In the post-apocalyptic world, with the assistance of the Insect Army serving under him, Lv Zhong effortlessly harvested quite a number of Light Energy Crystals. Among them, there were over a hundred of the First Order, five of the Second Order, and one of the early Third Order.
Such an amount of Light Energy Crystals would be enough to sustain the Heaven-burning Great Brightness Butterfly for three months. Moreover, they could help it grow to the early to mid-second stage, becoming an entity with power comparable to a Spirit Movement Realm Cultivator.
