The students throughout the room fell silent, their eyes following the silver-white Space Window-Cleaning Bug from left to right, then right to left.
Someone put their own window-cleaning bug on the window. It crawled along sluggishly, clumsy as though it had run out of power, completely different in style.
"We're doomed! Song He bought the genuine article! All our window-cleaning bugs are knockoffs!" someone joked.
The students immediately burst into laughter. Then, not knowing who had started it, everyone excitedly applauded!
Optimizing a window-cleaning bug required computer speed testing, but the extent of Song He's bug's evolution was obvious even to the naked eye!
It had practically become an entirely different species!
Song He looked up at the window-cleaning bug at the top of the giant screen, then glanced at Professor Wang with an embarrassed expression.
"Professor, it climbed too high. I can't reach it without a ladder."
"We can't get the window-cleaning bug down, so there's no way to test its speed either..."
Professor Wang raised his head and stared at the little silver-white creature for a long while. "Look at its path. It's wiping the giant screen from left to right, moving downward one centimeter at a time."
Song He nodded. "So we just wait for it to come down?"
"That's right. It'll come down." Wang Taichu smiled. "Explain the program first. By the time you're done, it'll have crawled down. Then you can catch it and test its speed."
Song He had no choice but to open the computer and display the rewritten program on the giant screen.
A vast and magnificent point cloud, dazzling in every color, drifted across a pitch-black background. It looked just like a nebula in outer space!
Within the enormous point cloud, bright-yellow streams of data surged along, occasionally converging at several
