Although Pei Xinyan and Nalan Ruoyan didn't know anything about the Dan Dao, they had heard of the anti-heaven pill like the Infant Returning to True Pill, and it had also disappeared for thousands of years in this Tongyun Domain, and they actually found the Dan Fang here.

In the records of the sects, whether it is the Sword God Palace, the Lingxiao Palace, or the Yuyu Palace, they all respect this elixir, and it is very difficult for idle monks to see it, and it was a rare thing in all major sects thousands of years ago.

Lin Tianxu looked at their expressions and naturally knew the preciousness of this Infant Returning True Pill, "What? Isn't it that one of you will refine it? He asked them first.

A look of embarrassment appeared on Hulan He's face, "It's just that I've seen this elixir in the classics, not to mention such an anti-heaven elixir, even if it doesn't enter the stream, I can't refine it." He looked at the two women with a blank look.

Seeing that Bei Xinyan and Nalan Ruoyan both shook their heads, then the three of them looked at Lin Tianxu with hopeful eyes, if they could refine this elixir this time, they would not be able to enter the innermost, and they would have gained a lot of money!

Bei Xinyan, who was in love, naturally felt that his Senior Brother Lin was omnipotent, and at this moment, even Nalan Ruoyan had a faint feeling in her heart, although such an anti-heaven thing must be very difficult, but Lin Tianxu would definitely have a way.

Looking at their expressions, Lin Tianxu understood that it was still up to him, but having the opportunity to refine such an elixir and obtain such a pill was a very important thing for the various sects in the Tongyun Domain now.

Most of the disciples of the Sword God Palace are between the Cave Void and the Mahayana, and the senior brothers of the Jade Sect in the palace are only in the middle of the Mahayana period, so the effect of this elixir that helps break through the tribulation can be imagined for the various sects.

Although I don't want to let outsiders know all the hole cards, it is the right thing to do, but at the moment no one can, then only I can reluctantly undertake this task, the ability is too strong, it will indeed be very tiring.

Seeing that Lin Tianxu was silent, Hulanhe couldn't help but ask, "Is there no way for Senior Brother Lin?" "If you see the golden mountain in front of you but can't reach it, it will make everyone very depressed.

"I haven't seen such an elixir before, not to mention that there are three materials left here, and I don't know if there is any original medicinal effect for such a long time, if you don't know, I can only try my best." Lin Tianxu involuntarily touched his nose again.

Although he was very uncertain, Nalan Ruoyan and Hulan He settled down at once, looking at his stinky fart at the moment, Bei Xinyan had a sense of crisis, because at this moment Nalan Ruoyan's eyes were becoming more and more strange when looking at him, it was difficult for this disciple of Lingxiao Palace to pay attention to a man like this.

Of course, Bei Xinyan wants his senior brother to be proficient in everything, but he can only let himself know, and the reason is of course obvious! People are selfish creatures, and it is easy not to share with others.

After they stood far aside, Lin Tianxu began to check the raw materials on the table one by one, although most of them were herbs that he didn't know, but Lin Tianxu, who had a lot of experience, just pinched it, and then broke it and smelled it, and he had a rough idea in his heart.

Pills and formations have a common law, but pills are herbs with different effects, take their special ingredients and then produce wonderful changes in the process of refining, artificially create some special effects, alchemy or the key is to have a full understanding of the herbs, and do a good job of research on the pills.

In the previous years in Shangyun Danzun, the impact on Lin Tianxu was really very great, just like now, although many medicinal materials were not seen by himself, but after distinguishing for a while, Lin Tianxu began to meditate on the key to this elixir.

Unlike Bei Xinyan, who looked at the quiet Lin Tianxu with a stupid gaze, Nalan Ruoyan's gaze was just a casual glance over the man not far away, his kind of explosion and disregard for death during the battle was in great contrast to the quiet frowning from time to time at this time, but why did he pay more and more attention to him?

Formation and Dan Dao are both very advanced knowledge, even among some of the predecessors of the Tongyun Domain, it is difficult to find someone who is proficient in both at the same time, and even if there is such a thing, it will naturally affect their cultivation.

Therefore, Lin Tianxu, who was outstanding among his peers in his cultivation and would leave everyone behind faster, actually had such profound attainments in the formation and Dan Dao, how old was he? It's just a little bit bigger than yourself! How the hell did he do it?!

Even the Hulan River, which usually thinks highly of himself, is a young monk with a great reputation in the Tongyun Domain, and feels that the longer he stays with Lin Tianxu, the more he will sigh to himself, not only the cultivation realm, not only the combat ability, but even the formation and Dan Dao, which are 108,000 miles away from young people, have been studied?!

Lin Tianxu naturally didn't know that he had been quietly exploring Danfang in a short time, and there were such big ripples in the hearts of several people over there, if he knew, he would probably smile faintly, is this difficult? I knew it many years ago, okay, the famous disciples of the upper realm are still making a big fuss about this matter

Blame?! Cut!

It is worthy of being a high-grade elixir, and the medicinal materials needed are also extraordinary, although I don't know how many years have been spent in this dark room, but most of the medicinal properties have been retained, and the only problem is that there are only three materials, which is really a big test.

In previous years, Lin Tianxu had to waste a lot of materials to understand the key to each material, so as to refine it smoothly, so he had to prepare everything completely now!

Putting down the medicinal materials in his hand, Lin Tianxu's hands touched this cold medicine tripod, his qi and fire alchemy technique can already be called proficient over the years, and the control of true qi has also reached an amazing degree with the growth of his cultivation, at this moment, he feels this obviously high-grade medicine tripod, and the aura in his hand has been dispersed into it.

The three people who had been watching Lin Tianxu's every move, seeing that he had just held this medicine tripod with both hands, and in a blink of an eye, flames rose from the tripod, and the flames that were not dazzling looked so comfortable, what is this? The legendary primordial flame?

After becoming familiar with this medicine pod, Lin Tianxu buried his head in these dozens of herbs, and occasionally even broke off a little bit of chewing, and wrote down all the things he needed while thinking about it.

The tedious preparations lasted for many days, and Lin Tianxu did not rest during the whole process, he was doing the things at hand calmly, it seemed that everything was in order, Nalan Ruoyan did not close his eyes and meditate these days, always paying attention to his progress, and sweeping his cheeks from time to time.

There are many kinds of materials, and it is even more troublesome to understand and distinguish them than to break the formation before, and after more than a month, Lin Tianxu finally stopped all his movements, pondered quietly for a while, and began to sit cross-legged on the ground to adjust his state.

Seeing his appearance, he knew that the preparation for refining the pill had been completed, so whether he could succeed in the next step depended on his ability, Bei Xinyan was convinced that Lin Tianxu could refine the Infant Returning Pill to the Truth, Nalan Ruoyan? I think so......

It took a whole hour for Lin Tianxu to adjust his mood to the best, when he opened his eyes, his eyes were full of confidence at this time, and as he grew up, a momentum that was bound to be won was exuded at once.

At this moment, Lin Tianxu's eyes were raised, dozens of medicinal materials had already floated to his body, he breathed steadily twice, stretched out his hands to hold the side wall of the medicine pod, and as the flames rose, the first medicinal herb had already floated into the medicine pod.

The previous process was the same as the one he had simulated many times in his mind, as he roasted with a properly controlled flame, all the herbs turned into condensed medicinal juices in order, and then began to be mixed and reheated according to different needs.

The extraction of useful things to condense the juice went smoothly, and as time passed, soon dozens of medicinal herbs turned into condensed juice, and began to continuously fuse and react, until the last fist-sized black medicinal juice finally formed in the Great Ding.

From beginning to end, Lin Tianxu was engrossed, and he didn't dare to blink his eyes at this moment, the most critical moment of alchemy was coming.

As the qi and fire began to strengthen, the Dan liquid began to drip and swirl in the ding, and the speed of rotation became faster and faster, and the color on it began to gradually change, and the black juice began to appear grayish-white, and gradually became yellowish.

Just when he saw that there was a danxiang forming, suddenly there was a snort on the unformed pill, and then a scorched green smoke rose, and Lin Tianxu, who was about to succeed, sighed secretly in his heart, frowned slightly, took the burnt elixir in his hand, and sniffed it slowly.

His own heat is well controlled, he has refined too many pills before, Lin Tianxu is very sure of this, it must be something wrong when he dispensed the medicine before, and if he didn't match the medicinal juice according to the strict quantity, the current situation would happen.

Lin Tianxu completely broke the burnt pill, scraped off a little bit and tasted it in his mouth, and then picked up the pill again and began to look at it carefully, because there were only two ingredients at the moment, and he had to be more cautious.

After thinking about it in his heart for half an hour, Lin Tianxu breathed a sigh of relief and started a second attempt.

After removing the slag, pure juice, fusion, and carefully confirming that the amount of each material is just right according to the requirements of the unilateral side, the final Cheng Dan began, although the preparation is more sufficient, but it is still turned into fly ash when it is formed, how can this be? !

Lin Tianxu also frowned at the moment, completely in accordance with Danfang's requirements, and the fire control was also perfect, how could it still fail?! Bei Xinyan and the others looked at Lin Tianxu's eyes and began to worry, after all, there was only the last bit of material left at this time, but they couldn't miss it again!
