Click, click.

The crisp sound of leather boots stepping on the steps made of unknown materials reverberates through the long tunnel.

A pale yellow light emanated from the lampshell in Robin's hand, illuminating the surroundings, but instead of giving people the slightest feeling of warmth, it set off an indescribable coldness.

Maybe it ended too quickly, or maybe she was completely attracted by the history she was about to discover, and the black-bellied woman didn't notice that a battle had just taken place above her head.

And exploring alone in this ancient tomb, Robin's face did not show the slightest nervousness and fear, but faintly revealed a sense of excitement.

It is not known how deep this underground mausoleum was dug, but after Robin walked cautiously for a long time, he was blocked by a door.

It is a strange gate made of unknown materials, with many inscriptions engraved on it, and it reveals a gorgeous feeling in its simplicity, which is quite extraordinary at first sight.

Robin tried to push hard, but the door didn't move.

"Is there some mechanism?"

Robin pondered for a moment, searched left and right, and then found a very inconspicuous multi-layered turntable and a button on the stone wall next to it.

The turntable is divided into nine layers, each layer and each circle are engraved with different symbols, and it is not difficult to see that this is a combination lock.

And as long as you can change the password correctly, you may be able to open the door.

"It's hard to do now......"

Robin frowned slightly, she really didn't expect that there would be such a complex mechanism in the prince's mausoleum.

"I'm pretty confident in codebreaking, but I don't have time to play puzzles here. ”

Obviously, he is only one step away from the truth, how can he be blocked by such a broken door?!

(Am I going to open this door with violence?)

Turning her head to look at the hateful door, the intellectual beauty looked tangled.

If it weren't for the last resort, Robin really didn't want to wreak havoc in the historical sites, after all, she herself was the one who hated disrespecting history the most.

What's more, Robin doesn't think he has the destructive power to tear down this door that looks very strong......

"Alas~~~ It would be nice if Sherlock was here. ”

Robin was helpless, she exhaled lightly and muttered to herself, a pair of blue and black beautiful eyes sparkling.

If the sorcerer is here, there must be a way.

A certain black-bellied woman thought so.

Followed by......

"Is there anything you want to call me? Robin. ”

A familiar, magnetic voice rang out from behind Robin.

The voice was soft, but in the ears of this black-bellied woman, it was no less than a thunderclap.

？？！！

Robin turned around quickly, even if he was as calm as her, he was really startled by this sudden voice at this moment.

"Sherlock?!"

After seeing the appearance of the visitor, especially the iconic silver-rimmed eyes, Robin's beautiful face was stunned for a moment, and then he smiled and said:

"It's been a long time, Sherlock. ”

"Long time no see?"

Sherlock looked at Robin a little strangely, and gently pushed his glasses: "No, haven't I only been away for less than three days?" ”

"In less than three days...... "Robin blinked and muttered softly.

(But why, I think he's been gone for a long time...... ）

Feeling the familiar smell of a glasses beside him, that extremely reassuring feeling, Robin's heart couldn't help but become calm.

(Is it because I'm used to it?)

Looking deeply at Sherlock, Robin stopped thinking about the question and didn't ask what a certain glasses had been through these days, she raised her hand lightly and pointed to the door in front of her.

"Let's talk about some things later, Sherlock, this gate is followed by the prince's tomb, can you open this gate?"

"This door?"

Sherlock stepped down from the door in front of him, turned his head to look at the mechanism on the wall, muttered for a while, and said:

"Looks like this door requires a password to open. ”

As he spoke, Sherlock nudged his glasses and raised his hand to press the button.

"Don't ......"

Robin was about to stop it, because based on her years of archaeological experience, it would be very unwise to trigger the mechanism without entering the correct password, but then ......

Click, click......

With the sonorous sound of mechanical operation and the scattered dust, in the stunned gaze of a certain black woman, a glimmer of light shot out from behind the door, and then the heavy door slowly opened!

This door is not locked!

"Sherlock, you ......"

Robin looked at Sherlock in confusion, but after meeting Sherlock's serious eyes, Ice and Snow was as smart as her, and she instantly realized the problem.

There are generally two main reasons why the door is not locked.

The first is that the owner did not have a lock in the first place, and the so-called lock is an ornament, and this reason is obviously not valid here.

And this second type is......

"Someone has been here before, before us. Robin whispered.

Sherlock nodded and said, "Yes, and the person who opened this door definitely has a lot of information about the Seven Star Sword, so it is very likely that he is a native of Lost Island." ”

(Actually, according to the information I knew before, the lockpicker is probably the man...... ）

Sherlock pondered in his mind.

The Oswald family's plans, the real masterminds, the connection between the war and the Seven Star Sword, one mystery after another has been solved by Sherlock, and he has made a corresponding plan to deal with it.

But Sherlock is still at a loss for the biggest mystery.

(What the hell is the Seven Star Sword, and where is it sealed by the Prince?)

With this question in mind, Sherlock and Robin walked through the gate and into the prince's resting place.

"This is the prince's mausoleum?"

Sherlock pushed his eyes, and the scene in front of him was a little different from what he had imagined.

It's a huge underground palace, and while it's nowhere near the funeral hall in Alabastan where the historical texts are buried, it's also very empty.

The roof of the dungeon is covered with an ore that emits light, so even if there is no sunlight, it is still as bright as day.

On the stone walls around the underground palace, there are huge colorful murals, and I don't know how these colors have been preserved for thousands of years.

These murals were drawn around the entire dungeon, and as soon as Robin entered, he was firmly attracted by these murals and looked at them intently.

In the center of the dungeon are seven giant cross swords about ten meters long, forming a sword array, the shape of the sword is similar to the cross sword in Maya's hand, except that a dark red gem resembles an eye pupil is inlaid in the sword grid.

Half of the blades of these seven giant swords are straight into the ground, and the other half is engraved with inscriptions in ancient characters, as if they were seven sword tablets.

Relying on his half-baked level of ancient writing, a certain glasses could barely translate the inscription on it.

"Greed, fear, anger, hatred, jealousy, despair, arrogance...... Seven negative emotions. ”

Sherlock muttered to himself, his dark eyes narrowing slightly under the lenses.

(Is this the ability of the Seven Star Sword?)
