章節 690: Heading for the Chaos Turbid River

Meng Chuan looked at the black book in front of him. On the surface, this book is an opportunity to become the disciple of an Eternal existence. However, what's precious is the 3,000 illusory arrays.

It was probably very difficult for an Essence Soul Eighth Tribulation Eminence to crack all 3,000 illusory arrays.

But after each array formation was broken, one would gain a deeper understanding of illusory arrays. Perhaps after breaking 1,000 illusory arrays, one would have a chance of grasping the laws of time and space.

Although the effects on one's strength were negligible now, and it was far inferior to the strength increase brought about by the fruit, the benefits brought by the black book would probably be much greater over a long period of time. However, if one's cultivation realm wasn't high enough, they wouldn't be able to understand the illusory arrays much. Therefore, how much they gained depended on their potential.
