Roman, a man who can give everything he has in order to save people, when saving people is doomed to fail, when the efforts of his companions are doomed to be useless, when the defeat comes, when he is the only one left in the whole world, what kind of despair and loneliness he has in his heart, through this diary, everyone can clearly feel it.

If it was someone else, he might have given up and couldn't bear that kind of pain a long time ago, but Roman didn't, in the alone Chaldeeas, he still didn't give up hope, took the responsibility of saving people on his shoulders, struggled alone, and then, before he died, finally carved this path of hope.

However, in the end, all he was waiting for was a near-impossible future.

If Tang Hao hadn't come here, no one would have even been able to see this diary, and no one would have known how hard he worked.

Holding this diary, Tang Hao felt an unprecedented heaviness.

No one even spoke in the chat room.

Until......

[The world has retrieved information, and the number of people who can join the chat room in the world is 3]

[Current World Inviteable Group Members: None]

[Exclusive Quest Activation: Accept the commission of Romani Akiman, travel to the distant past, complete the puzzle to save people, get an exclusive invitation card after the mission is completed, and randomly select one of them to join the two-dimensional chat room between Romani Akiman, Matthew Killette, Rika Fujimaru and Leonardo da Vinci]

Looking at the messages that popped up in the chat room, Tang Hao fell silent.

From a personal point of view, he really wanted to take it, since he was fortunate enough to come here and was fortunate to see Roman's diary, then, just for this fate, he wanted to take this hope for Roman and complete his ideal puzzle.

However, it is one thing to be able to pick it up, and it is another thing to be able to complete it.

Easiestly, how does he go back in time?

Roman just opened a path to the past, but Chaldea is no longer able to function normally, without Chaldean's ability to transfer the spirit son, it is simply empty talk to return to the past as a human being, otherwise, Roman in the diary will not be so desperate, can only wait for someone who is almost impossible to come here.

As for repairing the Chaldeans, it is even more impossible, where did he get this technology!

"Let's take it."

At this moment, Yakumo's purple voice suddenly sounded in his ears.

"Huh?" Tang Hao was stunned for a moment, "What's wrong with you, you actually let me take on this kind of task?" Obviously, when you were in the world of Wild Rakami, you still strongly opposed it. ”

When he was in the world of Wild Rakami, the difficulty of the task Tang Hao faced was only that it was possible for him to die, and Yakumo Zi at that time persuaded him to give up, and now, if he took this task, he would not be able to leave this world until it was completed, and he had no means to return to the past, once the effect of the net charm disappeared, he would have to die here.

You don't have to worry too much about things like spell cards and chat rooms to support you, but go back in time......

Huh?!

Going back to the past, it was impossible to change the past, but now that there is Makise Red Riqi in the chat room, the mother of the time machine, how is it impossible?

"Haha, it looks like I can only take it."

Tang Hao laughed out loud, since everything is possible, there is no reason to give up.

"Assistant, I'll leave the time machine matter to you."

"Wait, wait!" Seeing that Tang Hao was about to take over the task, Maise Hongliqi hurriedly said in a panic, "I'm glad that there is a place that can help you, if it's to save that world, I can also make a time machine, but...... Even in the anime, it took me years to build a time machine, and even if I could build it now, it would take at least ten years, so long ......."

She couldn't imagine how Tang Hao could survive in that world for ten years.

Kaguya smiled: "You little fool, have you forgotten your concubine?" If you want to build a time machine, you can come to my time hut, you have the technology and theory, and I have all the materials and time you need, and nothing else...... We can also ask Kappa Heavy Industries for help, and even Yakumo Purple can go to the outside world to find all the technical support you need, combining the strength and technology of both you and me, plus the Time Hut, not to mention ten years, it doesn't even take a day. ”

"Ahh Makise was obviously stunned, and then said, "I understand, since that's the case, of course I don't have a reason to sit idly by, okay, I'll come to Gensokyo right away!" ”

"I'll go with you too." Rentaro Okabe said suddenly.

"What's the use of you?"

"Hahaha, assistant, have you forgotten, I'm a mad scientist Phoenix Academy, how can I be without a time machine to break the chaos? Hoohaha......"

"Ahhh

Through the mobile phone, Tang Hao smiled slightly, knowing that there was no problem, so he took the task, and said in his heart: Roman, this hope of yours, let me realize it for you.

Makise Kori and Rentaro Okabe immediately set off for Gensokyo, while Yakumo Murasaki sent her Shikijin Yakumo Blue to ask Kappa for help...... Gensokyo's kappa is not simple, although it is a youkai, but it likes to develop in the field of science and technology the most, and even nuclear bombs can be built, which can provide great help in technology and materials.

In addition, everyone in the chat room is also discussing separately, and the chat room, which was originally a little heavy due to Roman's diary, has now returned to a relaxed and happy atmosphere, and everyone has witnessed how powerful this chat room really is, even if the world has been destroyed, there is hope to restart again.

And after discussing it for a while, Mikoto Misaka also decided to go to Gensokyo to help.

Although she doesn't know much about a time machine, as a near-universal superpower on the scientific side, she can still help a little, right? Anyway, building a time machine in a time hut won't take much time in reality.

Maybe you can bring a few more people along......

Looking at the endless discussions in the chat room, Tang Hao's mood gradually relaxed, sure enough, compared to the dark and cruel, he still prefers this kind of relaxed and beautiful thing after all, when a person encounters difficulties, as long as he @ in the group, someone will come to respond and help with all his might, so ...... Far from despairing, Roman!

While the time machine had not yet been made, Tang Hao continued to wander around the Chaldea of destruction to see if he could find anything else useful, of course, compared to before, his mood was much lighter now.

Huh?

It didn't take long for Tang Hao's heart to suddenly move and think of a question.

"The things mentioned in Roman's diary are a little different from those in the game, if it is because he observed that human reason is doomed, so he changed his actions, which can be explained, but ...... What exactly is the fragment he is talking about? Why is a piece suddenly missing from the good ones? ”

According to the plot in the game, there is no fragmentation at all, which makes Tang Hao unable to understand.

Soon, Yakumo Murasaki mentioned a name.

"Sakura Tosaka."

Cherry?

"This ...... It can't be, right? Although saying this, Tang Hao still felt a tingling in his scalp.

"The butterfly effect."

"But...... If I'm not mistaken, the world of FSN and the world of FGO are actually two different parallel worlds, and even if Sakura leaves, it will have some impact on the world of FSN, so why will it affect the world of FGO or even Renli? ”

Yakumo Zi said: "The butterfly effect, where is it so easy to explain clearly, the world of Gatia is not only for the world of FGO, but for the entire type of moon The human body is burned, since FGO can affect other parallel worlds, then these worlds in turn affect the FGO world, what's the problem?" ”

"And...... Didn't we take Sakura away with us? ”

That's right, the Holy Grail Piece!

Tang Hao suddenly remembered, a cherry blossom and a Holy Grail Piece, this is what they took away in the Fourth Holy Grail War, if according to Yakumo Purple's logic, this is the reason for the fragment, then ...... The people of the FGO world are burned, but in fact, they have to blame him?

So in the end, the task of continuing the puzzle fell on him, and it didn't seem to be wronged.

"Wait, if we caused the destruction of the world, the inhibition should be able to see this future, why didn't it stop us at that time?" Tang Hao asked again, although there are not many cases of inhibition to make a move, but in the face of such a huge thing, he should still make a move...... Right?

"Who says inhibition didn't strike? Otherwise, how do you think the old man of the gem came from? Yakumo asked rhetorically.

Tang Hao was stunned for a moment, "Jewel Weng? Did he show up? ”

"He was blocked by me, of course you can't see it, and his appearance in front of me obviously can't be a coincidence, most of it is the influence of inhibition. And Kaguya went to Valhalla, if it wasn't the interference of the inhibiting force, I don't believe it, but how to say it...... I'm afraid the chat room also provided some shielding for our tasks, so that the interference of the inhibition was very weak and did not have a noticeable effect. ”

"Okay......"

Hearing Yakumo Zi say this, Tang Hao finally understood, it seems that in the Moon World, there is no such thing as coincidence, and I thought it was a coincidence, but now I look back...... Is it all foreshadowing?!

Subsequently, Tang Hao waited for about five hours, and when the second net charm was about to run out, the voice of Makise Hong Liqi finally came from the voice channel.

"Time machine, it worked!"

Five hours in reality is equivalent to five years in the Time Hut, which is far shorter than the time used in the original Stone Gate, which shows how powerful the support provided by others is.

Then, this time machine was teleported to Tang Hao's favorites.
