The sword has been searching for its owner for centuries, and Nijin, Det, Yue and Yone set off together. Where they went, there was a severe winter and it was extremely cold. The temperature dropped to -1000 degrees and everywhere was covered with ice. Living things froze to death, and when they stepped on the ice-covered planet, they immediately began to freeze.
Nijin quickly draws an ice barrier around them and tries to protect themselves. Although he could normally cast an immunity spell against the ice element, he decides to make the legendary ice pills since they have a limited effect at -1000 degrees. The ingredients he needed were in his inventory and he quickly prepared these pills. The pills shine with blue and white sparkles. When the barrier is about to be completely broken, it takes effect immediately by distributing the pills to everyone. Nijin's system unlocks and he gains permanent ice resistance. The cold no longer harms them, they continue their progress.
The further they go, the more they realize that the cold gets worse. As they continue their journey, they encounter monsters and all the monsters are frozen in ice. They want to thaw a harmless monster and ask what it is. The monster begins to explain "What's going on here." He says that this place has been like this for centuries and that there is a secret entrance ahead. This is where the ice comes from, where all the monsters are covered in ice. Nijin and the others begin to move towards the mentioned place.
The monster they defrosted freezes again, and when they reach said place, they realize that it is much colder. There are thousands of ice monsters inside and their temperatures are much lower. Nijin, who is in a maze, quickly attacks the ice with his sword to destroy the maze, but the ice regenerates itself and protects the maze. They realize they have to find another way to get through the maze.
When they enter, a lot of ice monsters appear in front of them. Nijin quickly tries to defeat them, but they revive. Nijin comes up with an idea and adds the fire element to his sword. He attacks the ice monster and it begins to melt. A lot of monsters appear in front of them, but Nijin quickly defeats them and proceeds to the end of the maze.
When they finally reach the end of the labyrinth, there are 10 doors in front of them. Nijin creates copies of herself and sends them to the gates. But after a while, they realize that only one copy has survived. The surviving copy sends a message to the others, informing them that a giant door has not opened.
The Nijins go towards the door and there are writings on the wall in an ancient language. Det begins to translate these writings and reads: "Only the worthy can open this door." Nijin touches the door and the guardian of the door suddenly appears, coming from the shadows and trying to attack. However, Yone quickly intervenes and stops the guardian, while Det grabs the guardian's spear. Nijin forcibly removes the sword while trying to open the door, and the sword suddenly begins to glow. The tip of the sword takes the shape of a key and begins to rotate. Once the door is opened, the guardians disappear without a trace. They go in and it's empty, there are only two buttons. Det translates the writing on the wall and reads: "If you opened the door, if you're the right person, you'll know which button to press."
Nijin understands and presses two buttons at the same time. The landscape inside suddenly begins to change and a light emerges from the wall. A hologram of a person appears in the middle of the light and begins speaking. "If you came here, you know who I am. When you opened the door, you collected the keys lost in the universe and came here. You went through a difficult journey. Now there is another part that I did not tell you about. I divided the sword into four pieces and scattered three of them around the universe, but I kept the other piece here.
Divide the sword into three pieces and place them on the wall. "The fourth piece will appear," he says. Nijin divides the sword into three pieces and places them in the appropriate places on the wall. Then, an object begins to fall from above and the pieces on the wall begin to glow. They emerge from the wall and merge with the fourth glowing piece above. Finally, the sword turns into a devastating sword. The powerful sword appears and is now even stronger.
Nijin picks up the sword and the ice outside begins to melt. Everywhere begins to turn green, the trees grow and it returns to the way it was centuries ago. Nijin decides to try the sword. The wall of the maze was very strong, so he quickly ran and attacked the wall. The entire maze disappears and a person was waiting for them outside, this person is a time traveler.
