"But before leaving, we have to see if Xiao Hei is still alive. ”

On the system interface, Xiao Hei's phantom has disappeared, but Chen Mu still has a trace of luck, hoping that the distance is too far, causing the signal to disappear.

He swam to the shore and climbed to the top.

"Click......"

After the alienation, the hands and feet, no, should be regarded as claws, and they were easily inserted into the stone, Chen Mu almost wanted to cry.

The rock wall is full of traces of being swept by the giant beast's pillar of light, and there are potholes, and in some places there is still falling rubble, but fortunately it has not collapsed entirely.

When Chen Mu passed by a large pit, he saw that behind the outer stone wall, there were gray rock formations.

He climbed in and tried it, and the rock formation was very hard, like the one that came out of the river valley, as if the gray rock formation was under the whole snowfield.

Stop and stop all the way, try to find Xiao Hei, but unfortunately there are too many pits, God knows which one was smashed by Xiao Hei.

Chen Mu searched for a while, but found nothing.

But just as he was about to change directions and continue looking, a small black phantom on the system interface flickered and appeared.

He was immediately overjoyed, and his four claws flew together, and he slashed inside, and the little black phantom flashed a few more times.

I dug until the gray rock layers came out, and finally found Xiao Hei.

It was only the size of a puppy, and it lay there softly, dull.

"Blackie, wake up!"

Chen Mu shouted while looking at the system interface, Xiao Hei's phantom had appeared steadily, but it was very shallow, he must still be alive, but his vitality was seriously injured.

He reached out and pressed it on Xiao Hei's body, trying to inject European qi into it.

Xiao Hei feeds on dead air, and Ou Qi has very little effect on it, but it is better than nothing.

The black fire is symptomatic, but Chen Mu has no extra black fire to mobilize.

The black light in the sea of qi is already a rush for the mud bodhisattva to cross the river and it is difficult to protect himself, and even the immortal fire is difficult to urge, how can there be any surplus food to relieve Xiao Hei.

After transporting European qi for a while, Xiao Hei finally regained consciousness, barely condensed into a human form, and had no strength to speak.

Chen Mu hung it around his neck and turned his head to climb towards the dark river.

Entered the river, all the way upstream, to the junction of the river valley and the dark river.

This is a sinkhole, a super waterfall that rushes down 3,000 feet, with a faint glimmer of sky light above, and the color of the top of the waterfall is also dark red, which does lead to the river valley.

If it was before the alienation, Chen Mu could really only look at the ocean and sigh, and it would be impossible to go up at all.

It's not that hard now, the claws are like impact drills, and they can easily pierce into the rock.

He krypton gold, recovered his European qi slightly, and began to climb.

Bypassing the massive impact of the water from the side of the waterfall to the back of the fall, the rocks are so slippery that they are simply unsettling.

"Click......"

Chen Mu repeated his old skills, using his hands and feet at the same time, leaving small holes on the stone surface like a pile driver, and climbing steadily upward.

Just climbed and rested for a while, and after half a day, his whole body was very sore, but he still couldn't see the top above.

Looking back and looking down, I was obedient, I had climbed so high that I couldn't see the bottom, and I would definitely fall if I fell.

Looking behind me, the roaring waterfall rushes down, blocking the view and making it impossible to see the outside scene.

"No, let's dig a hole and rest. ”

It was convenient to be able to make a hole, so he worked hard to dig a hiding hole in the stone face and drill into it.

The hole is not big, you have to curl up, the stone here is cold and biting, fortunately it has its own heating after the alienation, otherwise it would have frozen to death.

Chen Mu was so hungry that he couldn't do it for a long time, but fortunately, Xiao Hei had devoured the heart and flesh of the giant beast before, and although most of it was scattered when it was knocked away, there were still some left.

He had eaten half of it before, consumed some more along the way, and now there were two fist-sized lumps left.

After the alienation, the teeth have also become shark-like sharp teeth, densely packed with cold light, and it is a small case to eat alive or something.

Chen Mu took out a meat ball and ate it in three or two bites, still hungry in his stomach.

He held back his appetite and didn't move the last lump of meat, letting Xiao Hei take it into his belly.

After Xiao Hei's body became smaller again, he didn't seem to have much vitality, and his speech was a little intermittent, and it seemed that he couldn't be resurrected, and if he was attacked again, he would probably kneel completely.

Chen Mu sighed secretly and counted the resources at hand, the white bone relics and the reincarnation scriptures were still there, which was a blessing in misfortune.

Most of the gold carats were lost, and the rest consumed some more, and now there are less than ten left, and there is not one with attributes, and it is simply a blood mold.

"Well, this time it's a night back into poverty, and if the monkey was still there, I would have fed it all in the first place. ”

Thinking of the monkey, he was a little depressed, and he didn't know where the monkey and Pipsqueak were now, whether they were still alive, and when they would be able to meet again.

After being depressed for a while, Chen Mu forcibly cheered up, only if he was alive would he have tomorrow, so he would escape first.

was about to go out and continue to make a hole, but Xiao Hei suddenly moved, drilled into the hole, and rubbed against the stone wall.

"Damn, Xiao Hei, what kind of plane are you doing?"

Chen Mu looked at the chrysanthemum tightly, and didn't understand how Xiao Hei could be interested in the stone.

Xiao Hei rarely ignored him, and rubbed for a while before he said intermittently: "This, there seems to be dead air in this, I want it, I want dead air to repair my body, I need it urgently, otherwise my body is about to collapse." ”

"Dead air?"

Chen Mu has a high degree of trust in Xiao Hei, after all, he is a war pet bound on the system interface, and he can detect his thinking through his consciousness, it is impossible to lie, and his loyalty is only higher than that of a monkey.

Seeing that Xiao Hei was in urgent need of death to continue his life, he didn't dare to delay, so he threw off his arms and dug inside.

As for whether there is danger, it can't be more dangerous than in the gray world, besides, my brother is also a person who has seen several big scenes now, and his courage is not so small.

I dug all the way inside, but I didn't encounter a gray rock layer, otherwise I really couldn't dig it.

After digging for about ten minutes, Xiao Hei clearly sensed the dead air.

"Master, a little to the right...... Here's a little bit...... Yes, in this direction, continue to ......"

It had countless tiny holes cracked up and down its body, not letting go of any trace of dead air, and quickly pointed out the direction of excavation for Chen Mu.

After digging like this for almost two hours, Chen Mu was so tired that he ate the rest of the meat ball, and the talisman European qi continued to wear out, and the krypton gold never stopped, otherwise the claws would have dug up baldness.

"Boom-"

Suddenly, he dug a hole in the stone wall with one claw, and he actually dug through it.

The hole was pierced and a thick gray mist overflowed, it was dead air!

"Shall I dig into the Gray Realm?"

Chen Mu was taken aback, but quickly denied this possibility.

It's not that there is no underground gray world, but this dead air is wrong.

According to the information he had, the gray realm does not distinguish between above ground and underground, as long as the conditions are met, it can produce the gray realm at the boundary of the Kuroshio area, and some special terrains can produce underground ash realms.

But the dead qi in the gray world, that is, the gray fog, is definitely a negative attribute, it can also be said to be negative energy, and there are many characteristics, which are very easy to identify.

But the dead air in front of him is a chaotic attribute, and it even contains a part of positive energy, that is, it protects positive energy and negative energy at the same time, and magically there is no conflict, so it coexists and merges into one.
