The moment the hourglass appeared above Mr. 65,100's pale forehead, Jacob's heart raced, and he instantly knew that he wasn't wrong about this hourglass. It was the same feeling he had when he found those two hourglasses in the ruin of Siren Hymn Temple after killing the final two survivors, and they were extremely beneficial for him.
Although Jacob didn't know who these people with these mysterious hourglasses belonged to, one thing he was sure of was that he wouldn't be going to miss this chance at all.
Without hesitation, Jacob stabbed his sword into Mr. 65,100's head, but to his surprise, it easily bypassed Mr. 65,100's corporeal body, and at this moment, Mr. 65,100 seemed to have activated some kind of magic as a phantom of a half-filled dark framed hourglass appeared behind.
