"Number 11273 had completed an A-Class Side Mission and received 50000 exchange points."
"Number 11273 had completed all Main Quests and could choose to return to the Main God Space at any time, or remain in the Instance World."
"Choose to return to undergo mission evaluation and claim rewards."
"Choose to remain to stay in the Instance World for another three days."
These system notifications only appeared after Fang Li had resolved the issue of the Greater Holy Grail.
After all, Fang Li's Side Mission was to reclaim the Greater Holy Grail from the Floating Garden intact and prevent Amakusa Shirou Tokisada's wish.
If he did not first resolve the problem of the Greater Holy Grail, which had already been modified and was constantly fulfilling its function of attempting to draw magical energy from Earth Veins across the entire world in order to universalize the Third Magic, then even if he reclaimed the Greater Holy Grail and defeated Amakusa Shirou Tokisada, it would not count as preventing Amakusa Shirou Tokisada's wish.
Only by resolving the wish Amakusa Shirou Tokisada had made could the mission be considered complete.
This also illustrated, from another angle, just how difficult an A-Class Side Mission was.
After all, Amakusa Shirou Tokisada had already made his wish to the Greater Holy Grail, and that wish could not be revoked.
Thus, Fang Li had used the Magic Items stored inside the Fairy's Cloth Bag, finding a suitable item to solve the problem.
After that came the matter of who the Greater Holy Grail would belong to.
The Side Mission required him to reclaim the Greater Holy Grail, not obtain it.
Now that the mission was complete, the Greater Holy Grail was no longer relevant to Fang Li's mission.
Of course, it was only irrelevant to the mission.
