Lao Zhao's expression changed, anticipation appearing in his eyes.
Beside him, Professor Ma, sitting in a wheelchair, also flashed a sharp gleam in his eyes and leaned forward.
Xiang Xiaotong walked behind Lao Zhao. First, she pulled a plug wire from the back of his head, then switched off the Mechanical Hand's elbow joint, and finally pulled out an elbow data cable and plugged it into the computer.
A download progress bar popped up on the computer and reached the end in just half a minute!
Xiang Xiaotong walked behind Lao Zhao again and reconnected the plug wire at the back of his head.
"There might be a brief adjustment period after it's connected, but it shouldn't hurt. If you feel a sharp pain, call out and I'll turn it off." Xiang Xiaotong asked, "Are you ready?"
Lao Zhao was visibly nervous. He took a deep breath and nodded. With a "click," Xiang Xiaotong switched on his elbow joint.
Under everyone's watchful eyes, the Mechanical Hand activated. Lao Zhao stared fixedly at it, his expression suddenly changing to one of utter astonishment!
The Mechanical Hand began to move. Each finger bent rapidly, followed by a forceful clench into a fist, a flattening of the hand, and a turn of the wrist. It flexed and extended with perfect ease!
Lao Zhao sucked in a sharp breath, his expression turning both delighted and shaken!
He raised the Mechanical Hand toward the brilliant sunlight on the balcony, watching his own hand as he repeatedly stretched it out and drew it back, utterly entranced.
In the wheelchair beside him, Professor Ma pulled out his phone, raised it, and began recording Lao Zhao.
"Stop grinning like an idiot. How do you feel? Give us a few words." Professor Ma spoke in a faintly teasing tone.
