A powerful Great Immortal Venerable, because of the Dao Saint Yuan Immortal Paw and the Spirit Demon Crystal, a short contact, the strange body died, and the Dao Ji was completely demonized into a magic crystal, such a strange scene, suddenly made all the surrounding Immortal Venerables panic and change color.

The magic crystal left behind after the fall of the Great Immortal Venerable, no one dared to touch it at all, and with the rolling demonic qi, it fell into the galaxy, gradually drifted down, and disappeared.

Those Tianzun upstream seemed to have known that this kind of thing would happen, and their faces were expressionless, just staring at the exit of the demon cave.

Not long after, another slightly smaller Dao Spirit Demon Crystal rolled out of the demon cave. This time, it was still the dozens of mid- and high-level veteran Tianzun who snatched it, and as for the low-level Tianzun, they could only pick up some missed small magic crystals in the midstream.

This time, no Immortal Venerable dared to snatch the missing magic crystals.

The fallen Great Immortal Venerable is a lesson from the past. If you don't comprehend the true laws of the Heavenly Dao, wanting to snatch the Dao Spirit Demon Crystal is tantamount to looking for death.

Wu Yanzi was also shocked by Fang Cai's scene, and was speechless.

To his surprise, Gu Yao Lao Dao, who was alchemizing pills on the side, seemed to see his doubts, and actually kindly divided part of his mind and told him about some Dao Spirit Demon Crystals.

"This spirit demon crystal was transformed by the demon blood of the dark demon clan that contained the power of the Heavenly Dao in its blood mansion after it fell after it was captured and imprisoned by the Heavenly Venerable Powers of the Hongmeng Immortal Realm in ancient times. Ancient cultivators, whether they are immortals in the Hongmeng Immortal Realm or creatures in other interfaces, if they cultivate to a certain realm, the bloodline or mana in their bodies will evolve into Origin Crystals. ”

Wu Yan nodded, indicating that he knew this, but he still listened very carefully to the things that Gu Yao Lao Dao talked about to him.

Even within the current Hongmeng Three Realms, after the immortals cultivate to the Great Sage Realm, the mana will also condense the Holy Spirit Crystal, and the predecessor of this Holy Spirit Crystal is the Yuan Spirit Crystal, the mana Yuan Crystal that must be condensed when the Great Luo Yuan Immortal.

Wu Yan is still in the realm of the Great Luo Ancestral Immortal, and when his cultivation reaches the late stage of the Ancestral Immortal, he will try to condense the mana Yuan Crystal, and once he succeeds, he will officially break through and step into the realm of the Great Luo Yuan Immortal.

It can be said that before the Yuan Immortal, the mana was scattered, and only when the Yuan Immortal realm was reached, the mana would truly return to the Yuan and be purified to the strongest state.

"In the Dao Spirit Demon Crystal, it contains the Heavenly Dao will of the Dark Demon Venerable before he died, and its realm has at least reached the realm of the Holy War Immortal, without the will of the Holy War Immortal, there is absolutely no chance to capture and refine these Dao Spirit Demon Crystals. That Great Immortal Venerable tried to capture that Dao Spirit Demon Crystal, but he never expected that the power of will contained in it directly destroyed his physical vitality, and even directly refined the mana of his body into a Dao Spirit Demon Crystal. ”

"In that case, why didn't those people snatch the magic crystal left behind by that fallen Great Immortal Venerable?" Wu Yan asked strangely.

A wry smile appeared at the corner of Gu Yao's mouth, obviously Wu Yan's question was too simple, which made him feel funny.

"Didn't you see that the Heavenly Venerable who won the Dao Spirit Demon Crystal was envied by many people when he returned? He should be grateful to the fallen Great Immortal Venerable, if it weren't for the stupid Immortal Venerable, he would have to spend a lot of strength to get rid of the Demon Dao Will in that Spirit Demon Crystal, and then he could absorb the power of the Heavenly Dao within it. ”

"In this way, when the Great Immortal Venerable grabbed that Dao Spirit Demon Crystal, he was tantamount to sucking the Heavenly Dao Will in that Dao Spirit Demon Crystal into his body?"

"That's right, the Dao Spirit Demon Crystal has been trapped in the Ancient Demon Tomb for countless years, and the vitality within it has long been exhausted, and the Demon Dao will within it, although it is not a real creature, still instinctively needs to replenish vitality. That Great Immortal Venerable went to give life to that Spirit Demon Crystal, wouldn't he die himself?"

Wu Yan nodded suddenly, and finally understood what was going on.

"What is the purpose of these Dao Spirit Crystals? Why are they all so crazy to scramble? By the way, why don't you grab them?"

Wu Yan is naturally referring to Gu Yao Lao Dao and Heaven Swallowing Demon Venerable.

"The Dao Spirit Demon Crystal is the crystals of demonic blood doubting mana left behind after the fall of the Demon Venerable, and it contains the purest power of the Heavenly Dao, and may even contain some specific inheritances. Tianzun wanted to continue to improve his strength, and he relied on cultivation alone to absorb the qi of heaven and earth, but the effect was negligible and negligible. They had to rely on absorbing the power of the Heavenly Dao in order to continue to improve their cultivation. However, in this world of bitter seas, the power of the Heavenly Dao is already limited, and some Heavenly Dao is not complete, and absorbing too much is harmful and useless. Only this spirit crystal is the cultivation thing that Tianzun needs most, just like the use of the source stone for immortals. ”

Gu Yao said to Wu Yan tirelessly.

"The juniors understand, thank you for the seniors. ”

Wu Yan nodded abruptly again and thanked Gu Yao Lao Dao.

At this time, when he looked at those Dao Spirit Demon Crystals that erupted from the Demon Cave, Wu Yan somewhat understood why those Heavenly Venerables were so crazy to snatch those Dao Spirit Demon Crystals, and those Great Immortal Venerables and Peak Immortal Venerables also wanted to get those Dao Spirit Demon Crystals.

The Heavenly Venerables need to improve their cultivation by absorbing the power of the Heavenly Dao in the Dao Spirit Demon Crystal, and the Great Immortal Venerables, if they want to break through the realm, they naturally need to absorb the power of the Heavenly Dao and impact the realm of the Heavenly Venerable.

For that Dao Spirit Demon Crystal, Wu Yan naturally couldn't have no ideas, but with his realm, it was naturally impossible to snatch the Dao Spirit Demon Crystal.

At the exit of the demon cave, every once in a while, there will be Dao Spirit Demon Crystals rushing out, large or small, and so on. The largest one is even seventy or eighty thousand zhang in size, and it is said to be the Dao Spirit Demon Crystal left by the Great Heavenly Venerable.

When encountering such a high-level Dao Spirit Demon Crystal appearing, the Heaven Swallowing Demon Venerable, the Sanqing Xuanzu, the Beidou Sword Venerable, and the Doutian Saint Venerable will snatch it, and the other Heavenly Venerables will naturally avoid the battle between the four of them very interestingly.

And the smallest Dao Spirit Demon Crystal, which is only 10,000 zhang in size, is said to have been left behind when the low-level Demon Venerable fell. This kind of magic crystal, the middle and high-level Heavenly Venerables will not snatch it, because the power of the Heavenly Dao contained in it will not help them at all.

At this time, it was time for those low-level Heavenly Venerables and Great Immortal Venerables to start snatching.

The Great Immortal Venerable naturally couldn't snatch the low-level Heavenly Venerable, but the low-level Heavenly Venerable obviously didn't dare to do things too well, and would leave some for the midstream Great Immortal Venerable and the peak Immortal Venerables.

In this way, outside the Demon Cave, it became a battlefield for a group of Heavenly Venerables and Immortal Venerables to snatch the Dao Spirit Demon Crystal.

It's just that everyone is very restrained, and there is no such thing as a big fight for snatching the Dao Spirit Demon Crystal.

Gu Yao Lao Dao and others had already proposed that this time they would go through the Great Wilderness Heavenly Road together, and if they put their lives here because of the competition for this Dao Spirit Demon Crystal, it would be too cost-effective.

After a few hours, more than twenty Dao Spirit Demon Crystals, large and small, rushed out of it.

Then, the demonic qi gushing out of the demon cave changed, the number began to decrease, and the demonic qi became thinner and thinner, and at this time, there were no more Dao Spirit Demon Crystals rushing out of it.

However, the absence of the Dao Spirit Crystal does not mean that there is no Demon Crystal.

In ancient times, it was not only the Demon Venerable of the Tianzun level who fell, but also countless Demon Venerables of the Immortal Venerable level, and after the fall of these Demon Venerables, the magic crystals left behind were the Holy Spirit Demon Crystals.

These Holy Spirit Crystals contain extremely pure Dao Saint Yuan, which is still of great use to Immortal Venerable, but it obviously has no effect on Tianzun.

Therefore, at this time, the Tianzun Star Lords stopped moving one by one, and sat quietly cross-legged beside them, watching the scene of those Immortal Venerables competing for the Holy Spirit Crystal Crystal.

The number of Holy Spirit Demon Crystals gushing out was naturally far more than that of Dao Spirit Demon Crystals, and in a few hours, tens of thousands of pieces were almost erupted from that Demon Cave.

After that, nothing spewed out of the magic hole.

At this time, the demonic qi spewed out from the demon cave was only slightly more than usual, and there was no other difference.

Experienced Venerables knew that this was the best time to enter the Ancient Demon Tomb.

However, everyone had already agreed that they would not enter together until three days later, when Gu Yao Lao Dao and Wu Yan finished refining the antidote pill for them, because although the time had come, no one entered first, but very consciously gathered to the planet where Gu Yao Lao Dao and Wu Yan were, and waited for the two quietly.

Gu Yao's old way alchemy is very different from Wu Yan's alchemy.

The technique used by Wu Yan in alchemy is still the same as the previous method of shaking the peak and becoming a spirit. The biggest advantage of this method is that the quantity of refining detoxification pills is very large, which is suitable for large-scale alchemy.

However, the methods used by Gu Yao Lao Dao are even more hidden. The Dan furnace was in front of him, he grabbed a banana fan in one hand, pinched the recipe in the other, and from time to time punched into the Nadan furnace one after another, or threw in something that others couldn't see clearly.

The whole process seemed to be mysterious, and it was impossible to figure out what kind of elixir he was refining and what method he was using.

However, everyone still focused their attention on the old Dao of the ancient kiln, wanting to see the origin of the Dan Dao of this old Dao.

Three days, for everyone, was not much worse than a blink of an eye, and it passed quickly.

With the help of the Great Array, Wu Yan's alchemy this time was much more convenient than in the independent space world condensed by the Heaven Swallowing Demon Venerable.

Because, that big array can not only provide a steady stream of Dan fire power for the seven Dan furnaces, but also provide him with a steady stream of mana and immortal power, he doesn't even need to deliberately recover, the mana and immortal power consumed in his body are all recovered with the help of the big array in the process of alchemy.

In three days, Wu Yan successfully refined all the nine kinds of detoxification pills in batches, and according to the list given to him by Gu Yao Lao Dao before, all of them were distributed to the Immortal Venerable and even Tianzun who needed these detoxification pills.

Although these people had already agreed with Gu Yao Lao Dao that they would not pay any remuneration, when they received the detoxification pill from Wu Yan's hands, which was several times better than they expected, they still willingly gave Wu Yan a lot of good things.

Under the difficulty of being enthusiastic, Wu Yan had no choice but to accept them all into his own small world. With this experience of alchemy, Wu Yan's prestige in the minds of Tianzun and Immortal Venerable has been raised a lot again.

After Wu Yan finished distributing the elixir, it didn't take long for Gu Yao Old Dao to finish alchemy, and all the Venerable Ones also successfully received their own elixir at Gu Yao Old Dao.
