'TING'
Suddenly an idea hit his mind.
Before going to the coffee house, Feng Jianyu went straight to a book shop and purchased a book on hacking.
After reaching the coffee house, he settled down and ordered his coffee. He opened his laptop and started typing something on it by following instructions from the book. Alice came there and put his coffee on the table as usual, "Your coffee sir, please have it while it's still hot". She smiled and left.
For almost 3 hours he sat there and worked on the laptop. From time to time he would curse silently, and tap on laptop keys roughly. Alice saw this and frowned, but did not approach him.
Feeling annoyed, he got up and left the place.
While cleaning the table, Alice found a book kept on the chair. Taking the book in his hands she frowned, "Hackers hacking? I think that strange man left it behind. I will give him back tomorrow".
