143 Rumbling Tail Strike + Fireball = ?

Fireball.

It was the lowest-level spell in the cultivation world.

Basically, everyone in the Qi Refinement realm knew it.

With spirit energy as the driving force, cultivators with strong aptitude could learn the incantation of the Fireball Technique in one go.

Those who were not talented would need a few days or even a few months.

The power was determined by the user.

It could be very strong or very weak.

Immortal Ascension cultivators could easily destroy an area of hundreds of kilometers with a small fireball.

It was not a simple low-level spell.

Instead, it was an ultimate fireball formed by pure True Essence, together with the Embodiment of Heaven and Earth, and the transformation divine arts with the power of the Great Dao.
