A sickly girl, but there is a world of immortality in the box

When she found that she could only live in a wheelchair after time travel, Amelia Su was at a loss. She didn't know how she would face the world in the future.
It wasn't until she was sorting through the memories of the original owner that she discovered that there was an extra landscaping box in the bedroom.
After some inspection, Su Xiaoyu was surprised to find that there was a microscopic world in the landscaping box.
This world has mountains and rivers, and a group of villains who call themselves immortals fly around, showing the grievances and resentments that belong to the world of immortality.
Su Xiaoyu put in a pebble, which caused a large number of immortal cultivators to gather and compete for it, calling it the Kunwu Stone that can create magical weapons.
Su Xiaoyu accidentally dropped a drop of milk, which was regarded as fine wine and jade liquid, and everyone coveted it.
Su Xiaoyu put in an isatis root, which was regarded as a fairy medicine, causing shock in the world of immortality.
She put her hand in and flicked it with her fingers, causing blood to splash into the sky.
