"That's great!!" Upon hearing Hua Biao's translation, Old Lin excitedly slapped his thigh, making a "pa" sound.
It's no wonder Old Lin was so excited. The dots of firelight on the rooftop meant not only the signal for the operation to begin but also the safety of his closest people.
"Send a message back to Old Xu and let him know we've understood, and we'll take action soon!" Tang Xiaoquan immediately instructed Hua Biao. He knew that every minute, every second at this moment was extremely precious, with Old Xu taking the risk to climb to the rooftop. They needed to reply back quickly so he could return indoors to prevent any accidents.
"Okay! I'll send it now!"
Hua Biao nodded, took out the infrared flashlight prepared in advance.
This flashlight, available in regular stores, is characterized by its long range and narrow beam.
Even if used in the middle of the night, it wouldn't be detected by zombies.
Using Morse code rules, Hua Biao repeatedly flicked the flashlight switch.
