In fact, the real 'Holy Flame' had already been consumed, and the 'Holy Flame'-Ice Crystal Combination that Mu Chen saw now was not really a substance formed by the combination of the 'Holy Flame' and the Ice Crystal.

In fact, the 'Holy Flame'-Ice Crystal Combination at this time should be the ice crystal after being quenched by the 'Holy Fire', and it is precisely because this ice crystal is also an extraordinary treasure that refining this ice crystal consumes all the 'Holy Fire' breath.

The highest level of the ice element and the fire element is the fusion of ice and fire, so the ice crystals after the 'holy fire' will become the 'holy fire'-ice crystal combination in front of you.

But no matter how this ice crystal changes, its essence is still a treasure that needs to be nourished and fed back with the help of Mu Chen's spiritual power, so when Mu Chen pushes the 'Holy Fire'-Ice Crystal Combination, he will feel the consumption of his own spiritual power.

However, Mu Chen didn't know the detailed reasons for this.

What Mu Chen knows is that now this 'Holy Flame'-Ice Crystal Combination seems to have finally been recognized normally, and Mu Chen can rest assured that this 'Holy Fire'-Ice Crystal Combination is a means to press the bottom of the box for himself.

"Now, let's go back the way we came?"

After a long period of experimentation, Mu Chen and Song Qi had almost figured out what this 'holy fire'-ice crystal combination could help Mu Chen at this time.

There is no other place to search for this cave now, Mu Chen and Song Qi have finished resting, and it is time to go to other places to explore again.

"Let's go, let's go back the way we came, there's no other exit here!"

After carefully perceiving that there was indeed no other breath around them again, Mu Chen and Song Qi turned back with satisfaction and returned along the tunnel where the two came in.

This time I went to the Ocean Blue Hole, and it was already a good loss.

But that's just for Mu Chen.

For Song Qi, it seems that there is no other change except for raising the cultivation level to the Mahayana period.

However, it is no wonder that Song Qi is not surprised, because the two treasures that were finally discovered, the 'Holy Fire' and the Ice Crystal, were both given to Mu Chen by Song Qiqian, and Song Qi did not absorb the slightest.

Although Song Qi seemed to be quite satisfied with the gains of coming to the Ocean Blue Cave this time, Mu Chen saw that Song Qi had not absorbed any treasures, and his heart was always unbalanced, and he secretly decided in his heart that he must find a treasure suitable for Song Qi again!

......

After walking for more than an hour in the long and boring tunnel, Mu Chen and Song Qi finally walked out of this tunnel and returned to the mountain range.

What caught their eyes was the mountain peaks standing again, and Mu Chen and Song Qi were about to start a long journey over the mountain again.

Because the ice crystals in this cave had already been absorbed by Mu Chen, Mu Chen and Song Qi also thought that the forbidden effect of this mountain range should have disappeared.

However, with all his strength activating the jet behind the 'Thor' mecha, Mu Chen still couldn't fly.

See, in this mountain range, the effect of the forbidden sky is still there.

This may also indicate that another treasure that exists in this mountain range has not yet been discovered by the two of them.

Mu Chen's eyes lit up suddenly.

This time, this treasure must be turned out and Song Qi can absorb it.

In fact, regarding the Ocean Blue Hole, throughout the ages, there have been no less than hundreds of strong people in the Mahayana period or the Tribulation Period who have come to experience, and most of them are strong people in the Tribulation Period.

But even so, no one can really explore this ocean blue hole.

Generally speaking, every strong person who enters this ocean blue hole and explores it will draw a map.

This is also to allow the immortal cultivators who enter this ocean blue hole later to take some detours.

Only Mu Chen also heard Qingyu say, in fact, the appearance of this ocean blue hole is not static.

In fact, the landscape of this ocean blue hole is changing at an extremely slow pace.

However, although the speed of change of the landform of this ocean blue hole is a bit slow, it is roughly estimated that the landform of this ocean blue hole will still be greatly changed every four or five hundred years.

Therefore, this is equivalent to the fact that as long as no one can complete the exploration of this ocean blue hole in this short period of time, then according to the changes in the landform, this ocean blue hole can be said to be never explored.

And because although the treasures contained in this ocean blue hole are extremely rich, for a strong person like Qingyu, it only needs some specific things, or just come to the simple experience when encountering the bottleneck of cultivation.

After these things, it doesn't matter if you don't come to this ocean blue hole again.

It is estimated that it will take a long time to explore this Ocean Blue Cave once, and if you don't urgently need the opportunity in this Ocean Blue Hole, a strong person like Xiang Qingyu will basically not come back for a second time.

And for immortal cultivators in the Mahayana period, just like Mu Chen, who is at the level of cultivation, is only in the Mahayana period to enter this ocean blue cave to explore, otherwise it is an extremely rare Tianjiao.

How could Tianjiao appear so often?

Therefore, it is because of all kinds of reasons that it is impossible for the Ocean Blue Hole to be explored in a short period of time.

But it's actually pretty good.

The ever-changing landscape can also reveal the treasures hidden in this ocean blue hole, which can also allow the people who go behind to get harvest.

Not following the rules and sticking to the evidence, this is the attitude that immortal cultivators should really have!

The maps drawn by the predecessors can only be used as a reference, although Mu Chen and Song Qi didn't even remember to borrow this map that could be used as a reference from Qingyu......

No one can answer how big the ocean blue hole is.

No one can answer how huge the treasure is.

Therefore, for the forbidden sky effect that still exists in this mountain range, Mu Chen can also be sure that there must be some other treasures here.

It is impossible for the predecessors to completely empty out the treasures of this ocean blue hole, although it is not clear what kind of mechanism this ocean blue hole is working, and they also do not know where the mysterious power that controls the changes in the landscape of this ocean blue hole comes from.

However, how could such a harmless Ocean Blue Hole (except for the immortal cultivators who died here because of their own lack of strength), whether it was Mu Chen, Qingyu, or other strong people, not like it?

For the detailed mechanism of this, I can only not seek to understand it.

If you really understand it, it may make the immortal cultivators have a greater desire, even if they hollow out this ocean blue hole, it will not be able to fill it.

Then this would be self-defeating.

However, such an ocean blue hole that continues to circulate and exports benefits to the outside world, all races have a strict fate, and it is impossible to explore it deeply!

It's just that this mountain range is so vast, and Mu Chen doesn't know where the treasures that affect this mountain range are hidden.

The surrounding mountains are vast, and the breath in the air is basically unchanged.

This is also the direction that Mu Chen simply can't use his spiritual power to perceive this treasure.

There is no exact breath change or breath release gap, even if Mu Chen perceives it, it is impossible to have the slightest reaction.

can only rely on luck completely, but Mu Chen doesn't believe in his luck anymore......

Because for so long, every time Mu Chen needs to rely on luck, Mu Chen will ......

Not perfect!

But if they wander around at will, Mu Chen and Song Qi may lose their way in this mountain range, so Mu Chen can only take Song Qi to one place.

Leaving the tunnel and continuing to climb forward, Mu Chen and Song Qi also didn't know that they had crossed a few more mountain ranges.

The sky above their heads was always gray, and it was impossible to determine the time, and everything Mu Chen and Song Qi did in this mountain range could only rely on their own perception.

Feeling that his feet were about to go sore, Song Qi also pulled Mu Chen to rest, and Mu Chen of course agreed, so the two sat down on the top of a mountain peak to rest.

Looking at the endless peaks around him, Mu Chen also felt like a ship lost in the vast sea.

Alone.

"Ah...... How big is this mountain range!"

Resting back to back with Mu Chen, Song Qi also looked at the endless mountains around him and couldn't help but complain.

"Let's go slowly, we at least have the right to choose now, compared to being trapped in the cave and unable to explore again, we have no choice but to leave, our current situation is good. ”

Hearing Song Qi's complaint, Mu Chen also smiled kindly and said softly.

seems to be comforting Song Qi, and at the same time comforting himself.

Yes, compared to if the two of them were trapped in the cave and had no exit to leave, they could only use the teleportation jade pendant to return to the Qingfeng Sect in the end, now Mu Chen and Song Qi are constantly traveling through this vast mountain range, but at least they are free, and it is much better than the previous situation.

can't complain, when Mu Chen and Song Qi entered this vast mountain range, the test of patience for the two had actually begun.

I saw Mu Chen and Song Qi resting on the top of a mountain with their backs to back, and a soft breeze blew faintly from a distance, which made the two of them feel refreshed.

But......

Breeze?

How could there be such a natural majesty and such a warm feeling in the middle of this mountain range?

Although such a pleasant breeze relaxed Mu Chen and Song Qi's tired body and mind, it also aroused Mu Chen's vigilance.

Could it be that along the direction of this breeze, there are treasures?
