There were not many fifth-order people, only a few dozen people left, Xiao Mu didn't say anything more, and led people to the outside of the ruins.

It was dark at the bottom of the sea, but the aura emanating from the crowd was enough to illuminate some areas.

He swept his mind first, and there were thousands of alien races in front of him, most of them were the Water Spirit Rhino clan or subsidiary races.

They have the natural power of water attributes, and they are naturally affinity with the power of water, so the fourth-order water spirit rhinoceros can also move relatively freely at a depth of 10,000 meters under the sea.

In addition to the Water Spirit Rhino Clan, there are also the Wood Spirit Clan and the Three-Eyed Giant Spirit Clan, all of whom are doing things nearby, seemingly digging in the dirt, presumably to expose the ruins as a whole.

It's just that the soil on the bottom of the sea is harder than steel after being crushed by the seawater, and it is very difficult to dig even for aliens.

"The relics that can be preserved at a depth of thousands of meters at the bottom of the sea are also sixth-order, or even higher!"

Xiao Mu's eyes lit up slightly, and he wanted to reach the bottom of the sea, wanting to see what this ruin was.

Soon, his face became strange, there were many cracks here, it should be cracked by an earthquake or something, and under the cracked seabed, there was a behemoth.

It didn't look like a mythical relic, but rather a large black man, over ten kilometers long, made of apparently metal.

In terms of appearance, it looks a bit like a battleship, rather than some mythical relic.

"Could this be a kind of warship?"

Xiao Mu frowned, if this is the case, this is the remnant of a technological product, and the type is completely different.

Judging from the size of this warship, a warship of more than ten kilometers can still be preserved at a depth of 10,000 meters, and if it contains a level of science and technology, it should far exceed that of today's human beings.

At least, as far as he knew, even if human technology could build such a large warship, it would definitely not be able to preserve it at a depth of 10,000 meters.

After all, human technological weapons now threaten at most the third order, let's just treat it as a fourth-order technology, and want to keep it at the bottom of the sea, and it has not been corroded for so many years, let alone the fifth-order level, right?

It's just that how can there be such a high-tech warship on the earth that is obviously beyond the level of human beings, could it be that it is left by aliens or previous scientific and technological civilizations?

With doubts, Xiao Mu appeared among the aliens, and the golden light emitted from his body instantly illuminated the vicinity.

"Who!"

The alien race suddenly felt a great pressure, and this pressure enveloped the entire trench, making their hearts tremble and their hearts were surprised.

"The one who killed you."

Xiao Mu didn't have much nonsense, taking advantage of the fact that the alien race was affected by the strong light, he raised his hand and waved it, and the dense sword element condensed out, and then spread out, purposefully attacking the alien race.

Puff puff!

In the midst of the shattering sound, blood holes appeared on the bodies of the alien races, and the shield could not block this attack at all, and the knife element entered the body, destroying their vital points in the blink of an eye, and killing them.

With just one breath, hundreds of alien races in the vicinity fell, and because of the pressure here, many corpses were directly flattened by the sea due to the loss of strength.

"Who are you, aren't you afraid of our revenge?"

The leader who took the lead shouted angrily, and what answered him was a sharp sword element, and then he stepped into the footsteps of the alien race who had died just now.

This was just the beginning, Xiao Mu's hand raised and fell, and the dense sword yuan flew out, easily killing the alien race.

The difference in strength between the two sides was too big, even the fifth order was slaughtered in front of him, and all the alien races did not hesitate to choose to flee after realizing Xiao Mu's terribleness.

It's a pity that their speed is as fast as Xiao Mu, and they will be killed if they can't escape far, even if they escape one step earlier from a long distance, they will be solved by other human masters in the nearby seawater.

In less than a stick of incense, thousands of aliens were killed, and only two were left, ready to be used to inquire about the situation.

"Tell me what you've found here, and if I'm satisfied, I'll be able to live."

Xiao Mu said lightly, there is no doubt.

"We didn't find it for a long time, and we haven't opened it yet!"

The alien on the left shuddered.

"Yes, yes, we don't know what's going on inside, the pressure here is too high, it's really open."

Another alien followed.

Xiao Mu thought to carefully probe again, the submarine battleships have indeed not been dug out yet, these alien races do not understand technology at all, and they should not have been opened.

"It doesn't provide any useful value, so let's die."

Popping out two fingers, the alien was killed on the spot before he could say anything.

"Dispose of the corpse."

Ordering the others to act, Xiao Mu landed on the battleship, and with a slight stroke of his hand, the soil on the surface more than ten meters thick was cut, and with a slight shock, it fell to the side.

Black metal appeared in front of him, knocked on it, made a slight sound, and then with a stroke of his finger, a string of firelight appeared,

"Hey, the hardness is so high."

Looking at the metal that didn't even have scratches, Xiao Mu showed a look of surprise, the moment he landed on the spirit gold just now, it could be cut directly.

The knife yuan condensed in his hand, slashed out fiercely, and with a ding, a faint trace appeared this time, but in the next second, this trace quickly disappeared, obviously memorable.

"It's not simple, it can survive at a depth of 10,000 meters, and the hardness itself cannot be low, but it still exceeds my expectations."

Xiao Mu narrowed his eyes, and a knife appeared in his hand, this was the Ring Ring Knife he had refined, and its power was much higher than before.

Injecting strength, the Ring Blade lit up, and he slashed at the battleship in front of him, this time successfully sinking into it, but it was obviously stuck.

If he wants to completely break it, it is a little difficult for him to estimate the full strength, the material of this kind of battleship is comparable to immortal material!

Xiao Mu exclaimed, although the material of this battleship does not have any immortal light, but the material is definitely comparable to immortal material, which is the crystallization of science and technology, not the material naturally formed by the environment.

Being able to produce this material by science and technology, the level of science and technology contained in it is a bit terrifying, and I don't know if it's a blessing or a curse to take this thing out by myself.

He is worried that there are some technological threats in it, such as very powerful artificial intelligence, which in turn invades the superbrain of human beings, and is likely to complete great damage.

But if not, the technology contained in this battleship is obviously very valuable, and it may not be much worse than the mythical civilization, even if it is not as good as the top mythical civilization, it is still possible to create a weapon that threatens the sixth order.

And this is enough to make human science and technology advance by leaps and bounds, so as to keep pace with the cultivation civilization, and in the future, human beings will have one more powerful means.

Thinking of this, Xiao Mu's face changed for a while and finally decided to take it out, but he had to arrange a formation to isolate it first, so as not to have any impact.

"Now the formation materials are not enough, let's leave them here first, or just lay out the formation here, make a research base, and study the technology in it little by little."
