The Golden Winged Eagle soared high in the sky, presenting itself to the naked eye as nothing but a small, inconspicuous black dot. Yet, from its eagle-like vision, it could view the minutest movements of a piece of grass or a grain of sand precisely, with a range far greater than that of a cultivator's divine sense.
Under its protection, several people proceeded swiftly.
Of course, it wasn't necessary for them to search every inch of the river bank meticulously, since the growth of the Immortal Ascending Grass had certain characteristics. For instance, some spirit plants would not coexist with others, they instead absorb all the spiritual energy from their surrounding area for their own growth.
However, Immortal Ascending Grass could coexist with all plants, and they were usually found amongst lush greenery.
Therefore, they didn't need to pay attention to areas with sparse plants. All they had to do was closely examine every dense forest and grassland they passed through.
