Chapitre 724: Too Good to Be True? (1/2)

The emergence of the mysterious object in the hands of the Water Spirit leaves Lucien and the Sins impressed.

She says that it is a key, but the aura of that circle of blue stone is incredibly magical, undoubtedly a creation of her own.

If it is a key, it naturally must unlock some lock or door, which raises Lucien's curious question.

"Well," the Water Spirit thinks before responding and then looks at the blue horizon. "If you see the Blue Star as a house and my barrier as impenetrable walls, this key opens the only way in and out."

"What?" Lucien becomes confused with that answer.

Despite understanding a lot about feminine feelings, his general knowledge is still that of a human almost twenty-one years old who has lived most of his life locked away in a distant fortress away from everything.

"It's a portal key," the Water Spirit explains.

Not only Lucien, but the Sins are also very curious to understand how that key works.
