"Grandpa, why are we doing this? Didn't you tell Xueer that learning these is to help others? Why don't you let others know?"
The old man stroked his granddaughter's head sadly, and showed a puzzling smile to the five-year-old child who didn't understand anything: "Haha, Xue'er made an agreement with grandpa! An agreement that cannot be known to others is a secret that only grandpa and Xue'er know. Does Xue'er understand? You must remember not to let others know!"
The young Xue'er looked at her grandfather's increasingly excited expression and nodded in confusion, making the old man sigh helplessly and hugged Xue'er's little body with a hint of endearment.
…
"No, Grandpa! Don't leave Xue'er alone~~Grandpa... Grandpa... Don't leave Xue'er! Xue'er will be very obedient! Wuwu~~Grandpa - don't leave!"
"Xue'er..." The old man raised his hand with difficulty to wipe away the tears on his granddaughter's face, but he couldn't even use any strength. "Xue'er, be good, grandpa is just going to another world. Remember you promised grandpa not to tell anyone that you will... Will..."
Xueer watched blankly as the old man passed away with a trace of reluctance, a trace of worry and a trace of resentment.
