On the sixty-ninth day of going deep into the dungeon, Rob and Loro finally reached the seventh level.

It was inhabited by powerful magical beasts, as well as terrifying traps and metal golems, and even with Bevinadette leading the way, the speed of the two slowed down.

Even Rob had to be careful here, the future Ultra Magister let go of his spiritual power to sense the danger lurking around, and Luo Luo also took out the vial of red primogenic gum from his bag, which was given to her by the ugly girl when he was in OGreene, and it can effectively isolate her own aura when applied to her body, even a ninth-order professional is difficult to find.

When the girl tried it on the sixth floor, although she didn't know how those metal golems searched for intruders, the good news was that the red gum was indeed effective against them, as long as the two of them painted this thing, even if they swaggered in front of the eyes of those metal golems, they would turn a blind eye, although the metal golems at the higher levels were stronger, but the mechanism of seeking enemies had not changed, so now was the time for the red glue to come into use.

On the second and third floors, Luo Luo and Rob can still find the footprints of a small number of adventurers, but after entering the fourth floor, there are no other adventurers, and there are only two people left in the whole world.

I don't know who designed and built this dungeon, tens of thousands of years have passed, the ecosystem inside is still very good, those artificial sun, moon and stars are tirelessly alternating in the sky, even in more than 2,000 meters underground, you can still breathe fresh air.

Almost everything from the outside world can be found here, whether it is mountains or rivers, hills or lakes...... It's as if the people who created this world wanted to take everything down on the ground.

The more he looked, the deeper Luo Luo's doubts became, if the creator of the dungeon loved the surface so much, why did he build such a place in this deep underground, and who were those towering Mithril walls resisting?

As if sensing what she was thinking, Rob explained, "This is the Origin Land. ”

"Huh?"

"This dungeon is the first dungeon in this world, and other dungeons were built after it. ”

"How do you know?" the girl wondered

"I once followed my teacher to explore a dungeon, and it was perfect, both structurally and structurally, but there was one thing missing from here. ”

"What's that?"

"Traces of failure. Robb paused and continued, "This dungeon was not built all at once, I found this from the first time I came to see the sewage pipes in the inner city, there are many traces of alterations in those pipes, and its designers have tried many times, some have succeeded and some have failed, and they have kept the successful part and improved on it...... In fact, it's not just those sewage pipes, everything you see here has the imprint of failure, those stars and rivers, the rising sun and the valley, every inch of land is the product of countless failures. ”

"They?" Lolo grasped the point of the sentence, "Do you mean that there was more than one person who designed and built this dungeon?"

Rob nodded, "Even with the technological level of that civilization, it is definitely not easy to build a dungeon, and it will take at least a few generations of wisdom. ”

"According to you, that civilization was once extremely strong, so why did they decline?"

"We're back here to find the answer to that question. His Excellency the future Magister replied.

"Is this answer important to us?"

"It's important, if my guess is confirmed to be correct, they should have a solution to your problem. Rob said, however, there was one more thing he didn't say, and if his guess was correct, humanity might well be facing the greatest crisis ever.

Luo Luo sighed, but her focus was not on this, and after a pause, the girl said, "Now, these days, I occasionally think about it...... It might be nice for us to live here, wouldn't it take hundreds of years to conquer a dungeon, we only need to live a few floors higher, so that no one will disturb us, we can spend the rest of our lives quietly, and we won't cause trouble to others. ”

Rob reached out and touched Luo Luo's hair, and said softly, "Okay, when your problems are solved, you can live wherever you want." ”

"Here we go again, how cunning. The girl sighed, "I'm afraid I'll get used to your gentleness if I go on like this." ”

"Isn't that bad?"

"Well, you must have done it on purpose so that I couldn't leave you. Lolo's eyes were like seaweed swaying underwater, making the boy's heartstrings tremble.

"Then don't leave me. ”

In the moonlight, the boy gently kissed the girl's forehead.

Bevinaveette stopped on a branch beside her, squinting at the two people under the tree, and at this moment it seemed as if only each other was left in their eyes, and the beautiful bird snorted softly, as if a little dissatisfied with being stuffed with dog food.

However, at this moment, a meteor suddenly crossed the sky, and the meteor dragged its long tail, piercing the night, and fell towards the northern grassland.

Then Rob raised his head, he also saw the meteor, and the future Super Magister raised his eyebrows, and seemed to be a little surprised, "Key!?"

"What key?"

"That meteor is a key, and it should be used to open some secret place on this level. Rob said, he felt a touch of familiarity from the key, and if he guessed correctly, it was probably the same person who made the key and the brooch treasure on his body.

At this moment when the two of them were talking, the earth suddenly shook, and those powerful demonic beasts entrenched in various places on the seventh layer became restless, and most of the demonic beasts at this level had a strong sense of consciousness, and they would not leave their territory easily, but when the meteor crossed, they all walked out of their respective nests for the first time and ran towards the place where the meteor fell, like a child who was in a hurry to grab candy, and Bevinaveette, who was still standing on the tree before, was also gone at this moment, and it did not hesitate to join this carnival。

Rob said to Lolo, "Let's go check it out, too." ”

The structure on the brooch treasure had helped him at several critical moments, whether it was the Lost Lock Circle by Lake Simers or the finger of the light giant, he could find a connection from that structure, which couldn't help but make Rob more and more curious about what kind of person was the guy who made this secret protection back then.
