After Lady Illo, now Empress Illo, told Karsha about the unique ability of the Blue Venom, Karsha, with the help of the system, figured out ways to best utilize it to help June's mother. Inside his Divine Alchemist memories are various pills that can wake June's mother without the poison instantly killing her. One pill has the unique effect of delaying the poison for a few minutes.
Karsha has also concocted another pill that will restrict the venom for at least a month. During this time, the person poisoned can use their strength to either look for a way to neutralize the poison or say goodbye to loved ones. But in this context, Karsha wants June's mother to absorb as much spiritual energy as possible, so she will regain some of her strength for what's to come.
