"This is 'All the World's Evil'... the magical power after being contaminated in the Third Holy Grail War."
Rin Tohsaka crouched in front of the Lesser Grail, looking at the black mud continuously seeping out from the Grail, couldn't help but frown, feeling instinctive fear and disgust toward this thing.
Although she had known long ago that the Grail's magical power had been contaminated, Rin Tohsaka had originally still thought that perhaps she could research a method from it to properly fulfill wishes.
After all, All the World's Evil would only use "twisted methods" to fulfill wishes for people, but if the wish she made didn't give the Grail a chance to twist it, couldn't it be properly fulfilled?
But now Rin Tohsaka had given up hope on this idea—after seeing the black mud, she understood that this thing couldn't possibly give her a chance to exploit loopholes.
If she had tried to make a wish for "Zuke to be able to live in this world as a human," who knows what the wish might have been twisted into in the end. It might even cause harm to Zuke.
On the other side of Rin Tohsaka, Sakura Matou was also looking down at the black mud in the Lesser Grail—unlike Rin Tohsaka, Sakura Matou didn't feel from beginning to end that there was anything wrong with the black mud.
In her view, as long as it could make Zuke stay in this world, any price was insignificant. Even if the wish was fulfilled in a twisted way, as long as it was fulfilled, there was no problem.
After all, unlike Rin Tohsaka, from the moment Sakura Matou was sent to the Matou family by Tokiomi Tohsaka, she had no future. Zuke was the one who saved her, the only person worthy of her attention.
Of course, although this thought hadn't changed, Sakura Matou now wouldn't use this Grail filled with black mud to make wishes.
On one hand, the Grail was obtained by Zuke. On the other hand, she had already learned from Waver that Zuke could now freely traverse between different worlds.
In other words, even without using the Grail to make wishes, Zuke could return anytime—for Sakura Matou, that was already enough.
"Then, I'll leave the Grail to Zuke-san to handle."
Waver naturally didn't dare step forward to touch the Grail. After all, the black mud from the Grail was already starting to overflow. He couldn't be sure whether touching the black mud would have any effects on him.
Seeing this, Zuke also nodded, then walked over and grabbed the Grail placed on the ground—the black mud in the Grail seemed to sense something and began churning.
But Zuke completely ignored it. The "Black Bird: Requiem" behind him also reached out its hands, beginning to absorb the black mud overflowing from the Grail.
Having had experience converting black mud into magical power before, this time Zuke no longer held back. He let "Black Bird: Requiem" begin frantically absorbing the black mud, planning to empty the Greater Grail's magical power in one go.
The Greater Grail now had no magical power left. As long as this Holy Grail War ended, the Greater Grail would begin accumulating magical power again.
Not until 60 years later, when enough black mud magical power had accumulated, would it open the Holy Grail War again.
However, Waver clearly wasn't planning to let Fuyuki City's Holy Grail War continue—because the magical power accumulated next time would still be "All the World's Evil." This wouldn't change.
To prevent someone from truly making twisted wishes through the Grail, Waver had already decided to dismantle the Grail afterward. Zuke had agreed.
While using "Black Bird: Requiem" to absorb the black mud, Zuke also wasn't idle—he sank his mind and opened the system's mission panel.
This time the Grail had genuinely manifested, already connected to the Greater Grail. Even black mud had started seeping out. The system couldn't possibly say this didn't count as obtaining the Grail, right?
If the system insisted he had to kill all the other Servants before it counted as obtaining the Grail, then Zuke truly had no recourse—he really didn't want to kill Sitonai just for a mission reward.
Fortunately, things hadn't reached that point. The system's response was still normal.
[Current World: Fate/Stay Night][Main Quest: Obtain the Holy Grail of the Fifth Holy Grail War][Player Doghead's Power Synchronization Status: 100%][Please do your utmost to advance the main quest and unlock power synchronization][Congratulations Player Doghead for successfully unlocking 100% synchronization in the Fate/Stay Night world!]
The moment synchronization reached 100%, Zuke also gained all the power he had obtained in this world—but unfortunately, Zuke didn't really have much progress in terms of strength in this world.
The TYPE-MOON world couldn't provide much boost to his strength anymore. Zuke's completion of this mission was mainly to obtain the mission rewards.
So Zuke shifted his gaze to the portion concerning this main quest's rewards.
[You may select 2 rewards from the following to take out of this world][1. Heroic Spirit Summoning System (One-time Usage Rights)][2. Mordred][3. Fuyuki City Leyline]
After seeing these reward options, Zuke's first reaction was—you can select 2 rewards to take out of the world?
Zuke had originally thought that increasing the number of rewards would be unlocked during some future achievement reward, but he hadn't expected that despite not unlocking new achievements recently, the number of rewards still increased.
Although he was very puzzled about why this mission's rewards could select 2 items, overall it was a good thing. Zuke didn't think too much about it for now.
Immediately after, Zuke's second reaction was—why was there such an abstract reward as the Fuyuki City Leyline?
The Fuyuki City leyline was a necessary condition for constructing the Holy Grail War. The Tohsaka family could become one of the Three Founding Families of the Holy Grail War precisely because they were the managers of Fuyuki City's leyline.
In some parallel world works, the Holy Grail War had also been seized and constructed in other regions.
However, because the leylines in other regions were far inferior to Fuyuki City's leyline, the Servants' strength was also greatly reduced.
From this perspective, Fuyuki City's leyline was indeed the most suitable for constructing the Holy Grail War. If Zuke took this thing away, combined with the Three Founding Families' Grail materials, he could even build a Holy Grail War himself.
Of course, apart from the TYPE-MOON world, other worlds didn't have the Throne of Heroes. Even if he built it, he probably couldn't use it—Zuke could only play with this system in other parallel worlds of the TYPE-MOON world.
"Although the Fuyuki City leyline seems to have no great use... there's nothing else to choose anyway."
Zuke thought for a moment, and in the end, unsurprisingly chose the "Heroic Spirit Summoning System" and "Fuyuki City Leyline" as the two rewards.
Because the "Mordred" reward didn't need the system's help at all. Zuke could directly take her away using "King's Army."
