"We are indeed responsible for processing the ingredients used in Happy Hour Restaurant, but we are only responsible for processing them."

Makoto Ikedo explained as he led everyone to visit the processing site.

"The person who will be liaising with you is Ms. Akiko Hiemori of Maruyama Foods, right?"

Nanatsuki Koshimizu took out a photo of the deceased. Makoto Ikedo looked at the photo and nodded, "Yes, she was responsible."

"I wonder if she came here last night?" Tang Ze asked, staring at Ikedo Makoto.

"No, she didn't come last night." Iketo Makoto shook his head to indicate that he had never seen the other party.

As everyone was talking, they walked into the factory, and soon a delicious smell filled the air.

Everyone followed the source of the smell and saw a large barrel that was nearly 1.6 meters high and 5 meters wide.

And in this big pot, there is a milky white soup.

"This soup smells delicious." Nanatsuki Koshimizu tiptoed closer to the big pot and saw the milky white soup inside, which looked very appetizing.

"This is sauce." Ikedo Makoto corrected with a smile, "It's not cooked yet, so it looks like soup."

"Eh? But this machine says 'Top Soup'." Nanatsuki Koshimizu pointed to the logo on the machine.

"This machine can make soup and sauce," Iketo explained. "It's a dual-purpose machine."

"I see. If you don't see these machines, you really wouldn't realize how advanced they are." Koshimizu Nanatsuki sighed, then changed the subject and said, "By the way, do you get regular checkups at the health center?"

"Ah, of course you can ask Ms. Masui at the health center." President Ikedo nodded. "She's in charge of regular checkups in Haido Town."

"The businesses we investigated previously that did not undergo regular inspections were in the areas that the other party was responsible for."

Detective Mizukura added quietly, then looked at Ikedo Makoto and said, "Excuse me, do you have a menu for the food you wholesale to Happy Hour? I'd like to see it."

"Of course, I'll find it for you right away." After hearing what Detective Mizukura said, President Ikedo hurriedly ran to get a menu.

"There's so much variety! Are all these dishes made here?" Detective Mizukura exclaimed as he flipped through a brochure that looked like a cafeteria menu. "Isn't this similar to the Happy Hour menu?"

“In fact, Happy Hour Restaurant has very high requirements for ingredients, and it takes a lot of effort for us to prepare them.”

President Ikedo explained, “The ingredients used in all the dishes here are personally selected by their boss, President Abe.”

"Specialized ingredients?" Detective Mizukura's expression changed. "Excuse me, where are they from?"

"They are all purchased from Maruyama Food Wholesale Company." President Iketo complained a bit when he said this.

Nanatsuki Koshimizu and Karasawa looked at each other, and everything was said without words.

Now it seems that the previous speculation was not groundless. Food poisoning may have a very secret connection with Akiko Hiemori's death.

The two cases seemed to be connected by a faint thread. Tang Ze had a hunch that if he could solve the truth of one of the cases, he would also be able to get the answer to the other case.

However, neither Karasawa nor Nanatsuki Koshimizu talked about the murder case. They just waited for Detective Mizukura to finish questioning and planned to leave together afterwards.

"President, the soup-making machine is broken."

Just as everyone was about to leave, the middle-aged man who was directing the workers suddenly ran over anxiously and said, "I just tried a little bit, and it tasted wrong. It's not as delicious as before."

"What's going on? Hurry up and contact the people from Lichen Manufacturing and ask them to take the machine back." Upon hearing this, Ikedo Makoto's face changed and he said dissatisfiedly, "Have them check it carefully to see what the problem is!

If the customer notices something is wrong, we will be the ones to be blamed!"

"I understand." The middle-aged man beside him nodded quickly.

"I'll go over and take a look too." Makoto Iketo said "Excuse me" to Tang Ze and others, then hurried over to check the situation.

When Tang Ze and others saw this situation, they did not disturb them too much and left the Ikedo Food Processing Plant directly.

"Then we'll take our leave from now on."

After leaving the factory, Detective Mizukura said, "I've received intelligence that more people have been revived after the rescue efforts. We need to question them one by one and find the pathogen as soon as possible."

"Aren't you waiting for the results from the Scientific Research Institute?" Nanatsuki Koshimizu asked.

"Honestly, based on past experience, if we haven't found it by this time, I'm afraid it will be difficult to find the source among those specimens."

Detective Mizukura smiled and said, "After all, many ingredients were put together before sampling. Even if we can't be sure which ingredient it is, there should be traces of pathogens.

If nothing has been found at this point, I really have given up hope."

As if to verify each other's words, as soon as the other party finished speaking, their phones rang almost at the same time.

After answering the phone, the two listened silently to the report on the other end and sighed at the same time.

The answer is obvious. Scientific research has not found the carrier of the pathogen, and there is no problem with the various ingredients in Happy Time Restaurant.

Obviously, the most troublesome situation occurred.

In fact, both of them were mentally prepared for this result. Detective Mizukura was prepared because of his accumulated work experience, while Karasawa was prepared because of his premonition of the case.

After all, once a case is related to him, it will always be difficult. If the pathogen can be found so easily, then the case will be 80% solved.

Although there is still no evidence to prove it, Tang Ze just has this feeling.
