12.5 billion territory energy, which can be used to complete the transformation of 100 seventh-order undead, must be enough, even if these 100 undead are all seventh-order excellent level, there will be 2.5 billion left.

But there is a problem that there are not enough corpses on Karen's current side of the territory.

The 20 corpses on the side of the Mystic Society and Garo, plus the 42 corpses that Karen herself got in the ruins, and the 12 corpses that the territory originally had, are still 26 corpses.

But these are all minor problems, and they can't bother Karen.

No, he could still go to the Mystic Society or have Garo's City of Chaos bring some corpses.

But Karen didn't do that, he chose a more foolish approach.

This guy separated the seventh-order outstanding corpses in his hands, one corpse was divided into two parts, and then fused with the sixth-order outstanding corpses respectively.

Using this method, Karen spent less than 500 million territorial energy to easily gather 100 seventh-order corpses, and all of these hundred corpses were of the seventh-order ordinary level.

Obviously, Karen played this hand to save territory energy, and as a result, he did save a lot of territory energy.

It took 500 million to gather 100 ordinary corpses of the seventh order, and then spent another 2.5 billion to transform all these 100 corpses of the seventh order into undead, and it only took 3 billion territory energy in total, and Karen completed the standard of the graveyard upgrade.

The reason why he was so slamming was that he knew very well that the ordinary Seventh Order was actually of little use in front of a truly strong person.

This is best proved by the previous battle between Feng Kui and the Iron Hammer Society.

An eighth-order excellence-level powerhouse can easily kill more than a dozen seventh-order powerhouses with a single move.

Therefore, Karen feels that it is not necessary to spend energy to transform those seventh-order elites or seventh-order outstanding existences, it is not worth it, it is better to use the lowest energy to meet the conditions for territory upgrades, and then concentrate resources to cultivate those potential undead, and it is more reliable to upgrade the territory.

However, even so, Karen's territory has also increased in strength due to the transformation of these 100 seventh-order ordinary undead, and at the same time, the conditions for upgrading the territory to the eighth order have also been unlocked.

[Ding, you have completed the [Graveyard of the Dead] upgrade conditions, and the territory upgrade conditions are unlocked!] 】

【Territory upgrade conditions:

1. The number of undead under your command has reached 3 million!

2. The strength of the seventh-order legendary-level undead under his command has reached 5!

3. Have 5 billion territorial energy! 】

Seeing these three conditions, Karen didn't know what expression to show.

It's not that these three conditions are difficult, on the contrary, these three conditions are not difficult for Karen now.

Now that Karen has completed the third one, the second one is easy.

Now there are 2 seventh-order legendary-level undead under Karen's command, including him, and there is one Alice who can be upgraded as long as there is something to gnaw.

As well as the little green with the power of sacrifice, the beast protector Krein, despair, madness, and other undead with great potential.

In addition, Karen still has two inheritances from the ruins, as well as several legendary quality magic stones, as long as Karen is willing to spend blood, in less than a month, Karen will be able to cultivate a group of seventh-order legendary-level subordinates.

This is also one of the fundamental reasons why Karen will not care about the strength of her transformed undead.

So the second condition is not a problem for Karen, it is the first condition that is really a problem.

Or it should be said that what Karen really can't understand is the first condition.

He didn't know why the system wanted to use the number of undead under his command as a condition for territory upgrading, judging from the current situation, the sea of undead was really not much use, not to mention the position, and the combat effectiveness was not good.

While it doesn't take much energy to transform, it takes a lot of turf and energy to feed them.

If it weren't for the need to upgrade, Karen was even ready to cut the undead under her command to less than 100,000 at this time, so as not to cause unnecessary trouble because the undead army under her command was too large.

"Forget it, it's the boss, it has the final say, 3 million undead are 3 million undead!"

In the end, Karen still bowed to the system boss.

However, he didn't get the matter of 3 million undead right away, anyway, he now has corpses and energy, and he can solve this problem with a wave of his hand, there is no need to rush for a while, or wait for condition two to be completed.

Then, Karen closed the attribute page, and at the same time found several undead under her command who were ready to be cultivated with all their might.

Except for Alice, Midori, Madness, and Despair.

There are also Song One, Caesar, Crein, Dust Corpse Witch, Soul Seeker, and Deathwing.

The first four of them are really talented, and of the latter ones, three of them are obviously forcibly cultivated by Karen who guards the calf, especially the Soul Explorer and Deathwing.

The strength of these two is not at all the seventh order, but Karen, a calf protector, is to cultivate them, they are less than the seventh order, and Karen fused a seventh-order outstanding corpse to him, and spent 300 million before and after, and forcibly turned them into seventh-order undead.

When spending money for these two subordinates, Karen didn't have a little bit of the previous careful calculation, which is called a cost-free.

However, in Karen's situation of no matter the cost, the strength and potential of the Soul Explorer and Deathwing have been greatly improved, and the two undead are even luckier that they are very compatible with the inheritance that Karen brought out from the ruins.

When Karen's two inheritances were handed to them, the two undead entered the state of inheritance one after another.

Looking at their posture, after receiving the inheritance, their strength can at least be improved to the seventh-order excellence, and it shouldn't be very difficult for the seventh-order legend to work a little hard, which is quite a big surprise for Karen.

However, the situation made Xiao Lu on the side very unhappy, and this kid didn't know where he got so much jealousy.

As soon as Alice came over, Karen handed her a mountain-like magic prop as a snack, and gave it to the Soul Explorer and the Deathwing Inheritance respectively, but she didn't give him anything, and the little guy was unhappy, and he didn't know who he learned it from, so he ran to Karen and hugged Karen's thigh and didn't get up, so he had to ask Karen to give him something, and in the end Karen was really entangled by him, so he could only take out the magic stone that he had absorbed part of the [Legendary Quality] to him.

Xiao Lu, who got the magic stone, was immediately happy, holding the magic stone everywhere to find the undead on the side to show off.

Desperate crazy women they are okay, they don't care about Xiao Lu, of course, they can't beat Xiao Lu and don't dare to do anything, just pretend that they didn't see it, Alice is not so polite, Xiao Lu showed off in front of her, this girl grabbed it directly and took a bite......
