The Lich King, the Ghoul King, the Wraith King, and the Skull King, the strength and territorial scope of the 'Four Kings' are not far apart, and the 'Four Kings' have also fought with each other, but in the end, no one can help anyone, so after thousands of years, they gradually maintain a relatively balanced situation with each other.

Uther's current cultivation strength has reached the third level and the ninth order, and basically there is not much hope for making a breakthrough on the basis of this realm, because the next realm of the third level and ninth order is to truly condense the rudimentary form of the law into the truth, refine it into the self origin, and thus promote to become a powerhouse of the true god realm.

This step of breakthrough can be described as a thousand difficulties, and it is no longer possible to break through by relying only on resources, but also needs the support of qualifications, understanding, chance, and personality, all of which are indispensable!

For Uther, they can no longer rely on devouring other undead to grow, and the only thing that can help them improve their cultivation strength is the fragments of personal authority represented by the fragments of the Necronomicon and some super rare treasures or opportunities that can improve the cultivator's understanding of the concept of law.

However, because of the balance and containment of each other, no one among the 'four kings' can dominate the world, and each of them has developed to a bottleneck stage in terms of cultivation strength and territory, and it is impossible to easily attack other undead lords to expand their territory. Because whoever wants to expand, it will inevitably touch the interests of other members of the 'Four Kings', causing the other party to intervene.

It is precisely because of this situation that the other undead lords under the 'Four Kings' will be given the opportunity to develop and grow. In a way, the 'Four Kings' can also be seen as the backers of these undead lords.

If any undead lord is threatened by one of the 'Four Kings', it can choose to seek refuge under the command of the 'king' corresponding to the faction of its undead race.

But this kind of protection is not without a price, at least it requires the surrender of the undead lord to the 'king' he has sought refuge. Otherwise, the 'King' would not have been so kind to protect them for no reason, and might even have turned his hand on them for wanting to seize the fragments of the Necronomicon.

Of course, this kind of behavior of the undead lord taking the initiative to seek refuge in something more powerful than it often comes with some corresponding costs and rewards. For example, after a lord in the lower rank has sworn allegiance and entrusted the fragment, the king in the upper rank must also take an oath to grant the courtier the protection he deserves in the name of the lord.

In this case, the oath between the undead lords is not a verbal joke, but has a substantive enforcement effect. Because this oath is an oath engraved on the pages of the Necronomicon, and the pages of the Necronomicon are bound to the origin of its holder, a violation of the oath is tantamount to a self-severance, and the consequences cannot be ignored.

Of course, the 'Four Kings' provide 'protection' to the lower-ranking lords, and the lords need to pay the 'Four Kings' loyalty to fulfill their obligations as courtiers, which is called 'tribute'.

The form of 'tribute' between the undead lords is actually to provide a sufficiently high-quality Death Origin power to be offered as food for the Four Kings to enjoy.

The so-called power of the origin of death here is actually a kind of essence that the undead lords personally spent a lot of effort to condense the death energy and purify and refine it, which is the essence of the purest high-quality death energy.

This kind of death origin power, which has been purified and refined by the undead lords, can be called a rare great supplement even for a powerhouse of the 'Four Kings' level like Uther. After absorbing and refining, it can be used to improve one's own cultivation, and the more the better.

The 'Four Kings' let the lords under their command, who were courtiers, condense this power of the origin of death for themselves, and regularly harvest the fruits of the lords' labor into their own hands in the name of collecting tribute, which is equivalent to helping themselves cultivate at the cost of the hard work of other undead lords.

With such a benefit, they will resist the idea of snatching the remnants of the Necronomicon from the courtiers and lords under their command.

After nearly 10,000 years of development, all the lords in the undead realm who can count the names have formed a deep or shallow vassal relationship with one of the 'Four Kings', although this vassal relationship does not make the lords become slaves of the 'Four Kings', but the common interests of the faction to which they belong are also real.

Except for those newcomers who have just grown up and have not yet accumulated any fame, few undead lords can be free from this factional interest network of the 'Four Kings', because the 'Four Kings' will have a tacit understanding to jointly suppress this kind of lone faction.

After all, if you want to be a lone faction, it means that you are not protected by any of the 'Four Kings', and there is no backer behind it, so if any of the 'Four Kings' wants to attack them, you don't need to worry about anything.

Now, Uther's request to Barrick and other undead lords is tantamount to breaking the tacit agreement that has been maintained between the 'Four Kings' for many years.

"Hmph...... Hahaha......" Seeing Barrick's somewhat ugly face, Uther suddenly laughed wantonly.

After laughing for a long time, it gradually stopped laughing, and then looked sarcastically at the zombie lord at the bottom of the steps, and the undead lords behind it with the same resentment on their faces.

"Really, I can't help but laugh a little...... Barrick, don't try to measure our thoughts with your shallow wisdom. Do you really think that what I asked for was just a decision I made on my own?!"

Hearing this, the lords under the throne steps were stunned for a moment, and then their faces couldn't help but change greatly.

Barrick couldn't help but ask, "Your Excellency, what do you mean by that?"

"Don't you understand?" Uther stared at them.

The Lich King remembered what he had heard from another group of outsiders not long ago, about the pattern and truth about this Ethereal Tomb, about this Ethereal Relic Realm, and about the outer world of the Spirit Child.

On its dry face, a hideous color gradually appeared: "Everyone, times have changed!"
