When Han Feiyu stabilized his mind, he immediately followed in the direction the giant wolf had left. Han Feiyu was not afraid of going in the wrong direction, because in front of him, the constantly resounding wolf howls and tiger howls were his best signposts.

The spiritual power consumed is replenished by the spirit stones, as a cultivator, Han Feiyu is not afraid of exhaustion at this time, as long as he holds the spirit stone in his hand and is not in a situation where he is unable to make ends meet, he will not feel tired, which is also where cultivators are different from ordinary people.

Han Feiyu's speed is not slow, listening to the wolf howl and tiger roar in front of him, he secretly calculates his own process, he can't be greedy for merit, but he can't go too late, the snipe and the clam fight, and the fisherman profits, this is not wrong, but he must also find the right time. The giant wolf is obviously a much more powerful demon beast than him, and the tiger he hasn't met yet is not weaker than he thinks, and these two will make a move, and he will inevitably be affected if he goes early.

While hurrying, Han Feiyu paid attention to the howls of the two demon beasts, and when he felt that the cries of the two demon beasts were getting weaker and weaker, he sped up some speed and rushed towards the battlefield of the two demon beasts.

When he walked for almost a few miles, Han Feiyu found the corpse of a little wolf, it was a little wolf cub that was only less than twenty centimeters, thinking that it should be the child of the silver-gray giant wolf before, the neck of the little wolf had been bitten off, and at this time there were only some tendons connected, and the head would not fall off from the body, but it was already too dead to die anymore.

"It's quite a cute little guy!" Han Feiyu kicked the little wolf's body, the fluffy little guy naturally didn't look as fierce as the silver-gray giant wolf, just like the puppy in Han Feiyu's memory, quite cute.

"Little guy, next time you are reincarnated as a puppy, it is better than being a wolf to be held in your arms and raised!" Sighing softly, Han Feiyu no longer cared about the little wolf, and followed the sound in front of him, he sneaked forward again. At this moment, Han Feiyu had already felt that the wolf and tiger in the battle ahead had almost lost both, but it was time for him to come out and clean up the mess.

Sneaking all the way, Han Feiyu's face was somewhat solemn, and a little lucky, at this time, he knew how lucky he was before, the silver-gray giant wolf had not used its real strength at all before, thinking that it should have not been born for a long time, and he didn't want to make a big move, otherwise, even if the giant wolf had just given birth to cubs, it was definitely not something he could deal with.

On the battle route of one wolf and one tiger, many small trees with the thickness of the bowl mouth were broken by them, and on the ground, there were deep ravines from time to time, all of which were made with claws, and some tree trunks that were more than one person thick also had deep claw marks, Han Feiyu believed that the attacks that caused these marks, any one greeting on his body, was enough for him to drink a pot.

After walking for almost a few hundred meters, Han Feiyu finally stopped, and in front of his eyes, it was just the scene he hoped to see.

A silver-gray giant wolf was biting with a white tiger at this time, and the giant wolf was naturally the one that chased him before, but he had never seen a white tiger. At this moment, the two demon beasts were covered in blood, the giant wolf bit the neck of the white tiger, and one of the front paws of the white tiger was inserted into the belly of the giant wolf.

"Ha, a beast is a beast, even if it's a demon beast, but it can't be human's wisdom, why are you working so hard? If you have a grudge, can't you wait until you recover your vitality to report it?" Seeing that the two demon beasts had lost their combat effectiveness, Han Feiyu naturally walked in front of the two big guys and said to himself. He said that it was naturally a giant wolf, and it could be seen that the strength of the giant wolf was not weak, but it was a pity that it did not give birth for a long time, and it hurt its vitality greatly, so it would die with the white tiger.

Of course, then again, although the wisdom of demon beasts is a little worse, some of their nature is not worse than that of humans, for example, the giant wolf avenges his own child, undoubtedly ignoring his own weakness, which also makes Han Feiyu secretly moved.

"According to the jade jians I saw before, some demon beasts that can cultivate, it is also because they have something similar to a spiritual root, which can sense the aura of heaven and earth, and slowly cultivate, this giant wolf obviously has the strength of more than four levels of qi training, I believe it should be a demon beast Undoubtedly, I just don't know, does it have a spiritual root in its body?"

Han Feiyu didn't find this place to see the excitement, he ventured over this time, naturally he had his thoughts.

Devouring the spiritual root is known as the ultimate spiritual root, naturally it can only devour the spiritual root of people, as long as it is the spiritual root, even if it is the spiritual root of the demon beast, it can theoretically be devoured, the name of the ultimate spiritual root, that is not called in vain, Han Feiyu came with this time, just to try, whether his devouring spiritual root is spiritual or not, if it is really easy to use, then naturally he can find out the spiritual root of the giant wolf and devour it, and if he can devour the spiritual root of the giant wolf, then his spiritual root is bound to be able to be strengthened, and he can also have a greater grasp when he cultivates to the triple level of qi training。

After circling the two entangled demon beasts twice, Han Feiyu resolutely squatted next to the giant wolf after a little hesitation, and after making sure that the giant wolf at this time had completely lost its combat effectiveness, he finally slowly reached out and covered the giant wolf's back.

Spiritual roots are generally attached to the spine, and they are a kind of vein that runs through the upper and lower parts of the body, and this is true for humans, and the same should be true for demon beasts. Han Feiyu put his hand on the giant wolf's back, and then, he slowly closed his eyes, completely entering a mysterious state. In his mind, he saw a bright line in the middle of his back, which he had already felt when he was cultivating before, and it was his own spiritual root.

After sorting out his spiritual root, Han Feiyu sank his mind into the giant wolf's body again, and suddenly, a silver bright line appeared in his consciousness, it was the spiritual root of the giant wolf, and in comparison, the spiritual root of the giant wolf was more than twice as strong as his.

"Good guy, it's strange that I have to be this guy's opponent, look at this spiritual root, I'm afraid that he already has a five-fold cultivation of qi, I'm a little hairy boy with two levels of qi, it's weird to beat it!" After seeing the giant wolf's spiritual root clearly, Han Feiyu couldn't help but sigh with emotion. The spiritual root is growing with the improvement of cultivation, in order to meet the needs of new cultivation, like Han Feiyu's spiritual root at this time, it is much stronger than before opening up the sea of qi. Looking at the thickness of the giant wolf's spiritual root, it definitely has the grade of five levels of qi training.

Speaking of which, how the spiritual root grows, no one really can tell, but after the cultivation is promoted to a higher level, it will automatically be upgraded by one level, just like the feedback effect of the cultivation promotion. Moreover, only after cultivating to a higher level, the spiritual root can grow stronger, and the rest, no matter what method you want to use, it is impossible to make the spiritual root grow.

"Whew, devouring the spiritual root! Is it really easy to use, you will be able to see it immediately, my golden finger, you must not let me down! Devour the spiritual root, devour!"

Exhaling lightly, Han Feiyu stabilized his mind, and after praying in his heart, he immediately moved his heart, and his spiritual root immediately branched out into a branch vein, and pierced into the back of the giant wolf along his arm, and the spiritual root branch did not need him to control too much at all, so he found the silver spiritual root vein of the giant wolf, and then, Han Feiyu felt that the silver spiritual root vein of the giant wolf was being introduced into his spiritual root from his arm slightly, and the devouring of the spiritual root, which had almost never appeared against the sky, was staged for the first time in this heaven and earth。

"It's done, I can really devour it, I can really devour other people's spiritual roots to strengthen myself!" Feeling that the spiritual root of the giant wolf was swallowed into his own spiritual root little by little, and his spiritual root slowly became thicker, Han Feiyu was so excited that he almost screamed, this is not as simple as simply absorbing some energy, the devouring of the spiritual root is equivalent to the relationship between a fish and a fishing net, devouring some energy can only be regarded as getting a fish, while devouring other people's spiritual roots is equivalent to getting a fishing net, and the gap between this can be imagined.

Han Feiyu tried his best to control his mind and not let himself get too excited, for now, he still had to absorb all the spirit roots of the giant wolf first, this opportunity to strengthen the spirit roots, with his current cultivation, was really a once-in-a-lifetime opportunity.

Concentrating and calming down, Han Feiyu felt that his devouring was becoming more and more proficient, and his speed was naturally getting faster and faster, just because the giant wolf's spiritual root was stronger than him, his speed was a little slower, if the other party's spiritual root was weaker than him, he might be able to devour it at once.

The first time he devoured other people's spiritual roots, it was still a spiritual root three levels higher than his own, Han Feiyu took about five minutes, when he devoured all the spiritual roots of the giant wolf, he could feel that his spiritual roots were definitely thicker than before, but they suddenly reached the point of three levels of qi training, or even four levels of qi training, and he didn't know how much stronger than before.

I want to explain one point here, Han Feiyu devoured other people's spiritual roots, but it was impossible to turn all the other party's spiritual roots into his own spiritual roots, after some processing and refining, the utilization rate of the spiritual roots he devoured was about three or four percent, if it was good, it was almost fifty percent, but this is also understandable, after all, if he casually devoured a person's spiritual roots, he could attribute all the other party's spiritual roots to his own use, it would be really too rebellious. Of course, even if it is a utilization rate of three or four percent, it is actually very unnatural.

"Comfortable, the growth of the spiritual root is even more comfortable than the improvement of cultivation, it gives me the feeling that the whole person has become more transparent, and the sense of the aura between heaven and earth, I don't know how much clearer!" Standing up, Han Feiyu took a sharp breath, and suddenly, he felt that a large amount of spiritual energy poured into his spiritual root from heaven and earth, and then through the operation of the exercises, it was injected into the sea of qi, just this time, he was equivalent to devouring the spiritual energy of an hour before.

"Haha, the dual cultivation of qi can swallow spiritual qi like this, it is almost comparable to cultivating with spirit stones before, it seems that as long as I continue to grow the spiritual root, I don't know how much faster my cultivation in the future will be much faster than that of people of the same level!" Han Feiyu's joy at the moment no one can understand, with such a cheating machine, he knows what a rebellious existence he is. Thinking about it now, if Han Tian is not to be smuggled down from the immortal realm, how can an existence like him be able to accommodate him in a place like the immortal realm?

"Damn, what are you going to do here! There's still a big tiger waiting here, if you don't do anything, when this guy is completely dead, the spiritual root will disappear and be wasted. In addition to the excitement, Han Feiyu remembered that the spiritual root would slowly dissipate when the life died, and the white tiger at this time still had a breath, and when it really hung up, this spiritual root would be wasted.

Thinking of this, Han Feiyu no longer hesitated, and squatted down again, but he began to devour the spirit root of the white tiger.
