The Back Door of My House Leads to Another World

Lin Feng, an ordinary young man who was frustrated in life, unexpectedly discovered that the back door of his old house, which had been in disrepair for a long time, could randomly lead to another world. Starting from the initial timid exchange of a bag of salt for a piece of spiritual stone, he relied on the common sense, materials and wisdom of the modern world to travel between other worlds, and step by step established a huge business empire across dimensions. At the same time, he also explored his own cultivation path through endless adventures and transactions, and finally grew from a mortal to a supreme being that even the supreme beings of other worlds need to look up to.
