If the black dragon has a lot of this thing, there must be a surplus to bring with him, and if he encounters the black dragon head-on, the black dragon releases this thing, they are not good, because this thing can not only freeze people, but also freeze divine consciousness, needless to say, it has a great suppressive effect on the exertion of their strength!

So, instead of simply destroying a hole, it is better to find out the magic of the hole.

Mad Shura carefully probed the surrounding movements, and confirmed that the black dragon was not at least in the first and second peaks, so he signaled that he could do it.

Lin Xi used three kinds of Origin Dou Qi, relying on the explosion effect after the Origin Dou Qi was mixed.

This effect has been verified many times, although the power is not as strong as the attack of the powerhouse of the demigod realm, but it has a unique explosion effect, which is the most suitable for piercing this hole.

The Kirin Lion and the Wild Asura teamed up to set up a barrier to prevent the sound of the explosion from spreading, as well as to prevent the dirt and flying stones from the explosion from flying out.

Lin Xi faced the hole with his arms and blasted out the three origin fighting qi of gold, fire, and earth, and soon, these fighting qi jumped into the hole.

Then there was a tremor on the ground, and a lot of dirt mixed with stones erupted out.

By the time the storm had subsided, the hole had already been blown open by about fifty meters!

Of course, there must be a long way to go from the bottom end of the hole.

However, after the falling stones and mud blocked the cave, the nearby dead cold no longer gathered at the peak as before, and it seemed that it would be easy to destroy the cave.

However, until he saw that mysterious substance, Lynsey would not stop.

Keep bombarding.

The hole kept blowing up, revealing more and more parts.

Soon, the height of the explosion was at least five hundred meters, which far exceeded the height of this mountain, and there was no doubt that this cave led to the depths of the earth!

"Alright, Linsey, let me use my mind to probe again. Crazy Shura said.

The depth of the cave was reduced by five hundred meters, and the mad assura thought that his divine sense should be able to detect the mysterious substance.

But after being busy for a while, Mad Shura raised his head and said helplessly to Lin Xi, "You can blow up some more." ”

Dare to love, not yet!

Lin Xi didn't say much, and continued to blast out the original fighting spirit.

Finally, the hole was blasted open for a full kilometer!

Madness Shura tried again.

Then, he jumped like thunder, jumped to his feet and scolded the black dragon: "How did this hole come out, it is so deep, it is simply unfathomable!"

The mad Shura continued to maintain the barrier in a resigned manner, and could only let Lin Xi continue to blow up the hole.

Lin Xi seized the time and kept blasting out the original fighting spirit.

The further back, due to geological reasons, the hardness of the soil layer became harder and harder, and the effect of the explosion gradually weakened, but Lin Xi still quickly pierced the hole to a depth of 2,500 meters!

Two thousand five hundred meters!

No one thought that this distance would be so deep!

And yet the mysterious substance has not been seen.

However, this time, the mad Shura used his powerful divine sense to investigate, and finally found out the secret.

"It's a fist-sized ice spirit stone. Mad Shura withdrew his divine sense, his face very surprised.

"The temperature of the Ice Essence Stone is lower than that of the Ten Thousand Years Mysterious Ice, with it, even a small city can be sealed by ice, although this Ice Spirit Stone is only the size of a fist, not too big, but the black dragon can get it, it should also take a lot of strength, after all, this kind of thing is very rare, just like the elixir Red Blood Wild Ginseng. The unicorn lion explained.

"And that black dragon obviously has at least ten ice essence stones, and one is bigger than the other, as for it, there may be more, I can't figure it out, such a precious and rare ice spirit stone, could it be that the black dragon found a whole piece and cut it?" said Madness Shura.

Hearing what the two seniors said, Lin Xi had a little understanding of this ice spirit stone, it seems that this ice spirit stone rarely appears, and it is not a simple thing to get.

"With this small Ice Spirit Stone, can we gather so much Death Cold Aura?" Lin Xi was puzzled.

"This is exactly the terrifying nature of the Ice Essence Stone, the cold gas it produces is much more terrifying than that in the Snow Region, and the death cold breath has the same attributes, so it can naturally be absorbed by the Ice Essence Stone. Mad Shura explained.

At this time, the unicorn lion finally said after careful thinking: "The black dragon is to use these ice essence stones arranged in the mountain peaks to gather more death cold breath for its use, if we want to destroy, we must destroy all the ice spirit stones on all the mountain peaks at the same time, right now, the ice spirit stones of this one have been destroyed, and the dead cold breath gathered has become less and less, I am afraid that the black dragon will find out, so we must make the other ice spirit stones lose their effect as soon as possible." ”

"But what if one of the peaks is inhabited by a black dragon?" Madness Shura didn't want to wake up the black dragon in advance.

"I guess the black dragon should be on the tenth peak, not even in the peak, but behind the tenth peak. The unicorn lion said, "I said that these ten peaks are like a magic circle, and the black dragon just has to rely on this thing to get more dead cold breath, and it shouldn't live in the magic circle, even if it lives in it, it will be there in the tenth mountain." ”

"So, we're going to block all the ice essence stones on the nine peaks in front of us, so that this magic circle will be ineffective?"

"Act separately. The unicorn lion didn't say anything more, but flew up first, flying towards the seventh, eighth, and ninth peaks.

The Wild Asura flew to the fourth, fifth, and sixth peaks.

Lin Xi also used the "Walking with the Sword", stepping on the fiery red broadsword, and quickly flew towards the second and third peaks.

The three of them directly used the simplest and most brutal method, which was to block the hole with countless dirt and stones.

The Dead Cold Breath lost the sense of the Ice Spirit Stone, and immediately became scattered and floated, no longer gathering on the mountain peak.

Only five minutes have passed since I was done.

Immediately, the group quickly evacuated the area, staring closely at the tenth mountain peak in the dark.

The group didn't expect things to go so smoothly either.

Now, it is equivalent to destroying most of the first line of defense of the black dragon's lair, even if you have to encounter the black dragon head-on in the future, you can be less affected by the breath of death and cold.

However, the group waited for ten minutes, and they didn't see any unusual movement coming out of the tenth peak and behind the peak!

With the strength of the black dragon, when there was a mutation in the nine mountain peaks in a row, and a large amount of dead cold aura was suddenly lost, the moment the mutation occurred, but ten minutes had passed, and the black dragon did not move!

This is clearly counterintuitive!

"Isn't the Black Dragon here?" said Lynsey.

"There's another possibility, the black dragon is here, but it just doesn't feel it, just like some animals hibernate in winter, and the black dragon may be in some kind of metamorphosis, so it fell into a deep sleep and didn't wake up. The unicorn lion said.

"Go to the tenth mountain and have a look?" said Wild Shura eager to try.
