Pick up Someone from Another World and Become a God

After Lu Fan swore to the old wet poster, he gained the ability to travel back and forth between the two worlds. The spiritual weapon he bought for 10 spiritual stones in another world can be sold for 1,000 spiritual stones on earth! The 100 million spiritual stones brought to the earth have tens of billions of purchasing power in other worlds! Kung Fu, elixirs, spells, mythical beasts... Buy, buy, buy! Well, we still need a bed-warming maid... Purchasing the Saint, please understand?
