Warrior's Promise

"Swish!"

As he waved his hands, about three hundred kinds of materials steadily flew into the crafting furnace.

He then placed both hands on the two air vents and pushed his Dark Force into the furnace.

The Dark Force instantly turned into furious flames that kept calcining the materials.

Su Mo was highly concentrated and dared not to have the slightest distraction.

He had already gone over the steps countless times, and he knew every detail of crafting a Natal Spiritual Sword.

Therefore, if he made no mistake and completely stick to the crafting method, he could make it.

The Natal Spiritual Sword had no classes or levels like the other weapons. Therefore, it did not take a high-level craftsman to craft it. A King craftsman was already qualified to craft it.

Su Mo's fire property Dark Force was powerful and pure since he practiced an Imperial cultivation skill. The materials were very well calcined under the flames turned by his Dark Force.

In only five minutes, all the materials in the furnace were melted into solution.

The smelting process was demanding. Less smelting would lead to the retention of impurities in the material solution, while over smelting would turn some of the materials into nothingness.

Therefore, Su Mo's control of the Dark Force was critical.

It was worth mentioning that Su Mo's willpower was greatly reduced due to the serious exhaustion of his essence, qi, and spirit.

Although this had an impact on crafting, it was not a big issue since his willpower was much stronger than that of those ordinary people.

Su Mo's willpower rushed into the crafting furnace and carefully checked out the melting progress of the materials.

After a short while when the material solution was refined to a certain extent, Su Mo added dozens of materials to continue refining.

In every few seconds, he put one or several different materials into the furnace.

Although the smelting process was complicated, as long as he stuck to the steps and made no mistakes, it was not that difficult to craft the Natal Spiritual Sword.

The smelting process lasted about an hour. All but a dozen materials, such as the Blood-striped Seed and the Divine Jade, were smelted.

The rest of the materials, such as the Blood-striped Seed, were extremely volatile because of their low melting points. They should only be added during the casting.

A few moments later, Su Mo stopped injecting Dark Force and the material solution began casting.

Su Mo pushed his willpower to the extreme. All of his willpower rushed into the furnace to control the casting of the solution.

This process was relatively short because, under the control of Su Mo's willpower, the liquid was easily shaped into a sword embryo.

Su Mo then instantly put the rest of the materials onto the sword embryo.

"Puff! Puff! Puff!"

The embryo was extremely hot, and the melting points of these materials were extremely low. The moment the materials met the embryo, a burst of white smoke came out and they melted rapidly.

In just four seconds, the Divine Jade and the other materials were all melted and absorbed by the embryo.

After that, Su Mo slightly injected his Dark Force into the furnace as the flame appeared again and calcined the embryo for six seconds, removing all the impurities in it.

Su Mo then waited quietly for the sword embryo to cool down.

As time went by, the sword embryo gradually solidified under the control of Su Mo's willpower.

About two hours later, the sword embryo had completely cooled down and solidified, suffusing out a hazy halo and waves of bleak sword Qi.

At this point, the Natal Spiritual Sword was basically 80% finished. It was not far from being completely crafted.

Subsequently, Su Mo injected his Dark Force again as a raging flame appeared in the furnace.

The sword embryo was calcined nicely. When the embryo reached a certain temperature, Su Mo's willpower dashed into the flames and kept polishing the embryo.

This would be a rather long process because it could not be over-calcined. Su Mo had to pause for a moment every few minutes.

Another one hour had passed when Su Mo stopped crafting.

The Natal Spiritual Sword had been basically crafted, and the progress went surprisingly smooth.

At this point, the Natal Spiritual Sword needed the most important material. That was Su Mo's blood essence.

Only by absorbing his natal blood essence could this Spiritual Sword become his Natal Spiritual Sword and grow with him together.

It would forever be his Natal Spiritual Sword. If he gave it to the others, they could not use it.

The so-called natal blood essence was Su Mo's "heart blood", the blood flowing in his heart.

After a short while, Su Mo opened his mouth and spurted out a drop of heart blood.

"Sizz!"

The light-gold blood dropped onto the Spiritual Sword and was immediately absorbed and disappeared without a trace.

Then, there was a connection built between Su Mo and the sword.

Su Mo then began the final step of quenching.

"Sizz! Sizz! Sizz!"

Quenching liquid was poured over the Natal Spiritual Sword and made beautiful noises.

This quenching liquid was like a spiritual liquid that could cleanse everything. The lead dust on the Natal Spiritual Sword was immediately washed away, and then the sword burst into dazzling light.

After a short while, the light dimmed slightly. Su Mo saw a one-meter-long sword, which was pure white and slightly transparent throughout, quietly suspending in the crafting furnace.

"Swish!"

Su Mo used his Mind as the Natal Spiritual Sword flew out immediately and then revolved around him.

Su Mo finally smiled. This was the real Natal Spiritual Sword, which was far advanced than that half-useless Spiritual Sword he had.

Then, Su Mo used his Mind again as a bright light flashed. The sword suddenly disappeared.

Su Mo closed his eyes and checked his consciousness ocean. He clearly saw that his Natal Spiritual Sword had turned into a one-inch-long sword and was lying there quietly.

The Natal Spiritual Sword needed to be nurtured in his consciousness ocean so as to gradually increase its power. The longer it was nurtured, the stronger its power would be.

"How powerful is it?"

Sumo hesitated for a while and then used his Mind. The Natal Spiritual Sword then dashed out of his consciousness ocean and gently slashed the mountain afar.

"Slash!"

The sword radiance immediately split the peak in two, and the incisions were extremely smooth and neat.

"Good!"

Su Mo nodded upon seeing this. Although splitting a peak was not a big deal, he did not push his Dark Force into the Natal Spiritual Sword. It was a pure physical attack.

The damage it dealt without Dark Force was close to that of his Hornet Sword.

The thing was, that this sword had just been crafted and had not been nurtured much.

Su Mo was very satisfied with the power of this Natal Spiritual Sword. If it was nurtured for a period of time, its power would surge dramatically.

Su Mo was ready to continue crafting the second Natal Spiritual Sword.

However, he suddenly found himself in a very poor state. He was a bit dizzy and exhausted.

His essence, qi, and spirit were already severely depleted, plus the willpower that he had just used to craft the sword and the fact that he had just forced a drop of heart blood out of his heart, he was not in an ideal condition to craft another Spiritual Sword.

Su Mo suddenly felt helpless. The Three Secret Techniques really had consumed him badly!
