In her sophomore year of high school, Xia Ancheng transferred to Sheungshui No. 1 Middle School.
She habitually went to the K area of the library to look for "Rare Vortexes in the World", where she met Chi Muzhen who was reaching for the book at the same time.
"Classmate, do you also like vortexes?"
Xia Ancheng nodded and walked to the bookshelf to sit down. Just as he was confused by a blurry satellite image, Chi Muxin's voice came from the other side.
"This picture records a rare vortex that appears in the polar regions - the winter vortex, but it only appears in late winter and is as short-lived as the rise and fall of the tide."
Xia Ancheng stared at this vague abyss. It was like a wandering ghost, unfathomable.
"I want to see it with my own eyes."
"What a coincidence, so am I."
From then on, they always spent time in the library together, chatting and thinking about the future. Chi Mujin even predicted the possible places.
"I must become a marine surveyor." Xia Ancheng said firmly.
"I want to study medicine..." Chi Mujin paused.
"You go surveying, I'll wait for you to come back."
Later, Xia Ancheng became a marine surveyor as he wished and established his own laboratory.
Regardless of everyone's doubtful eyes, I persisted year after year with faith.
It wasn't until late winter of the third year that something abnormal appeared on the screen under the polar night. Xia Ancheng found the satellite image and put it on the screen for comparison.
Yes, that's it, Winter Vortex.
Xia Ancheng stood up and walked to the deck, writing "Coordinates (68°N, 5°E)" next to the satellite image.
"Chi Mujin, I found it."
