Although Xiao Bai is a skeleton, its various actions, coupled with the fact that it only appeared after Duan Fei's summoning, all indicate that it should be classified as a living thing.

If the World Tree can only accept energy with the same nature as "vitality", then in the Barren Bone Realm, it can only use Xiaobai's brains.

If the growth of the World Tree has in turn affected Xiaobai's growth, it is difficult to say whether this is putting the cart before the horse.

Right now, since Duan Fei knew that there was such a thing, he would definitely have to think of a way to solve it.

Xiaobai was troubled by this because it was in the Wild Bone Realm, and it couldn't find the power that could replace it, so naturally it couldn't make more attempts.

But Duan Fei would not have such a restriction, he could completely help Xiaobai think of more ways.

For example, right now, Duan Fei, who had already controlled the Heaven and Earth Valley, quickly thought of the many spiritual objects in the Heaven and Earth Valley!

The operating rules of the bloodline secret realm are to evolve from spiritual objects to heaven and earth spiritual objects, thus forming a cycle of spiritual power, so spiritual objects can also be regarded as a kind of power representing vitality.

Whether the World Tree needs to absorb vitality to grow, you can know if you use spiritual objects to do an experiment.

Duan Fei didn't covet the power of faith in the Heaven and Earth Valley, but he didn't need to be embarrassed to borrow a few spiritual objects for use.

The spiritual objects in the Heaven and Earth Valley are strange and strange, and there are all kinds of forms, but whether they are plant-based spiritual objects or animal-based spiritual objects, they are actually not suitable for appearing in the Barren Bone Realm.

Fortunately, there is another kind of spiritual creature in the Valley of Heaven and Earth that is extremely special, and it may be possible to describe them as non-living spiritual creatures.

This kind of non-living spiritual object may be a boulder, or it may be a spiritual spring, but it can also be regarded as a kind of spiritual object.

To put it bluntly, the existence of the bloodline secret realm is to use the spirit objects of heaven and earth to collect the power of faith, so it does not matter what form the spirit object is, the important thing is to be able to make living beings believe in it.

There are so many spiritual objects in the Heaven and Earth Valley, but there are always a few who can become Heaven and Earth Spirit Things, and it is even rarer for non-living Spirit Objects like this to become Heaven and Earth Spirit Things.

However, this kind of non-living spirit creature is very suitable for the Desolate Bone Realm, and it can be used to test whether the power absorbed by the World Tree can find a replacement.

With Duan Fei's status in Heaven and Earth Valley, as long as he made a decision, was there anything he couldn't do?

It was only a moment later that Duan Fei returned to the White Bone Hall with a glance at the spring.

This spring water was only the size of a zhang more than a square eye, and after being wrapped in Duan Fei's spiritual power, it was like a huge water ball.

However, this spring water is definitely a spiritual thing, even if it is wrapped in Duan Fei's spiritual power, you can feel that there is a spiritual power that keeps pouring with the fluctuations of the spring water.

It is obviously the most appropriate to choose a spring water spirit object for experimentation, even if the World Tree does not absorb vitality, but using spring water to water it will obviously make people feel the most comfortable.

At this time, the ground of the White Bone Hall was still cracked, so Duan Fei poured the spring water spirit object into it without hesitation.

Beneath the crack was a pitch-black void, and the spring spirit object disappeared directly after pouring it in, as if it didn't exist at all.

However, it was only after a moment that Xiaobai suddenly spoke: "It's useful." ”

Xiaobai has always been concise and to the point, and when he said the word "useful", it showed that the experiment of replacing it with spiritual objects was really successful.

The spring water spirit object has been integrated into the void under the Great Hall of the White Bone, and it doesn't matter what kind of way it exists now, the important thing is that the World Tree can absorb energy and continue to grow.

It didn't matter how long the spring water spirit creature could last, as long as it could make Xiao Bai breathe a sigh of relief, then it wouldn't have any problems advancing to the middle stage of the Soul Cultivation Realm.

Duan Fei also breathed a sigh of relief at this time, but still reminded: "This World Tree is very weird, but I don't need to sacrifice you to complete this thing." If this thing gets you in trouble again, don't forget to contact me.

A person who ponders and meditates will inevitably have shortcomings, and with my help, I can always help you save some effort. ”

Xiao Bai was noncommittal about Duan Fei's statement, but after solving the troubles caused by the World Tree, its attention finally fell on the reincarnated golden body of the Buddha and the big red robe brought by Duan Fei.

Although the big red robe was a treasure, it was of little use to Xiaobai, and it didn't care much after it glanced at it.

But the reincarnation of the Buddha's golden body was enough for Xiaobai to stay on it for a long time.

Even in the Wild Bone Realm, there are countless white bones piled up, but in terms of the quality of these white bones, how can they be compared to the reincarnated golden body of the Buddha?

The elite army under Xiaobai's command has improved their strength by replacing various parts of the body with better quality white bones.

If the reincarnated golden body of the Buddha is dismantled and the bones of the golden body are applied to the bodies of those elite skeletons, it will greatly improve their strength?

Of course, the reincarnation of the Buddha's golden body is a very sacred relic for Buddhism, and if it is disassembled and assembled on different skeletons, it is definitely a great disrespect to Buddhism.

But for Xiaobai, it doesn't have any special feelings for Buddhism, if the reincarnation of the Buddha's golden body is helpful to improve the strength of the skeleton army, then Xiaobai will not hesitate to dismantle the golden body.

In fact, Xiao Bai didn't say politely, it said directly to Duan Fei: "This golden skeleton stays, it's useful." ”

Since Xiao Bai spoke, Duan Fei naturally would not refuse, but he still reminded Xiao Bai.

"This golden body should be related to the Upper World, and it is very important, and it may be more useful to be able to keep it intact. ”

But Xiaobai still looked noncommittal, and said directly: "Useful is useful, I have my own arrangements." ”

In this way, Duan Fei didn't say anything more, but nodded to Xiao Bai, indicating that everything would be as it wished.

Although Zhu Wushuang and Daozi of the Northern Xuanyu Domain had already retreated in defeat, Duan Fei was not suitable for staying in the Desolate Bone Realm for too long at this time, because the next Heaven and Earth Valley would definitely be extremely lively.

Sending the reincarnated golden body of the Buddha and the big red robe into the Barren Bone Realm was to avoid trouble for Duan Fei, and now the affairs of the Barren Bone Realm were handed over to Xiaobai to deal with, and Duan Fei retreated to the Heaven and Earth Valley.

In the Heaven and Earth Valley, the five major order guardian spirits were waiting for them, and the five-pointed starfish demon beasts were still suppressed by them, which was the price that had to be paid for invading the Heaven and Earth Valley.

However, the next development, relying only on the five guardian spirits of the order, may not be able to hold up the scene.
