My Supermarket Saves the Past

Chen Yang's small supermarket is on the verge of bankruptcy. He discovers a magical wall connecting to an ancient disaster-stricken area. He sends modern goods, receiving ancient treasures. The supermarket revives. Crises in the ancient world (plague, locusts, Beiman army) require his modern supplies. One wall, one small supermarket, and one young man bind the fates of two different timelines.
