Zhu Chunlai was about to start filming with his camera, but Zhao Yi hurriedly stood in front of the lens and apologized, saying, "Classified!"
Xu Chao came out.
He had been working the whole time, letting the robot make coffee for him. When he heard the door open and knew that Zhao Yi was back, he thought nothing of it. But it seemed the commotion outside was not just from one person.
"Zhao Yi, who are these?" Xu Chao pointed at Wu Wensheng and Zhu Chunlai.
"They are an interview crew from CCTV."
Zhao Yi explained briefly, and introduced everyone. When Wu Wensheng heard that Xu Chao was a doctoral student working with Zhao Yi on a project, he had a hard time wrapping his head around it.
PhD student?
High schooler?
Then Wu Wensheng recalled Zhao Yi cracking the Collatz Theorem and his connection to computing academia and research, and he figured that there was no reason to be surprised about anything.
They only stayed for a short while before leaving.
