"Good morning!" As if frightened by the sudden encounter of the three people, the indicator light on the robot's head flashed for a few moments before he said this.

"That............ What are you? "Chito was a little confused by what was happening in front of him.

"I'm the autonomous robot in charge of managing this area...... Please rest assured! I'm not going to hurt you. The robot explained.

"So can we eat that fish?"

Yuri's idea of eating the live fish had broken through the sky, and her head was filled with appetite when she saw the fish.

"No, you can't! This is a fish that I am responsible for managing and is not allowed to be intervened by outsiders, so it is not allowed to be eaten. The robot simply rejected Yuri's request.

"Sure enough, it's a fish............ Yuri reaffirmed to herself.

"If I hadn't dreamed............ The machine is talking! "Chinohe still hasn't come back to his senses at this time.

"Are you the only robot here?" The boy asked.

"As far as management robots are concerned, there's really only one in front of you."

"Good! Then forcibly use violence to eat fish! Yuri made the decision with her fast-spinning little brain melon in terms of food.

"You............" Qianhu was speechless.

"Please don't! I could have called an aggressive security robot to deal with outsiders......"

"Originally?" Qianhu chimed in.

“…… But now the communication is gone! The robot continued.

"That's just not calling!" Yuri was clever enough to hear what was out of the air.

"That's right! I want to ask, isn't the guard robot the same giant robot we encountered when we met it? The boy asked.

"Ah, the big one?" Yuri remembered.

"No, I'm afraid it's the construction robot in charge of trimming up this area. …… He and I are the only ones working around here. The self-proclaimed management robot said truthfully.

"If you look closely, there are quite a few of your kind here! What's wrong with them? The boy asked, pointing to the body at the base of the wall across the sink.

“………… I can't work anymore............" the robot gave this answer.

"Does this mean that he is already dead?" Yuri asked curiously.

"We don't have life, so we can't say it's death...... The most accurate way to say this would be the damage ............," the robot corrected.

"Huh? I realize you're just as alive as we are! Yuri said curiously.

“………… Thank you! The robot was silent for a few moments before saying this.

"The ancients even had such technology to be able to create a robot like you...... It's incredible! The boy sighed.

“…… Thank you! This time, the robot answered the boy quickly.

"So...... Since you can't eat fish, can you tell us a little bit about your robots and what's going on here? Qianhu said.

"No problem! I can show you the way...... Please follow me! The robot clicked forward.

"Na! Don't talk about it yet! I really want to eat that now! Yuri lingered at the sink for a while, then trotted after Chino.

"Shut up!" Chiho replied.

"Ah~~~~~~h

The three of them followed the robot through a slightly darker passage to a glass passage............

"Oh~~~ It's like coming underwater!" Yuri's original sense of loss was vanished by the spectacular sight overhead.

"This is the ...... under the largest sink here," the robot explains.

"Indeed! It's spectacular! The young man did not hesitate to say with praise and praise.

"That's great! I want to soak in so much water too......" Yuri thought on a whim.

"Huh?"

"Do you want to see bubbles?" The robot said.

"Is that okay?"

"Because this sink isn't in use, it's fine!" The robot explained.

"I found that there were a lot of sinks like this...... the teenager said.

"That's right! There are a total of 120 sinks in this facility, but only 12 are still in use. The robot said as he led the way.

"Does the use refer to the kind just now?" Qianhu asked.

"Yes."

"So there are no more fish in the other tanks?"

"Yes! Without. ”

The robot brought the trio to the edge of the sink and continued: "This is a production facility that produces food fish in large quantities. But now only that fish remains. ”

"So there shouldn't be a lot of food fish going to be produced here?" The boy asked.

"You're right, this facility is no longer a production facility, but you can use everything except the tank with fish............"

"Really?" Yuri asked happily.

"Really!"

"Then I want to soak in it............" Yuri said, raising her hand.

"By the way, Yuri, do you know how to swim?" The boy asked.

"Swimming? What's that............"

"Alright! I already know you've never swam before, it's dangerous! The boy said.

"There will be a way then." Yuri began to undress.

"You~~~ There are ............ here," Qianhu reminded.

"It's okay! I'll go to the door first to avoid it, and remember to call me if you have something! The boy walked out of the sink room.

"Hey!"

Yuri, who had already stripped naked, jumped into the sink and made a splash of water two or three meters high............

"Ahem! Breathe............ Cough cough cough cough ......"

"Plop puff~~"

"Poof!"

Just as Chiho was about to call for help from the boy, Yuri, who had choked on the water several times, finally surfaced............

"Oooh! Floated............" she stepped on the water with her own feet, so that she could float freely.

"What a girl with developed motor nerves!" The boy sighed.

"Are you alright?" Chiho asked Yuri, who was swimming over.

"Nothing but a little tired! ………… Na! You see I'm so tired, let's eat fish! Yuri said to the fish thief.

"Didn't I already tell you that you couldn't eat fish?" Chihu said as he knocked her on the head.

"Huh~~"

"Yuri always looks like this! I always forget memories other than food............ "Chinohe said helplessly.

"Because of my memories or something, I can continue to live!"

"Na! Especially. ”

"Huh?"

"That fish we saw before must have come out of here, right? Roar...... It's the time to do laundry......" Senho said as he washed his clothes with water from the sink.

"Ahh It's delicious...... I think so............ Feed! ”

"What?"

"You don't want to do laundry here, okay? It's going to get dirty with water. Mind you, I'm going to swim here! Yuri said with disgust.

"You're here for me to help!" Chinohe angrily threw the half-washed T-shirt on Yuri's face.

"Poof! It's so annoying~~" Yuri pretended to be disgusted and swam to the side.

"Huh?!" Chito glanced at her skillfully.

"What about environmental pollution!" The robot said.

"Environmental pollution?"

"The Earth used to be a huge living organism, but people chose to break out of it. They abandoned the natural energy cycle of water and air, and continued to build huge cities that were convenient for human survival......"

The robot transforms itself into a vertical box......

“…… It is our job to maintain the normal operation of these basic production facilities, which are the foundation of these large cities. ”

“…… Even if humanity no longer exists? Qianhu asked curiously.

"It's none of our business, it's just our job to keep this place running!"

"Hmm............" Qianhu was silent.

"Chi-chan also come down and swim together! Floating waves too! It's warm in the water! Yuri said as she patted the water in the water.

"I'll go and bring you a change of clothes first! I'll go in and swim after you for a while............" said the boy and left......

"Whew~~" Chito breathed a sigh of relief.

"Huh~~ It's really boring............" Yuri said with some disappointment.

"By the way, why can that guy swim as he pleases all at once?" Ignoring Yuri's words, Senhu asked the robot.

"I guess it's very adaptable!"

“………… Then I'll go down and try it too! ………… If Yuri can, I should be fine! …… Probably. Qianhu said uncertainly............
