Although the necromancer knew that Liu Suifeng had just been upgraded to level 15, what he didn't know was what skill Liu Suifeng unlocked at level 15.

And Liu Suifeng's level 15 unlocked skill is also a very powerful skill.

That's refraction!

It's the same as he literally means.

It is a skill that can attach a state to yourself, refracting the light around you, but temporarily entering a hidden state.

And this skill can not only enter the stealth state, but also provide a certain number of attack blocks.

Also 5 times in time.

After Liu Suifeng launches a refraction and enters the hidden state, it is the 5 attacks that he receives after completely blocking.

No matter what kind of attack it is, it can be completely blocked.

That is to say, within those 5 attacks, no matter how powerful the opponent's attack is, it can be blocked, that is to say, within those 5 attacks, Liu Suifeng is temporarily invincible.

However, although this skill seems to be buggy, in reality, it is not as powerful as I imagined.

After all, in addition to the boss's attack accident, there are also a lot of mobs from time to time.

These five more blocks are also not selective, and all attacks received are automatically blocked.

So whether it's the mob's attack or the boss's deadly attack, it's automatically blocked.

So in many cases, the number of times of each level of these five layers, when the boss has not had time to attack, will have been consumed by the mobs.

And many of the boss's attacks will not be a single one, they will be multi-stage attacks.

For example, this necromancer's necromantic wave is a two-stage attack.

And which super giant zombie before, every time he punches, it is a multi-stage attack.

After all, the fist is too big and the movement is relatively slow, so it is designed to produce multiple damage with one attack.

Such a multi-stage damage is also incomparably bloody for Liu Suifeng's refractive skill.

But fortunately, the current necromancer's necromantic wave attack is only two, otherwise Liu Suifeng, who was hit head-on, might still really be killed.

And this hidden state of the refractive skill does not exist all the time, but is like a psychosis, which is intermittent.

That is, to be invisible, then to be visible, and then to be invisible.

It's not stealth all the time.

So that's where the player's control comes in, and that's where the difference between stealth and revok is revealed.

Move when you're invisible, so you can't see when you're visible, and then you're moving when you're invisible.

And in the previous short invisibility, Liu Suifeng was not wasted.

Directly moved quickly to get close to the two necromantic dragons, and then directly killed them.

If there is no cover of this stealth, I am afraid that I will have to kill these two necromantic dragons, but it will still be a simple effort.

Moreover, in the presence of the necromancer, if he fought with two necromantic dragons, the necromancer would definitely not let go of this opportunity to attack him.

Maybe by then, slow will really be over.

Therefore, Liu Suifeng took this opportunity to quickly kill these two necromantic dragons first, not the necromancer.

After all, the blood of the necromancer is thicker than that of these two necromantic dragons, and if they can't die, they will be in trouble, so they will be besieged collectively again.

And these two necromantic dragons, Liu Suifeng is sure to kill them with one move.

Of course, this is also thanks to this new unlocked skill at level 15.

This skill is a bit powerful, after all, it is a level 15 skill.

Not only can you be stealthy and block attacks, but you can even add the attack power of normal attacks.

If it weren't for the additional attack power of the skill, Liu Suifeng would really not be able to kill these two necromantic dragons in one move.

Now that one move is killed, there is nothing to drag on the water, and I really have to thank this level 15 skill.

"What! how is this possible!"

The necromancer couldn't believe it was happening.

Unexpectedly, Liu Suifeng did not die.

And it still seems that he has mastered some new skill, and then he killed his two necromantic dragons with one or two swords.

Now it seems like it's about to get him.

"Necromantic Wave!"

Once again, the necromancer struck.

"I can hide from the first day of junior high school! I can't hide from the fifteenth!

But this time, the cooling of Liu Suifeng's flickering dagger was already complete.

And in ten seconds, that is, two five seconds, Liu Suifeng's skill charge will also be completed.

And the final blow of this refraction, Liu Suifeng didn't use it.

A total of five times, two times to block the necromancer's necromantic wave, one knife was used to kill the first necromantic dragon, and the second knife was used to kill the second necromantic dragon.

Now there is only one attack or number of times left to block damage.

This time, it was clear that Liu Suifeng was not going to use it to block attacks.

It's going to be used on offense!

Crash!

Liu Suifeng caught the dagger and flashed, and directly came to the necromancer.

Of course, which necromancer wave of the previous necromancer is, of course, already empty.

Click!

Slash it with a knife.

This time, it is really a knife of destiny, in the case of so many things on vacation, Liu Suifeng's luck is also good, and a knife is a critical hit.

"Goo-whoa!"

The necromancer also let out a wail, and it was directly annihilated into ashes.

And those dead mobs can't be resurrected as infinitely as before.

At this time, Tang Wan'er and the others, who were almost at the limit, were finally saved.

Level 2!

This time, in this time of preparing for the third level, Liu Suifeng was no longer as jerky as before.

All of a sudden, I sorted out the equipment and all the items, and then I hurried into the practice room to farm monsters and upgrade.

Of course, while they were farming monsters, they were not idle, and they were also watching the content in the previous social section.

This time, after the second level, a large number of people were reduced again.

There were more than 9,000 rooms left alive before, but now, after the second level, there are more than 5,000 rooms left.

That is, the number of survivors has decreased from more than 900,000 to more than 500,000 at once.

One level has wiped out more than 400,000 people, which is indeed a frightening thing.

After all, no one knows that after the next level, sometimes there will be poisonous people alive.

However, in this social section, it is not all this kind of bad news.

People also began to exchange previous experience and strategies through this social section.

Liu Suifeng and they also know it when they see it, as if other people's methods of clearing the customs seem to be different from them.
