The group is not a timid and afraid person, not to mention that now the black dragon has not come out when the nine peaks have been destroyed, there is obviously some reason for this, if you blindly cringe and refuse to seize the time to act, the opportunity, but once it is gone, it will not return.

Therefore, at the same time, the group quickly approached the tenth peak under the cover of the mountain peak.

The tenth peak is also 100 meters high, but the area is nearly ten times larger than the first peak!

The group went straight to the summit.

The summit is completely different from the summit of the previous nine mountains.

Because this is actually cloudy!

If you look closely, everyone is shocked!

What kind of cloud and mist is this, it turns out to be the breath of death cold!

"It seems that my estimation is not wrong, the death cold aura gathered by the nine peaks in front of them relying on the ice spirit stone has been sent here, needless to say, this must be the habitat of the black dragon. The unicorn lion said.

"But the strange thing is that now that we are all here, although the commotion is not big, ordinary people may not be able to find it, but the black dragon is the supreme powerhouse in the middle of the demigod realm, and it is impossible and there is no reason not to find out that we are in action. The mad Shura still looked a little puzzled.

"Whatever," the Qilin Lion boldly judged at this time, "The black dragon may not have discovered us for some reason, so let's hurry up and finish investigating the movement here and destroy the last piece of ice spirit stone." ”

With that, the unicorn lion walked towards the center of the mountain first.

After advancing about a hundred meters through the thick death chill, the group stopped again.

"It turns out that the black dragon relied on this method to collect the breath of death cold. Crazy Shura said.

What appeared in front of everyone was not a small deep hole, but a large pit, which was at least a thousand square meters in area and more than fifty meters deep.

In the center of this large crater, there is a large glass sphere.

The large transparent glass ball stands upright, and there is a ten-meter-thick pipe connected to it at the bottom, which is responsible for supporting the behemoth, and at the top of the glass ball, countless tiny conduits are inserted.

Each of the tubes is still working, collecting the dead cold that pervades the area into a large glass sphere, which is then transported through the pipes below to the unknown underground.

It's a completely automated process.

First of all, the first nine peaks used the ice spirit stones buried in them to continuously gather the dead cold aura floating in the air, and then, through some mysterious thing similar to a magic circle, the gathered dead cold aura was collected and transported to the peak of the tenth peak.

And the tenth mountain peak is undoubtedly the hub where the black dragon gathers the cold breath of death.

Here, the collected death-chilling breath is channeled underground through countless conduits for the Black Dragon's use.

After understanding this, the group naturally judged that under the large glass ball, it must be the black dragon's lair.

However, the strange thing is that until this time, the black dragon did not notice the movement made by Lin Xi and the others.

"It's impossible, the ice essence stones of the nine peaks in front of you have been blocked, and it is impossible for the dead cold aura to gather again, it stands to reason that this change is big enough, why didn't the black dragon react at all?" said Madly Shura again in confusion.

The unicorn lion smiled slightly, pointed to the large glass ball in front of him, and motioned to the mad Shura to take a closer look.

"I see!" Mad Shura stared at the glass ball carefully for a few moments, and suddenly understood.

It turned out that the efficiency of this set of devices used by the black dragon to collect the dead cold breath was very high, although ten minutes ago, the group destroyed the devices used to collect the dead cold breath of the nine peaks in front of them, but because of the large amount of dead cold breath collected before, it has not been completely used up until now, and nearly one-third of it is left in the large glass ball.

It's no wonder that the black dragon doesn't notice this change.

After all, the glass sphere is still transporting the cold breath of death into the mysterious depths of the earth.

"Before the black dragon is discovered, we must find it before these dead cold breaths are exhausted. The unicorn lion made a quick decision.

But what method should be used to break through the soil and find the black dragon?

The effect of Lin Xi's Origin Dou Qi explosion was too strong, and it might alarm the black dragon.

The Kirin Lion is also good at fire attacks, and is known for its swift attacks, which is obviously not suitable for digging.

As for the little ones, not either.

And the mad Shura, the attack is extremely powerful, and it is really inappropriate to do this kind of digging thing.

Just when Lin Xi was in a dilemma, the mad Shura spoke: "Use the black broken knife." ”

The crowd didn't know why.

Madness explained, "We all entered the inner space of the Broken Knife, and before that, I introduced a force into the Broken Knife, causing the Broken Knife to break through the soil and move down. In this way, it is only equivalent to a small broken knife digging the soil, whether it is movement or whatever, it is easy to control. ”

"Can the broken knife still be used like this?" asked Linsey in surprise.

"Of course," said the mad Shura, "I can only rely on the Broken Knife to attack, so I am also familiar with the various ways to use the Broken Knife. ”

Lin Xi joked: "That dare is good, I will dig a grave in the future, and I must be right to find you." ”

"Haha. ”

Crazy Shura and the others couldn't help but laugh.

Subsequently, the group entered the broken knife, and the mad Shura brought the broken knife to the bottom of the large glass ball, inserted it straight on the surface, and then introduced a rapid force from top to bottom, directly hitting the broken knife, almost at the same time, the mad Shura also had a thought, and the person entered the inner space of the broken knife.

I saw that the broken knife that was originally inserted in the ground suddenly sank to the ground at this moment, as if it had been pressed down by life.

Moreover, the power and speed of this sinking are not small.

Relying on the power of the Crazy Shura, the broken knife was forcibly inserted into the position two hundred meters deep underground!

It wasn't until the broken knife suddenly didn't touch the soil, as if it had fallen into a hole in the ground, that it fell.

Otherwise, the broken knife can continue to be inserted!

But that's enough.

If there is a hole in the middle, it means that the hole may be the habitat of the black dragon underground.

So, the group quietly walked out of the inner space of the broken knife and came outside.

As expected, there was indeed a big hollow outside, and the diameter actually reached a terrifying range!

In this hollow, there are countless black dead cold breaths permeating the space, and the ten-meter-thick pipe really leads all the way here, continuously transporting the dead cold breath from the surface here.

The group quietly approached the center of the hollow.

He didn't go far before he noticed that all the black death chill was gone.

It didn't disappear out of thin air, but it was automatically absorbed by a behemoth crawling on the ground!
