Every creature in the woods either perished or was harmed. When swallow mommy returned, clutching food, all that remained was a charred stump. The forest had turned to ash and broken branches, devoid of any greenery.

Mommy swallow flew round and round, crying out in despair for baby swallow, but the familiar cheerful call of "Mommy" was gone.

After the wildfire, mommy swallow stayed in the devastated forest.

She watched as compassionate people came and restored it. She soared across the sky, tirelessly searching for Angelica Sinensis, until at last, she found a tiny one. She waited for a rainfall, then carefully unearthed the damp soil and tenderly carried the Angelica Sinensis back to where their home once stood.

The giant tree where she had nested was no more, replaced by young saplings. Mommy swallow planted the Angelica Sinensis next to a sapling, hoping they would grow together. She stayed by that sapling, year after year, until it grew large enough to support their modest nest, though it was still not very big.

Mommy swallow collected numerous twigs and soft leaves to craft a cozy nest. In this new nest, she kept waiting, hoping for baby swallow's return.

As the years passed, the sapling became a large tree and the lone Angelica Sinensis multiplied into a cluster. Mommy swallow grew old and could no longer fly. She had been in the nest for four days, too weak to leave for food or drink.

In a daze, she heard a faint chirp. Thinking she was mistaken, she opened her eyes and looked around, but found the space before her nest empty. Slowly, she closed her eyes again.

Mommy swallow was getting old, no longer able to fly far like she used to at the sound of a familiar call. These days, she found it hard even to leave the nest.

Overcome by sleepiness, mommy swallow slowly lowered her head, no longer feeling hungry. She realized her time was running out.

Just then, another familiar sound came.

Mommy swallow didn't open her eyes, thinking it was just her imagination.

The calls persisted, clear and vibrant.

This time, mommy swallow opened her eyes and saw a fluffy little head snuggling against her.

It had a familiar voice and scent. She knew it was her baby that came back.

The local people later spread this story, concluding it with “Birds return when the time comes."

As the story concluded, Casey's daughter still wasn't asleep. She lay with wide, teary eyes. "Mommy, mommy swallow is so incredible, so determined."

Casey gently wiped away the tears from the corner of her daughter's eyes and whispered, "Because mommy swallow never stopped believing that her baby swallow was alive. She waited and waited, and finally, she saw her that day."

“Mommy, what if I get lost?" Casey's daughter looked up at her with wide eyes. “Will you keep searching for me, waiting for me like mommy swallow did?"

“Absolutely, I'll never stop searching for you, my love. I'll wait for you to come home, no matter what."
