Conan: The Mechanic

"Lead ink?" Hoshino Kaede asked in surprise. "How did you know for sure?"

"The shape of this tattoo is not perfect," Gregory rolled up his sleeves again. "So it definitely wasn't made with a professional tattoo stencil. And with just a little look you can see that the upper outline of the heart is not actually a continuous line, but a name of a shop - a shop that was very famous about 30 years ago. The reason why they are cheap is because they use cheap homemade ink, which contains far more than normal doses of lead. While this heavy metal is by no means the culprit of epilepsy, it does represent some The thing - if you're going to send him for an MRI, you're going to be doing both damage to public property and manslaughter."

MRI is essentially an electromagnet with amazing power. If a person with heavy metal components is sent in, the ghost knows what will happen.

"Considering that his eyes can't see, and the scopolamine patch that Hoshino re-applied has effectively relieved the frequency of seizures, it should be a problem with the central optic nerve." Gregory waved his cane in his hand. a circle. "Measure his brain waves to see if there are any signal problems that cannot be detected by CT. In addition, Hoshino, take the little guy to Mrs. Nagano and ask her to take you to his house for a search. There is no place where Mr. Nagano often touches, but Mrs. does not go much. The little guy is responsible for finding any hidden treasure trove, and you are responsible for checking whether there is any problem."

At this moment, someone knocked on the door that was blocked by the curtain. "Mr. Asker?"

"This voice is..." Gregory said after thinking for a moment. "What was the toxicology screening result?"

"The tests for common poisonous ingredients, animals and plants are negative," he replied after a pause outside the door. "And the tests for common poisons are also negative."

"Common poisons?" Gregory looked at Hoshino Kaede after being stunned for a moment.

"I didn't ask for it." Hoshino Kaede was also stunned, and quickly shook his head.

Gregory frowned, then walked to the door, opened the specially-made curtain there, and asked the people outside through the door. "Who added the common poison test?"

"Ah?" Qianyu could feel the bewilderment of outsiders just by listening to the sound. "It's a boy with glasses. He said that Mr. Hoshino wants us to additionally test for common clinical poisons."

"Conan?" Chiyu and Hoshino Kaede both realized who he was talking about at the same time.

"Let's go to Mrs. Nagano immediately," Hoshino Kaede said. "By the way, I'll put on an extra pair of gloves for anyone I might meet."

……

The entrance of Nagano House.

"Where are you going?" He asked when Hoshino Kaede, who was standing behind Mrs. Nagano who was opening the door, noticed that Chiba seemed to be leaving.

"Just in case," Qian Yu said. "If nothing else, we will meet in the house where Mr. Nagano was found."

Chiba came to the window of the room where Mr. Nagano was found - just like when they first found Mr. Nagano, the window was wide open.

Chiba's "what if" is that if someone happens to do something at Mr. Nagano's house, Chiba can block him from here and won't let him run away.

The common poison investigation requested by Conan reminded Chiba that Mr. Nagano's condition may not be a natural disaster, but a man-made one.

And the three disciples of Hiroji Nagano might have committed this crime. If Nagano Hiroshi used the toilet while he was in his room and climbed over from the window, it is entirely possible that Nagano Hiroshi was plotting against Nagano without anyone noticing. All these phenomena are possible as long as he hits the head in the back of Nagano Hiroshi and causes brain damage.

However, this theory has the following problems.

1. Qianyu does not know if the visual area and the area that causes epilepsy are together, and whether it is possible to be hit by an external blow.

2. Nagano Hiroshi didn't even have blood left, and there was no obvious traumatic symptoms. In this case, is it possible to attack enough to damage the brain.

3. Where can I get this kind of blow tool that hit Nagano Hiroshi, and where can I throw it away?

Chiyu stretched the non-marking umbrella through the window to use it as a hook, and then this laborious lever pulled herself from the window to the window sill, then took off her shoes and landed lightly on the floor.

There is no furniture in an abnormal position, it does not look like it has been rearranged, and there is no blood on the ground.

It seems that the possibility of a planned murder has almost been ruled out-if it is a planned murder, an unavoidable question is how the murderer intends to kill Hiroji Nagano.

Option A: If it is hit with a weapon, it is almost impossible for the murderer not to bleed - but the floor is very clean, only a very small amount of dust remains, and it does not look like it has been cleaned. If the murderer strikes with a force that is impossible to bleed~www.readwn.com~, it is very likely that there is no way to kill Nagano Hiroji as it is now. So what is his purpose?

Option B: If it was an unarmed attack, the murderer could not even guarantee that he would be able to deprive Nagano Hiroshi of his ability to call for help and resist with one attack. As long as Nagano Hiroshi shouted, the attacker's plan completely failed.

"Is the window here not closed?" Hoshino Kaede walked in from the door, holding a camera in his hand.

"No problem," Qianyu nodded. "Are you going to take pictures of the scene here?"

"Yes," Hoshino Kaede nodded. "You put on the gloves first, and then open everything that can be opened, and I will shoot slowly."

"Okay," Qianyu nodded, and walked to the nearest cabinet—then he was startled by the sudden movement on the cabinet. If it wasn't for the auxiliary unit that brought him back to his senses in time, he would definitely shout "!!!"

The cat he had seen before lay lazily in front of the still full food bowl, staring lazily at him.

"Heartless foodie." Qian Yu glanced at the cat and opened the cabinet door after confirming that it had no intention of attacking him.

……

When Chiba and Hoshino Kaede finished the examination and were about to return to the hospital with Mrs. Nagano, the sky was already a little dark, and every household had turned on the lights, and the orange light almost compensated for the sun's grace.

"No clue at all..." Qian Yu said with a frown. "And I thought I could meet Conan here."

"The key now is," Hoshino Kaede also frowned. "What's wrong with the patient?"

Behind them, the cat was still lying in front of the small food bowl full of food on the cabinet, watching them go lazily.
