Because the process of absorbing the Spiritual Qi is like breathing to the spiritual plant, it would naturally lose its grip over the soil while doing so. And since Qin Lan's hands were holding and feeding it with Spiritual Qi continuously, this trick worked like magic to fool the spiritual plant.
The recently taken-out Oxhorn Root was as big as a human's thigh when it was forced out from the soil. But it turned into the size of a lower arm as soon as it left the earth. This happened because the medicinal herb is no longer receiving any nutrients from the ground to keep growing.
With one plant were done, Qin Lan continued with the second Oxhorn Root. Eight plants were harvested in the row of ten spiritual plants Qin Lan was assigned to, leaving only two on the field. From his rough estimation, they should be matured in the next two days.
Turning his head and looking at the other helpers, Qin Lan was shocked that they were currently at the fifth or sixth plants.
