After a day of reading the literature, Roy paused his borrowing and began to ponder the magic of this world.

The Great Source here is very active, and the magic power is called "Mana", and those who use the magic in their body through the "gate" are called magicians, and those who use Mana in the air are called elven warlocks.

To paraphrase the Moon World, it is a small source magic that uses small source magic through a magic circuit, and a large source magic that uses large source magic.

Dayuan is so active, and people with talent and fate can also communicate with the micro-elves, which is really envious of the modern magicians in the Moon World.

This environment is actually very suitable for a god-generation magician like Medea, who secretly revealed to Roy after meeting Rozval that with her experience as a magician, she can defeat it with full firepower.

Speaking of which, although Medea, a god-generation magician, is very capable, she was very strained in the Fifth Holy Grail War.

In other words, in the entire five wars, most of the servants were affected by various influences and pulled their hips.

Saber Artoria is an incomplete summoning of a layman, resulting in a magic supply circuit that cannot be connected, unable to supply magic power normally, all attributes have decreased, and even the level of the Noble Phantasm has decreased.

Lancer Cú Chulainn changed the master, and was ordered by the Command Spell not to go all out, but to retreat at the right time.

The Rider Medusa contract was handed over to the temporary master.,Shinji Makiri, who doesn't have the slightest magic power.,Long lack of demons.,All kinds of killings in seconds.。

Assassin Kojiro Sasaki can't even leave the mountain gate, and he has turned from an assassin to a "goalkeeper".

Berserker Hercules lost his mind due to madness, and could only rely on instinct, and was also targeted because of divinity.

Caster's Medea is even more miserable, the oil lord Atram Gariasta does not trust the "witch", and uses a spell to order her not to use the treasure on him, and also plans to kill Medea in exchange for another servant.

After being killed by Medea, the new lord Soichiro Katsugi found by Medea is an ordinary person, and the next thing is that he lacks magic power for a long time and can't play his combat effectiveness.

Now that Roy is a qualified master, and in the active world of Dayuan, Medea's strength is far greater than the full state during the five stations.

Coupled with Roy's various heroic abilities, Roy and Medea can sweep through the entire Rozval Mansion, unless Parker can't think of destroying the world, or Ram's severed horn grows again.

After Roy quickly recorded the various knowledge in the forbidden library, he felt that he had benefited a lot, and he thought about it.

"Now the most important books and documents have been recorded, you can go back and read slowly, if you want to really use it, you have to analyze the magic foundation first, you can't be in a hurry.

In addition, it is the 'return of death' ability of Caizuki.

This is the most important opportunity to upgrade the treasure of the 'nursery rhyme', if I can analyze more about how the jealous witch in this world rewinds time, it can even give me a glimpse of the second and fifth methods. ”

The second and fifth methods can be in contact with time, if you have to choose one, in fact, time travel can be included in the parallel world observation of the second law, through the world, to a certain extent, it can also be regarded as a parallel universe with different timelines, but Caiyue Pleiades is not traveling through parallel worlds, but really changing the timeline.

As for Aosaki Aoko's use of the fifth method to interfere with time, it is through the fifth method and her "destruction" attribute that the control of the timeline is achieved by means of "destroying the timeline", not that the essence of the fifth method is the timeline.

Either way, time is one of the most mysterious forces in the world, and Roy is naturally very interested.

What makes people tangled is that if you want to analyze the 'return of death' more and get inspiration and principles from it, you have to have more material to analyze.

In other words, it is necessary to let the nursery rhyme bookmark implanted in the dream of Caiyue Pleiades record the death and return of Caiyue Pleiades several more times, and experience every timeline change.

This also means that Caiyue will die a few more times.

But Roy is not the kind of magician who exterminates humanity, he can deal with the enemy, but the people in his own camp, once he identifies them as the same group or common interests, he will seek a win-win situation, so he will not kill Caiyue for a little record.

"Hey, it's really tangled, who made us a kind-hearted magician."

Roy sighed while preparing to go to his guest room, at this time, Cai Yue, who was wearing a deacon uniform, came over with a mysterious look and whispered to Roy:

"Roy-kun, I've figured out who killed me!"

"What?"

"I've been here twice since I got to the mansion, and the last time I've been sure it was Rem who did it. At that time, you told me that if the investigation came out, you would come to you and find a way, so I came. ”

"......" Roy was speechless. Am I so cold-blooded, not only did I watch Cai Yue die twice in the two timelines, but I also asked him to find the murderer by himself.

I thought I was soft-hearted.

"Pleiades, calm down, go to my room, you tell me what happened, and you also know, I have stored a record in your dream, although I can't get all the information, but I can get an approximate message, and my message from other timelines, you let me figure out the situation first."

As one of the few people who can open up about the 'Return of the Dead' event now, Natsuki trusts Roy very much, and immediately follows Roy to the room and begins to talk about the experience during this time.

It turned out that after coming to the mansion, Natsuki died twice.

The first time was to die of weakness in his sleep due to a curse in his sleep, but Natsuki didn't know why, and Roy knew that he should have fallen under the curse of the Warcraft, indicating that the Warcraft Envoy had come to avenge Elsa.

After the time is rewinded, the preservation point of the mansion this time is different from the original book, it was when Natsuki was wiping the vase, he quickly notified Roy, but Roy in that timeline did not directly reveal the matter, but told him that he had no clue, and asked him to tell him after finding the prisoner.

As a result, on the one hand, because every time death returns, the "witch's aftertaste" of Natsuki Pleiades will increase, which leads to a high degree of suspicion among Rem.

Coupled with the fact that he was too active in the investigation, so that his behavior was even more suspicious, Rem took matters into his own hands and took advantage of the night to kill Natsuki Pleiades, who desperately saw Rem's face before he died, and returned to the vase in a blink of an eye, and then hurried to find Roy.

"It's Rem's hand, you can help me analyze and analyze, why did Rem kill me?" Caiyue asked anxiously. onclick="hui"
