Luo Yu's attitude towards the demise of a low-level civilization can be said to be indifferent, if it weren't for Lei Luoduo to ask, he might not have bothered to explain, just like humans don't care about the life and death of ants.

This mentality is very much in line with the nature of Luo Yu's work, but ......

Even if his strength is already at the same level as that of the Sweeper, Lei Luo can't treat all beings like ants after all, watching a world similar to his previous life be destroyed, even if the surface is still calm, but his mood is actually very unpleasant.

For the rest of the journey, the two didn't talk about anything more.

A week later, in an empty cosmic area, Lei Luo unconsciously stopped his steps, looked at the distant scene, and lost his mind for a while: "Is that the land of the Big Barrel Wood Clan?" ”

The huge black star stands in the void, giving people a cold, secluded atmosphere, and on its periphery, surrounded by countless islands, large or small, far or near, like countless moons, emitting bright light and slowly floating.

Black star, plus islands, is almost the size of a solar system.

Once upon a time, a similar celestial object that he had seen by chance flashed through his mind, and Lei Luo immediately recognized the name of the pitch-black star, which was undoubtedly the "neutron star".

What is a Neutron Star?

When a massive star burns all its fuel, its central region begins to collapse due to gravity, followed by a supernova explosion, blowing up the outer layer of matter.

In the process of gravity collapse, it is possible to form planets composed almost entirely of uncharged subatomic particles, neutrons, which have a mass of about 1.4 to 2 times that of the Sun, but are only a dozen kilometers in diameter.

Neutron stars are one of the several death states that stars can be born after supernova explosions, and correspondingly, there are black holes and white dwarfs, and their existence forms can be summarized as "semi-collapsed states".

The microscopic substance that makes up neutron stars, called neutron states, or element 0, is extremely dense, and the mass of a sugar cube is equivalent to the sum of human mass, so you can imagine how strong its gravitational pull is.

The neutron star in the distance is many times larger than an ordinary neutron star.

Lei Luo thought to himself, if his prediction was correct, the Big Barrel Wood Clan should have used special means to limit the gravitational pull of the neutron star, otherwise the surrounding islands would definitely be torn apart by gravitational waves at the first time.

Instead of being like a satellite orbiting the Earth, as it is now.

"Gone."

Luo Yu greeted and flew forward first, Lei Luo didn't have time to think about it, and hurriedly followed, closing the distance, and observed some details: each island has a dark green branch extending out of the surface of the neutron star.

The dense branches of the trees, along with the islands orbiting the neutron star, move together, this scene, like a gently fluttering spider web when the breeze blows, makes the scalp tingle to watch.

Following behind Luo Yu, Lei Luo crossed the islands, avoiding the strangely shaped, thick branches, and he glanced left and right, and saw the houses, palaces, and the large barrel wood people built on the islands.

Each island is like a different space, a small world, and the soft light shines through from the core, illuminating the various scenes on the surface, where there are forests, rivers, hills, snow, deserts, and some ......

It's not easy to describe for the time being, the natural environment.

Luo Yu glanced at Lei Luo, who was looking left and right, and said lightly: "The unique scenery on those islands is all created by the chakra fruit, and without the natural energy contributed by other planets, this place would not be so habitable." ”

"Chakra fruit?" Lei Luo turned his head and wondered, "Isn't that thing for food?" Do you mean that those who have eaten the fruit have the ability to transform nature? ”

"No, it's not like that." Luo Yu shook his head and explained in easy-to-understand language: "The chakra fruit, for my clan, is the basic unit of energy, and in your understanding, it should be equivalent to batteries and gasoline. ”

"By plundering the energy of other planets, the chakra fruits collected can be transformed into a medium to expand our territory through specific devices, and most of the inhabited islands are born in this way."

"Of course, chakra fruits can also be eaten, but under normal circumstances, not many people do this." Speaking of this, a hint of disapproval flashed in Luo Yu's eyes.

"Oh? Why? ”

Luo Yu pointed to an island not far away, where there was a group of big wooden children standing on the high mountain, looking curiously at this side, and he said, "Most of the clansmen will never leave their place of residence for the rest of their lives. ”

"Living in the clan land, you don't need too high combat effectiveness, even if you go out once in a while, with the power of blood, weapons, and spells, it is enough to deal with the natives of low-level civilizations, and high-level civilizations ......"

After a pause, a trace of remembrance appeared on Luo Yu's face:

"If you have enough talent, self-motivation, and want to become stronger, then you can become a true warrior by challenging the trial of the Vishnu Protector at the age of two hundred."

"So as to completely widen the gap with the low-level clansmen."

Lei Luo noticed the change in Luo Yu's expression, and had a realization in his heart, feeling that the other party should have grown up to this day through this channel, and maybe the other three cleaners should be the same.

"However, there is only one chance to challenge, and if you fail, you will prove that you are not talented enough to enter the regular battle sequence." Luo Yu shrugged his shoulders and said meaningfully:

"Like the Kaguya you've seen before, Cixian are people who are not qualified to become warriors, but they are not willing to stop here for the rest of their lives, so they can only hope for the chakra fruit, trying to produce qualitative changes with quantitative changes."

"Honestly, it's not wrong, it's just a little ...... It's ridiculous. ”

There is never a shortage of careerists in this world, talent is not enough, the number is to make up, and the behavioral motives of some tree planters are generally the same, but looking at the gap between Luo Yu and their strength, it can be seen that this road is really a matter of seeking the near and far.

But there is only one trial in a lifetime...... What can they do?

Kaguya, Cixian, Pushi, Peach, Jinshi, these people's behavior of competing for chakra fruits, in Luo Yu's eyes, maybe fighting for bones with a group of wild dogs, is not much different, right?

A real warrior has long used nuclear energy, and those who can't be a warrior will either have a mediocre life, or they can only become a tree planter, stealing two chakra fruits under the guise of public welfare and using inferior gasoline energy.

No matter how much gasoline there is, where can it compare to atomic energy?

"It's really a strict hierarchy......"

Lei Luo's heart was touched, and he couldn't help but sigh, he thought of the ninja world, thought of those blood ninjas and ordinary ninjas, it seems that no matter where he goes, these things such as bloodline talent occupy a dominant position in growth.

This guy is also a "nobleman", right?
