"Bang!" Above the thick trunk of the tree, a gray shadow rolled in embarrassment, slamming into it, bringing a low muffled sound. In the sound, the ancient tree shook, the fallen leaves flew, and the rolling demon wolf finally stopped the force of being knocked away and stopped.

"Whew!" After seeing the demon wolf get up on the spot, he stared at the fierce beast pupils again, staring at Ye Yi tightly. This time, however, the demon wolf that got up didn't roar angrily like before, and then opened its bloody mouth and pounced on Ye Yi again.

Instead, he stopped under the ancient tree and howled in a low voice. In the howl, the demon wolf's cold hair stood upright, its limbs opened and closed, and in the bloody mouth, the panting continued, this ferocious and incomparable demon wolf actually consumed a lot of physical strength in the battle with Ye Yi, and even his own breath began to become languishing!

"Is this an overdraft of physical strength?" Ye Yi raised his gaze, looked at the demon wolf who opened his bloody mouth and gasped violently, and felt the breath of the demon wolf's body gradually declining, and couldn't help but whisper in surprise. He didn't expect that with the depletion of the true qi in his dantian, this vicious demon wolf would also lose his physical strength at the same time.

"Oh, I forgot, I'm not the same now. Thinking about it, Ye Yi couldn't help but shake his head. He had forgotten that the exercises he was practicing now had already been promoted to the eighth rank of the Yellow Rank, which was one level higher than the exercises that only had the inferior chapters of the seventh rank of the White Rank. The true qi that can be stored in the dantian has long been extraordinary, and it is not at all that it will face the state of depletion of true qi after a few moves.

And with the true qi stored in his dantian, after such a long time of fighting, it was almost exhausted and almost exhausted, so the demon wolf who had been fighting with him for so long at the same time did not have physical strength and breath was not weak.

What's more, the strength of the demon wolf is still far behind him, although in the previous battle, he has tried his best to suppress the cultivation so that the demon wolf will not be injured and defeated under his fist, but with the strength of his strength at the peak of the ninth layer of qi refining, even if he only exerts seventy percent of his cultivation, it is equivalent to the entire strength of the demon wolf in the middle of the first order.

And under his previous exhaustive pursuit and fierce fighting, this demon wolf in the middle of the first order should now be seriously overdrawn, not to mention the palm he struck out at the end, but he hit eighty percent of his cultivation, this demon wolf with low strength, it is difficult not to weaken his breath!

"This won't work!" While thinking about it, he felt the fainter and weaker aura of the demon wolf, but Ye Yi's eyebrows slowly wrinkled. Right now, he has just swallowed the spirit grass, which is suitable for polishing the true qi through the assistance of the battle in a state where the true qi is depleted, so that he can achieve twice the result with half the effort.

And now that the demon wolf's physical strength is overdrawn and he can't fight, how can he use the assistance of battle to polish his true qi?

Looking down at the Qi Returning Pill under his feet, Ye Yi's brows were wrinkled deeper and deeper. When the monk's true qi is exhausted, he can also use the medicinal power of the elixir to restore his true qi, but the demon wolf's physical strength is overdrawn, how do he need to recover?

It would be nice if the demon beast could also absorb the medicinal power of the elixir and thus recover his strength, he didn't mind taking out the Qi Rejuvenation Pill he had to help the demon wolf recover his strength, so that he could quickly start polishing his true qi in the middle of the battle.

Anyway, now he, after the Beidou Five Spirit Sutra Derivation Spiritual Root, has long been extraordinary, and has the talent to absorb the energy of the Wind Spirit Grass and turn it into True Qi. In this crisis-ridden Meteorite Valley, it was not very important for him to give up some Qi Returning Pills that could restore his true qi.

"By the way, the true qi transformation, why didn't I think of it. Between thoughts, he felt the medicinal power that was constantly emanating from his abdomen, and thought of his talent for absorbing the energy of the wind attribute spirit grass, and in Ye Yi's mind, a flash of inspiration flashed!

After finishing speaking, Ye Yi actually stretched out his hand to the storage bag on his waist again, and then took out a carved flower and bird, quite luxurious brocade box from the storage bag. The brocade box opened, revealing a demon core as gentle as jade, and a jade bottle as white as mutton fat.

The contents of this brocade box turned out to be the essence blood and demon core that Ye Yi had entrusted Zhou Tao to help him extract from the corpse of the third-order demon beast Xuanfeng Wolf.

"Woo, woo......!" At the moment when Ye Yi opened the brocade box, and the gentle demon core was exposed to the air, the demon wolf with its limbs open and closed, and gasping for breath, as if it had noticed something, actually stared at Ye Yi and roared violently, and his eyes gradually became scarlet!

"Animals are worthy of being animals, and I noticed it so quickly, if it weren't for my lack of strength and weak breath, I am afraid that I would have pounced on me a long time ago. The change in the demon wolf was instantly noticed by Ye Yi. Raising his eyes, looking at the scarlet in the pupils of the demon wolf beast, and feeling the increasingly violent fury of the demon wolf, Ye Yi couldn't help but bend his mouth and whisper.

"Well, I'll be cheaper for you today. Seeing the demon wolf's more and more violent roar, Ye Yi couldn't help but be satisfied. When the words fell, Ye Yi directly opened the jade bottle, and then a drop of bright red essence blood dripped out of it, and with a flick of his fingers, the dripping demon beast essence blood flew towards the demon wolf who was physically exhausted.

Although the essence blood of the Xuanfeng Wolf in his hand was very rare and extremely precious, and it was a rare auxiliary for Qi Refining Cultivators to improve their cultivation, but now he already had Wind Spirit Grass to assist in his cultivation. The essence blood of this third-order demon beast is no longer important to him, so what does it matter if he feeds it to the demon wolf?

"Whew!" I saw that as soon as the demon beast essence blood popped out, there was a sound of wind, and the exhausted demon wolf with a weak breath actually jumped up in the air, and then swallowed the demon beast essence blood that bounced into the bloody mouth!

"It's kind of interesting. Looking at the movement of the demon wolf leaping up, after Ye Yi put away the brocade box, he said lightly. It seems that the essence blood of the Xuanfeng wolf is really not ordinarily attractive to the first-order demon wolf, and it is also that the demon core and essence blood of the high-level demon beasts among the demon beasts often have an extraordinary attraction to the low-level demon beasts.

As for the essence blood of the same kind of high-level demon wolf, the attraction of low-level demon wolves is even more fatal, and low-level demon wolves can undergo earth-shaking changes when they get a drop of high-level demon wolf's essence blood. Although the third-order demon beast Xuanfeng Wolf is not a high-level demon beast, it is already extraordinary for a first-order demon wolf, not to mention that its essence and blood itself is among the third-order demon beasts, and it is a special great supplement!

Since the demon wolf is devouring essence blood at this moment, it is presumable that its physical strength will soon recover, then his plan to polish his true qi in the middle of the battle should also be carried out! Thinking of this, Ye Yi wanted to raise his true qi, and after the demon wolf's aura recovered, he pounced again.

"That's not right!" Just when he mentioned his true qi, Ye Yi seemed to have discovered something, so he stopped what he was doing, and after condensing his gaze, Ye Yi once again looked at the demon wolf that refined essence blood, and carefully probed.

"Whew!" It's just that Ye Yi hasn't explored for long, and the demon wolf who refining essence blood actually looked up to the sky and roared. In the roar, I saw that the black mane between the neck of the demon wolf became more and more pitch black, and as for the previous sluggish aura, it quickly recovered, and soon returned to the state before the battle.

But this is not over, I saw that after the demon wolf's breath was restored, it did not end, but continued to climb. Soon, the aura of this demon wolf climbed to more than twice the level before, and then slowly stopped. This demon wolf in the middle of the first order, after refining the essence blood of the demon beast, actually advanced to the point of the late stage of the first order!

"Roar!" After the demon wolf finished his promotion, he glared at the fierce beast pupils again, and locked on to Ye Yi tightly. Unlike before, in the terrifying beast eyes of the demon wolf, a greedy gaze could even be vaguely seen. Immediately after, this vicious demon wolf finally opened its bloody mouth again and pounced straight at Ye Yi.

"Interesting!" seemed to feel the change in the demon wolf's gaze, Ye Yi was not angry but happy, but chuckled. As soon as the words fell, Ye Yi rushed out against the demon wolf that was attacking. After the training he had just fought for, now he was no longer afraid of the demon wolf's swift attack!

Now that the strength of the demon wolf has improved, it is more suitable for him to go through fighting, and through the assistance of battle, polish his true qi!

The only thing that puzzled me was that this mere mid-first-order demon wolf was able to advance to the late first-order level with a drop of Xuanfeng wolf's essence blood, which was really incredible. Although he was puzzled, this was no longer the focus of Ye Yi's thinking.

At this moment, with the pace of stepping, Ye Yi had already fought with the demon wolf who pounced on him, and fought with all his might!

During the battle, Ye Yi's cultivation was already running wildly. While refining the medicinal power from the devoured spirit grass, he directly guided out the true qi that had just been transformed, and slowly polished the true qi against the demon wolf.

True Qi polishing is divided into two parts, one is purification, and the other is condensation. Because only pure true qi has the possibility of condensing, otherwise, the true qi is not pure, and it cannot be condensed at all.

It is precisely for this reason that monks tend to retreat for a period of time before polishing their true qi with the help of battle, so as to spend a lot of energy to continuously refine and refine the true qi within their dantian. After his state reaches the peak, he will seek the assistance of battle, so as to condense his true qi.

As for ignoring the depletion of true qi and directly refining true qi through the assistance of battle, that is the patent of condensation stage cultivators! After advancing to the condensation stage, qi refining cultivators have already gone through the stage of condensation qi purification, and their own true qi has begun to transform into more powerful true yuan, which makes condensation stage cultivators more suitable for cultivation. Not only is it easier to refine and refine the aura absorbed in the future, but if you practice the Orange Rank Exercises, you can easily refine and refine the absorbed medicinal power from the elixir!

This made it possible for the Condensation Cultivator, when the True Qi was depleted, to polish the True Qi with the assistance of battle.
