Lin Fan and Feng Zhixiang had interacted many times.
He had a good impression of this old man who worked hard for the country's scientific and technological development.
Therefore, without much hesitation, he pressed the answer button.
"Professor Lin, you submitted Principles and Future of Gaming Helmets to Nature?"
Feng Zhixiang's urgent voice sounded as soon as the call was connected.
"Yeah," Lin Fan said slowly.
"Gaming helmets… can they really be made?" Feng Zhixiang asked nervously.
Lin Fan said, "Sure, I've been playing with one for a few days."
"Playing… How many days have you been playing?" Feng Zhixiang stuttered.
Then, he asked in disbelief, "You mean…"
Lin Fan said, "Yes, I've already invented it."
"Good, good, haha! That's great!" Feng Zhixiang laughed happily. "Professor Lin, where are you? I'll be right there!"
