The river of bones flowed, the wind and sand overflowed, and the extremely noisy and chaotic roar echoed in it, and the sand demon puppet controlled by Jack shook its head slightly at this moment, and the human leg bone bitten by it ignited a ferocious white fire.

"I ...... I...... I ......"

The voice was unusually sluggish, and a faint call continued to come from the leg bones, and when the white fire completely ignited it, a very hazy male figure briefly flashed, and then the bones in the sand demon's mouth were completely shattered.

"Huh?!failed?wait......"

Jack's body frowned slightly, and through his hazy vision, he could vaguely see the fragments of leg bones gathering rapidly, but in a few breaths, they bonded together and reconstituted into a tiny, pocket-sized human bone.

The white fire was enveloped and entangled, the bones were white and bloody, and the small human bone appeared in the air and immediately jumped back into the mouth of the sand demon puppet, it clutched the hideous fangs and began to absorb the spiritual power infused by Jack, as if it did not intend to leave here.

"I ...... Need...... To give...... Obedience ......"

The human skeleton reluctantly transmitted the voice to Jack, who had just been born with wisdom but was no longer weak, and was thirsting for evolution and strength, and the hazy instinct told the puppet in front of the undead that it could help him.

Splitting the soul fire, at the head of the pocket human bone, a darker white fire was divided into two halves, and half of them flew directly into the core position of the sand demon puppet, which also made the body controlling it a little surprised.

"This little guy is not weak, he even knows how to divide the 'soul fire' to exchange power, but what was that shadow just now? The leg bones are mortal, and the first voice that came out seemed to be a female apprentice, but the shadow just now was a male ......"

Jack's body frowned, he continued to pour spiritual power while eating in silence, through the transmission of the sand demon puppet, pure spiritual power was poured into the bones, and at the same time, a large amount of bone crushing powder was also dragged over.

The air trembled, and the aura of the pocket human bones soared, from the level that ordinary mortals could destroy it all the way to the wizard's apprentice, and its size was gradually expanding by devouring bone meal.

Roar~

The human bone roared wildly, and as it approached its adult, it broke away from the sand golem on its own, but with its divided 'soul fire', Jack's spiritual power continued to be transmitted.

Unlike the 'remnant fire' that could be extinguished at any time at the beginning, the 'soul fire' of this human bone burned vigorously in its head and the puppet's body, and some special connection tied it together.

"This is?!'Soul Fire' seems to be similar to a magic contract after being divided, but the binding force doesn't seem to be high, and if you don't have a certain range, you can't control and perceive it. ”

With a slight groan, Jack's body began to move, and he walked towards the archive of the large gathering place, while the new undead who had been born in the other half roared and rushed towards the 'River of Bones', and a large number of low-level undead and broken bones were smashed and smashed by it.

Eating like crazy, the newborn undead began to devour the 'soul fire' of the same kind, even a little spark did not let go, it is very obvious that the wisdom of this skeleton is much higher than that of the same level, and only undead creatures close to wizards will hunt for food on their own.

"Okay, your name is 'Leg Bone', eat here obediently, don't move around or leave at will. ”

After Jack gave a simple order, the 'leg bone' nodded slightly, and the spiritual power infused by the other party was like a fuel oil, and its 'soul fire' was able to gain high wisdom and rapid evolution because of this.

Without saying anything more, Jack began to turn his attention to the other two bones, the skull of the silver gerbil and the spine of the large sand lizard, and with the experience he had just made, he began to repeat what he had just done, only this time with mental power at the same time.

For an hour, two hours, three hours, from noon until dark, Jack continued to infuse spiritual power, although long-distance control wasted a lot of power, but the undead creatures devoured the same kind of evolution characteristics made up for it.

"Well, that's all for now. ”

Slightly tired, Jack's body rubbed his eyes, he held an ancient book inlaid with porcelain tiles and sighed slightly, at this time the clone puppet was followed by three behemoths, begging and dissatisfied voices made his brain tremble.

With a hissing and a low roar, a humanoid skeleton nearly ten meters tall shook its head, and a light blue 'soul fire' with arcs and frost was beating and trembling on it, faintly, its body shimmering with bloodstained broken armor.

"No, you can't eat it, why? Why? Forbidden, eat?"

The skull swayed, and the massive humanoid skeleton looked anxiously at the 'River of Bones', behind which a zombie silver rat with bony wings and a transparent hazy ghost monitor lizard watched the river with equally greedy attention.

Frowning and scrutinizing, the sand demon puppets walked in circles in front of these three undead creatures, after a long time of spawning and strengthening, they had gained strength close to that of wizards, and even Jack's own body would feel hot hands and scratch his head under the increase of the 'Undead Wave'.

"It's not easy to control, the earliest spawned 'leg bones' and monitor lizard vertebrae are fine, and the silver rat skull is so different that the zombie is a little out of control, it may be that there is the most consciousness and soul left in the skull, and it is very troublesome to control. ”

Jack manipulated the sand demon golem to swing its forelimbs, and after a slight shock, the three undead creatures retracted slightly, and the silver rat with bone wings seemed to want to abandon the split 'soul fire' and rush into the bone river.

With a strong desire to devour, these undead creatures have an extraordinary thirst for 'food', and the 'River of Bones' not far away is the best place to eat, and Jack's orders are to restrain and restrict them.

"Go east, and when you reach the location, you can eat quickly, and then I will make you stronger!!"

The sand demon puppet transmitted Jack's spiritual message, and the undead creatures who had gained a lot of wisdom nodded silently, at this time their strength had surpassed that of this clone, but because the split soul fire could not disobey its orders.

Of course, those 'soul fires' that have split out can't restrain them forever, as long as they are promoted to the wizard level, most of them will lose their effect, but as long as there are elite undead piled up in the east, it is enough, and instinct will guide them to make a big fuss when the time comes.

Through this experiment of infusing spiritual power, he also understood that the wisdom of the undead creatures he gave birth to was much higher than that of the same level, and compared to those muddy bones, the desire and speed of the three undead to promote themselves were more than a hundred times faster.

If it weren't for Jack's intentional control, these three guys would probably have been promoted to the wizard level, and even if they were prevented from eating their own kind in the 'Bone River', their aura fluctuations were gradually increasing, and it was only a matter of time before they broke through under the shroud of the 'Undead Waves'.

"Nine days to go......"

Jack's body whispered, the sand demon puppet was giving birth to new undead at this time, and a large number of low-level undead with wisdom were thrown to the edge of the bone river, and they were eating their own kind while walking against the river, and the extremely faint sound of the waves was also faintly heard......
