On the sixty-ninth day of entering the dungeon, Rob and Lolo finally arrived at the seventh floor.

There are powerful monsters, terrifying mechanisms and metal puppets living here. Even with Bevinadette leading the way, the speed of the two of them still slowed down.

Even Rob had to act carefully here. The future Super Magician released his mental power and sensed the hidden dangers around him. Lolo also took out the small bottle of red raw glue from his luggage. This thing was given to her by an ugly woman during Ogrind. Applying it on her body can effectively isolate her own breath, and it is difficult for even a ninth-level professional to find out.

On the sixth floor, the girl tried it. Although she didn't know how the metal puppets searched for the invaders, the good news was that the red raw rubber was indeed effective for them. As long as the two of them applied this thing, they would turn a blind eye to them even if they passed by the metal puppets. Although the metal puppets on the higher level were more powerful, the mechanism for recruiting enemies did not change. Therefore, it is time for the red raw rubber to be used.

On the second and third floors, Lolo and Rob can also find footprints of a few adventurers' activities, but after entering the fourth floor, you will never see other adventurers again, and it seems that 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, and the ecosystem inside is still well maintained. The man-made sun, moon and stars change tirelessly in the air, and even if it is more than 2,000 meters underground, it can still breathe fresh air.

Things in the outside world can be found here, whether it is mountains, rivers, hills or lakes... it seems that the people who created this world want to copy everything on the ground.

The more I saw, the deeper the doubts of Lolo were. Since the creators of the dungeon liked the surface so much, why did they build such a place in this deep underground? Who are those towering mitral walls resisting?

As if seeing what she was thinking, Rob explained, "This is the place of the beginning."

"Um?"

"This dungeon is the first dungeon in the world. The dungeons in other places were built after it."

"How did you know?" the girl said curiously

"I once followed the teacher to explore a dungeon. The dungeon was perfect, both in structure and in structure, but compared with this, the most important thing is missing."

"What?"

"Traces of failure." Rob continued, "This dungeon was not built in one go. I discovered this when I first came to see the sewage pipes in the inner city. Those pipes have many traces of changes. The designers made many attempts, some succeeded and some failed. They retained the part of the success and continued to improve on this basis... In fact, it is not just those sewage pipes. Everything you see here has the mark of failure. The stars and rivers, the sun and the valleys, and every inch of land are the products that have been bred after countless failures."

"They?" Lolo grabbed the point of the sentence, "You mean there is more than one person who designed and built this dungeon?"

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

"According to your words, that civilization was once extremely powerful, why did they decline?"

"We are back here this time to find the answer to this question." The future Super Magician replied.

“Is this answer important to us?”

"It's very important. If my guess is confirmed to be correct, they should have a solution to your problem." Robu said, but there was another sentence he didn't say. If his guess is correct, then humanity is now facing the biggest crisis ever.

Lolo said, but her focus was not on this. After a pause, the girl said, "Hey, these days, I occasionally think... It might be good for us to live here. Isn't it take hundreds of years to guide a dungeon? We only need to live on a few floors on a high place, so that no one will disturb us. We can spend the rest of our lives quietly and will not cause trouble for others."

Rob reached out and touched Lolo's hair, and said softly, "Okay, when the problem is solved, you can live wherever you want."

"It's coming again, so cunning." The girl sighed, "If this continues, I'm afraid I will be unable to help getting used to your tenderness more and more."

“Isn’t this good?”

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

"Then don't leave me."

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

Bevinadette stopped on the branch beside him and looked at the two people under the tree. At this moment, they seemed to be left with each other in their eyes. The beautiful bird snorted, as if he was a little dissatisfied with a mouthful of dog food stuffed into it.

However, at this moment, a meteor suddenly passed by in the sky. The meteor dragged its long tail, cut through the night and fell towards the grassland in the north. Bevinadette's expression suddenly changed after seeing the meteor.

Then Rob raised his head and saw the meteor. The future Super Magician raised his eyebrows, as if he was a little surprised, "Key!?"

“What key?”

"That meteor is a key, which should be used to open a secret place on this floor." Robu said, and he felt a familiar breath from that key. If he guessed correctly, the person who made the key and the brooch treasure on him might be the same person.

Just as the two of them were talking, the earth suddenly vibrated, and the powerful monsters entrenched in various parts of the seventh floor became restless. At this level, the consciousness of the monster realm was very strong and would not leave their territory easily. However, when the meteor passed by, they all walked out of their nests for the first time and ran towards the place where the meteor fell, like a child who was rushing to grab candy. Bevinadette, who had been standing on the tree before, was nowhere to be seen at this moment, and it joined the carnival without hesitation.

Rob said to Lolo, "Let's go and have a look, too."
