The artifacts on the ground disappeared one by one, and all of them melted into the evil spirit, and as time progressed, the brilliance emitted by the evil spirit became brighter and brighter, and the blade as thin as a cicada's wings emitted a chilling cold light.

After all the Yuan Artifacts were fused, Chen Xuan took out the many materials he had just selected from the ground and began to prepare to dissolve, these materials had been accumulated by the Danxuan Sect for many years, but at this time, Chen Xuan took out hundreds of them.

Every piece taken out is a priceless treasure, if the elders of the Danxuan Sect know that Chen Xuan can have so many materials at one time, they will definitely beat their chests in distress, these materials are enough even if they are refining eighteen top-grade Yuan Weapons, but the evil spirit is different from other Yuan weapons, the capacity he needs is huge, and of course the power is also huge.

All kinds of handprints flew out of Chen Xuan's hand, these were all obtained from that refining technique, it was very easy to refine at this time, otherwise if he wanted to refine the Dao weapon, Chen Xuan would have to find a new refining technique.

The blade of the knife is more and more light, the evil breath continues to erupt, the aura of Shura exudes a ghostly red light from the blade, and the phantom of the Shura appears from time to time, and the breath of ** begins to form slowly.

Reaching out and touching it again, the cold chill eroded his body again, Chen Xuan casually picked up the iron pestle that emitted the two heavens of ice and fire just now, and began to make hand prints, wanting to melt into the evil spirit.

At this time, a strange thing happened, no matter how Chen Xuan made a handprint, this material never moved, and there was no sign of dissolution, as if it was inviolable, no matter how Chen Xuan refined, he couldn't move a bit.

Immediately Chen Xuan became interested, what is this, why can't it be dissolved, Chen Xuan frowned.

This also aroused Chen Xuan's competitive heart even more, increased his strength, and more violent power emanated from Chen Xuan's body, and the terrifying realm of the peak of the earth spirit was immediately revealed, and with the increase of strength, the handprint changed from illusory to substantial, and hit the dark iron pestle again.

"Weng!"

A force suddenly rebounded back, and the inside of this iron pestle actually released a force that reflected back towards Chen Xuan, turning all the attacks into invisible.

At this moment, the black iron pestle seemed to be slowly falling off, and the blackened surface began to peel off, revealing a golden light, and soon, something similar to a key appeared in front of Chen Xuan.

"What is this?"

Chen Xuan took it in his hand and weighed it, feeling that the weight was still very heavy, and the feeling of ice and fire was still so strong.

"With the strength of his own earth spirit peak, he can't dissolve it, this must not be an ordinary thing, even the top-level yuan weapon can break it by himself, and this key-like iron pestle can't shake it at all!"

Chen Xuan said in his heart.

Throwing this iron pestle into a change, he once again took out other materials and melted into the evil spirit, and from his ring, Chen Xuan also took out a lot of resources and began to prepare for the final promotion.

After several days and nights of continuous refining, the evil spirit is finally about to reach the threshold of breakthrough, the blade has been tempered countless times, the endless formation is integrated into it, and those dissolved essences are all absorbed.

At this time, when I saw the evil ghost, I saw countless talismans flowing on it, the formation flickering, and there was a faint force of rules slowly forming, which was a sign that it was about to break through.

Don't dare to have any carelessness, the Shura Dan on the ground began to fly, what Chen Xuan needed to do was to strengthen the machine spirit again, only a powerful machine spirit could make the evil spirit exert more super power.

The Shura Pill from above on the ground began to fly, turning into a torrent of elixirs and flowing into the evil spirit.

After absorbing these Shura Dans, the Shura intent exuded was even stronger, and streams of killing intent emanated from the evil spirit, as if it was a bloodthirsty demonic beast.

After being infused with Shuradan, the momentum of the evil spirit has also evolved from violent to gloomy, ruthless, and killing, not the feeling of only evil, it seems that these are directly related to Shuradan, affecting the quality of the evil spirit.

After tens of millions of Shura Dan entered the evil spirit, they saw that the phantom inside began to close their eyes, and the machine spirit actually knew how to cultivate.

Chen Xuan's face was happy, if the instrument spirit could cultivate independently, then he would be able to save the time of refining in the future, as long as there were enough materials, the evil spirit would be able to improve his own quality.

Now that all the procedures have been completed, all that remains is condensation, only through continuous condensation, through continuous polishing, let the evil spirit exert his unique system, and even stimulate all his instincts.

The Dao talisman appeared from Chen Xuan's hand, and through the technique, Chen Xuan condensed a lot of talismans, and then entered the evil spirit, so as to do the second refinement.

The palm print entered the evil spirit very rhythmically, and a black spot the size of a grain of rice began to slowly appear from the inside of the evil ghost's knife body, which is what he wants to create space, and only the yuan weapon with space can have the opportunity to become a Taoist weapon, and even a lot of Taoist weapons can also be stored.

Time was passing silently, and I didn't know how many days had passed, so Chen Xuan was endlessly purifying and making the final plan.

Finally, after condensing for a few days, the evil spirit began to react, and a buzzing sound began to be made inside, and then the evil spirit began to vibrate continuously, and a trace of the power of the rules melted into the evil spirit at this time.

The surging power began to be released from the evil ghost, and it was only at this time that Chen Xuan breathed a sigh of relief, and he was finally about to take the last step, and only the last step could become the best elemental weapon.

The king's qi in the inner pill of the Flying Demon Tiger on the handle of the knife was all drained away by the evil ghost at this time, and the evil spirit at this time also exuded a king's might, and the feeling of contempt for the world was also reflected in the evil ghost's body.

Tiger roaring mountain forest, that is the spirit of the king, the evil spirit at this time is this heroic domineering, exuding a terrifying aftermath, making the enemy without a fight.

After accumulating to the top, the evil spirit finally began to climb, and the runes began to circulate on the blade, and the loach-like lines seemed to be alive, emitting a faint red light.

"Whew!"

A sword shot out from above the evil spirit, and the blazing sword slashed towards Chen Xuan, making a sneering sound, igniting the space and burning a stream of flames.

"Snort!"

There were two sounds again, and when he saw this sword mangs flying towards him, he pinched it casually, and it was a palm print, which knocked this sword mangs away, and the evil ghost actually joked with Chen Xuan, and after being promoted to the best yuan weapon, the evil ghost began to have a strong spirituality, and he was already able to recognize the master by himself.

The evil charm is complete, the martial arts have begun to comprehend a vague concept, the Nine Heavens of the Crane Dance has been fully established, the Ao Yi Slash has also been comprehended, not to mention the formation, this retreat is a successful end.

The improvement of the realm brought Chen Xuan not only an improvement in strength, but also a comprehension of the whole, and a new understanding of his own path.

The time when he came in Chen Xuan roughly estimated that it had been sixty or seventy years, and the more the cultivation reached the end, the longer it would take, and he didn't expect that this retreat would take him so long, but fortunately, the time here was a hundred times that of the outside, and it had only been a few years outside.

The evil spirit was once again put into his body, and he found a new set of clothes to put on, at this time, Chen Xuan's body was light and restrained, and he couldn't see that he was a strong man at the peak of the earth spirit, but the powerful people could still see it at a glance.

Releasing the signal, Chen Xuan glanced around, originally wanted to go and see where those Danxuan Sect ancestors were placed, but after thinking about it, it was better to forget it, not to mention those powerful prohibitions, even if he could break these prohibitions, it was also disrespectful to his predecessors.

Chen Xuan didn't have the heart to take the remaining materials away, but the iron pestle that released the two different breaths of ice and fire Chen Xuan put it away, because Chen Xuan vaguely felt that this thing was extraordinary, although he didn't know what it was for the time being.

A transparent passage appeared again, and Chen Xuan knew that it was a signal from outside that he had received a signal to go out, opening the tunnel of this space, and then Chen Xuan's body disappeared here.
