The note read:
"Hello, Academician Han!
"Inside this USB drive is data for a 1-nanometer precision lithography machine. The password is 148257. I hope it can contribute to the development of our country."
The signature read: An anonymous patriotic citizen.
After writing the note, Bai Xi placed it and the USB drive at Han Yuanshan's door and knocked.
"Who is it?" Huang Meijuan opened the door and looked around. Just as she was wondering why no one was there, she spotted a silver USB drive and a piece of paper on the ground. She glanced down the hallway, but it was completely empty. She picked up the items and closed the door.
"Dear, who was it?" Han Yuanshan asked, walking out of the kitchen.
Huang Meijuan shook her head and waved the items in her hand. "I don't know. There was only this silver USB drive and this piece of paper."
Looking confused, Han Yuanshan took the items from Grandma Han. He read the contents of the paper and furrowed his brows.
