After the secondary occupation reached the maximum level, I wore it

The iron essence entered the water without making any splashes. Instead, it sank slowly into the water as if it were falling into a swamp.

Soon, there was a hissing sound in the barrel, and many bubbles began to gurgle from the dark and silent water surface. For a moment, it was like boiling water, and wisps of mist rose up, but the mist was gray and black in color, which should be the impurities in the iron essence.

Shi Yu adjusted her breathing while waiting until there was no movement in the bucket. She then brought another empty wooden bucket and slowly poured the water in it.

When pouring out the water, Shi Yu took a look and noticed that the Killing Spring Water was different from the original one: "The water color has become lighter, and the Killing Spring Water has been consumed."

This is also expected.

The iron essence sank to the bottom of the bucket, and after the water was poured out, its full appearance was revealed.

When Shi Yu saw the iron essence the size of a baby's fist at the bottom of the bucket, he was a little surprised: "It's only half the size of the original one."

Today, the size of this piece of iron essence has shrunk to half of its original size. The slight rust impurities on the surface have completely disappeared, and it is now radiating a cold light and showing its sharp edge.

"The impurities have been removed. The Shaquan fruit really has the effect of purifying and refining."

It seems that my previous guess was not wrong.

After observing it more carefully, Shi Yu reached out and lightly touched the surface of the iron essence. The sharpness was so sharp that it could almost pierce his fingers. This fascinating sharpness was not like what ordinary iron essence should have, but more like a higher-level black iron essence.

She thought thoughtfully: "It seems that it is not just purification, the quality of the iron essence itself has also changed."

Iron essence is the most commonly used metallic and stone spiritual material when refining magical instruments. Its own value is not high and it can only be used to refine the lowest grade and first grade magical instruments.

But the iron essence in front of me, which has been tempered by the killing spring water, is probably enough to refine a second-grade magic weapon just in terms of quality.

After looking at it for a while, Shi Yu became more and more satisfied: "With the Killing Spring Water, the spiritual materials soaked in it are of excellent quality and have no impurities. They can be used directly for refining."

"Skipping the smelting step actually saves a lot of trouble and time."

Shi Yu was pleasantly surprised, and put in the piece of Luoxia redwood that he had just melted. When he took it out, it was also smaller than before.

She then took out the remaining materials, iron essence, black light stone, silver shark scales, etc., and put them in one by one to soak and temper.

The color of the Shaquan water became visibly lighter.

While waiting, she was not idle. The spiritual materials that had been purified and tempered by the killing spring water still needed to be roasted over charcoal fire to soften them, and then hammered into shape with her spiritual consciousness and spiritual energy.

When refining a weapon, a refiner usually draws a diagram first, disassembles the weapon pattern in advance, conceives the arrangement of the array and the combination of restrictions, and then follows the diagram one by one when refining, so as to avoid being in a hurry, making mistakes and wasting spiritual materials.

But right now it's just refining a first-grade magic weapon. Apart from taking some effort, it's really not difficult.

By this time, Yu had already mastered the art and had all the steps in his mind, so there was no need to draw any diagrams.

She was seen holding the refined iron essence in her hand, looking at it for a moment, then rekindling the sweet pine charcoal fire, wrapping the iron essence with spiritual power, moving it over the charcoal fire, and beating it into a flat, curved strip.

……

Several days passed by unknowingly. Shi Yu was immersed in his own world, unaware of the passage of time.

Except for the time when he had run out of magic power and had to take the Dew Condensing Pill and sit cross-legged to recover, Shi Yu spent the rest of the time hammering these spiritual materials for refining weapons.

If you feel tired and sleepy, sleep for a few hours to recover.

Her spiritual energy cycled between being depleted and restored, and her cultivation improved during this training.

In the Dantian, the number of cyclones rotating around the yellow bud has increased to nine, and the tenth cyclone is showing signs of taking shape.

Seven days later, all the materials were hammered into shape.

The killing spring water in the bucket has completely turned from its original dark color to clear and transparent, and it has been completely consumed. Fortunately, there is still a lot of killing spring water left in the Yin-Yang Life-Knocking Bell.

According to the idea in his mind, Shi Yu first engraved the source pattern on the talisman pen and set up restrictions.

She knew a lot of restrictions, but there were only a few restrictions that could be engraved on low-grade magic weapons.

"Just engrave the two restrictions of 'Spiritual Transmission' and 'Increase Endurance'."

The former can enhance the spiritual energy transmission ability of the talisman pen, making it more sensitive and stable when making talismans; the latter increases the durability of the talisman pen, preventing it from being damaged or consumed too quickly during use.

A first-grade magic weapon can have at most two or three restrictions engraved on it. Having more restrictions would be disadvantageous, and there must be no conflict between the restrictions, otherwise the pen body will not be able to withstand it and will easily collapse. These two types of restrictions are sufficient for a short period of time.

The pen blank made of sunset redwood and green marten's belly hair was still a little dull, but with the engraving of the prohibition, it gradually began to glow.

Looking at this scene, Shi Yu felt an indescribable sense of satisfaction.

The Three Thousand Great Daos are diverse and colorful. Although weapons, elixirs, formations and talismans are secondary professions, once one reaches a certain level of attainment, they are also beneficial to the improvement of cultivation.

For example, when refining an elixir to the best quality, one can comprehend the origin of heaven and earth from the patterns on the elixir; another example is when refining a magic weapon, a strand of "treasure energy" will be produced at the moment it is refined. By absorbing it into the body and taking the opportunity to practice, one can also improve one's cultivation.

This was the case at this moment. The moment the restriction was engraved and the talisman pen took shape, a flash of light appeared on the pen body, and the whole pen gave people a completely different feeling from when it was just a embryo.

The precious light is bright and full of spiritual energy.

The talisman pen in front of him was extraordinary among the first-grade talisman pens. It was much better than the first-grade talisman pens he had seen in Tongyi Pavilion before.

Being able to refine a talisman pen of such quality using ordinary redwood and the belly hair of a green-bristled marten, in addition to Shi Yu's own advanced refining skills, was also inseparable from the help of the Killing Spring Water.

After being refined and purified by the killing spring water, the quality of these spiritual materials has been greatly improved.

The moment the talisman pen took shape, an almost imperceptible faint precious energy emerged from it and penetrated into the body, flowing along the Shiyu meridians and into the Dantian.

Shi Yu had been paying attention and noticed that after the treasure energy was absorbed, his cultivation level increased slightly.

At this moment, the vague tenth cyclone in Dantian became more and more solid, and entering the second level of Qi Refining was just around the corner.

After refining the talisman pen, Shi Yu took a short rest and immediately started refining the alchemy furnace.

The volume of the alchemy furnace is larger than that of the talisman pen, and the types and quantities of spiritual materials used are also more than those of the talisman pen. Naturally, it is more troublesome to refine than the talisman pen.

Shi Yu spent two days refining the alchemy furnace before he completed it, and then added three restrictions on it: "gathering spirits", "transmitting spirits", and "explosion-proof".

At this moment, the finished furnace is about one and a half feet high, made of iron essence, and dark red after being integrated with Xuanguang Stone. The restrictions engraved on the surface exude a mysterious atmosphere, and the furnace cover is round-headed, dotted with silver shark scales, which refract light under the sun, colorful.

All the materials used to refine the alchemy furnace have been quenched and purified by the killing spring water. With all these factors added up, the grade of the alchemy furnace in front of us is only one step away from the second level.

The little bit short of that was simply because Shi Yu’s cultivation level was not high enough and he couldn’t achieve it.

The moment the elixir was successfully refined in the furnace, a wisp of precious energy also penetrated into Shi Yu's body, which was several points more than the precious energy generated by refining the talisman pen.

This wisp of precious energy entered his body, prompting his cultivation to improve. In his Dantian, the tenth cyclone was completely condensed, no different from the other nine. At this time, Shi Yu also successfully entered the second level of Qi training.
