The harvest that came most intuitively to mind was his numerous sariras.
Back when the Great Thunderclap Temple was destroyed, a large number of sariras fell into the hands of the Great Zhou Empire while several sariras got dispersed to other areas, and the Golden Cicada Master had collected a considerable portion of those.
The Golden Cicada Master naturally could not use those sariras as ingredients to craft treasures with ease like Liang Pan or Zhu Hongwu, but the sariras in his possession were still properly preserved. If Lin Feng paid closer attention, he might even have sensed the incense remnants.
This time round however, the Golden Cicada Master only deployed them to establish his battle formations but Lin Feng rounded all of them up and collected everything that he had.
