Just Trying to Make Money from the Difference Between the Two Worlds

Ning Yi can travel freely between the two worlds. In the modern world of immortality cultivation, after years of development, the spiritual energy has declined and the spiritual plant resources have been almost exhausted. The lower-level immortality cultivators can only use cheap medicines to practice. The prices of slightly older spiritual medicines are incredibly high. But whether it is drawing talismans or refining elixirs, the technology has reached its peak. The world on the other side was cultivating immortals in ancient times, with extremely rich resources of spiritual energy and spiritual plants. It was a golden age for cultivating immortals. However, both the techniques for drawing talismans and refining elixirs were extremely crude and would cause significant waste. In the modern world of immortality, one spiritual stone can buy two talismans. Here, even five spiritual stones are in short supply. "I give spiritual resources to the modern world of immortality, and technology to the ancient world of immortality, to help both worlds develop rapidly. And what you have to do is help me become an immortal!"
