Turns out that two years make a lot of difference for those at the first steps in the Laws.
As Krune thought before, thanks to the Elemental Meridians that greatly increase the control over the elements, Tiane was finally able to comprehend one after her breakthrough into the Divine Soul Realm. As a Demon Crow, it went without saying that her first one was a Wind Sub-Law, and it was the Essence of Wind on top of that.
As mentioned before, since Tiane was able to comprehend a Law, it means that the World of Laws also opened for her. With that being the case, Tiane quickly used this opportunity to learn another two, Lightning and Fire. After the last two years and something, Tiane had brought her Wind Essence to the intermediate level and comprehend the Breeze Sub-Law at the Initial Stage. The Fire and Lightning ones were still in the initial stage, and she only learned one of each. Heat for Fire and Current for Lightning.
