Yu Yue and his party were arranged to live in the Ulan Mage Tower.

In the polar circle area, the sun is below the horizon for half a year, and the night is 24 hours in a day, which is the extreme night.

The people in the Ulan Mage Tower cannot rest at sunrise and sunset, so they can only listen to the magic clock in the tower to arrange their work and rest.

Although it has been a dark night for half a year, you can often enjoy the beautiful scenery of aurora here.

Aurora is diverse, colorful, with different shapes and extremely beautiful. There is no phenomenon in nature that can match it.

It is difficult for any colored pen to draw the dazzling light that is playing in the extremely cold and unpredictable air.

Aurora sometimes appears for a very short time, just like the fireworks of festivals flashing in the air and disappearing without a trace;

Sometimes it can shine in the sky for several hours;

Sometimes it's like a ribbon;

Sometimes it is like a ball of fire, like a huge screen with colorful colors, as if a ball screen movie was released, giving people a visually shocking enjoyment.

In terms of accommodation, the Supreme Master was not stingy. He arranged good rooms for Yu Yue and others, and could see the ocean and aurora.

Yu Yue and Xiao Youyou took a shower, took her to sit in front of the big floor-to-ceiling window and watched the aurora, and told her that if we take a spaceship, cross the north and south poles of the earth, and look towards the earth from distant space, we will see a shiny halo around the earth's magnetic poles. This ring is called aurora egg, because one side of them is slightly flattened toward the sun, while the side of the back of the sun is slightly stretched, thus taking the shape of an egg.

Xiaoyouyou asked: "What is egg?"

Yu Yue said: "It's just an egg. From space, the extreme light is like a big baby egg."

Xiaoyouyou clapped her hands and laughed happily haha.

Of course, from the ground, the aurora has various shapes.

It is no exaggeration to say that there are no two identical aurora shapes in the world. From the perspective of scientific research, people divide aurora into five types according to their morphological characteristics:

One is an arc-shaped aurora arc with neatly curved bottom edges;

The second is a ribbon-shaped aurora belt with curved twists and wrinkles;

The third is a cloud-like aurora;

Fourth, aurora curtain like a uniform veil;

Fifth, the ray-shaped aurora rays along the direction of the magnetic force line.

The brightness of the aurora shape also varies greatly, from the brightness of the Milky Way that can be seen just now, until the brightness of the moon at the full moon.

When strong aurora appear, the outlines of objects on the ground can be illuminated, and even the shadows of objects will be reflected, such as ships coming and going on the Ice Dragon Bay.

The most moving thing is of course the ever-changing and wonderful scene caused by the aurora movement.

The movement and changes of the aurora are a drama of light played by this great magician in nature, using the sky as the stage. It is hundreds of kilometers long, and there is even a belt of nearly ten thousand kilometers long. It is magnificent and magnificent. It uses the dark sky as a colorful painting board and becomes a mysterious kaleidoscope.

Xiaoyouyou just looked at the beautiful aurora and entered a sweet dream.

But some people can't sleep.

For example, Ekaterina who realized her dream.

And her husband, Chen Wulong.

Originally, Yekaterina's room was not together with Yu Yue and others' rooms, so she had already moved into the magic apprentice dormitory.

Of course, as the personal disciple of the Supreme Master, she did not live in the four-person or six-person.

She lives in a single room, and a luxurious single room.

Chen Wulong quietly touched him and sighed as he entered the door: "Your dormitory is good!"

The dormitory is luxuriously furnished, and the decorations are both the styles of magicians and great nobles. For example, a chair has smooth satin back and the soft leather wrapped on the armrests has some subtle scales, which are tight and tough, and seem to be the skin of some kind of dragon creature.

However, neither Chen Wulong nor Ye Katerina noticed such details.

Chen Wulong only stared at the gorgeous big bed: "Your bed is bigger than the one in my room. I wonder if it is more comfortable to sleep on it?"

Yekaterina asked: "What do you want to do?"

Chen Wulong had already hugged her: "You... guess..."
