In the generations before the Cold Abyss Divine Palace, Formation Masters capable of refining Sixth-ring Dao Formations had appeared as well, so there had originally been a certain stockpile. It was only because four Sixth-ring Dao Formations had been taken away for the construction of Lingxiao Immortal City that the Cold Abyss treasury's high Dao Grade formations had nearly been exhausted.
If there were no wars, naturally there would be no issue, and no drawback would reveal itself. But as a leader, the Snow Emperor had to prepare for hidden dangers before they arose, guarding against Qingming Hetong Heaven encountering another large-scale war like Sun and Moon Shine Together, or going to war with other major powers in the same world over interests.
Once wartime began, high Dao Grade formations like these were extremely useful strategic weapons. There was nothing more worry-free or labor-saving than formations for guarding strongholds everywhere.

The Snow Emperor understood that you wanted to gather the four Sixth-ring Dao Formations needed for the Four Symbols formation, as was plain to see from your sale of the original four sets of formations to Jue Zilian. Therefore, she had only made a tentative request.
After considering the Snow Emperor's request, you ultimately decided to agree, because before gathering the Six-Ring Dao Grade Four Symbols formation, you still had something more important to do: bring the Drunken Earth Dragon back from Supreme Changrong Heaven.
