Going Up (6)

Feng Bujue paused for several seconds before announcing, "The distance between the two pillars and the object is exactly nine meters."

When he uttered the words 'meters', it was soon followed up with "Run!"

As he finished, Autumn Zither started to move, and they heard the building crumbling behind them. This proved that at that moment, Autumn Zither's 'understanding' had activated SCP-233. The crumbling sound did not affect Autumn Zither. He ran like crazy until he reached his teammates. Then, he turned around to see what had happened.

SCP-233 only needed 0.23 seconds to destroy physical objects, and that process was soundless. Therefore, when the crumbling began, the destruction process had already finished. What Autumn Zither heard was the aftermath, the sound of the building materials falling from the ceiling.
