According to the explosion rate of 80%, that is, there are 400 Ability Cores in the bag!

400 Ability Cores! Not four, forty, but four hundred!!

According to the usual explosion rate, the explosion rate is 5%. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In other words, except for Mu Feng, if anyone else wants to obtain four hundred ability cores, they need to kill at least eight thousand level 3 zombies to have a chance to get them!

Mu Feng swallowed his saliva excitedly, 400 ability cores, according to the minimum standard of 10,000 source crystal coins for each one, then there are four million source crystal coins at the bottom!

Fierce, really fierce, it took less than an hour!

However, Mu Feng was not satisfied, and the killing continued.

However, in order to dare time, Mu Feng did not deliberately look for a third-level zombie to kill, and accelerated to the depths.

The more he walked into the depths of the Devil City, Mu Feng also put away his attitude and became serious.

He could clearly feel that in the depths of the Devil's City, there were several places where the aura was faintly moving, and the emitter of these breaths was none other than the corpse king-level mutant corpse - a fifth-level zombie!

Even Mu Feng felt that it was a little tricky, after all, he had to kill five fifth-level mutant corpses, and now that he thought about it, it was still a bit stressful.

The deeper you go, the more complex the terrain becomes, with some places open and others crowded to the point where no one can get through. The traces of the third-level zombies also began to slowly disappear.

In this area, most of them are fourth-level mutant corpses.

Kill a level 4 zombie and you'll burst out with two ability cores!

One core is the primary core, just like the Zombie Level 3 one, and the other is an advanced core.

Advanced Ability Core, which can be used by Level 4 Mutants, and the user must have a primary ability.

Because level 4 zombies are difficult to kill, the explosion rate is even lower. Therefore, the price of an advanced ability core is even more terrifying, one is at least above 100,000 source crystal coins!

However, it sells very well!

The fourth-level ability, in the Black Wind Desert, can be said to be the best, everywhere is a respected person, and he is also a reused talent in the territory, so it is generally not bad for money. But killing a level 4 zombie is still a risk for them, so many people will choose to buy it.

……

In order to make the most efficient use of the current manpower and material resources, Mu Feng planned to let them act separately.

The one-eyed dragon can take charge of himself, give him a bottle of spray, and kill the level 4 zombie alone.

The rest of the zombies are in groups of five, and they are given a bottle of spray, even if it is one person, they can kill the fourth-level zombies.

He himself carries a bottle of spray and kills zombies.

This way, you can get the most out of your ability cores.

The three squads have different routes and the same destination. Mu Feng set up to gather next to the nearest fifth-level zombie aura.

……

"The fourth-level zombie is really much more powerful than the third-level zombie, the vitality is to be strong, and it can last for five minutes." Mu Feng muttered silently.

For killing fourth-level zombies, Mu Feng was even more snack. Because he could clearly feel that he was about to break through to the third level and become the fourth level!

At level four, you can absorb Advanced Ability Cores and gain a second ability!

The choice of the second ability was very selective.

There are several cases, one is that the properties of matter are the same. For example, Albany, a fifth-level powerhouse, his first ability is to control silt, and his second skill is to control rocks, and the material attributes between the two are basically the same, and they can be converted to each other.

The second is ability amplification. For example, one ability is fire control and the second ability can be fireblast, both of which are fire-based abilities, and the user can combine the two abilities to create a new ability move. The Falling Fire Rock Explosion Technique, a well-known synthetic move, is the sixth-level powerhouse, Qin Fu's specialty.

The third is ability synergy. For example, Mu Feng's first ability is invisibility, which lays a foundation for him, focusing on one-hit kills. Suddenly appear and kill enemies in seconds. So, the second ability is better if it's a high-burst ability, like extreme violence. Crazy Blood, and other abilities that can provide Mu Feng with super high added value.

……

The process of killing the fourth-level zombies is quite easy, except for a few fourth-level zombies with tricky abilities, it takes a little effort, but it doesn't hurt. Mu Feng is happy to see this situation, the more powerful the ability, the more powerful the ability core that bursts out, the price will naturally be higher.

"Purple Light Half Moon Slash!"

Seeing a fourth-level zombie again, Mu Feng shot out a half-moon, unexpectedly, this fourth-level zombie actually dodged, shouted violently, and rushed directly towards Mu Feng.

Mu Feng was surprised in his heart, the speed was so fast! This is a level 4 zombie!?

However, he was not worried, although the speed was slightly faster than that of ordinary zombies, Mu Feng could still catch his movements, and was ready to predict that a purple light half-moon slash would take him down.

Look at the timing, another shot!

Unexpectedly, this mutant corpse actually screamed, his whole body, his muscles bulged, and he could feel that this zombie seemed to have turned into a vacuum cleaner, and the surrounding source force factors were frantically pouring into his body!

Mu Feng was startled, he saw that the light in this zombie's eyes was changing!

The light in its eyes turned from purple to a faint gold!

According to the mantra for identifying the level of zombies, one and two are empty, three are red, four are purple, and five are gold.

Golden! It's the mark of a level 5 zombie!

"Isn't it, this fourth-level mutant corpse suddenly turned into a fifth-level mutant corpse?" A big question mark popped up on Mu Feng's head. I couldn't help but think about it, and waved my arm violently.

Whew!

The purple light half-moon swept past the ground, and a huge ravine was cut out on the ground, and it still shot at this strange mutant corpse with undiminished power!

In just an instant, it seemed to have become a fifth-level mutant corpse, its agility was greatly improved, and it twisted its waist slightly, and Half Moon did not slash his body, but slashed it on its arm, and a large amount of blood flowed out!

The mutant corpse with golden eyes roared angrily, as if it had no effect at all, it was still stormy, attacking towards Mu Feng!

The speed was extremely fast, and in the blink of an eye, it was in front of Mu Feng!

This sister of yours is completely a fifth-level mutant corpse!

"Drink!"

This mutant corpse rushed to Mu Fen's location in an instant, and the hand with the blood mark grabbed it violently, but Mu Feng disappeared in place, and the source power on the claws fluctuated, and the rock pillar behind it was chopped into pieces at once!

When Mu Feng hurriedly used the stealth ability and flipped to the side, he thought that he would observe for a while to see what was going on with this zombie, and then make a judgment.

At the same time, the demon team that was scattered around to kill zombies separately was summoned back to assist him in killing.

First of all, it's certain that this mutant must have an acceleration ability.

The second ability is supposed to increase his strength violently, but this improvement is too exaggerated, and it actually pulls him up a level. It's definitely different from normal augmentations......

Mu Feng suddenly seemed to think of something, his eyes flashed with excitement, and he swallowed a mouthful of saliva.

Could it be that its second ability is one of the top 10 advanced abilities recorded in the history books...... Rank up?

It has been recorded that when this ability core came out, it was auctioned for the highest price in history, a sky-high price of one billion!

This great good thing was touched by me? (To be continued.) )
