The plan proposed by the military can only be described as insane.
Even with his frequent wild imagination as a web novelist, often jesting that above his neck is a black hole, Chen Xin was shocked by the military's fantastical proposal.
The military's plan is less of an attack plan and more of a construction plan.
Speaking of underground warfare, this kind of tactic was not unfamiliar to the Flame Country's military back in the day, and they also had some experience in clearing out enemies in tunnels.
However, these experiences have certain limitations.
After all, whether it's using smoke and fire, flooding tunnels to force enemies out, or using ground-penetrating bombs to blow up hills and unload mountains, they are somewhat effective against small-scale tunnels, but are utterly useless against large-scale underground caverns, especially ones that are excavated several hundreds or thousands of meters deep.
