"The toughness of most metal materials is affected by temperature. This toughness is also called impact absorption energy. Take gold and iron as examples. Gold is soft, so its impact absorption energy is low and it can withstand less external force."
"Compared to gold, iron is harder, less likely to deform, has a higher impact absorption capacity, and can withstand greater external forces..."
"I see!!!"
Conan suddenly realized what Makoto Sakaki meant:
"When the external temperature drops, the impact absorption energy of many steels will drop rapidly, and the material will change from a ductile state to a brittle state..."
“It breaks very easily!”
"That's right."
Sakaki Makoto smiled:
"This phenomenon is called low-temperature brittleness, and even some well-built bridges have collapsed in the winter."
"It's even easier to kill a person who often works at heights. All you need to do is soak the lock on his body in liquid nitrogen in advance..."
"After a while, the lock becomes so fragile that it can't even withstand a blow from a hammer."
"Just imagine, if at this moment, the person tied to the safety rope falls from a height, what will happen to the buckle that has become extremely fragile?"
“Fuck…”
Takagi Wataru exclaimed:
"Isn't that a death sentence?!"
"So Captain Haneda is dead."
“........”
Everyone looked at Nishijo whose expression changed slightly.
“Hmph…Hmph!”
Saijo said in an unnatural tone:
"This is just your imagination!"
"When I climbed onto the diving platform, Xiao Qian saw clearly that I didn't have anything in my hands!"
"Besides, the temperature of metal frozen by liquid nitrogen is extremely low. If you touch it easily, you will definitely get hurt!"
