Xiao Yu looked inwardly at his 'Foundation Building Essence' and couldn't help frowning.

In his sea of qi, a mass of black and gold liquid that could not change was suspended in the middle, slowly turning.

Around this mass of liquid, there are clusters of heaven and earth vitality that seem to be rolled by clouds, and this scene is like a star map in the sky, which is quite spectacular.

The senior brother of the White Bone Gate who was killed in the cave was about to build the foundation, so he stored a lot of books about the foundation building in his storage bag.

The reason why Xiao Yu frowned was because it was mentioned in these books that if a cultivator who cultivated a decent ** cultivator succeeded in building a foundation, the 'foundation building essence' should be gold, while a cultivator of the evil sect succeeded in building a foundation, the 'foundation building essence' should be black.

His own 'Foundation Building True Essence' is the evil sect' 'Foundation Building True Essence' that the spirit of the evil god seed snatched from the ghost tears of the White Bone Gate, and its color is originally black, if you have enough divine sense, you can turn all these black 'Foundation Building True Essence' into gold in the process of fusion.

It's a pity that only half of the 'Foundation Building True Essence' of his golden divine consciousness can be fused, and the remaining half is fused by the spirit of the evil god and spirit species, and from the perspective of color, the spirit of the evil god spirit seed obviously belongs to the evil sect.

After the second fusion of these two colors of the 'Tsukiji Essence', he himself couldn't figure out whether the 'Tsukiji Essence' that couldn't change in black and gold should belong to the righteous or evil sect.

"Hey, you're not afraid of shadow evil, as long as you act right and do it properly, it doesn't matter if it's decent or evil!"

Xiao Yu left behind his somewhat troubled thoughts, tried to operate the 'Foundation Building True Essence' in the sea of qi, and absorbed the Heaven and Earth Yuan Qi.

I only felt a burst of coolness at the 'Baihui Acupoint' above my head, and the bubbling heaven and earth vitality poured into my body like a thin white line, converging into the sea of qi.

Xiao Yu was overjoyed in his heart, compared to the speed at which an old lady was dripping urine before, the speed of absorbing the vitality of heaven and earth was obviously ten times faster. If, with the assistance of 'Gathering Strength', the absorption rate can be much faster.

It seems that there is a world of difference between this foundation building period and the qi condensation period, no wonder countless cultivators have gone to great lengths to advance to build a foundation, just from the absorption of heaven and earth vitality, there are definitely too many cultivators beyond the qi condensation period.

According to the excitement of patience, Xiao Yu suddenly remembered something in his heart, when he used the 'Eagle Eye' skill, he found that the original place that needed to use internal force had been replaced by the Heaven and Earth Yuan Qi, since the 'Eagle Eye' skill was like this, would other skills also change accordingly?

What Xiao Yu is worried about is that maybe things are not all developing on the good side, if a certain skill cannot be used because of the disappearance of his internal force, wouldn't it be a big loss.

Xiao Yu's first skill to check, is the 'Holy Shield', also known as the 'Invincible Golden Body', this is his first life-saving skill, in many battles, he saved Xiao Yu's life when he was critical, if this skill cannot be used, then in the future battle, he will be extremely difficult.

'Holy Shield - Can envelop itself in an impenetrable barrier of light, protecting it from physical and magical damage. Rank intermediate, with a maximum duration of 10 seconds, costing 100 points of Heaven and Earth Yuan Qi per second. Xiao Yu let out a sigh, 100 points of Heaven and Earth Yuan Qi replaced the original 100 points of internal force, although the effect of the 'Divine Shield' has not been strengthened in the slightest, but as long as this skill can still be used, it is already thankful.

This skill is really against the sky, and the 100 points of heaven and earth vitality consumed per second really hurt Xiao Yu.

I looked at the other skills again.

After a while, Xiao Yu's heart was put down.

Those skills that originally required internal force have now been replaced by the Heaven and Earth Yuan Qi, and as for its effect, it doesn't seem to be as significant as the 'Eagle Eye' skill, and the specific effect can only be discovered in the process of battle.

Looking at so many skills that needed the support of Heaven and Earth Yuan Qi, Xiao Yu couldn't help but smile bitterly, after the foundation was successfully built, although the absorption of Heaven and Earth Yuan Qi increased greatly, the channels of consumption also increased correspondingly.

At present, it seems that the two skills that consume the most Heaven and Earth Yuan Qi are the 'Divine Shield' and the 'Identification Technique'.

Take the skill of 'Holy Shield' as an example, it takes 100 points of Heaven and Earth Yuan Qi to use it once, and if it lasts for ten seconds, the amount of Heaven and Earth Yuan Qi consumed is equivalent to the reserve of a low-grade spirit stone.

It's a burn of money! You must know that the price of a low-grade spirit stone is 1 million yuan!

And every time the 'Appraisal Technique' is identified, it needs to consume 100 points of Heaven and Earth Yuan Qi, and the Appraisal Technique also has a limit on the success rate, which does not guarantee the success of the appraisal.

Let Xiaoyu have to think twice when he uses the identification technique in the future.

Moreover, what gave him a headache was that so far, he did not have a set of cultivation ** suitable for his own cultivation.

Cultivation ** is extremely important to cultivators, and it can be said that they are partners who accompany cultivators for a lifetime. It can purify the Heaven and Earth Yuan Qi in the body, making it more suitable for cultivators.

If you use cooking as an analogy, the vitality of heaven and earth is like unprocessed ingredients, and Xiuzhen ** is the method of cooking, after cooking, the ingredients can become delicious dishes, although the ingredients themselves have not changed, but they are more suitable for people to enjoy.

A good set of cultivators** can not only give cultivators greater magical powers, but also much faster than cultivators who cultivate in general** in terms of cultivation speed.

Xiao Yu's current cultivation of the 'Heaven and Earth Decision' is actually a set of incomplete refining bodies**, which cannot purify the Heaven and Earth Yuan Qi in his body, so he must also find a set of spiritual cultivation that he can cultivate**.

Lao Li Tou once said that the spirit body cannot be dual-cultivated, otherwise the entry will be ten times slower than others, and in the end, the longevity will be exhausted and it will not be able to advance.

However, because of a coincidence, he has successfully built a foundation, so if he doesn't cultivate spiritual cultivation, wouldn't he be tyrannical?

At present, in addition to the set of 'White Bone Yin Decision' in his hand, it is the 'Black Magic Skill' found from Gongsun Gu, these two ** look left and right, they are a little ghostly, and they will never practice.

It seems that at next week's cultivation fair, I have another task, in addition to looking for the next part of the 'Heaven and Earth Decision', I also have to find a spiritual cultivation suitable for my own cultivation**.

Letting go of all these thoughts, Xiao Yu took out the storage bag he got from the old guy in the 'White Bone Gate' from the storage bag.

Looking at the green skull mark printed on the storage bag, Xiao Yu's heart moved, he reached out and looked at the palm of his right palm, and couldn't help but let out a soft 'huh' in his mouth, with a look of joy on his face, the pale green skull mark that had been entangled with him for several days disappeared at some point.

Thinking about it, it must have something to do with the fact that he fused the 'Foundation Building True Essence' of the old guy from the White Bone Gate, and it is possible that in the process of the 'Foundation Building True Essence' entering his body, he casually absorbed this mark of the same nature as it.

Finally able to get rid of the entanglement of the White Bone Gate, Xiao Yu's heart couldn't help but feel relieved, it was already very difficult for him to deal with the old guy in the foundation building period, if he met the Heavenly Demon Lord, he could press himself to death like an ant without much effort.

Looking at the old guy's storage bag in his hand, Xiao Yu's consciousness in the sea surged with filaments, and he went around the mouth of the storage bag and got in.

This storage bag is twice as big as the storage bag of the senior brother of the White Bone Gate, the old guy is a cultivator in the late stage of foundation building, and the collection is obviously much more than that of the senior brother of the White Bone Gate, just the spirit stones, Xiao Yu found more than 100 lower-grade spirit stones, and in a small box, he found five or six medium-grade spirit stones.

"Heaven and Earth Spirit Stone - Absorb the essence of the sun and the moon, naturally cultivated between heaven and earth, grade: medium grade, spiritual energy reserves: 10,000."

Xiao Yu couldn't help but secretly rejoice when he saw it, judging from the reserves of spiritual energy, the reserves of medium-grade spirit stones were ten times that of lower-grade spirit stones, it seemed that if the price was calculated in RMB, I am afraid it would be 10 million.

No wonder people say that cultivators regard money as dung, and taking out a spirit stone is enough to meet the needs of a mortal family for a lifetime.

However, this kind of treasure that can quickly restore the vitality of heaven and earth can save the life of a cultivator when it is critical, who would be willing to sell it for money?

The old guy's collection of books was also twice as large as that of the White Bone Sect Senior Brother, and the level of these books was obviously much higher than the one he had obtained before.

And the most in the storage bag is the talisman.

Xiao Yu suspected that this old guy had a habit of collecting runes, and the two bookshelves had runes of different forms, which made Xiao Yu's eyes dazzled.

Xiao Yu hadn't taken the time to study the usage of these White Bone Gate talismans, and saw that the people in the White Bone Gate, whether they were disciples in the Qi Condensation Period or in the Foundation Building Period, kept them as treasures, and they must have their special uses.

Xiao Yu's divine sense searched the storage space, he was not too interested in these books and talismans, but hoped to find one or two powerful magic weapons in the storage bag of this old guy in the late stage of foundation building, because his current attack was too weak.

You must know that only items above the Xuan level can be called magic weapons, and they can be driven by the Heaven and Earth Yuan Qi and change their size at will.

And in addition to the 'Mo Yu Xiao' in his hand, there are no other decent magic weapons, and the 'Mo Yu Xiao' is at best just a magic weapon that uses sound waves to assist attacks, and it cannot be called an offensive magic weapon in the true sense.

Xiao Yu searched for a long time, and couldn't help but be a little disappointed, in the old guy's storage bag, except for the 'white phosphorus bone shield' that he took from his hand, the other magic weapons were nothing, it seems that this old guy has only cultivated a natal magic weapon, which is the turquoise flag.

The small banner looks quite powerful, it should be a magic weapon above the Xuan level, but unfortunately, in order to save Zhu Jiajia's life, the small banner has been replaced by the little fairy and missed himself.

However, this kind of magic weapon that attacks the enemy with a large number of souls is obviously not something that you can use, to be honest, the soul in that small banner has long been sucked away by the spirit of the evil god and spirit seed, and it has become a useless ornament, if you want to use it again, you need to fill it with a large number of souls, where can you go to collect so many souls?

It seems that his attack power will not be improved in the short term, but fortunately, he has gained a large number of spirit stones this time, and he should be able to exchange for a good attacking magic weapon at the Xiuzhen Fellow Dao Trade Fair.

I don't know when, the weight of this fellow cultivator trade in Xiao Yu's heart has gradually become more and more important.
