"What's that?"

Bai Su looked dazed, she was only busy avoiding the bird just now, and didn't pay attention to the lake.

Ning Chu got up and walked to the lake.

Now that the beast had been captured by an unknown bird, and there was no danger in the lake that could threaten them, it was a good time to go down and explore.

"It looks like some kind of metal, you can help me get out of the wind on the shore, I'll go down and have a look. ”

Ning Chu was very decisive, and when he spoke, his spiritual power covered his whole body, forming a thin transparent light mask, and then jumped into the water, like a dexterous swimming fish, without splashing the slightest splash.

This lake is not small, but fortunately, Ning Chu remembered the approximate location and swam directly over.

At this moment, the sediment under the lake is boiling, and it is impossible to see at all.

But this was not a problem for the monks.

Ning Chu stretched out his palm, and when the spiritual power was running, it turned into Dao ripples, like a sieve, filtering out all the floating sand and soil, and being sent to a distance by the spiritual power.

The water of the lake immediately cleared.

Ning Chu peeled off the aquatic weeds and soon saw faint reflective spots.

After making sure that there was no danger lurking around him, he slowly peeled open the aquatic weeds and removed a fist-sized piece of metal from a crack in the rubble.

The metal block is a regular quadrangular shape, with neat nine-square grids on each face, and small patterns and words on each grid.

However, the patterns on each grid are mutilated, and they appear disorganized from one another.

Ning Chu played with it for a while, and quickly got out of the water and returned to Bai Su.

"What is this?"

Bai Su looked at the square metal block on Ning Chu's palm, and she was also very puzzled.

'Why does it look a bit like the Rubik's Cube played in the previous life?'...... Ning Chu frowned, and subconsciously stretched out his other hand and began to twist.

Click......

Sure enough, the metal body could really be twisted.

"I'll go, is it really a Rubik's Cube?"

Ning Chu showed a strange look on his face, the only thing that was different from his impression was the material, which had changed from plastic to metal, and he used to play with colors, but now it has become a pattern, which is much the same.

Could it be that there is also a Rubik's Cube in this world?

"You...... Haven't you seen anything like it before? For example, the six faces are six colors, and they are shuffled and put back together. ”

Bai Su shook his head very decisively.

"Never heard of it. ”

"That's weird. ”

Ning Chu pinched his chin and frowned slightly, if it was the kind of six-color Rubik's Cube in the previous life, he could still try to spell it out, but this one seemed to be more difficult.

The six colors have been replaced by six patterns, which is clearly a combination of a Rubik's cube and a puzzle.

What's even harder is that he doesn't have a pattern sample.

He didn't know what the original pattern was on each face, and he wasn't sure if it was complete.

What if the guy who made this 'Rubik's Cube' in the first place was an abstract enthusiast?

Ning Chu clicked and turned for a long time, and he didn't figure out a reason, but there was one thing worth marveling at.

This 'Rubik's Cube' has been soaked in the water for many years, not only is there no rust at all, but it rotates very smoothly, and the palace lattices are tightly fitted, which is simply ingenious.

It can be seen that this 'Rubik's Cube' is a rare material, and secondly, the mechanical attainments are very superb, that is, ...... Ahem, I just don't know what to use it for.

'Could it be that the cultivators of this world are so boring, just making a plaything......?' Ning Chu was unwilling to make a lot of attempts.

For example, spiritual power urging, brute force destruction, etc., all of them did not have the slightest reaction.

Moreover, with his cultivation in the Dao realm, he couldn't damage it.

"Forget it, let's put it away first, it's okay to go around, just relieve your boredom. ”

Ning Chu put away the 'Rubik's Cube'.

I don't know if the terrifying birds just now will go and return, thinking of their two 'little grasshoppers', so the two decisively chose to leave.

The direction pointed out by the Ruyi Pan is still deep in the mountains.

Ning Chu was even a little suspicious, the cultivation of the distant mountain path leader didn't seem to be high, what did he rely on to go so far?

And when Bai Su asked Elder Qi Yuan's whereabouts, the direction pointed by the Ruyi Pan remained unchanged.

It seems that they did go deep into the mountains.

The two continued on their way, more cautious along the way.

Ning Chu even summoned Tuxing Sun and some small animals with low cultivation to explore the way, although it would consume some spiritual power, but the effect was not bad.

In many cases, it can be warned in advance, so that the two can avoid danger.

And so it was until three days later.

The two of them came to the foot of an extremely high mountain range.

This place is inaccessible, Ning Chu has felt the breath of the fierce beasts of the Freedom Realm more than once, and even the demon beast father of the Immortal Realm has encountered it twice.

Fortunately, Tuxingsun warned in advance, and the two avoided it without danger.

And the reason why they stopped in front of this towering mountain range was because the Ruyi plate had failed after arriving here, and the little Ruyi on the jade plate seemed to have been disturbed by something and spun around.

This scene reminded Ning Chu of the compass.

This can also be the case when the compass is experiencing a strong magnetic field interference.

Although the Ruyi Pan failed, both of them had a hunch that the people of the Far Mountain Dao must have been to this mountain in the first place.

Ning Chu looked up, and couldn't help but hesitate a little in his heart.

The mountain was so tall and vast that he couldn't see the top of it with his eyes.

From the mountainside, the mountains turn white, and there is not a single vegetation under the snow-covered cover.

'Everest is a dwarf under this mountain range. ’...... Ning Chu grinned, like an ant looking up at the towering giant, and he couldn't help but feel a sense of insignificance in his mind of the Dao realm.

Bai Su looked sideways and found that this mountain range is endless and magnificent!

The other peaks, though not as exaggerated as the ones in front of them, are also towering into the clouds, which is simply indescribable.

"How's it going, are you still on it?"

"When...... Of course!"

Ning Chu's answer was very unconfident, but no matter what, he had already come here, and it seemed a little unreasonable if he didn't go up and take a look.

"Take a look, and if you find a big danger, retreat immediately. ”

"Good!"

After breathing a sigh of relief, the two continued to climb the mountain.

Although the mountain is steep, it also has a little benefit.

That is, there are very few fierce beasts, at least the two of them have not encountered too powerful fierce beasts.

It wasn't until we reached the mountainside that the green vegetation gradually thinned, the cold wind whirred, scattered snowflakes were blown up, and the temperature plummeted.

Ordinary people would certainly not be able to survive in such an environment.

But to them who ask the Dao realm, it's nothing.

However, this was only the beginning, as he continued to go deeper, Ning Chu was embarrassed to find that their location was actually not a mountainside at all, not even a tenth of the height.

The air was cold, the snow was heavy under his feet, and the biting cold wind already needed to mobilize spiritual power to resist.

It wasn't until night fell that the two walked two-tenths of a height.

After finding a leeward col, Ning Chu used his spiritual power to dig a snow cave, took out the demon beasts he had killed before, and put them on the flames to barbecue.

In this quiet and cold barren snow-capped mountain, it has a unique flavor.

"You say, is the chief of the distant mountain road full of food, and he has to run to a place where this bird doesn't. ”

Ning Chu grumbled while nibbling on the barbecue.

But after saying this, he suddenly realized something, glanced at Bai Su, and the two of them exclaimed in unison:

"Measure the sky!"

Yes, if the people of the Far Mountain Dao want to measure the height of the sky, they naturally have to find the highest point.

In other words, he was looking for a place closest to heaven.

'Then what kind of horror did he suffer when he measured the sky?' It can't come down from the 'sky', right?' Ning Chu was startled by his own conjecture, and his chest rose and fell violently.

Is it 'immortal'?

It wasn't until this moment that he was truly aware of the danger.

He even experienced the original mood of Fang Yan and Elder Mo.

No wonder they pressed the cause of Qi Yuan's death and didn't dare to find the real culprit, if it wasn't good, it would be a disaster to destroy the sect.

At this moment, even Ning Chu hesitated.

Do you really want to go up again?

At night, the cold wind hunts, even if the snow everywhere still looks a little gray, and the silence of the mountains is oppressive.

It seemed that out of sight, there was a large mouth of blood that devoured living beings.

Ning Chu couldn't help but shudder, and the sense of foreboding in his heart lingered......
