Storage Card!
As the name implied, Storage Cards were cards that could store items.
It's interior was an independent space that could be sealed on any part of Su Jingxing.
In other words, the small space obtained after the Storage Card was unlocked could be placed wherever Su Jingxing liked.
His chest, shoulders, eyebrows, thighs, arms…
Anywhere!
To facilitate retrieval and storage, Su Jingxing decisively placed it in his palm.
Right palm!
The next time he extracts a new Storage Card, he would place it in his left palm.
The storage space in his palm couldn't be seen by the naked eye or felt. Only Su Jingxing's mind could enter and exit it at will.
Su Jingxing checked carefully and confirmed that the storage space was 10 meters long and wide, and two meters tall.
Although it wasn't very big, it was enough for Su Jingxing's current use.
