Xue Jun nodded slightly, this truth is very simple, just like an instrument, the more sophisticated, the higher the scientific and technological content, the more precious it is, and the cosmic spar is naturally no exception!

"Since the cosmic spar can be refined by a fifth-level life, why didn't the Pioneer Mussel refine it?" Xue Yu thought of another question: "Could it be that he also just got this cosmic crystal?" ”

"Possibly! However, I even felt that he couldn't refine this cosmic spar at all, so he stayed until now! Manta thought for a moment and said in a somewhat affirmative tone.

"Can't be refined?" Xue Yu was puzzled again: "He's a fifth-level extreme life, why can't he refine it?" Didn't you just say that a fifth-level life can be refined? ”

"Hehe, do you think the cosmic spar is so easy to refine?" The Barbarian Tower shook his head and said, "The refining of the cosmic spar is quite harsh, and not all fifth-level lifeforms can be refined!" ”

"Any requirements?" Xue Jun asked.

"If you want to refine the cosmic spar, first, you must at least have a superficial understanding of the origin law of the universe, because the cosmic spar is a combination of laws, if you don't have a basic understanding of the law, it is equivalent to a primary school student reading a college textbook, and you can't understand it at all.

Second, the laws you comprehend must be the same as those contained in the cosmic spar, at least, some of them must be the same! ”

"I can understand the first one, but does the second one mean that if the law I comprehend is the law of space, and the law contained in the cosmic spar is the law of gravity, I can't refine it?"

"That's right! That's what it means! Manta affirmed.

"Well, that's harsh!"

Xue Jun shook his head, looked at the cosmic spar, and his eyes became hot: "I don't know what laws this cosmic spar contains, can I refine it?" ”

"I advise you not to have this in mind, it will ruin you!" The Brute Tower immediately stopped.

Xue Yu looked at the barbarian tower puzzled: "Why?" ”

"Because by refining the cosmic spar, it has evolved into a sixth-level life, which has extremely serious drawbacks!"

Manta said very seriously: "Refining the cosmic spar and controlling the cosmic laws in it is like reading a book, just understand the content of the book, it's very simple and convenient, right?" ”

"That's right! It's really much simpler! ”

Xue Jun nodded slightly.

"It is precisely because it is too simple, so after refining the cosmic spar, it will become extremely difficult to continue to comprehend the deeper laws of the universe, very difficult, that is to say, if you want to go further, it is basically impossible!"

The Brute Tower said in a deep voice: "You remember, any sixth-level life that evolves by refining the cosmic spar basically has no advanced potential, and its strength will stagnate forever!" ”

"And this downside?" Xue Jun was taken aback, this was too scary.

"That's right! Everything has a price, and although refining the cosmic spar is good, it also further cuts off the hope of advancement! The Brute Tower said very seriously: "Generally, fifth-level lifeforms with mediocre talents and hopeless progress to sixth-level life, it is just enough to refine the cosmic spar, but you are different, you are extraordinarily talented, you must not take advantage of this small advantage and ruin you!" ”

"I understand, Brute Tower, don't worry, I won't refine it!"

Xue Yu nodded heavily and reassured.

"Keep it, when you evolve into a sixth-level life, this cosmic spar will be used to enrich your world, and at that time, it will be the most useful!"

After the Barbarian Tower finished speaking, he threw the cosmic spar over, and Xue Yu reached out to take it and threw it into the Neutron Battle Star!

At this time, the flying saucer was sailing rapidly, and after a while, Xue Yu sat in the control room, taking a short rest, and sorting out the information he had just received.

Sixth-level life, perfectly manipulated antimatter, and at the same time opened up a simple and monotonous world in the soul crystal nucleus, and had a very deep understanding of a certain origin law, and at the same time, because of the opening up of the world!

And the world is space!

Therefore, through the comprehension of the world, the sixth-level life also has a very deep understanding of the laws of space!

Sixth-level lifeforms, which are rare in the universe, are quite rare existences, and they are powerful enough to support a cosmic empire, the cosmic empire, which is a vast star field of a galaxy cluster.

All in all, the sixth-level life, very powerful, very powerful, there is no doubt about it!

And if you want to evolve into a sixth-level life, there are only two ways to go: comprehend the Origin Law and refine the cosmic spar!

Therefore, there are generally two kinds of sixth-level lifeforms in the universe: one that evolves by itself, and the other that evolves by refining cosmic crystals!

In general, those who evolve on their own have much higher potential, and those who refine cosmic spars are even worse.

As for the specific strength, it's hard to say, it still depends on the specific situation!

"The second vassal state has arrived!"

Just as Xue Yu was thinking about these things, the voice of the Barbarian Tower rang out.

"You wait here, I'll come when I go!"

Xue Yu got up, then disappeared into the flying saucer, and half an hour later, returned safely.

"Let's go, go to the next vassal state!"

Xue Jun said lightly, and then continued to sit down and rest.

"Nothing to gain this time?" Manta asked casually.

"Nope! No cosmic hedron found! Xue Yan shook his head.

The Brute Tower pursed his lips and snorted, "Normal! If cosmic spars are so easy to obtain, then it's not normal! ”

"The ...... of the next vassal states"

In this way, Xue Ju and the Barbarian Tower roamed the territory of the Pioneer Herder Empire, hunting the fifth-level lives of various vassal states everywhere, and for a while, these vassal states were defeated.

First the borders of the empire, then slowly extended inward, and in just one day, they visited 20 vassal states.

In other words, there are as many as 630 fifth-level lifeforms who died in Xue Jun's hands!

And so many fifth-level lifeforms, all of them were devoured by Xiao Lu!

"In one day, I have hunted so many vassal states, and it will take half a day to kill the remaining 300 fifth-level lifeforms, and at that time, the Pioneer Herder Empire will become an empty shell!"

Xue Yu leaned back in his chair with a smile on his lips, this time, he wanted to completely dismantle this empire, clear the obstacles and threats for the Golden Dragon Empire, and ensure that after he left, the Golden Dragon Empire could operate safely.

"Destroy the small ones first, and then destroy the big ones, the pioneer insect herder empire, sooner or later it will be in the pocket of my Golden Dragon Empire!"

"You're too hard, but I like it, quack!"

The barbarian gaggat laughed.

ps: Finally, I recommend the old book "Galaxy Domination" of the black cat, which is also a science fiction article of the same type, 2.88 million words, brothers and sisters who are short of books can take a look, hehe!
