When Su Xinyan heard this, she didn't comfort Fang Zhou as usual. Instead, she sighed along with him. "Yes, I've had my share of struggles with this too. Especially since you're still in the Apprentice Stage, the only type of Heavenly and Earthly Treasure you can absorb is Nether Amber."
"When you reach the Black Iron Tier, to truly unlock your potential and enhance your aptitude, you will need to absorb a potion refined from two types of Undead Attribute Heavenly and Earthly Treasures: the Bone-Eroding Blood Spring and the Breath of Decay. I also went through immense hardship back then and only managed to obtain the second raw material by a stroke of luck in the final stage, just before breaking through my bottleneck to advance to Bronze. Only then could I refine the required potion."
