Tu Xiaolan pointed at this large door and said, "This door is specifically used to test strength."
Xiao Zheng immediately looked over upon hearing this.
He saw this 'door' standing in the middle of a vast empty space, with a long runway behind it.
Xiao Zheng instantly understood the purpose of this door. He anticipated starting from that runway and then passing through the door, at which point his speed would be measured and recorded.
Sure enough, Tu Xiaolan explained the function of the door next, mirroring what Xiao Zheng had thought.
Xiao Zheng nodded promptly and then walked to the end of the runway, facing the door, and said, "I'm about to start."
Tu Xiaolan and several staff members quickly avoided the door from a distance. Evidently, the previous incident where the sandbag instrument got bombarded had left a deep impression on them, fearing that Xiao Zheng might break the door again.
