Casting itself is a difficult skill to learn, and craftsmen in each place have their own fixed processes, and if the master is willing to teach, it is relatively quick to learn.

But it's hard to master it.

In fact, the warriors more or less knew the art of casting, but there were not many people who could really be called proficient, and Zhao Hong happened to be proficient in the casting method of blacksmiths.

This is not to say how powerful Zhao Hong himself is, but because Zhao Hong himself is a powerful warrior in the realm of rejuvenation.

With his great strength and meticulous control over his own strength, as long as he practiced the art of casting, he could withstand ten years of hard training for ordinary people.

In fact, the biggest factor affecting casting is that there are only two points of casting.

The first point is the environment, that is, what kind of space can be provided for casting, what kind of tools can be provided.

The second thing that affects casting is the material used in casting, and you will definitely not be able to forge an indestructible blade with a pile of mortal iron.

Even if someone really has someone who can use the mist made of mortal iron as an invincible divine weapon, it is not that the blacksmith who casts it is powerful, but the person who wields the weapon is powerful.

There is indeed that kind of warrior with extremely powerful life force, after being wound with life force, the weapon in his hand can compete with the divine weapon even if it is cast with mortal iron.

But the environment and tools don't really determine the standard of a blacksmith's casting skills.

To distinguish the skills of a blacksmith, it is still necessary to look at the skills of the blacksmith himself.

And Zhao Hong obtained this skill by virtue of his physical fitness beyond ordinary people and his ability to control strength, so it is not surprising that Zhao Hong is now a skilled blacksmith.

Regarding the matter of repairing the weapon, Zhao Hong had already practiced countless times in his mind, and now he followed the process of the drill in his heart, and there were no mistakes in the process, but in the end, when the weapon was about to take shape, it failed.

When the weapon was about to take shape, an astonishing heat suddenly burst out from it, and in an instant, a wave of heat surged out of the weapon, engulfing the surrounding environment along with Zhao Hong.

"Whew!"

"Not good!"

Zhao Hong was startled, and hurriedly used his life force to protect his body, when this heat passed, Zhao Hong saw the scene around him that had been ravaged by high temperatures, which can be said to be a mess, fortunately, the furnace is mostly designed to set fire, very resistant to high temperatures, and there are not many flammables, otherwise it is already a sea of fire here.

But even then, the combustible things around him were burning.

Zhao Hong ignored these, looked at his Qingtian Golden Heavy Knife, and then breathed a long sigh of relief.

"It should be the power of the Gathering Sun Spirit Text, fortunately, this temperature is very short, it is only a momentary explosion, and it is not enough to really hurt the Qingtian Golden Heavy Knife, and it will not affect my repair. ”

Zhao Hong breathed a long sigh of relief and continued to repair the weapon, this time he was more careful.
