Qin San Lang's birthday is during the peak of June's Big Summer; he is still three months shy of fifteen years old and totally inexperienced concerning certain matters. Upon hearing Gu Jinli's plan, he couldn't help but blush deeply.
Qin San Lang quickly collected himself, cleared his throat, looked up at Gu Jinli and said, "Your plan is good, it not only teaches Lu Laosan a lesson and serves revenge for our families, but also cripples one of the Lu Family's arms. It's an excellent strategy."
However...
"Wait for a moment, I'll get something for you." Qin San Lang said, and hurried back home. Shortly afterward, he returned and handed a piece of yellow paper to Gu Jinli: "This is a map of the Lu Mansion, take a good look and remember the positions of the rooms noted here."
This map depicted all the rooms and corridors of Lu Mansion, with small characters detailing the arrangement clearly—visible and instantly understandable at a glance.
