After a while, the skeleton's soul perception also detected Kane's presence.

Immediately, it became alert, cautious of any ambush nearby.

Slowing its steps, it approached Kane unhurriedly.

Seeing this cautious skeleton, Kane just smiled, standing still without making any moves.

He said nothing, waiting for the skeleton to sense and examine the surroundings.

Watching Kane, the skeleton remained vigilant, continuously checking for any signs of ambush around.

After ensuring there was none, it didn't immediately signal.

The skeleton looked at Kane and said, "We haven't been apart for long, have we? Did you find a certain way so soon to call us back?"

Regarding the skeleton's caution, Kane didn't say much, directly taking out a bone fragment from the space equipment and pinching it between his fingers, shaking it in front of the skeleton.

"I just went to verify with Facundo, I wonder if you recognize this thing and can sense the aura on it."

Although the skeleton had never seen this bone fragment, it was very familiar with Facundo's soul aura that entwined it.

The faint soul aura on it belonged to the necromancer who once contracted with him, forcibly controlling him.

It seemed that this human indeed had a connection with Facundo.

Because the aura was very fresh, it seemed to have just entwined recently.

It roughly understood the use of this thing.

It extended its bone claw, making a swiping motion towards the space.

An inaudible sonic wave was transmitted through the space.

Letting the three undead afar feel the signal he sent.

"Rotten bone signaled, there's no ambush and it's safe, let's go."

After confirming there was no danger, the zombies relaxed, then hurriedly headed towards the skeleton's location.

Kane watched the invisible spatial fluctuations. 𝙛𝓻𝒆𝓮𝒘𝙚𝙗𝒏𝙤𝙫𝓮𝒍.𝓬𝒐𝙢

The skeleton's rule should be related to space, and the level of mastery is absolutely high.

It truly is a formidable rule.

What about the few undead above him, how powerful are they?

Soon, Kane sensed several other undead quickly approaching.

Seeing Kane, their soul fluctuations remained wary.

The few undead quickly surrounded the metal skeleton.

Seeing all the undead gathered, Kane directly tossed the bone fragment over.

The metal skeleton immediately caught it, clenching it in its hand.

The nearby undead instantly felt the familiar aura emanating from it, focusing all their attention on it.

"Isn't this... meant to sign?"

The ghost instantly recognized the bone fragment, unable to resist speaking.

"Just re-signing the contract, isn't this what we desire? Why hesitate?"

The zombie spoke, directly reaching out to tap the bone fragment.

Its action showed no hesitation.

Soon, a piece of its soul fragment flew towards the bone fragment, firmly imprinting on it.

Kane seemed to feel something, immediately taking out a contract book from the space equipment.

The contract book was flipping itself, and the opened page was precisely the chapter of the contract with this zombie.

It slightly glowed, with contractual markings and rules being restored again.

Light mist floating on the array showed that the contract was successfully linked again.

This zombie truly acted decisively, reconnecting the contract, severing the freedom it had gained?

The few undead were somewhat surprised by the zombie's decisiveness, but said nothing, instead contemplating themselves.

The second to extend a hand and repair the contract was the most powerful metal skeleton.

Seeing the two strongest already signing the contract, the ghost and the eye demon had nothing else to consider.

They quickly extended their soul fragments to renew the contract.

When all four undead had signed the contract, Kane's contract book restored four contract pages.

Reinstating its efficacy.

Then the bone fragment that absorbed their soul fragments and renewed contracts transformed into a mass of green mist, manifesting Facundo's specter.

Covered in a magic robe and holding a giant bone scepter.

Scarlet eyes in a face like black mist stared at the four undead.

"Very well, I thought there would be no loyal ones, but your actions surprised me."

Only to hear the metal skeleton faintly say, "Willingness to renew the contract isn't due to our loyalty, but rather because we have no other choice, right?"

"Hahaha, it's fine, regardless of why you're loyal, as long as you're loyal, it's enough."

Facundo said indifferently.

Then spoke to these four undead, "For now, just obey Kane's orders, and after this matter, Kane will lead you to me."

After speaking, he turned and nodded to Kane, "Then the rest is up to you, Kane."

Kane just smiled and nodded, not saying much.

"Then, this is the reward for the loyal ones, accept it gratefully."

Facundo turned to speak to the four undead, then his whole body dissolved, transforming into four wisps of smoke, crashing into their bodies.

The undead stood still, their souls trembling and swelling continuously.

Kane could feel that the strength of these undead was rising.

Their power had advanced a notch.

Once the souls of these undead calmed down, they all checked their bodies.

This was exactly why they were loyal.

"Have we lost our freedom again?"

The zombie looked at its withered arm and rasped.

"Freedom was never what we yearned for; there's nothing to lament about."

The metal skeleton said this and then approached Kane.

This time, its attitude was noticeably more respectful, not just because of itself, but because the few undead behind it also saw.

Facundo's attitude toward Kane was one of equality, akin to a partnership.

Being able to maintain a partnership with their master meant they were not entities to be challenged nor offended.

Maintaining respect was appropriate.

"My lord, now we will follow your command. You can call me Steel Bone."

Kane nodded and said, "Just call me Kane."

Then, Kane thought for a moment and asked, "May I ask, why do you still retain loyalty to Facundo, and are there more loyal factions?"

This was something Kane was curious about, and if there were more loyal factions, it would be a pity to accidentally wipe them out.

If it was possible to win them over, spending some time would be worth it.

"If you can't say, it's okay."

Upon hearing Kane's question, Steel Bone responded, "There's nothing to hide. The reason we remain loyal is that our souls retain a thirst for power."

"I don't know if my lord understands the undead; we who were transformed by Lord Facundo were not naturally born."

"We still retain the memories, strength, and habits from when we were alive, which means our power does not diminish much when we become undead."

As he spoke, Steel Bone extended his bony hand, clawing at the air forcefully, producing five cracks in the void.

"But there is a price to pay, which is that our strength can never surpass what we had when we were alive."

After hearing Steel Bone's simple explanation, Kane roughly understood.

Based on previous simple knowledge of the undead, combined with the current information,

it seems that the unnaturally born undead still remain as they were.

Compared to when they were once living, there would be some loss in their souls, and some issues might arise.

Mostly emotional or character changes.

Their strength might decrease, but not significantly.

Because becoming undead means their strength, no matter how strong, cannot surpass their former selves.

Endless life, yet strength cannot progress, this endless life may be a torment for those undead who desire power.

At such a level, becoming undead, they still retain the desire to rise.

And seeing Facundo's method just now, it seems he has the ability to enhance these undead, surpassing their former selves.

Which means that in the past, Facundo used this method to control so many undead with autonomous intelligence under his command?

Just heard Steel Bone continue to say, "There aren't many loyal faction undead, most are powerful ones. Excluding some who have died, there are only the four of us left."

"Why?"

Kane couldn't help but ask.

"Why are the loyal factions composed of powerful undead?"

Upon hearing Kane's question, Steel Bone, without any impatience, continued to explain, "Weak undead can absorb the souls and flesh of living things, or other simple means, allowing their strength to still have some growth. But this is ultimately limited."

"No matter how much they improve, they can never cross that final threshold."

"And we are before this gate, unable to cross, only Facundo has the capability."

The loyalty of these undead to Facundo was fundamentally tied to interests.

And only powerful undead could generate such interests.

And among the few undead in front of him, the weakest one ranked among the top few of all undead.

They could truly be called the strong.

"Then why are there so few, if that's the case, powerful undead should all be loyal to Facundo."

Steel Bone shook his head, "They set their hopes on Facundo's corpse, which is a true Divine Body. Acquiring that body could easily allow one to cross that threshold."

"It might even allow them to become a natural undead, or perhaps return to being a living being."

Kane understood this.

Those with great power, whether undead or otherwise, possess their own pride and dignity.

It seems they do not wish to continue submitting to Facundo's command, and now is a very good opportunity.

This corpse is the supreme treasure left for them.

For these undead, this treasure has a deadly allure.

"But now only the three in front are vying for this corpse."

"They all promised that acquiring the corpse and crossing over, they would establish an undead Empire, offering all undead a chance to rise, without controlling their freedom."

"For this, they even swore by their own souls."

"And we are at odds with those three."

Understood.

Hearing the description, Kane had almost a complete understanding of the entire undead influence.
