Black Shirou and White Shirou / The World Five Years Later...

Yuli became a high school student more than ten years later and met Shirou. In order to repay the kindness she had received from him and to acknowledge what Shirou had done, she became Shirou's assistant.

They are here because they traveled through time and space via a wormhole.

As for the relationship between the White-haired Killing God and Shirou, in the end, Shirou and the other should have been one entity before, but now they are two separate entities.

It all started with the awakening of the white god from the depths of the universe. His thoughts began to influence the consciousness clones in various worlds. If they were allowed to manipulate him, then the current White-haired Killing God would be the same as the black-haired Shirou.

The opponent was a controlled clone of the White God after his awakening, just like the White God before his defeat. Shirou, on the other hand, forcibly split his spiritual body in two by fusing with Angra Mainyu at the last moment, thus maintaining his own identity.

The White-haired Killing God represents the will of the white-haired gods. He is active in every era of this world in order to maintain world order.

He developed an incredibly powerful ability to use his unique personality, giving the heroes a significant advantage. Therefore, the villains, who possessed the ability to travel through time, sent assassins to kill Isaka.

Upon receiving the news, Shirou, accompanied by his assistant Yuli, traveled to this world to stop them, rescue Isaka, and incidentally perform some acts of justice.

However, there are avatars of white gods throughout the world, scattered across every era. They eliminate anything that disrupts the world's order, acting as guardians in normal times, but once they confirm that the other party is a harmful insect, they will not hesitate to spray insecticide to kill it.

Shirou and Yuli are not beings of this time; they are clearly outcasts in this world. Therefore, wherever they go, they are inevitably detected by the White Killer and come to stop them.

However, it now seems that even the divine avatar considers Isaka to be someone who must be eliminated.

Shirou conducted some investigation into Isaka, even having a face-to-face conversation and putting him to the test. If Isaka was a bad person, then he left, letting him die.

But at least it was certain that he wasn't a truly wicked person, and now it's 100% certain that since the White God also wanted to kill Isaka, he must protect Isaka.

In this desperate struggle, as Shirou unleashed his Death Wish, his speed gradually increased and his power amplified over time. However, Shirou's body was also constantly being damaged during this process.

At this cost, he unleashed abilities beyond his physical limits until the moment of collapse arrived, but even so, the black-haired Shirou only managed a draw against the White-haired Killing God.

Although they share the same origin, Shirou has severed his connection with the white god, while the White-haired Killing God opposite him has an inexhaustible supply of energy and will never tire.

If it's a prolonged battle, Shirou is destined to gradually lose ground and be forced into a retreat.

The fight between the two overturned Isaka's house and eventually spilled onto the street, alerting nearby residents who opened their windows to see what was happening.

At this moment, the White-haired Killing God stopped fighting and retreated.

Chapter 1175 Black Shirou and Shirou

As he departed, the White-haired Killing God released a white fluorescent light, which transformed into a thick fog that obscured the view of those who tried to look out. He also repaired the damaged buildings, restored Isaka's house to its original state, and even repaired the iron gate that had been destroyed by the Pheasant Head enemy.

"Shirou! Are you alright?" Nakamura Yuli, finally freed from being pinned by the sword, ran to the black-haired man's side.

"I'm fine, it's just that that bastard wasn't serious at all, which is really annoying!" At this moment, part of Shirou's skin was burned to a reddish-black color due to the battle, with wisps of hot steam rising from it. The skin there looked like a large, rough scar, and it felt like tree bark with a high temperature to the touch.

"Even if he gets serious, he's no match for you Shirou! At worst, we can go back and call everyone to come at us together!" Yuli said, sharing the same righteous indignation.

"Ah! Of course! I can take him down by myself!"

Black- Shirou was naturally not intimidated by the white-haired god.

He was no longer connected to the white god, and his body had returned to human form, albeit with some unique characteristics. He had adapted to the rules of this world, where humans, to varying degrees, possessed superpowers. People called these abilities 'Quirks'.

His unique ability is 'time'; by placing himself in the next point in time, he can regain a healthy body and his injuries will heal. Of course, this ability comes at a price, and it is very costly, so he will only use it as a last resort.

"Um... am I safe now?" Isaka asked blankly, having been left behind. If it weren't for the sticky blood on his hands, he probably would have thought it was all a dream, just like the other people in the neighborhood.

Even someone as powerful as the White-haired Killing God was an extraordinary monster; he simply had no chance to resist.

Shirou said:

"It's alright now. Since he's retreated, it's probably for the best. Compared to making a big fuss and alarming other ordinary residents, your life isn't worth it. That guy values things like order; he won't involve ordinary people."

"Uncle! That's great!" Yuli said, patting Isaka on the shoulder.

'Such talk doesn't make anyone happy at all.'

In short, Isaka is safe now.

"Wait? I'm really safe? No one's coming to kill me again?" Isaka asked, still somewhat incredulous.

"Isaka, you've probably heard of time paradoxes, right?" Shirou said.

"Yes, of course I've heard of that," Isaka replied. "It's about what would happen if you traveled back in time and killed your mother before you gave birth, right? If your mother died, you wouldn't have been born. Hmm, so what would happen to you here? It's that kind of contradiction, isn't it?"

"So, do you know what to do to avoid such conflicts?"

In the movies Isaka had watched before, the premise was that even if someone traveled back in time, they couldn't do anything that would create a contradiction. For example, they couldn't kill their own mother.

"Well, let's use a theory that's closer to this era to explain it. For example, if Isaka and the world you're in now is the main world A, then suppose you want to time travel back to the past and change something."

"Hmm... let's assume you want to prevent your lover from having an accident."

"Uh..." Isaka lowered his head and smiled bitterly, "But I don't have a lover."

Even if you become famous as a writer, a single person can still look glamorous through dressing up, but that doesn't change the fact that they are single.

"I know that! You don't need to say it!" Yuli said.

"It's hypothetical," Shirou continued. "Imagine that in this world, you once had an ideal, perfect lover, but they died in a traffic accident ten years ago."

"I see. So I have to go back in time and save her, right?" Isaka understood the background of the story and used his only talent to make up a story.

"Yes, in that case, you will cause conflict in the world," Shirou nodded and said.

"What will happen when the world is filled with contradictions?"

"Yes, you went back in time and saved your lover, so a woman who originally died in a car accident survived. This world diverged from the original world, thus forming a branch. You can think of it as a new branch growing from a tree trunk."

"And in this world, at that point in time, there will be two versions of you. One is you who traveled back in time from world A to save your lover, and the other is you who was already living in this world and is ten years younger than you."

"Huh? What do you mean? Does that mean that person shouldn't be the past me?" Isaka asked, squinting his eyes, looking conflicted.

"No, imagine if you traveled through time again after that and returned to the 'present,' do you think your lover would have been rescued in the world you returned to?"

"Don't you have one?" Isaka asked in astonishment, his eyes wide, as if he had lost a girlfriend.

"Yes, because your original world wouldn't change. Your actions merely created a division within that world. After all, you started from World A. If you want to go back, you'll return to World A. In that time period, your lover would have already died."

Isaka couldn't help but tilt his head. "I went back in time and did some things that led to the birth of a new world."

"It's not quite the same as this. To be precise, it's the divergence point A, the branch at that point in time. You can think of it as the relationship between a branch and a trunk."

"Thinking of time as a linear progression from the past to the future would be very confusing. It's not like that. You should think of it this way: the past, present, and future exist simultaneously. For example, there are all sorts of forks and intersections on a national highway. You can turn the steering wheel and choose where you like to enter another road. But that doesn't mean that you created a fork in the road by turning the steering wheel and pressing the clutch. The forks were originally set up."

"Where? Where are the branching points located?" Although Isaka knew he couldn't see them, Isaka couldn't help but look around, wondering if there were flags marking the branching points here and there.

"So, if I had been killed just now, wouldn't the world have fallen apart?" Isaka raised his hand, asking doubtfully. If that White-haired Killing God was there to protect the world's order, then what kind of being was his future self?

"When an electron is in a wave-like state, it is there at the same time as it is here; that's its state. But at the very moment Isaka observe it, it stops in one place and becomes a particle. You know about this, right?"

Isaka felt a sense of humiliation, as if he were being questioned about his lack of common sense. "I might have known before," Isaka said vaguely, "But now I'm not sure if I knew or not."

"In the microscopic world, this is true. But in our world, an electron exists only in one fixed place. At the same time, it also exists in another fixed place in another world. Before we observed it, the electron did not only exist in Isaka's world, but also in another world. That's the theoretical explanation. However, well, in short, you can think of it as a parallel universe."

Chapter 1176 The World Five Years Later

"Parallel worlds! I know that!" At least Isaka has some understanding of this.

Isaka breathed a sigh of relief. Even if they talked about parallel worlds, all he knew was what he'd seen in movies and comics.

"There are all sorts of nodes in time, from which several worlds branch out, like branches spreading out. But there are also particularly resilient nodes that cannot be split no matter what, like the trunk of a tree; those nodes are fixed. Do you understand now?"

"The most important thing is..." Shirou asked.

"What's the most important thing?" Isaka asked, his eyes wide.

"The you here now is at most the you in World A. If you want to change the future of this world by killing you, you can only do so at a specific time, not when the branch is dry."

"But that time has passed now. Even if someone comes and kills you again, it will only create a point of divergence. The world will not change at all; it will all be in vain. You are safe."

"I see!"

Isaka was assured that he was safe and breathed a sigh of relief. But looking back, he realized that he actually knew nothing at all.

"Wait? Why would someone kill me? Who are you? That white-haired youth is a hero, right? What is your relationship with him? And what time period are you in?" Isaka had a lot of questions he wanted to ask.

"You'll see then; we'll meet again soon," Shirou said with a mysterious smile.

"Wait? Where are you going? How can I contact you?" Isaka asked urgently.

Shirou waved to Yuli and Isaka, then held hands and walked into an open, rotating wormhole.

Like clothes being rolled into a washing machine, the two turned into long noodles and were sucked into a black hole.

"Wait! I'm going to be a big shot in the future! So, have you found a girlfriend yet?" Isaka shouted loudly.

Unfortunately, the road was completely silent at that moment, and no one could answer him.

Isaka returned home, took a shower, and lay down on his bed. However, he couldn't close his eyes and could only stare at the ceiling counting sheep. The shock to his brain was so great that he developed a fever from the "brain heat." He drifted off to sleep in a daze.

The cells in his body are changing rapidly; something within him seems to be awakening...

Five years later...

No, to be precise, for Shirou and Yuli, it was only a moment.

They got caught in the washing machine, spun around a few times, and then ended up here.

The same location, in front of the Isaka family's house.

The moment Shirou emerged, he pulled a new sailor uniform from his bag and put it on Yuli. The girl was soaking wet, with blood dripping from her clothes.

The tearing effect of a wormhole on any entity that enters it is in no way inferior to that of a high-speed blender.

By this time, Isaka had transformed from a somewhat famous novelist into a bestselling author of superpower-related works. Over the past five years, he had devoted himself to researching superpowers, incorporating the knowledge he had accumulated as a superhero enthusiast, and laying a solid foundation. He had now reached a level where he could engage in equal dialogue with experts and scholars.

Isaka, who had changed his clothes, didn't look much different, except that his hairline seemed to have receded a few centimeters. When he saw Shirou and Yuli again, he was surprised and told them to come in quickly.

"Ah! It's you guys! Where did you all go back then? I'm so confused, and I still haven't been able to find out. Even though I've asked around everywhere, I haven't heard from you, and I can't find anyone to talk to."

"Looks like the time-space connection has been established." Yuli, who was dressed in a new uniform but still looked like she had been immersed in a vat of dye, said.

The white god's clone and Shirou are beings very similar to this world, so they are unlikely to cause conflict within it. However, other stimuli could also affect the world. If Isaka here doesn't know them, then they'll have to go to another world to find them.

"Whoa!!! Yuli -chan, what happened to you? Hurry up and go take a shower," Isaka said.

"It doesn't matter, just give me a towel or some old clothes to wipe myself down, I'll get used to it after a while," Yuli said nonchalantly.

'What kind of apocalyptic hell did you experience? How did the future become so terrible?' Isaka thought devastated.

"Alright, Yuli, you can go now," Shirou said.

"I understand," the girl replied after Shirou spoke.

If there is no better way to travel through the cracks of time, the only option is through the natural passages provided by nature—wormholes. However, the passages inside are not peaceful and must withstand the impact of being cut and torn apart.

Black- Shirou has severed ties with the white god and no longer has the ability to open the white gate, so he can only crawl through it.

Yuli's personality is infinite regeneration. Even if she is stuffed into a meat grinder, she can be resurrected after a nap. She crawls through a wormhole, becomes a pile of rotten flesh, and then recombine.

Shirou stopped the spatial movement in the part of his body that was in contact with him, thus avoiding being torn apart and completing the spacetime travel.

"How did this happen?" After taking the girl into the bathroom, Isaka returned to his own home.

"Passing through a wormhole is a necessary step, so without the superpower of rebirth, almost no one can survive. Even superalloys with specialized hardness will be cut into pieces."

"Time and space? Is it really that difficult?"

He could understand the theory of parallel worlds through comic books and novels, such as time travel. His first impression of time travel was a Blue Fatty that crawled into a drawer.

"Yes, I won't go into the details. For example, when talking about the topic 'it will rain tomorrow,' there's no need to go on and on about 'why it will rain,' isn't it necessary to just say directly, 'Because it will rain, don't forget to bring an umbrella'?"

Shirou said.

"Instead of explaining, it should be faster for you to experience it with your own abilities," Shirou, extending his hand to Isaka.

How do you know...?

Isaka was about to ask how Shirou and the other person knew about his awakened ability when he remembered that Shirou and the other person came from a much more distant future and must know his details. He almost asked a stupid question.

Isaka hesitated for a moment, but still took Shirou's hand. His ability wasn't just through handshakes; he could also communicate telepathically with people and see what they were thinking while shaking hands.

Of course, humans cannot function properly without distractions, so both parties must undergo a period of focused training in order to see detailed and accurate information.

Fortunately, Shirou doesn't seem to need any special training.

At that moment, Isaka saw a dilapidated house...

Chapter 1177 The Future of the World is Despair

Several tables and chairs were placed against the wall, the center of the room was empty, and then... a mountain was piled up in that empty space.

After a while, Isaka realized that the small hill was a pile of people, and he was stunned. Although he didn't know if they were dead or dolls, it looked like a massacre after burning or a platform like a concentration camp in World War II, which felt very unreal.

Is this Nanjing during World War II? Or Nazi Germany? Only a few locations came to mind for Isaka, because even the East Japan Earthquake couldn't compare to the devastation here.

"This is Japan," Shirou's voice came through.
