The city had already been inundated. The monsters dispatched by Xiao Bai and the assassins couldn't enter through the secret tunnels.
Chen Jiu commented, "The city is flooded, we can't avail the secret tunnels now."
"So what if it's inundated? I'd say, we'll see how long this rabble can hold out," Xiao Bai declared.
Chen Jiu retorted, "Although the flooded city might seem advantageous for us, it also hampers our siege efforts. After all, the city is full of water. If they guard their airspace and fortifications, we'll be powerless against them."
"Ha-ha, do you think they can last for a few days? Without enough water, they'll have to drink poison water. The flood in the city will also contaminate their food with poison and then they won't have any food to eat."
"That's true."
"Out here, we have inexhaustible food and drink. Can they endure for a few days?"
"Quite right, we can starve them out."
