Then... he accidentally obtained a legendary class?

While former teaches him the arts of craft, the latter teaches him the mysticism of cultivation, granting him two paths to tread in this life.

As soon as Lu Xuan woke up, he became an ordinary spiritual planter in Sanxiufang City, guarding a one-acre three-point spiritual field, and living in the world of practice.

Harvest a sword grass and get a sword pill.

Harvest a Xuan Chong vine and get a share of Yin Xingsha.

Harvest a Youquan flower and get a piece of Zhiyan Pill Recipe.

…

From then on, he guarded his spiritual field peacefully, and sat and watched the world of practice turbulent and vicissitudes.
