Don't Have Money to Practice Immortality? I Just Want to Make Money in Both Worlds!

Li Yi traveled through time and discovered that this world not only has advanced technology, but also has immortals who fly to the sky and live forever. It's just that this world has already entered the era of capital. Everything in the world, including spiritual energy, has been marked with a price. Without money, you can't even absorb spiritual energy, let alone cultivate immortality? Fortunately, Li Yi awakened the two-realm trading system. Not only can he travel to another traditional world of immortality, he can also convert the items traded between the two sides into points. So Li Yi started as a Taoist master from the two realms and began his own path to immortality. Can't become an immortal without money? I just want to make money in both worlds!
