Ke Xue: I picked up a bottle of sherry at the beginning.

"Oh... so dreamy... the big tank at night is like the universe..." Cheng Shi couldn't help but laugh out loud. It was her first time to go out on a date with a man.

"It seems that I chose the right date place." Bai Quanyi said.

"Are we dating?"

"What do you say?"

"It feels so amazing."

in the crowd.

"I'll be your guide today. I'm Sakai, a staff member at Hanayo Aquarium. When you hear the phrase 'nighttime aquarium tour,' what comes to mind?"

The guide, Ms. Sakai, asked Shiraizumi Masu, who was standing at the front of the group of couples.

Shiraizumi said, "Um... I was thinking of visiting the aquarium at night... Recently, cyan LED lights have become popular for nighttime aquarium activities. The blue light is very suitable for the aquarium at night."

"He seems like a handsome guy who knows a lot about the latest things in the aquarium. Your girlfriend is so beautiful. Are you looking forward to tonight's 'couples only' event?"

"Is it because you're staying overnight? But you're just going to sleep on the floor and watch the sink, right?"

"No, no, no. Think about it... this tour is a 'nighttime' tour~"

"Oh……"

"Speaking of nighttime... For example, take the nighttime snack eel pie. It's delicious and nutritious, but it's not recommended for children, right? It's the same reason."

What was she saying... Cheng Shi tilted his head.

"So, the main course for everyone tonight is the fishes' love life at night. Hehehe..."

After hearing Ms. Sakai's declaration with a smile on her face.

Noise…noise….

So "night" has this meaning...? The couples started to make a noise.

"Watching fish go about their adult lives at night? That's an activity only for adults?"

Bai Quanyi thinks that this kind of activity is more suitable for popularizing science to children.

"Well, let's go and watch the fish's nighttime love life. Fish reproduce through external fertilization, so they don't mate. Their breeding activities are truly beautiful."

Ms. Sakai was very excited for some reason.

"I prefer night aquariums to day aquariums. This is because most fish reproduce at night, just like the human couples here today."

Bai Quanyi couldn't help but complain: "Watching the fish breeding at night is really exciting, but it's really something that children can't watch."

Asai Narimi chuckled and said, "I think it's quite interesting."

Led by Ms. Sakai, everyone once again began to visit the medium-sized water tank with a southern style.

"Among fish, some practice monogamy like us, while others follow the law of the jungle, with strong males creating harems. Those male fish that create harems to reproduce are truly terrible!"

....... ......... 0

Asai Narimi chuckled and said, "Bai-kun, you are the powerful male fish."

Bai Quanyi said embarrassedly: "Actually, I am the owner of the fish pond."

The tour guide enthusiastically explained, "Any male living thing in the world will constantly pursue beautiful women. Otherwise, life wouldn't be able to evolve. Okay, please look at this tank. It's filled with night wrasses. Ah, they're quite energetic... The male and female sync their breathing to lay eggs—"

A female fish whooshed vertically to the top of the tank.

The male fish began to swarm after the female fish.

then.

"Look! The spawning has begun! Then comes the massive release of sperm from the males. Ahhh... the love life of fish. It's so beautiful no matter how many times I see it."

The water in the sink looked a little murky. Could it be because... the couples started whispering to each other.

"Every night they release eggs and sperm all over the tank like this. Many fish don't get excited until sunset, so you can only see this at night. Ah, here they go again! What do you think? Look, they're coming!"

"If the male and female don't coordinate, it's hard to succeed. This is the same as for all of you humans!" Ms. Sakai explained excitedly, perhaps a little too excitedly.

"Tropical fish deserve special mention here; they reproduce every night. If we were to compare them to humans, they'd be like those in Latin America. Warm weather makes us horny. Ah, this time it's a couple of butterfly fish!"

Bai Quanyi curled his lips. This young female tour guide is really dedicated.

241. Reproduction activities

I thought it would be a more romantic date, but the focus of Ms. Sakai's introduction became more and more off-topic...

"Um... Ms. Sakai? It's a rare opportunity to visit an aquarium at night. Besides the breeding activities, are there any other activities..."

"I know, I know! Everyone, please look at the tank over there. Those fish with red and white stripes are the clownfish that everyone is familiar with."

Clownfish are famous tropical fish that live by hiding in sea anemones.

"Clownfish are a super-athletic species. And! Only the strongest in the group becomes 'female.' The losing clownfish become male...it's totally feminist."

"Ehhhhhh?" Masami Miura let out a cute scream.

"Chengshi, if you were a clownfish, you would definitely be the strongest one." Baiquanyi said with a smile.

Ms. Sakai continued her explanation of gender transformation.

"Many fish species undergo sex change! For example, the cleaverfish here, like the "790," originally consisted of only females. The strongest individuals in the group then become males. And the transformation lasts only an hour. The masculine leader can possess all the females in his group, like a harem!"

"If you put all females in a tank, the strongest individuals will become males. There are many fish that follow this pattern. Conversely, if you put a lot of males in a tank, the males will become females. Fish like this adjust their sex ratio to their environment. This happens in the human world too! For example, in prisons..."

Ms. Sakai explained with a bright smile, and Shiraizumi was amazed. "...In American prisons, women often play the role of the weakest prisoner...Is that what you mean?"

After a gender reassignment lesson, everyone went to the shark tank.

"Look! The shark is riding on its companion's back and biting it with its sharp teeth!"

"At first glance, it looks like a fight between male sharks... but it's actually a male and female shark mating!"

"Oh, because sharks are special! Look, look. To prevent the female from escaping, the male bites her like this. It's really wild. Hehehehe, and then he takes advantage of the female's inability to resist!"

"Bai Jun, I think yours is more powerful than a shark!"

Asai Narumi has personally experienced Hakuizumi Masu's human weapon, which is even more powerful than the Super Power Blue Cat Invincible Cannon!

"I'm not as rude as a shark."

This was actually the first time that Bai Quanyi had seen a shark. It was really too fierce... too rough...!

"Shiraizumi Mashi...are you trying to hint at me in a roundabout way...trying to tell me 'it's almost time for me to eat you'?"

"I'm full, but I won't refuse dessert after dinner."

Ms. Sakai leaned over and whispered to Asai Narimi, "Miss, are you already impatient to have sex with your boyfriend?"

Asai Narimi said: "No, besides, she just this afternoon..."

Ms. Sakai glanced at the powerful and handsome Shiraizumi Masushi and said, "Wow! I'm so envious!"

So, the final event arrived.

"The aquarium's night lights aren't LEDs. After the breeding season, as everyone knows, it's Sage Time. So... what you'll see next are the marine creatures radiating a romantic glow..."

Walking along the pitch-black circular route, Ms. Sakai said, "This is a wonder you can never see during the day," and called everyone to admire the "luminous biozone" that she was proud of.

"Why are there so many bioluminescent creatures in the pitch-black depths of the ocean? Perhaps because sunlight can't reach them, they simply emit their own light... Perhaps many creatures fit Mr. Miyazawa Kenji's hypothesis. Look at this lanternfish."

Oh oh... there were cheers all around.

"So beautiful..." Cheng Shi opened his eyes wide and stared at the glowing fish swimming leisurely in the tank.

"Although the lanternfish looks ordinary, it has a crescent-shaped photophore beneath its eye. Bioluminescent bacteria live in these photophores, which are the source of its light. These lights are difficult to see in daytime aquariums. Therefore, the lanternfish's rare appearance is only seen in aquariums at night."

Ms. Sakai explained that these fish are nocturnal and control the brightness of their glow to communicate with their companions or to woo their favorites. Even Shiraizumi Masu, a marine life enthusiast, had never seen the world tonight; it was entirely Ms. Sakai's one-man show.

Suddenly, the long-standing mating topic was thrown aside, and the "glowing marine creatures" were brought up unexpectedly.

This makes the already beautiful glow of the lanternfish 10 times more beautiful.

Were all the bad plots before all foreshadowings... Bai Quanyi thought with emotion.

"Hmm... a fish that uses its own light to woo someone... How romantic..."

"Perhaps it's because we're in the pitch-black deep sea that we hope to see our companions. Also, we're glowing so that our companions can see us..."

Cheng Shi looked at the lamprey and smiled.

"Glowing in the deep sea would be very conspicuous... But even if it's dangerous, you wouldn't want to be alone, right?"

"Well, maybe it's what you said, Chengshi."

Ms. Sakai continued her explanation of "Luminous Marine Life."

Later, Ms. Sakai introduced various luminous marine creatures.

"This is a firefly squid. Its entire body glows a cyan light. It has thousands of light-producing organs inside its body. Every spring, large numbers of these glowing squid gather near the bays of Toyama Prefecture's ports. The resulting scene is a beautiful fantasy, known as the 'Firefly Squid Schooling', and it's a nationally designated natural monument. If you have the chance, you must see it! Highly recommended."

"Finally, let's take you on a grand finale of beautiful light... no, let's actually touch the fantastical light. We've prepared buckets. Please gather in pairs in front of each bucket."

Cheng Shi and Bai Quanyi sat around the bucket placed in the aisle and peeked into the bucket.

"There's water inside... What are you doing, Baiquanyi?"

“Who knows…?”

Please use the net to dip the sea water in the bucket and put it on your hands, said Miss Sakai.

They both dipped the net in water and applied it to each other's hands as she instructed.

then…….

Glowed.

In the darkness, Cheng Shi's white hands suddenly emitted a green light.

It's like holding stars in your hands.

"……what……"

Bai Quanyi stared at Cheng Shi's glowing hands and Cheng Shi's face, which was attracted by the light from his hands, and even forgot the time.

"Eh? Uh... 0.2... Big, probably Umihotaru."

"Hinamu?"

"Fireflies. The seawater in the bucket is filled with fluorescent plankton, fireflies."

The couples were talking about it.

"That's right. What's glowing in your hands are plankton smaller than a speck of dust... sea fireflies. Mix sea fireflies in water and stir, and their tiny bodies will secrete a glowing liquid. Now, please put your hands directly into the water and stir it."

The two people, immersed in the atmosphere, stirred the water in the bucket with their hands at Ms. Sakai's instruction.

I saw blue light particles like the universe coming out of the bucket.

Their fingers touched each other in the bucket.

Cheng Shi blushed silently and let Bai Quanyi hold his hand.

Ms. Sakai also paid attention to the couples who were immersed in the atmosphere and remained silent for a while.

After the aquarium event, Shiraizumi Masushi and Asai Narumi came to the hotel and carried out the same reproduction activities as the fish...

242. Take your family to a fireworks display

The cool blue sea still hits the interconnected wave-breaking structures outside the Tokyo Bay embankment, and Beika Town once again welcomes a peaceful and lazy day.

Baiquanyi opened his eyes. On his left was Yukiko, and on his right was Jinghua. They had played too late at Baiquanyi's place last night, so they went to bed in Baiquanyi's room.

Bai Quanyi sat up and looked at his two beautiful wives beside him, feeling full of happiness.

Shiraizumi suddenly remembered that there was a fireworks display in Tokyo Bay tonight, and the family could go watch it. Speaking of which, it had been ages since the family had gone out together. Although it seemed like ages, it was still less than a year, always less than a year.

In order to attend the fireworks display, Shiraizumi Masu drove his four daughters and daughter to the mall to buy new kimonos.

The four girls, dressed in kimonos, were gorgeous. They were orange, purple, blue, and red...

The one wearing the orange kimono is the pregnant Yukiko; the one wearing the purple kimono is Ikenami Shizuka holding Xiaojing; the one wearing the blue kimono is the young and beautiful Miyano Akemi; the one wearing the red kimono is the little loli Haibara Ai.

The four women around Bai Quanyi are all extremely beautiful, attracting the envy and jealousy of countless Japanese men. What kind of fairy life is this!
