Coach: Coaching the Grizzlies at the beginning, playing the bantam

"Lu Yong, is your sunscreen made of cement?" Hannah applied the white paste on her eyelashes. Lu Yong was holding the sunscreen spray to create a "sunscreen barrier" between the two of them.

Under the glass dome of the Ocean Park, the sound of artificial waves and the smell of sea salt hit me in the face. Xiaolin ran wildly on the spiral staircase carrying a waterproof camera: "You two! Look at the 'Mermaid Wishing Pool' at the entrance. Throwing a coin can summon dolphins!"

Hannah suddenly grabbed the corner of Lu Yong's clothes and pointed at the half-broken postcard sticking out of the side pocket of his canvas bag: "Isn't this a letter from Xibaipo to the future? Why is it here?"

Lu Yong scratched his head and grinned: "I sent a 'time-space express' to the aquarium last night - I heard that their underwater tunnel has a 'future messenger' service, which can put letters in a drift bottle and throw them into the artificial sea."

Before he could finish his words, a child's scream suddenly came from the front.

I saw a boy in a dinosaur jumpsuit lying on the glass of the penguin house, his snot condensing into ice crystals in the minus five-degree cold air: "Mom! The penguins are square dancing!" He stomped his feet, making the ice surface tremble slightly, and the dinosaur tail in his arms swept down the "Please do not hit the glass" sign placed by the staff.

Hannah squatted down to look at the boy, and took out a bag of panda biscuits from her canvas bag: "Little warrior, do you want to play the 'biscuit catching on ice' game with the penguins?" She broke the biscuits into pieces and scattered them in front of the observation window. The chinstrap penguins, who had been drooping their heads just now, suddenly straightened their necks and swayed towards them like a group of little gentlemen in tuxedos.

Lu Yong took out his phone and played "The Blue Danube". The penguins glided in a line to the melody, and the ice chips splashed under their feet like stars. The boy was stunned and his dinosaur tail drooped unconsciously. Hannah handed him the last cookie and said, "I'll tell you secretly, penguins hate noise the most - when they are dancing waltz, you have to be a quiet audience."

Xiao Lin took a sneak shot behind the decorative icicles. In the camera, Hannah's floral dress contrasted with the penguin's black and white wings. Lu Yong's finger holding the phone cast a slender shadow on the glass. One photo was frozen in the moment when the boy held his breath and concentrated - the ice crystals on the tip of his nose reflected the elegant curve of the penguin, and the dinosaur's tail looked like a shy mimosa.

When the three of them stepped into the underwater tunnel, Hannah suddenly grabbed Lu Yong's wrist. Schools of sardines were passing overhead, and among the silver waves, a mimic octopus suddenly stretched out its tentacles, casting a heart-shaped spot of light on the glass. "Lu Yong, look! It's writing a love letter!" Hannah stood on tiptoe to reach the flowing light and shadow, and the tip of her hair brushed Lu Yong's chin.

Lu Yong took out two fluorescent bracelets from his canvas bag. The blue halo turned into a galaxy in the dark blue water. "This is the 'deep sea love transmitter' specially provided by the aquarium. Turning the bracelet can project what you want to say." He turned his wrist first, and a line of small glowing words suddenly lit up on the wall of the tunnel: "Hannah, today's penguins are cuter than pandas - because they are learning to dance like you."

Hannah blushed and grabbed the bracelet, but when she turned it, the gear got stuck.

Countless spots of light exploded above her head, forming a sentence: "Lu Yong's sunscreen smells like dried bamboo leaves, but I like it." She hurriedly tried to cover the spots of light, but saw that the tips of Lu Yong's ears were as red as coral reefs. Behind her came the sound of Xiao Lin coughing, which was caused by trying to hold back his laughter.

When passing through the rotating jellyfish light box area, Hannah's skirt was suddenly entangled by the jellyfish model. The transparent tentacles rippled on her calves. She was about to bend down to untie them, but Lu Yong had already knelt on one knee and gently pushed aside the simulated tentacles with his fingertips: "Be careful, don't let the 'Moon Jellyfish' steal your heartbeat." When he looked up, Hannah found that his eyelashes were stained with the fluorescent powder of the jellyfish light box, like a layer of fine snow.

"Look here, guys!" Xiao Lin suddenly poked his head out from behind the cylindrical jellyfish tank, and the slow-motion shooting interface lit up on his phone screen. The moment just now was frozen into an oil painting - Lu Yong's half-kneeling silhouette intertwined with the fluorescent tentacles of the jellyfish, and Hannah's posture of holding up her skirt was like a princess in a fairy tale.

He pressed the send button: "I just sent this picture to the official Weibo of the aquarium. The title is "The Real Mermaid Princess and Her Research Knight"."

Hannah was about to chase Xiaolin when she suddenly caught sight of an old couple sitting next to the jellyfish tank.

The old lady was trembling as she was throwing fish food into the water, while the old man was holding up his Polaroid camera but couldn't get it to focus properly: "Old woman, tilt your head a little more... You were so smart when you were chasing me, but now you look like a sloth when you take a photo!"

Lu Yong quietly took out a portable tripod from his backpack, adjusted the parameters, and handed the phone to Hannah: "Let me take a photo of you two 'across time and space'."

He guided the old couple to pose in the classic pose of their youth - the old lady grabbed the old man's ear and the old man pretended to beg for mercy. At the moment when the Polaroid camera spit out the photo, Hannah found Lu Yong making a "V" sign in the corner.

When the dolphin show started, Hannah was pushed to the center of the audience.

When the white whale jumped out of the water and pushed up the red ball, Lu Yong suddenly stood up and took out a shell-shaped whistle from his trouser pocket.

The clear whistle pierced the cheers in the theater, and three dolphins turned towards him in unison, drawing three silver parabolas in the water.

"This is the 'Dolphin Code' taught by the XSQD fishermen." Lu Yong stuffed the whistle into Hannah's palm, "Blow it, and the dolphins will convey the secret signal for you." Hannah blew the whistle half-doubtfully, and the nearest dolphin suddenly jumped out of the water and touched her raised right hand with its snout - a shell necklace was hanging on the tip of its nose.

As the audience exclaimed, Xiao Lin controlled the drone to push the camera toward the inside of the shell. Under the ultraviolet light, fluorescent words appeared on the inner wall of the shell: "Hannah, do you want to unlock the '20,000 Leagues Under the Sea' achievement with me? - Lu Yong."

Hannah turned to look at Lu Yong, only to see that he was being taken a photo with the old couple.

The old lady held up the Polaroid camera and forced Lu Yong to sit next to the old man. "Young man, you can take photos and understand dolphins. You are much better than my wooden grandson!"

The old man secretly stuffed a piece of fruit candy into Lu Yong's pocket. The wrapping paper was still the "White Rabbit" style from 20 years ago.

When the three of them came to the artificial coral cultivation area, Hannah suddenly squatted in front of a heart-shaped coral and did not move.

Lu Yong took a closer look and found a rusty drifting bottle stuck between the coral branches, with a faded red ribbon tied around the bottle stopper. "This is the 'time capsule' that was put in when the aquarium opened in 2003!" the administrator explained with a loud speaker, "It takes a couple to work together to turn the turntable on the coral to open it!"

As soon as Hannah's hand touched the turntable, Lu Yong had already grasped the other side tacitly.

The coral tentacles felt slightly hot in their palms, the turntable stirred up fine golden sand as it spun, and the drifting bottle popped open with a "click".

There were two stick figures drawn on the yellowed letter paper. The girl was holding a balloon and the boy was holding a starfish. Below, childish handwriting read: "When we grow up, we will take the penguins to the North Pole to see the aurora!"

"This is..." Hannah's voice trembled, and Lu Yong had already taken out a new drift bottle from his canvas bag.

He stuffed in a Polaroid camera - in the photo, Hannah was holding a shell necklace and smiling, and there was still fluorescent powder on Lu Yong's ears - and then put in a copy of Xibaipo's "Letter from the Future", and finally wrapped the bottle mouth tightly with waterproof tape.

"This time it's our turn to bury the time capsule." Lu Yong stuffed the bottle into the crevice of the coral. Amid the sound of the waves, Hannah could hear her own violent heartbeat.

She suddenly turned around and rushed towards Lu Yong, her hair brushing across his collar stained with sea salt: "Fifty years later, we will bring the grandchildren of penguins and dolphins to dig!" The moment she stepped into the Polar Museum, Hannah sneezed.

In the freezing cold of minus 20 degrees, the Arctic fox was curled up in the artificial snow and taking a nap, and the snow wolf was walking gracefully behind the glass, like a supermodel on the catwalk. Xiaolin suddenly raised the thermos cup: "Would you like a sip of vodka to warm yourself up? Specially provided by the Russian curator!"

"Where did you get it from..." Hannah just took a sip and stuck out her tongue because of the spiciness, but Lu Yong snatched the cup and drank it all in one gulp, his ears instantly turning red: "Good wine! It's very similar to the Zhuyeqing we drank in Xibaipo."

"Lu Yong, are you crazy? This is 58-proof vodka!" Hannah reached out to grab the thermos, but her fingertips touched his hot earlobe.

Lu Yong staggered and bumped into the glass curtain wall. The Arctic wolf behind him suddenly stood up, and its front paws slapped the ice with a dull sound.

Hannah hurriedly tried to help him, but he took advantage of the situation and encircled her in the artificial snow mist. The white breath he exhaled entangled the ends of her hair. "Now I am an explorer drunk in the snowfield, and you are the goddess of the aurora who came to save me."

Xiao Lin emerged from his penguin costume, holding up his GoPro and filming frantically: "This segment must be accompanied by the Frozen background music! The title should be "A Chinese Researcher and His Arctic Princess!" Before he finished speaking, Lu Yong suddenly ripped off Hannah's red hairband and waved it like a burning flag in the sub-zero temperature: "Look! Even more blazing than the aurora—"

Hannah blushed as she tried to grab the headband, but saw that Lu Yong had already tied it next to the Arctic fox's snow den. The little guy was awakened, shook off his silver fur, tilted his head and yawned in front of the camera. Hannah suddenly stood on tiptoe and grabbed Lu Yong's collar, and kissed his red nose: "This is the 'Polar Survival Certification', now you are my legal expedition partner."

When the snow wolf exhibition area lit up with a dim blue night light, Hannah was lying on the glass and imitating a wolf howl.

Lu Yong suddenly covered her eyes from behind: "Don't make a sound, it's choosing its prey for tonight." With the residual warmth of vodka in her warm palm, Hannah's eyelashes brushed across the callus on his knuckles: "Who did it choose? The drunk who secretly drank strong liquor, or the...female gangster who secretly kissed the drunk?"

Lu Yong's palm trembled violently, but he saw that the Snow Wolf had turned around gracefully, its golden eyes flashing like amber in the darkness.

It suddenly tapped the ice with its front paws and let out three short calls - exactly the same as Hannah's wolf howl. "It's responding to you." Lu Yong let go of his hand, his Adam's apple rolling in the dim light, "Legend has it that the snow wolf will only show its fangs to the destined person, or..."

He suddenly knelt on one knee and took out an ice crystal pendant from his canvas bag.

Under the cold light, the pendant contains a piece of bamboo leaf from Xibaipo and fluorescent sand from the aquarium: "Or... give the most precious treasure to someone who can understand its song."

Hannah's tears hit the ice, and tiny ice flowers bloomed instantly. She put on the pendant tremblingly, and heard the long whimper of the snow wolf in the distance, like blessing, but also like urging.

"Ms. Hannah, are you willing to marry Mr. Lu Yong as a 'glacier couple'?" Xiao Lin, wearing a penguin doll costume, presided over the sudden "polar wedding" with a funny mechanical voice. Twenty Papua penguins lined up on both sides of the "auditorium", and the ice sculpture arch above their heads was decorated with LED stars.

Lu Yong poured two glasses of "special champagne" from his thermos cup - actually apple juice mixed with Sprite, the bubbles condensed into pearls in the sub-zero temperature. He was about to hand it to Hannah, but a greedy Adélie penguin knocked the glass over. The juice curved into a heart shape on the ice surface, and the penguins happily tapped and stepped on the ice surface to create galaxy-like cracks.

"Please exchange the 'Glacier Tokens' now!" Xiaolin used the doll's wings as a tray and presented two Arctic clam fossils.

Lu Yong put the one with Xibaipo's longitude and latitude on Hannah's neck, and she put the shell with the oceanarium's coordinates into his pocket. Suddenly, the flashlights of tourists' mobile phones flashed across the entire glass curtain wall - strangers holding cameras had gathered at the Polar Museum before, as if they were witnessing a real polar wedding.

When the melody of "My Heart Will Go On" came from the underwater tunnel, Hannah was curled up in Lu Yong's coat to keep warm.

The lights in the White Whale Theater gradually dimmed, and a spotlight hit the white whale that jumped out of the water. It held a glowing jellyfish light in its mouth, drawing a graceful arc in the night sky.

"This is the 'Moonlight Love Song' performance at the aquarium." Lu Yong suddenly leaned close to her ear and said, "But it is said that beluga whales only sing for those they truly love."

Before he finished speaking, the white whale suddenly let out a long cry, and the sound waves spread out ripples under the dome. Hannah felt something cold being stuffed into her palm - it was the shell whistle, which was now slightly warming in Lu Yong's palm.

She plucked up the courage to blow the whistle, and the white whale swam towards them, nudging their clasped hands with its snout.

When its eyes reflected the two people's reflections under the searchlight, Lu Yong suddenly said: "Hannah, listen - it is singing the 1948 telegraph code and also the satellite waves. From the bamboo sea in Xibaipo to the ocean here, all the signals are saying..."

Hannah stood on tiptoe and kissed his trembling lips. The white whale made a cheerful "click" sound, and the sound waves exploded on the glass curtain wall into a starry sky. Xiaolin hid in the control room and took a sneak shot. The shadows of the two people in the camera overlapped with the silhouette of the white whale to form an eternal sculpture.

Before the museum closed at midnight, three people accidentally entered the unopened ice sculpture maze.

Hannah's red hairband fluttered like fire among the ice edges. In the beam of Lu Yong's mobile phone flashlight, the ice crystals reflected millions of their figures.

"Look at this!" Xiao Lin suddenly opened a wall of ice and found a message from a tourist 1998.7.15 years ago. In faded marker pen, it said: "Zhang Jian & Li Xiulan visited here on July , . May their lives be like ice sculptures that never melt."

Hannah took out a highlighter from her canvas bag and wrote on the adjacent ice: "Lu Yong & Hannah passed by, promising to make love last longer than the glaciers."

As soon as she finished writing, Lu Yong had already used a dagger to carve miniature longitude and latitude on the bottom of the ice - these were the coordinates connecting Xibaipo and the Oceanarium.

Suddenly, a mechanical female voice rang out throughout the maze: "'Time and Space Love Letter' detected, and the 'Eternal Freeze' program is about to be activated." The ice wall began to slowly close, and Xiaolin screamed and ran away: "Help! Are you really going to turn us into ice sculptures?!"

Lu Yong suddenly laughed and ran towards the exit with Hannah in his hand: "This is the hidden Easter egg of the aquarium! When the aquarium opens tomorrow, our love letter will become a new attraction!"

He turned back and blinked at the camera, "Remember to add a subtitle to the documentary: 'This program is sponsored by Love That Never Fails to Fear'!" (End of this chapter)
