The Book of Life fused with Yusuf Zuck seamlessly, under the interaction between the Book of Flame and the Book of Earth, the Book of Life also found residence deep within his soul.
However, this Book of Life was shrouded in mystery; the scroll that resulted from his fusion was, astonishingly, blank.
That's right, just like when he fused with the Book of Earth years ago, when the Book of Life was unfurled, it was just a blank page with nothing inside.
Of course, even though there was nothing, after fusing with the Book of Life, Yusuf Zuck could sense the rhythm of all living creatures in the world; he could even hear the breathing of plants and trees, and he was able to sense and extract the purest essence of life force.
Nevertheless, the life force he extracted was also absorbed by the Book of Life, disappearing without a trace, like fish diving into the sea.
