Zhuang Liu took out an exquisite velvet box. "Rourou, congratulations on winning the first place in the National Physics Competition. This is a gift for you."
Tan Rou was very surprised when she saw the gift. "Why are you giving me a gift again? Didn't I tell you that it was a simple test? There's no need to celebrate it."
Zhuang Liu didn't think so. No matter how small Tan Rou's matter was, it was still a big deal. "Rourou, I know you don't want to celebrate, so I didn't prepare a precious gift for you. This is a small gadget that I personally designed and made. I think that it would be something useful for you."
Tan Rou took the box over. Inside was a metal capsule the size of a pinky. It looked very delicate.
"Is this a Swiss Army knife?" Tan Rou took out the metal capsule and looked at it several times. "It's quite light."
