"You mean, the last piece of crystal was found?" Looking at the housekeeper who came to report, Lin Xiao asked with a look of surprise.

"Yes, sir, Mr. Vernal has sent the fastest ship to bring the crystal back. The butler replied.

It's not easy.

Originally, after getting the fourth crystal, he was ready to find out the last one in one go, and then unlock the secret of the crystal.

Unexpectedly, after spending a lot of manpower and material resources, three full months have passed, and there is no news.

Not to mention crystals, not even a single remnant has been found.

It seems that in the entire Golden Island, except for the remnant settlements of the four main cities that have been discovered, there are no remnants.

The whole crystal is complete, except for the last part.

One piece is missing, which means that it is incomplete, and no matter how powerful Xiao Shirley is, she will not be able to finally study the specific role of the crystal. And, even if you know the role and a part of it is missing, you can't play the role.

Three months, with no gains, was enough to extinguish the initial enthusiasm.

In addition, the most important thing in the Immortal River Territory is development, if the search for a crystal that is uncertain whether it exists or not, and the development of the Golden Island is slowed down, the gains will outweigh the losses.

So.

Lin Xiao made a difficult decision, ready to stop continuing the meaningless search.

Unexpectedly.

At the last moment, there was good news.

The last remnant settlement of the main city was found.

Moreover, through interrogation.

After summarizing the information confessed by all the remnants of the main city's settlements, and corroborating each other, a shocking secret gradually emerged.

The dungeon, real.

Moreover, the legendary underground palace is a forbidden place in the era of the main city.

Approximate location, just below the ruins of the main city on the Golden Island.

But where the specific entrance is, how to open it, and the answer can only be found from that crystal. Because, in the information obtained, what is associated with the underground palace is basically a red crystal.

Of course, everything is unknown how big that legendary dungeon is and what exists inside.

Perhaps, only by really opening the door of the underground palace and entering it can we unlock all the secrets buried in history.

......

When the last crystal was sent to the rune laboratory, the girl just said to him excitedly through simple experiments and observations: "Brother, the rune combination on the crystal is very complete, it is a high-level unlocking rune combination, if I am not mistaken, this crystal should be a key, a key to unlock the void rune lock." ”

"Void Rune Lock?" Lin Xiao was a little puzzled.

"Yes, the Void Rune Lock is a kind of rune lock engraved in the void, there is no specific carrier, at least it needs a rune master to depict. Moreover, the Void Rune Lock, after being depicted, can automatically conceal and lock an area inside, revealing the appearance of being indistinguishable from the rest of the surrounding area. The girl explained.

"I see. ”

Lin Xiao nodded, to put it in layman's terms, it was similar to the legendary illusion.

On the surface, it doesn't make a difference, but if you can look through the barrier, you can find the truth hidden behind.

This kind of void rune lock is to put an area as if it were a lock, everything inside is hidden, if there is no key, not only can the anomaly not be found, but everything that is covered inside cannot be seen.

At this time, the girl continued: "Brother, because the crystal is broken, the rune combination on it has been cut off, and it needs to be repaired before it can play a role. ”

"How do you fix it?" Lin Xiao asked.

"I need some runic materials, I'll sort out the list later. The girl said, "As long as the materials are ready, I will soon be able to connect the rune combinations and reassemble them into a key." ”

"Well, that's good, I'll prepare the materials right away. ”

Just do what you say.

Before that, because the crystal was broken, there was no way to study the specific effect, so I had to wait.

Right now.

After spending a lot of manpower and material resources, all the crystal fragments have been gathered, and if you can't find out the secret hidden behind the crystal, all your efforts will be in vain.

This is unacceptable.

In addition, Lin Xiao was extremely hot about the forbidden land of the underground palace left over from the main city.

Since it is a forbidden place, and it is also a forbidden place left over from the ancient main city, how can the things that exist in it be simple.

Perhaps, another island treasure.

Moreover, with the huge strength of a main city, it is not as simple as some gold coin materials. Perhaps, you can get epic treasures, rare blueprints, piles of Yuan crystals, and a huge number of cheats inheritance......

When Lin Xiao was thinking about the dream of the treasure of the underground palace.

Thanks to the abundant number of territories and the wide variety of Yuanli material reserves, most of the materials in Xiao Shirley's list can be found from the territory treasure house.

The few others can also be traded through trade fleets.

The rest is just time.

Ultimately.

Less than ten days later, a crystal crystal that was more than the size of a palm, crystal clear, was restored.

The whole is seamless.

The originally shattered crack also disappeared after the rune combination was connected, like a crystal that was originally intact, which was extremely magical.

Lin Xiao felt that even this piece of crystal was an amazing material.

At least, he's never seen it.

The generosity of the ancient main city can be glimpsed from a crystal key.

From the relics of Master Andy at the beginning, as well as some ancient books that I had seen in my previous life, it was recorded that the more time went on, not only the number of main cities was more, but also the resources were more.

What seems to be a precious material now, in the past, may have been just a big road cargo.

But.

Lin Xiao had another judgment in his heart.

He has been a human being in two lives and has experienced two lord selections, but he has a lot of speculations about the star world and the secrets behind it.

Perhaps, the earth humans are not the first beings to enter the star world for lord selection......

Perhaps, the resources of the star world have been consumed because of the many lord selections......

Perhaps, the lord selection is really just a lord selection, and the star world is just a selection world......

It's just that.

Since the selection, that mysterious voice has never sounded, like a program that has been set up a long time ago, and after it is finished, it will completely disappear.

So, it's all speculation.

It is not possible to determine whether it is true or false.

Once, too, he thought.

What kind of existence does the star world really have?

Where did it come from?

All of this will not be answered after all.

Perhaps, one day, if the fairy river leader really becomes a city in the sky, as the legend says, it will only know the ultimate secret when it transcends everything.
