Kapitel 560: Merman’s Meat

A faint smoke flowed out from the Jar of Sealing Fiends.

Kieran carefully backed up to the wall as he witnessed the scene.

Although Lee had been evasive about the jar before, according to the information Kieran gathered throughout the night, the jar was exactly what he had first speculated: a treasure chest.

The treasure chest was passed down from an unknown era and what it held inside was anyone's guess.

In simple words, the things inside might benefit fiends or humans.

Though, according to the books, most items that benefited humans would cause damage to fiends and vice versa.

There was also the exception that the item might benefit both sides but to determine what it was, it would depend on one's luck.

However, it was not exactly Kieran's assumption.
