Deep in the dense forests of Cangwu Province, Major Hideo Kuroki of the Special High School Division sent a top-secret telegram to the Fuso Military Headquarters: Three days later, we will attack our 103rd Division headquarters at night.

Shen Yezhou didn't answer.
He turned the message sideways and copied the number string in the blank space with a pencil:
