There was still a thick smell of crude oil wafting in the air, Xi Chen frowned, and took out the wind system to emit a gentle and extremely natural wind, slowly blowing away these smells. Pen, fun, and www.biquge.info

She wasn't in a hurry to find where the dozen or so Oilspirits were hiding, and what she had just done to them was not only the psychedelic effect of the Charm ability, but also some other dark chess.

If you wait a little longer, the dozen or so spirits will fight among themselves, devouring each other until the last strongest spirit remains.

So during this time, they can take a good look at this big underground hole.

But there's really nothing to see, and everywhere is empty, except for the rock walls of mud and dry grease. But the formation of these dozen spirits is afraid that it will not be so simple, so Xi Chen will slowly 'walk' under this dark underground.

When Xi Chen was 'walking' in the dark cave, the dozen or so spirits had already begun to bite and devour each other with red eyes, and the movement was so loud that it came up from the deep underground, and even Xi Chen could clearly feel it only in the shallow layer of the dark hole.

Fortunately, before entering the burrow, she asked the formation mages to lay a lot of formations around here, and even if someone came nearby unintentionally or intentionally, it would not be noticeable from the outside.

She is determined to get the oil essence, but unfortunately the oil essence is polluted, so she must let these oil essences devour each other, and when there is only one left, the foreign matter in it will be removed, so that it can be left for her own use.

Taking advantage of the opportunity for these oil spirits to devour each other, she had to take a good look at where the unexpected factors that polluted the oil essences and caused them to produce spirits came from.

Xi Chen quietly went underground, passed the scene where more than a dozen spirits fought and bit very fiercely, and went deeper underground. There, there was some aura similar to that of the spirit, and it loomed over.

If it weren't for her amazing five senses, I'm afraid she wouldn't have noticed it.

Following that breath, Xi Chen didn't know how much he went deep into the ground, and finally reached the end, but there was no way out.

The breath wafted out of a crack that could be seen, but not even a child could get into it. It is not difficult to get into this crack, but the difficulty is that the aura wafting out of it is getting stronger and stronger, and it is becoming more and more unsettling.

There is a thick bloody aura in this breath, and it is no wonder that those spirits are ferocious and murderous after being infected by it, and they have no reason.

It's just that he has already chased here, and it really doesn't make sense to ask Xi Chen to give up. The last thing that she couldn't give up was that there was a faint aura mixed in with those thick bloody gases. The reason why those oil essences were able to form must have been influenced by this breath.

However, although the spirit was formed, it also lost its mind due to the heavy bloody aura.

Xi Chen hesitated for less than a second, but still made up his mind to move forward.

She was very interested in the aura mixed with blood, that is, she had traced it here, and there was no reason to give up.

She and Qianfan both used the Earth Escape Technique, and traveled for miles through the hard underground for several miles, and finally came to a lonely underground space: in a small cave, an ancient seal suddenly appeared.

Blood flew on the seal, and the aura was very heavy. Perhaps because of the expiration of time, a trace of pale aura emerged from it, breaking through the barrier of the blood-colored seal and wafting out.

Xi Chen's heart was clear, there was a hint of divine power hidden in the faint white breath, needless to say that this oil field would only produce more than a dozen oil essences under the influence of the breath. And the oil essence is infected by the blood-colored evil qi that comes out of the whitish white breath at the same time, so it will be so violent.

It's so much fun!

Looking at this ancient seal, it was at least tens of thousands of years ago, and at that time, the written Water Blue Star civilization had not yet been born. But if you want to trace back to the legendary ape-man civilization and beyond, there are tens of thousands of years.

Xi Chen didn't expect that on a mortal planet like Shui Lanxing, there used to be a great god level. Otherwise, where did this heavy blood-colored seal come from? Under this seal, I'm afraid it's also a heavyweight.

Look at the breath in the seal that has a faint sense of influence on her, no matter how fierce this blood-colored seal is, she has to find a way to open it.

After Xi Chen groaned slightly, many array flags and formation talismans continued to flash out in her hand, and she summoned a few monks with excellent formation skills, and began to set up the formation after a discussion.

It is still a combination array, mainly to absorb and consume the energy of this blood-colored seal, supplemented by preventing the overflow of ferocious blood qi.

This blood qi is too strong and evil, if it all overflows, it will not only be the dozen or so spirits that will be infected, but any creature infected by it will become delirious and murderous.

It was precisely because this seal was so bloody and evil that Xi Chen had to erase it from the water blue star no matter what it sealed.

It's just that her current ability is limited, and she can only deploy the highest-level formation group that she is currently capable of to slowly weaken and eat away this blood-colored seal.

Otherwise, with the means of her greatest strength, she would have been able to break this seal in seconds. Hey, the hero doesn't mention the courage of the year......

In addition to these, layers of defenses must be laid to prevent foreign creatures from breaking in again and being bewitched.

Because of the abundant materials and manpower, the formation group was arranged quickly, and dozens of large and small formations were laid out in half a day. For a while, there are those who absorb the blood evil qi, those who weaken the blood evil qi, and those who transform the blood evil qi......

As soon as the formation was arranged, a few people were left to stick to the formation, and Xi Chen turned around and went out: the dozen or so oil spirits had been fighting for a long time, and they must have fought almost the same.

As she expected, as she walked up to the holes in the ground, only one of the dozen or so oil spirits remained.

Because of devouring other similar species, this oleogen is several times taller than before, and it is also condensed several times.

It's just that the furious red in its eyes is deeper, and when it sees Xi Chen walking around, the red light flashes and pounces.

The essence of oil has only just taken on a human form, and it has not yet developed its intelligence, and it has not yet developed its senses, and it has not yet been infected by blood and qi. This rush is not only extremely powerful, but also faintly carries a pungent smell and poisonous gas.

The poisonous gas emitted by it is naturally the specific poisonous gas contained in crude oil such as petroleum gas, benzene and aromatic hydrocarbons, and hydrogen sulfide, which is extremely harmful to people.

Xi Chen flashed sideways easily: To deal with this oil essence, you can't use physical attacks. The sticky surface of its body, slashed not only could not hurt its essentially liquid body, but was also stuck by it. The light ones affect the attack speed, and the heavy ones are trapped in it, and they can't advance or retreat. (To be continued.) )
