In military strategy, the preparation for airbase attack varies depending on different factors such as the weather and proper timing. According to the information provided, there are specific days and seasons that are considered ideal for making attacks with fire. The proper season is when the weather is very dry, and the special days are when the moon is in the constellations of the Sieve, the Wall, the Wing, or the Cross-bar.

If the flames reach their peak, an attack can be launched if feasible, otherwise, the troops should hold their position.
