"What is this?"
Geng Lele took it. Although it looked like a lighter, it wasn't one. Instead, it resembled a collection of metal strips and blocks.
Could it be a Luban Lock? I stopped playing with those things in kindergarten.
Cui Qingyuan said, "Place it on the table and knock on it twice with your knuckles."
Upon hearing this, Geng Lele promptly placed it on the table.
With a tap of her knuckles, the mundane cube flashed with light. Then, the variously sized metal strips on top twisted and turned, transforming into the shape of arms and legs.
Quickly, the cube transformed into a robot that looked a bit dopey.
It even had a small monitor on its head, across which scrolled the words "Hello."
After the greeting scrolled by, the robot began to march in place. Once done, it circled its arms in front of its chest, took a step forward with its left leg, and then raised its arms high.
Everyone was stunned.
