Under the accumulation of countless small crystals, evil thought crystals, super-grade demonization crystals, and law crystals, Zi Yan's level quickly broke through from the original middle-level secondary artifact to the level of high-level secondary artifact, and moreover, Zi Yan's breakthrough to the high-level secondary artifact level only consumed more than 10% of all materials.

As for the remaining ninety percent of the materials, Lin Wu estimated that it was enough to push the Ziyan level to another level, reaching the level of a top-level secondary artifact.

And in fact, just as Lin Wu expected, after all the materials were integrated into the Ziyan blade, Ziyan's level increased again, reaching the level of a top-level secondary artifact.

However, at the moment when Zi Yan's level was raised to a top-level secondary artifact, Zi Yan's demon spirit instantly became violent, and the monstrous evil power rampaged through the huge quiet room with impunity.

Even, Ziyan began to attack Lin Wu. Of course, Ziyan's chaotic attack couldn't hit Lin Wu at all, but the problems shown in this were very serious.

Zi Yan's level has indeed improved, and it has crossed two levels in a row, but Zi Yan's two levels have only crossed in the four aspects of its sword body material, energy, evil power, and law power.

As for the most important demon spirit, because the two top-level secondary artifacts that Lin Wu had decomposed had not obtained spiritual sense, at this moment, Ziyan's demon spirit power had not increased to the level of the original middle-level secondary artifact.

Using a mid-level sub-artifact-level demon spirit to control the top-level sub-artifact-level body, this is like using an ant's soul to drive an elephant's body, of course, if it's just like this, it's not a big problem, ants can't drive the elephant's body, but they can not move.

However, among the four powers that Zi Yan has promoted, there is an evil power that determines whether the magic weapon is strong or not, and when Zi Yan was promoted to a high-level secondary artifact, with the special and powerful of the Zi Yan Demon Spirit, he was able to control this powerful evil force. However, when this evil force reached the level of a top-level secondary artifact, the gap between the two orders made the Purple Flame Demon Spirit unable to control this powerful evil force, causing the Purple Flame Demon Spirit to fall into a rage by the evil force. And the furious Purple Flame Demon Spirit began to attack everything in its attack range frantically.

Looking at Zi Yan in the rage, Lin Wu's expression was not so flustered, because, when Zi Yan level was promoted to a high-level secondary artifact. Ancient had already reminded Lin Wu that this would be the case.

And Lin Wu chose to continue when he knew that it would be extremely risky to continue to improve the Ziyan body and evil power, so he was naturally prepared. （_）

I saw Lin Wu take it out of the space bracelet, and the evil origin that was decomposed from the peak sub-artifact level magic weapon threw it into the furious Ziyan.

That evil origin is close to the purple flame in the rage. Immediately, he was devoured by Zi Yan, and after devouring the evil origin, Zi Yan, who was still raging, instantly calmed down, and even the evil power that leaked out quickly converged, at this moment, Zi Yan gave people the feeling that it was just an ordinary long knife.

Seeing this scene, Lin Wu couldn't help but have a smile on his face. Because he succeeded. The Purple Flame Demon Spirit, who had obtained the origin of evil, had now gained the ability to control the power of evil. This can be seen from the fact that the Purple Flame Demon Spirit has completely reined in the evil power that has leaked out.

From this moment on, the Purple Flame Demon Spirit will not be affected by the evil force, which will also lay a solid foundation for the Purple Flame Demon Spirit to give birth to spiritual intelligence, and when the Purple Flame Demon Spirit gives birth to spiritual intelligence, it also indicates that Ziyan will set foot in the realm of artifacts.

This is also why the Evil Origin is an indispensable factor for the promotion of top-level sub-artifact-level magic weapons to artifacts. Because only with the magic weapon of the origin of evil can you completely get rid of the influence of evil forces. In order to make the demon spirit give birth to spiritual intelligence, and the demon spirit to give birth to spiritual intelligence is an important sign of the promotion of magic weapons to artifacts. …,

With joy. Lin Wu walked to the center of the magic array and pulled out the purple flame that had become simple and unpretentious, and then, Lin Wu injected his power into the purple flame.

Suddenly, the monstrous purple flame with the rolling evil power burst out from the Ziyan knife, and the powerful power was definitely not comparable to the previous mid-level sub-artifact level Ziyan, and I don't know if it was because of the increase in strength, the color of this Ziyan's flame also became a little darker, from the original faint purple flame to the pure purple now. Of course, compared to the purple demonic flame on the magic sword, this is still a hundred and eight thousand miles behind.

Compared with a powerful artifact like Apophis, Ziyan is naturally incomparable, but compared with the current Ziyan and other top-level sub-artifacts, that Ziyan is definitely stronger than other top-level sub-artifacts by virtue of the combination of the three that are not inferior to the top-level sub-artifact, the powerful purple flame and the evil origin, and this is still in the case that the level of the Ziyan Demon Spirit has not been improved, if, in the future, the power of the Ziyan Demon Spirit will also reach the level of the top-level sub-artifact, then Ziyan will definitely become the strongest weapon below the artifact.

Familiar with the power of Zi Yan after promotion, Lin Wu put away Zi Yan, and then, Lin Wu took a little time to strengthen the Bone Hell Qiankun Sword with that special divine power material, of course, this time Lin Wu strengthened more cautiously, and raised the sword body level of the Bone Hell Qiankun Sword to a middle-level secondary artifact and stopped.

After completing the ascension of the Bone Hell Qiankun Sword, Lin Wu immediately walked out of the quiet room.

"Ancient, how many days have it been?" Walking out of the quiet room, Lin Wu asked Gu Gu, who had been paying attention to Ziyan's promotion, and Lin Wu had already forgotten the time.

"Well, it's been 3 months." Soon, an ancient voice rang out.

"3 months, it's been so long, I don't know what the situation is in the human world." Hearing the ancient words, Lin Wu couldn't help but be shocked.

"Ancient, when will I return to the human realm?" Immediately, Lin Wu asked.

Hearing Lin Wu's inquiry, Gu Gu pondered and said: "Lin boy, if you want to return to the human world, you must meet two conditions, one is to collect the materials for arranging the teleportation array, and the materials required for the teleportation array from the heavenly realm to the human realm will feel pain even if you are a god, of course, you have obtained the treasure of the God of Shadows, many of which are the materials needed to arrange the teleportation array, as for the missing ones, you can go to Miri to borrow some, so the first condition is no longer a problem." ”

"So, what about the second condition?" Lin Wu asked hurriedly.

"The second condition is strength, using the teleportation array to enter the human realm from the heavenly realm, the risk is very large, if you are not careful, you will fall directly into the spatial turbulence, and the laws of the human world will repel anything that enters from the heavenly realm, so Lin boy, you must have a strong strength to resist the risk of teleportation and the repulsion of the laws of the human world." After speaking, Gu paused slightly and continued.

"Of course, you are originally from the human realm, and when you return, the power of the laws of the human realm will be less repulsive to you, but as you stay in the heavenly realm for more time, this advantage will gradually disappear. Therefore, Lin boy, you must use the fastest speed to reach the strength to return to the human world. Finally, the old man said with a serious face.

"Then what kind of strength can successfully return to the human world?" As soon as the ancient voice fell, Lin Wu couldn't wait to ask.

"Demigod high level, the lowest demigod high level, this is still the case that your breath has not been assimilated by the heavenly realm, otherwise, the stronger your strength, the more difficult it will be to return to the human realm." Gu thought about it slightly and said.

"Demigod High Rank?" The ancient words made Lin Wu feel a lot of pressure, the current Lin Wu was still at the first level of demigods, even if he unlocked the seal of the ghost hand, he was only a mid-level demigod, and he did not meet the ancient requirements at all, and it was too difficult to break through at each level of the demigod level. ..., however, as if he felt that Lin Wu's pressure was not great enough, at this time, Gu Gu threw out another sentence, "Oh, by the way, Lin Xiaozi is only half a year away from your breath being assimilated by the Heavenly Realm, which means that you must use half a year to advance to the demigod high level." ”

Half a year, demigod high level, these two words that can never be put together, are now really placed in front of Lin Wu, for demigod-level powerhouses, half a year is just a blink of an eye, but Lin Wu must complete the leap from the demigod middle level to the demigod high level in this 'blink of an eye' time.

"Now, it seems that it is the only way to use it." Faced with the urgent situation in front of him, Lin Wu also had to fight the idea of the Shadow God Godhead.

Of course, because of the inconsistent attributes, Lin Wu could not directly refine the godhead of this god of shadows, but Lin Wu could exchange it for godheads of other attributes, such as wind system, soul system, and blood line, as for the dark system, except for the fragments of the god of ghosts and gods, the others were of little use to Lin Wu, and the chance of exchanging the godhead of the god of shadows for the fragments of the god of ghosts and gods was almost zero.

This also made it impossible for Lin Wu to obtain new ghost god godhead fragments to quickly improve the strength of the ghost hand, only to break through from the other 3 series of powers, and the strength of the other 3 series was only at the first level of demigods, that is to say, Lin Wu had to cross two levels from the primary level of demigods to the high level of demigods in half a year.

Of course, this is not impossible if the corresponding godhead can be obtained.

"Hey, it would be nice if I could refine the fragment of the ghost godhead in the ghost's hand." When he made up his mind to get rid of this shadow god godhead, Lin Wu couldn't help but sigh in his heart.

After all, the relationship between the Godhead is too important, and it will be a lot of trouble to get rid of it, and if you don't get it right, it will cause great danger. If it weren't for the fact that the ghost godhead fragment was hidden in the dark void godhead in Lin Wu's ghost's hand and couldn't come out, so that Lin Wu couldn't refine that ghost godhead fragment at all, Lin Wu wouldn't have let go of the shadow godhead, even if he wanted to get rid of it, he would have to wait for Lin Wu to have enough strength.

Although, I have decided to get rid of the shadow godhead in my hand, but who to turn to? Needless to say, the demigod-level powerhouse has the strength to obtain the godhead, even if the demigod-level powerhouse has the great luck to get a godhead, how can he keep it, he has already refined it himself, even if the attributes do not match, it is a big deal to abolish the whole body cultivation and rebuild, and it is not a problem to recultivate even if there is a godhead.

The demigod powerhouse was eliminated, then, Lin Wu's choice of target was only the gods, but the risk of trading with the gods was too great, and a godhead was enough to make a god snatch it regardless of face, at that time, Lin Wu's situation was very dangerous, and Lin Wu couldn't expect all the gods to be like the god of shadows and didn't even have an artifact.
