Karen wants to improve her strength, there are two main ways, the first is to rely on the feedback of the territory and self-cultivation.

This method, in fact, has reached a rather terrifying speed after the territory level 4.

Not to mention anything else, the territory can provide him with 500 personal energy every day, and the [Tower of Bones] can also provide 2,400 personal energy, plus his personal cultivation is actually only a few months, Karen can cultivate his strength to the 4th order excellence.

But at this speed, Karen still felt that it was slow, so at this time he only used another method.

And Karen's so-called other method, that is, of course, killing.

Killing is still the fastest way for Karen to grow, especially when he kills himself, so that he can get the most complete personal energy.

Therefore, when Karen needs to quickly improve her strength, Karen's first thought is this way, and Karen searches for the object she can do.

At this time, the lake of fish-people came into Karen's field of vision.

During this time, Karen also knew more or less about the Lake of Fish-People, and Karen also knew a little about the situation of the Lake of Fish-People.

The Lake of the Fish-People is southwest of the Land of the Dead, and although it is called a lake, it is actually not much smaller than the sea.

In the middle of the huge lake, there are islands one after another, and on the islands there are a large number of fishmen living in tribes.

The living conditions of the fish-people are somewhat similar to that of goblins, they do not have a brilliant civilization, and are still in a very primitive state.

Through fishing, self-sufficiency, there seems to be little communication between tribes, and life is calm and serene.

Of course, when they were targeted by Karen, the so-called peace and serenity were far away from them.

Karen has never been a good person, and in order to be able to quickly improve her strength, this one reason is enough for Karen to raise the butcher knife.

On the first day he saw Silverlight, he had already asked Deathwing to conduct a brief exploration of the Lake of Fish-People, and then locked on to a target based on the message from Deathwing.

I have to say that the strength of the fishmen is much stronger than that of the goblins, although Karen tries to choose a weaker tribe, but the strength of the tribe selected in the end is not weak.

There are almost 5,000 people in the entire tribe, all of whom are above the 1st order, 40% of the people have reached the 2nd order, and even the third order has about 100 people, among which there are even 3 fourth-order existences.

It was precisely because of understanding the strength of that mermaid tribe that Karen understood why the lake of the fish-people was close to the Silver Hand and the Bourbon Kingdom, and the living conditions were still so primitive, and those two kingdoms had no idea about them.

In fact, it's not that they don't have ideas, but they can't move people's homes, just one tribe is so terrifying, and the combined strength of the entire Fish-Man Lake can be imagined.

If you really want to anger people, it's not certain who will hit whom.

However, Karen didn't have this scruple on his side, and Karen, who was anxious to improve his strength after locking on the target, immediately dispatched.

However, Karen didn't bring too many undead this time, except for himself, he brought Little Green, Deathwing, Erha, and Nether Leopard.

It's not that Karen doesn't want to send more troops, it's really not much of a need.

There are more troops, and there will be more people with experience at that time, which is not conducive to Karen's strength.

What's more important is that when there are more troops, Karen's traces will not be easy to deal with, and Karen doesn't want to expose the things that happened to the [Lake of Fish and People].

After all, he had just finished talking with the two kingdoms on his side, and he had just suffered a little loss and immediately raised troops to kill people, so as long as he was not a fool, he could see that he was tired.

Therefore, Karen finally took the four undead and went to the [Fish-Man Lake] to start the operation.

Karen's actions this time were particularly low-key, carefully groping, and it took more than a day to come to the island where the target was.

And after arriving, Karen and his party did not immediately take action.

One person and four undead, it first took two days to thoroughly understand the terrain of this island of tens of square kilometers, and then Karen took the undead to carry out the operation.

Karen didn't dare to directly attack or use fire to solve it this time like she did against the goblin tribe, in fact, Karen was ready to fight for a long time.

When they launched their actions, they were actually just secretly attacking the lone fishmen.

On the first day of the operation, Karen took advantage of the intelligence controlled by Deathwing, and led Midori to assassinate dozens of lone mermaids.

In order to upgrade, it was basically Karen's hand, but the corpse Karen was handed over to Xiao Midori, so that it sacrificed the mermaid's heart to improve its strength.

The harvest on the first day was not very good, and neither Karen nor Midori's improvement was high.

But this is just the beginning, it is only Karen's first round of temptation, after the first round of temptation to determine that she can eat the fishman, Karen and the undead launched a crazy slaughter operation.

Every day and night, he frantically kills the mermaids of the mermaid tribe.

At first, Karen and the others only shot at the lone mermaid, but on the third day, as Karen continued to fight, the fish-man tribe began to hold together, and Karen and they also began to attack the fish-man tribe.

Of course, with the five of them alone, they can't take a single fish-man tribe at all.

Even if this fish-man tribe has been slaughtered by them frantically in the past few days, and the number has been sharply reduced by two thousand, it is still impossible for Karen and them to take down the fish-man tribe.

Their impact, in fact, can only be said to be harassment strictly speaking, taking the opportunity to rush over to kill a wave and then turn around and run.

It's a very cumbersome tactic, but it's quite effective.

Relying on this tactic, Karen has destroyed a thousand mermaids, and at this time, the strength of both Karen and the undead under his command has been greatly improved.

And on the side of the fish-man tribe, after being slaughtered like Karen and them, their morale finally began to completely collapse.

The fishmen who were originally in a group began to scatter and flee frantically.

Their collapse made Karen and her party completely unscrupulous, and the final killing was staged in the collapse of the fish-man.

In the end, it took Karen 7 days to take 4 undead under her command to completely destroy this tribe of 5,000 fishmen.

[Ding, if you kill [Mermaid Boss] (Fourth-Order Boutique), you will gain 5000 personal energy, 3000 territorial energy, and your personal experience points will be full!] 】

With this system prompt sounding, Karen's operation in Fish-Man Lake this time is completely over.

Karen and a few undead under her command simply cleaned up the battlefield and left directly......
