In such a situation, why should one take the risk of conquering a Minor World? Success would merely save a little time, while failure could lead to the collapse of one's Dongtian. If unable to meet the Heavenly Dao of the Spirit Realm's tax demands, one might face death and the dissipation of their Dao.
But to Daoist Venerables, what's a little time?
The risks and gains are completely disproportionate.
That's why the Daoist Venerables, True Spirits, and Primordials are as elusive as dragons — they might occasionally attack a world on a whim, not necessarily aiming for success, but rather seeking amusement in their endless lives.
This is indeed why the many worlds of the Void exist.
However, Yu Xian has always possessed a spirit of skepticism towards authority in his quest for truth.
Even if what Haotian Daoist Venerable said made perfect sense and was logical, Yu Xian always felt there was a deeper reason.
