"Earthworm powder? It seems that you have met an expert who knows a lot about the cleaning techniques of wooden baths! However, this kind of detergent is not only made by knowing the raw materials, but also requires the craftsman himself to have a wealth of experience and know what kind of potion is suitable for different materials of wood, which is a difficult technology to master!"

Hearing Uragaki Juzi suddenly say some relevant knowledge contained in the detergent made of earthworm powder and caustic soda, Lin Xiu immediately knew that he was looking for the right person. So he hurriedly and couldn't wait to ask Uragaki Juzi for advice:

"So, you just know who knows how to make this cleaner?"

"Hey, in my early years, I was sent by my mother to study at an upscale Japanese inn in Kyoto, and that's where I met craftsmen who used earthworm powder and caustic soda to prepare detergents. At the time, I remember him using his tongue to tell if the ratio of potions was appropriate......"

Uragaki Juko raised his head, carefully recalled some of the past events in the early years, and couldn't help but sigh secretly in his heart that time flies.

"Can I ask where the master who used these two potions to prepare the detergent is now?"

"Ah...... I'm sorry, I just accidentally remembered some things from my youth, and I just felt a little emotional for a while......"

Mei Yuan Juzi calmed down the emotions in his heart a little, and then picked up the teacup on the table in front of him, took a sip gently, and then said calmly to Lin Xiuyi:

"When I was studying in Kyoto, I met Kirimura, a cleaner at Kirituraya in Kyoto, and I remember that he used caustic soda and earthworm powder to remove stains from the wood in the wooden baths, and I was very impressed by him. At that time, my mother arranged for me to go to Kyoto's famous Kamihaya to learn about inn management, and my first job in Kamihaya was to clean the baths used by the guests, and Kirimura happened to be the bath cleaner at Kamihaya at that time. ”

"Because I am often exposed to it at work, I have some knowledge of the cleaning agent formulas of Kirituraya. At that time, as long as there was a need to clean the bath, Master Kiritura would come to the door alone with tools, and every time he prepared a detergent, he would not shy away from me, I once asked Master Kiritura, aren't you afraid that I will learn his formula? He told me at that time that the two ingredients he used were caustic soda and powdered from dried earthworms. As for the specific ratio, the craftsman needs to use his tongue to distinguish whether it matches the wood that needs to be cleaned. ”

"I remember he showed me a demonstration of how to dip his finger in a little bit of the prepared detergent and put it in his mouth, taste it and spit it out immediately. After his demo, he asked me if I had the courage to give it a try. I was very unproductive at the time, I just dipped a little powder in my fingers, and I couldn't help but spit it out as soon as I held it up in front of my eyes, and now that I think about it, it's so embarrassing......"

Listening to Uragaki Juzi narrate his experience when he was young, Lin Xiuyi couldn't help but be moved by Uragaki's experience. Especially some bits and pieces of memories when he got along with Master Kiritura, it can be heard that Uragaki Juko has great respect for Master Kiritura, but in addition to respect, there is also a friendship like a friend.

"Chef Kiritura sometimes complains to me that there are fewer and fewer people who are willing to settle down and learn how to clean wooden baths with him. He was approaching retirement age, but he had never been able to find a suitable successor for his craft. The traditional wooden bath cleaning technique is probably going to be lost after him......"

When Umegaki Juko said this, her expression was also a little lonely, maybe she thought of the care that Master Kirimura took care of him back then! But the answer that Lin Xiuyi is most concerned about now seems to be about to come out, how did Fujiki Minato's ability to clean the wooden bath come about, it will not be something she figured out out of thin air.

"Boss, can I ask where Master Kiritura lives now, and to whom did his skill of cleaning wooden baths end up?"

Lin Xiuyi saw that Mei Yuan's bow suddenly stopped, so he hurriedly asked Mei Yuan's boss.

"Master Kiritura, it seems that I passed away due to illness not long after I returned from Kamihaya. As for his craft, there should be no one to inherit it. Kirituraya officially closed down after the death of Master Kiritura......"

"No, doesn't Master Kiritsu have no children and relatives? Lin Xiuyi suddenly asked a little anxiously.

"Children? Master Kirimura told me that he had a daughter, but his daughter was admitted to a prestigious university in Tokyo, and even Master Kirimura had no hope that she would come back to inherit the family business, and the work of cleaning the bath was basically done by men, so how could this craft be passed on to women?"

"Daughter, you mean, Master Kirimura also has a daughter!"

Lin Xiuyi finally showed a satisfied smile on his face, this time the trip to Meigaki House finally did not return empty-handed. Since Master Kirimura also has a daughter, it seems that the woman's age should be slightly older than Uragaki Juko, so it seems that Minato Fujiki should be the only daughter of Master Kirimura. And this inference explains why Mina Fujiki has mastered the art of cleaning wooden baths.

"Hey, but she was admitted to Ochanomizu University back then, so she won't come back to inherit Kiritura's things anyway!"

Ochanomizu University! I was admitted to Ochanomizu at that time, so it was unlikely that I would come back to inherit the family business. But it is very likely that Master Kirimura's daughter is Minato Fujiki. Although I don't know why an elite woman who was admitted to Ochanomizu University decades ago would earn a living by working as a cleaner in her later years. But Lin Xiuyi vaguely felt that there must be some unknown reason hidden in this. As long as you follow this clue, you will definitely be able to find the real motive of the suspect for killing Professor Eiji Noguchi.

"So, Lady Ugaki, have you ever met this daughter of Master Kiritura, or have you heard something about her?"

Lin Xiuyi was nervous and expectant and asked the latter key question to Ugaki Juzi, but Uragaki Juzi only thought for a moment before shaking his head regretfully at Lin Xiuyi.
