Wohu Mountain, Qingzhou.

Therefore, Changqing had an indescribable momentum on his body, his eyes became extremely firm, and he took out the piece of blood wasteland stone and threw it into the furnace.

Ling'er didn't dare to slack off, and twitched the bellows with her right hand, and the black ore in the furnace emitted a scorching fire, and the temperature was extremely high.

To refine a weapon, the material must first be dissolved, poured into a mold, and forged.

The refining tools are divided into three stages, the lowest level is called melting, and for some ordinary utensils, the manufacture is rough, such as some hoes, rakes and other ordinary civilian tools.

The second is to introduce a trace of spiritual energy refining weapons, which is more difficult, and this is what spiritual weapons mean, and the weapons that are exercised are extremely sharp, and the toughness is far higher than that of melting, and the requirements for materials are also extremely high.

The most difficult thing is to let the weapon give birth to a weapon spirit, and in the entire immortal cultivation world, no refiner can reach such a realm.

Even if the dissolution is successful, after pouring into the mold, the hardness increases, and ordinary people cannot temper it, and they cannot create the desired form.

Most of the weapons in the immortal cultivation realm stay in the stage of spiritual introduction, which is a watershed.

Ordinary spiritual weapons, so Changqing can't look down on them, do it yourself, of course, to build the best long sword.

It will take a while for the Blood Wastestone to dissolve, so Changqing walked to the mold, most of them were swords, not what he wanted, and he needed to re-carve a new mold by himself.

He took out his tools, and according to the memory of his previous life, it took him a quarter of an hour to carve out a long sword mold, and at this time, the blood wasted stone in the furnace almost melted, and the red molten iron, splashed with some iron juice, fell on the edge of the furnace.

"Childe, these blood desolate stones have been dissolved."

"Ling'er, take a good look, you have to record all the whole process of my refining, which will help you in the future."

Pour all the iron juice into the mold, put it in cold water, cool it down quickly, and put it on the horn iron pier, so Changqing is naked, soaked in quenching body fluid, and the flesh is infinitely strong, holding a hundred catties of sledgehammer.

"Bang ......"

Therefore, Changqing kept smashing on the sword that had not yet taken shape.

After beating a hundred times, put the knife into the furnace, continue to calcin, knead, pull it out and continue to beat.

Therefore, Changqing's spiritual power was constantly exhausted, and after compression, the purity continued to increase, so Changqing was unwilling to break through the realm and squeeze all the potential of this body.

The spirit sword turned crimson, so Changqing quickly pulled it out, holding the carving knife in his hand, and carved strange lines on the sword body.

At this moment, so Changqing is like being possessed by a god, every movement, flowing water, every time the sword falls, leaving a lifelike mark on the spirit sword, and the long knife that has not yet taken shape exudes a faint spirituality.

Da Da Da ......

A series of dense sounds sounded in Crouching Tiger Mountain, and no one paid attention to it. The last hammer landed on the long sword, making a crisp sword groan, which resounded throughout Crouching Tiger Mountain.

Therefore, Changqing is very satisfied with the long sword, the sword body is three feet long, three fingers wide, and weighs seventy catties.

"In order to practice this sword, all my spiritual power has been exhausted, and I have used some means in the previous war to leave some damage to myself, so I have to take a good rest." Therefore, Changqing sighed.

During the period of recuperation in the old Changqing, Qingzhou was turbulent.
