Zhang Yue discovered that every ten low-quality fire seeds could be fused into one high-quality fire seed!

Although the ten-to-one ratio seemed a bit uneconomical, low-level fire seeds were of no use to someone like Zhang Yue, who pursued the ultimate.

So, Zhang Yue fused 185 ordinary fire seeds into 18 rare fire seeds.

Adding the 32 rare fire seeds he had found, he had exactly 50 rare fire seeds, which he then fused into 5 supreme fire seeds!
