This is the advantage of being well-stocked. Ye Hanjun couldn't possibly leave the first Contract Imprint of his Demon Servant vacant for long.
Due to the vast discrepancy in rank, he couldn't dare to serve this hard-to-please master, risking further fragmentation of the seal.
Without serving, the Demon Servant would not be able to accumulate Experience Points.
Without Experience Points, by the time the Instructor reaches the second rank, the Demon Servant would still be stuck at the first rank.
-- Dual authority, although coexisting, remains separate and do not share ranks.
In fact, in the eyes of the highest beings, dual authority represents uniqueness and a stronger initial combat power.
But from the mid-stage, dual authority becomes an obstacle to growth. Each rank crossing requires multiples of time, energy, wealth from a single rank... The further one goes, the more difficult it becomes.
Ye Hanjun need not worry about this in the short term.
