Ke Xue: Picked up a bottle of sherry at the beginning

"Are we dating?"

"What do you say?"

"It feels amazing."

in the crowd.

"I will be the guide for all the guests who came here today. I am the staff of Hanaka Aquarium——Sakai. When you hear "Visiting the Night Aquarium", what is the first thing that comes to your mind?"

The guide Ms. Sakai asked Shiraizumi, who was standing at the front of the couple group, a question.

Bai Quanyi said: "Uh... I thought of visiting the tank under the night... Recently, it is popular to use cyan LED lights for aquarium activities at night. The blue light is very suitable for the tank at night."

"It seems that he is a handsome guy who knows a lot about new things in the aquarium. Your girlfriend is so beautiful. Are you looking forward to tonight's 'Couple Only' event?"

"Is it because you want to stay overnight? But it's just a bed on the floor to watch the sink?"

"No, no, no. Think about it... this excursion is a "night" excursion~"

"Oh……"

"Speaking of the night...for example, the night snack eel pie. It's not only delicious but also nutritious, but it's not recommended for children~? The reason is the same."

What is she talking about... Cheng Shi tilted his head.

"So, the main dish I bring to you tonight is the life that the fish love at night. Hehehe..."

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

Noise...noise....

It turns out that "night" also contains this meaning...?The couple group made a noise.

"Watching the adult life of fish at night? Is this an activity only adults can participate in?"

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

"Then, hurry up and watch the night love life of the fish. The reproductive behavior of the fish is in vitro fertilization, so they will not mate. The reproductive activity of the fish is very beautiful."

· · · · · · · · · · · · · · · · · · · · · · · ·

Ms. Sakai is very excited for some reason.

"Compared to the aquarium during the day, I prefer the aquarium at night. Because most fish breed at night, just like the human couples here today."

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

Asai Chengshi giggled and said, "I think it's quite interesting."

Under the leadership of Ms. Sakai, everyone visited again in front of the medium-sized tank with a southern flavor.

"Among fish, there are those who practice monogamous married life like us, and there are also those who follow the law of the jungle. The powerful male fish create a harem. That kind of male fish that creates a harem to reproduce is very bad!"

…………

Narumi Asai chuckled and said, "Mr. Bai, you are that powerful male fish."

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

The lady tour guide enthusiastically introduced: "As long as the creatures in the world are male, they will definitely pursue beautiful women. Otherwise, the creatures will not be able to evolve. Well, please look at the water tank here. This is the protuberance of the night. Fish. Ahhh, they're very active...the male and the female breathe together, lay eggs—"

A female fish swished and jumped vertically to the top of the tank.

The male fish army began to chase the female fish in a swarm.

then.

"Look. Now it's spawning! Then there's a lot of sperm from the males. Ahhhh... the love life of the fish. It's so beautiful no matter how many times I watch it."

The water in the sink looks a little cloudy, could it be because... the couple group is whispering to each other.

"Every night they release eggs and sperm all over the tank like this. A lot of fish don't get excited until sunset, so it's only at night. Ah, it's on again! How do you guys feel? Look , they are coming!"

"It's very difficult for males and females to succeed if they don't cooperate with the rhythm. This is the same as all human beings!" Ms. Sakai explained excitedly.It seems a little too excited.

"Tropical fish are especially mentioned here. They reproduce every night. If you compare it to humans, it's like people in Latin countries? Warm climates make people go into heat. Ah, this time it's a butterflyfish couple!"

Bai Quanyi twitched the corner of his mouth, this young female tour guide is too dedicated. [-].

Chapter 241 Breeding Activities

I thought it should be a more romantic date, but the focus of Ms. Sakai's introduction is getting more and more biased...

"That... Ms. Sakai? It's a rare visit to the night aquarium. Is there anything else besides breeding activities..."

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

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

"The clownfish is a super-sport fish species. And! Only the strongest one in the group will become a 'female'. The losing clownfish will all become males... It's feminism."

"Ehhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh?"

"Chengshi, if you are a clownfish, you must be the strongest one." Bai Quanyi said with a smile.

Ms. Sakai continued her explanation of sexual transition.

"Among fish, there are many species that can change sex! Compared with "[-]", the cleft lip fish here originally had only females. The strongest individual in the group will become a male. And the time to become a male Only one hour. The male leader can possess all the females in his group, like a harem!"

"Put all the females into the tank, and the strongest individual among them will become a male. There are many fish that satisfy this rule. Conversely, if many males are put into the tank, the original males will become females. Such fish will adjust the sex ratio according to the environment. This kind of thing also exists in the human world! For example, in prisons..."

Ms. Sakai explained with a hearty smile, and Bai Quanyi was amazed at this: "...In American prisons, women are often played as the role of the weakest prisoner...you mean this."

After a sex transfer class, all headed to the Shark Tank.

"Look! The shark is riding on the back of his partner, biting him with sharp teeth!"

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

"Oh, because sharks are special! Look, look, look. In order to prevent the female from running away, the male bites each other like this. It's so wild, hehehehe, and then take advantage of the female's powerlessness to resist!"

"Bai Jun, I think yours is stronger than sharks!"

Asai Chengshi has personally experienced Shiraizumi's human weapon, which is even more powerful than the Chaowei Blue Cat Invincible Cannon!

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

It's actually Bai Quanyi's first time seeing a shark, and it's just too raw... so rude...!

"Bai Quanyi... Are you implying me in a detour... want to tell me 'I'm about to eat you'?"

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

Miss Sakai approached her face, and asked Asai Chengmi in a low voice: "Miss, can't wait to have breeding activities with your boyfriend?"

Asai Chengshi said: "No, besides, she just..."

Ms. Sakai glanced at the powerful and handsome Bai Quanyi: "Wow! I'm so envious!"

And so, the final event came.

"The lights in the aquarium at night are not LEDs. After the breeding activities, as everyone knows, it's sage time. So... what you will see next is marine life that emits a romantic glow..."

Walking on a dark circular road, Ms. Sakai said, "This is a spectacle that can never be seen during the daytime." She called everyone to watch the "luminescent biosphere" that made her proud.

"In the deep sea where you can't reach your fingers, why are there so many glowing creatures? It's because sunlight can't reach, so let's just shine by yourself... Maybe there are many creatures that satisfy Mr. Miyazawa Kenji's conjecture. Please look at the light eye fish over here."

Oh oh... There were cheers all around.

"It's so beautiful..." Chengshi opened his eyes wide and stared at the glowing fish swimming leisurely in the tank.

"Although the appearance of the lampeye fish is ordinary, there are half-moon-shaped light emitters under the eyes. The light emitters live in bacteria that emit light, and they are the source of light. It is difficult to see these lights in the tank during the day. So the lampeye fish A rare gesture, only for night aquariums."

This fish is a nocturnal creature, and by controlling the brightness and darkness of its light, it communicates with its companions or courts someone it likes, Ms. Sakai explained.Even Shiraizumi, who likes marine life, has never seen the world tonight, and it is completely Ms. Sakai's one-man show.

Suddenly throwing aside the rotten copulation stalk, he suddenly brought out "glowing marine life".

This makes the brilliance of the already beautiful lampeye fish 10 times more beautiful.

Could it be that the previous rotten memes were foreshadowing... Bai Quanyi thought with emotion.

"Hmm... a fish courting with its own light... very romantic..."

"Maybe it's because it's a deep sea world where you can't see your fingers, so you want to see your companions. At the same time, the reason why you shine is to let your companions discover..."

Chengshi looked at the lamp eye fish and smiled.

"Glowing in the deep sea will become very conspicuous... But even if it is accompanied by danger, I don't want to be alone."

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

Ms. Sakai continued her explanation of "Glowing Sea Life".

Later, Ms. Sakai introduced various glowing sea creatures.

"This is firefly squid. The whole body emits blue light. There are thousands of light emitters in their bodies. Every spring, a large number of glowing firefly squid gather near the bay in the bay of Toyama Prefecture. It is like a beautiful forest. The fantasy scene, known as "firefly squid swimming in the sea", is a national natural monument. If you have the opportunity, you must go and see it! It is highly recommended."

"Finally, let's take everyone to watch the beautiful light of the finale... No, it should be directly touching the light of fantasy. There are buckets prepared here, please gather in groups of two in front of the buckets."

Cheng Shi and Bai Quanyi sat down around the bucket placed on the aisle, spying on the bucket.

"There's water in it...what are you going to do, Bai Quanyi"

"who knows……?"

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

The two of them dipped the net in water and put it on each other's hands as she said.

then…….

glowed.

In the darkness, Cheng Shi's white hand suddenly glowed blue.

It's like holding a star in your hand.

"……what……"

Bai Quanyi stared at Chengshi's glowing hand, and Chengshi's face attracted by the light on his hand, even forgot the time.

"Huh? 0.2 Uh... Big, probably Hai Ying"

"Hai Ying?"

"Sea firefly. The sea water in the bucket is filled with fluorescent plankton sea firefly"
