Gravel was everywhere along the awkwardly-shaped valleys.

　　After carefully cutting a huge reddish-brown rock, Shi Mu suddenly heard a violent roar coming from afar.

　　The sound shook the gravel on the hillside, causing it to roll down in a burst of smoke.

　　Shi Mu quickly retracted a few steps, squatting behind the giant rock, looking at the source of the sound.

　　In the depths of the valley before a huge bottomless cave, a giant bone elephant of more than ten feet was slamming left and right. It was jumping up and down, hitting its back in the process. From time to time, the rock walls and stones would pierce through its back.

　　Witnessing this scene, Shi Mu could not help but smile slyly. It reminded him of one particular black puppy in the small village. When summer was approaching, it would always circle around trying to scratch or bite its back due to the fleas in its fur.

　　Aside from the giant white bones of the big elephant, there was nothing special about it.

　　Suddenly, the bones swelled and spit glittering green fog from its mouth. The fog began to spray toward the surrounding land as one of the boulders fell on the other stone that was right in front of Shi Mu.

　　Shi Mu saw and quickly took cover.

　　Peng!

　　The green fog mist began to scatter and almost splashed onto Shi Mu.

　　As the boulder came into contact with the fog, its surface became covered with green slime. An irritating sound could be heard and suddenly the boulder was riddled with holes.

　　Shi Mu hastily grabbed onto the Heavenly Meteoric Black Iron Knife and took on a defensive posture.

　　Even after the fog sprayed out, the elephant continued to stumble left and right in an attempt to bite its own neck.

　　Seeing that he was not exposed, Shi Mu was only slightly relieved. He did not move closer but chose to continue observing from a safe distance.

　　The head of the white-boned elephant suddenly lowered, followed by a silent roar.

　　Shi Mu glanced for a moment and noticed a small crystal-clear figure on the head of the giant bone.

　　The figure only appeared faintly and then disappeared again.

　　Looking at the empty bones of the giant elephant, Shi Mu squinted and rubbed his eyes, as if it might have just been a dream.

　　The next moment, Shi Mu found that there was an obvious crack in the giant elephant’s skull.

　　Shi Mu’s eyes flashed and he suddenly found that on the ground below the tail of the elephant was a petite skeleton.

　　The skeleton was a vibrant dark purple. From afar, it looked identical to the bones of the giant elephant though it was smaller in size, almost looked like an ant.

　　Shi Mu was particularly fascinated. The skeleton of the little scorpion had a translucent color like a crystal, with two bone claws like translucent knives.

　　The crystal skeleton held the two transparent knives in its hands and took a bowing position.

　　On the side of the giant elephant, a gap was revealed and the crystal skeleton immediately jumped out and landed on the top of the giant bone elephant. With a full-forced strike of its two short knives, a crack could be seen on the giant elephant’s skull.

　　Shi Mu looked at the crack and how it extended as the seconds passed by. His heart could not help but wonder…

　　If not for the techniques and skills he possessed, it would have been hard for him to trace the moves of the crystal skeleton.

　　The crystal skeleton did not hesitate to attack when given the chance, and he would immediately jump down to take cover when it got too intense. He hid in a crouching position to wait for the next opportunity to attack.

　　After so many attacks, the white boned elephant was now filled with cuts and bruises from the tip of its skull to its limbs.

　　“This is a natural assassin!” Shi Mu secretly admired in his heart.

　　Being invisible, good at hiding in plain sight and quick in attacking, it was really the best choice for an assassin.

　　When the elephant was exposed again, the crystal skeleton flew out and attacked it with full strength. As the knife blades passed through the giant elephant, the bones were again hit.

　　Only this time, it did not jump back to the ground after succeeding. The white-boned elephant fell on its back, with both knives plunged into its spine.

　　The giant elephant had been tortured by this invisible opponent to the point that it was going crazy, almost losing its rationality completely. With a roar, a huge green giant elephant about seven or eight feet emerged out of thin air.

　　The giant elephant opened up its mouth and began to spout sticky green mist.

　　But after making this move, the shadow elephant crashed.

　　The crystal skeleton seemed to have been expecting it. Before the green fog reached it, the skeleton jumped off the giant elephant’s back and escaped the green mist.

　　This viscous green fog seemed to have a corrosive effect on the bones of the giant elephant. It fell on its back as noisily as cymbals, and several bones that were already cracked immediately broke into pieces.

　　Bang!

　　The giant elephant’s bones were broken into several pieces and it was left paralyzed on the ground.

　　At this point, the assassination by the crystal skeleton seemed a success. The elephant was still fighting for its life while suffocating. Only when the purple soul fire in its eyelids faded away did the crystal skeleton walk forward step by step.

　　The crystal skeleton walked to the head of the elephant and slammed the double knives into the eyes of the giant bones for a fatal blow.

　　However, when it unveiled its double knives, the soul fire in the elephant’s eyes suddenly flashed. The crystal skeleton was shocked and immediately pulled its hands back. At the same time, the elephant jumped to the side, and its bones gradually became transparent.

　　It did not completely hide its shape; a black light curtain covered it from the top of the head, and the crystal skeleton enveloped it.

　　A black brick suddenly appeared in midair, emitting dark light. It was none other than the Fallen Angel Desk.

　　The crystal skeleton squatted under the black light and began to tremble.

　　“Hu…”

　　Two fireballs flew out from a distance, landing on the two legs of the crystal skeleton and smashing it to pieces.

　　In the air, the dark lines from the Fallen Angel Desk shone bright and the shadow of the crystal skeleton disappeared.

　　Shi Mu was overjoyed and rushed to explore the Fallen Angel Desk.

　　He was shocked to find there was no trace of the crystal skeleton anywhere.

　　Shi Mu’s brows wrinkled as if he sensed something. Suddenly, a figure appeared not far away.

　　Looking back, a short translucent figure appeared in the place where he was standing. He held the knife and inserted it into the ground.

　　The crystal skeleton leaped into the air and attempted a sneak attack. If Shi Mu had not avoided it in time, he would have been decapitated.

　　Just as the crystal skeleton stood up and tried to hide again, Shi Mu obscured his appearance by turning into a blue shadow and aimed his knife at the crystal skeleton.

　　The crystal skeleton was taken by surprised. It quickly blocked Shi Mu’s attack with its two short knives but they were pressed to the ground by Shi Mu’s great strength.

　　Shi Mu slammed its skull with the white wind and swayed to the side.

　　Crystal skeleton saw this and immediately climbed up to find a way to escape.

　　Just then, the soles of its feet flashed and burst in green light.

　　Amidst the light, several green vines flew out, and the crystal enamel was tied up.

　　Not far away, Shi Mu’s eyes flashed as he firmly locked eyes with the crystal skeleton.

　　The black light flashed above the top of the skull. The Fallen Angel Desk flickered a little and flew out of a portal of black light.

　　This time, the crystal skeleton had no place to run and was sucked into the Fallen Angel Desk.

　　Shi Mu quickly released his knowledge into the Fallen Angel Desk. Using the soul-snaring spell, he forced the crystal skeleton into a contract.

　　After it was done, Shi Mu was relieved.

　　His original intention was to capture the white-boned giant elephant with the Fallen Angel Desk. However, he unexpectedly discovered this short crystal skeleton with the potential of an assassin. If it could be used well, it would be beneficial in the future. Eventually, it would be made even more powerful.

　　Shi Mu was delighted with his catch and returned to Darkwater Lake.

　　One day later, when Shi Mu returned to the vicinity of the Darwater Lake, he found the situation there was almost the same as when he left.

　　The dead creatures around the lake still followed Yan Luo’s instruction, not allowing anyone close, but for Shi Mu, they did not try to stop him.

　　Shi Mu stood in front of the lake and looked up.

　　Yan Luo was still in the lake, whereas Wu Ye still maintained his previous position, self-consciously sucking the red mist floating on the surface of the lake.

　　Speaking of which, the Dead Spirit World was filled with unchanging scenery. A long stay might prove boring.

　　Shi Mu looked at Wu Ye for a long while and raised his eyebrows when something caught his sight. Suddenly, he remembered the secret library of Heaven Ascension Peak. He had yet to open it.

　　Based on the rumor, the secret library of Heaven Ascension Peak contained the mysterious inheritance left by the White Ape King. Breaking through the holy order, could this be the wooden box that contained it?

　　As soon as he thought about it, Shi Mu’s excitement grew.

　　Although he had acquired the blood of the white ape and the blood of the Azure Ape King, it had little benefit.

　　He waved the wooden box out of the ring and noticed it felt heavy.

　　The wooden lid was tightly shut and a few silver plaques sealed it closed. Shi Mu put the box in front of him and pulled the corner of the silver plaque.

　　As he removed the seal, the silver symbol began to shine slightly, and the gloss on the top had completely dimmed.

　　A look of surprise came to his face. He could not believe how easily the box was opened.

　　The rune above the silver symbol was more complicated than the highest graded symbol he could draw. Shi Mu did not expect it could be removed without any effort.

　　“Is it because the symbol has gradually become invalid due to time?” Shi Mu secretly guessed, but in a way, it also saved him the trouble.

　　When Shi Mu removed the last symbol on the box, the whole wooden box suddenly emitted a golden light. With a bang, the box flew up and its size began to increase.

　　In the blink of an eye, the wooden box which at first was the size of a person had now grown to the size of a house.
