(Thank you for the reward of the flowers on the ink, I didn't get up yesterday, and I only got up at noon today, sorry)

TPPD, or "Time-Plane-Destroyed-Device", is a kind of semi-mechanical space-time machine similar to that used by people in the future, such as Minoru Asahina, and is referred to as a 'space-time machine'.

In the eyes of the future, time is caused by the infinite stacking of countless time one-sidedness in a flash, and each one-sided time is not continuous between each side, just like a cartoon was originally made up of more than 24 original pictures scrolling in one second. Although due to the impetus of the space-time axis, the possibility of a large time fault between the time sides tends to zero indefinitely, the magical little machine "TPPD" cleverly makes use of this characteristic of time, as if adding an extra frame to the 24 frames, cleverly realizes the space-time shuttle, and has a predetermined impact on the existing space-time axis.

Just like on the seventh day of July, Ah Xu and Little 1096 successfully returned to three years ago, attaching the important information of 'going to North High School' and 'John Smith' to Captain Lori.

Time is complex, rigorous, as delicate and ingenious as a chain of plural numbers – but also incomparably fragile.

For example, during the Qixi incident, Ah Xu, who was lying on a park bench, only had to stand up and turn fifteen steps to the left, and he could see another stupid face staring at a surprised winter coat......

Therefore, in order to maintain the normal operation of time and space, and to make better use of the time machine, people in the future have spent a huge amount of manpower to build a monitoring system for time and space to prevent and respond to possible time disasters.

About five days ago, for the first time, this huge space-time surveillance system sounded a warning report of disaster......

"Time is collapsing, starting from the point of November 24 of this year, and continuing until the early morning of December 18, the entire timeline is like the signal of Asahi Station suddenly becoming Tokyo Station, from the established time to a completely unknown time for the Time and Space Bureau. Immediately after that, centered on the collapse point, the timeline begins to collapse at the normal flow rate of time, losing a large part of the antecedent causality contained in the given time, and the entire future is at risk of annihilation. "Da Asahina's face is very unsightly, although she has grown into an intellectual and mature big sister, but her nature is still like a weak puppy who needs to be taken into her arms and taken pity, and her pitiful appearance at this moment almost melted the hearts of the three Ah Xuan present.

"Ah, Asahina-san, although your words sound as confusing as little Asahina-san, who is full of 'forbidden matters', just look at your face as if the world has been saved......"

The otherworldly void and the original void showed exactly the same idiot expression, staring at the big Asahina stupidly. Their exact reaction made Liang Gong next to him hug his chest and let out a disdainful cold snort.

"What two stupid faces." The adult version - according to the development of time, we call it the future void - the future void looked at the self of the isotope in different time with disdain, "In short, what Asahina-senpai means is that for some unknown reason, the timeline has gone to another fork in the road, and as a result, the future that has been formed has gradually disappeared." ”

"This disappearance means everything that contains the future." Hao Shen pinched his chin, he didn't have any pressure to understand what Future Void and Da Asahi said to Bina, "This is also normal - if time here starts to move in the other direction, then the original future belongs to a timeline that has not happened at all, and what has not happened will certainly not continue to exist." ”

"That's the truth. But the reality is even more serious - the timeline is not only collapsing backwards, but also collapsing forward, and finally stopped three years ago......" Future glanced at Hao Shen in vain, in fact, he had been paying attention to Hao Shen for a long time since returning to this point in time, "We don't know what's going on, but it's obviously not good to let time continue to collapse like this, in this case, the Future Time Bureau has sent the most suitable commissioner to investigate the cause of time, and it's best to save it if you can...... As you can see, it's Asaka-sani and me. ”

"So, will I become a colleague of Asakana-senpai in the future?" The original version said a little excitedly.

"Unfortunately, it's not." Future Void rolled his eyes, looking very unhappy with this question, "You don't want to ask me about the future!" The reason why I'm here is because the timeline here is when Nagato has a bug, and I'm the only one who is most familiar with this time except for Asahina, and ...... There's no one better suited than me. ”

As he spoke, he looked at the long-haired Lianggong on the side, his eyes full of helplessness.

Able to change the world and reset the entire timeline, who else can this fearless ability be besides Nagato and Suzumiya? The two of them can change the world, and Ah Xuan can change the two of them, which is the real reason for the appearance of the void in the future.

"But then again, what's going on here? There are no two mes in my memory, and besides, who are you? Future Xuan said, his eyes pointed directly at Hao Shen, and at the same time, Da Asahina, who was originally depressed, also raised his head and looked at Hao Shen curiously.

"I, I'm ......" Hao Shen spread his hands, and when he was about to say something, the girl in Lianggong couldn't help jumping up, and said in a rather proud tone: "He is Hao Shen, a god from another world!" ”

"Huh?" The two of them were dumbfounded, and Future Xuan looked at Hao Shen and Liang Gong vigilantly, "People from another world? Summoned by Spring? ”

"Unfortunately, it's not." Hao Shen pressed Liang Gong's head, pulled the excited girl aside, and then said: "Actually, I came on my own initiative, firstly to send Ah Xuan home, and on the other hand, to save the world, this matter is complicated to say......"

It's obviously a bit of a waste of time to say the whole incident again, but the explanation at this moment is also necessary, looking at the eyes of the two, maybe they are all suspecting that Hao Shen is behind all this. Therefore, Hao Shen could only briefly explain his origin and what the whole world was about to face.

Future Xuan and Asahi Bina were a little blindsided at that time, and after a while, Asahi Bina let out a "woo", and the whole person fell to the ground softly, as if he was about to cry. Future Void Robbed in front of the Otherworldly Void and the original Void to support the soft Royal Sister Beauty, in the angry eyes of the two, said bitterly: "In other words, the culprit of this incident is actually an invader from another world?" No wonder ......"

Hao Shen was stunned for a moment, and hurriedly asked, "What, do you know something?" ”

"Uh......" Future Void glanced at the people who had been attracted by this, with a look of hesitation. He did have some information, there has been a large fault between the current future world and the past world, and the Time and Space Bureau has spent quite a huge amount of resources to send them to the past, so of course they have done their best, and after crossing dozens of points in time, they finally discovered some information, which is quite important, and it is not something that can be said by just one person.

However, after hesitating for a while, Future Xuan still gritted his teeth - he didn't believe Hao Shen, but he believed in himself, his past self.

"It's Nagato." He gathered his thoughts for a moment and said, "At the same time as the future world, Nagato lost contact. I've been to many points in time with Asahina-senpai.,But all of Nagato can't get in touch with Nagato after November 24.,At first, we suspected that for some reason Nagato's bug appeared in advance.,But after contacting Nagato in other timelines.,,It's not like that.,And,Disappeared with Nagato.,And all the information after November 24 and all the existence related to it! And we're here because...... This is the last time fragment of any 'collapsed' timeline that can be reached, if Nagato can't find fault with it......"

Speaking of this, the future sighed in vain.

Hao Shen nodded, digesting the information.

I see, is the key person who is causing the world's problems today Yuki Nagato?
