But it was said that Kongming had taken the "Taiyi Divine Calculation" taught by Ghost Valley to calculate, and had determined that a thick fog would cover the river, which was the perfect time to "borrow" arrows from Cao's Naval Camp.

Enlightenment Dao had arrived at Eastern Rivers early and watched everything clearly. However, he knew about the famous story of "Zhuge Liang borrowing arrows with straw boats" from later generations.
