In the multi-illusion space, there was still no crisis, everything was so calm, only Fang Heyu's continuous beating sound could be heard, and Fang Heyu once again devoted himself to the cultivation of the forging technique.

The cultivation of the forging technique was indeed too difficult for Fang Heyu, because of his lack of talent, he spent a lot of time and finally stabilized his realm at the Yuan level, and then he tried to impact to the final Enlightenment level.

If he were an ordinary person and practiced a certain method in such a laborious way, it is estimated that he would have given up a long time ago, but Fang Heyu was resolute and tenacious, so he gritted his teeth and persevered, the boring forging technique did not wear out his will, but made him more resolute, and his spiritual power was more condensed, Fang Heyu even felt that his spiritual level was undergoing a transformation, since he reached the realm of heaven and earth by chance last time, his spiritual power finally began to slowly undergo qualitative changes again.

In general, without the support of talent, only by relying on a large amount of time accumulation, master the ratio of various metal ores and the ability to fuse the yuan force, so as to maximize the effect of metal ores.

Fang Heyu has no talent, he can only use time to accumulate, 10,000 years, this time Fang Heyu has been forging for 10,000 years, and finally he has completely mastered the level of entering the Yuan, at least he can be sure that among the various rare metals and ores known, no matter what proportion is used, he can accurately enter the Yuan, so that these materials have the most reasonable Yuan force, and can improve the properties of raw materials, so that the quality of the finished product is higher.

Fortunately, there was time acceleration here, otherwise Fang Heyu would not have so much time to study the forging technique, and if he wanted to use the forging technique to refine the immortal treasure, it would be even more distant.

But now that he can start trying, after so many years of forging, the basic materials in his hands have been squandered, including those that have been snatched from other cultivators over the years, and even the materials that Pei Hong has huge reserves of, there is not much left, and Fang Heyu has to stop cultivating the forging technique.

If you continue to cultivate, you can only use some extremely precious materials, which are extremely painful for Fang Heyu, such as the Rainbow Rock, such as the Earth's Core Rock, etc., which are used for cultivation, which is really too wasteful.

However, at this stage, Fang Heyu naturally would not give up easily, after a full year of rest, Fang Heyu continued to start forging, this time he used precious raw materials, and tried to enlighten the spirit on the basis of entering the Yuan.

Enlightenment is relatively much easier than the first three stages of the Forging Technique. The main thing is to increase the spirituality of the prototype of the immortal treasure with strong spiritual power, and to what extent it can be increased, it depends on the cultivation of the forger itself, as well as the degree of fit between himself and the raw materials, which requires the forger to be very familiar with the first three stages, so that the raw materials can reach the greatest fit with themselves.

In short, the two main points of this process are fit and one's own spiritual cultivation. More than 10,000 years of cultivation had made Fang Heyu's first three stages almost perfect, and his spiritual power was the best even among the Heavenly Immortals, so this stage was much less difficult for him than the first three stages.

Fang Heyu adjusted his state and first created a long sword. The style of the long sword was very ordinary, but the materials used were extremely precious, so Fang Heyu was particularly attentive to this forging.

Thousands of blows, blood coagulation, and entering the three stages of Yuan Fang Heyu asked himself that he had almost achieved perfection, and then finally came to the enlightenment stage. Feeling that the long sword had a bloodline connection with himself, Fang Heyu knew that it was because he was too focused on the blood coagulation process, and doing so consumed his essence and blood greatly, but it would greatly reduce the difficulty of enlightening the spirit.

Spiritual power was injected into the long sword, and the long sword was like a pet touching its owner, and even produced a trace of joy, and then the sword body buzzed, emitting a faint light.

Fang Heyu's eyes lit up, he knew that his first spiritual enlightenment was very successful, and then he quickly dropped the hammer, completely sealing the trace of spirituality produced by the long sword in the sword body.

This long sword is forged here, the entire forging process is over, and the next step is to temper the sword body, and this process Fang Heyu naturally needs to improve.

Fang Heyu released all the Red Refining Immortal Fire and the Blue Immortal Fire, two flames that were already demigod fires, releasing two completely different heats of yin and yang, and under Fang Heyu's control, the long sword was refined.

The process of quenching is to make the prototype of the fairy treasure stronger, and at the same time, to make the fusion between various materials more thorough, so as to completely form the finished fairy treasure.

Fang Heyu found another way, using the two flames of yin and yang to quench, so that all the raw materials were perfectly integrated to a greater extent, and a trace of impurities that could not be eliminated in the forging was eliminated, so as to improve the quality of the prototype of the fairy treasure again.

In the forging process, Fang Heyu also found a drawback, that is, the forging technique can never completely eliminate the impurities of the raw materials, or Fang Heyu's forging technique is not strong enough to completely remove the impurities of the raw materials.

At the end of the quenching, the final enlightenment is naturally a matter of course, the long sword itself has spirituality, and when the long sword completes the entire refining, it suddenly bursts out with a silver light, and the original black sword body suddenly turns into a silver color. The blade of the sword is already extremely sharp without any blades, as if even space can be cut.

Fang Heyu picked up the long sword and waved it casually twice, he suddenly found that although this was also a superb immortal treasure, it was much better than an ordinary superb immortal treasure, and it was conservatively estimated that its attack power was at least several times stronger, which showed how strong the immortal treasure refined by the forging technique was.

Feeling the power of the long sword, Fang Heyu was overjoyed, although this level of weapon, although it was not as good as the source treasure, it was definitely much stronger than the ordinary immortal treasure. In the chaotic battlefield, some immortals with some strength are almost all the best immortal treasures, and when fighting like this, the equipment of the two sides can almost be said to cancel each other, relying on their own strength, and the value of immortal treasures cannot be shown at all. Of course, if one side does not have an immortal treasure, then it will definitely be at a disadvantage in the battle, of course, there are not many such immortals.

Fang Heyu actually refined an alternative immortal treasure between the best immortal treasure and the source treasure, which can be said to have opened up a precedent in this regard. Fang Heyu carefully observed the long sword, and then sighed and muttered: "It's a pity, the forging technique is really too difficult to cultivate, it is really difficult to have no talent, and I don't know if there are any refiners who have cultivated the forging technique for countless years......

Fang Heyu put away the long sword, then recuperated and recuperated, restored his state to the best, and launched the next refining.

In the next few hundred years, Fang Heyu consumed nearly half of the precious materials in his hands, refining a large number of top-grade immortal treasures, including weapons, battle armor, and special purposes, such as fist gloves, combat boots, belts, etc., which were at least enough to equip his team, and there were still a lot of leftovers.

These top-grade immortal treasures are of excellent quality, far stronger than the top-grade immortal treasures refined by ordinary refiners, and they can also enhance their strength from external objects.

In this process, Fang Heyu has a deeper understanding of forging techniques, and at the same time he is more proficient, in general, his forging skills can be mastered, as for why he left half of the precious materials, that is Fang Heyu left for the future refining of the source treasure, with his current cultivation and understanding of the rules, refining the source treasure is still a little inadequate.

The crazy refining lasted for nearly a thousand years and finally came to an end, Fang Heyu put away all the finished products, and then re-entered the cultivation state.

More than 10,000 years have passed, in the outside world, that is, in the past ten years, of course this opportunity Fang Heyu will not waste, even if it is extremely difficult to comprehend the dark attribute here, but Fang Heyu is still trying to comprehend, there is the existence of time acceleration, he naturally does not need to care about the situation of half the effort.

This time he meditated, Fang Heyu sat for thousands of years, for the comprehension of darkness, his entry was extremely slow, mainly because it was filled with a large number of spatial attributes, which not only did not help his cultivation, but also formed a strong interference with him, but with the accumulation of time, he finally made a lot of progress in the dark attributes, but he always felt that he was missing something in the end, otherwise he could have reached a certain bottleneck, so as to break through.

At the age of 20,000 years, Fang Heyu finally stopped cultivating, and he understood that this so-called almost was the real bottleneck, that was the bottleneck of breaking through to the Heavenly Immortals, once he broke through, then it would lead to thunder tribulation. Either he was suppressed in this illusory space, or he was really close to the door, in short, his cultivation here should be over.

Fang Heyu let out a long sigh of relief, and then looked at the void around him, these 20,000 years can be said to be the longest time he has ever spent, but it is an extremely important twenty thousand years for himself, not only has his refining and refining medicine been qualitatively improved, but even his cultivation has finally come to the bottleneck of the Heavenly Immortals, Fang Heyu showed calmness, but his heart was excited, Heavenly Immortals, when he reached this realm, he could go to find Chen Ruoxi and them.

With his comprehension of space, Fang Heyu could clearly feel the intersection of the illusory space and the chaotic battlefield, which was also his way back to the chaotic battlefield.

Fang Heyu waved his hand, directly tore open the space, and then passed through a piece of nothingness, directly came to the node, and then drilled out.

This is the force of space shuttle, with Fang Heyu's current cultivation, he can only shuttle over short distances, if he wants to achieve the long-distance space shuttle like Liu Huiyan, at least with his current cultivation, he can't do it.

Just when Fang Heyu thought that he would return directly to the chaotic battlefield, another endless void appeared in front of his eyes, this space was exactly the same as before, Fang Heyu even thought that he had hallucinated, could it be that the shuttle space failed, and he came back again?

Tearing open the space shuttle again, and then returning to the endless space again, after several times, Fang Heyu finally realized that he should not have hallucinated, but trapped, trapped by this multi-illusionary space.

He finally understood that the crisis of this illusory space did not come from the process of being in the space, but only appeared when he left, and this crisis seemed to be some kind of illusion, allowing himself to go around in different circles in the same place.

Many illusions, Fang Heyu finally understood the origin of the name of the space, it turned out that this place was actually a space illusion, so the space node he felt was also an illusion?

Fang Heyu no longer continued to shuttle, but spread out the twilight snow realm, and then moved quickly in the endless space. For the comprehension of space, Fang Heyu knew that this was by no means an independent space, and there was a connection with the outside world, otherwise he would not be able to enter here.

Since it's not an independent space, then there must be a spatial node that connects with the outside world, and since what I sensed before may be an illusion, then just use a stupid way to search.
