readx;? Han Feiyu's whole person became very cautious, now it seems that the special gray qi of these suspected creatures, in addition to the true immortal law, seems to be able to use any energy as a ration to swallow, which can't help but surprise him, even the immortal yuan power can be eaten, and after eating it, it is obviously stronger, these gray microorganisms, if they don't say a little, it would be strange.

"What should I do? How else can I study these gray energies? Immortal Yuan Force has also swallowed, and other energies have also been tried, how can I study these things?" Han Feiyu frowned, but he didn't know how to find out how to use these gray energies. Faintly, he could feel that these energies were unusual, and he could even feel that these gray energies would definitely be useful to him.

"Creatures, energy, what are you going to do?" his eyes narrowed slightly, and Han Feiyu stared at the gray mist in front of him tightly, and he also fell into deep thought for a while. He needed to think about what he was going to do.

"Hmph, so far, I can only take a risk, whether these gray energies are creatures or ordinary energies, their existence forms are in a gaseous state, I can completely absorb these grays as ordinary energy gases, I have devouring spiritual roots, what kind of energy can't be absorbed? Besides, even if something happens, as long as I run the True Immortal Law, I can also neutralize these energies. ”

Finally, after thinking about it for a long time and not coming up with an excellent solution, Han Feiyu finally made a decision, that is, to test the method, absorb some gray gas into the body, and experiment with the effect with actual feelings.

In fact, from the very beginning, Han Feiyu knew in his heart that if he wanted to figure out the usefulness of these gray energies, he was afraid that he would have to pay some dangers in the end, but this gray gas could even be devoured by the Immortal Yuan Force, which made him a little hesitant for a while, not knowing if he should take this risk, but now, he knew that if he didn't take the risk, he would never be able to unlock the secrets of these gray energies.

Of course, although there are dangers, he has a large number of True Immortal Laws in his body, and he should be able to deal with the changes brought about by these gray energies. If you want to get benefits, you naturally have to pay some dangers.

"That's it, True Immortal Law, protect the whole body, gray energy, devour and absorb it for me!" As soon as he gritted his teeth, Han Feiyu also made up his mind, and with a movement of his mind, he suddenly pulled out a cloud of gray energy and absorbed it into his body.

So far, Han Feiyu has absorbed more energy, but like this time, absorbing these weird gray gases, he is undoubtedly the first time, speaking in his heart, he is still worried, after all, these energies can even neutralize the power of the True Immortal Law, but he is flesh and blood, God knows if he will be corroded by these gray energy gases.

To be on the safe side, Han Feiyu first wrapped these gray energies with the True Immortal Laws, and then slowly swallowed them into his spiritual roots, as soon as these energies came into contact with the True Immortal Laws, they canceled each other out with the True Immortal Laws, "Huh, can it help, let me wait and see!" True Immortal Laws, retreat!" At a certain moment, when the gray gas was almost neutralized with the power of the True Immortal Rule, and only the last trace remained, Han Feiyu's eyes lit up, and the True Immortal Law wrapped in the gray gas was suddenly put away, but it was the only trace of gray gas that was left to directly enter his spiritual root.

He has also calculated for a long time, and the last remaining trace of gray energy can just be used for research, if it is too little, I am afraid that it will not be able to study anything, if it is too much, it may be dangerous, but the amount at this time is just right.

"!!" After the power of the True Immortal Law was withdrawn, the gray energy gas directly entered the Devouring Spirit Root, and then, a scene that made Han Feiyu's pupils shrink happened.

With a snort, that trace of gray energy gas was suddenly absorbed by the Devouring Spirit Root, and the feeling was like Devouring the Spirit Root feeling delicious, just like a beggar who had been hungry for a few days, suddenly saw a roast chicken, and devoured it.

"This, my spiritual root actually took the initiative to absorb these energies?" Han Feiyu's expression was suddenly shocked, this was the first time he had seen the devouring spiritual root take the initiative to devour some energy, the devouring spiritual root had devoured a lot of energy, and even other people's spiritual roots had not been devoured, but every time he took the initiative to control and master it, so that he could devour, like this time, he took the initiative to devour energy, this was the first time in the world.

"It's going to take the initiative to devour, this ............" Han Feiyu's eyes changed, and then his face suddenly changed, "There is a change, there is a change, my devouring spirit root is changing!"

The gray gas had just been absorbed by the Devouring Spirit Root, and Han Feiyu felt the change, at this moment he found that his Devouring Spirit Root, especially the part that had absorbed the gray gas, suddenly had a strange feeling at this moment, and the originally golden Spirit Root actually had an extra touch of gray, a very weird gray.

"Buzzing !!" Suddenly, the entire towering giant tree transformed by the Devouring Spirit Root shook violently, and then, Han Feiyu was shocked to find that the trace of gray energy that had been integrated into the Devouring Spirit Root, like a long snake, began to swim quickly in the Devouring Spirit Root, and as this gray energy began to swim away, the entire Devouring Spirit Root began to vibrate.

"What's the situation? Can anyone tell me what the situation is?" Sensing the change, Han Feiyu's whole body became nervous, however, he didn't take any action, because although this gray energy was scurrying in the spirit root, he didn't feel any discomfort, and at this moment, it seemed that even if he wanted to reach in, it didn't seem to be so simple and easy.

The trace of gray energy of "sneering !!" wandered away, and soon disappeared, but it was slowly divided up by the huge devouring spirit root.

Han Feiyu concentrated, "My spiritual root, my spiritual root seems to have improved, this, it can't be an illusion, right?" After the gray energy disappeared, Han Feiyu hurriedly sank his mind into devouring the spiritual root, and at this look, he couldn't help but look abrupt. At this moment, he suddenly had a feeling that his devouring spirit root seemed to be stronger than before.

"Is it an illusion? It must be, although these gray gases are strange, how can they make the devouring spirit root pure?" Although he felt that his spirit root seemed to have improved, but unfortunately the effect was not obvious, and he was a little unsure.

"Whew, why don't you try absorbing some more?" Anyway, after these gray energies were added to the Devouring Spirit Root, they didn't bring him any bad effects, as long as there were no bad effects, then he would naturally be much more relieved. Let's not talk about whether it is good or not, at least there will be no harm, which can be regarded as a reassuring pill for him.

"Don't wait any longer and see if anything happens! To be on the safe side, Han Feiyu didn't rush to devour it again, but waited here to see if there would be any changes in his spiritual root.

This kind of waiting lasted for almost half a quarter of an hour, and in this half a quarter of an hour, his spiritual root did not feel anything abnormal, obviously the gray energy that was devoured before was not enough, whether it was a good effect or a bad effect, but it did not show it.

However, in this half an hour, Han Feiyu's True Immortal Law was not wasted, in order to resist the invasion of these gray energies, his True Immortal Law was consumed all the time, so far, the True Immortal Law consumed by him entering this place this time was probably comparable to all the True Immortal Law stock of a True Immortal Realm five or six great masters.

"Again, devour the spirit root, devour it directly!" At a certain moment, Han Feiyu gritted his teeth again, this time, he simply didn't wrap these gray gases with the True Immortal Rule, but directly devoured a cloud of gray energy with the Devouring Spirit Root.

"Puff !!" is the same as before, this time, a large cloud of gray energy entered the devouring spirit root, and it was also dissolved by the devouring spirit root in an instant, and the gray energy mass was directly integrated into the spirit root, and it turned into a gray trajectory again, and the energy was continuously integrated into the devouring spirit root, but this time there was a lot more gray gas, and it was not completely dissipated for half a day.

"Sneer!!" A trace of gray energy was added to the spiritual root, and this time, Han Feiyu's feelings were much deeper than before.

"Buzzing !!" The gray energy was absorbed by the devouring spirit root, Han Feiyu suddenly felt that his spirit root was obviously shaking this time, and he found that at this moment, his spirit root was slowly shrinking, yes, it was shrinking, although it was a slight shrinkage, but it was indeed small.

"It's smaller, my spiritual root has become smaller!" Han Feiyu couldn't help but exclaim in the bottom of his heart, but although he was surprised, he didn't have the slightest hint of worry, on the contrary, after feeling that his spiritual root had become smaller, he even had a faint surprise, "My spiritual root, my spiritual root is obviously more refined, those gray energy, devouring the impurities in my spiritual root, but it makes my spiritual root more refined and stronger!" Han Feiyu suddenly understood the effect of these gray energies, these gray special energies were actually able to help him refine his spiritual roots, at least now it seemed like this.

Although Han Feiyu's devouring spirit root is unparalleled in the world, this spirit root is not absolutely perfect, in the spirit root, there are still some impurities, these impurities will naturally affect the overall level of the devouring spirit root, and once the impurities are clear, then, even if his devouring spirit root is less in quantity, but in terms of quality, it will be improved to a higher level, and the final effect will naturally outweigh the disadvantages.

"Again, if you can refine my spiritual root, just swallow some more of these gases, and let me continue to devour. After having the effect, Han Feiyu naturally worked harder, and in an instant, he began to devour these gray gases again. v！！！
