Qiao Sang handed over the crystal she had in her hand.
She hadn't thought much about it, simply feeling that the Ghost-absorbing Lantern had worked too hard to scavenge and deserved some help.
She recognized this crystal, called a Nether Yang Crystal, which contained energy capable of achieving an effect similar to absorbing life energy.
It wasn't something taught in school, but rather from a very popular film she had seen before.
In the film, a Spectral-type Pet named Ghost Treasure was a major villain that absorbed human life energy, and the protagonist escaped from death three times by relying on the Nether Yang Crystal, which left a deep impression on her.
Without its Lamp Wick, the Ghost-absorbing Lantern logically wouldn't last long outside, but seeing the Nether Yang Crystal, Qiao Sang had no more doubts.
