In the valley, the ground is full of gravel and hideous shapes.

After Shi Mu cautiously walked around a huge reddish-brown boulder, he suddenly heard a violent roar not far away.

The sound shook the small gravel on the hillside, sending up puffs of smoke and dust.

Shi Mu hurriedly took a few steps back, crouched behind the boulder, and looked towards the place where the sound came from.

In the depths of the valley, in front of a huge bottomless cave, a huge white bone giant elephant with a huge body, five or six zhang high and more than ten zhang long, was rushing left and right, jumping up and down, hitting the surrounding rock walls and rocks with his back, and turning back from time to time, stabbing straight at the back with a pair of his own bent huge tusks.

Shi Mu looked at this scene, his eyes showed a look of surprise, and he couldn't help but think of the little black dog in the small village where he grew up, and when it came to summer, it always went around in circles to bite the lice on his back.

But looking at the white-boned giant elephant again, there is nothing special on its back except for the thick bones.

Suddenly, the white-boned giant elephant shook its bone nose, and three or four clouds of green mist suddenly erupted from its mouth, spraying towards the surrounding clearing, and one of them slammed into the boulder in front of Shi Mu.

Seeing this, Shi Mu hurriedly jumped away from it.

"Bang"!

The green mist scattered and sputtered, almost splashing down on Shi Mu's body.

After the green mist dispersed on the surface of the boulder, the huge rock surface was actually covered with a layer of green film, and the sneering sound was loud, and it became full of holes in the blink of an eye.

Shi Mu's right hand clenched the black knife of the meteorite iron and assumed a posture of vigilance.

However, after the white-boned giant elephant spewed out the green mist, it did not make any follow-up moves, and continued to rush left and right, biting towards its own back.

Seeing that he was not exposed, Shi Mu relaxed slightly, but he did not move any further, but chose to continue to observe in the same place.

At this moment, the white bone giant elephant's head suddenly sank, followed by a silent roar.

Shi Mu's eyes flickered, and he suddenly saw a short and crystalline figure that seemed to flash over the head of the white-bone giant elephant.

The figure only vaguely appeared, and then disappeared again.

Seeing that the head of the white bone giant elephant was empty, Shi Mu rubbed his eyes, feeling a little stunned, thinking that he was really dazzled by the mistake.

But the next moment, Shi Mu suddenly found that there was an obvious crack in the eye socket of the white bone giant elephant's skull.

Shi Mu's eyes flashed with gold, and he quickly glanced at it, and suddenly found that on the ground below the tail of the white-boned giant elephant, there was a short skeleton lying on his stomach.

This short skeleton has a light purple soul fire in its eyes, and its cultivation is similar to that of a white bone giant elephant, but its body size is less than one-third of that of an ordinary skeleton soldier, and it looks very thin, like an ant in front of the white bone giant elephant.

What particularly surprised Shi Mu was that the bones on the top and bottom of this little skeleton were as translucent as crystal, and each of its two bone claws held an equally translucent bone short knife.

The crystal skeleton held the two transparent bone knives in his hands upside down, half-arched, as if looking for an opportunity to strike.

Just on the side of the Bone Giant Elephant's body, a gap was revealed, and the crystal skeleton immediately flew out and landed on the top of the Bone Giant Elephant's head again, and the two short knives stabbed down violently at the same time, inserting into the crack that had already appeared.

Shi Mu watched the crack on the skull of the white-boned giant elephant extend to both sides and expand several times, and his heart couldn't help but feel terrified.

If it weren't for the blessing of his spiritual eyes, I am afraid that he would not have been able to discover the whereabouts of this crystal skeleton at all.

Except for the moment of attack, its body is almost transparent, and it is extremely difficult to detect.

The crystal skeleton struck a blow, but it didn't stop, jumping down again and disappearing, lying on the ground in its original position, waiting for the next attack.

After doing this a few times, the white-boned giant elephant was covered with wounds, and its limbs and skulls were cracked one after another.

"This is simply a natural assassin!" Shi Mu secretly admired in his heart.

Able to be invisible, good at hibernation, and ruthless, he is really the best choice for assassins.

When the white bone giant elephant showed its flaws again, the crystal skeleton flew out again, and where the sword light of both hands passed, the sound of bone shattering sounded, and the white bone giant elephant was hit hard again.

Only this time, he didn't jump back to the ground after he succeeded, but his body fell on the back of the white bone giant elephant in a few flashes, holding the knife in both hands, and stabbed into the scarred backbone of the white bone giant elephant.

The white-boned giant elephant had already been tortured by this invisible opponent and was about to go crazy, and it lost its mind, and let out a roar of rage when it looked up to the sky, and above its head, a huge green giant elephant phantom with a height of seven or eight feet appeared out of thin air.

Then, the giant elephant's phantom mouth opened, and a large patch of viscous green mist surged out.

But after making this move, the phantom collapsed.

The crystal skeleton seemed to have expected it, and before the green mist could reach it, it jumped off the back of the giant elephant in a flickering shape, avoiding the green mist's spit.

The sticky green mist seemed to have a corrosive effect on the bones of the white bone giant elephant itself, and as soon as it landed on its back, a sneering sound sounded, and several bones that were already full of cracks immediately broke apart.

I heard a "boom" sound, and the back of the white-boned giant elephant was broken into several pieces, and the huge body collapsed to the ground.

At this point, the assassination operation of the crystal skeleton had basically been successful, but it was still calm, until it saw the purple soul fire in the eyes of the white bone giant elephant began to sway and dim, and then suddenly appeared and stepped forward step by step.

The Bone Giant Elephant was at the end of its powerful crossbow, and the Crystal Skull walked to the head of the giant elephant, poked out its two knives, and slammed into the eye socket of the White Bone Giant Elephant, as if it wanted to deal a fatal blow to it.

However, as soon as the twin knives were stretched out, the crystal skeleton's eyes flashed violently, and it suddenly withdrew its hands, and at the same time, its body jumped to one side, and the bones around it gradually became transparent.

But before it could completely hide its form, a black curtain of light had already shrouded the crystal skeleton from under the top of its head.

The black light curtain came from the black bricks that suddenly appeared in mid-air, and it was none other than Falling Sendai.

The skeleton trembled under the black light, but its feet were strong and it did not kneel.

"Whew"!

Two fireballs flew out from a distance and smashed into the crystal skeleton's two leg bones, knocking it to its knees.

The dark lines of Sendai in mid-air lit up, and the black light rolled back, and the figure of the crystal skeleton disappeared with it.

Shi Mu was overjoyed, and hurriedly used his spiritual power to explore the fallen Sendai.

But at this glance, he was suddenly startled, because there was no crystal skeleton in the space of Falling Sendai.

Shi Mu frowned, and the next moment he seemed to realize something, and his figure shook violently and appeared not far away.

Looking back, a short, translucent figure appeared where he had just stood, holding a knife in both hands and plunging it into the ground.

The crystal skeleton jumped down in the air, wanting to sneak attack, if it hadn't dodged in time, I am afraid that it would have been broken by the two bone short knives at this time.

Just as the crystal skeleton stood up and wanted to hide its form again, Shi Mu turned into a blue shadow, and a blur appeared in front of it, and the black knife in his hand slashed forward.

The crystal skeleton was startled, and the two short knives overlapped to hold Shi Mu's black knife, but it was pressed to the ground by its huge force.

Shi Mu opened his mouth suddenly, and a white air stream hit the crystal skull, causing him to shake his body and fall to the side.

Seeing this, the crystal skeleton knew that it was invincible, and immediately got up, wanting to turn around and flee away.

At this moment, the green light on the soles of his feet flashed, and a green talisman appeared here at some point, and burst directly.

In the green light, several green vines flew out, binding the crystal skeleton into a knot.

Not far away, Shi Mu's eyes flashed with gold, still firmly locked on the crystal skeleton.

Then a black light flashed above the skeleton's head, and the Falling Sendai flashed, and a roll of black light flew out of it.

This time, the crystal skeleton's feet were restrained, and there was no way to avoid it, and it was finally included in the Falling Sendai.

Shi Mu hurriedly released his divine sense and entered the Falling Immortal Terrace, urged the Soul Detention Technique, planted his own spiritual imprint on the crystal skeleton, and forcibly signed a contract with it.

After doing all this, Shi Mu secretly breathed a sigh of relief.

Speaking of which, his original intention of coming here was to capture the white-boned giant elephant into the Falling Sendai for his own drive, but he accidentally discovered this crystal skeleton with short stature and assassin potential, if it can be used well, it will definitely be able to exert a lot of power when facing the enemy in the future.

Shi Mu was overjoyed with this harvest, and did not stay here for long, and soon returned to the Stygian Lake.

A day later, when Shi Mu returned to the vicinity of the Stygian Lake, the situation here was almost the same as when he left.

The necromantic creatures around the lake still obeyed Yan Luo's orders and did not let anyone approach, but for Shi Mu, they turned a blind eye and let him go in and out.

Shi Mu stood in front of the Stygian Lake and looked around.

Yan Luo was still in the lake, not coming out, and Wu Ye still maintained his previous posture, inhaling the red mist wafting out of the surface of the lake by himself.

Speaking of which, the sky is dark, the ground is lifeless, and the surrounding scenery is unchanged, and it is really a bit boring to watch it for a long time.

Shi Mu looked at it for a long time, his eyebrows raised, and suddenly the wooden box he got in Ling Tianfeng's secret vault sounded, and he hadn't opened it yet.

It was rumored that Ling Tianfeng's secret vault contained the mysterious inheritance left by the White Ape King to break through the Holy Rank, could it be in this wooden box?

As soon as he thought of this, Shi Mu's eyes showed excitement.

Although he has already obtained a drop of the essence blood of the white ape, and even more so the essence blood of the Heavenly Ape Demon King, no one will have too many benefits.

With a wave of his hand, he took the wooden box out of the ring, feeling a little heavy in his hand.

The wooden lid is tight, and a few silver talismans are pasted on it, which seals the lid more tightly.

It seems that in order to open the lid, these talismans must be removed first.

Shi Mu groaned slightly, put the box in front of him, and pulled up the corner of the silver talisman with his hand, and was about to silently luck his true qi, but with a slight pull of his fingers, he took off the silver talisman.

The silver talisman shimmered slightly, and the luster on it completely dimmed.

He was stunned, a little incredulous.

The runes on this silver rune were far more complicated than the high-grade runes he could draw, but he didn't expect to remove them without much effort.

"Could it be that because of too much time, the talisman has gradually become invalid?" Shi Mu secretly guessed in his heart, but in this way, it would save trouble.

When Shi Mu removed the last talisman on the box, the entire wooden box suddenly emitted a golden light, and then, with a hula, the box flew into the air, and its volume suddenly increased.

In the blink of an eye, a wooden box the size of a human head turned into the size of a house.
