Zhou Xuan then said to Duan Qinglan, "This tattoo, you can buy it, but the price..."
"Young Master, just name your price," Duan Qinglan said.
"A lump sum of cash, plus... a sacrifice," Zhou Xuan stated. "This tattoo is not like the Buddha's head; without a sacrifice, it is incomplete."
Inside the Totem Hall, Zhou Xuan saw after the Blood Tree finished bestowing the Heavenly Official Blessing on the baby's back, the baby extracted its heart and gave it to the Blood Tree, then the Heavenly Official in the tattoo opened its eyes.
That was the process of the sacrifice.
At this moment, the "Heavenly Official Blessing" performed by Zhou Xuan hadn't opened its eyes, naturally because no sacrifice was offered.
Thus, a one-incense Blood Map only requires a sacrifice after the completion of the tattoo, to be nurtured at home or in the shop,
But for a two-incense soul map, without a sacrifice, the tattoo is considered unfinished, just a half-completed product.
