Letters from a Floating Life

Shen Yan inherited an old bookstore that was always losing money, and a family secret: some letters, sent to the folds of time. They come from annihilated civilizations, erased history, and unfinished lives. He can reply and slightly correct the past, but at the cost of uncontrollable "echoes" in the present world. It wasn't until he received a warning letter from his close friend three days after the funeral that he discovered that he had also been included in the "modified" list. The final recipient address of all letters is "Ding Yunzhai, Shen Yan" - this is the last backup of human civilization set by his grandfather with his life. Repair the past, or protect the present? Every letter that is opened is a vote for the world. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
