"So, he put sodium hydroxide powder in it?" Gregory looked at Takasugi's confession and snorted. "It's really the young lady's luck - the pills she used to cover up Toshihiko Takasugi's murder actually had multiple tablets of vitamin C in the pills she used to feign suicide, and that thing had a neutralizing reaction with sodium hydroxide...... Except for a little too much sodium in the blood, there was almost no effect. ”

"Put sodium hydroxide," Qian Yu was also speechless. "It's what you can find...... But can this thing really poison people? ”

"If you really want to poison people, you need to fight against corrosiveness, right? I don't think there's much hope," Gray Hara snorted softly. "After all, these medicines have probably been corroded by lightning all the way before they reach the organs that can absorb them."

"Leave them alone, the right thing to do now is to get her relatives and friends to calm her emotions and wait for the next round of symptoms to attack - since you can have a sudden symptom in a calm state, it is only a matter of time before you have a second sudden attack, and it will never be long."

"But that Matsumoto Kiyocho, I really didn't see that he was such a ruthless person, and he actually left his daughter like this." Gray Plains shook his head.

"This ...... Actually, it's not that I can't understand it," Qian Yu showed a wry smile. "Don't forget, what kind of dress is the patient in right now...... Even if it's a biological father, it's a little inappropriate to be there, right? ”

"Even male doctors can go, and there's nothing wrong with my father, right?"

"Another reason why I finally decided to choose the two of them is that both of them are no longer nervous children when they see naked people of the opposite sex, and even if they are asked to go to the private parts of the opposite sex for a detailed examination, they will not waste any time because of hormones." Grigory said slowly. "Other interns can only be used as half a person, and both of them can be regarded as a whole person."

Suddenly, there was a loud alarm bell in the office – this alarm bell connected to Gregory's own special ward, which meant that the medical staff were making an emergency pager from there.

The frequency is more complex than the usual alarm bells, suggesting that it is not only his assistants who are being called, but also Gregory himself.

"Looks like we've found something, let's take a look." Gregory immediately stood up and beckoned Chiba and Gray Yuan to come with him.

……

When Gregory arrives in the ward with Chiba and Ashbara, he finds the room in chaos - of course, the most striking thing is that Fujiwara is riding on the thighs of the struggling Sayuri Matsumoto, pressing her hands, while Hotaru presses her hands on the chest where Sayuri's hospital gown is unfastened, as if ripping open Sayuri's chest and examining something.

"......" Chiba subconsciously glanced at Kazumi Takenaka, who was next to her with a frightened face, and after realizing that the other party did not have any idea of asking for help, she confirmed that this was some kind of forced medical treatment.

"Uh," Grigory was taken aback by the rather delicate scene in front of him. "Is something wrong?"

"She had a blister on her chest that showed severe itching, and I was looking for a chance to observe, but she kept scratching, so we had to control her first," Hotaru said, noticing Gregory's arrival. "Could it be a food allergy? Did she eat anything new that she hadn't touched before? ”

"Food allergies can't explain lung scarring, unless you're going to think that the symptom we've just been waiting for isn't from the same source as the scarring that came before." Fujiwara reminded. "And seriously, shouldn't we get rid of her blisters first......

"You know what to do," Gregory shook his head, and walked out of the room with Thousand Feathers and Gray Plains again. "Oh yes, after quieting her down, remember to ask her if she went to any strange places, and then ask her for the keys to her house, we need to do a toxicology search."

"Do you want to check your blood again?" As they walked out of the room, Qian Yu said suddenly. "And check the hair or something."

"Of course." Grigory nodded, then removed his badge from his chest. "Little girl, take this, go to make an appointment for what you think is necessary, remember to ask for a little more lemon tea to make up for a round of difficult ingredient tests, the little guy will clean up, and prepare to go with me."

The rationale for this riddle is actually quite simple – an enlarged tongue, itchy skin, and fibrosis of the lungs can in fact all point to the same cause: heavy metal poisoning

This is a reasonable assumption when someone has poisoned her just now, especially when they find out that the groom who poisoned him claimed to use sodium hydroxide, which has very limited lethality, rather than other poisons that can actually be used to kill.

In such cases, the thing to do is to check the patient's hair and blood samples (the previous emergency electrolyte check did not check for toxins) and at the same time check the leftover drink - if these heavy metals are from the poisoned groom, then this is definitely faster than checking the patient.

……

"Did he turn himself in?" Sayuri Matsumoto asked, lying on her side on the bed, topless.

"yes," Gray said as he pressed the allergy test plate against her back. "The poison is sodium hydroxide, which has a certain degree of neutralization with the vitamin C tablets you added, so you're fine."

"Vitamin C," Sayuri Matsumoto murmured as she gently grabbed Kazumi Takenaka's hand in front of her. "That's a ...... I never thought those little pills would have this effect. By the way, Yimei, did you use such a shameful test method before? Take off your clothes, you can't even wear a bra or anything. ”

"Ah, you mean when I tested for allergens?" Kazumi Takenaka gently rubbed Sayuri Matsumoto's hand and said with a smile. "No, because it was a male doctor who showed me at the time, he gave me a patch allergy test of diclofenac and celecoxib on his arm."

"That effect is not as good as this, and we generally use the upper back when we have the conditions."

"Is it really necessary?" A small drop of a potential allergen is placed on the location indicated on the allergy test plate, and then multiple disposable needles are used to gently puncture the skin in the corresponding location to allow the allergen to enter the skin, Hotaru asked. "In any case, your father's affairs are not intentional, why should you condone the other party's deliberate murder of you because of such a thing, and still cover for him?"

"Because I might have done the same thing if I asked myself, I don't think I'm in a position to blame him......" Sayuri Matsumoto sighed. And seriously, I love him, I really love him - ah! ”

"I'm sorry!" Hotaru hurriedly stopped what she was doing. "Did the needle hurt you?"

"No," Sayuri Matsumoto suddenly began to moan. "It's my calf!"

"Huh?" Hotaru was stunned for a moment. "Calves?"

"......" Gray Yuan Wai reacted quickly, and immediately lifted the quilt - but there was nothing unusual on the calf.

"Ahh Sayuri Matsumoto let out a wail of severe pain again. "It hurts! Hurt! It hurts!! ”

"It could be neuropathic pain," Hotaru said to Ashbara. "Go and open Gabapentin."

"It can't be lupus," Hotaru muttered quietly. "Although some symptoms do not match, this thing is known for its strange and unpredictable symptoms......
