And what Lu Buqi wants to build is not exactly a two-handed sword, what he wants to build is a sword that can be used with one hand and both hands, so the sword body is destined not to be too wide, after all, in that case, it will affect the use of the sword.

Yes, the volume of the same weight of dark iron should be the same, if it is not widened, then Zuihou will not become a cylinder?

The one who will ask this question is undoubtedly a layman, and the stacking can change the density of molecules. Theoretically, it has a strong enough ability to even compress a cubic meter of dark iron into a palm-sized size, of course, this kind of terrifying liliang is probably only available to the immortal gods.

Lu Buqi didn't give up, but Lu Buqi believed that he had enough strength to complete a hundred stacks of Xuantie, which was second only to steel jade in density, and that should be able to achieve what he needed in his heart.

"Look, have you noticed that Sikong Weidian's return to the furnace this time is obviously faster than that of the master who does not abandon him, does this mean that he is more powerful?" A bystander gradually discovered a problem.

"What is your theory? Different playing styles have different speeds of dissipation. The person who knows a little about forging skills answers: "How can you judge the skill from the time of returning to the furnace?"

Another crowd who seemed to know a lot about forging stroked his chin three inches: "In my opinion, this master and Sikong Weidian are probably rivals in chess, even if the weapon is created, I'm afraid it will be difficult to distinguish between the superior and the inferior!"

But as time passed, two hours had passed, and ordinary people couldn't see why, but Sikong Nian was a little surprised in his heart: "It's been sixty-one times since I returned to the furnace, and Uncle Wei Dian's physical strength is showing signs of declining, but this kid doesn't have the slightest fatigue?"

When half an hour had passed, the dark iron in Sikong Weidian's hand began to be cast, but Lu Bu was still forging the dark iron.

In the blink of an eye, another half an hour passed, and the Xuantie Sword in Sikong Weidian's hand was completely formed. But Lu Bu didn't give up, and he was still forging at this time.

Complicating a complicated look, Sikong Weidian threw the heavy sword in his hand into the quenching pool, and then took out the tempering with extremely skillful means, seventy-nine refinements, which can barely be called eighty refinements of the Xuantie broadsword, such a level can definitely be regarded as a high level in the entire Yunze Kingdom.

But looking at Lu Bu again, it was not until Sikong Weidian successfully completed the blank of the Xuantie broadsword with a hilt one foot long, a sword body four feet long, and a width of about nine inches, that he began to cast.

And from Sikong Nian's mouth shape, Sikong Weidian can see that one hundred and three times of overlapping, he obviously loses in this regard. However, there is no zuihou result, Sikong Weidian still does not believe that the gap between them will be so big, in his opinion, Lu Buqi is likely to overdraw his physical strength for the sake of victory, if Lu Buqi is not successful in casting because of lack of physical strength, then Lu Buqi This is a failed forging.

Some people may say, what physical exhaustion, this time it was not completed, rest will play next time. In fact, this view is wrong......

On this shijie, the reason why mainstream weapons are rated as good by the number of stacks is because most metals can be stacked to enhance their density and strength.

However, this kind of strengthening is added by external force in a short period of time, and if it cannot be successfully forged and quenched in a continuous period of time, it will be in vain. Because the timing of the quenching has a great effect on the strength of the weapon, and once there is too much pause, then the effect of many stacks will quickly disappear.

What's more, this kind of stacking has a high recognition of the forging frequency, if it is a few different craftsmen taking turns to build, the biggest possibility is to create weapons and equipment full of cracks, unless these craftsmen are like-minded people, otherwise multi-person cooperation, it can't be used on stacking jishu.

Therefore, mastering the stacking technique is the basic of a blacksmith, and a mature blacksmith must know how to retain sufficient physical strength. Because in addition to the most time-consuming stacking, there are also small hammer casting molds with very high jishu content and extremely energy-consuming in the rest, and then there are steps such as quenching and tempering. If you insist on the number of stacks and overdraw your physical strength, then the casting will not be successful, and it will be difficult to make a semi-finished product.

Just like Sikong Weidian, he has a good grasp of it, and when the tempering is completed, his physical strength is not much left. And the Darkiron Broadsword is basically completed, after all, things like polishing, sanding, and opening can be done later.

But when Sikong Weidian came to see Lu Buqi as an outsider, he suddenly found that he did have a big gap with Lu Buqi in this regard.

Especially when he saw Lu Buqi replace the sledgehammer with a small hammer and smash the first hammer at the crimson long black iron, the tongue of fire that had been soaring into the sky in the oven actually poured towards him, like a wave of wheat blown by the wind.

"Hiss......" Sikong Weidian gasped.

When Lu Buqi smashed the second hammer again, the tongue of fire poured over again, and when the heat wave vaporized Lu Buqi's figure a little blurred, Sikong Weidian suddenly looked up to the sky and sighed: "Peerless sword-casting genius, no one can beat it!"
