"Ding, get the skill upgrade book*1!"

Looking at another skill upgrade book, Zhang Fan was elated.

He has driven this thing before and has always been reluctant to use it.

Because every time a martial skill is upgraded to a level, the experience required increases tenfold.

It can be said that a skill upgrade book can save countless spiritual points later on.

It is no exaggeration to say that it can even save one billion or billions of spiritual values.

Therefore, Zhang Fan was reluctant to use this thing directly.

"Ding, congratulations to the host for upgrading his butterfly dance martial arts to LV7!"

"Ding, congratulations to the host for upgrading the butterfly dance martial arts to LV9!"

"Ding, congratulations to the host for upgrading the butterfly dance martial arts to LV10!"

"Ding, the butterfly dance step martial arts reaches the full level, does it evolve?"

Seeing this system prompt, Zhang Fan's eyes suddenly tightened!

evolution?

Damn it, martial arts can still evolve?

What the hell is this?

Soon, Zhang Fan noticed a line of small words behind the butterfly dance martial arts button.

"Butterfly Dance Step: LV10 (full level, can evolve! Evolution requires 50 million spiritual values, speed increase, 50%!)"

Damn it, fifty percent?

Zhang Fan was shocked!

A fifty percent increase, how terrifying that is!
