Time passed quickly. In the blink of an eye, more than thirty days had gone by. The Ink Storm outside the spell formation began to show signs of weakening, while Xiao Hua's Soul Stab technique made tremendous progress! Especially after using it for the first time, Xiao Hua combined it with practical application and gained even more insights.
Another twenty days passed, and the Ink Storm outside the spell formation finally subsided. No more Ink Sand seeped in through the flaws in the formation.
