Returning to the fifth layer, Chen Feng didn't bother whether he could return to the xenomorph world, because he could continue to stay in the fifth layer to cultivate, or even enter the sixth layer.

It doesn't matter if the exit is blocked now and he can't leave, when Chen Feng's combat power is strong enough, he wants to see who dares to block the exit!

Be open-minded and do everything smoothly.

Chen Feng casually swept several Abyss Beasts and Abyss Demon Tribes on the fifth layer, collected more than a hundred Source Stone Ores, and encountered three Royal Abyss Beasts on the way, and obtained three Royal Abyss Beast Heart Cores after killing.

Coupled with the heart cores that Chen Feng had obtained from killing the Royal Clan's Abyss Beast before, at this time, Chen Feng's backpack actually had seven Royal Clan's Abyss Beast Heart Cores and 153 Source Stone Ores.

Together, these Royal Abyss Beast Heart Cores and Source Stone Ore can increase the base source power by 130,000!

Chen Feng smiled and prepared to cultivate again.

After this cultivation is completed, his combat power should be able to break through to the fifth rank and ninth order.

At that time, Chen Feng will enter the sixth layer, first test the combat power of the sixth layer royal family, and then decide what to do next.

Two days later, Chen Feng's cultivation was over, and the basic source power had increased to 2167917, and after the increase, it was 5268038!

Five-grade and ninth-order combat power!

The field coverage is 19,399 meters, and after the increase, it is 22,308 meters, and the power strength of the field is 17,399 calories, and after the increase, it is 28,360 calories!

is only more than 700,000 source power away from the six-rank combat power!

According to Chen Feng's current efficiency, as long as there are more than five hundred source stone ores, it will be enough.

But Chen Feng didn't want to wait.

Relying solely on cultivation to improve combat power was not what he wanted.

Only through continuous fighting and constantly feeling the pressure brought by the strong can Chen Feng's combat power be fully exerted and achieve greater improvement.

Of course, before entering the sixth layer, it did not affect Chen Feng to continue to sweep the Abyss Beasts and the Abyss Demon Tribe on the fifth layer, and by the way, he killed all the royal clans and Abyss Demons he encountered, and scavenged their old nests.

It's one thing not to be in a hurry to cultivate, but it's another thing to accumulate cultivation resources.

It is also that the system does not have the business of recovering source stone ore now, otherwise Chen Feng can search for a few more days on the fifth layer, and first engage in his 100 million merit points!

The boundary between the fifth and sixth layers is still obvious, and there is an obvious gap, which is to let the abyss beasts and demons of the ninth layer of the abyss know that this is the boundary here, and they should not cross it easily.

Chen Feng didn't think much about it, he directly crossed over, and then found that the energy intensity of the sixth layer was far greater than that of the fifth layer!

With such a powerful energy intensity, even if there was no source stone ore, the cultivation speed here would be more than twice as fast as in the fifth layer!

It is no wonder that there are so many high-grade combat power among the xenomorphs, it turns out that it is not only because the xenomorphs have survived here for a long time, but also because the resources they can obtain are too much more than the resources that humans can obtain.

In addition to the energy becoming richer, Chen Feng also found an obvious change, that is, the number of abyssal beasts and abyssal demons in the sixth layer had obviously decreased a lot.

Think about it, too, any system of power will eventually form a pyramid structure, that is, the stronger the combat power, the smaller the number.

This is true for humans, and it is also true for xenospecies.

After the combat power breaks through to the fifth grade, the direction of cultivation begins to change, you can major in combat skills, domain skills or domain power strength, etc., or you can choose to improve in an all-round way.

But the above is not easy to improve, the development of combat power restricts the improvement of many human abilities and xenomorphs, so the number between the fifth-grade combat power and the sixth-grade combat power has really been significantly reduced.

It is foreseeable that as Chen Feng's combat power continues to improve, when he breaks through to the seventh or even eighth rank, the number of xenomorphs will decrease even more significantly.

If he can break through to the Nine Grades, he may find that the number of Nine Rank Xenos is actually not much.

Suppressing these thoughts for the time being, Chen Feng began to look for a suitable target on the sixth layer.

Now that you have entered the sixth layer, you must find a way to break through as soon as possible, instead of staying here all the time.

Only after breaking through can Chen Feng grasp the initiative, and he can choose to leave from the exit of the fifth layer, or he can choose to continue cultivating at the sixth layer and find an opportunity to leave from the exit of the sixth layer.

It is estimated that the Xenomorph Royal Clan and the Dark Jungle would not have imagined that Chen Feng would break through to the sixth rank in such a short period of time.

Of course, Chen Feng couldn't stay on the sixth layer for too long, otherwise the Xenomorph Royal Clan and the Dark Jungle would find something different sooner or later.

At that time, Chen Feng may face a more fierce pursuit.

Simply taking a turn around, probably because Chen Feng was still on the edge of the sixth layer, he only found two groups of abyssal beasts, and the number was about 20-30.

Although it has broken through to the sixth grade, the Earth Abyss Beast still can't change its habits and likes to live in groups.

Chen Feng took a look, the highest combat power in the Earth Abyss Beast Clan was only the sixth rank and third order, with a source power of 8 million, and although the attributes in all aspects were not bad, it was almost the same as the fifth rank of the Royal Earth Abyss Beast, so Chen Feng had nothing to worry about.

After all, the attribute bonuses brought by the identity of the royal family are still obvious.

In the face of the royal clan's abyssal beasts, the role of the realm could not be brought into play at all, but Chen Feng did not hesitate at all, and directly attacked, relying on his powerful attributes and speed advantages, it only took less than three minutes to destroy this abyssal beast race.

But when searching for the loot, Chen Feng only found three sixth-grade source stone ores, each of which could increase the source power by 2,200.

The effect of six-grade source stone ore is much stronger than that of five-grade source stone ore, but the quantity is also too small.

I just don't know if I can find the source stone mine.

As long as he can find the sixth-grade source stone mine, Chen Feng is sure that he will break through to the sixth-grade in a short period of time, and when the time comes, those sixth-grade alien royal clans and black-clothed people who are guarding the exit of the fifth layer will not be a problem.

Chen Feng continued to move forward, clearing out the second Abyss Beast Clan, and obtained three more sixth-grade source stone ores.

This efficiency is really low.

One piece of sixth-grade source stone ore is equivalent to four pieces of fifth-grade source stone ore, that is, Chen Feng cleared up two abyss beast groups before he got the equivalent of 24 fifth-grade source stone ores.

If this was placed on the fifth layer, Chen Feng would have such a benefit from casually destroying an Abyss Beast or an Abyss Demon Tribe.

If Chen Feng hadn't felt that since he had already come to the sixth layer, he would have explored well in the sixth layer, and maybe there would be other gains, he would have turned around and returned to the fifth layer a long time ago.

After all, in the fifth layer, not only is the income high, but the security is also guaranteed.
