The next day, Kai went to Class 1, where he studied magic for two hours and practiced magic for another two hours. After school, he decided to visit the pyramid for the first time. Kai took a quest from the Adventurers' Guild, which was: "Kill 5 E-rank monsters or 2 C-rank monsters."
When Kai entered the pyramid for the first time, he encountered Lilith, a B-rank, at the pyramid's entrance, waiting for her team known as "Black Command." This team was renowned for its strength and achievements in the pyramid, having reached Floor 13, becoming the first team to do so. Lilith called out to Kai, but he ignored her as if he didn't recognize her.
Kai proceeded to Floor 1 and encountered his first monster, a C-rank wild wolf. After killing 2, he completed his quest and returned to the guild, handed over the wolf's bones to the guild worker, and received his reward. Kai then went back to his lodgings, had dinner, and went to bed. The next day, he returned to the pyramid, this time without any quest, just to explore.
Kai reached Floor 5 and began encountering B-rank monsters until he faced an A-rank golem. Kai defeated it in the blink of an eye and stored its remains in his pouch. When Kai reached Floor 13, the floor no human had ever surpassed, he saw human skeletons and numerous corpses, with no monsters around, as if there was a surprise waiting on the next floor.
The first boss floor...
When Kai arrived at Floor 14, he felt an immense magical energy he had never felt before. It was the magic of the first boss in the pyramid, known as *The Black Slayer*. This boss was classified as S-rank, or the first elite tier.
Kai entered the boss room and saw the boss. The Black Slayer, the boss of Floor 14, was an S-rank with a black scythe that seemed like a cursed weapon that kills anyone who touches it. The Black Slayer cast a strange spell that Kai had never seen before; it looked like invisible black snow, but thanks to his dragon eyes, he could see it.
Kai countered the attack with a Level 60 spell, "Billion Arrows," which defeated the boss effortlessly, as if he were facing a novice. However, that was just the beginning...
The boss did not die but used a Level 80 defensive spell and transformed into a strange form, becoming an SS-rank, the second elite tier. The boss attacked Kai with a speed he had never seen before, and Kai thought it was the end as the Black Slayer struck him with his sword, throwing him against the far wall of the massive room.
Kai was hurt for the first time since entering the royal city. The Black Slayer approached Kai with an intent that sent shivers down his spine—an intent to kill. The Black Slayer swung his scythe at Kai, but Kai used, for the first time, the Dragon Eye skill, the deadly Dragon Eye skill, which easily defeated the Black Slayer.
Kai proceeded to Floor 20, not knowing it was the last floor of the pyramid, where he would confront the truth of the pyramid...
On Floor 20, Kai found a gate and entered, only to be surprised by a dragon. A legendary blue dragon with eyes like glowing blue crystals, large wings covering the entire room, and scales that seemed like diamonds. It was the legendary blue dragon, one of the four legends. The surprise came when the dragon looked into Kai's eyes, raised its wings as if to attack and destroy Kai, leaving Kai paralyzed and unable to move.
The dragon spoke, and Kai was astonished to hear it talk.
Dragon: "You, who have inherited my power."
Kai: "Me?!"
Dragon: "Yes, you. You are the bearer of the code. You are the one who can face the World King who seeks to destroy all worlds. You will unite with the heirs of the legendary powers. Your code is: Blue Dragon Attacker."
Kai: "What?! The blue dragon attacker code? What should I do with this code?"
Dragon: "The code is the symbol of our world and the source of your power from me, the blue dragon."
Kai: "And who are the heirs of the legendary powers?"
Dragon: "There is information I cannot reveal to you, Kai. You are the heir of the blue dragon power, the ruler of the Eastern World. Embrace the responsibility of this power."
Dragon: "It is time. I will be at your command, Blue Dragon bearer. Let us protect this world."
