Dao Sources were hard to come by. Aside from earning them through meritorious service and rewards, ordinary immortal officials could only accumulate them over time. It was worth noting that different Dao Fruits made use of Dao Sources with varying efficiency: the higher the grade of the Dao Fruit, the more efficiently it used them. In other words, cultivators needed around ten bottles of Dao Source to advance not because one bottle was insufficient, but because low-grade Dao Fruits used Dao Sources so inefficiently.
