After killing the Iron Crowned Dragon Eagle, Li Muchen searched the island and harmed many monsters before he began to explore the formation nodes here.

Approaching the formation node, Li Muchen confirmed the location, this formation node is one of the seventy-two nodes of the Earth Evil, it belongs to the auxiliary node, even if it is destroyed, it will not destroy the general structure of the formation, correspondingly, there are not too many resources and monsters nearby.

There is an ancient hall in the center of the formation node, which is closed at this time, and there is a formation guard. According to the custom, the ancient hall is opened every three days, and at that time, the demon beasts can also enter it and absorb the power of the ancient demon blood jade spread out inside, but the ancient demon blood jade itself cannot be moved, nor can it be destroyed, only the disciples of the Changqing Sect can take it out with special techniques.

One hundred and eight formation nodes, secretly combined with the number of Tiangang and Earth, are distributed in the forbidden place of the crypt by the wrong way, each formation node is an ancient hall, near the remote hall, the strongest demon beast Iron Crowned Dragon Eagle has been killed, and the remaining demonized demon beast big cats and kittens are two or three, unable to stop Li Muchen, when the local secret hall is opened, it is gathered here to deliver food to Li Muchen, just to make up for the previous loss on the Iron Crown Dragon Eagle.

And after the impurities, that is, the demonic qi, have all spread out, the real ancient demon blood jade has also been formed.

With the identity token, Li Muchen passed the blockade formation and entered the depths of the main hall.

The outside world is dark, but the inside of the ancient hall is bright and warm, an orange flame floats in the center, full of spirituality, and the breath is similar to the candle dragon formed by the ancient treasure before, and the pillar of light seen from the outside is here.

In the center of the flames, there was a red jade platform, facing the hollow on the top of the ancient hall.

The blood of the ancient demon spirit was sucked into the red jade platform through this channel, and then under the refining of the jade platform, the demonic qi also spread out through this channel and was absorbed by the nearby monsters.

Li Muchen's mana is injected into the identity token, forming a shield, this shield has average defense power, mainly plays the function of identity authentication, this token is bound to Li Muchen, outsiders cannot use it, and the sect's life card is inducted, once Li Muchen is fate, it will also destroy itself.

The floating flames seem to be mild, but they originate from the ancient candle dragon, and with the large array here, they can easily melt ordinary magic weapons.

In front of the identity token, the flame automatically retreated, revealing the red jade platform in it.

Li Muchen cautiously stepped on the jade platform, not as high as he imagined, but felt a little cold.

The various formations in the jade platform, Li Muchen knew a little, the formations attached to this high-level formation were naturally not ordinary, even if he didn't understand it very well, Li Muchen still forcibly wrote down the patterns in it, in case he encountered something similar in the future, he wouldn't know anything.

And the target of this trip, the Ancient Demon Blood Jade, is in the center of the formation, in a piece of diamond-shaped red blood jade, a few strands of silver silk threads can be seen on a closer look, this is the refined Ancient Demon Essence Blood.

"Is that all there is to it?"

Li Muchen was disappointed, four strands of silver filament, the size of a hair, and the length was only a few centimeters, and there was probably not a drop of ancient demon essence blood when he got it out.

"The previous ancient demon spirit blood should have been collected, this is newly generated after the last cleanup, plus this ancient temple is in a remote location, so that's all. ”

Li Muchen quickly found a reasonable explanation, every once in a while, sect elders would enter the crypt forbidden land to clean up, and this kind of treasure would naturally be collected, and the arrival of himself and the others was not in accordance with the opening law of the crypt forbidden land, and it was normal not to have much ancient demon essence blood.

Thinking about it in another way, if there is enough ancient demon essence blood, then the demonic qi that spreads out will be more, and the demonized demon beasts outside will be stronger, at that time, even the iron-crowned dragon eagle will have to be eroded by demonic qi. The sect is cleaned up every few decades, and there are also various considerations.

Li Muchen took out this piece of ancient demon blood jade and put it away, the red blood jade itself is also a treasure, combined with the ancient demon blood jade formed by the ancient demon essence blood, it can only be used with some secret methods, the effect mainly depends on the proportion of the two, this piece of ancient demon blood jade, because there is less silver blood in it, the quality is also relatively low.

Putting away the diamond-shaped jade, the central formation of the jade platform was activated, and Li Muchen was fixed to the edge of the main hall, as if to let him watch the production process of the ancient demon blood jade. A new jade emerged from the void, the jade fell into the card slot, a huge suction force was generated, the formation pattern continued to brighten, when it reached the extreme, a bloody light rushed out, and in the hole at the top of the hall, a strong aura was transmitted, and the boundless ferocity suddenly poured into Li Muchen's heart!

"Ancient Demon Essence Blood!"

Li Muchen's face was shocked, and he had an intuitive feeling of the strength of the Yuan Infant Cultivator, the ancient demon of the Yuan Infant Stage, the power contained in a drop of essence blood, was not something that Li Muchen could directly bear, if it weren't for the shield of the Candle Dragon Fire, Li Muchen would have been seriously injured under the impact of this breath!

This is still an ancient demon that has been sealed for thousands of years, and it is in a weak state!

The formation activated, suppressing the ancient demon essence blood seal towards the diamond-shaped blood jade, and at the same time, the demonic qi began to spread around.

A drop of ancient demon essence blood, after this purification, can only form a wisp of blood in the end.

"This, you can charge. ”

This trip to the Crypt Forbidden Land, the Xuantian Divine Strategy is quite active, needless to say, the previous giant spirit vein, this drop of essence blood, can also attract its attention?

"The silver-blooded demon clan has a unique spiritual talent, it is a common demon clan, and there are also top powerhouses, but I didn't expect that there is some bloodline here. The Ancient Demon Blood Jade Refining Method of the Changqing Sect only made use of a part of the power it contained, and the true essence was eliminated along with the demonic qi, of course, in their situation, this was also a reasonable way to use it. The forbidden secret method you practice can also be practiced with the help of it. ”

Xuantian Shence said indifferently, the demon race has been looting everywhere in the heavens and all the worlds, it can be said that it is pervasive, the aura of this world is not too thin, and it is normal for there to be the bloodline of high-level demons.

"How? Will it be noticed?"

Li Muchen's eyes lit up, and his first thought was what to do.

"It's okay, this formation is supposed to exclude the part you need, and the reason why those demon beasts have changed is because of this part of the power. Use the blood refining method to help this formation eliminate the impurities of the ancient demon essence blood, and collect it before it spreads out, as for this formation, according to Tiangang's footwork, three feet to the left, one zhang in front of it, it is in that position. ”

Xuantian Shence said, this thing is also an auxiliary cultivation method of the Naked Heart Secret Method.

"Good!"

Li Muchen did not hesitate and immediately acted according to the guidance of Xuantian Divine Strategy.

Tiangang footwork, Seven Star footwork, etc., all belong to the basic footwork, Li Muchen is very familiar with it, as for the blood refining method, he was already proficient when refining his own essence and blood before, and it quickly became effective.

With Li Muchen's help, the purification rate of the formation was much faster, and in less than an hour, this drop of ancient demon essence blood had already been integrated into the blood jade.

And in Li Muchen's hand, a drop of brown plasma condensed, and the anger was monstrous, and Li Muchen had to swallow a Tranquility Pill to protect his mind.

According to the explanation of the Xuantian Divine Strategy, except that because the demonic qi spreads less, the probability of demonization and mutation of the surrounding demon beasts is reduced, there will be no other abnormalities.

To Li Muchen's delight, just after refining this drop of ancient demon essence blood, the formation automatically operated, and another drop of ancient demon essence blood was extracted!

The source of the ancient demon essence blood is the same, and the difference in the quality of the ancient demon blood jade refined by each hall is related to the speed of their purification.

"That's it. ”

When the refining reached the fifth drop, the sense of crisis from the Qi Luck Secret Method emerged again, almost at the same time as the reminder of the Xuantian Divine Strategy.

A new drop of ancient demon spirit blood fell, and at the same time, a wave of fluctuations came from the center of the Crypt Forbidden Land!
