"What's going on?" The old man in a white coat frowned and looked at the girl in front of him. "Haven have you learned the derivation of the whole process before?"

"I know, but..." The girl's face showed a difficult look. "I forgot..."

"What's going on?" The old man frowned - the girl's learning ability is the top among her peers and even the previous grade, but she forgot about the content of a not-so-deep book she had just read some time ago.

"I don't know..." The girl's face became more confused. "I have no impression of the content of this book."

"I have no impression?" the old man frowned.

"I don't remember reading this book." The girl shook her head.

"..." The old man looked at the girl's expression in silence and sighed. "I understand. You should hurry up and read this book, there is not much time left."

...

[Have I really read this book?] Looking at the book in my hand, the girl was a little confused - the contents in it were not particularly difficult, but she really had no impression of part of the book.

This book is mainly about chemistry, and articles like this usually describe a new idea or a new configuration of a certain compound - but she has no impression of these things that she can't forget after reading them once.

Forget it, read it slowly. If you really forgot the whole book, then read it again and remember all the parts you should remember again.

Haibara Ai woke up from his dream and found that he did not wake up naturally, but was awakened by Qianyu. "?"

"Here you." Qianyu's expression was quite serious, and he walked around the back of Haibara's neck and pointed ahead. "He is walking over there."

Haibara Ai immediately woke up and immediately caught the person Qianyu was watching.

This is a pretty burly man in a grey turtleneck trench coat and a grey hat pressing on medium length matte black hair.

Just when some people had noticed this man's strange dress, he had already arrived behind Kitaro Izumo who was smoking a cigar and staring out of the window with stunning eyes on the wall of the tunnel under the dim tunnel lights. The two of them could already see the side of the man, and they saw that he was wearing a pair of sunglasses and a mask on his face, wrapping almost all the external features.

Qianyu hugged Ai Haibara into his arms, lifted the umbrella that had been opened before to the two of them, and acted as a cover for them.

At this moment, the windbreaker began to rise and fall. The man took out a pistol from the windbreaker, and then pointed it at the strange thing, turned his head to look at the man Kitaro Izumo who had already noticed it.

Haibara Ai stared at Izumo Kitaro's body movements, while Chiao also used the auxiliary unit to lock the man's pistol to prevent potential risk of random shooting. His hand holding the traceless umbrella was ready to be fully defensive.

"!" Izumo Kitaro's eyes were wide open and was about to react, but it was too late.

"Bang!" With the flames bursting from the muzzle, Izumo Kitaro, who was still surprised, turned to halfway, and a bullet hole appeared on his head, and he slapped his head heavily on the desk.

"Why didn't Edogawa take action?" Ai Haibara looked at Kitaro Izumo who was obviously dead and asked. "Isn't he right there? Why didn't he do anything?"

"I don't know--" Qianyu raised his head slightly, intending to look at what happened to Conan, but found that the man had already pressed his hat with his hand without a gun, and then ran towards them. At the same time, Conan's voice also sounded from where Conan and Dr. Agasa were sitting. "Don't run!"

"..." Qian Yu frowned and looked at the man running towards him, holding a gun in his hand.

He can stop this man, but he can't stop this man. After all, he still has a gun in his hand. Even if he has a traceless umbrella, he will probably not be able to escape without any loss, not to mention that there is still someone next to him...

In this way, Qianyu watched the man flash past him. Immediately afterwards, Conan and Dr. Agasa also flashed past him.

"Don't you go and have a look?" Ai Haibara looked at Qianyu and asked.

"I don't think there is any need to over-stimulate the other party," Qian Yu shook his head. "Anyway, you will basically know who the murderer is after a glance. There is no need to worry about this for a while."

"I know who the murderer is?" Haibara Ai frowned.

"Yes," Qianyu nodded. "But, let's--"

At this moment, the dense gunshot suddenly rang.

"!?" A shocked expression appeared on Qianyu's face. "Hey, Haibara, didn't you say you didn't ejaculate?"

"I don't know," Haibara Ai's face was also full of confusion. "It sounds like he had all the bullets shot. Let's go and have a look?"

"Yeah." Qianyu nodded, then closed the Wuhen Umbrella, stood up from the sofa with Ai Haibara, and walked towards the carriage behind where Conan and others disappeared.

After crossing two entire cars and reaching Carriage No. 9, Chia and Ai Haibara finally saw Conan and Dr. Agasa - at this time they were standing in front of an open cabin door.

"What happened?" Qianyu asked while approaching them.

"You guys are here too," Conan didn't seem surprised by the incident. "The man seemed to have jumped out of the car."

"What!?" Qian Yu was stunned, then trotted a few steps, came to Conan, and also looked into the cabin.

This cabin is a very neat b1 cabin, and the bed does not seem to have any signs of passiveness. But at the end of the cabin, the windows have undergone large-scale damage of more than 80% of the area.

"Don't tell me he jumped off the car?" Qian Yu was stunned. "This car has a speed of at least...75 kilometers per hour, right?"

There is no training in the organization for jumping a car, but the training content is basically around 20 kilometers. It is said that an action team like Gin can complete a perfect jumping a car at a speed of 50 kilometers per hour, but... it is a bit sensational if the speed is 75. Even if the posture is standard, it will cause great damage to the body. What's more, once the posture is not perfect, the bones of the body part that lands first can almost be said to be abandoned.

"At least you can escape," Conan shrugged. "Although it is indeed dangerous, staying in the car will only be more dangerous."

"But the question is, why do you have to be here?" Qianyu spread his hands. "Is this murderer stupid? Why do you have to kill people in such a place and then play a difficult stunt like jumping a car?"
