Qi Shi already knows about the space, which is essentially the children's Immortal's Blessing. Isn't such a magical place with magical abilities an Immortal's Blessing?
Even at this point, it still seems unbelievable, but it doesn't stop her from lecturing her child.
Pointing at her daughter's forehead with a face full of lingering fear, she said, "Even if it is true, you can't be careless. What if something goes wrong?"
"Mom, don't worry, I know what I'm doing. I can enter the space at any time if there's danger." Jin'er tilted her head that was nudged by her mother, blinking playfully and swinging her other hand holding her mother's arm.
"Mom and Dad, do you want to go in and take a look?" Jin'er changed the topic with a suggestion the two couldn't refuse, successfully shifting the conversation and reacting like any normal child would.
