"I have a question," Cheng Ziang said.
"Speak!" Yunji nodded.
"Have you ever used such tactics before?" Cheng Ziang asked.
"No," Yunji answered, "that passage was meant for the residents of the city to escape, not for attacking the city. It's just that this time the Dongsheng army attacked, we were well prepared, and the residents of Big South East Peace had all been evacuated. So we sealed off the tunnel to prevent the Dongsheng army from discovering it."
"Pretty self-aware," Cheng Ziang said in Chinese to Hu Daoke, it was unclear whether he was being sarcastic. Finally, he looked at Yunji and asked, "So, I suppose this thing can only be used once?"
"Yes, I hope it's the first and last time," Yunji gently nodded in confirmation, answering indifferently.
Leaving the tent, the two were on their way back when Cheng Ziang elbowed Hu Daoke and blinked, asking, "Old Hu, got any ideas?"
"What kind of ideas?" Hu Daoke was taken aback.
