Standing next to the Spirit Gathering Array, just like absorbing spiritual crystals, Li Guo held this newly appeared light green crystal in his right hand and activated the soul refining method in the 'Undead Soul', and immediately felt a trace of inexplicable energy being absorbed along his right palm. Pen? Interesting? Pavilion wWw. ｂiquge。 But Li Guo knew very well that this was not soul power at all.

Suddenly, Li Guo frowned slightly, and then his eyes turned red, and a miserable scream instantly sounded in Li Guo's mouth - my mana!

Li Guo hurriedly shook off the pale green crystal in his hand as if he was dodging the plague, because the energy absorbed in the green crystal not only did not increase Li Guo's soul power in the slightest, but decreased significantly, can this not make Li Guo startled?!

What the hell is this? It was also the energy crystallization gathered by the Spirit Gathering Circle, how could it have a completely opposite effect? Spiritual crystals will increase one's soul power, but the energy channeled from this strange pale green crystal seems to eat one's soul power, which is a kind of poison for a mage at all!

Muttered a few words in annoyance, after all, after waiting for nearly an hour, the result was that the soul power was weakened, isn't it okay for me to be idle? But while Li Guo was secretly angry, he suddenly found that a trace of a slightly different energy seemed to appear in his soul power. It's broken, is there any aftermath of this thing?!

Through the precise control of soul energy, Li Guo found that trace of soul power that changed, and carried out some experimental use of this trace of soul energy, and found that it was completely normal, and any magic could be used normally. Bone blade, bone spear technique, attack after controlling the eight realms of materialization, let him fly on his own, and let Xiao Shi fight after going crazy, all of which are not delayed!

Then he used the soul refining method to restore the soul power, and as a result, the soul power that disappeared was quickly cultivated back, and the recovery speed was still the same as before, and it was not affected by that trace of abnormal energy. There is no delay in using and cultivating, so it seems that although I was taken aback just now, there are no serious consequences, so it doesn't matter.

Well? Wrong! Li Guo, who had settled down, suddenly felt as if there was still something different from before! There's not much energy in this way, how did you do so much?! Although each magic plum fruit just now stopped after trying it, after all, there were several of them, and the consumption of mana after controlling the eight substantiation actions and making Xiao Shi go crazy was particularly powerful, but just a little bit of changed energy was all supported! Under normal circumstances, with such a small amount of soul power as a mana supply, it is estimated that using the bone blade twice would be about the same, how can it support this level of mana consumption?!

The same amount of soul power can do more than before, and this phenomenon seems to mean ...... This trace of soul power has been compressed and purified! Only in this case will the weight of power become less, but the things that can support Li Guo to do will not decrease. In this way, although this newly appeared light green crystal does not have soul power, it can purify soul power, and it is definitely a treasure that is not inferior to spirit crystals!

Imagine if Li Guo used this thing to purify all his soul power, wouldn't it be equivalent to Li Guo's cultivation being unchanged, but his mana would be able to supply him to do more things, what is the difference between this and the direct improvement of mana?

In that case, then what is there to hesitate about? That pale green crystal was directly absorbed by Li Guo in one go, and at the same time, Li Guo also felt that almost twice as much of his soul power had changed. After stabilizing, these soul powers will only be one-tenth of their original weight. It seems that a light green crystal can almost purify twice the soul power, and among the twenty-five times of one's soul power, the twenty times the soul power that can be used requires almost a day to condense the light green crystal to compress and purify.

Thinking of this, Li Guo was not in a hurry to continue to purify his soul power, and directly handed Xiao Bai a task, asking him to look at the Spirit Gathering Circle and collect light green crystals as soon as possible. As soon as a crystal is formed, Xiaobai will immediately retrieve it back to the attached undead space. Li Guo planned to wait for enough of this thing to purify all his soul power at once.

Li Guo named this pale green crystal that can purify soul power as 'green crystal', which is different from the 'white crystal' of spiritual crystal. Then he named the energy in the green crystal green energy, and he would often use this green energy to purify his soul power in the future.

However, there is another question, how did the formation of this green crystal happen, this has not happened in the previous Spirit Gathering Circle. The Spirit Gathering Circle itself was no different, it was still the magic circle that Li Guo had often arranged before. The only thing that is a little special is that this time the circle is set up in the undead space, not in the outside world. Could it be that because of this, the energy gathered by the Spirit Gathering Circle changed from soul power to this newly emerged energy?

This is possible, the environment of the undead space plane is completely different from the outside world, and it is reasonable that the energy collected here will change. However, this Spirit Gathering Circle should be specially used to collect soul power, for example, ordinary aura in the outside world cannot be gathered into crystals, and negative energy is not good, why can this non-soul power energy alone be gathered?

In fact, what Li Guo didn't know was that this kind of green energy and soul energy were originally of the same origin, and when green energy met ordinary soul energy, what happened was not the situation of who purified whom, which simply formed a new type of energy, or that this was just a restoration of the original form of energy.

It's a stunning discovery by a magical genius and a sinister conspiracy by those behind it. But Li Guo, who was in it, could only experience the benefits of this new energy now, and it was impossible for him to understand what was hidden behind it for the time being.

Li Guo didn't figure out where this green energy came from for a while, it must have something to do with something in this undead plane. But this is not very important, the important thing is that as long as Li Guo can collect green crystals here for his own use.

It wasn't until Li Guo collected enough green crystals, purified all his soul energy, and re-practiced his twenty-five times soul power before he was a little embarrassed to find that among his soul power, the amount of energy that was really purified was only twice the amount of soul power, and the rest was still normal.

This discovery made Li Guo a little troubled, originally thinking that as long as all the soul power was purified, his soul power would all become the purified state. Now it seems that his original twenty times soul power except for the soul origin has all become twice the soul power after the change, and the soul power that Li Guo has re-cultivated is still the same as before, it seems that this task of refining soul power is still quite a long way to go!
