Having heard what his granddaughter said, the old man with the big smoking pipe suddenly looked up toward the west and sighed, "Those old friends, it's been many years since I've seen them."
Long Nannan didn't want to dwell on this topic since it was her grandfather's sorrow, so she changed the subject, "Grandpa, lately the enemy's attacks have been getting more fierce, and it looks like we are almost unable to hold them off. Could it be that one day, we really won't be able to stop them?"
The little old man showed no concern on his face and just chuckled, "Silly granddaughter, you must understand something. Anything that's solely defensive, no matter what it is or how impregnable it may seem, will eventually have a day when it can no longer hold out, and we must come to terms with that."
