The both of them arrived at the area the robots had encircled.
The robots moved out of the way.
Zi Yi asked, "Where's the item that was detected?"
One of the robots pointed to the ground. "Master, one meter underground."
Zi Yi looked at the tiled ground, then at the masked man. "Do we dig?"
The masked man took out a dagger, squatted down, and stuck his dagger into the cracks. After he observed for a while, he asked, "Can your robots detect if there is anything dangerous underground?"
Zi Yi asked her robots, and one of them replied that there were no dangerous elements.
Once again, she turned towards the masked man, and she received a nod from him.
Zi Yi ordered one of the robots, "Dig up here. Be careful not to damage the item inside."
"Yes, Master."
The robot's arm soon transformed into a drill, which drilled into the ground. Shortly after, it turned into a shovel as it rapidly dug out the soil below.
