Daoist Chu and Ziran's conversation shifted from the Outer Territories and Farlands to other matters which didn't interest Lin Mu as much, so he fully focused on his cultivation.
He had grown five of the basal elemental cores to the Immortal level and was now stumped with the Wind and Lightning cores.
'I do have a few herbs for the Wind Element, but for Lightning element I barely have a handful.' Lin Mu thought to himself.
He had hundreds of Wind Elemental Spirit herbs and about ten for Wind Elemental Immortal herbs, but he only had six Lightning Elemental Spirit herbs and two Lightning Elemental Immortal herbs. Other than the herbs, he had a few other materials that also had the two elements such as some Mountain Peak Jade that was formed under the sharp winds of a mountain peak and the lightning of a storm.
But having progressed the other cores, Lin Mu knew for sure these will be barely a drop in the ocean.
~Sigh~
