After Zheng Yuan prepared the water for quenching, Wei Minsheng also tasted it, and it turned out that the contents of the small bag should be the most common salt.

Came to the place called the intermediate frequency smelting furnace again, and with the help of Wei Minsheng, Zheng Yuan used the "invisible fire" to heat the machete and prepare for quenching.

As the blade of the knife slowly turned red, Zheng Yuan's eyes narrowed and narrowed, carefully observing the subtle changes in the color of the blade.

When he felt that the heat was about the same, he took out the machete and quickly put it into the quenched water that had been prepared earlier.

Where the machete came into contact with the water, a slight explosion sounded a burst of white mist, and the blade quickly cooled down.

After the quenching was completed, Zheng Yuan tapped the blade with his fingers, listened to the sound, nodded with satisfaction, and said to Wei Minsheng with a smile: "My knife has been completed." ”

For the metallurgical technology of this era, Wei Minsheng did not have much hope, his requirement was that he only needed to cut ordinary iron wire, and he did not expect to be able to reach the level of special steel in the real world.

Therefore, he took out an ordinary iron wire the thickness of wheat straw that he had prepared a long time ago and handed it to Zheng Yuan.

Zheng Yuan bent it with his fingers, it was indeed an ordinary wire, and he was relieved.

If this wire was made of the same material as the steel rope on the ship, the machete he had just made would not have the confidence to cut it.

This knife uses that kind of invisible and colorless "divine fire", and the material itself is equivalent to the quality of 100 steel, and it feels much better than what he has made with any kind of furnace fire before.

This can be heard from the sound of finger tapping just now, but how good it can be, Zheng Yuan's heart still doesn't have much bottom, because he has never created something of this level before.

Putting the wire on the wooden bench, the hand holding the machete was already sweating slightly, and whether it succeeded or not was under this knife.

If you cut it off, you can get the status of an official member of this Huaxia Kingdom, and your family will be able to have no worries about food and clothing for the rest of your life.

If you keep chopping, you don't know when you will have such an opportunity, only to see if your child has the ability to pass the Huaxia State assessment.

Relying on descendants to solve his own food and clothing problems, Zheng Yuan always felt a little embarrassed.

Gritting his teeth, Zheng Yuan waved his right hand holding the machete vigorously, and then slashed it fiercely.

With a "tuk", due to the excessive force, the blade of the machete all fell into the wooden bench.

The wire in his hand is still there, but the wire on the other side of the machete no longer knows where it has flown to.

Turning the wire in his hand, the incision was very smooth, and it should have been cut with a machete.

But it is not known whether the blade of the machete was damaged, and if it was the result of losing both, then this quenching still did not achieve the desired effect.

With a strong right hand, the machete was taken out of the wooden bench, and when he saw the light, fortunately, the blade was not cracked.

Zheng Yuan smiled and happily handed the machete in his hand to Wei Minsheng.

Wei Minsheng took the machete and checked it carefully, and it was indeed the conditions in the mission description that had been met.

Looking at Zheng Yuan's proud appearance, Wei Minsheng decided to press him, lest he not know the height of the sky and be arrogant.

So, Wei Minsheng said casually: "Count you barely passing." ”

"Barely passing?"

Zheng Yuan already felt in his heart that the machete he had just created was the most perfect in his life, but he only got a comment that barely passed.

So, he said unconvincedly: "Then may I ask sir, what kind of level do you have to achieve to not barely pass." ”

The two words were deliberately accentuated by Zheng Yuan, expressing his dissatisfaction to Wei Minsheng.

Wei Minsheng walked to the side of the tool cabinet and pretended to take out a machete for cutting bones produced using modern technology.

He turned around and handed it to Zheng Yuan and said, "You can use your knife to slash at this knife, and you will understand what I just meant by barely passing the level." ”

Zheng Yuan took the machete, and his eyes were immediately attracted by the smooth and mirror-like Xueliang blade.

This...... How is this done?

No matter how good the knife is, it is impossible to make the entire blade as bright as the blade when polishing.

Moreover, the sharp edges and corners of this knife are as if they had been cut with a sharp blade.

The sound of the fingers tapping was crisp and long, and it did feel much better than the machete he had just made.

However, Zheng Yuan, a technical talent, is not easily impressed by superficial phenomena, and they only agree that seeing is believing.

Although the confidence in my heart has been shaken a little, I still have to fight for face, so I played a little cautiously.

Zheng Yuan held the knife given to him by Wei Minsheng with his left hand, put the blade up on the wooden bench, and then raised the machete he had made with his right hand and quickly slashed down.

Although the action of force is relative according to physics, two knives slash at each other, and both knives will be subjected to the same impact force.

But like Zheng Yuan, there are still some subtle differences.

The moment the machete is swung quickly, it slides a short distance in the direction of the blade the moment it comes into contact with the stationary machete.

In this way, the impact force of the blade is dispersed to this small section of the blade, which is actually equivalent to a large contact area many times over, and the pressure on the blade is reduced.

The force part of the stationary knife is almost a point, and when it is subjected to the same impact at such a point, the pressure is many times greater.

Therefore, in real life, you will find that two identical wooden sticks strike each other, and the slower swing speed is easier to break.

It's not luck, it's a skill in the use of power.

Zheng Yuan had the idea of fighting in his heart, and wanted to use this technique to make up for the possible gap between the two knives.
