Although there exists a being capable of restraining the Star Gods, without sufficient time to grow, and given the overwhelming number of Star Gods, unless Yao Xing can grow to the point of crushing all Star Gods in a short time, her only fate is death.
A being like her should not have appeared in this world, and, just because she became such a being, will not transform her into a role like the Son of Heaven's Mandate.
Her appearance was merely an accident. Zheng Yichen thought for a moment, then directly assigned her a new identity, a new crew member of the Firmament Wheel.
While they might not lack people there, they lack true individuals. With Yao Xing's uniqueness, becoming a crew member of the Firmament Wheel is not an issue. Anyway, possessing 'Star' attribute specialization, there will always be times to play a role.
But before that, she must first grow, and this world is an ideal region for her to grow.
