexpectedly, Zhao Kuo was also invincible in the world in terms of weapon smelting.

What kind of virtue is Xu Li? I can follow such a lord! In front of Xu Li, Guo Ye was very excited to pick up the iron armor of Chu army: "Master, please look at this cutout. It's so smooth, it's simply, no, this is the real iron-cutting like mud!"

Zhao Kuo looked at the long sword in his hand and found two small, extremely subtle gaps on it, but not obvious.

Zhao Kuo nodded with satisfaction. After all, it was used to deal with the strongest bronze and iron weapons in the world. It would not be realistic if it was unscathed.

Judging from the subtlety of this gap, at least a few hundred sets of armor must be split before it will be scrapped.

If a soldier can kill hundreds of enemies at the cost of scrapping a sacrificial iron knife in a battle, then Zhao Kuo just wants to say - just chop, don't cherish my sword! If an ordinary sword is used to split armor, it will take time and effort, and at most two or three sets of armor will be scrapped directly.

This is the huge gap between craftsmanship.

This is the power of time travelers! Knowledge changes everything.

When it comes to knowledge, Zhao Kuo can say confidently: "The whole world is together, I'm in a hurry!"

Guo Ye said respectfully: "As such a magical weapon, I would like to give you a name to you."

Zhao Kuo smiled and said, "This kind of knife will be called Su Tie Knife in the future! The forged sword is called Su Tie Knife, and so on."

Guo Ye quickly agreed with an extremely respectful expression.

For this great blacksmith who devoted his life to smelting, Zhao Kuo at this moment was like a priest. He was not only Guo Ye’s lord, but also Guo Ye’s smelting and the leader! Zhao Kuo reminded him again: “Remember, the weapons of the Tie must be kept confidential and must not be circulated outside the world!”

Originally, Zhao Kuo wanted to get this kind of subsidence method to bring the entire smelting level of Zhao's country to a new level. However, King Zhao's successive actions made Zhao Kuo somewhat disheartened, so he decided to keep it for the time being.

Since you are in the first year of junior high school, don’t blame me for being the fifteenth day of the lunar calendar!
