As soon as he heard Mayor Finch's words, Lukka immediately understood that he had really found the right place this time. But after all the mayor had said, there was one thing he still hadn't figured out.

"Mayor Mare, what's the relationship between that ruin you mentioned and collecting information about humans?" Thea interrupted Finch, and it seemed that Lukka was not the only one who had questions.

"Kid is in a hurry, haven't I finished yet?" said Mayor Finch, shaking his head.

"Then you hurry up and say, wait for the tea and drink it later!" Thea unceremoniously snatched Finch's teacup and set it aside.

The mayor looked at her captain helplessly, and Lukka quickly put on an expression of "what can I do?" to show that the bear child's behavior had nothing to do with him.

In the face of the unreasonable silver-haired little girl, and the prospective guardian who had been pampering her, Mayor Finch gave up his resistance: "Alas, forget it, I continue! Although I can't enter the underground part of the ruins, there are still some petroglyphs left on the ground, and I have drawn the patterns on it in the same way!"

So saying, Mayor Finch called over to a servant and ordered, "Go to my study and bring the facsimiles from cabinet three." ”

It wasn't long before the servant returned with a large pile of papers that were over his height, and Lukka quickly got up and helped remove the teapot from the table to make room for the pile. Although the maritime trade is not very developed, the paper-making skills here are better than those of the Sunset Islands, and the paper is soft and white, which is no less than the product of modern industry.

Mayor Finch opened one of them, but the drawing on it was very rough and rudimentary, and it looked like the graffiti of a two- or three-year-old child.

"I painted the petroglyphs as they were, and the first thing to do for this kind of reproduction is that it is exactly the same, and it doesn't matter whether the painting is good or not. "Finch is a little embarrassed, his own art level should be much higher than that.

"Well, I understand. Lukka nodded, looking at the patterns carefully, "You just said that it is a prehistoric relic, then these paintings should also be painted by uncivilized humans many years ago, of course, they are not as good as the current painting masters." ”

"You're on point!" Finch clapped his hands suddenly, "These paintings are all prehistoric 'humans'!"

Lukka realized what he had overlooked, in his mind, it was normal for humans to appear in petroglyphs, but this was a boiling sea, and there had not been many traces of humans here for thousands of years.

"Especially here, you see," Finch picked out one of the scrolls and opened it, "this human, with a staff in his hand, seems to be opening the underground entrance to that ruin!"

Lukka looked at the place of his finger and said, stunned for a moment, and his hand couldn't help but reach for a touch on his waist. The Amethyst Staff was too spacey and conspicuous on his back, so he used a small illusion before going ashore to turn it into a trumpet staff and hang it on his belt.

Although the painting on the picture is exaggerated in proportion and childish, the long wooden pole and the huge purple crystal are clearly drawn, if it weren't for the fact that the amethyst staff and Luca's spiritual space have been integrated, he knew that his staff was still hanging on his belt when he touched it, and Lukka would have thought that this staff had played time travel again.

He wanted to study it more closely, but Mayor Finch quickly put all the scrolls away.

"I know you're interested, but these aren't things that can be shared casually!" His small, round brown eyes twinkled, clearly thinking of something.

"Don't be so stingy, I'm just going to take a look, and I won't take it. Out of the corner of his eye, Lukka glanced at the closed mouth on his shoulder, and the parrot was nodding slightly at him. The patterns on these pieces of paper don't need to be copied at all, and Shut Up is now almost a moving scanner, just let it look at it once, and everything will be solved.

"No, no, no!" Mayor Finch didn't take it, but got closer to the truth, "Who knows if you humans have never forgotten it? ”

"I know!" Lukka smiled wryly, "You can make an offer, how many silver coins?"

"How can that kind of thing reflect the value of these facsimiles? Now, as long as you agree to my conditions, not only will this set of facsimiles be given to you, but I will also tell you the coordinates of the ruins, and if you are interested, you can also go there for a field trip! No, I can even take you myself!"

Lukka came to the Boiling Sea, and what he wanted to do was to investigate the ancient ruins and find out which ones might serve as passages between several worlds, so that they could be blocked. Now there was a clue that could not be more obvious in front of him, and he could not let it go.

"Tell me, what's the condition?" Lukka planned to salute first and then soldier, if the other party's conditions were really unacceptable, it would not hurt to use a little trick.

"I've said so much, don't you understand?" said Mayor Finch, whose mouth was dry, and he turned back to find tea, only to find that the teapot had been placed far away by Luca, and the servant trotted all the way back to him.

He took a sip of his tea and continued, "You've seen the pattern on that picture, the human on it is clearly opening the entrance to the underground passage, and a series of movements are drawn on it.

"I copied an identical staff in that place, as it was, and tried all sorts of things, but I couldn't open the entrance. I analyzed and analyzed, it must be a racial issue, and the people who do these things above are all human beings!

"You don't have to worry, it's still unknown what lies beneath the ruins, and I won't let the first-time guests, such a rare race, do such a dangerous thing.

"All I want is to ask one of you humans to stay in my town for a few days, as a favor to gather basic information about your race, and if you are interested in telling me some anecdotes about your species, it would be better.

"How's that, this condition, it's not too much, right?"

Lukka asked, "How many days did you say you would have to stay, but for how long?"

"Of course, the longer the better!" Mayor Finch said as he observed Luca's face and adjusted the number, "At least half a month!

Lukka lowered his head and thought for a while and said, "Seven days is acceptable, but whoever stays here to help you must be designated by me!"

"Huh?" Finch was a little disappointed, "and who are you going to let stay?"
