Under Mu You's suggestion, Little Ya headed straight for the tall grasslands upon entering the Titans' world and found the Silver-tailed Fox, attempting to tame it with the Evolution Scepter.
The Evolution Scepter was a professional taming tool, a Hidden Relic no less, and even in the Titans' world, its effect should not be diminished.
The result was indeed as expected, under the Evolution Light, the Silver-tailed Fox became even more docile and obedient than when facing Mu You, and to the end, it did not turn aggressive and slap Little Ya to death.
Unfortunately, Little Ya still succumbed to the first wave of the tsunami.
Perhaps because the light exposure was insufficient and the fox had not been completely tamed, the Silver Fox Tail could only watch as Little Ya was swept away by the tsunami, choosing not to save her.
