The Heavenly Ice Silkworm immediately popped up and explained:

"Ten years of soul beasts to be promoted to a hundred years is nothing, with enough soul power, ordinary beasts may also live to a hundred years, but a thousand years is a hurdle that is difficult to cross, it can be regarded as a small leap in the life level, where is it so easy to break through, especially the top soul beasts, the more powerful the bloodline, the more energy is needed when promoted, and it has to be high-quality energy ......"

Perhaps it was still under the deterrence of Ye Xi's spiritual power growth, but its tone this time was not too pretentious and arrogant, and it directly elaborated on the content.

"Uh......h To put it bluntly, you haven't eaten enough? ”

Ye Xi asked, and continued to nibble on the big pig's trotters with crispy skin and tough flesh.

"No, no, no!" Heavenly Dream Ice Silkworm hurriedly vetoed, "Who said that you can be directly promoted if you have enough energy, you have to be of high quality!" ”

"The quality of the energy rich in the flesh and blood of the thousand-year-old soul beast is not high enough? I feel that I am much stronger than a hundred-year-old soul beast, is it possible that I need a natural treasure? Ye Xi glared.

He couldn't help but think of those fire core grasses a few days ago, and the energy contained was indeed far purer than the flesh and blood of a thousand-year-old soul beast.

The Heavenly Dream Ice Silkworm said: "That's right, it just needs heavenly and earthly treasures, of course, it doesn't need to be as high-quality as the Fire Core Grass, just ordinary spiritual objects." ”

"Even if it's ordinary, I won't be able to find it for a while."

Ye Xi said helplessly.

The Heavenly Dream Ice Silkworm suddenly smiled slyly and said: "Don't worry, basically every soul beast that is more than a thousand years old will have heavenly and earthly treasures near its nest, some of which they have used when they have broken through a thousand years, some of them have occupied and guarded it in order to improve their cultivation, and some of them are even preparing in advance for breaking through ten thousand years."

Most of the limestone boars and other thousand-year-old soul beasts in the volcanic landform area have been cultivated, and even if they don't, you can choose to devour non-carnivorous plant-type soul beasts to accumulate high-quality energy, after all, they are the purest soul power among soul beasts. ”

Plant-based soul beasts have purer soul power, which is not what Ye Xi expected, after all, most of them are producers in the soul beast food chain, unlike top consumers like themselves, the content of heavy metals and other harmful substances in the body may have exploded......

However, what Ye Xi cared more about was not this, but the habit of cultivating heavenly and earthly treasures for thousand-year-old soul beasts.

"What will be the treasure of heaven and earth that the limestone boar possesses?"

Ye Xi carried a pork leg that had not yet been eaten, and began to search in the territory of the gray rock boar with a heartbeat.

The lairs of soul beasts are generally hidden in very hidden areas, but finding it out is not too difficult for Ye Xi.

He has devoured all kinds of canine, cat, and pig soul beasts, and his sense of smell has reached a certain level!

"Woo Woo ......"

He leaned down and clung to the ground, his black bear nose slightly stirring, and soon searched for the smell of the gray boar in the air and on the ground.

This kind of soul beast has the habit of rubbing on the rough rocks along the way, so as to remove the weeds that grow between the crevices of the rock crust as much as possible, so it will leave extremely obvious marks, which also plays a great role in Ye Xi's search work.

However, after a while, Ye Xi successfully found the nest of the rock-shelled wild boar under a stone mountain.

It was a deep cavern with a stone wall that had been rubbed to a very smooth surface, and there were many gray stone chips scattered inside.

According to the Heavenly Dream Ice Silkworm, this should be the rock shell that the gray rock boar regularly sheds and fades during its growth, similar to the snake molt of a snake soul beast.

"These are good snacks."

Ye Xi's bear paw greedily brushed over these mineral-rich rock crusts, and he secretly said in his heart.

He didn't stop to try to taste a piece, but continued to crawl quickly deeper into the cavern.

After going deeper, two forks appeared in the cave, one large and one small.

Ye Xi subconsciously drilled into the fork hole that was wider and had more friction marks on the stone wall, but there was not much value in this fork hole, just more piles of rock shell fragments.

He hurriedly returned the way he came, trying to enter another fork of the hole.

In the deepest part of this forked tunnel, he finally found something strange!

There was a small puddle that was no more than a few feet long and wide, and a small amount of richly colored white liquid had accumulated in the puddle, emitting a glossy shimmer and strong soul power fluctuations.

Looking above the puddle, a thick stalactite could be seen hanging out of the cave dome, and the tip of the stalactite was glowing with a slight white glow, as if a new liquid was forming.

"Maybe it's where this liquid comes from."

Ye Xi guessed for a while, and then asked the Heavenly Dream Ice Silkworm expectantly, "This should be regarded as a treasure of heaven and earth, right?" ”

"Well, this is a relatively common heavenly and earthly treasure, called the earth spirit liquid, which generally exists in caves with special locations, and is condensed by the soul power that penetrates into the earth's leylines for many years, and the quality is limited, but it is better than being peaceful in the middle, and it can improve the soul power of any soul beast, but the effect on rock-attribute soul beasts is better.

This small beach, at least it took decades to gather, the energy absorption efficiency of the limestone boar is far less than yours, most of them want to accumulate more and then eat together to enhance the effect, but I didn't expect it to be cheaper for you, although it is not much, but it should be enough for you to be promoted for a thousand years. ”

The Heavenly Ice Silkworm introduced with confidence, obviously more than once.

Seeing that it was so determined, Ye Xi continued to look at the pool of unknown liquid for a while, then rolled his tongue and swallowed it all into his mouth.

Suck!

"Tut-tut......"

Ye Xi slammed his mouth, he didn't taste it at all, it felt like drinking water.

Without a single waste, he jumped up and swallowed the drop of earth spirit liquid that was about to form at the end of the stalactite.

This spiritual liquid was very easy to digest, and after waiting for a long time, Ye Xi noticed that streams of pure soul power began to spread rapidly from his abdomen towards his limbs, making him feel refreshed.

The purple intent in the light of his soul power became more and more conspicuous, close to flocculent, and his cultivation was also approaching infinitely towards a thousand years.

But it still failed to break through in one fell swoop!

"Still can't do it......" Ye Xi couldn't help frowning.

These soul powers are almost equivalent to the soul power he can absorb from the flesh and blood of a soul beast of about a thousand years, and under normal circumstances, it is enough to improve his cultivation for more than a hundred years, but it is still useless!

Looking at this scene, the Heavenly Dream Ice Silkworm was also quite surprised, and explained in a deep voice:

"It's not that it can't be, but it's not enough, your bloodline level is much stronger than I thought...... Originally, I thought that your bloodline might not be as good as that of King Kong Bear, but it was affected by the human soul and had a special absorption ability.

But now it seems that this is not only the case, the bloodline contained in your soul beast body itself is probably not much inferior to the Dark Gold Dreadclaw Bear Clan! ”
