The shop owner Lin Xu is not an ordinary person. The reason why he can hear the sound of old things is because:
He himself is a "forgotten old thing".
Many years ago, Lin Xu was a gentle and kind-hearted young man who loved to help others. He died unexpectedly while saving a stranger who fell into the water. The world remembered his kindness, but slowly forgot his name and existence.
God took pity on him and turned him into the owner of the Echo Hall, trapped in the old street for eternal reincarnation:
He has to collect 10,000 regrets from the world and make peace with the world in order to get his forgotten life back.
But hidden taboo rules
All regrets that have been resolved will reversely deprive him of his own memory.
The more people he saves, the more he forgets who he is.
When everyone feels relieved, Lin Xu will completely disappear and no one will remember him.
Purpose: All obsessions come from the unreconciled past, and healing is a gentle farewell to the past.
