The two boys nodded suspiciously and looked expectantly at the stone wall that was about to open up to reveal the upper floors.

The door slowly began to open, marveling at the two children, as they ran towards the exit and touched the wooden shelves.

—It was true! It's all made of wood!—Apollo shouted excitedly as he touched the neighboring shelves, causing some heads to come out to greet him.

—Yes, look, the books seem to be written in another language—Hermes said, taking one of the books from a shelf and putting it down. The head of the bookshelf from which Hermes took the book stared at the boy suspiciously, seeming hesitant to ask him to do the riddles.

—What are you brats doing? They're going to kill you!—Adam shouted angrily, running to return the books to the shelves and grabbing the boys behind their robes, so they wouldn't escape—Listen carefully, don't touch any bookshelf and don't listen to them. Don't do anything weird and just follow me.

The two boys with some fear nodded, they seemed to be looking to free themselves from Adam's grip, so they could run away.

—They're going to be fine, they're from kindergarten—someone answered with a rather cheerful voice.

Adam turned around and looked at the source of the voice, it was the monk who had come out to see the fuss they had made.

—What's daycare?—Adam asked as he checked to make sure the kids didn't run off again.

—Study it, I shouldn't answer your questions—answered the monk, looking at Adam sadly—but the gray robes are from the nursery, and we can't give our books to the children who live there. So don't worry so much, no one will do anything to them.

Adam looked at the boys' robes, because of the lighting in the cave and having his mind elsewhere, the young man didn't notice the problem with the color of the boys' robes, but now he realized that they could draw attention. But they also had the IDs, so they should be fine.

—What's the nursery?—Adam asked, looking at the two boys whose robes he was holding, so they wouldn't run away.

—Where we live, will you let us go?—Hermes asked with some annoyance.

—Yes, but don't run away—Adam replied in a tired voice—The librarians in this area are more dangerous than the bookshelves these days, so if you run too far they might kill you, like the lunatics on the lower floors.

—Seriously?—Apolo asked fearfully, looking suspiciously at the corridors—Where are the mannequins? We are alone here: It is dangerous!

—Pretty dangerous!—Adam added—Besides, the old man with sharp teeth from the cave put a bomb on their heads. If they get too far away from me, their heads will explode, and they'll turn into books.

—Hey? But why?—Hermes said, crying as he touched his head to try to feel something abnormal.

—Don't think about it too much, we're just going to complete the mission and come back—Adam answered with a tired voice, while he let go of the boys and started walking forward. But now he realized that there was another problem and that was that he couldn't walk because he had the two scared boys stuck in his legs preventing him from advancing.
