Under normal circumstances, the spiritual power in the demon core would not have any problem in preserving it for decades or even hundreds of years, and it would be impossible to deplete it in such a short period of time. The only explanation is that the spiritual power in the demon core was forcibly drained.

Ling Yifeng looked at the sleeping Huo Aya, the temperature of its body was much higher than usual, and Ling Yifeng seemed to have sensed that there was already a faint fluctuation of spiritual power in its body.

Not only can it devour the berserk spiritual power in the demon core, but it can also be converted into its own use?

Ling Yifeng was speechless in surprise, what kind of weird ability is this, what kind of weird monster is this little thing?

This sleep, Huo Aya woke up after three days, only to see it frowning, arching its body, its expression seemed to be a little painful, Ling Yifeng just wanted to lean over to take a look, but suddenly found that a burst of spiritual power fluctuations erupted from its body. Its body seemed to light up with a light that slowly moved up its belly and then over its neck, and it tilted its head and opened its mouth to the top of the cave.

"Whew!"

The firelight illuminated the entire cavern, and a huge fireball erupted into the air from Aya Fire's mouth. Ling Yifeng looked at the blazing fireball that was several times larger than Huo Aya's body in a daze, he could feel the scorching temperature far away, and a cold sweat couldn't help but break out on his back. He looked up at the top of the cave, where the weeds and bugs clinging to the rocks had been removed, and the solid rock was covered with blackened marks!

Spit out this flame, Huo Aya seemed to become much more comfortable, and it jumped excitedly and ran to Ling Yifeng's side, circling around him a few times. Ling Yifeng didn't come back to his senses in the shock just now, the huge spiritual power fluctuation just now seemed to be close to the spiritual power of a Spirit Wheel Realm powerhouse.

Staring at Huo Aya and taking a closer look, Ling Yifeng found that the spiritual power fluctuations in this little guy's body were only about six or seven layers of spiritual power, and the fireball just now should be the energy of the demon core that it had not digested!

"Sss

This kind of shortcut, it is estimated that no one dares to imitate it!

"You...... Do you want a magic core?" Huo Aya was tugging at his trouser legs, looking at him with blank eyes, Ling Yifeng's face couldn't help but twitch slightly.

Is it going to eat the magic core as a bean? After entering the Demon Beast Forest for so long, it has only been able to hunt a dozen demon cores, and these are all to be used to hand in tasks in exchange for payment. For this little guy to consume as food, Ling Yifeng couldn't help but feel a little painful, this little ancestor eats the demon core as a snack, and he can't afford to raise it!

However, Ling Yifeng still took out a piece of magic core and handed it to Huo Aya, only to see it happily holding the magic core and jumping and jumping, Ling Yifeng couldn't help but smile slightly when he looked at its excited appearance.

If the demon core is gone, you can find it again, since giving it food can improve its spiritual power, so what's the harm in giving it all? It is so dependent on itself, then, it also has a lot of benefits for itself to become stronger, right?

Huo Aya didn't immediately devour this demon core, probably because it had just absorbed a demon core, Ling Yifeng let it run out of the cave by itself.

Almost every four or five days for the next four or five days, Huo Aya was going to devour a demon core, and after devouring it, the time of slumber became shorter and shorter. It didn't have any special requirements for the attribute of the demon core, no matter what kind of attribute it came, except for the fire attribute demon core that it devoured for the first time, its spiritual power didn't grow so fast after that, but the speed of its spiritual power growth was still enough to make Ling Yifeng feel surprised, and even a little faintly worried!

More than half a month passed in a flash, and Ling Yifeng finally felt the signs that he was about to break through the barrier.

Just over there, I gave Huo Aya a magic core to absorb spiritual power, and I have already begun to prepare to break through the late stage of the Spirit Wheel Realm.

After calming his mind, Ling Yifeng sat cross-legged on the ground, Ling Tianjue was running at full speed, the acupoints and pores all over his body involuntarily opened to the maximum, greedily absorbing the aura of heaven and earth around him.

The "Ling Tianjue" technique is really good, breaking through the barrier is like a matter of course, in just an hour or so, Ling Yifeng didn't have much effort to break through to the late stage of the Spirit Wheel Realm!

Opening his eyes, Ling Yifeng felt an extreme sense of comfort, it was a feeling of being filled with strength, he stretched his whole body, and the sound of bones popping all over his body "crackled".

Twisting his neck, Ling Yifeng turned his head to look at the fire in the corner, the demon core it was holding had been devoured, and now it was refining spiritual power much faster than before, and it should be able to wake up tomorrow.

After breaking through the late stage of the Spirit Wheel Realm, he can continue to go deep into the Demon Beast Forest tomorrow, the peripheral environment is no longer suitable for his cultivation, and in the future, he will have to hunt at least one first-order Demon Beast every day, not only to consolidate his own cultivation, but also to provide Huo Aya with the resources it needs!

He still doesn't have a clue about the task he took in the Mercenary Guild, I'm afraid there is no hope for the task of submitting the magic core, these magic cores are not enough for Huo Aya to eat, and the task of finding the "Ice Heart Tears", he hasn't seen what that thing looks like until now! No matter what, he has to continue to go deeper into the Warcraft Forest.

"Little guy, how far can you grow, I'm really looking forward to it!" Ling Yifeng was happy when he thought about it, being able to have a powerful monster as a pet was the envy of many people!

Ling Yifeng walked out of the cave, it was still early, and he had to make some preparations for his actions after tomorrow.

He walked to the lake, filled a few water bags with fresh water, and then went to a nearby tree to pick a lot of wild fruits. Because he didn't know how long it would take to find food and fresh water, he was prepared in advance, and even if he couldn't catch food for several days in a row, he would be able to replenish his hunger.

After all, in this forest, the first thing is to ensure survival.

Looking at the number of demon cores in the space ring, Ling Yifeng smiled bitterly and shook his head, the dozen or so demon cores that had been captured in the two months since entering the forest were now only five, and these demon cores could be exchanged for at least thousands of gold baht!

After preparing the food and fresh water, Ling Yifeng returned to the cave. Everything is ready, and as soon as Aya wakes up, she can go.

As soon as it was dawn the next day, Huo Aya Youyou opened his eyes, and Ling Yifeng noticed that the spiritual power in its body had increased a lot, and it was already equivalent to the eighth or ninth layer of human spiritual power. He couldn't help but think of Ling Yu and Ling Yuexin, it had taken them several years of hard work to cultivate to the eighth level of spiritual power, and this little thing had actually reached this level in a month by devouring the demon core, which made Ling Yifeng envious.
