Miao Yu couldn't help but be shocked.
Her knowledge indeed far surpassed other Immortal Kings, but it was precisely because she knew more that she understood the significance behind this.
The number of Main Rules was fixed at the moment the Holy Sanctuary forms.
There's no possibility of increasing it thereafter.
Even if one conducts more profound research on other rules later on, they will always remain Secondary Rules.
Because of this reason, many Great Powers in the Immortal Realm deliberately let their juniors stay at Ascending to Saint Ninth Layer for millions of years.
Only when their life span is almost exhausted do they allow them to breakthrough to Saint Tier.
The aim is to accumulate and subsequently soar, hoping that at the moment of achieving the Holy Sanctuary, they can possess as many Main Rules as possible.
Even gaining just one more would be a huge advantage when becoming an Immortal, Immortal Venerable, Immortal King, or Immortal Emperor!
