Jiang You returned to the Health Office. With this, the modified history and the present timeline merged, successfully achieving the outcome he desired.
"You really made me wait a long time, didn't you?" She still wore the same white coat as when they first met, but this time, her gaze was completely different. "Taking the liberty of turning me into the version you wanted... you must take full responsibility. This time, I am fully prepared."
For Jiang You, it had only been a moment. Just a second ago, he had said goodbye to Sesshouin. However, he couldn't refuse her enthusiasm.
Sesshouin directly locked the Health Office door from the inside. Now, any problems the students had were no longer her concern.
After Sesshouin finished pouring out her longing, Jiang You also extended an invitation to connect worlds. The most unstable factors in FE were her and B.B. With this one resolved, the matters in FE were considered settled. As for B.B, Jiang You recalled the events that happened in "Reality." She had clearly seen through his problem, yet she still approached him, obviously looking for some amusement. In that case, he would play along with her for a while longer. He would keep giving her the cold shoulder and see how long she could keep up the act.
As for whether B.B. would cause trouble, Jiang You didn't have to worry at all. B.B.'s authority could be sealed at any time, making her the easiest type to deal with.
All in all, the matters in FE were basically over. Next, there were only the matters on Miyu's side and the Faerie Realm. To be honest, he hadn't figured out how to deal with the Faerie Realm yet, because what Morgan needed wasn't ordinary help, but to let go of her grudge against Camelot. In the original story, she never let go, which was why the Faerie Realm eventually fell into an irreversible collapse, forcing her to accept reality helplessly.
He could only say that since Morgan wanted to continue, she should just keep going. However, Jiang You still wanted to help the humans over there. Before, he had just treated it as background setting with a gaming mindset, but now that he knew this was reality, they were living, breathing humans. Helping his fellow humans escape those trash fairies was a matter of course.
With that settled, after Jiang You had settled Sesshouin, he went directly to the Throne Room where Morgan was located.
Jiang You knew that Morgan's main body must be here. She was here controlling the Twelve Replica Holy Spears, always on guard against the revival of the Great Cernunnos (corpse).
"Without an announcement, even you shouldn't have come here directly." The Throne was, in a sense, the lifeblood of the entire Faerie Realm, and Jiang You's unannounced arrival made Morgan frown slightly. "Considering you've done so much for Baobhan Sith, I'll let it slide this once. Hurry up and tell me what you need."
"I'm here for just two things. One is to help you permanently solve the calamity that has plagued this Britain since its birth." Jiang You's gaze passed beyond the Throne, looking at the Great Hole behind it. At the bottom of the hole lay the corpse of the Great Cernunnos. The Lostbelt Britain was born because of it and would also end because of it (though not entirely, but close enough).
"You can solve it?" Morgan knew Jiang You was very strong and possessed extraordinary special abilities, but she didn't believe he had the power to deal with a world-destroying Curse. This was something deeply rooted since the birth of this land, inherited from the original sins of the fairies. If there had been any hope, she would have tried it long ago. This wasn't a problem that Spell could solve, let alone a magic idiot like Jiang You, whose understanding of Spell was only "it should probably be done like this." The only way to solve it was to make all fairies and even this world disappear. "Stop joking around."
"I know it's not easy for you to believe. Why not go and see for yourself?" Jiang You grabbed Morgan's wrist and pulled her directly down into the Great Hole.
"!!!" The battle-hardened Morgan attacked Jiang You without a second thought. That place was absolutely off-limits. Even though she was a fairy of the Paradise, different from the fairies of this land and untainted by sin, she still couldn't resist the tangible grudges down there. As for what Jiang You was thinking, it didn't matter right now. As long as she stopped this action, she would have plenty of time to figure out the situation.
But Morgan was horrified to find that she couldn't use any of her magical power at all. Jiang You seemed to have blocked her magical power release in some way.
Just as Morgan thought all was lost, she was surprised to find that the ink-black grudges actively avoided her and Jiang You, letting them proceed toward the center. At the speed of freefall, the two quickly reached the bottom of the Great Hole, where the corpse of the Great Horned God Cernunnos lay.
"It's really huge... So how did the fairies poison Him to death? How big was that cup? I thought we agreed to ignore the dose when discussing toxicity?" Jiang You and Morgan stepped on Cernunnos's body in a quite disrespectful manner. It couldn't be helped; if it weren't big enough, it couldn't have turned into the land.
"How... how did you do it?" Morgan no longer had the mind to care about Jiang You's rudeness. After thinking for a long while, she suddenly thought of a possibility, "Can your Noble Phantasm initiate a Duel against a corpse too?"
"That makes sense." In fact, it really could. Jiang You's Noble Phantasm could even initiate a Duel against abstract concepts. "But not this time. I'll explain the specifics later. Let's deal with the Great Cernunnos problem first... I plan to fuse Him into Fairy Tristan's Spirit Origin, letting her act as a miko to cleanse the grudges."
"Setting aside the fact that the Great Cernunnos is already dead, I will never... let Baobhan Sith do such a dangerous thing." Before Jiang You could explain, Morgan refused outright. She would rather let Britain be destroyed than sacrifice Fairy Tristan. It was just that her outward appearance didn't seem to be like that.
"Don't be so quick to refuse," Jiang You had already thought of a solution. "I have my own way to restore His consciousness. As for Fairy Tristan, do you still remember the Card she obtained after ringing the bell?"
"Of course I remember." Because it involved a prophecy, Morgan would absolutely never forget such a crucial matter.
"It's good that you remember. Fairy Tristan's swimsuit Spirit Origin in a certain Parallel World integrates the existence of the Great Cernunnos. Don't ask me why I have it, just know that it exists." FGO swimsuit characters do have reference prototypes, but not many. After all, there's no explaining how a water gun can blast out a curry rod stronger than the Holy Sword, but this also made it easier for Jiang You to handle the problem, because having a certain basis for existence meant that the resistance encountered when rewriting Reality would be much smaller. "The Great Cernunnos's grudges will obviously not be so easy to dissipate, and I can't replace Him in forgiving the Fairies either. However, He can be appeased, so Fairy Tristan is the best choice, and also the only choice."
"..." Because the Card served as evidence, Morgan was momentarily conflicted. "Then how are you going to do it? Cernunnos is no ordinary god. Making Him a mere Spirit Origin attachment to an ordinary Fairy has already gone beyond what Spell can achieve..."
Before Morgan could finish, she saw Jiang You knead the Great Cernunnos into a palm-sized plush toy.
Morgan: "???"
