No one knows parallel worlds better than Bai Lan.

Mare's Sky Ring is still on Bai Lan's finger, and his ability to spy on parallel worlds has always existed.

But he said he didn't know about the world ten years ago.

"I can indeed see the development of parallel worlds." Bai Lan propped up his chin, and his purple eyes cast a shadow under the light, which seemed a bit gloomy. He said in a brisk and sweet tone: "But I can only see what the 'I' in the parallel world sees."

Bai Lan never likes to speak directly, he prefers to be roundabout and let the listener come up with the answer himself. And the few people present are all people who know Bai Lan very well. Irie Shoichi is his good friend - although Irie Shoichi himself has always been a little...subtle about this title because of his memory ten years later, about his betrayal and becoming an undercover agent.

Not to mention Uni and Sawada Tsunayoshi.

Sawada Tsunayoshi couldn't help but frowned, and easily understood what Bai Lan meant: "That is to say, not only does that world not have me, but also no 'Bai Lan'?"

In this way, things become particularly complicated.

"It's not certain yet, Tsunayoshi-kun." Bai Lan lay on the table as if he had no bones, "Isn't that little Tsunayoshi-kun from that world? It's just that he doesn't exist in the eyes of ordinary people."

"What's more--"

As a former enemy of Sawada Tsunayoshi, or even if he is not evaluated in this identity, just with Bai Lan's eyesight, he can be sure that Shi Wu is not as simple as he looks.

——No, it's the unique individual Sawada Tsunayoshi. Although he looks as weak as a rabbit, at the critical moment, this person can always burst out with unimaginable strength.

Since the matter concerns the world, Sawada Tsunayoshi did not hide the conversation he had with the mother of the world ten years ago.

Just thinking about this conversation, and then thinking deeply about the glass jar that Sawada Tsunayoshi entered for the first time when he went to that world because of the bazooka ten years later, anyone would imagine that the newly born Vongola descendant was captured and imprisoned by someone, causing Nana's mother to mistakenly think that her child was not born or something -

the meaning of those words of the Sawada Nana in the world ten years ago did not sound like she had not expected the birth of her child.

Originally, he might be an enemy of the Vongola, but because the world was about to collapse, he became particularly vulnerable.

Whether it was the scars on the body of the "Sawada Tsunayoshi" from ten years ago, his body's instinctive reaction to fighting, his defense against Byakuran - and the fact that he knew the Vongola guardians and mother, according to the most reasonable guess.

The only thing left was that the Sawada Tsunayoshi from ten years ago had his own partners and also went to the future to try to defeat Byakuran. Maybe he succeeded, maybe he failed, but in this situation it is not important. The most important key is that because of some circumstances, someone said that the world was going to be destroyed, and his existence is the opportunity to save the world.

So, Sawada Tsunayoshi ten years ago chose to use his own flame in exchange for the possibility of the world not collapsing.

Especially after Shiran joined Shoichi Irie's observation, a new conclusion was reached.

"That world should have been destroyed, right? It was just that something temporarily provided, or activated the energy of the cornerstone of the world, so the time of collapse was delayed to a year later."

Shiran himself is a very good researcher, and the technology he possesses is far beyond this world itself. And Shoichi Irie also proved the truth of Shiran's words.

- This is indeed true. Because this is what the system does.

So, thinking back to the flame on Sawada Tsunayoshi's body that has not yet recovered, their guess is more likely to be correct.

At this time, Yuni spoke up, saying, "This matter is indeed very urgent, but... if Mr. Tsuneyoshi doesn't want to say it, we shouldn't force him to tell the whole truth."

The Mr. Tsuneyoshi that Yuni was referring to was naturally Shi Wu.

During the conversation with Yuni, Shi Wu thought he had said everything he could, but he concealed the system's affairs, so how could he have hidden it from the two very sensitive Daisora?

Masaichi Irie was a little puzzled. As a science student, his mindset made him focus only on the collapse of the world. "If Tsuneyoshi-kun had told me the truth, it would have been much easier for me to handle this."

However, Shiran was not surprised by Uni's attitude, and he was also very casual. "I don't care. That world has nothing to do with me~"

Masaichi Irie suddenly shouted, "Master Shiran——!"

"Xiaozheng is still the same~" Shiran smiled and narrowed his eyes at Masaichi Irie's reaction.

Tsunayoshi Sawada glanced at Yuni: "Did you see anything, Yuni?"

Yuni kept a sad and tolerant smile on her face and shook her head gently: "I won't tell anyone if he doesn't want to say it."

Yuni put her hands together and said softly: "Next, I'll leave it to Mr. Shiran and Mr. Masakazu."

The girl's eyes were full of trust, and she completely believed in the abilities of Shiran and Masakazu Irie.

Tsunayoshi Sawada withdrew his gaze thoughtfully.

The research matters were handed over to the dedicated objects, and now the only problem was Shi Wu.

Yuni suggested not to be too anxious, just let it go, and treat Mr. Tsunayoshi with the most ordinary attitude.

And this is what Tsunayoshi Sawada has been doing during this period.

Although there is still a year's countdown before the collapse of the other world, it does not mean that they can really delay it to a year. The longer the time takes, the greater the variables. Moreover, no one knows how long two identical beings can persist in the same world.

But these things are all unknown to Shi Wu.

Shi Wu healed his injuries during this time, at least he does not need to continue sitting in a wheelchair. It's just that this base is not his home after all, and he will not walk around casually in most cases.

But apart from this point, the reason why he does not move around casually is...

"To be honest, I didn't realize before... I am more uncomfortable with this body than the one with Ranbu." Shi Wu complained to the system in his heart.

"Ranbu's vest is very healthy, the most is that the body's reaction is not that fast. I didn't need to make any big or fast reactions at the time, so there was no problem."

"But this time... the body's reaction speed is fast enough, and I can also tell that this body has enough training and combat experience--"

At this point, Shiwu began to turn around. He said sadly in a dry tone similar to the system: "It is such an excellent vest, but it seems to have been seriously injured and lost too much blood, and has some kind of disability."

It is a feeling of weakness that can spread from all parts of the body. It is obviously very healthy. It is natural to feel weak when it was injured before, but the injury has healed and this feeling of weakness still remains in the body-

Shiwu now has a deeper understanding of the "disability" of not having flames.

[...You can redeem it.]

Shiwu:?

[The essence of flame is also a conversion of energy, you can redeem it. Just like redeeming a pair of artificial eyes for "Edogawa Ranpo" at that time, it is a kind of "completion" relying on external forces. 】

【It's just that the exchange has its flaws, just like the artificial eyes are just artificial eyes, you can't let "Edogawa Ranpo" see the world clearly, and the exchanged flame is just a disposable prop. 】

"...Oh." Shiwu blinked, tilted his head and said uncertainly: "Thank you?"

His complaints about his body were just complaints, but the system seriously helped him to recover, which made Shiwu's mouth curl up slightly.

At this time, the door was knocked, and Shiwu stopped communicating with the system.

He once again restored the timid and gentle manner that Tsunayoshi Sawada should use, and said obediently: "...Come in!"

The person who came was...

Shiwu distinguished it a little, and then he saw the traces of the other party's childhood in this unfamiliar face.

It's Sasagawa Ryohei! The Guardian of the Sun of the Vongola.

Ryohei Sasagawa is a very enthusiastic and cheerful person. Without waiting for Tokiwu to say anything, he walked in with a smile on his face and hooked his arm around Tokiwu's shoulders.

"I was a little confused when Sawada told me just now! Anyway, I don't understand those things. Anyway, you are Sawada, right?"

"It's a waste of youth to stay in the room all the time!" He didn't know if it was Tokiwu's illusion, but he always felt that he saw a burning flame in Ryohei Sasagawa's eyes: "Move to the extreme! Sawada!"

"But the most important thing is! Have you eaten?"

Without Tokiwu being able to react at all, he was passively pulled out of the base by Ryohei Sasagawa, holding his shoulders.

It was not until they were on the street that Shi Wu realized it belatedly and cautiously asked the silver-haired man next to him who was much taller than him: "... Is it really okay for me to come out like this?"

Sasakawa Ryohei looked even more confused than him: "Ah? Is there a problem?"

Shi Wu: "..."

Shi Wu resisted the urge to rub his forehead, but he could not control his thoughts of complaining. He said helplessly: "Brother, you are really the same as always, you haven't changed at all."

Calling the other person "brother" was a detail that Shi Wu noticed in the file.

Sasakawa Ryohei laughed and patted Shi Wu on the back. The action seemed quite rough, but there was no pain in the world. Shi Wu could not tell whether the system blocked the pain or Sasakawa Ryohei himself eased up.

"Aren't you the same, Sawada?" Ryohei Sasakawa said cheerfully, "Nothing has changed in the past ten years."

Tokiwa didn't care where he went - he wasn't familiar with Namimori anyway, and couldn't tell which one was good or bad.

But after seeing the name of the store and the boss's face that looked a bit like Yamamoto Takeshi, Tokiwa knew that this was Yamamoto's Bamboo Sushi.

Yamamoto Takeshi's father, Yamamoto Tsuyoshi, didn't seem to show any other emotions about the fact that "Sawada Tsunayoshi had become smaller". He casually talked to Ryohei Sasakawa in a familiar manner, and then served the sushi.

Shi Wu passively accepted Sasakawa Ryohei's arrangement until Sasakawa Ryohei only ate two servings of sushi and stopped eating. Shi Wu subconsciously asked, "Aren't you going to eat more?"

"Hmm?" Sasakawa Ryohei replied with a nasal tone, but he didn't care much. He smiled and replied, "I'm full!"

He thought he had found a reason. Looking at Shi Wu who was much slower than him, he said cheerfully, "Don't worry about me! If you're not full, just order another one!"

"...No, I'm full too." Shi Wu put down his chopsticks and looked at the three empty plates on the table. He always felt that something was wrong.

Sasakawa Ryohei didn't order the kind of sushi that was separated, but something like a set meal. The portion was actually quite large. The appetite is much larger than that of a normal person.

However, Shi Wu still thinks that there should be more than ten or twenty empty plates.

Can he really be full with just this little? Shi Wu looked at Sasakawa Ryohei in confusion, and shifted his gaze when the other party noticed him.

...Maybe he really thought too much? How can a normal person eat so much. Shi Wu pursed his lips and put this small problem behind his mind.
