Although the speculation was a bit overreacted at this time, Chiba believed that it was necessary.

Radio interference, staff in chemical hazmat suits, metal utensils glowing blue, the first point means that the visitor is certainly not hospitable, and the second point means that it may be a chemical poison......

The auxiliary unit gave further visual details when Qian Yu thought of this - the head of the chemical protection suit was very large, obviously more than the space that the chemical protection suit would reserve for the head for free movement purposes under normal circumstances.

Since you couldn't see any special equipment on the chemical protective suits when you observed them just now, maybe they had a built-in air breathing apparatus or a filter that could filter out the things they spread over their heads, right? In other words, their hazmat suits are airtight suits for airborne viruses, which also means what airborne toxins they may have released.

In the face of gaseous toxins, it is necessary to take the highest level of countermeasures in all aspects.

"Hurry up and find out if there are any plastic bags and duct tape!" Conan spoke to everyone, and he began to look for it. "Hurry up!"

"I'm going to fill the tub with water." Chiba also reacted immediately. "Gray Plains, you go and turn off the air conditioner! Then check all the windows and turn them off! ”

Because the water in the bathtub has to touch the body, the water quality must be able to meet the high standards that even children can drink safely, so Chiba will release the water to reserve drinking water. (The water is absolutely safe at first, but after a while, it is likely to be contaminated with air toxins, so it needs to be in the shortest possible time) and the reason for Ashbara to turn off the appliances and air conditioners is because the air conditioners will draw toxic gases from the outside, and turning off the air conditioners will prevent the potential deterioration of the situation before they can find something like tape.

Just as Chiba turned on the tap in the bathtub and closed the bathroom window, he suddenly felt himself hear the whispers of Gray Plains. "Oh my God......"

“？” Before Qianyu could go back to see what was happening, Gray Yuan Wai had already walked over.

“Sarin！” Ash Yuan said in a low voice after taking a look at it and making sure that no one was paying attention to her except for Chiba, and no one could hear what she was saying. "It's exactly the same scene I've seen from Sarin's gas experiments before!"

"Sarin gas?" Qian Yu was startled, and only asked after a second.

"......," Gray Yuan nodded.

Sarin gas, a pesticide developed by Farben in Nazi Germany during World War II, was later reused as poison gas. (Although sarin was eventually assigned to the artillery unit, they did not ultimately order the use of the weapon.) Later, it was used as a military resource reserve by the United States and the Soviet Union in the first half of the fifties, and became NATO's standard chemical weapon. Just last year, 162 countries around the world signed the United Nations Chemical Weapons Convention, agreeing to completely destroy the more than 15,000 tons of sarin gas that existed (the exact figure is 15,047, but you can't expect Chiba to remember in such detail) by April 29, 1997.

The principle of this poison gas is to attack the human nervous system, so that the poisoned person loses control of his muscles, and eventually dies of suffocation caused by the inability to breathe. Moreover, this poison is very effective, and its lethal concentration and duration of effect are among the best in chemical weapons.

But in this case, this distinction is fatal.

"Hurry up!" Chiba's expression became anxious. "If it's sarin, it's a big problem!"

"Doctor," Conan's voice came from outside. "You haven't wet your towel yet—ah, Doctor, haven't you gone yet?" Ok......"

"I still have a figure out what to do at this point," the doctor said with a smile. "Wetting a towel in the face of this kind of attack only makes it worse, so how could I possibly do such a thing?"

"Conan, tape!" Ayumi took a wide roll of tape and pulled her head out between her luggage.

"Okay," Conan ran to Ayumi's side and took the tape. "Mitsuhiko Motota also comes here, you can put the tape I tore off and stick it on the gap in the window and the gap on the left and right sides of the door. Doctor, you press the towel against the wider crack of the door below! Chiha, do you need duct tape over there? ”

"Deal with this side one last," Chiba replied. "The windows here are sealed with rubber rings. In other words, don't you have to deal with the ventilation ducts of central air conditioning? ”

"It has to be dealt with, but it has to be done in order."

………… More than two minutes later.

"It should be fine...... "With the faint light of the mobile phone screen, Qian Yu looked at everything around him and whispered. After all, even-"

"Poof!" Before Thousand Feathers could finish speaking, they heard a sound that sounded like it was coming from next door, and it was very similar to the sound of something falling to the ground—a sound that only a soft weight like a human could make.

Maybe this means that there is a less vigilant person next door who has been tricked.

And it is likely that this is not the only victim—it is almost eleven o'clock, and some of them may have fallen asleep, and they will wake up in agony in their sleep, and then meet the arrival of suffocation like a dead man in the pain of paralysis and suffocation.

Thinking of this, a trace of fear flashed through Qian Yu's heart, and then he felt a slight tremor coming from beside him.

He then felt two small hands lightly on his arms—even through his clothes, Chiba could feel what the two little hands were transmitting physically and emotionally.

Physically, it is a tremor of fear, and emotionally it is an empathetic grief.

Although they are alive and kicking, they are only one step away from death.

Qianyu, who was aroused by the gray plain's mourning, began to observe again whether all the hidden dangers had been dealt with out of instinct. It looked like the protective measures were already very perfect, but now it looks a little unsafe.

"What if I'm scared?" Ayumi's somewhat aggrieved voice suddenly broke the long silence.

"Don't be afraid...... Conan said halfway through, but he seemed to think of something. Let's sing, and we won't be afraid when we sing. ”

"Singing?" Ayumi said curiously.

"この世であなたの愛を手に入れるもの (Komatsu Mibu's "Mystery", which was sung by the Young Detective Group in the underground secret passage in the third part. Conan made a start for Ayumi - I don't know if it's providential, Conan, who usually sings out of tune, actually sings in tune.

Immediately afterward, everyone sang unevenly as if they had found a spiritual pillar under pressure.

"踊るライト見つめて忘れない......"

"Ahh 謎がとけてゆく......"

The singing echoed through the room until the sound of an ambulance's horn came from afar.

"Saved......" Ayumi's trilled singing stopped abruptly, replaced by a cry that rang out instantly. Finally saved......"

Qian Yu also breathed a sigh of relief at this moment, and looked at the gray plain mourning who was also relieved.

The nerves that had been tense for a long time were finally able to relax a little and digest and absorb all the accumulated negative emotions.
