"Mr. Asker, who is this?" Suddenly, a man in a green suit and glasses appeared. "This is a classified area."

"If you agree that chestnuts are fine as long as you don't eat too much," Grigory replied, holding out a note. "If I'm not mistaken, from the label of the two of you's office, he's your boss, and that's Mr. Shibuyani's permission slip."

"Mr. Shibuyani's permission slip?" The man with glasses took the permission slip with some surprise. “。。。 All right... Don't walk around with him, or I don't mind thinking I didn't see the note. ”

"Of course." Gregory shrugged.

。。。

In the ward, the agent who was hanging the water heard the sound of the door opening and immediately reluctantly turned his head around.

"Here comes the chestnuts you wanted," Grigory explained, pointing to the bag. "The bag was broken on the road, so I bought a bag on the side of the road."

"Chestnuts... The agent was too weak to make any obvious statements, but his mood was clearly better.

However, when Chiba peeled a chestnut and fed it to the agent, the agent refused.

“？” Gregory looked at the agent's affection, somewhat stunned. "What's wrong?"

The next moment, Gregory and Thousand Feathers were dumbfounded.

After all, what if a person who loves chestnuts asks "what is this?" This is clearly problematic.

"Then you know," Grigory said, pulling out an unshelled chestnut from the bag and showing it to the agent. "What is this?"

The agent gave a blank look at the answer.

“。。。” Grigory groaned, only to see the agent's eyes change from blank to blank. "Hello? Feed!? ”

"He's unconscious?" Qian Yu asked tentatively.

"yes, so..." Gregory took a deep breath and walked out of the room with Chiyu. "Let's go buy something."

When the two went out, they happened to run into a female doctor in a white coat.

"Mr. Gregory," the female doctor spoke, and after the female doctor spoke, Chiba realized that this was the owner of the female voice who had previously introduced Grigory to the patient's condition. "Have you identified the cause? A cause that can overturn the old man's isotope assassination theory. ”

"Do you want me so much to be able to overturn that guy's diagnosis?" Grigory raised an eyebrow.

"If you deduce that the disease is better treated than the old man thinks the isotope is, I want you to overturn him." The female doctor said seriously. "Well, can you do it?"

"Hmm... Gregory's expression was a little subtle. "How can I say it... If my assumptions are correct, it is indeed better to treat than the old man's diagnosis, but the treatment will not change. ”

"Huh?" The female doctor and Qianyu were confused together.

"Then, I'll go with this kid to see if our inference is wrong, you can prepare a herbal soup of Cordyceps for this patient first." Grigory said as he pulled Chiba and prepared to leave.

"Cordyceps?" The female doctor was surprised. "What's that?"

"An herb from far east and west that parasitizes insects," Grigory explained. "Feeding the patient during treatment can effectively reduce the erosion of radioactive poisons (i.e. isotopes) on the body... So far, this result has only been confirmed by monkey test subjects, but it may be possible to give it a try. At least there won't be a negative effect, will it? ”

"Oh... The corners of the female doctor's mouth twitched. "Monkeys..."

"Anyway, you can do it," Gregory and Thousand Feathers disappeared into the stairwell.

。。。

Outside the fruit shop designated by the agent.

"This is the fruit shop he designated?" Gregory looked at the name of the fruit shop in amazement. "Sure enough..."

Before Chiba could ask what was going on, Gregory walked in with Chiha.

“Castanhas？” As soon as Grigory walked in, he spoke in an unknown language in a strange tone.

"Ahh The owner of the fruit shop actually understood Gregory's language, and after making a clear sound, he took a bag and approached a fruit grid in the distance, and began to load it.

"What language is this?" Qian Yu said speechlessly. "That agent was assigned to work in Bolivia, is that the Spanish used in Bolivia?"

"No," Gregory looked at Chiba as if he were a rookie who had fallen into a trap. "You've fallen into a thinking trap."

When the fruit shop owner handed over the bag full of the fruit requested by Gregory, Qian Yu looked confused - he had been using a certain language to buy chestnuts from the fruit shop owner who didn't know where to hide, but the dried fruit in it was obviously not chestnuts.

"What is this?" Qian Yu asked.

"Brazil nuts," Gregory's face immediately sank, and he took a few dried fruits from the bag. "You go home first, I'll go back and deal with this patient before I go back. Take the rest of these dried fruits back and eat them, don't eat too much one a day. ”

。。。

Tokyo Metropolitan Police Department, Public Security Department, an office.

The female doctor is sitting in the office filling out paperwork, while the man in green and glasses is waiting for the female doctor to fill out the paperwork she needs.

At that moment, the door was violently pushed open, and Grigory burst in with a visibly unhappy look.

"Doctor As, you're finally back." The female doctor was about to greet her, but was immediately questioned by Gregory.

"Idiot!" Gregory burst into foul language.

"Who are you talking about?" The female doctor asked, somewhat surprised.

"Anyone who knows that the agent is actually in Brazil, not Bolivia!" Grigory snapped.

"Brazil?" The female doctor repeated this and turned her gaze to the man in glasses in green. "Mr. Kazami, is what he said true?"

"Looks like you're the idiot who knows this but doesn't tell us?" Grigory asked.

"Is there any difference between Brazil and Bolivia?" Kazami asked rhetorically. "Same area, same parasites, same diseases...

Before he could finish his sentence, he was interrupted by Gregory, who had an expression of "hatred of iron does not make steel". "But not the same language!"

“？” Kazami's expression turned to confusion.

"In Bolivia, chestnuts are chestnuts!" Grigory said exasperatedly. "But in Brazil, chestnuts stand for As Castanhas do Para, which means chestnuts from the Para tree, because no Brazilian is stupid enough to call them Brazilians – nuts!" (nuts, nuts in English, and idiot, here Gregory reread this word in order to use this word to scold the wind)

With that, Gregory shook the Brazil nuts in his pocket in front of Kazami and slammed them onto the couch where Kazami was sitting just now.

"Okay, so what?" Kazami asked rhetorically. "So what?"

"Brazil nuts are one of the richest foods in the world in selenium, and excessive intake of selenium can cause fatigue, vomiting, skin inflammation, nail loss, and hair loss.

“。。。” Kazami's momentum immediately drained away, and he lowered his head and said nothing.

"So, how do you treat it?" The female doctor asked.

"There's no need to do anything else," Gregory said lightly, no longer aggressive. "The chelated dithiopropanol that is being used now is used to wash away isotopes, but it is more effective in treating selenium poisoning caused by nuts."

"I'm here to tell you the truth, just because if you follow the direction of the isotope, it would be better to embezzle the money and give your men a precious vacation."
