"The gōng fǎ of his xiū liàn is rumored to require the person to automatically retreat after breaking through to the emperor realm, and then start to re-enter the emperor realm from the beginning of the immortal king realm, so that after retreating eight times, the ninth time he re-enters the emperor realm, it can be regarded as a complete entry into the emperor realm, and at this time, his realm will be extremely stable, and at the same time, his combat power will also be extremely strong, it can be said that every time he retreats, his combat power in the same realm will increase by one point." Wu Jin Songdao.

Du Yunfeng raised his eyebrows and said, "In this way, the top of the Immortal King List is really a not simple character, but I don't know how many times he has retreated now?" ”

"It's not clear." Wu Jinsong shook his head slightly.

"By the way, Brother Wu, do you know that there is a black market around here?" Du Yunfeng said.

"Black market? Yes! After all, this is a place of exile, compared to the outside, it seems to be very chaotic, as soon as the chaos appears, there will be disputes, there will naturally involve interests, interests always need to be digested, and this black market that digests interests naturally came into being, it can be said that there is a black market in the three cities of heavenly punishment, heavenly chase, and heavenly redemption, but the time for the black market to really start operating is very small, the black market operation of the heavenly punishment city is once every three months, the black market operation of the heavenly city every six months, the black market operation of the heavenly redemption city every nine months, Legend has it that the operation of these three black markets is exquisite, and their interest chains are very wide-ranging, by the way, what does the black market do? Wu Jinsong said.

Du Yunfeng said: "I want to dispose of these two weapons, and then buy some immortal materials for forging immortal weapons, and then forge a weapon in the near future." ”

As soon as Wu Jinsong saw Wang Pojun's broken saber, his heart suddenly understood, and then he said: "If you want to dispose of it in the black market, it is difficult, because the black market has not been operating recently, so I will help you digest it!" ”

Du Yunfeng groaned slightly, and said: "Forget it, brother, you help me digest it, it's a risk for you, or I'll digest it myself!" ”

"You don't know the place in this life, how do you digest it? Don't worry, I'm here to digest this, and the risk is not great, after all, I've been here for a long time, and this bit of concern is still there. Wu Jinsong said.

Du Yunfeng smiled faintly, he thought that the other party's words were still watery, mainly to comfort him, he naturally would not agree, if that was the case, he felt that it was equivalent to trapping the other party.

Du Yunfeng said: "Don't worry, brother, there is no need for this, I originally wanted to exchange these two weapons for immortal materials, but now I am ready to directly refine these two weapons, and then refine the required materials from them to forge my weapons." ”

Wu Jinsong said: "Since this is the case, then forget it, but if you need any immortal materials, just tell me, I am very familiar with this place, and I know whether there are any immortal materials you mentioned here, and if so, where are the immortal materials you need to sell." ”

Du Yunfeng said: "It's easy to say, it's easy to say, I'll go back and prepare, if I need anything, I'll tell you." After Du Yunfeng left, he quietly returned to the house, but he did not alarm any monks.

After arranging several formations in the room, Du Yunfeng thought that no matter what he was doing in the room at the moment, the outside would not notice the presence of monks in the room he was in.

At that moment, Du Yunfeng first performed the "doppelganger technique", and two more of him appeared in an instant.

One of these two clones used the Northern Xuan Immortal Fire to refine the Broken Saber, and the other used the Zhengyang Immortal Fire to refine the Black Magic Stick, while his deity used the Blue Wave Immortal Fire to refine the Yunyang Immortal Stone.

Gradually, Yunyang Immortal turned into a white liquid, and under the rapid patting and pinching of Du Yunfeng's hands, the liquid Yunyang Immortal Stone gradually turned into the shape of a sword.

At this time, Du Yunfeng had already extracted a golden substance from the broken saber, this golden substance was the essence of the broken saber, which had a large number of attributes of the Broken Blade Divine Stone, if it was added to the sword embryo transformed by the Yunyang Immortal Stone, it would strengthen the sharpness and hardness of this sword.

At the same time, Du Yunfeng's other doppelganger also extracted a cloud of black matter from the black magic wand, which had a large number of attributes of the Illusory Gang Magic Stone, and if it was added to the sword embryo transformed by the Yunyang Immortal Stone, it would strengthen the solidity and transformation ability of this sword.

Normally, this Illusory Gang Demon Stone is a magic material, and it is an excellent material for forging magic weapons, and under normal circumstances, there will be no immortal cultivators who use it to build their own fairy swords.

After all, the immortal sword made with this thing has a demonic energy, which will make other immortal cultivators hostile and look down on it.

There are even other far-reaching implications.

And Du Yunfeng's forging of the Immortal Sword with this black substance is actually no different from forging this sword with the Phantom Gang Magic Stone, and the adverse effects exist.

The reason why Du Yunfeng was not afraid was because after comprehending the "Immortal-level Forging Treasure Book", he had already mastered how to remove the attributes that were unfavorable to him while retaining the good attributes of the magic material such as the Phantom Gang Magic Stone.

As Du Yunfeng's two doppelgangers sent the golden substance and the black substance to the deity, the deity put out his palms together, fusing the two substances into one, and then constantly slapped the mixed substance in front of him, and each time he slapped it, the demonic energy contained in it would be one point less.

Du Yunfeng's shot was very fast, and he slapped thousands of palms in an instant.

As traces of demonic qi floated out, Du Yunfeng's clone immediately turned it into nothingness with Zhengyang Immortal Fire.

Gradually, there was no trace of demonic energy in the substance in front of Du Yunfeng, and Du Yunfeng immediately smashed it into the sword embryo and began to beat it again.

Although his forging is different from normal forging, the effect is out.

When Du Yunfeng completely fused the Yunyang sword embryo with the black and gold mixed substance, it could be seen that two different lines appeared on the white sword body, black and gold.

Among them, the golden dragon and the black tiger seem to separate the two substances, but their characteristics are completely integrated into the sword, making this fairy sword that has not yet finished the process perfectly possess the characteristics of the three materials of Yunyang Immortal Stone, Broken Blade Divine Stone, and Phantom Gang Magic Stone.

In the end, Du Yunfeng spewed out a mouthful of his innate essence qi at the fairy sword, made it smaller, and put it into his own golden room to raise it.

"This sword is infused with demonic materials, for immortal cultivators, this sword is undoubtedly more lethal than other immortal swords, and it is just used to deal with the guys in the immortal world who want to deal with me." Du Yunfeng said secretly.

Then Du Yunfeng sat cross-legged directly, no longer passively raising the sword, but taking the initiative to raise the sword.

In this way, the final shape of the sword is accelerated.

If it is passively warmed, it will take three days for the sword to be forged.

And now Du Yunfeng took the initiative to raise it with a secret method, but the refining time was shortened to one day.

When this sword is truly refined, the power of its first explosion will be huge, and Du Yunfeng is still quite looking forward to the scene at that time.
