"Tunnel warfare, hey, tunnel warfare, ambushing countless hidden soldiers..."
Gao Guang couldn't help but start singing. His voice echoed through everyone's headset, and finally, Francisco couldn't hold back and asked, "What song is that? It's quite catchy."
"It's the song of tunnel warfare."
Gao Guang had to stop humming and explained to Francisco.
Upon hearing Gao Guang's response, Shalov became even more curious and couldn't help but say, "The song of tunnel warfare? Have you specifically studied tunnel warfare?"
"Yes, specifically studied it. I've even deeply learned about it, so you all better listen to me."
Gao Guang responded without a hint of humility and then pointed at the entrance, saying, "First fire two rounds of Cloud Burst Bombs in there, then assess the situation."
