"Oops!"

The Demon King's expression changed drastically, and he turned to shout at the eight Demon Lords in the distance:

"Quickly, go and ask my two older brothers, the Sword Demon King and the Blade Demon King."

The eight demon lords' expressions changed drastically, and they all exclaimed in surprise, "What?"

Our Lord Magic Stone has actually been defeated!

Surprised, they quickly flew away to find the two older brothers of the Demon Stone King.

Lin Xiaofei glanced at them but ignored the eight demon lords who had fled.

"You want to kill me? Not so easy!" the Demon Stone King roared, "Demon King Battle Body!"

In an instant, a torrent of demonic energy surged forth from his body, and his body gradually grew larger, growing taller at a speed visible to the naked eye, transforming into a giant hundreds of feet tall.

At this moment, his body became tall and mighty, like mountains and rivers.

The Demon King Battle Body is the result of him activating the power of his demonic bloodline. This bloodline power allows him to grow larger and strengthen his body's defenses.

Rumble!

He waved his enormous hands, slapping away the endless sword energy that was flying towards him.

At the same time, due to the activation of the Demon King Battle Body, his body grew larger, making it impossible for him to fly in the air, and he had to fall to the forest floor.

Lin Xiaofei sneered: "That's it?"

At that moment, he rapidly waved his hands, unleashing a torrent of sword energy.

At this moment, the Demon Stone King was like a giant target, being bombarded by endless terrifying sword energy as if it were destroying everything in its path.

Rumble!

Although the Demon King of the Stones could disperse some of the sword energy with his hands, his enormous body made his movements slow.

Unbeknownst to them, the Demon Stone King's body had already been bombarded by a large number of terrifying sword energies.

In a short while, his chest had been bombarded by sword energy thousands of times, the destructive power of the sword energy penetrating into his body, the power of the sword light destroying his flesh and blood.

"Ah! My life is over!"

The Demon King of the Magic Stones had a ferocious expression on his face. Suddenly, he let out a miserable scream and his body crashed heavily into the forest, causing the earth to tremble.

Is he dead?

Lin Xiaofei stood in the void, panting heavily, looking down at the huge body of the Demon Stone King lying on the ground in the forest below.

Then, the enormous body gradually shrank, becoming a body a hundred feet, several tens of feet, and then three feet long.

At this moment, the Demon King's battle form, which the Demon Stone Demon King had unleashed, was shattered, and he lost all his breath.

Lin Xiaofei moved with lightning speed, leaping down and landing steadily beside the corpse of the Demon Stone King.

With a light flick of his arm, he casually removed a storage bag hanging from the other person's waist.

"Um?"

Lin Xiaofei immediately checked it and saw that the storage bag contained a large number of magical treasures.

After a careful examination, Lin Xiaofei's lips curled into a slight smile, and he said softly, "

That's wonderful!

"I never imagined that the Demon King's storage bag would contain over 5 million Demon Spirit Grasses!"

A surge of excitement welled up in Lin Xiaofei's heart, and he muttered to himself:

With these 5 million+ Demon Spirit Grasses, I only need to plant them in the Space Bead to give them the ability to accelerate cultivation, and then I can consume them directly.

In that case, I can cultivate the Eternal Sword Technique.

His "Eternal Sword" technique has already reached the entry level. Once unleashed, it possesses power comparable to a peak early-stage Nascent Soul cultivator.

He knew that if he could cultivate the Eternal Sword from the beginner level to the minor, major, and even perfect levels, the power of the Eternal Sword would become even stronger.

It even surpasses the power of the second level of the One Sword Heart Meridian.

Without hesitation, Lin Xiaofei waved his arm and released his powerful divine sense, taking out all five million Demon Spirit Grasses from the storage bag.

Immediately afterwards, he took a step and entered the spatial bead.

With a wave of his arm, he planted the Demon Spirit Grass in the soil inside the spatial bead, then pulled the Demon Spirit Grass out of the soil and neatly piled it beside him.

Then, Lin Xiaofei sat cross-legged, a slight smile playing on his lips, and said softly:

With these magical herbs, my "Eternal Sword" technique should be able to reach its perfect state.

With that, he waved his arm again, and the pile of demonic grass beside him flew into his hand as if dancing.

He opened his mouth and put the Demon Spirit Grass into it; it melted instantly upon entering his mouth.

In an instant, a surge of intense heat welled up within him.

Lin Xiaofei hurriedly activated the Eternal Sword cultivation method.

"Eternal Sword" is a complex and profound supreme sword technique. At this moment, Lin Xiaofei is fully utilizing the cultivation method.

In his mind, dozens, hundreds, and thousands of phantom images of sword energy appeared one after another.

Each illusory sword aura seemed to contain unparalleled power. The sword aura seemed to fill the entire void, changing in countless ways. Each sword aura contained the power of the laws of heaven and earth.

As Lin Xiaofei experienced the cultivation method of "Eternal Sword," various scenes of sword energy shooting out constantly appeared in his mind.

One after another, sword energies shot out, and Lin Xiaofei's mind was completely immersed in them, constantly comprehending the eternal power of the sword.

At that moment, Lin Xiaofei couldn't help but feel a sense of shock, and muttered to himself:

This Eternal Sword is far more powerful than the second level of the Heart Meridian Sword, and its profound mystery surpasses it.

Once the Eternal Sword is activated, its sword energy will inevitably contain the power of the laws of heaven and earth.

Once cultivated to its perfect state, the sword energy casually unleashed would undoubtedly be capable of matching the full power of a peak Nascent Soul cultivator's attack.

Buzz! Buzz!

At that very moment, the cultivation method of the Sword Heart Meridian frantically absorbed the energy transformed from the Demon Spirit Grass within his body.

As he continued to gain insights and understanding, he gradually came to know the secrets contained within the One Sword Heart Meridian.

In just 3 to 5 breaths, Lin Xiaofei seemed to have thousands, even tens of thousands, of methods for using sword energy flashed through his mind in the blink of an eye.

"Small success!"

He knew that he had already cultivated the Eternal Sword Technique to a minor level of mastery.

Without pausing, he waved his hand again, and the pile of demonic grass beside him reappeared in his hand, which he then put into his mouth.

Instantly, the Demon Spirit Grass transformed into a stream of heat, flowing through his body and rising in intensity.

Lin Xiaofei continued to fully utilize the cultivation method of the One Sword Heart Meridian, hoping to achieve complete success in cultivating the One Sword Eternity.

After consuming over 2 million Demon Spirit Grasses one after another, Lin Xiaofei realized that the Eternal Sword cultivation method was rapidly circulating within his body after absorbing immense energy.

A moment later, countless methods of sword energy breaking through the void, related to the eternal sword, resurfaced in his mind.

In a short period of time, he felt as if he had practiced the Eternal Sword Technique more than 50 million times.

Rumble!

At a certain moment, Lin Xiaofei seemed to hear a loud bang, and the countless sword qi phantoms in his mind transformed into a supreme sword qi.

A sudden realization dawned on Lin Xiaofei, and he couldn't help but smile, saying in a low voice:

"The sword's power is eternal; it has finally reached its pinnacle!"
