No plan, however meticulous, can surpass the burst of luck.
You Zixing's current situation could be summed up as the dialectical relationship between chance and inevitability.
The Sanitation Workers had been constantly monitoring Gao Yuan's movements, knowing his location all too well. Now they had dispatched a helicopter to reach Gao Yuan's side as quickly as possible, intending to bring him back.
As for You Zixing, all he could do was search aimlessly in the sky, hoping for the emergence of the enemy to reveal Gao Yuan's precise position.
Chance was You Zixing needing the enemy to appear precisely when they did; their meeting brimmed with happenstance in timing.
But behind this chance lay inevitability, shaping and restraining it.
The Sanitation Workers were bound to find Gao Yuan and would certainly send someone. You Zixing just needed to wait, so his encounter with the enemy's Black Hawk helicopter in the sky was inevitable.
