Kenley extended an invitation to Daina to stay and partake of dinner together, and Daina graciously acquiesced. However, amidst this, a number of amusing incidents transpired.

  While Kenley was personally engaged in cooking and he and Tia were immersed in their tasks in the kitchen, a sudden scream echoed from a nearby room.

  "Ah!" It was a woman's voice, and it seemed to belong to Daina.

  "What on earth is happening?!" Kenley was taken aback. All had been well at home, and he hoped that no strange occurrences were unfolding.

  Kenley and Tia both rushed out. When they reached the scene, they were left in a state of bemusement.

  "Why is this device spraying water?" Daina inquired, her countenance betraying a hint of nervousness.

  To tell the truth, as a knight-captain, Daina was typically stern and unsmiling. What could possibly have occurred to cause her to lose her composure in such a manner?

  Kenley followed Daina's gaze and realized what the commotion was about.

  It was a toilet.

  It should be borne in mind that the Aude Continent was a game crafted with a medieval backdrop. Consequently, in this world, people still made use of the archaic squatting-style latrines.

  Rural peasants and common folk generally resorted to those foul-smelling pit latrines. Merchants or nobles with somewhat greater means would construct their latrines on the second floor of their abodes, leveraging the height difference to mitigate the stench of excrement.

  Nobles of high standing, who possessed castles, would build latrines on the upper reaches of the castle's outer walls, suspending them to deal with waste. But these methods struck Kenley as rather archaic. Hence, Kenley had painstakingly crafted a toilet within his own castle.

  The principle underlying the flush toilet was not overly intricate, and given Kenley's proficiency in domestic magic, he had managed to fashion it with relative ease. It was surmised that Daina, while using the toilet, had inadvertently pulled the flush valve, and the sudden chill had startled her.

  Kenley was the sole occupant of the castle who made use of the toilet. Tia, being a vampire, had no need for the facilities of the restroom. And Normani was even more exceptional; she disposed of her waste through magical means, and Kenley scarcely ever witnessed her using the toilet.

  Thus, Daina was the sole variable in this situation. Who would have anticipated that she would stealthily make her way into his restroom... Perhaps she had been in need of using it but had been too bashful to mention it to him, and so had ventured in on her own.

  "Daina, this is known as a toilet, which is, in essence, a type of pit latrine," Kenley explained, somewhat reluctantly.

  "How on earth can this contraption be employed to address the matter of defecation? Won't all the waste accumulate together? And won't it emit an overpowering stench?" Daina covered her nose and mouth, her expression one of incredulity.

  "How am I supposed to explain this?" Kenley rubbed his head, experiencing a sense of helplessness akin to that of a modern individual confronted with a primitive.

  Surely he couldn't demonstrate its usage personally? That would be utterly preposterous.

  Stolen from its rightful author, this tale is not meant to be on Amazon; report any sightings.

  At that moment, Tia's eyes lit up."Master, Tia has a solution."

  "Oh?" Kenley was piqued with curiosity.

  Tia stepped forward and, with a smile, addressed Daina."Miss Daina, do take a look."

  With that, Tia dropped a leaf of green vegetable into the toilet, then gently pulled the flush lever. Immediately, the sound of gushing water, reminiscent of a waterspout, carried the leaf away.

  "Understood now?" Having concluded her demonstration, Tia stepped back, exuding an air of demureness.

  Kenley couldn't help but burst into laughter. Tia was truly astute. He couldn't resist gently stroking her head and commending her."Hahaha, Tia, you're so intelligent."

  However, midway through his laughter, Kenley came to an abrupt halt. Something wasn't right... Tia had never used the toilet before. How could she have known how to operate it?

  Could it be that she had been secretly observing him while he was using the toilet? The mere thought sent a shiver down Kenley's spine.

  Meanwhile, Daina's eyes sparkled with excitement."What a remarkable invention! Kenley, did you conceive of this design?"

  "Well..." Kenley couldn't very well admit that he hadn't. After all, no one in this world had ever invented a toilet. Summoning his courage, he said,"I once chanced upon a description of a magical flushing device in a book. On a whim, I wondered if it could be adapted for use in toilet design, and thus, I came up with this contraption... Hahaha, it was a fortunate stroke of serendipity, I suppose..."

  "But this design is truly practical! There's no need to fret about the unpleasant odor, nor about the accumulation of waste to the point of being unmanageable. I firmly believe that if this toilet were to be widely adopted, it would surely enable more people to appreciate its allure," Daina remarked, clearly enchanted by this avant-garde design.

  Kenley surreptitiously wiped the perspiration from his brow. After all, in a medieval setting, the pit latrines utilized by numerous peasants and commoners were intolerably malodorous. And noblewomen, attired in their elaborate and cumbersome gowns, were highly likely to soil their garments when using the restroom.

  He was merely reaping the benefits of the knowledge passed down from his previous world. If he could introduce some modern technologies into this world and enable more ordinary folk to experience the advancements in life, it would surely be a worthy endeavor.

  Just imagine, being able to use a modern toilet wherever one went. Wouldn't that be a delightful prospect?

  "You are truly a genius, Kenley!" Daina exclaimed, her voice filled with genuine admiration.

  Kenley waved his hands in protest."I wouldn't go so far as to call myself a genius. However, if you're fond of this design, I would be more than happy to personally design the restrooms for your castle in the future. A toilet requires a piping system for the disposal of sewage; simply creating a toilet on its own would serve little purpose."

  "Excellent! I shall discuss this matter with my sister personally!" Daina seemed genuinely thrilled by the design.

  Kenley wiped the sweat from his brow once more, thinking to himself that it was merely a toilet... Surely there was no need for such exuberance...

  What Kenley was unaware of was that Daina had once endured an embarrassing incident related to a toilet during her childhood, which was precisely why she held such a deep affection for this design. It was as if this design had struck a chord deep within her heart.

  "Very well... Well, if there's nothing else, you may attend to your affairs," Kenley said, guiding Tia as they prepared to take their leave.

  Just then, Daina suddenly interjected,"Oh, by the way, what is this? And how does one use it?"

  Kenley turned around and immediately grasped the situation. He explained,"This is referred to as a washbasin."

  "A washbasin? Is it similar to a washbowl?" Daina inquired, a look of bewilderment on her face.

  In the context of the Aude Continent, people would store water in the washroom for the purposes of cleansing and grooming in the morning and at night.

  Kenley, finding this process cumbersome, had opted to install a complete set of facilities. He had not only constructed a water tower on the castle roof to enhance water pressure but had also established an underground cesspool. The living amenities were, in fact, quite comprehensive. With the exception of the absence of electricity, the daily living arrangements were approaching a semi-modern state.

  Kenley promptly demonstrated."Like this, turn the faucet, and the water will flow out immediately. Once you've finished washing, press this flip-up drain, and the soiled water will be drained away. It's extremely convenient."

  "Kenley... You are truly a genius!!" Daina exclaimed, behaving like a child who had never seen such wonders before. And, taking advantage of Kenley's momentary distraction, she even planted a kiss on him.
