For being able to properly handle the merger of the senior brother of the boxing sect, Gu Yan can be regarded as a stone in his heart, after all, he is the patriarch of the Gulong clan, and he has to be responsible for more than 10,000 clansmen, and not let down more than 200 senior brothers, which is naturally not an easy matter.

For such an arrangement, it not only avoids some unnecessary troubles, but also can better develop the ancient dragon tribe, which is a good choice for everyone.

However, at this time, the ancient dragon tribe is very busy, especially the dancer and others, in order to meet the promotion conference of the ancient dragon tribe after January, it is necessary to prepare a lot of things, so the entire ancient dragon tribe can be said to be busy.

However, Gu Yan, the patriarch, was an exception, as early as after the meeting that night, Gu Yan entered the underground cultivation room alone to retreat, and the other things were all busy with the dancer, Qin Shan, Zhong Li and others.

For today's Gu Yan, the top priority is not to break through the cultivation, it can be said that the cultivation of the Gu Yan is already extremely shocking, only at the age of seventeen, he is already the realm of the fifth layer of the Wuwu Yuan Realm, this is definitely a genius among geniuses.

Moreover, Gu Yan's combat power is even more perverted, with the cultivation of the fifth layer of the Wuyuan Realm, he can fight against the masters of the condensation period, and he can win the battle steadily, this qualification, this ability to fight against the reverse level is not unique, but it is definitely very rare.

Therefore, the Guyan retreat was not for the purpose of improving cultivation, but for refining the elixir and refining the body refining holy pill - the Dragon and Tiger Bone Strengthening Pill. Although the Dragon Tiger Bone Strengthening Pill was a mid-level elixir of the spirit level, for Gu Yan today, the difficulty of refining it was no longer an obstacle.

A few days ago, Gu Yan had already tried to refine the spirit rank elixir, and he had successfully refined it, with his soul talent and perverted comprehension ability, Gu Yan had already stabilized the success rate of refining the spirit rank primary pill at more than seventy percent after refining it a few times.

It is Ghost Ku, a former demon hero, even a character who has seen alchemy masters, and he admires Gu Yan's alchemy talent so much.

Such a perverted comprehension ability, the incredible success rate of alchemy, this is absolutely unprecedented, and it would be a bit condescending to call it a genius. But there is no way, who called him to have such a demonic talent, if he has talent, he can be willful.

There is also a reason why he is refining the Dragon and Tiger Bone Strengthening Pill, because Gu Yan is taking the martial arts path of dual cultivation of the Demon Dao, although the cultivation of the "Great Five Elements Technique" is quite smooth, but the cultivation of the "Demon God Transformation" has encountered obstacles.

"Demon God Transformation" was created by a demon emperor with a great prestige, this emperor's fame is not inferior to that of the Blood Demon Emperor, and when you cultivate "Demon God Transformation" to the third level, you can cultivate some of the powerful secret techniques attached to it.

However, cultivating these secret techniques is not easy, and one of the most demanding conditions is that the physical defense needs to be at least comparable to that of a spirit-level primary crystal. However, although Gu Yan had spent a lot of effort in refining his body, after all, his realm was too low, so he still did not meet the cultivation requirements.

This is not to blame Gu Yan, because under normal circumstances, only the people of the Demon Clan at the peak of the condensation stage, or even the Jindan stage, can cultivate the Demon God Transformation to this realm, but Gu Yan's comprehension ability is too strong, and under the situation of the fifth layer of the Wuyuan Realm, the exercises have already broken through the triple level.

Now if you want to go further in the cultivation of "Demon God Transformation", it is necessary to step through the threshold of insufficient physical defense, but it is easy to say, and the breakthrough in physical fitness requires accumulated cultivation and strengthening to achieve.

And the physical defense has reached the level of the mortal-level high-grade crystal, if you want to break through this bottleneck and make a qualitative leap to the level of the spirit-level crystal, for most people, in addition to continuous strengthening, if there is no external force, under normal circumstances, it is difficult to achieve, at least it is absolutely impossible to achieve it quickly.

Therefore, for Gu Yan, the top priority is to refine the Dragon and Tiger Bone Strengthening Pill, and the cultivation of today's ancient saying also requires the Dragon and Tiger Bone Strengthening Pill. Although the body of the demon spirit is powerful, it is a demonic talent that is only reflected in the absorption and cultivation of demonic energy.

It didn't help much for physical defense at all, but Gu Yu didn't bother to concentrate on refining the body, and Gu Yan was not far from Gu Yu to endure the pain of refining the body, so naturally, the Dragon Tiger Bone Strengthening Pill became the best choice.

The elixir for refining the Dragon and Tiger Bone Strengthening Pill is now all available in the Void Tower, and there are quite a few of them. These elixirs are just rare, and they are not heaven and earth spiritual objects, so under the birth of Xiaobi, the growth rate has been accelerated by nearly fifty times.

This is not only because of the stronger function of Xiaobi today, but also related to the dense and misty Heaven and Earth Yuan Qi in the Void Tower, due to the last super barren stone vein, not only two medium-grade barren stone veins have been formed in the Void Tower, but all the Juyuan formations have also been devoured by a lot.

So that the Heaven and Earth Yuan Qi in the entire Void Tower does not have to worry about weakening in the next few decades, the rich Heaven and Earth Yuan Qi is undoubtedly a heavenly holy place for the elixir growing inside.

But this is not the most pleasing thing about Gu Yan, compared to how many elixirs, no matter how high the level is, how rare it is, it is not comparable to Xiao Bi's status in Gu Yanxin.

The rich vitality of heaven and earth has greatly accelerated Xiaobi's growth rate, and now Xiaobi's tree is nearly ten meters high, with lush branches and leaves, like a giant umbrella, and the same is true for the Fire Spirit Holy Fruit, which is now able to spit out some simple words.

However, Gu Yan was not at all worried that the Xukong Tower would inhibit Xiaobi's growth, which Ling Zun had long expected, the fourth layer of the Void Tower was the largest among the four-story towers, and the spatial height was also the highest, with thousands of meters, unless Xiaobi was already comparable to the spirit clan's psychic treasure tree, otherwise it would definitely not be suppressed.

After preparing everything, take out the alchemy great tripod obtained from the Lingzun Secret Realm, this great tripod is an extremely rare king-level high-level tripod-type crystal, even if it is more than enough to refine the emperor-level primary pill. Gu Yan's current strength is also qualified to be reluctantly used.

The Dragon Tiger Bone Strengthening Pill is not like an ordinary spirit level intermediate pill, if it is an ordinary spirit level intermediate pill, the two Yi Ding can also be refined, but the Dragon Tiger Bone Strengthening Pill has extremely high requirements for the flame temperature, which is comparable to the temperature of refining some king-level pills. The flame formation in the Liangyi Ding could not meet the requirements of refining at all.

That's why Gu Yan decided to use this king-level Danding, because this Danding was engraved with a formation created by Ling Zun - Stacked Yuan Array. This formation is extremely special, it can superimpose the true elements injected by the alchemy, so that only a very small amount of true yuan needs to be consumed to be able to urge the formation and refine the elixir.

For alchemists, this formation is undoubtedly a huge boost, especially when refining some extremely high-grade pills, the requirements for the alchemist's true yuan are almost harsh, but after having this formation, there will be no such worries.

Soon, after Gu Yan made some preparations, he looked at the elixir that had already been prepared in front of him for refining the Dragon and Tiger Bone Strengthening Pill, there were nearly thirty kinds in total, except for the extremely rare elixir that only had the effect of four or five hundred years, the others were some high-grade thousand-year-old elixirs.

Sitting cross-legged, looking at the Danding in front of him after it became smaller, a crimson flame appeared in Gu Yan's hand, and at the same time, a True Yuan Law Seal was punched, which was instantly injected into the Ding, and the formation in the Danding was immediately urged, and in an instant, the temperature around Gu Yan rose sharply because of the Danding.

"Withered Yuan Grass, Iron Papaya, and Bone Grass are first quenched with fierce fire, and the blood bone jade and joint vine are refined into liquid ······" According to the record on the Dragon and Tiger Bone Strengthening Danfang, Gu Yan put the elixir into the Danding in turn.

Each ancient rock was placed very carefully, although he did not lack these elixirs, but he had such an attitude towards alchemy. Even if he had refined a mortal-rank intermediate pill hundreds of times, he was never careless, and he had to be careful with every step.

Gradually, there have been nearly twenty elixirs put into the Danding by Gu Yan, according to the records on the Dan Fang, a furnace of Dragon and Tiger Bone Strengthening Pill can produce up to eighteen pills, but under normal circumstances, it is between twelve and twelve.

The last ten elixirs all need to be put in all at once, as it doesn't take long to quench the impurities completely, which is also the most critical moment.

The difficulty of refining the Dragon Tiger Bone Strengthening Pill is not very difficult, because the elixirs he needs to refine are all similar in attributes, and there is no problem of conflicting attributes. However, Gu Yan didn't dare to be careless in the slightest, because these elixir essences were smelted into pills, which required the power of the soul to be completely controlled.

And the key to determining the quality of the pill lies in this, this is the experience that Gu Yan has summed up in his long-term alchemy, so every time he is in the pill, he always has to be careful and careful.

"At the critical moment, this seat has worked hard to find and cultivate the elixir, and the long-awaited dragon and tiger must not fail!" Gu Yan silently hinted to himself in his heart.

The two clusters of red elixir essence began to slowly merge with each other under the control of Gu Yan's soul power, and at the same time, Gu Yan also increased the injection of true yuan, and suddenly the surrounding temperature rose again, but Gu Yan didn't feel the slightest, because he was devoting himself to alchemy.

Slowly fuse, complement each other's medicinal properties, and transform into a pill, which seems simple, but it is an extremely long process, and every moment requires the power of the soul to control the elixir essence to roll, so as to facilitate the fusion to the best degree.

At this time, the liquid medicine had been fused for nearly a quarter of an hour under the control of Gu Yan, and finally reached the standard of Ning Dan, and slowly, it began to separate out more than a dozen small liquid beads, that is, the liquid medicine that was about to condense into Dan.

Then, Gu Yanxin was stunned, seeing that the alchemy was almost over, he shouted lightly, "Out." In an instant, twelve ruddy pills were suspended in front of Gu Yan, and each pill seemed to have a reddish halo around it, but it did not emit the slightest aroma of the pill, and Gu Yan was a little puzzled.

"Why is there no Danxiang? Could it be that Ben Shao's refining failed, or there was a problem with the dispensing, and why is there a red halo. Gu Yan muttered to himself puzzled, took out the Dragon and Tiger Bone Strengthening Pill Formula, and then compared the elixir he had prepared, there was nothing wrong.

But he was very suspicious of this furnace of elixir, because the elixir he had refined before all emitted a scent of dan, and it was also recorded on this dragon and tiger strong bone pill that there would be a supernatural fragrance after the pill.
