Chen Feng's Demon Slaying Knife Technique can mobilize 80% of the source power, and under the full burst, his effective attack strength can also exceed two million, and when he hits the vital point, he can also kill the fourth-grade third-order abyssal beast in seconds, but it is definitely not as easy as Zhao Mei.

So just watching a battle made Chen Feng realize in what direction he should work towards.

Improving combat power through the domain is only one way, and outside the domain, there is also source power and powerful combat skills.

When Chen Feng entered the xenomorph world, he entered a misunderstanding, that is, he often relied on the strength of the powerful domain power to suppress the enemy, and then relied on the powerful explosion to solve the battle after taking the advantage.

This method is suitable for dealing with enemies who are weaker than Chen Feng, but if he encounters an enemy who is stronger than Chen Feng, Chen Feng has no choice.

For example, Zhao Mei.

Although Chen Feng's domain power strength has an absolute advantage, Zhao Mei's full strength to explode the source power can effectively offset the suppression of the domain power, and with her powerful combat skills, she can also suppress Chen Feng in turn.

So Chen Feng now has to think about how to fight when his domain is not dominant.

Fast speed alone is no longer enough.

Or a lot of observations of Zhao Mei's battles, which can bring him some inspiration.

After the battle, Zhao Mei piled up the corpses of more than twenty Earth Abyss Beasts, searched briefly, found a few pieces of Four-Rank Source Stone Ore, and then left quickly.

The battle just now would inevitably attract the attention of nearby Abyss Beasts or Abyss Demons, so every time the battle ended, she would leave the battlefield as soon as possible to avoid trouble coming to the door.

Chen Feng cautiously followed, he had now become interested in Zhao Mei.

Zhao Mei didn't know that she was being tracked, and returned to her foothold as usual.

Chen Feng followed Zhao Mei all the way and came to a forest, and after Zhao Mei entered the forest, her steps became brisk, and after advancing a few hundred meters, she suddenly jumped and jumped onto a big tree.

Chen Feng looked up, only to find that there was a tree house on this big tree!

This is Zhao Mei's foothold, or Zhao Mei's home.

No wonder Zhao Mei will subconsciously relax after coming to this forest, because it will make her feel comfortable and relaxed.

Chen Feng suddenly felt a little envious, he was also exploring in the ninth layer of the abyss, Zhao Mei also knew how to improve his living conditions, and Chen Feng was busy hunting the abyssal beasts or abyssal demons every day, seizing the time to improve his combat power.

Although there is no difference between day and night in the Nine Layers Abyss, people will still feel tired here.

Zhao Mei had already begun to rest, but Chen Feng couldn't stay here forever, because Chen Feng didn't dare to rest.

Once he rests, Chen Feng will relax, and once he relaxes, even if he will not be discovered by the Earth Abyss Beast and the Earth Abyss Demon, Chen Feng may also be discovered by Zhao Mei.

So after thinking about it, Chen Feng still carefully left this forest and continued to look for the Earth Abyss Beast.

Now he is not qualified to rest, at least he has to have the combat power of Zhao Mei to relax a little.

Chen Feng acted very carefully, and did not do it immediately after finding and fighting another group of Earth Abyss Beasts, but probed the surrounding environment and made sure that it was safe before making a move.

During the battle, Chen Feng thought of the situation when Zhao Mei and the Earth Abyss Beast were fighting, and deliberately imitated it.

It's not that Chen Feng wants to imitate Zhao Mei's fighting style, but to learn her fighting skills and how to burst out with the strongest attack with the smallest source force.

It is also Chen Feng who has the eye of an observer, and can see the changes in Zhao Mei's source power during the battle, so he can imitate it, if it is replaced by someone else, it will definitely be confused.

But even if Chen Feng saw Zhao Mei's fighting skills, it was definitely not easy to imitate them.

When he first tried, Chen Feng not only did not improve, but he couldn't even fully exert his original combat skills, if it weren't for Chen Feng's rich combat experience, maybe he would have suffered a loss here in this group of Earth Abyss Beasts.

After a battle, it took Chen Feng nearly twenty minutes to kill more than twenty Earth Abyss Beasts.

If it was before, Chen Feng wouldn't even be able to use it for ten minutes, and it can be seen from this that everyone has their own fighting style and fighting style, and forcibly imitating others may not be the most suitable for themselves.

But Chen Feng knew that Zhao Mei's fighting skills were really strong, and now it had no effect, because he hadn't grasped the key to it.

As long as you give him time to slowly understand the trick of this way of fighting, he will definitely be able to bring out the power of this way of fighting.

After killing more than twenty abyssal beasts, Chen Feng only found ten pieces of fourth-grade source stone ore, and his basic source power increased by 1,200 points, and then continued to look for traces of other abyssal beasts.

The battle has been going on, Chen Feng has no intention of resting at all, and when he feels tired, he finds a place to hide, rests while cultivating, and eats something by the way.

After the cultivation was over, he continued to look for the Abyss Beast.

Seven hours later, Chen Feng had killed more than a hundred Earth Abyss Beasts and Earth Abyss Demons, obtained 42 Four-Rank Source Stone Ores, and increased his base source power to 47,408, and after the increase, it was 101927!

This source force is already very strong, theoretically speaking, Chen Feng's domain value can reach 1417, after unremitting cultivation, Chen Feng finally increased the domain coverage to 1276 meters, and the strength of the domain power increased to 995 cards, and after the increase, it was 1323 cards!

The strength of such a terrifying domain power once again made Chen Feng feel a strong confidence.

The strength of the power of this realm alone was enough for Chen Feng to deal with more than ninety percent of the fourth-grade Earth Abyss Demons.

Of course, it was a one-on-one situation, once he encountered a large number of Earth Abyss Demons, Chen Feng was definitely not an opponent.

When he finished his cultivation, Chen Feng glanced at the system mall.

Because there is no change of day and night, Chen Feng is about to ignore the refresh time of the system mall.

Most of the equipment on his body is fourth-grade, only three pieces of equipment are still third-grade, and two of them are still refining fourth-grade, so Chen Feng is not in a hurry to change equipment, it would be best if he could refresh the mutation source stone.

After breaking through to the fourth grade, the effect of the third-grade mutation source stone will be discounted, and Chen Feng does not plan to use it, so it is better to exchange it for the fourth-grade mutation source stone from the system mall.

The system also knew Chen Feng's plan, refreshed it five times, and gave five fourth-grade mutation source stones, three of which increased speed and two increased source power, each mutated source stone was worth 10,000 merit points, and 50,000 merit points were consumed.

Add the 3100 merit points of the refresh mall to 53100 merit points.

After this time, Chen Feng's merit points still have 660,000 left.

It seemed like a lot, but Chen Feng knew that this merit point was not enough at all.

According to Zhang Yi, only by entering the fifth layer can he leave the Ninth Layer Abyss, that is to say, Chen Feng can at least break through to the fifth grade of combat power before he can see the hope of leaving the Ninth Layer Abyss.

660,000 merit points, I'm afraid it's not enough for Chen Feng to raise his combat power to five grades.

According to the price of exchanging source stones at the observer base, a fourth-grade source stone is worth 5,000 merit points, which can increase 100 source power.

660,000 merit points can only be exchanged for 132 four-grade source stones, providing 13,200 source power.

What is enough to do with such a little source power?

Even if Chen Feng can redeem more props from the system mall and have more choices, this merit point is too bad.

Therefore, Chen Feng felt that he would have to save a little in the future, and at the critical moment, he still counted on using merit points to save his life.
