Chen Fei's heart was full of surprise. He hadn't expected that the purpose of the Ding Ear was to create Rule Crystals.
If it was possible to create Rule Crystals, after Chen Fei broke through to the seventh-tier, the value might be relatively low, but for the Primordial Sword Sect, and for the entire human race, its value would be immense.
Chen Fei seriously examined the embryonic form of the Rule Crystal inside the cauldron. A moment later, Chen Fei's brows slightly furrowed as he seemed a bit too optimistic.
The Ding Ear was indeed absorbing the vital energy of heaven and earth and then creating Rule Crystals, but the speed was exaggeratedly slow.
Perhaps the original, complete bronze cauldron could create Rule Crystals very quickly, as it was an Eighth-Tier Supreme Treasure. But now, with only the Ding Ear left, both its function and capability had significantly decreased.
To say that it retained one-tenth of its original capability might still be an overestimation.
