It seemed to be saying: Oh, you're here.
"How many steps has it taken?" Yang Ping quietly asked Fritz.
"Seven steps." Fritz's voice was also soft, "The best today was seven steps. That's two more than last week."
Yang Ping squatted down to look at M7 at eye level.
M7 tilted its head, then reached out a hand through the cage bars, fingers spread open.
This time, Yang Ping didn't hesitate. He extended his hand and held M7's fingers. The monkey's fingers were thinner than a human's, its palm rough and slightly cooler, but had a decent grip. It grasped Yang Ping's fingers and shook them, like a handshake, or a greeting.
Fritz watched from the side, saying nothing but with a slight smile at the corners of his mouth.
Yang Ping released his hand, stood up, and turned to Manstein.
"The paper was accepted?" he said.
Manstein nodded: "Accepted!"
"Professor," Manstein said, "this paper should be yours, it's your theory, I just conducted the experiment."
