I traveled through hundreds of worlds at once

"The contaminated Holy Grail?" Lily turned her head and looked at Yi Hui in confusion.

"The story starts from the third Holy Grail War sixty years ago..." Yi Hui explained to Lily the whole process of the Holy Grail being contaminated, while taking Lily to explore around the Holy Grail.

After listening to the story of the third Holy Grail War, Lily looked very strange, "Master? Since the Holy Grail is contaminated, why do you still want to participate in the Holy Grail War?"

"I participated in the Holy Grail War to improve my magic qualifications. This wish that can be achieved by technology alone can be achieved without the Holy Grail! The contamination of the Holy Grail doesn't matter to me." Yi Hui suddenly remembered something and asked back.

"Oh, I almost forgot, what is your wish for participating in this Holy Grail War?"

Lily heard this, tapped her chin with her white and tender fingers, shook her head and said: "Wish, I don't have any wish that needs to be fulfilled by the Holy Grail"

Yi Hui was stunned, "No wish? Then why do you participate in the Holy Grail War?"

"Because I heard you calling, Master!" Lily answered with a matter-of-fact expression, as if a young lady who had stayed at home for a long time suddenly heard someone outside calling her to go out and play, and she ran out.

"Well, you are more willful than me!" Yi Hui was speechless. No wonder he summoned Lily. It turned out that it was because of the two people's personality of going with the flow!

"Can you try to analyze this Holy Grail system? Extract some of the magic stored in it and purify it?" Yi Hui asked nervously when he saw this.

The complete evil of this world in the Holy Grail is too dangerous. It is estimated that even Medea, who has grown up, cannot deal with it, let alone Medea Lily. However, if only a part of the black mud is extracted, Lily, who is good at treatment and purification, and her treasures may be able to purify it into ordinary magic.

Lily frowned when she heard this, squatted down and stroked the rough ground, and fell into deep thought. Yi Hui looked at Lily nervously, holding his breath and waiting, for fear that he would disturb Lily's thinking.

After a while, Lily's brows relaxed and replied with a smile: "It can be done!"

"Yes!" Yi Hui said excitedly! Finally heard a good news!

"Then try it now!" Yi Hui immediately took out a lot of bottles and jars from the space without saying a word. These are all necessary materials for setting up large-scale magic.

"Master, where did you get this thing from? Space magic?" Lily stared at Yi Hui who was constantly taking out materials from the air with round eyes, puzzled. When she saw the candy before, she thought it was an ordinary magic, but she didn't expect it to be the most difficult space, and such smooth space magic was also very rare in the Age of Gods!

"I don't really understand this principle. It's a power that suddenly appeared one day. Just think of it as a small warehouse that I carry with me." Yi Hui's hand paused, and then laughed and said that he really didn't know the principle of personal space.

"Small warehouse! That's great, then I won't lack anything when I go out!" Lily cast an envious look, holding the magic wand and knocking in the big hole, constantly groping and figuring out the magic formula of the Holy Grail.

A few hours later.

"Success!" Lily, with a happy face, took a paintbrush and drew a huge and complicated magic circle on a branch of the Holy Grail.

Yi Hui, who was almost asleep when he heard the word success, was surprised and hurried forward.

"Master, wait a moment, I haven't started extracting yet!" Lily quickly pushed Yi Hui away. The magic in this holy grail is now all super dangerous curses. You have to be extra careful when opening it for the first time.

"Oh!" Yi Hui nodded quickly and pulled away.

"Then I'll start!" Lily took a deep breath and tapped the drawn magic circle with the round moon-shaped wand in her hand.

Buzz~!

A low humming sound sounded, and a charming deep purple light bloomed on the magic circle, emitting an endless curse, as if it was black mud flowing out of the dirtiest and most filthy swamp in hell.

Just seeing this black mud, Yi Hui's body couldn't help but produce a little resistance, as if he saw something extremely dirty, and instinctively wanted to stay away.

"It's so disgusting!" Lily also looked disgusted and quickly closed the magic circle. If there was more black mud, she would not be able to control it.

Lily stamped the staff in her hand, and the black mud that exuded a vicious curse condensed into a fist-sized black magic crystal under a magical force.

"This is the evil of this world!" Yi Hui walked forward curiously. The evil of this world that was made into a magic crystal had a stronger sense of vicious curse.

"Master, there is only one last step!" Lily reminded, and then the magic wand in her hand touched the black mud crystal.

"PainBreaker!" (All defects must be repaired!)

The tall staff instantly flashed with white light, illuminating the dark underground cave. Yi Hui's eyes were almost blinded by the sudden white light, and most of the magic power in the magic circuit was instantly drained.

After a while, the white light disappeared, and Yi Hui's vision gradually recovered. The black magic crystal in front of Lily also turned into a blue pure magic crystal.

"Success!" Yi Hui looked at the magic crystal with joy. The plan was successful so quickly! Could it be that he could complete his goal early in this Holy Grail War and just sit back and watch the show!

"Yes, it's done. This difficulty is beyond my expectation!" Lily picked up the purified magic crystal and shook her head.

Just purifying the curse of the black mud consumed a lot of her magic power. If she wants to continue this process to accumulate enough magic power, it will probably take at least ten days or half a month.

"Ten days, almost half a month!" Yi Hui touched his chin after hearing Lily's answer. Generally speaking, the duration of the Holy Grail War rarely exceeds seven days, and the Holy Grail War that lasted for half a month has never happened. Lily has no fighting power, so it is still a bit troublesome to delay it for a few more days!

"Can you summon an extra Servant?"

If he can analyze the Holy Grail system and summon another Servant, plus the Emiya Kiritsugu he contacted before as an external aid, it is not impossible to delay the Holy Grail War for a few more days.

Lily shook her head: "Master, now all the Servants for the Holy Grail War have been summoned. If you want to summon additional Servants, you must analyze the huge spell that constitutes the Holy Grail. If I want to analyze it, it will take a long time!"

"The goals conflict!" Yi Hui sighed.

There is no way to summon new Servants, so he can only do it himself.

"Master? You are not thinking about extending the Holy Grail War!" Lily saw that Yi Hui's expression was a little wrong, and she couldn't help but be surprised.

"As long as your thoughts don't slip, there are always more solutions than difficulties. There was no Holy Grail War that lasted half a month before, but it doesn't mean there is no Holy Grail War now." Yi Hui replied with a smile. As long as he can guide the Tyrant, let alone let the Holy Grail War last for half a month, even if it lasts for a year, he will find a way to complete it!

"Master! This is too dangerous! We are already weak. If we go out and mess around, we will be easily killed by other masters!" Lily hurriedly advised.

"Don't worry, I know my limits and won't put you in danger, Lily!" Yi Hui patted Lily's head to comfort her, and then took Lily's hand again and led her out of the cave.

Since they were group C, they naturally chose Liudong Temple as their residence, which was close to the Holy Grail. In the early stage, there were very few people who came to Liudong Temple because it was dark under the lamp.

Lily, who had transformed into a spirit, knocked on the door of Liudong Temple. Yi Hui planted hints in the monks in Liudong Temple with two hint magics, making them think that they were the residents of Liudong Temple, and found two rooms to stay in.

"Yi Hui was like a full-time nanny. After tidying up Lily's room skillfully, "Lily, you have worked so hard for so long, you should rest quickly!"

"Master, you should rest early too!" Lily held the staff and looked at Yi Hui who was carefully tidying up her bed. Her favorability increased a lot at once. It felt pretty good to have a master who was willing to make her bed.
