The collapse of the entire dimension was the fire of rebirth they ignited with their lives.
The Supreme Mother, Ling, is in charge of the eternal laws, but she steps down from the throne for her daughter and is willing to exchange destruction for new life;
The fateful daughter ended up burdened with the shackles of the curse, but under the protection of her sisters and mother, she broke away from her fate and remained a pampered child forever.
This is an affectionate bond between women——
It's Tian Jing's best-effort protection for her sister, it's the firmness of all the sisters' team who are united as one, it's the loyalty that is ultimately supported by life, and it's Ling and Ultimate's mutual support across dimensions, life and death.
When the galaxy returned to calm, the two peach trees relying on each other were the only proof that they had been there.
Purpose: Female protection and bonding across dimensions are the only force against fate. Gentle love and firm sacrifice can break all curses and shackles, allowing the loved one to remain a child forever, and the lover to stay together forever.
