Low-grade Dao Origin, medium-grade Dao Origin, high-grade Dao Origin, and top-grade Dao Origin were actually exclusive.
This was because low-grade Dao Origin was the currency used to transact between Law Heavenly Venerates. Moreover, low-grade Dao Origin could only help Law Heavenly Venerates cultivate.
Medium-grade Dao Origin was the currency used to transact between Rule Heavenly Venerates. Similarly, it could only help Rule Heavenly Venerates cultivate.
The cycle repeated.
High-grade and top-grade Dao Origin were the currencies used by the Eternal Supreme Venerates in transactions. They could help the Eternal Supreme Venerates cultivate and increase their cultivation levels.
Therefore, there was not much comparison between the four.
They could be exchanged for in some super-large Upper World Chamber of Commerce.
Normally speaking, a medium-grade Dao Origin was equivalent to 100,000 low-grade Dao Origin.
