This was obviously an unusual situation. How could glass on the window of such a building be so tough?
Assistant Yao thought about it and decided to use his super speed to his advantage. He wasn't very good in calculations or physics but he was aware that if his hand moved at a certain frequency, it would be able to vibrate at the same frequency as the glass window, thus allowing it to pass through the glass without breaking it.
At that moment, that seemed to be the best solution.
Hence, Assistant Yao started to vibrate his hand at a high speed and placed it on the glass window.
Since he didn't know the right frequency, he decided to just try and when it reached the right one, it would allow his hand to pass through.
After waiting for almost a minute, he suddenly felt as if the glass had become one with his hand and almost all his arm was on the other side of the window.
He didn't waste any time and unbolted the window before pulling out his arm.
