It's a valley, a waterhole to be exact.

The water is crystal clear, tranquil and deep, like a giant sapphire.

On one side of the valley, a waterfall about 20 meters wide spans the mountain wall nearly 200 meters high like a jade belt, and the rumbling sound is caused by its impact on the waterhole.

The waterfall pours out and hits the pool, splashing countless splashes, the clear water vapor comes to the face, and the moist air is refreshing and very comfortable.

The Killing Knight was quietly outside the waterfall, although he didn't know what the Holy Son was doing inside, but it was an order from the Holy Son to protect the Dharma.

"The Holy Son came here after the killing god left, which means that this place is very likely to have a lot to do with the killing god."

"It's even very likely that it's the god-killing retreat, or the place where the treasure is buried!"

The Killing Knight guessed in his heart, and at the same time, he was also vigilant.

If it was really as he had guessed, then once the God of Killing noticed the situation here, he would definitely be furious, and there would be a big battle at that time.

Although he is not afraid of that killing god, but with Fang Yuan, who is dragging his feet, the killing knight may not be able to fire at full power.

Therefore, the killing knight is still on guard, and once the crisis comes, he will leave directly with Fang Yuan.

I can't beat you, I can't outrun you!

The Killing Knight was on guard, while Fang Yuan, who was in the waterfall cave, laughed loudly.

Because of the night, the environment in the cave can be described as pitch black, but in the eyes of Fang Yuan, who opened the writing wheel eye, it was no different from the day.

Sharingan's powerful insight is enough to give him insight into everything in the cave.

There are not many furnishings in the whole cave stone room, some of them are empty, but just below the stone hole above, there is a small soil bag, on which a slender blue silver grass flutters in the wind.

The blue silver grass looks longer than ordinary grass blades, and the most peculiar thing is the golden fine lines on the grass blades, which look extremely noble.

That's right, this special Blue Silver Grass is none other than the 100,000-year-old soul beast of the past, the Blue Silver Emperor!

Fang Yuan's hand flicked the branches of the Blue Silver Emperor, the Blue Silver Emperor seemed to feel the touch, the golden thread on the blade of grass seemed to come alive, and in the slight rhythm, the golden light rippled like water waves.

"There is no resource supply, no soul power infusion, and a closed life of more than ten years of darkness."

Fang Yuan caressed the Blue Silver Emperor, and a sneer and mockery appeared on the corner of his mouth: "If I hadn't known that this Blue Silver Emperor was Tang Hao's wife, I would have thought he was a prisoner!" ”

This place seems to be good, the mountains and rivers are beautiful, and the natural harmony is a place, but it is outside!

In this stone chamber, not to mention the landscape, even the sunlight does not shine in, and the entire space is completely wrapped in indestructible rocks.

It can be said that except for this handful of loess, there is no place in the entire stone chamber that can allow this Blue Silver Emperor to grow.

Isn't this kind of environment a cage that is completely created for the Blue Silver Emperor?!

Fang Yuan caressed the Blue Silver Emperor, feeling unworthy in his heart.

But the purpose of his trip was not that.

Fang Yuan caressed the Blue Silver Emperor for a moment, then looked at the stone wall on one side.

The powerful insight of the writing wheel eye had already discovered the difference between this stone wall, and with a palm of his hand, a thick soul power fell on it, and the stone wall suddenly made a dull sound.

"What's the matter, Holy Son?"

The killing knight outside heard the noise and asked with some concern.

"Nothing."

Fang Yuan responded loudly, but his eyes were staring at the thing that fell out of the stone wall.

It was a black box, in the shape of a long strip, about one meter and a half long and one foot wide.

Fang Yuan used his soul power to grab it, but the feeling of starting it was very heavy, enough to weigh more than two hundred catties!

With a flick of his finger, the black box suddenly made a muffled sound.

Fang Yuan's eyes lit up, the excitement in his heart was unbearable, and his hands even trembled a little.

Almost impatiently, Fang Yuan directly opened the pitch-black box.

In the pitch-black box, a right leg bone was quietly placed in it.

Among the six soul bones that can be loaded on a person's body, the right leg bone is undoubtedly ranked lower.

But the right leg bone in front of me looks so different!

The whole body of this right leg bone is crystal clear blue-gold, and there seems to be a little starlight twinkling inside.

The most peculiar thing was that the moment he saw this right leg bone, Fang Yuan actually felt a feeling of fresh life.

Seems...... It's as if this right leg bone has life!

"What a rich breath of life!"

Fang Yuan took a deep breath, he had not touched the soul bone, although he already had an external soul bone, and that external soul bone was still from a top-level soul beast, the Dark Gold Dreadclaw Bear.

However, the external soul bone was directly integrated into his body when he absorbed the soul ring, and he had not seen what the soul bone looked like.

And at this moment, Fang Yuan saw a soul bone for the first time, and it was a soul bone with a year of up to 100,000 years!

That's right, this right leg bone is the right leg bone of the Blue Silver Emperor from the 100,000-year-old Blue Silver Emperor!

In the original work, this soul bone brought great convenience to Tang San, not only improving his soul power greatly, making the redundant power in his body completely merge with his physical body, but also bringing Tang San two soul skills.

Soul skill 1: The wildfire burns inexhaustibly, and the spring breeze blows and grows again (the body repairs itself, even a severed limb can grow on its own, in the blue silver field and in the place full of blue silver grass, it is extremely beneficial to this soul skill)

Soul Skill 2: Flying (Additional Flying Ability)

And at this moment, this soul bone was quietly presented in front of Fang Yuan's eyes.

"Gollum!"

Fang Yuan's eyes stared at the Blue Silver Emperor's right leg bone.

The value of the 100,000-year soul bone is not lower than that of the 100,000-year soul ring at all, and it may even be because of the particularity of the soul bone, its value is even higher than the 100,000-year soul ring!

After all, absorbing the soul ring has the risk of failure and backlash, while absorbing the soul bone does not have the slightest side effect.

Fang Yuanqiang endured the greed in his heart, restrained the desire to absorb it directly, and waved his left hand, putting it into the Ouroboros bracelet.

Although it is safe to absorb the soul bone, because the soul power in the soul bone is too large, it often takes a lot of time to complete the absorption.

With the importance of the Blue Silver Emperor, Tang Ritian would definitely come back to check it out, Fang Yuan didn't want to be caught by Tang Ritian's goods when he was halfway through the absorption.

With the soul bones in hand, the purpose of Fang Yuan's trip can be regarded as achieved.

Fang Yuan turned to leave, but just as he was about to leave the stone room, a feeling of lightness came from his left hand.

Fang Yuan frowned slightly, and turned his head to look.

only to find that the gently swaying blue silver grass actually took the initiative to move at some point.

A slender blade of grass gently stretched and wrapped around Fang Yuan's left hand, and at the same time, an extremely faint spiritual fluctuation was transmitted.

"It's ......"
