What is the result of borrowing arrows from grass boats?

Borrowing arrows from straw boats is a famous bridge in Battle of Red Cliffs of the Three Kingdoms. Borrowing arrows was deliberately put forward by Zhou Yu (limited to 100 thousand arrows in ten days). The witty Zhuge Liang saw through it at a glance and said calmly that it only took three days. Later, Zhuge Liang used the foggy days and Cao Cao's suspicious character to lure the enemy with several straw boats, and finally borrowed 100 thousand arrows, which made a great difference.
