Shut up and couldn't help but fly down from the chandelier and scratch at Art's hair.

"Okay, okay, I said it's not okay to be simpler?" Art covered her head with her hands, "The current location of the Guide Stone is in the Umeze Islands, you can check the specific location on the chart yourself, that place is quite famous." ”

"How good did you say that?" Lukka nodded in satisfaction.

"What's good?" "He's talking about 'archipelago', archipelago!

Yatel waved his hand: "It's not so troublesome, although there are dozens of small islands in the Meze Islands, only the largest one really has residents, you just go there and ask." ”

"Don't worry, when did you send that stone?if we want to get it, do we need any proof?" Luca's concern was not unreasonable, in the field where he and Arte were now, time overlapped like a photo on an album, even if it was something that Arte had just sent, it could have been sent to the boiling sea hundreds of years ago, he had to ask clearly.

"Don't worry, I'm keeping an eye on the time. "The time when the Guiding Stone was delivered to the Umeze Islands, according to the coordinates you are in now, is fifty years ago, and I have not heard of it being taken away again. ”

"So can you be sure it's still there?" Lukka was not reassured.

"Eighty percent, I didn't keep staring at it. Arte said and groped in his pocket for a long time, pulling out a round stone slab that was not yet the size of a palm.

"What is this?" asked Luca.

"The credentials you want. "Att, the slate slipped into his hand.

The gray slab is about ten centimeters in diameter and is made of the most ordinary gray rock, with no pattern on it.

"What's the difference between this and broken rocks on the beach?" Shut up and squinted his eyes, "Don't you think it's too easy to copy with this as a proof?"

"Why? This is a credential that can only be used by mages. ”

Art said, poking his wand at the surface of the slate, which lit up with dim silver dots as his mana flowed through. These points of light were like life, and they connected with their companions next to them, finding their place on the stone slabs. Finally, a circular pattern of silver dots of light appears on the slate.

"It's not a circle. Luca wasn't so sure.

"Of course not," said Art, "this pattern reflects the most primitive storage state of the caster's mana flow, which is different for each mage, and in simple terms, it can be counted as a unique magical signature drawn by each mage with his soul." It is said that at the Academy of Magic, they use this method to prevent students from cheating on substitute exams. ”

Lukka took the slate and poured his mana into it.

Soon, his magic signature also shone on the stone tablet, several times brighter than the light that emanated from Art's hand just now, and the brightness of the magic clearly indicated the gap between the magic apprentice and the high-level mage.

Luca's motif is almost identical to Atte's in the middle, but the direction is markedly different on the periphery, the lines are not as rounded, and the turns are a little wilder.

"The signatures are all different in shape and brightness, can this certificate work?" Lukka asked.

"No problem, the inhabitants of that island don't know anything magic, they just need to see the glow. Yat said.

"What if there are other mages pretending to be them?" Although Lukka believed that he was the only resident mage in the sea world, he had to consider this possibility.

Art replied, "This slate was made by you, it belongs to our family, and it is useless for a mage who is not related to us to be related by blood, no matter how much magic flow is injected. Even Principal Fez, he couldn't make it light up. ”

"Fez, which Fez, Selva, or the wrinkled old fellow?" asked Luca.

"You're kidding, Selva has been dead for hundreds of years, right? Of course it's the same professor Fez who taught you in the first place!" said Att.

Shut up and sighed on his shoulder, shook his head and said, "He can be the headmaster......?

"Is it foolish for the whole school to join him?" asked Luca.

Shut up and glared at him, turned away, and turned his tail at the equally unreliable father and son, not wanting to talk to them again.

"Nothing else, I'll go back first. Lukka stood up, facing this son out of thin air, and the longer he stayed, the more awkward he felt.

"No, didn't you hear what I just said?" "Art stepped forward and grabbed his sleeve, "I have two things to do with you." ”

Lukka scratched his head: "It seems that there is such a sentence, let's say, what else is going on?"

"It's easy, do you remember the book about giant circles?" asked Art.

"Remember, what's wrong?"

"I've been trying to study this book lately, but you didn't know when you put a seal on it. Yat said.

"You want me to break the seal?" Lukka asked, but he knew very well that he had never added any seal to the book so far.

Arte shook his head: "That's not necessary, as long as you tell me what type of seal was used at that time, I can do it myself, and it's not a complicated and advanced seal." ”

Lukka smiled and said, "You think very well, but I really can't help you with this matter, haven't you paid attention to the time of the seal?

"Really? I was negligent?" Atté scratched her head.

"And even if I knew what seal I was using, I wouldn't tell you. Lukka continued, "You don't go to the daddy of your own time, you have to come here and ask me, I guess, that seal is for you, do you think I will make trouble for my future self?"

Art still wanted to defend himself, but found that once Lukka found out the truth, he became extremely stubborn, so he had to wave his hand and said: "The last thing, the information I told you, about the boiling sea, you don't need to keep it secret, but about my identity, the future you, and everything that may be related to the future time, I hope you can keep it secret, and don't reveal it to your crew." ”

Lukka shook his head: "I can't do this, on my ship, there are not so many secrets. ”

Art hesitated for a moment and took a step: "At least, can you keep my identity a secret?

Lukka thought for a moment and replied, "Well, I'm not going to say that. ”
