Wen Feng said with envy: "As I said before, Immortal Demon Island is a place where fish and dragons mix right and wrong, but because of its special geographical location, the genius treasures of the Luo Tian Continent are all gathered here, and the Immortal Demon Banquet is the world's top auction. ”

"No wonder this is the case, the Immortal Demon Island gathers all races, and the treasures of all races are brought here." Yan Xu said suddenly.

"The Western Earth Demon Territory, the Southern Heavenly Demon Domain, and even the unique spirit grasses, ores, and divine weapons left from places such as the Northern Star Continent and Ice Pole Island in ancient times, etc., if you can imagine it, you will definitely be able to find it on the Immortal Demon Island, it just depends on whether you make the starting price." Wen Feng shook his head and talked eloquently, although he had never participated in the Immortal Demon Banquet, he had been to Immortal Demon Island a few times, and he was no stranger to the strange stories of this place.

Yan Xu looked at the golden jade in his hand, shook his head and smiled: "According to what you say, all the people who participate in the top auctions are people who spend a lot of money. I don't have anything of value to auction, and I don't have many spirit stones to squander, so how could I suddenly give me an invitation. ”

Wen Feng felt a little strange about this, and quipped: "Maybe the other party learns about the Ancient Dan Fang in the hands of Master Yan, or the profit sharing of your cooperation with the Medicine King Palace, its potential should not be underestimated." ”

"Although the income of Haoqi Pill is high, it is just a pill after all, where can it be compared to the Medicine King Palace. Even if it's the Medicine King Palace, isn't it as long as your hall master has been invited to participate? Yan Xu asked rhetorically.

"This ...... That's just as well. If Master Yan doesn't plan to go, it would be a pity. Wen Feng shook his head, glanced at the golden jade in Yan Xu's hand again, and said with regret: "There are two kinds of invitations to the Immortal Demon Banquet. One is a silver jade, which can be accessed regardless of name or identity, as long as you have it. The other is the golden jade, which can only be visited by the invite. ”

Yan Xu flipped over the golden jade, and sure enough, there was a line of small characters at the bottom, engraved with the words 'Tianhao Sect' and 'Yan Xu'.

"This Immortal Demon Banquet will be held a year later, so Master Yan doesn't need to make a decision in a hurry." Wen Feng said, and then did not mention this topic more.

After Yan Xu counted the spirit grass, he got up and said goodbye and returned to his residence alone.

After returning to his residence, Yan Xu took out a Qiankun bag and picked out dozens of spirit grasses, preparing to refine a batch of pills by himself.

In the past, Yan Xu was born with alchemy and refining weapons because of the lack of fire in the spiritual roots of the four systems of gold, wood, water and earth. However, since the spiritual root mutated into the Five Elements Dao Body, the Five Elements Spiritual Root of Gold, Wood, Water, Fire, and Earth has been completed, and the alchemy and refining tools are no longer barrier-free for Yan Xu.

During the retreat of Tianhao Sect, Yan Xu studied the art of alchemy when he had nothing to do, although the level was slightly worse than the purple cloud of the body of the Dan vein, but with the blessing of the sect's skills and architecture, the level far surpassed that of the alchemy masters in the outside world.

The counted spirit grass was placed on the table, Yan Xu took out a simple and rich medicine pod, and a scorching flame rose from his palms.

Under Yan Xu's control, the spirit grass was thrown into the medicine tripod in an orderly manner, and in the blink of an eye, it was quenched into a crystal clear liquid tumbling in the tripod.

According to the different medicinal properties of the spirit grass, Yan Xu poured the quenched medicinal liquid into a jade bottle for a while, and then continued to extract and refine other spirit grasses, and so on, and finally combined them into a furnace to refine into a pill.

In less than half an hour, Yan Xu had refined more than 20 bottles of Dingyuan Dan.

"Whew! The Dingyuan Dan with Danyun is only thirty percent, and sure enough, if you don't practice for a few days, your hands are a little rusty. Yan Xu rubbed his hands, and his results could only be regarded as unsatisfactory.

Refining nearly three hundred Dingyuan Pills in such a short period of time, and more than fifty percent of them have Dan patterns and thirty percent of them have Dan clouds, Yan Xu is not satisfied enough, if the people of the Medicine King Palace know a little, they will be so angry that they will smoke.

Such a perverted alchemy success rate and the best rate are probably only available to the Dan King, but it is just commonplace for the alchemists of the Tianhao Sect.

The pill was ready, Yan Xu took out dozens of top-grade spirit stones and put them beside him, hesitated for a moment and took out another fairy crystal, licked his lips and said, "I don't know what will happen if I forcibly absorb the fairy crystal with my current physique?" ”

The aura contained in the immortal crystal is not only a hundred times that of the best spirit stone, the form of its aura existence is fundamentally different, since assisting the Heaven Swallowing Rat King to survive the Heavenly Tribulation Thunder Punishment and accidentally absorbing a part of the aura of the immortal crystal, Yan Xu has always planned to try to absorb and refine the immortal crystal alone.

"Before, there has always been a shortage of fairy crystals, but now there is finally a chance." Yan Xu pinched the immortal spar in his hand, raised his head and took a dozen Dingyuan Pills and began to concentrate on refining.

If Yan Xu's method of refining the pill was astonishing, then refining the immortal crystal was crazy.

Immortal crystals, non-distraction period monks cannot be refined and absorbed. Its overflowing aura, even if it was just a trace of it, would break the dantian of the Yuan Infant Stage, and Yan Xu's initiative to refine the immortal spar was simply a suicidal move.

Yan Xu's eyes were slightly closed, and Zhou Tian was lucky, and as the Dragon Emperor True Qi moved, a vortex was formed with his body as the center, frantically and greedily absorbing the surrounding aura.

The fairy crystal was suspended in front of his chest, accompanied by the aura that slowly rotated and emitted a multicolored halo, and as soon as the aura overflowed, it was quickly absorbed into Yan Xu's body.

Originally, the immortal crystal aura that was supposed to be like a fierce medicine for the Yuanying monk was absorbed by Yan Xu, but after being absorbed by Yan Xu, he obediently swam into the dantian along the meridians, and strengthened Yan Xu's Yuanying one by one.

At the same time, the pure medicinal power of the Ding Yuan Pill dissolved in Yan Xu's body, but compared to the huge aura of the fairy crystal, the effect of more than a dozen Ding Yuan Dan was not surprising, and it was quickly absorbed by Yan Xu's greedy body.

When Yan Xu began to absorb the elixir and immortal crystal, the Phantom Saint Glass Dragon, which had been sleeping in the dantian, moved.

The little guy has a keen sense of smell, and happily swims around Yan Xu's dantian, absorbing all the massive spiritual energy.

The body of the Phantom Saint Glass Dragon seemed to be transparent, and the aura passed through its body, but it returned to Yan Xu's dantian in double amount.

Previously, Yan Xu took Dingyuan Dan like this, and now refining and absorbing immortal crystals is still like this. The only difference was that the originally fierce aura had been transformed into a warm and long aura by the Phantom Saint Glass Dragon.

Yan Xu was in a state of cultivation, clearly feeling every piece of flesh and blood, every wisp of spiritual energy, and every trace of divine consciousness in his body.

The endless stream of spiritual energy turned into mana, like a warm mountain spring soaking every inch of his body, and the cultivation realm was rapidly improving at an unimaginable speed.

Ordinary Yuanying cultivators may not be able to move the slightest barrier after several years of penance, and there is no ordinary here in Yan Xu, and his cultivation has soared at an unimaginable speed.

The immortal crystal stone is a high-grade immortal stone that can only be refined by monks in the distraction period, and the aura it contains is very amazing, and the effect of refining and absorbing by Yan Xu in the late Yuan Infant period is of course immediate.

The immortal crystal was only absorbed in a thin layer, and the dozen or so Dingyuan Pills under Yan Xu's suit had already been absorbed.

Taking so much Dingyuan Pill in one go, only a demon beast with an extremely strong body can survive it, but it is a drop in the bucket for Yan Xu.

This absorption and refining speed was even far beyond Yan Xu's expectations, and he couldn't help but secretly say: "Could it be that with the growth of the Phantom Saint Glass Dragon, even the absorption capacity has been strengthened?" ”

Yan Xu didn't think much about it, and quickly took out five bottles of sixty Dingyuan Pills, and poured them all into his mouth.
