After the material melted, Lin Feng controlled it through his divine sense, he could remove all the black impurities, or take out the yellow and brown in it separately, and he could also mix the yellow and brown materials with the two attributes according to any proportion required, and if Lin Feng was willing, he could also mix some impurities into it!

In fact, it only took a short time to melt this piece of material, and the spiritual power in Lin Feng's body was exhausted within these few breaths! When Lin Feng urged the magic trick to take out that piece of material, it had been completely divided into three parts, and it was lying quietly in the Sumeru Illusion Ring. []

The black impurities are completely useless, and this can be judged with the divine sense, because there is no trace of aura inside the black impurities. But the other two pieces are different, not only are they rich in aura, but also the body after cooling is crystal clear, and the appearance is as smooth as jade.

After refining a piece of material, Lin Feng seemed to be unsatisfied, and after running the Quenching Dragon Technique for several hours in a row, the spiritual power in his body returned to its peak state again, so he took out another piece of material, and then began to refine it.

This time, the results were completely unexpected. The material did not melt as quickly as expected, and the flames in the red stamens continued to bake it, but it remained unmoved. [~] Until the spiritual power inside Lin Feng's Yuan Shen was consumed, this piece of material was still not melted at all!

Lin Feng was puzzled at first, but later slowly discovered that the temperature of the flame did not seem to reach the melting point of the material. In other words, the highest temperature that this red flower in the immortal net can reach should be related to Lin Feng's strength. The stronger Lin Feng's strength, the purer the spiritual power in his body would be, and the higher the temperature of the red flower would be.

In order to verify this speculation, Lin Feng also urged the first nameless magic technique of the Immortal Net, and the two primordial gods in the inner area of the immortal net, that is, the two primordial spirits of the foundation building period captured from the lewd leopard and the lewd wolf, injected a large amount of origin spiritual power into Lin Feng's primordial spirit at the same time!

After the first devouring, Lin Feng knew that there was a huge risk of indiscriminate devouring before the physique and meridians had not reached a considerable level. However, this time he didn't devour it himself, but sent the swallowed origin spiritual power directly into the red flower to see what the temperature of the flame was this time.

The result really exhilarated him! The foundation building stage monk's origin spiritual power was much more refined, and the flames suddenly skyrocketed from more than an inch long to two inches, and the temperature was even higher several times! In just a few moments, that piece of material had been completely melted!

After understanding this wonderful use of the immortal net, Lin Feng quickly stopped refining the materials, because the primordial spirit of the foundation building period cultivator was quite precious to him, and it was impossible for him to waste it on the refining materials at will. (・)

The impurities of the second piece of material were also taken out of the Sumeru Illusion Ring, and all that was left was a dark red fire attribute material the size of an eyeball, which was nearly ten times smaller than the original, but the purity was terrifying.

Sending the Taiyi Divine Chapter back to the Sumeru Illusion Ring, Lin Feng took out another jade slip, which was obtained from the unknown secret room in the Elixir Valley, which recorded a very mysterious sword technique: the Nine Yuan Sword Technique!

Ever since he got this sword technique, Lin Feng hadn't studied it properly, and when he immersed his divine sense in it, he fell into a state of comprehension for a long time again, and if there were no outsiders to disturb him, he seemed to be staying inside endlessly.

However, he still wants to come out, not because someone bothered him, but because after comprehending to a certain extent, he can no longer continue to comprehend. The mystery of the Nine Yuan Sword Technique, he didn't even seem to be able to comprehend the Qi cultivation stage, but could only hover at the observation level of the Xuanzhao period.

The reason why it is said to be the degree of observation is that the monk of the Xuanzhao period has not yet been able to formally cultivate the Nine Yuan Sword Technique! He can only do some preparatory work for the first glimpse of the path, that is, to shape the auxiliary exercises of the Nine Yuan Sword Technique, so that the spiritual power in his body can complete the corresponding operation according to the requirements of the Nine Yuan Sword Technique.

The reason why the Nine Yuan Sword Technique is called an auxiliary exercise is that it cannot replace the status of the main exercise. The main cultivation method is specially used to improve the level of cultivation, such as Lin Feng's Quenching Dragon Technique, as long as you persist in cultivating without understanding, you can keep moving forward according to the Xuanzhao period, the Qi training period, the Dan period, and so on.

The auxiliary exercise method is different, it needs to rely on the results of the cultivation of the main exercise, with the help of the spiritual power that has been refined, to urge its internal effect. For example, the Nine Yuan Sword Technique, it can't increase Lin Feng's cultivation realm like the Quenching Dragon Technique, but Lin Feng can use the Nine Yuan Sword Technique as a means of attack from the beginning of the Qi training period, the higher his realm, the greater the power of the Nine Yuan Sword Technique!

The stage of the rotation period is completely to build the foundation, Lin Feng strictly follows the requirements of the Nine Yuan Sword Technique, so that the spiritual power operates to all parts of the body according to the prescribed pattern, and creates a primitive form for this set of auxiliary exercises, and when he uses the Nine Yuan Sword Technique in the future, the spiritual power in his body will automatically play a miraculous effect according to this line.

The years of cultivation are long, sometimes they are short, and some people are often able to enter the realm of forgetting things and self, and at this time, their progress is also the fastest. And at this time, Lin Feng entered this state.

Lin Feng's progress at this time was not the cultivation realm, but the foundation of the Nine Yuan Sword Technique! As the saying goes, everything is difficult at the beginning, especially a profound method, its initial is often the most difficult to get started.

If spiritual power wants to be molded in the body, it is like water leaving an imprint on a stone, it requires not only time, but also more difficult accuracy! As long as there is a slight deviation, the model of the imprint will be inconsistent with the requirements of the Nine Yuan Sword Technique, and the power will be greatly reduced when used in the future.

As time passed day by day, the spiritual power in Lin Feng's body continued to circulate continuously, and some places flowed more frequently, so the imprints left were more profound, and some places only flowed a few times occasionally, so the imprints were also very shallow.

Later, the appearance of the brand had gradually taken shape, and it was difficult for the spiritual power in Lin Feng's body to leave scratches on the brand, at this time, he should have stopped, and after his strength had gone further, he would have continued his unfinished shaping.

However, Lin Feng knew that this kind of realm of selflessness was very difficult to encounter, so he simply didn't do anything, continued to urge the devouring technique in the immortal net, and used the origin spiritual power provided by the primordial spirit of the lewd leopard to impact the nine-element sword technique auxiliary technique that was about to take shape.

The spiritual power of the cultivator in the foundation building period was naturally extremely pure, it was like a sharp knife carved on wood, and it quickly shocked the operation system of the Nine Yuan Sword Technique into an established prototype, and the accuracy was not bad at all!
