Mo Qiong quickly figured out the properties of the Black Leather Book.
This thing could be called the Book of Life and Death.
That was because, in the universe where it existed, the original lifespans of all living beings had vanished. Their physiological lifespans, soul lifespans, and everything else had been changed.
Within this book's thin, ten-centimeter text was recorded the lifespan limit of every living being in the universe.
The way they were recorded was extremely unique, and was not limited to time.
Originally, a person's lifespan was measured by how many years and days they had left.
But after the Black Leather Book altered it, it became how many sentences, how many encounters, how many times they would look back, how many smiles, and so on, they had left in life.
The records covered every possibility imaginable.
And this was actually an alternative form of lifespan restriction. It had merely changed from a single measurement of time into all-encompassing events.
For example, suppose the Black Leather Book recorded that a person had twenty exams left in life.
Then, after he completed the twentieth exam, he would die on the spot! And it would be the end of his lifespan—a natural death from old age. It was not limited to the body. Even if his soul were placed back into a perfectly intact body, it would be useless. No, he would not even have that opportunity. His soul would be annihilated directly, and his consciousness would vanish.
Conversely, if he did not complete them and never participated in another examination again,
then his lifespan would effectively be infinite, and he would never die of old age.
"That's terrifying." Mo Qiong frowned.
Blue White Ji said, "Every living being's lifespan limit is different, but it will always be something they
