Ultraman cubs begin to wreak havoc.

No, no, wait, this isn't right...

Tartarus, somewhat bewildered, clutched his head, trying to sort out his thoughts. This had all happened so suddenly; one second they were laughing and joking, the next it was goodbye forever. This was too... too... Calm down, calm down, Tartarus. You are the ultimate life form, the warrior of the Absolut, Absolut Tartarus! How could you lose your composure like this? Think about it, how could someone not even control the speed of transformation? You're not a child..."

At this thought, Tartarus's train of thought suddenly stalled. He glanced at the floating white light, then slowly grabbed his head with both hands. At that moment, he felt his soul screaming, because this 'Hak' really was a child!

"This is impossible! This is impossible! Think of something! Think of something!"

Tartarus suddenly stood up, raised his hands, and guided the red gems in his hands to glow, opening the Narac Space. This space could not only be used as a warehouse, but also open interdimensional portals to various timelines, allowing for time travel and free movement between parallel universes and the real world.

Of course, Tartarus is not going to a parallel world now, but to travel through time in this universe. He wants to go back to the point in time before 'Hak' was transformed to stop this silly kid's adventurous behavior.

However, just the thought made Tartarus clutch his chest and collapse to the ground. Traveling through parallel worlds and traversing the timeline of this universe are two completely different things. The complexity of the latter and the price to pay are far more terrifying than the former. Now that he is severely crippled, he is naturally completely unable to perform such an operation.

"...It feels like a dream."

Tartarus lay on the ground, gazing at the vast universe, and murmured as if in a dream, "That child named 'Hak' is like the star you see now. While you are still immersed in the beauty of starlight, you don't know that it is the light of a long time ago, and its true form may have been destroyed long ago."

"This encounter was something I didn't want to happen, but I couldn't bear to miss. This trip has truly broadened my horizons."

Tartarus stood up, cradled the now stabilized ball of light, and carefully placed it into the Narac space. Then he headed towards his home planet. After healing his injuries, he would follow Hack's advice and go find Justice. The Ultra Warriors... it was time to get to know those busy Ultramen and see what kind of beings they really were.

As Tartarus set off, Subaru recovered. Just like when he had given all the light to Jugglus Juggler, after converting all the light into primordial pure white power, Subaru's consciousness immediately returned to his body and he fell into an extremely weak state.

but!

Now, next to Gen Subaru's room is a warehouse, which is full of energy-generating stone statues. He can replenish his energy with just a thought. In addition, his current physical condition is much better than before, so there is no need to take him to the medical department for emergency treatment.

There was a reason why Yuan Mao was in such a hurry to come back: his data terminal was vibrating and beeping wildly, which was the reaction to an emergency notification. The boy wiped the cold sweat from his forehead, picked it up and saw that it was a message from the TLT-J Energy Experiment Department. Without even changing his clothes, Yuan Mao hurriedly got up and ran over.

Then, just as he ran there and pushed open the door, Mitsuhiko from the nearby cave excitedly hugged him and spun him around. Seeing the joyful expressions on everyone's faces, Subaru immediately realized something and exclaimed in delight:

"Did you make it?"

"Ah! We did it! Subaru!"

Mitsuhiko Ishibori said happily:

"With the technology you previously provided and the assistance of our visitors, we have successfully overcome the problem of shrinking the energy of the stone statue!"

Previously, Matsunaga Yoichiro had said that the shrinking gun could shrink the stone statues to make them easier for Subaru to carry. However, in subsequent experiments, it was discovered that although the shrinking gun could indeed shrink the stone statues, it would also cause inexplicable explosions.

Subsequent investigations revealed that the energy within the statue could not be compressed after it was shrunk, causing it to violently break through the seal and trigger an explosion. Therefore, this energy compression issue has become a new challenge.

But now, this problem has been successfully solved. As long as Subaru conducts a practical test and can draw sufficient energy from the shrunken statue, then...

"Mr. Prospect! Mr. Prospect!!"

However, amidst this joyful atmosphere, a sudden, urgent call arose. Subaru, who had been put down, jumped onto the table, crossed the crowd, and saw a middle-aged researcher lying on the ground, with others giving him first aid. The boy quickly released pure white light, transmitting it into the researcher's body, and then carried him to the emergency room.

However, the result did not change. After all, the pure white light itself does not have the ability to heal, a fact that Gen Subaru had already tested on Saijo Nagi.

“Subaru, look, Mr. Seishiro is leaving with a smile.”

Ishibori Mitsuhiko, who arrived later, saw that the somewhat dazed Minamoto Subaru had just arrived. He gently patted the child's shoulder and said in a low voice:

"Mr. Shiro Kengo already had a serious heart condition, and with such intense research work, his sudden death was to be expected."

"Since you know that, then why..."

"Because he is an authority in this field, and... listen."

Mitsuhiko Ishibori knew what Subaru Minamoto was about to say, interrupted him, and tapped the terminal on his wrist a few times, playing an audio clip. The voice was clearly that of Shiro Kenjiro:

"Subaru, if you hear this recording, it means I've already collapsed in the lab. I don't know if I've finished my research or helped you by then, but no matter what, please don't be sad. As a researcher, the lab is my battlefield. Falling there is a worthy death for me, and I feel honored."

"And Subaru, I also want to thank you. Thank you for bringing that advanced knowledge, which allowed me to find new directions for progress. 'If I hear the truth in the morning, I can die content in the evening.' I have no regrets. Well, I've said what I wanted to say, and I've said quite a bit. Let's end it here. Subaru, my young comrade, take care."

As always, Makoto Shiro's tone was as forthright as ever, just like when he would tell Makoto Shiro stories about world history whenever he had free time. Minamoto Subaru didn't say much, but silently covered Makoto Shiro with a white cloth. From then on, there was one less person he knew in this TLT-J.

However, there's nothing to be sad about. Although my physical condition has improved, my lifespan doesn't seem to have increased much. At most, I'll be able to go down and reunite with them in a few more years. I just don't know if the underworld on Earth will accept the soul of an alien like myself.

123 Subaru: Taiga, it's you again?

"Let's go, Ishibori-kun, let's test how much energy conversion efficiency the successfully miniaturized stone statue can achieve."

"Well, okay, let's go."

Subaru and Mitsuhiko Ishibori turned and headed toward the new experimental site. After all, this statue was no ordinary one. The statue separated from the young Nexus was alright, but the statue of the young Nexus clone was really powerful when it exploded. Just look at the huge crater and rift that were blown up at the Bear Branch.

Therefore, without Subaru's involvement, all the stone statue tests were conducted at a new testing site, which was originally a special safe room used to preserve the spark of human civilization in case of emergency. Of course, even there, only the stone statue of the young Nexus could be used.

This also means that TLT's researchers need to have a certain level of confidence every time they conduct a shrinkage test. After all, the Childhood Nexus statue was an early product of Subaru's testing of the seal's strength. Once he mastered the statue sealing technique and ensured that it wouldn't be easily broken, Subaru went straight for the Youth form Nexus statue. As a result, the number of Childhood statues is relatively small.

"Oh right, there's something I forgot. Ishibori, you go ahead, I'll go find the visitors."

At that moment, Gen Subaru suddenly remembered something. After saying something to Ishibori Mitsuhiko, he hurriedly headed to the deepest part of TLT-J, which was the location of the 'Wangchuan', to find the visitors and deal with the time-space teaching materials he had just received from Tartarus.

Although Tartarus suggested learning everything, given his lifespan, Subaru could only ask the visitors to think of ways to extract methods to free up storage space.

When Gen Subaru appeared at the deepest point, he saw the jellyfish-like visitors busy with something, most of them emitting a ghostly glow, and strings of data flashing rapidly on the machines next to them. Gen Subaru was momentarily unsure whether he should greet them.

"You came."

Meanwhile, on the other side, several visitors floated up and greeted Gen Subaru. However, their appearance made Gen Subaru feel as if they were overtime workers who worked late into the night every day and were woken up by their alarm clocks in the morning, reluctantly getting up.

"Subaru, is something wrong?"

One of the visitors, who had floated up, looked at the child in front of him and asked softly. Although they needed a 'vessel' to relay their messages to humans, this was not necessary for Subaru, who had exceptional telekinetic abilities.

"Here's the thing, sir, please take a look at this."

Yuan Mao took out the Ark Bracelet, transmitted the data inside to the visitors, and also explained his needs.

"Well... what they said is right. You'd better learn it yourself. It's a theoretical system; if you take it out of context, it's like a hanging garden in the sky..."

"The Light of Nexus belongs to Lord Noah's power faction."

At this moment, the visitor next to him seemed unable to listen any longer and leaned out, saying to the companion who was talking to Gen Subaru:

"In terms of control and performance of spacetime forces, it shouldn't be too bad. Although I can't learn all the knowledge, imitating the activation principle of a space machine shouldn't be a problem."

"Yimi, you can't say it like that. The power of space and time is very precise. If you don't learn the basics clearly, what if there are problems in the process?"

“Tatami, don’t be so idealistic. You have to look at the current situation. Are there conditions that allow you to develop and learn slowly? We have to start from reality.”

'Job's tears', 'tatami'... these seem to be nicknames that visitors gave themselves after arriving on Earth. According to them, it was to better communicate with Earthlings. However, Matsunaga Yoichiro and others thought it was because they found it more fun. But whatever their purpose, it certainly made them easier to address each other.

According to Kira Sawa, if you were to try to memorize their real names, it would probably take Minamoto no Subaru a month to remember them correctly.

"You also need to consider the upcoming battle situation. If the enemy suddenly appears and Subaru needs to engage in space warfare to relocate the battlefield, can you really let him learn slowly?"

"I understand the principle of Job's tears, but..."

Just as the two visitors were arguing, Gen Subaru suddenly raised his hand, cautiously interrupting them, and tentatively said:

"Um, I heard Mr. Matsunaga mention before that there's a brain-computer interface that can achieve high-speed learning. Could you tell me about it...?"

As soon as Minamoto said that, Yimi and Tatami fell silent. Minamoto was watching the changes over there, but the visitors were only in the form of jellyfish, so his expression was not visible.

"I can consider it, but..."

At that moment, a jellyfish floated out from among the visitors who were working, picked up the conversation, and said softly:

"The level of technology on Earth is not yet at the level of our civilization. If we want to achieve data transmission through brain-computer interfaces, the process will be quite painful."

"I've never been afraid of pain or anything like that."

Subaru answered firmly, and the visitor nodded and said softly:

"In that case, I will go and inform Matsunaga Yoichiro to prepare the relevant equipment. Once the equipment has arrived and the relevant knowledge has been compiled, someone will contact you."

"Okay, that's troublesome."

After saying that, Gen Subaru bowed slightly to the visitor in thanks, then turned around and bowed to the barley and tatami mats before leaving.

"Pigeon, are you really going to do this?"

After Gen Subaru left, Tatami immediately asked about the brain-computer interface. The visitors were all aware that, given Earth's current level of technology, it was impossible to manufacture a device that could serve as a brain-computer interface.

Therefore, if this operation is to be carried out, the visitor can probably only act as the core of the transfer and buffer. If all these spacetime theoretical systems were transmitted to the past, the visitor, as the transferor, would probably fall into a state of silence for a considerable period of time, or even die directly.

"Don't you feel great right now? Everyone is working towards the same goal, just like when we joined forces to rebuild our home after the alien beasts were defeated."

Looking at the River of Oblivion beside him, the pigeon said with some emotion:

"And... the Light of Nexus and the civilization it inhabits advance hand in hand... Haha, isn't that close to our dream back then? It's just a pity that the 'light' we created unfortunately fell into darkness."

"Now that you mention it, it seems like not much time has passed."

The pigeon's words stirred up memories of the past for Yimi, who murmured wistfully, plunging all the visitors around her into silence.

"Our story has temporarily come to an end, but I believe that everyone here may be able to rebuild our civilization in the future, but for now..."

The visitor, a pigeon, said with a carefree air:

"Zuo Mu, Kargalovsky, Robert Barth, Shiro Makoto... these outstanding anthropologists have given everything for their civilization. Their sacrifices were not in vain; their lives have become the ladder for the continuation of the entire race."

The pigeon visitor gazed at the shimmering River of Oblivion, paused as if recalling something, and then continued:

"I... want to see what path the civilization on this planet will ultimately take, and I also want to see what kind of light the Light of Nex will ultimately shine. So, I want to help them a little more. Okay, let's stop the small talk here. Yimi, Tatami, and everyone else, come and help me out. Even I find these spacetime theory systems a bit difficult to understand."

Just as the visitors were working together to sort through the knowledge bestowed by Tartarus, Gen Subaru encountered an unexpected person in TLT-J: Kobayashi Rin, the priest whose house was being used by Pigmon.

Noticing Subaru's surprised look, Priest Kobayashi smiled and waved his hand, understanding what the boy was surprised about. He took out his work ID from his pocket and said softly:
