It had been several days since the first dark silver rock giant died at the hands of the two of them.

And in this time, the two of them never met the same earthy rock giant as before.

On the other hand, almost every day, Gu Feng was able to encounter one or two dark silver stone bumps in this desert island space.

However, after so many days of fighting, plus the ancient style, the enemy is not underestimated.

Therefore, there is no such embarrassment as before.

On this day, the time is frozen at noon.

Gu Feng took Qin Yuyan with him, and the two of them wandered around in this desert island space.

In fact, for five or six days, the two of them have been searching this desert island space little by little.

The reason is also very simple, naturally I want to find the origin of the appearance of the rock giant.

Needless to say, after so many days, the two still haven't made the slightest progress.

Except for the more and more dark red crystal nuclei on Gu Feng's body, nothing else was found.

......

"Gu Feng, what did you say about the birth of this rock giant?"

For a while, facing the ancient wind in front of her, Qin Yuyan spoke out loud.

Speaking of which, the two of them had also encountered two days ago, and a rock giant formed in front of their eyes.

However, even after witnessing the whole process of the formation of the rock giant, there is still no clue.

"Forehead ......"

Regarding Qin Yuyan's words, it is obvious that for a while, Gu Feng does not have any good opinions.

After thinking about it and scratching his head, Gu Feng slowly spoke, "This thing is very weird, the two of us have witnessed the whole process, and we don't know how this thing came about." ”

Regarding Gu Feng's answer, Qin Yuyan behind him didn't feel surprised.

Her brows condensed slightly, and then Qin Yuyan said her opinion, obviously, she had a certain guess about this rock giant.

"I don't know if you found out. ”

"When these rock giants formed, the rocks that made them up were actually ordinary rocks on this desert island. ”

Seeing Qin Yuyan speak, Gu Feng also thought that she might have some opinions.

For a while, he slowed down and waited for Qin Yuyan behind him to follow.

Coming to Gu Feng's side, Qin Yuyan stretched out her hand, motioned for him to pull herself, and then continued to say her thoughts.

"In my opinion, the most important thing about these rock giants is the crystal nuclei in their bodies. ”

"But have you ever thought about where these crystal nuclei come from?"

"From the dark blue square crystal nucleus before, to the dark red now. ”

"It seems that the energy contained in this crystal nucleus has increased, so the strength of these guys has also become stronger. ”

After saying that, although Gu Feng understood that what she said was something he could understand.

But it was as if through Qin Yuyan's words, he had caught something that he hadn't noticed before.

"You mean?"

Tentatively asked, and handed over the words to Qin Yuyan again.

"I think we've been skewed in the direction of our investigation. ”

In other words, what we should be looking for is how this crystal nucleus came about. Rather than mechanically looking for these rock giants and then slaying them. ”

After saying this, Qin Yuyan's voice also stopped.

And when Gu Feng heard this, he suddenly understood what he had caught.

Actually, Qin Yuyan is talking about him.

After a few days of pursuit, Gu Feng's own focus was on finding one rock giant after another.

Then blast them to pieces, in the crystal nuclei that get into the bodies of these guys.

It had always been like this, and even, in his subconscious, when these rock giants were slain by himself, it was as if he could suddenly open up.

"When you say that, I feel like I've been straying all along. ”

As he spoke, Gu Feng also scratched his head and showed an embarrassed look on his face.

"Hehe~"

It's just that for his words, Qin Yuyan just smiled and didn't say anything.

Then, the two cautiously probed forward.

However, it didn't take long for the familiar guy to reappear.

However, this time the two of them did not have such good luck and did not see the formation process of this thing.

Looking at the rock giant that suddenly appeared, Gu Feng was not polite at all, and with the Danyang heavy sword, he crashed into it.

is familiar with this guy's moves, and the ancient style is quite careful.

So it wasn't too much of a problem, but in a moment, it was a pile of rubble.

Just when Gu Feng was about to make a move and take out the crystal nucleus of the rock bump, he was stopped by Qin Yuyan.

"Wait a minute, Gu Feng, and see what this thing does next. ”

As she spoke, Qin Yuyan had already come to Gu Feng's side, and above the cyan long sword in her hand, there was a flow of source power.

Obviously, she was also on guard, ready to bombard the rock lump and take the crystal nucleus at any time.

And then there was a very interesting scene.

Gu Feng and the two, when the crystal nucleus was about to gather a rock giant again, they slammed it over.

It has to start over all over again after half a day.

In this way, it was repeated nearly ten times before Qin Yuyan spoke again.

At the same time, she also made a move, completely killing the rock giant, without giving it a chance to resurrect.

"You say, what will happen to this thing in the end?"

The cyan long sword in his hand pointed at the dark red crystal nucleus on the ground, and Qin Yuyan's expression revealed deep doubts.

Knowing what she meant, Gu Feng didn't pick up this thing at this time.

Instead, let it fend for itself and see what happens.

It was such an unusual thought that made Gu Feng and the two see the next key scene.

Because of the repeated bombardment of the rocks around the crystal nucleus, at this time, the crystal nucleus is indeed not gathering rocks.

Emitting a faint dark red glow, the thing remained quietly on the ground.

After a long time, about two hours had passed, and just when Gu Feng's patience was about to run out, a strange scene happened.

All of a sudden, this thing began to dissipate.

The two of them who noticed this scene suddenly came to their senses, and they both carefully observed the next scene.

I think it is precisely because of this that the two are conducive to the next key breakthrough.

About half an hour later, Gu Feng and the two finally discovered the abnormality again.

"Say, why didn't the energy dissipated by this thing melt into the air?"

For a while, this sentence of the ancient style played the role of the finishing touch.

Almost instantly, Qin Yuyan thought of a possibility, and then blurted out: "Underground!"

"All the energy that escaped from this thing has been transferred underground!"

When she said this, Qin Yuyan also looked at the ancient style beside her, and suddenly, both of them suddenly became enlightened.

And at this time, Gu Feng also took the last bit of crystal nucleus in his hands.

After Gu Feng's action, the strange thing was that this square crystal nucleus was not dissipating energy.

Tentatively, put this thing on the ground again.

Sure enough, Gu Feng saw that this crystal nucleus had begun to escape energy again, and the energy that escaped was the same, entering the bottom layer.

At this time, I believe that anyone understands that the strangeness of this desert island space is in this bottom layer!

"Yuyan, do you remember that on this desert island, there are caves and the like, which can extend underground?"

His eyes fell on Qin Yuyan on the side, and Gu Feng immediately asked.

Qin Yuyan naturally knew what he meant, and frowned for a while, thinking about what Gu Feng said.

However, whether it was Gu Feng or Qin Yuyan, at this time, they didn't think of anything related.

"Looks like we're going to have to search this desert island space again. ”

After thinking about it to no avail, Gu Feng also said his thoughts at this time.

"Well, I hope I can find something. ”

For Gu Feng's words, Qin Yuyan also agreed loudly at this time, after all, in her heart, she was also extremely curious about this desert island space.

And a very real problem is that the two of them definitely can't stay here forever.

Even though there are no trivial matters of the sect here, there are no dark tricks.

Although the two are accompanied by each other, and life here is extremely comfortable, there is no doubt about one thing.

One day in the future, the two of them will definitely want to leave.

After all, the Demon Continent was where they really should live.

Even she didn't have to ask Gu Feng, because she knew very well that Gu Feng had the same idea as her.

In other words, Gu Feng's pursuit of martial arts is definitely stronger than her!

The two of them also have the same intuition, and the day they leave here, although it is still a little far away, it is definitely not an unattainable existence.

......

"Let's go?"

Calling softly to Qin Yuyan, Gu Feng also stretched out his hand to her at this time.

Smiling slightly, Qin Yuyan also stretched out her hand.

In the next ten days, the two of them once again traveled through the entire desert island space.

From jungles to mountains, waterfalls to grasslands.

The footprints of the two of them traveled all over the desert island space.

At the same time, there are more and more dark red crystal nuclei in the ancient space ring.

I don't know when it began, the two spirit dragons in the dantian in the body have lost interest in this thing.

At that time, Gu Feng was still quite stunned, wondering if these two guys were transgender.

In the end, I found that they really didn't need this thing, and Gu Feng was also happy.

In a short period of time, among the space rings, the dark red crystal nucleus has accumulated more than thirty pieces.

Thinking about it makes Gu Feng quite excited, after all, the energy contained in this thing alone is already extremely huge.

What's more, so much together?

It's just that after this search, the two of them searched again, although they searched the entire desert island space again.

But there are still no substantial discoveries.

In fact, except for a few caves, the two of them didn't find anything.

Therefore, after searching in front of the side, the two were dumbfounded again!
