Just like just now, the aura that he unconsciously released suppressed the spirit of fear so much that it couldn't move. What's the use of this?

The Spirits of Fear have no experience points, but they can improve themselves through soul energy like Sion and Robin Hood.

Looking at the skull thrown at it, the Spirit of Fear was extremely happy. It jumped up, bit the skull, and quickly absorbed the soul energy in it.

Li Ziyu has 100% control over the undead servants under his command, and their life and death are in his hands. He can feel that the spirit of fear has become stronger after absorbing the soul energy.

[Kill armed undead, experience +150]

For the second skull, Li Ziyu casually threw a King Kong, followed by a hedgehog, and finally a tortoise shell... He distributed the skulls one by one to the undead servants under his command, and experience value reminders popped up one after another.

The 13 undead provided Li Ziyu with a total of 2030 experience points. Li Ziyu casually consumed 1400 experience points to upgrade the Bone Spirit Boots to level 10.

[Bone Spirit Boots have been upgraded to level 1, Agility +1, Experience -50]

…

[Bone Spirit Boots have been upgraded to level 10, Agility +1, Experience -230]

Congratulations on upgrading your Bone Spirit Boots to level 10 and gaining the skill "Strength Amplification (Aura)"

[Strength Amplification (Aura): Can increase the strength of undead servants within a certain range.]

The two skills granted by the Bone Spirit Boots are both group amplification aura skills. They do not improve Li Ziyu's personal combat power much, but they greatly improve the undead servants under his command.

"I wasn't hunted down in vain. The Soul Chou Battlefield is such a great place. If there weren't such a place, how could I have improved so quickly?"

Li Ziyu sighed sincerely.

After absorbing another 13 skulls, the auras of Sean and Robin Hood became stronger. Li Ziyu had a vague feeling that they had reached the critical point of breakthrough. With a few more skulls, Sean and Robin Hood should also break through and become second-level professional undead.

After receiving a large amount of soul energy replenishment, Sean and Robin Hood were a little dazed. Li Ziyu knew that they had obtained the undead inheritance from the soul fire and were absorbing it at this time.

It's not just Sean and Robin Hood, but also the Spirit of Fear and King Kong.

The hedgehog and the tortoise shell seem to have not been inherited and are still the same as before, but their bones have evolved a lot. The bone spurs on the hedgehog are harder and more ferocious, while the tortoise shell has grown more hyperplastic bone plates, and its defense has been improved.

After waiting for a while, Sean and the others gradually woke up, their soul fires returned to their lively state, and the undead inheritance was absorbed by them.

Thinking of the inheritance of the undead, Li Ziyu felt a little depressed. Why can Sean and others obtain the inheritance of the undead, but I rarely get the inheritance?

Is my intelligence very low?

I will never admit this!

But there is no inheritance, there is no inheritance. Li Ziyu still envies Sean and the others.

From the past, the higher the intelligence of the undead, the more likely they are to obtain the undead inheritance. Among the team, the hedgehog and the tortoise are the two undead who are really stupid and cute, and not very intelligent, so they have almost no special undead inheritance. This time, even though they absorbed so much soul energy, they were unable to obtain the inheritance.

Li Ziyu couldn't get it, so she could only blame it on the fact that she had a system.

After the undead in the team had recovered, Li Ziyu waved his hand and said, "Let's go back and go hunting!"

He is now full of confidence. Not to mention that he has been promoted to the second level, even if he has 20 more undead under his command, he dares to go and do another job. The worst that can happen is that he will be hunted down again. It's not a big problem!

Sean and King Kong were immediately eager to try, and the team set off and returned to the battlefield.
