"The enemy has significant control over intelligence concerning our forces,"
"Duo Lai, Uta, Lu Liu... especially Duo Lai, the enemy is on guard against them."
They could slay these few legends, partly by surprise.
Xi Liu's Red Dragon's True Flame, Jun's Sigh of the Wind God, both had a formidable initial killing effect.
Secondly, they relied on the power of Isloa.
Isloa did not leave her abode, but the power of Destiny Star Weaving kept working, interfering.
Uta could support Jun in time because Isloa, by chance, grasped a thread of opportunity from the Netherworld.
However, such threads of destiny are hard to seize, almost left to chance.
One or two legends acting in the current Ten Directions Island Domain would be inconspicuous, their destinies not evident;
When a dozen or more legends act, the enemy would use some means to conceal it, rendering their destinies indistinct as well.
