After a few days of cultivating in the Jin Xiu Peak Cave House, Lin Yi harvested approximately three acres of mature spiritual herbs before planting some more. These herbs were also ingredients for the Foundation Building Pill.
His high-level farming spells, Rainfall Technique, and Spring Nourishing Technique, have all reached the Great Perfect Level, making them more than capable of handling not only intermediate pills made with spiritual herbs but also high-order spiritual herbs.
Sister Han Ling Shu, during the construction of this cave house at Jin Xiu Peak, purposely brought in spiritual spring water from the waterfall for the eight acres of average medicine fields, allowing spiritual herbs to be irrigated with spiritual spring water.
However, farming spells need to be used to add nutrients, though not as frequently as before. Even if the herbs are left unattended for several days, their growth will not be affected.
