Yu Yue and his party were arranged to stay in the Wulan mage tower.

In the polar zone, the sun is below the horizon for half a year, and the night is up to 24 hours a day, which is called polar night.

The people of Wulan mage tower can't work at sunrise and rest at sunset. They can only listen to the tips of the magic clock in the tower to arrange their work and rest.

Although there is half a year of night, you can often enjoy the beautiful scenery of the aurora here.

The aurora is diverse, colorful, diverse and beautiful. No phenomenon in nature can match it.

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

The aurora sometimes appears for a very short time, just like the festival fireworks flash in the air and disappear without a trace;

Sometimes it can shine for hours in the sky;

Sometimes like a ribbon;

Sometimes it is like a fire, like a colorful huge screen, like a ball screen movie, giving people visual shock enjoyment.

In terms of accommodation, the supreme mage was not stingy. All the rooms arranged for Yu Yue and others were good rooms, which could see the ocean and the aurora.

Yu Yue and xiaograpefruit took a bath, took her to sit in front of the large French window and looked at the aurora, and told her that if we took a spaceship, crossed over the north and south poles of the earth, looked at the earth from the distant space, and saw a glittering light ring around the earth's magnetic pole, this ring is called aurora egg, because they are a little flattened towards the sun, The side away from the sun is slightly stretched, thus taking on the shape of an egg.

Little pomelo asked, "what is an egg?"

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

Xiaograpefruit clapped and laughed happily.

Of course, from the ground, the aurora has a variety of shapes.

Without exaggeration, as like as two peas in the world, two Aurora forms are almost impossible to find. From the perspective of scientific research, people divide Aurora into five types according to their morphological characteristics.

One is the arc-shaped Aurora arc with neat and slightly curved bottom edge;

Second, there are twisted and wrinkled streamer like aurora bands;

The third is the sheet-shaped Aurora like clouds;

The fourth is a tent like aurora curtain with uniform veil;

The fifth is the radial polar light along the direction of the magnetic line of force.

The brightness of Aurora forms also varies greatly, from the brightness of the Milky Way Nebula just visible to the brightness of the moon at the full moon.

When the strong aurora appears, the outline of objects on the ground can be seen, and even the shadow of objects can be seen, such as ships passing through Binglong Bay.

Of course, the most moving is the wonderful scene of rapid change caused by the aurora movement.

The movement and change of the aurora is a drama of light performed by the great magician of nature on the stage of the sky. It spans hundreds of kilometers up and down, and even has an aurora belt nearly 10000 kilometers long. It is magnificent. It takes the dark sky as a colorful drawing board and turns into a mysterious kaleidoscope.

Little grapefruit looked at the beautiful aurora and entered the sweet dream.

But some people can't sleep.

Like yekaterina, who realized her dream.

And her husband, Chen Wulong.

Originally, yekaterina's room was different from that of Yu Yue and others. She had moved into the magic apprentice dormitory.

Of course, as a disciple of the supreme mage, she doesn't live among four or six people.

She lives in a single room, and it's a deluxe single room.

Chen Wulong quietly touched Mimi and sighed when he entered the door: "your dormitory is good!"

The dormitory is luxuriously furnished, and the selection of decorations has the style of both magicians and great nobles. For example, a chair has a smooth satin back, and the soft leather wrapped on the armrest has some small scales, which are tight and tough, which seems to be the skin of some dragon.

However, neither Chen Wulong nor yekaterina noticed such details.

Chen Wulong only stared at the gorgeous big bed: "your bed is bigger than the one in my room. I don't know if it's more comfortable to sleep on it?"

Yekaterina asked, "what do you want to do?"

Chen Wulong has hugged her: "you... Guess..."
