The mid-grade immortal crystals used for simplification naturally came from Wei Daozhen.
As an Early Earth God Realm expert, Wei Daozhen had accumulated quite a few mid-grade immortal crystals and mid-grade Great Dao Stones. They were more than enough for simplification.
Mid-grade immortal crystals and mid-grade Great Dao Stones were indispensable to Earth God Realm cultivation. These were the foundations. Reaching the pinnacle of the Early Earth God Realm required 1,296 mid-grade Great Dao Stones.
The number 1,296 carried a special significance. It applied to Realm Lord cultivation, and still held true in the Earth God Realm.
If Chen Fei wanted to cultivate both essence power and physique, he would need plenty of mid-grade Great Dao Stones. Wei Daozhen had some mid-grade immortal crystals, but far fewer mid-grade Great Dao Stones-only 237.
Back in the Realm Lord Realm, Chen Fei could condense low-grade Great Dao Stones himself. But in the Earth God Realm, he had never heard of anyone capable of condensing mid-grade Great Dao Stones on their own.
Low-grade Great Dao Stones were produced by deposits resembling mineral veins. But for mid-grade Great Dao Stones, there were no ready-made veins to mine.
The only way was to enter secret realms and kill the Eleventh Order monsters within. Mid-grade Great Dao Stones formed inside those monsters.
The Cold Mountain Domain controlled an Eleventh Order secret realm. Chen Fei had even entered it, and knew how many Eleventh Order monsters were inside. All of them were resources-cultivation resources crucial to the Earth God Realm.
There were also Eleventh Order heavenly materials and earthly treasures within the secret realm. Refining them could produce effects similar to mid-grade Great Dao Stones.
But these were merely the foundations. How many rule characteristics one could master, and whether one could obtain middle-grade Eleventh Order status
