Farhadi followed Lani's advice and sent most of his troops to the military base for intimidation. As long as they trapped Ye Fan, preventing Kasam from escaping the military base, forcing Kasam to surrender would just be a matter of time. Once the situation is set, there would be no major worries. To deal with Ye Fan and Kasam, he must take strong measures and cannot relax for a moment.
By doing so, Farhadi's forces around him became vulnerable, which was the most obvious disadvantage.
However, it was necessary to do this. If Ye Fan and Kasam conspired a counterattack and mobilized forces for support, it would be disastrous. The priority is to ensure Kasam doesn't have time to wait for reinforcements.
Capturing Kasam is an urgent matter, and Farhadi deeply understands this.
The capital of Ba Country, symbolizing authority, had its communication equipment destroyed, as instructed by Farhadi to insiders before the attack. This gave him significant advantages.
