Li Ziyu took a deep breath and retrieved the instructions for the dark skeleton from the system.

Dark Skeleton

[Introduction: Very dangerous undead. Be careful when using them. Dark Skeletons don't care if they are friendly or not. As they absorb more dark energy, they will become more powerful. They are monsters that can evolve.]

[Requirements: Demonized Skeleton*1 unit, Mutated Soul Energy*30 units, Soul Energy*500 units]

After reading it carefully, he understood everything. He had been wondering why this undead needed so much soul energy. Now he understood everything. 500 units of soul energy. Until now, among all the skeleton undead units of Li Ziyu, there was no unit that required such high soul energy.

Such a large amount of soul energy determines that his growth rate and intelligence level are not comparable to those of the stupid skeleton undead.

As the royal family among the alien undead, the Violent Skeletons and the Dark Skeletons are born with the ability to control and dominate the lower-level undead. Not to mention the skeleton beasts, they can even suppress the bull demons and make those guys obedient.

It looks small and no different from a normal skeleton undead, but it is actually a guy pretending to be a pig to eat the tiger.

Li Ziyu looked at the dark skeleton silently. This guy... has been by his side for quite some time. He has been hiding very deeply and has not been exposed at all.

The dark skeleton, who was originally watching the fun, was obviously stunned when he saw Li Ziyu suddenly looking at him. Then he seemed to read something in Li Ziyu's eyes, and immediately pretended to be confused, scratching his bald skull, looking stupid.

Li Ziyu narrowed his eyes and said in a bad tone, "Great, that's amazing. You really look like a high-level undead. I underestimated you before."

Dark Skeleton: (｀Д)!!

Violent Skeleton: ⊙(◇)?

"Keep pretending, I want to see how long you can keep pretending." Li Ziyu said unhappily as he looked at the shocked look of the dark skeleton.

The soul fire in the dark skeleton's eye sockets slowly moved and floated to the side, just like when a person is embarrassed and dares not look directly at someone and avoids looking.

"Boss, what happened?" Liu Xingxing and Zhang Peng were watching in confusion. They didn't know what exactly happened. When they came, they saw a strange-looking undead fighting with a skeleton beast.

"Tsk, what happened? Haha, you may not believe it when I tell you, but this guy is not simple, not an ordinary undead. He is very smart and has been hiding beside me. In fact, his intelligence is probably not lower than ours." Li Ziyu pointed at the dark undead and said to Liu Xingxing and Zhang Peng.

After hearing this, the two couldn't help but look at the dark undead in surprise. Is this guy so intelligent? They can't tell. Apart from the different colors of his bones and soul fire, and some skills, it seems that there is no big difference between him and other skeleton undead. At best, he is just a much stronger skeleton undead.

But what does it matter whether you are smart or not?

"But I feel that my cat man is also very smart. Sometimes he is smarter than me." Liu Xingxing scratched his head and asked in confusion.

"It's different. Every one of the undead under the boss is simple-minded and very obedient. Are your cat people as obedient as the undead?" Zhang Peng stared at the dark skeleton, but explained to Liu Xingxing.

Liu Xingxing thought about it and seemed to suddenly understand.

In fact, it is easy to understand. The silly undead are easy to control and have infinite loyalty. They are simply one of the best races. Whether it is the mole people or the treasure-hunting cat people, they all have their own ideas and have loyalty limits that fluctuate. They can never act 100% according to the city lord's wishes like the undead.

The best evidence is that Li Ziyu ordered the skeleton undead to die. These guys did not have any other ideas. They would honestly line up to die and allow the enemy to kill them, just because of Li Ziyu's order. The races under Zhang Peng and Liu Xingxing would never do that.

Not to mention whether too many deaths would lead to rebellion due to low loyalty, even if more people died, the races under their command would be defeated and they might even flee.

Among the time travelers, there are definitely not many who can possess a race like the undead.

But now, the undead in front of him actually has intelligence no less than that of humans, and is no longer stupid. It is hard to say whether he will be as obedient as the skeleton undead. This is a variable.

Normally, you can't see anything wrong with it. It's all good for everyone, but at the critical moment, it can be fatal. For example, if you ask them to cover your retreat and they run away, the enemy will chase them directly. Isn't that dangerous?

Knowing that he had been completely seen through, the Dark Skeleton simply stopped pretending and straightened his back, with an expression that said, "No more pretending, let's get straight to the point, I'm the master, what do you want to do to me?"

Seeing this, Li Ziyu stroked his chin and said slowly, "I'm wondering if you still completely obey my orders. How about we do an experiment?"

The dark skeleton soul fire flashed twice, and there was a bad premonition.

"You, self-destruct your soul fire." Li Ziyu suddenly turned his head to look at a skeleton undead and gave the order.

The skeleton undead turned its head to look at Li Ziyu, and then without hesitation, the soul fire made a very slight "puff" sound, and the soul fire in the skull dissipated, turning into a pile of bones scattered on the ground.

Li Ziyu nodded. Sure enough, this was the absolutely loyal Skeleton Undead. Even when he asked him to self-destruct, he completed the order without hesitation. He turned to look at the Dark Skeleton and grinned, "What's next, you?"
