After taking enough photos to her heart's content, she sat on a swing woven from underwater vines, took out the gift box, and started to solve the password.
She had already found six password digits: 2, 7, 1, 5, 5, 2.
Lin Hanfeng stood beside her, gently pushing the swing, allowing her to sway on it.
Xia Siyuan tried combining the numbers in various ways but couldn't solve the password. "How exactly should I combine them?"
Lin Hanfeng didn't tell her, only saying, "Think for yourself, it's simple. Can't you guess these six numbers?"
"My intelligence is limited."
Lin Hanfeng still didn't tell her.
Okay then, Xia Siyuan had to continue thinking, 2, 7, 1, 5, 5, 2...
Suddenly, an idea hit her: "Is one of the combinations 521, right?"
Lin Hanfeng smiled silently, giving her a positive nod. Smart.
"Then the other three numbers, 2, 5, 7,... could it be 725?"
