Chapter 397: Heavenly Thunder Dao Body!

At this moment, demonic lightning surged in the clouds.

The lightning was extremely powerful and it could destroy the world! It slashed down crazily.

Outside the cliff, it was as if the end of the world had arrived.

As for the Ninefold Lightning Shield Seal…

It was one of the higher ranked defensive seals among the basic seals in the book of seals.

However, the synthesis conditions were extremely high.

It required nine different types of lightning to build the Ninefold Lightning Shield.

This was to achieve a defensive effect!

However, the effect was absolutely shocking.

That was because the defense of the Ninefold Lightning Shield could be increased according to the level of the lightning.

Therefore, the Ninefold Lightning Shield Seal was more like a growth-type seal.

It had the same effect as a growth-type weapon!

But now…

The basic seal of the Ninefold Lightning Shield had been engraved.
