Lin Nianchuan bought an old house from the Republic of China in an old alley in Jiangcheng. When he was renovating and smashing the walls, he dug out a rusty iron box from the cracks in the bricks.
Inside were 27 never-sent letters and 20 yellowed single photos, all belonging to young soldiers of the Sichuan Army. On the back of one of the blank cards, only the word "Lin" was engraved with force.
That was Lin Zhiyuan, the fourth grandfather whom grandma had regretted all her life. He left home at the age of fourteen to go to Jiangcheng to fight, and he didn't even leave a photo.
When the fingertips touched the letter, white mist suddenly rose, and the outside turned into the war-torn Jiangcheng alley in 1938!
She obtained a time and space anchor: she can travel once every 7 days, staying no more than 12 hours at a time, and her range of activities is limited to a kilometer radius of the old house.
She carried a first-aid kit to bandage the bleeding, controlled a drone to drop antibiotics and life-saving drugs at risk of death, and used Polaroid to take the first and last color photo of the scarred teenagers with their neat faces.
Until the young soldier covered in blood timidly told her: "Sister, my name is Lin Zhiyuan, and I am fourteen this year."
Lin Nianchuan's eyes turned red before he realized that the 27 final letters in the cracks in the wall were exactly the destinations that the lively young people in front of him were about to write down.
The wheel of history cannot be reversed, and they are destined to die at dawn;
But across 86 years of time and space, she will try her best——
Send them home letters that are more than half a century late, and let them take a look at the screen of their mobile phone before they die generously, and see the prosperous China and the lights of thousands of families that they exchanged for their spines.
