"I hate it!"

Looking at Mu Chen's behavior, Song Qi couldn't help blushing, and hurriedly buried his head behind Mu Chen.

And the white tiger in front of him also smiled helplessly, but silently accelerated the pace of his feet.

It feels like the tunnels and caves here are all made of a single module, the same pitch black, the same length, the same silence.

It feels like Mu Chen and the three of them haven't really left that base yet.

If it weren't for the fact that the three of them came out of the water because of this, and they were all wet, maybe Mu Chen really had to wonder if he was still in the tunnel leading to that base.

It's just that this time Mu Chen and the others have walked for a long time, but there is no abnormal smell in the air, it seems that this road should still be relatively safe.

In fact, while walking, Mu Chen was still thinking about it, it was also the Ocean Blue Hole, fortunately, there were no particularly powerful creatures in this Ocean Blue Hole, so that the grenades that Qingyu gave himself have not come in handy until now.

Of course, Mu Chen definitely didn't want to encounter the moment when he had to use that grenade.

It's just that Mu Chen also has a little hope to experience the power of this grenade.

It's just that I'm still very happy to easily take away some of the advanced tools of pre-human beings.

Why not?

It's just that Mu Chen doesn't understand why these buildings built by former humans form an ocean blue hole?

Or rather, why did these buildings built by all mankind run under this blue hole in the ocean, even if it was artificially caused by the surrounding landslides, it would not be possible to be buried in such a deep underground.

Perhaps, after the succession of millions of people on this earth, it is possible to bury these objects deep underground, but what is the opportunity for them to just form this ocean blue hole, opening such a large passage to the surface of the sea?

For these ocean blue holes, why did they automatically emerge from the land, and at the same time carry such a terrifying void breath, it is obviously not something that a void core can contain.

There are too many strange places in these places, and Mu Chen now feels that he is becoming less and less familiar with the world he is in now.

However, it is still the same as the previous question of Mu Chen, these are not things that can be thought out at the moment, and the best way is not to think crankily, and work hard to improve your strength.

Moreover, the ocean blue hole may not be as small as it seems.

Maybe there are many, many other places under this ocean blue hole, such as the base that the three of Muchen arrived at just now, but because the ruler of the base of the former human race chose to bury the base, it caused the various areas to be separated from each other by the mud and could not communicate with each other.

If this is really the case, Mu Chen is now looking forward to what kind of scene will be at the end of the tunnel he is walking on.

In fact, Mu Chen felt that it was really a good thing to be able to be lucky enough to enter this ocean blue hole.

After all, the Ocean Blue Hole here is not like the real Ocean Blue Hole on the other side of the earth, although there is no void breath to block it, but it is a random creature on the periphery of the Ocean Blue Hole, all of them have the strength of the Void Period or the Tribulation Period, compared to the Ocean Blue Hole, the Ocean Blue Hole that Mu Chen and the three of them entered is obviously much safer.

But the treasure hidden in this is no worse than the treasure contained in the real ocean blue hole.

What's more, Mu Chen actually met the true incarnation of his nameless sword here, which really surprised him.

Compared with the golden sword he used to have, the real nameless sword he used to do now is obviously much stronger and more handsome.

It's just that the current nameless sword, whether it is on the scabbard, the sword peak, or the hilt, Mu Chen has not found the seventeen seals of his nameless sword.

Although now when Mu Chen is using this nameless sword, he can still sense the seventeen seals contained in it, so as to push and release it.

But when he couldn't see the thirty-four fonts of the seventeen seals, Mu Chen always felt that something was strange.

Maybe I'm used to seeing the font of those seals, but now it's suddenly gone, and I can't get used to this change all of a sudden.

According to what Qingyu said before, the ocean blue hole on the other side of the earth was caused by a huge meteorite hitting the earth, which caused the appearance of that ocean blue hole.

But the powerhouse of the beast clan was in that blue hole of the ocean, and obtained the treasure that previously belonged to the former humans, the core of the void.

The various terrifying and powerful creatures derived from the ocean blue hole in the house Muchen, Mu Chen also speculated that the energy derived from those terrifying and powerful creatures was not only the energy emitted by a meteorite, but also some powerful tools made by previous humans in the ocean blue hole.

When you become stronger in the future, you will definitely have to go to that ocean blue hole to explore.

But......

I am only the cultivation of the merger period now, if I can't encounter any more big opportunities, I'm afraid it's still far too early to be able to go to the lowest cultivation of that ocean blue hole, the Tribulation Period.

Moreover, Mu Chen felt that the 'Thor' mecha in his body, if it was really used to fight against the powerhouses of the Tribulation Period, then the various shells released by the 'Thor' mecha might not be of any use at all, at most, it would become his own armor in disguise, carrying two attacks for himself.

And he put on that 'Thor' mecha, but he can't even use spells, at most, even if he barely summons his nameless sword, but he can't urge the seal on the nameless sword, and when facing an opponent with the same strength in the merger period, Mu Chen can also use the Thor mecha to fight.

But once Mu Chen's strength improves, being such a handsome 'Thor' mecha will inevitably be abandoned.

In fact, what Mu Chen didn't know, according to the improvement of his own strength and the advancement of his cultivation, the void air breath in his body would also become rich, and according to the concentration of the void air breath provided to the 'Thor' mecha, the 'Thor' mecha can also evolve and improve.

Moreover, in the future, when facing the mysterious extraterrestrial civilization, if Mu Chen wants to fight in space, he must cultivate and learn the corresponding spells, otherwise, using the Thor mecha in his body may be a more convenient and reliable decision.

After all, it is also the crystallization of the cross-era high-level technology of the previous human beings, if even these small upgrades and evolutions cannot be completed, then what kind of advanced technology is there to talk about?

With a mind full of questions, Mu Chen quietly led Song Qi like this, and slowly followed behind the white tiger.

This time the tunnel is obviously much longer than the tunnel that Mu Chen walked through last time, although there is no clear tool that can record time, but Mu Chen relied on the biological clock in his body, and estimated that the three of them should have been walking for nearly half an hour, but the person in front of him was the tunnel with no end in sight, and there was no sign of coming to the end at all.

"Shall we rest where we are?"

After walking for so long, Mu Chen could also feel that Song Qi was already a little tired, and he was slightly reezing behind him, so Mu Chen also stopped and suggested to the white tiger in front of him.

And the white tiger also turned his head, looked at Song Qi, who was already a little tired, nodded lightly, and sat down on the spot and closed his eyes to recuperate.

Seeing that the white tigers all agreed, Mu Chen also gently helped Song Qi to sit down, and rested on the cave wall beside him.

At this time, the tunnel was quieter, because there was no footsteps of everyone, and the flame made by the white tiger was not like the usual flame, it would make a 'click' sound, so now the surroundings were a little quiet.

Except for the sound of everyone breathing evenly, there was only the sound of tiny stones tumbling down.

But......

How can there be the sound of falling stones around here?

There are quirks!

When everyone was walking, because of the quiet environment around them, the three of Mu Chen could get down their heavy feet when they walked, so that the surroundings would not look so deserted, and because of this, the three of Mu Chen didn't notice the sound of small stones rolling down from the surroundings.

Then now everyone sat down and adjusted their state quietly, there was no loud footsteps, and the sound of the tiny stone rolling down slowly came and reached the ears of the three Muchen.

Obviously, Bai Hu and Song Qi, who had just sat down to rest, were as tight as Mu Chen, and they were alert to the sound of the tiny stone rolling down, and they all sat upright, leaning against the wall, vigilantly observing the surroundings.

Listening to the direction of the sound, it seems to come from the place where Mu Chen and the three of them walked, and as time slowly passed, the sound of the stone rolling down became louder and louder, and it was obvious that something seemed to be approaching here, but the speed of walking was very slow.

Without Mu Chen's explanation, Song Ci and Baihu understood it, stood up one after another, and continued to walk towards the depths of the cave.

Because, in this tunnel, it is all straight passages, and there is no hidden place around it at all.

And Mu Chen and the three of them didn't know what kind of power the creatures approaching them had.

Therefore, in such a place where you can see each other at a glance, it is definitely not suitable for Mu Chen and the others to ambush that creature.

Therefore, Mu Chen and the three of them should go to the end of this tunnel as soon as possible, and see if there is the same base as just now at the end of this tunnel, or another large space, with a hiding place so that Mu Chen and the others can be fully prepared to deal with the creature that is close to them here.

Bai Hu and Song Qi are not stupid, they both understand the current situation in disguise at once.

Raising the fire ball in his hand, the white tiger also walked in front again, but this time, his pace was faintly accelerated.

Song Qi, who wanted to stop and rest, found an abnormality behind him when he had rested for less than a minute, and had no choice but to continue walking forward.

Looking at Song Qi, who was a little weak, Mu Chen didn't say anything, and directly urged the 'Thor' mecha in his body.

The strength of the mecha is still quite large, I saw Mu Chen grabbing half of the white mecha with one hand, and directly picking up Song Qi with one hand, and running towards the front quickly.

"Me!

And this kind of operation?"

Seeing Mu Chen directly summon the mecha to achieve the purpose of saving effort, Baihu was also surprised, he didn't expect that this mecha could be used for transportation like this in addition to fighting.

But the white tiger is also very helpless, who calls himself no mecha, looking at Mu Chen, who is chasing him quickly, the white tiger also sped up his pace, running in front of Mu Chen, illuminating the surrounding space.
