"Shoichi." Tsunayoshi Sawada greeted the red-haired young man who was holding his stomach in front of him, "It's hard to explain over the phone, so I came directly here."

"...Tsunayoshi, can you tell me what just happened?" Shoichi Irie sighed. He looked at the people who had been standing beside or behind Sawada Tsunayoshi, and listened to their explanations with a helpless expression.

Because of the battle ten years ago, Shoichi Irie, at the age of ten, had tacitly become a member of the Vongola Technical Department when he was in his teens and had not yet shown his scientific research ability.

At that time, when he got the memory of his future self, Shoichi Irie felt that his stomach ached so much. He really didn't think that his future would experience such complicated and troublesome things.

Being an undercover agent is not suitable for him at all... Besides, he is just an ordinary person! Why would he be involved in the mafia, the destruction of the world, and so on!

Unfortunately, what has happened cannot be ignored. The future Shoichi Irie can research those things. At the moment when he got the memory of his future self, it was really difficult for Shoichi Irie to control his hands to continue to study.

It can be said that the memories he got allowed Shoichi Irie to skip all the roads he needed to explore in the middle and directly find the direction that suits him best.

Therefore, Shoichi Irie, who contacted the Vongola ten years earlier, has abundant research resources.

And because of the war ten years ago, Shoichi Irie consciously monitored and protected the stability of the world-he was really afraid that another inexplicable future self would suddenly come and ask him in the past to do something!

He is just an ordinary researcher!!

And he has been under surveillance for ten years. Although something may happen occasionally, most of the time, the cube of seven is stable, and the Marley Ring is in Byakuran's hands. Although it was initially under surveillance because Byakuran had destroyed the world.

But something happened later. Because Uni guaranteed Byakuran, the sealed Marley Ring was returned to Byakuran. What's more, Uni's family was the one that guarded the Marley Ring.

"Tsunekichi, do you remember the battle ten years ago? The battle about Western-faced checkers and the lifting of the curse of the Rainbow Child." Irie Masakazu brought Sawada Tsunekichi and others to his laboratory.

The room was a bit messy, and the random placement of things made Irie Masakazu blush in embarrassment.

Hearing this key word, Sawada Tsunayoshi almost subconsciously glanced at his tutor - Reebok, who was now slowly growing up.

He was no longer the guy who simply thought that Reebok was a baby ten years ago. To be honest, now recalling it, he was a little puzzled as to why he could not recognize the baby Reebok and the grown-up Reebok when the curse was temporarily lifted. He

also completely regarded the grown-up Reebok as a stranger.

After all, even if he could not recognize him, his super intuition should tell him the answer.

In fact, he had been in charge of Vongola for almost five years, which was the time when he should have been in college. He watched Reborn grow up and sighed that Reborn looked alike to the gentleman he met at that time. When Reborn looked at him with contempt, he suddenly realized the answer. Before

that, he had never considered them as one person... There was such an obvious example as Lal, why couldn't he react all the time...!

Having guessed what was in his student's mind, Reborn had a half-smile on his face. This expression made Sawada Tsunayoshi instinctively shrink his shoulders and look away, saying to Irie Masakazu: "Of course."

Irie Masakazu exclaimed: "That's easy to explain."

"At that time, although the machine made by Mr. Taluobo made our world no longer need the Rainbow Child's Jinchūriki."

"But in order to ensure that the prop was successfully activated, we needed a large amount of flame at that time. Tsunayoshi-kun, you all, injected all the flame in your body into that prop."

The specific things were not so easy to explain at once, but fortunately, everyone present had experienced that battle, so they could understand it without explaining it too clearly.

"And this only liberates one of the seventy-three powers. It's not just the pacifier that is needed to maintain the stability of the world, there are also the Vongola Ring and the Marley Ring."

"The Vongola Ring is not like the pacifier back then. It is tied to the Rainbow Babies. As long as they exist in this world, no matter where they appear, the stability of the world will not be destroyed."

"But just now, the machine I use for monitoring suddenly fluctuated. The chaos in the numbers was similar to the fluctuation caused by you choosing to destroy the Vongola Ring back then."

"So, it wasn't me who chose to destroy the Vongola Ring." Tsunayoshi Sawada complained.

"Now is not the time to complain about this!" Irie Shoichi held his stomach, and he really had no way to deal with Sawada Tsunayoshi's occasional jumpiness. He continued: "In other words - just now, the Vongola ring suddenly disappeared in this world."

"The world has a certain self-correction ability. If it was only a short five minutes, even if the Tsunayoshi you exchanged with ten years ago did not wear the ring, the world would not have a very obvious reaction."

Irie Shoichi said a bunch of complicated terms again. Noticing that there was no difference on the faces of several people, and they were actually completely confused, Irie Shoichi paused, thought for a while, and used the simplest metaphor to describe it: "Simply put, the world that I exchanged with Tsunayoshi ten years ago was quite unstable, and it even affected our world."

"And the world thinks that you disappeared with the Vongola ring and will never come back."

Sawada Tsunayoshi's expression became a little more serious, and then he said: "This is why I came to you, Shoichi."

Before the red-haired young man showed a stomachache expression, Sawada Tsunayoshi said: "I need you to help me find the coordinates of my world ten years ago that you just exchanged with me. I want to go there again."

Without Shoichi Irie's reaction, Jikudera Hayato immediately became excited: "This is too dangerous! Tenth generation!"

Yamamoto Takeya agreed with Jikudera Hayato's words: "Although I didn't hear it very clearly, that world is very dangerous, right? Tsuna, have you really thought it through?" Reborn,

on the other hand, did not have any surprised expression, as if he knew from the beginning that his student would make this choice.

Irie Shoichi was also a little hesitant: "Tsunayoshi, are you sure? Although I can determine the coordinates... After all, I did the same thing ten years later, so I am familiar with it..."

The red-haired researcher complained in a low voice, and then said: "But at that time, it was because of Lady Shiran that I had to make that choice. In fact, there were many unstable factors in the middle. In fact, luck also played a role in my success at that time."

Irie Shoichi has never changed his way of addressing Shiran. Amid

everyone's disapproving gazes, Sawada Tsunayoshi smiled and said, "Well, I'm sure."

"I'm a little concerned about that world." Sawada Tsunayoshi has not met Shiwu, and without seeing it with his own eyes, it is difficult for him to imagine what his partner has experienced through his partner's words.

But he has actually been to the space where the system temporarily blocked him, although his super intuition had been issuing alarms at the time, "But, I always have a feeling."

"Someone... is asking me for help."

Sawada Tsunayoshi, who has always had a very strong empathy ability, frowned, and his warm brown eyes were filled with an irresistible tenderness and the firmness of having made a decision.

This is also the reason why Sawada Tsunayoshi reached out his hand without hesitation. He wanted to know what happened to himself in that world, and he wanted to save people - no matter who the other person is, whether it is himself ten years ago in the parallel world, or even a stranger, Tsunayoshi Sawada will lend a helping hand.

It is precisely because Tsunayoshi Sawada is such a person that the guardians have been following him.

Even though he has become a dirty mafia member in the mouth of Rokudo Mukuro, Tsunayoshi Sawada has never changed. He is still the most gentle boy.

Time has only brought him a more mature way of doing things and a stronger heart.

For such a Tsunayoshi Sawada, Hayato Gokudera and Takeshi Yamamoto can no longer say no - or rather, they already knew the choice of their leader, but they cared about the other party's safety more than anything else, which made them react like that.

So, Jikudera Hayato's eyes fell on Shoichi Irie with a fierce and threatening look: "Listen carefully! If anything happens to the tenth generation--"

"Hayato, don't bully Shoichi." Sawada Tsunayoshi turned his head and said helplessly. Jikudera

Hayato's face immediately changed: "Yes! Tenth generation!" Jikudera

Hayato couldn't threaten him, and Yamamoto Takeshi spoke: "Hahaha, Shoichi, your equipment here is very interesting, I'm very interested, can I stay here and play for a while?"

"--These things are not for playing!" Shoichi Irie said with stomachache .

Stomachache has almost become an everyday adjective for Shoichi Irie.

Ribaoen pressed down the brim of his hat, the corners of his mouth slightly raised, and did not comment on it.

"So, what is the mission this time?" Shi Wu asked the system.

"Or is it that this world has ended, and we have to change the world?"

Since the previous worlds were all like this, Shi Wu was not surprised by this result.

However, the system denied this answer.

Under Shi Wu's puzzled gaze, the system was silent for a long time, and seemed to have finally confirmed the situation before answering, [You can still rest for a while. ]

[Your mental state is not as good as you think. If you continue to complete the task under this situation, you will only get half the result with twice the effort. ]

It was difficult for Shi Wu to deny this, and he had to admit it. Otherwise, he would not be easily influenced by the vest and regard a stranger as his mother...

Shi Wu's eyes lost their original bright luster and looked a little dim.

[……]

[… Nana Sawada has a very strong personality charm, and she is a very good mother. 】

Suddenly hearing this, Shi Wu was a little confused: "Eh?"

The author has something to say: Shi Wu: Are you comforting me?
