At this time, Lin Feng was sitting in a high-level earth fire room, adjusting the state of his whole body, preparing for the next refining weapon, the high-grade earth fire room that Lin Feng rented now was much better than the earth fire room he rented before, because now this high-grade earth fire room was specially used to refine spiritual weapons, and the high temperature that the earth fire in it could reach was twice as high as before, and the earth fire was more stable.

Since most of the qi refining materials of spiritual weapons are very rare, and their attributes in all aspects are much higher than those of refining magic weapons, it is natural to completely melt these rare materials at a higher temperature, and the most different between refining spiritual weapons and refining magic weapons is that spiritual weapons need to be "quenched" and "quenched" in the process of refining.

The "quenching" used is a small jar of "cold spirit water" next to Lin Feng now, this small tank of "cold spirit water" was purchased by Lin Feng from the store for twenty spirit stones, and together with renting this high-grade earth fire room for three days, a total of twenty-six spirit stones were spent, and nearly five thousand spirit stones were spent on which qi refining materials were purchased, which still does not include "rutile" Inside, even with Lin Feng's current net worth, he couldn't help but shout that the refining weapon is really not something that ordinary people can support, it consumes too many spirit stones, no wonder those refining masters are all from the sect, and with the strength of one person, it is difficult to support the consumption of the refining weapon.

"Quenching the spirit" for the general refiner is to use the blood of the spirit beast as the material for the "quenching" of the aura, and the refined spirit weapon needs this heart blood to open the spirit, and only the spirit weapon that has passed the spirit is the most spiritual, and the blood of this high-level spirit beast is also easy to buy outside, and it is not very expensive for Lin Feng, but Lin Feng did not buy it, because Lin Feng had other plans in his heart.

At this time, after Lin Feng took a deep breath, he had already improved his state to the best, and he was constantly cheering himself up in his heart, and he would definitely be able to successfully refine this "Golden Red Sword" , Because Lin Feng vaguely felt that the trip to the cave ruins after five days was probably not so simple, so Lin Feng was eager to refine this high-grade spiritual weapon within five days, because once this spiritual weapon was successfully refined, then there would be a great improvement in Lin Feng's strength, after all, if you want to make great progress in cultivation to improve your strength, this is not something that can be done overnight, but it is possible from the magic weapon, after all, the magic weapon is also a part of your own strength.

For Lin Feng, refining the spirit weapon was the first time, and he was naturally nervous in his heart, just like in the process of refining the first refining material "ink stone", although he had already refined the "ink stone" in the jade slip I have seen the method dozens of times, but Lin Feng still almost failed, but fortunately, due to his rich experience in refining low-level magic weapons in the past, Lin Feng controlled his spirit silk at the most critical moment, and finally succeeded, which is why Lin Feng has been repeating refining low-level magic weapons, because refining tools can be bypassed like cultivation.

With the success of the first ore purification, Lin Feng's nervous mood has slowly calmed down, followed by the purification of the second ore, and then the third, two hours later, Lin Feng finally completed the purification of all the refining materials, at this time Lin Feng couldn't help but sweat profusely, and it was also a very spiritual power consuming thing for refining materials.

The next step was fusion, for this step, Lin Feng did not rush to take it, but took out two spirit stones, and slowly recovered the spiritual power he consumed.

Half an hour passed, Lin Feng completely recovered the spiritual power he had consumed, and then Lin Feng put the refined materials into the high-temperature earth fire one by one according to the order in the booklet, so that they slowly melted, and after all the materials were melted, Lin Feng used the specific method recorded in the booklet to fuse all the materials together.

The next thing is to shape the fused materials, for this step Lin Feng has long been proficient in his heart, after all, there are dozens or hundreds of low-grade magic weapons in the early stage, but even Lin Feng, who has skilled experience, took more than an hour to succeed in this step, with the last law decision, the sword tire in the earth fire has already been formed, Lin Feng instantly introduced it into the "cold spirit water" next to it, and then heard "呲呲" The sound came out instantly, and then the whole body of the sword fetus cast by Lin Feng seemed to absorb water, and after a while, the full tank of "cold spirit water" was reduced by half, and it was not until only a third was left that the sword fetus stopped moving.

Lin Feng grabbed it casually, and a flying sword with a dark red body appeared in Lin Feng's hand, the style was extremely simple, Lin Feng stroked the blood groove on the sword body and the extremely sharp blade, and laughed happily, although the golden red sword in his hand had not yet carried out the final step of "quenching" , so it has not yet shown the spirituality that the aura should have, but the most difficult step in refining this spiritual weapon has indeed been completely completed by Lin Feng, it can be said that this flying sword has been completely refined, because the probability of failure in the quenching stage is extremely low, few people fail in the quenching step, and most of the failure of the spirit weapon refining is in the previous step.

Lin Feng deliberately tried the quality of the current flying sword, so he took out a lower-grade magic weapon, and then Lin Feng had luck and spiritual power on both sides, and then slashed together violently, and sure enough, the lower-grade magic weapon was instantly cut into two pieces by the sword tire of the golden red sword.

Lin Feng happily got up with the sword fetus and left the burning position of the ground fire, and came to the other side of this high-level earth fire room, that is, the place where the "simmering" was burning, this high-grade earth fire not only has a large space and a high temperature of the ground fire, but also has two kinds of flames: ground fire and simmering fire.

What Lin Feng has to do now is to put the sword tire that has been refined on top of the simmer, and then quench it, I saw Lin Feng sit down in front of the simmer, and then the sword tire was placed horizontally on top of the simmer, and then continued to play a series of spiritual power against the sword tire, this simmer is not as fierce as the ground fire, so the temperature on the sword tire does not rise very quickly, and after a quarter of an hour, the sword tire slowly becomes red.

Lin Feng knew that the best time to quench the spirit had come, only to see Lin Feng controlling the spiritual power with both hands, and instantly erected the horizontal sword fetus, and then bit the tip of the tongue violently, and the two mouthfuls of blood on the tip of the tongue instantly sprayed on the front and back of the sword fetus, as Lin Feng's essence blood sprayed on the sword body, it was instantly absorbed by the sword fetus, and then Lin Feng saw that the golden red word on the blood groove of the sword body instantly glowed red, and then the golden red sword's whole body suddenly burst out with a powerful spiritual power, blowing Lin Feng's robe up.

Then a crisp sword chant itself came out from the golden red sword, and then I saw the golden red sword happily spinning in the air a few times, and then flew straight to Lin Feng's cross-legged body, looking at the dark red aura that kept flashing on the sword, Lin Feng excitedly stretched out his left hand and held it on the hilt of the golden red sword, and instantly a feeling of flesh and blood came from the sword.

Sure enough, as Lin Feng expected, the spiritual weapon that was tempered with the blood on the tip of his tongue could naturally have a subtle connection with the spiritual weapon, and it was naturally more convenient to use.
