Chapter 421: Remains of the Thunder Beast

The world knows that Jun Xiaoyao has many methods and hides them deeply.

However, there is one trump card that outsiders are unaware of.

That is the Body Book, one of the Nine Great Heavenly Books.

The Nine Great Heavenly Books can be said to be the supreme inheritance, with each book representing the pinnacle of a certain path.

For example, the Body Book represents the ultimate path of the physical body.

Any Heavenly Book, if cultivated to its peak, possesses unparalleled great power, serving as an absolutely formidable trump card.

It is even rumored that if one can gather all Nine Great Heavenly Books, they may glimpse the path to immortality.

The value of the Nine Great Heavenly Books goes without saying.

However, cultivating them is also extremely difficult.

Even with Jun Xiaoyao's foundation, it took a considerable amount of time to cultivate the upper volume of the Body Book.
