While Hua Tuo taught Zero about surgery with different animals from fish to boars and snakes, the brunet found himself getting incredibly busy around the village. First, there was gardening to do. Cleo and Latitia worked hard to cultivate the strange herbs and medical plants that Zero wanted. He was in the middle of experimenting with their uses with Hua Tuo to see if any of them could be used to help Ruth with his sunlight allergy.
Also, the teenager had been dragged to and fro from Lovina's library to the lab's hideout. The witch wanted Zero to help her with the chaos energy balance equation. The witch was still testing the relationship between qi, chaos energy and mana. Her job was to validate Wiser's theory and give the researcher a proper measurement for the balancing point of all three energy types. On the other hand, Wiser and the lab rats were working on creating a harvester machine that could store chaos energy from the abyss and convert it into power.
