After Xiao Green transformed into an undead, the power it held seemed to have increased a lot.

Under the sacrifice of 300 hearts, Xiao Lu's strength soared to [Second-Order Excellence], and the experience points were still full.

Obviously, if it weren't for the fact that Karen's territory level was only 2nd order, and Xiao Midori and these undead could not break through the third order, Xiao Green would have been able to directly advance to the third order in this wave.

However, Xiao Green's improvement is not unlimited, although the strength of the sacrifice of 300 hearts has soared directly to the edge of the 3rd order, but the sacrifice ability has also entered a cooldown period of up to 3 months, and it seems that it should be sacrificed too much in one go.

But no matter what, Midori's progress this time still didn't disappoint Karen.

And Karen found that it was not only Xiao Midori whose strength had improved after this battle, but also that the strength of many undead had also soared.

Among them, the biggest improvement was not the nine undead who took down the mine cave with Midori and withstood the goblin attack, but the two goblin skeleton mages who followed Karen almost without much strength.

Anyway, these two goblin skeleton mages have picked up a bargain.

Since the flames that burned the goblin tribes were provided by them, the experience of the burned goblins was counted on their heads, allowing them to soar directly from [second-order garbage] to [second-order elite].

That's not all, their original level 1 Nether Fireball was upgraded to level 3 after this battle, and they also comprehended new spells, so their strength should have improved a lot.

Of course, in addition to them, there are also some undead whose strength has also improved, especially those of the first and 0th order, and the improvement is not small.

However, Karen did not set his sights on other undead who had improved at this time, mainly because Karen had swelled.

After this battle, Karen held more than 10,000 territorial energy in his hands, and when he turned around, his territory must have spewed out a large number of second-order undead.

In this case, Karen didn't care too much about those first-order 0-order, and after this battle, Karen was already going to give up those 0-order undead.

After admiring Xiao Lu's attributes, Karen easily raised her level.

As Karen's heart gushed out with the power that Karen was already familiar with, ten minutes later, Karen's strength also jumped from [First-Order Excellence] to [Second-Order Garbage] and directly increased to the level of [Second-Order Ordinary]!

"It's a very good improvement, the strength is much stronger than before, and now I may still not be Old Jack's opponent, but I should be able to fight with the masked woman of the [Second Order Elite]."

After roughly estimating his strength, a satisfied smile appeared on the corner of Karen's mouth.

Of course, Karen was not immersed in the harvest and the improvement of her own strength, and soon began to get busy again, summoning Xiao Lu, who had just finished advancing, and those second-order undead.

Although Karen has already wiped out the goblin tribe, Karen is still very vigilant about the mine in front of her.

On the one hand, Midori's original power came from this mine, and the other thing is that Karen knew that this mine contained the corpses of goblin leaders and prophets from all over the ages, and she was worried that it would mutate and appear undead like in the goblin graveyard before.

Although she covets the power that made Little Green, Karen's mind is only on the corpses of the leaders of the Goblins in this current mine.

As for the strange power that Midori wields, he doesn't have any ideas to explore at the moment.

On the one hand, it was a matter of time, although the masked woman would not pay much attention to Karen's affairs, but if he did not appear in Dorai Village for a long time, Ogolen would also be suspicious.

Another point is that the power that Xiao Lu has is a little evil.

With the help of that force, Xiao Lu easily asked for the third order, and for such a power, Karen felt that it was better to stay away with her current strength.

Anyway, the mine is here, if that force is really still in this mine, Karen will have time to explore in the future, he has gained enough today, there is no need to risk it again.

There is a sentence that cultivates immortals that is particularly good, when you are walking on thin ice, you are brave and diligent, Karen is almost this mentality now!

He knows sensibly what he should do and what he shouldn't do.

…………

With a few second-order undead under his command, Karen quickly found the location of the secret room according to the location of the goblin leader.

When she arrived at the secret room, the cautious Karen did not go in first, but first sent a second-order undead to test the water, mainly worried about traps or undead or something.

The luck of that second-order undead was good, there were no traps in that secret room, and the corpses of those goblin leaders were not undead, which saved Karen a lot of things.

Karen entered the secret room after making sure that it was safe, and there were about 17 corpses in the secret room, and the quality was basically second-order, most of the quality was between [second-order ordinary] and [second-order elite], only two Karen couldn't see the information, it should be above the second order.

And in addition to these dozen or so corpses, there are also a lot of things in this secret room.

Karen took a general look and found that there were ores, weapons, and a mess of armor, and many of the materials looked like they should be human materials, which should be the goblin tribe's invasion of the human realm, or the loot obtained by killing the strayed humans.

However, the age of these trophies is mostly a long time ago, and Karen took a cursory look and found that the weapons and armor in them were basically scrapped, but there were many gold and silver coins still shining.

Karen hesitated slightly, and directly asked Midori and them to carry the pile of things back.

Although most of those weapons are gone, it's better than nothing, and the undead under Karen's command are still empty-handed, so bring them back and arm them to fill the scene.

As for those corpses, Karen directly took a [corpse manipulation] traction and led them directly out of the mine.

Then Karen simply cleaned up and returned to the territory with the undead under her command and all the second-order corpses obtained this time.

However, on the undead side, Karen didn't bring all of them back, but left all those Tier 0 undead behind.

There is no way, the family is poor, and these nearly 100 level 0 undead, Karen has to spend thousands of territories of energy a month to feed, so she has no choice but to give up.

It's just that what Karen didn't know was that when the sky was slightly bright, this group of undead all went into the mine in one go......
