As she narrated, He Chuan gradually understood what Lin Ya meant by the three strategies.
The first two were easy to understand. While the awakened were in charge of the attack, they would also develop magic cannons as defensive tools to assist in the fight against the beast tide.
The last one was a little more complicated. To put it simply, the beast tide didn't come all at once. Instead, it was divided into many waves. The timing was uncertain, and the quantity was uncertain.
Since it was such an invasion pattern, they could accumulate resources in the battle as the defenders.
For example, they could sell beast meat to Freedom City in exchange for gold coins, and then buy military supplies and even defensive weapons!
As long as they could do that, it would become easier and easier to defend in the future.
