The formation had already failed, and the Strange Beast within it was a Flying Centipede—a gigantic, venomous centipede over ten meters long. Moreover, it was female. In other words, once released, it could continuously breed offspring. That would leave them with nothing but the ability to stare helplessly at the treasure, unable to do anything.
Fortunately, although Lan Caiyue had been stung and poisoned, Lan Caijie used the Talismans left behind and her knowledge of formations to seal the creature away once more. Of course, all the Spirit Stones and Talismans she had on hand were completely used up.
