Journey to the Star Dou Great Forest, Five-Thousand-Year Undying Grass!

"It seemed that using the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot still couldn't trigger another evolution in the Blue Silver Spirit Jade Vine."

"However, after the Ice Fire Body Tempering, the Blue Silver Spirit Jade Vine should now be immune to ice and fire energy attacks below the ultimate level!"

Looking at the Blue Silver Spirit Jade Vine emerging in his hand, its entire body crystal-clear like blue crystal, its stems and leaves filled with golden threads and entwined with crimson and icy-blue patterns, Ye Yu muttered to himself.

At this moment, he was the only one near the Ice and Fire Yin Yang Well.

When he had first begun the Ice Fire Body Tempering, Dugu Bo had been rather concerned and stayed behind to watch over him.

But later, after realizing nothing was wrong,

Dugu Bo only came by occasionally to cultivate in seclusion.

Most of the time, he remained at Dugu Manor, studying Whale Rubber.

Following Ye Yu's ideas, he planned to develop a body-strengthening potion with Whale Rubber as its primary ingredient.

Originally, after consuming the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot and undergoing the Ice Fire Body Tempering,

Ye Yu had intended to consume the Singular Velvet Sky Chrysanthemum and Narcissus Jade Marrow Bone as well, tempering his body once more.

Then, starting with his First Spirit Ring, he would absorb Thousand Year Spirit Rings!

But after completing the Ice Fire Body Tempering,

Ye Yu discovered that its effects were far stronger than he had imagined.

At that moment, Ye Yu remembered something.

Tang San's fourth Spirit Ring seemed to have been a Ten Thousand Year Spirit Ring.

And according to Yu Xiaogang's Spirit Ring Absorption Limit Theory,

even within Spirit Hall, the Soul Warrior with the highest age limit for a fourth Spirit Ring had only absorbed a five-thousand-year Spirit Ring.

This meant that the Ice Fire Body Tempering should be able to increase one's Spirit Ring absorption limit by around five thousand years!

Combined with the physical enhancement brought by fusing with the Blue Silver Emperor's Right Leg Bone,

as long as he consumed the Singular Velvet Sky Chrysanthemum and the Narcissus Jade Marrow Bone,

it seemed that Ye Yu could set his sights directly on a Ten Thousand Year Spirit Ring for his First Spirit Ring.

But after hesitating for a moment, Ye Yu still gave up on the idea.

The risk of crossing such an enormous cultivation-age gap to absorb his First Spirit Ring was simply too great.

Although the original novel said that consuming the Singular Velvet Sky Chrysanthemum could grant one an indestructible body,

it had never actually been demonstrated.

There was no way to determine whether consuming the Singular Velvet Sky Chrysanthemum and Narcissus Jade Marrow Bone could raise his Spirit Ring absorption limit by another five thousand years or so.

What if they could not?

And after consuming several immortal herbs in succession, their medicinal effects might weaken.

If he tried to absorb a Ten Thousand Year Spirit Ring, something might go terribly wrong!

Besides, it would be difficult to explain to Dugu Bo.

So in the end, Ye Yu decided not to consume the Singular Velvet Sky Chrysanthemum and Narcissus Jade Marrow Bone just yet.

He would wait until he had completely absorbed the medicinal power accumulated within his body from the Ink Jade Divine Bamboo Shoot, Octagonal Mysterious Ice Grass, and Infernal Delicate Apricot.

Only then would he consume the Singular Velvet Sky Chrysanthemum and Narcissus Jade Marrow Bone.

That way, the medicinal effects of the Singular Velvet Sky Chrysanthemum and Narcissus Jade Marrow Bone could be put to better use as well!

After finishing the Ice Fire Body Tempering,

Ye Yu had originally wanted to leave the mountain where the Ice and Fire Yin Yang Well was located at once and return to Heaven Dou Imperial City.

He wanted to ask Dugu Bo to help him hunt a Spirit Ring in the Star Dou Great Forest.

But he was still only a level-ten Soul Warrior.

Although his true cultivation had long since far surpassed that level due to fusing with the Blue Silver Emperor's Right Leg Bone and consuming the Ink Jade Divine Bamboo Shoot,

without absorbing a Spirit Ring, that Soul Power could not be displayed.

This left Ye Yu with no choice but to wait here helplessly.

Fortunately, Dugu Bo had given him a Storage Spirit Tool shaped like a green pouch, filled with all kinds of food.

Ye Yu did not need to worry about meals.

But counting the time spent on the Ice Fire Body Tempering, Ye Yu had forcibly suppressed his cultivation for three years already!

This time, because he needed strength,

Ye Yu yearned more than ever to break through as quickly as possible.

He was like a cicada buried deep in dark soil, lurking underground for more than a decade.

All for that final transformation!

Now, that day had finally arrived!

A butterfly emerging from its chrysalis, a fish leaping over the dragon gate.

The moment was now!

After waiting several days at the Ice and Fire Yin Yang Well,

Dugu Bo finally returned.

"Little Yu, after you consumed and refined those two ice-and-fire immortal herbs, did your Blue Silver Spirit Jade Vine Martial Soul evolve?"

Seeing that Ye Yu had successfully absorbed and refined the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot, Dugu Bo asked curiously.

In response, Ye Yu extended his hand and summoned the Blue Silver Spirit Jade Vine again, but shook his head with some regret.

"This time, it only gained some enhancements. There was no Martial Soul Evolution."

"That's a pity!"

Seeing that the Blue Silver Spirit Jade Vine Martial Soul after the Ice Fire Body Tempering had only grown thicker, with icy-blue and fiery-red patterns appearing across it, Dugu Bo could not help feeling somewhat regretful as well.

After that, Ye Yu brought up the real matter, hoping Dugu Bo could take him to hunt his First Spirit Ring.

"For your First Spirit Ring, are you planning to absorb the Spirit Ring of a Plant Spirit Beast with the Life Attribute, or one with exceptionally powerful vitality?"

Dugu Bo pondered.

"Then it would be best for us to go to the Star Dou Great Forest."

"Compared to the Star Dou Great Forest, the Plant Spirit Beasts in Sunset Forest are far inferior in both variety and cultivation age."

Having already accepted Ye Yu and sincerely regarded him as his grandson-in-law,

Dugu Bo took Ye Yu back to Dugu Manor first.

After having a servant inform Dugu Yan that he was taking Ye Yu to the Star Dou Great Forest to hunt a Spirit Ring,

Dugu Bo set off with Ye Yu for the Star Dou Great Forest.

After several days of travel,

once they arrived at the Star Dou Great Forest,

Dugu Bo led Ye Yu all the way into its inner region.

They began searching everywhere

for a Plant Spirit Beast Ye Yu wanted—one with the Life Attribute or exceptionally powerful vitality, and a cultivation age of around five thousand years.

At first, Dugu Bo had been completely against this.

After all, absorbing a Thousand Year Spirit Ring as one's First Spirit Ring was already unimaginable.

Absorbing a five-thousand-year Spirit Ring?

In his eyes, that was practically suicide!

But Ye Yu demonstrated the strength of his body after the Ice Fire Body Tempering.

When he circulated his Soul Power, his skin emitted a faint icy-blue and crimson glow.

Even when slashed hard with a sharp stone, it only received a white mark.

This left Dugu Bo utterly stunned, and he finally agreed.

After more than ten days of searching through the inner region of the Star Dou Great Forest,

Ye Yu finally found a Plant Spirit Beast that perfectly met his requirements.

It not only possessed the Life Attribute, but had a cultivation age of more than five thousand one hundred years—the Undying Grass!

This was an exceedingly rare Plant Spirit Beast. It resembled a shuttlecock in shape and had no stem.

It only had a cluster of long, narrow jade-green leaves packed together, their golden vein patterns looking mysterious and profound.

Its roots were deeply buried underground and could easily reach depths of several hundred meters.

Even if it were burned to ashes, as long as a small section of root remained, it could grow again. Its vitality was incomparably terrifying!

"The longest leaf is half a meter. This Undying Grass is just over five thousand years old."

"Grandpa, let's choose this one!"

Looking at the Undying Grass growing not far ahead, Ye Yu was unable to contain his excitement and anticipation at finally finding a suitable Plant Spirit Beast.

"Alright!"

Dugu Bo nodded and summoned the Jade Phosphor Serpent Emperor Martial Soul to possess him. Nine Spirit Rings immediately rose one after another beneath his feet, circling around him.

Because the Undying Grass possessed such powerful vitality,

even Soul Warriors far stronger than it would find it difficult to kill.

But for Dugu Bo, who wielded poison, he happened to be the perfect counter to a Plant Spirit Beast with such powerful vitality.

"First Spirit Skill: Jade Phosphorous Poison Fire!"

After summoning the Jade Phosphor Serpent Emperor Martial Soul to possess him,

Dugu Bo narrowed his eyes, shouted, and activated his First Spirit Skill. He condensed a ball of jade-green poison fire and shot it instantly at the Undying Grass.

The moment it was struck by the Jade Phosphorous Poison Fire,

the Undying Grass immediately burst into roaring jade-green flames. Its body trembled violently as countless roots whipped out from underground, frantically lashing at the poison fire burning over it.

But it was completely useless!

The Jade Phosphorous Poison Fire was no ordinary flame.

Poison fire—poison and fire were one.

As the poison corroded, the Jade Phosphorous Poison Fire continued to burn.

Even the Undying Grass's roots underground could not escape!

Under Dugu Bo's control,

the Undying Grass's underground roots were soon all burned away by the Jade Phosphorous Poison Fire.

Only the cluster of shuttlecock-like, narrow jade-green leaves streaked with golden threads and charred black remained above ground.

After Dugu Bo dispelled the Jade Phosphorous Poison Fire,

Ye Yu grabbed a large rock and walked up to the Undying Grass.

Aiming at the Undying Grass, he began smashing it wildly.

Very quickly, he smashed the Undying Grass into pulp!

At once, countless purple motes began drifting out.

Soon, above the "corpse" of the Undying Grass, a deep-purple Spirit Ring condensed.
