What? Ultraman is lifelong?

However, in the fourth dimension, there are harmful cosmic substances everywhere. Is there anything that can divert Zero's attention?

"Cero, have you ever thought about eliminating harmful matter from the surrounding universe?" Castor asked.

Zero nodded, then showed an embarrassed expression, "I did try it, but as far as I know, this kind of substance is usually found near star gates, and I no longer need to go through star gates to travel through the universe."

"Oh, no wonder." Gagula showed an understanding expression on his face, "You are the same as Castor. You both traveled through the universe in an 'illegal way', so you have never come into contact with the harmful substances produced by the mutual radiation between universes.

For you, traveling through the universe may be a matter of closing your eyes or lifting your feet, and this actually leads to the fact that although you have many experiences of traveling through the universe, you have never come into contact with harmful substances in the universe. "

Gagra looked at the puzzled eyes of Castor and Zero, thought for a moment, and explained, "It is actually difficult to explain what the harmful substances in the universe are.

However, I can explain from a human perspective what harmful matter in the universe is in the minds of Earthlings.”

"Generally speaking, for humans, the so-called harmful matter in the universe can be divided into cosmic rays, charged particles produced by solar storms, space debris, and cosmic radiation.

Interstellar space may seem empty, but in fact there is a lot of harmful matter, including cosmic rays composed of a variety of high-energy particles, alpha particles, beta particles, ultra-high-energy neutrinos, gamma rays, etc.

Its intensity is several times that of the radiation in low-Earth orbit. People on Earth have long realized that an overly strong cosmic ray environment can kill life forms. "

These harmful substances in the universe in the eyes of earthlings all come from other cosmic phenomena in the universe. Of course, Castor and his body are far superior to humans. These dangerous things for humans may even be beneficial "energy" in their eyes.

However, it is obvious that the harmful substances absorbed by Bruton are not that simple. Bruton, which can connect countless universes in the fourth dimension, is essentially like a "cosmic trash can" of the Openg universe.

By analogy, the harmful matter that Bruton absorbed into the fourth-dimensional universe came from the macro-universe, or the cosmic phenomenon between the multiverses.

These substances are produced by the interaction between various universes. Some of them are directly absorbed by Bruton, some remain in the gaps between universes, and some enter the universe. These are the harmful substances in the universe that Bruton has to deal with in the universe.

Castor and his colleagues are not afraid of the rays in human eyes, but they still feel more or less uncomfortable with the byproducts produced by various phenomena in the universe and between the universes.

Jagger's travel between universes was the classic 'flesh crossing' version, so when it comes to this, he has a pretty good understanding. He said, "Cero, I think you should have used your experience in the universe to deal with those substances. This is not impossible in itself, but their concentration here is too high. You should learn to use other methods."

"For example, light. I know that you Ultramen like to use light 'enchantment', even when dealing with these garbage. However, light is not that important in the gaps between universes, so harmful substances produced from such places are difficult to be eliminated by light."

"However, you and Leo have learned boxing and kicking, so you should be able to get started relatively quickly."

"So what should I do?"

"Just use force to defeat them. The more direct the attack, the more effective it is. I don't think Castor has the ability to do this, but if it were you, you should be able to do it."

"You are still in my body, can you please not speak so hurtfully?" Castor glanced at the Meta Realm, "It's almost time, since there is no way to get out, why don't we give it a try?"

Before Zero could react, Castor directly released the Meta Realm. The three of them were once again in the chaotic fourth dimension. Gagula glanced at Zero and said, "Watch carefully. I'll show you."

Just like what Gagra said, those things that gave Zero a headache, although they were difficult to destroy in his eyes, could still be defeated in Gagra's hands.

He used the giant Snake Heart Sword and his snake-like sword skills to move back and forth among the messy and unknown objects.

Then, the objects and energy that were originally gathered together were seen to disperse on the spot like crushed dust.

Jagger chopped like this for a while, then turned his head to look at Cero, "Hey! Cero, I know that the two head emblems on your head can also be used as weapons. Try to see if you can cut these things into pieces with pure cutting."

Of course, Gaigula knew that Cellona inherited the head mark from Seven, but just like the other attack methods of the Ultraman clan, when Seven used the head mark, they would often use telekinesis to mix light particles into it, or simply use it as a weapon in conjunction with light, without any other rules.

Therefore, when Gagra demonstrated the Snake Heart Sword before, he actually taught something more or less.

"In theory, the Snake Heart Sword cannot be handed over to others casually. However, if it is you, you should not be short of a sword technique. However, you must remember that you owe me a favor."

Before Zero could speak, Gaigula spoke first, "I will not hold this favor in reserve to threaten you in the future. I hope you will promise me one thing right now. If Haruki reaches that point in the future, he will have to choose whether to be a human or an Ultraman.

If that moment really comes, I hope he can at least retain the right to live out his life as a human being."

Castor looked at Gagra, and Gagra also noticed Castor's gaze, but Gagra didn't say much. Instead, he started the work of "garbage removal" with Zero.

Castor looked at Gagra, who chose to teach Zero a part of the Snake Heart Sword for Haruki, opened his mouth, and then whispered, "Maybe, my previous judgment was wrong. It's not that you learned something on Earth, Gagra, on the contrary. It may be because of you that the Earth will wait until Zeta and Haruki 'evolve' to the final moment."

Sighing, Castor felt that he seemed to be led by Masaki Keigo and had some "great human chauvinism". Maybe humans are really great, great in every aspect.

But in fact, what Gagra got from humans, he has already given back in his own way.

Human beings do have unlimited potential and an irresistible charm. Even the worst people have a rare "brilliance" that belongs to humans in the universe.

However, although these things are indeed important, they may not be that important.

For a guy like Jagger, he may never be able to fully understand what humans are like, but when he is willing to trade with Zero for humans, he already has the radiance of "maternal" that is rare even among humans.

The harmful substances in the surroundings were cleared away little by little. When the harmful substances began to disappear, the true fourth dimension finally appeared.

Although it was still very dark and I couldn't see everything around me directly with my eyes, I could see some things, such as the various pipes connected together in the fourth dimension, which seemed to go against the logic of reality, just like Bruton's organs that seemed to be interconnected.

It was like countless Möbius strips connected together. Castor now finally understood why the previous road was so difficult to walk on, because here, the end of the road is not necessarily the real end, it may also be the starting point of everything.

Castor was watching this scene, and he suddenly thought of something. He was very curious whether Masaki Keigo could still maintain his "great human idea" in such an environment.

In addition to Masaki Keigo, he also thought of another person, that is Tregear.

He wondered, in a place like this, would Tregear still maintain his usual pride?

Thinking of this, he walked to the side of Zero and Gagra and whispered something. After a while, Zero and Gagra looked at Castor with a strange look at the same time, "Are you sure? Do you really want those two guys to come here to clean up the space garbage?"

"Shouldn't it? I won't talk about Tregear, but who can guarantee that his actions didn't affect the production of harmful substances in the universe?

And Masaki Keigo, that guy was supposed to come here, but I let him go to Earth first."

"Of course, I still need your help. For example, you can compete to see who can clear the cosmic garbage faster! Don't you realize that this kind of behavior of clearing cosmic garbage is environmental protection! It is to protect the universe!

As far as I know, you people from the Land of Light should be considered relatively less extreme environmentalists!"

"Well, if you say so, there is no problem, but I still think that competitions are..."

Even Zero, who is always easily excited, felt that Castor's suggestion was a bit outrageous. He didn't understand how the story had come to this point.

Castor didn't intend to give Zero time to think. He looked at Gagra who had been silent, then looked at Zero, and suddenly nodded, "Oh~ I forgot, Zero, you learned the skills to deal with these things from Gagra. You think you can't beat him, right?"

"How is that possible!? I am Zero! Anyone who wants to surpass me is 20,000 years too early!! Even in environmental protection!!"

In fact, this is not Ultraman Zero being sarcastic. In comparison, Castor thinks it is more likely that Ultraman Zero prefers to use this rhetoric to show his confidence. However, inevitably, Gagra's expression changed, and Castor took the opportunity to say, "Then I understand, Ultraman Zero, you must be adhering to your philosophy of life and letting Gagra go, right?

After all, you know that Gaigula is prejudiced against Ultraman. "

Subconsciously, Zero looked at Gagra. It would have been better if he hadn't looked at him. After looking at him, Gagra's defense was broken. He turned around and rushed directly towards those harmful substances in the universe, "This is too much! You Ultramen are like this! Hypocritical! Arrogant! Pretentious! And you can't even tell what is good! What is bad!! "

The Snake Heart Sword couldn't even be called a 'snake' at this moment. Gagra waved the sword like a legendary 'dragon'. The sword style that was supposed to be used for assassination turned into a bold and aggressive fighting style. Amid the sword flowers, Gagra's roar was heard, "Cero! How long are you going to wait! If you have the ability to beat me! Let me see what Ultraman's fighting style is!!!"

"Castor! Don't interfere! This is a battle between the Ultra Clan and the likes of us who are looked down upon by them!!"

"You are asking for trouble!" Zero instinctively confronted Gagra with words, and then, when he reacted, he knew that he could no longer retreat. He didn't know what was going on, but he was dragged into a cosmic-level environmental protection competition.

Looking at the culprit Castor, Zero's eyes were full of vigilance and suspicion. In front of Zero, Castor just shrugged and said, "You see, your instincts can easily get out of control? You're welcome. This is a small lesson I'll give you."

Zero felt his head buzzing. He was not familiar with Castor. Apart from the inexplicable "uncle" feeling, he had no idea what kind of person this guy was.
