Non-mainstream Conan viewing style

Dr. Agasa hurried over, searching the crowd, and finally found Conan: "Conan, so you are here. Everyone seems to be fine."

Nitta looked around and suddenly realized something: "Where's Masaki? Where did he go?"

Dr. Agasa looked around and frowned, "So, I really didn't see him."

At this time, a low cry of surprise was heard, and everyone looked in the direction of the sound, only to see Masaki being hit by the fallen bookcase, with blood all over the floor. Dr. Agasa hurried forward to feel his pulse, then shook his head heavily: "No, he's dead."

Arata looked at the scene in shock, finding it hard to accept the fact: "How could it be? He...he..." Anger surged in his chest, he waved his hand and was about to rush towards Zaizen next to him, but was stopped in time by Dr. Agasa.

Zaizen didn't seem to care about Nitta's anger. He said calmly, "He was crushed to death by the bookshelf. What bad luck."

Nitta was held by Dr. Agasa, unable to break free, and could only stare at Zaizen angrily. Dr. Agasa looked solemn, and shook his head gently, signaling Nitta to calm down.

Conan stood aside, watching this scene, full of confusion. He turned around and saw that the emergency button of the fire alarm had been smashed and activated. He picked up a Kamen Rider model on the ground and said to himself, "It must have hit the alarm. But why did the bookshelf fall down?"

Kuno bent down in the crowd, as if looking for something. Conan walked up to him and asked curiously, "Mr. Kuno, are you looking for something?"

Kuno raised his head, his eyes flickering: "Nothing... nothing."

Conan did not investigate further, and turned his gaze to the bookcase again. He noticed a bent nail on the bookcase, and his mind moved, as if he had discovered something.

With the whistle of the police car, the police arrived at the scene. An officer was carefully recording: "The deceased's name is Masaki Naoto, 28 years old, and the cause of death is brain contusion. He must have been crushed by the bookshelf and his head hit the floor."

Zaizen looked at Masaki's body and sighed, "You hit a vital spot!"

Kuno also shook his head and sighed: "How pitiful."

Nitta cried silently, unable to accept this sudden bad news.

Officer Chiba looked around with a sharp gaze: "You must be acquaintances of the victim. But why did the bookshelf fall down?"

The shop owner nervously explained, "In order to prevent the bookshelf from falling, we usually secure the bottom. But it just so happened that the store was undergoing some modifications, and the bookshelf that fell down...the bottom fixtures were removed."

Officer Chiba nodded: "That means the bottom of the fallen bookshelf is not fixed."

The shop owner quickly apologized: "Yes. Well, I'm really sorry."

However, Ayumi raised a question: "But this bookshelf looks very heavy, how could it fall down so easily?"

Mitsuhiko also agreed: "I don't think it's that simple. Was it pushed down by someone?"

Yuan Tai's eyes widened, as if he had suddenly realized something: "Yes! Someone must have pushed him down!"

Zaizen tried hard to convince everyone present that it was just an accident: "No, the bookshelf fell down by itself. Many people saw it. It shouldn't have been pushed down. After all, the bookshelf is so old and has so many heavy things on it. It was an accident, an accident."

The shop owner nodded repeatedly, his face full of apology: "I'm very sorry, we didn't expect something like this to happen."

Conan squatted on the ground and observed carefully. Suddenly he uttered a puzzled sound: "Ah hehe!"

Officer Chiba heard the voice, bent down and asked, "What's wrong, Conan?"

Conan pointed at the bent nails on the fallen bookshelf and said, "Look at this..."

Officer Chiba looked in the direction of Conan's finger and saw obvious friction marks on the nail, and it looked very new.

"It looks like traces of friction." Officer Chiba said thoughtfully.

Conan nodded: "And it's still brand new."

Seeing Conan questioning, Zaizen was a little impatient: "He bumped into it when he fell down, it was an accident, an accident! This must be an accident. Don't interrupt, kid."
