Four Season Monarchs

The Saintess was acquainted with the Ever Spring Mistress for a long time and knew about her abilities too.

The Ever Spring Mistress was highly proficient in the Dao of Spring and was able to tap into its power that was not accessible to others. She had reached a level with it where only a few had ever reached since the creation of the cosmos.

Spring was the symbol of beginning and the signal of things that are to come.

As such, the Dao of Spring allowed one to do much more than was conventionally thought. The Ever Spring Mistress took this a step further and was able to 'ask' the Spring questions.

Since Spring had existed from ancient times, it had seen many things. Similarly, most beings had witnessed spring and had been through it. As such, the 'Spring' knew their history. It knew when they were born and when they were reborn.

It knew if they had a history that was unknown.
