A Temporal Demon Spirit Book appeared out of thin air into Nie Li's palm.
The Temporal Demon Spirit Book immediately emitted a dazzling light, enveloping Nie Li and Yu Yan within.
"What kind of treasure is this Temporal Demon Spirit Book?" Yu Yan curiously asked.
"This is the strongest treasure in the world!" Nie Li lightly smiled.
"The strongest treasure in the world?" Yu Yan was a little puzzled, "What kind of treasure is worthy of such a title?"
"In this world, the most powerful things are time and space. Time can turn everything into ashes and space can tear everything apart. With this Temporal Demon Spirit Book, we have the capital to fight against the Sage Emperor." Nie Li lightly smiled and said, "I once possessed the Temporal Demon Spirit Book, but I lost it later on. I never managed to find it until today."
"Then, how is the Temporal Demon Spirit Book used?" Yu Yan asked.
