Time always passed quickly during training. In the Soul Devouring Tree's world, eight days had passed since Xu Le and Chi Xiao began training separately.
As a combat genius, Chi Xiao had made tremendous strides in using her own energy over those eight days.
She could already exercise basic control over the energy of her purifying flames.
The awkward part was that she could now use some destructive spell formulas that demanded large amounts of energy.
Flame Explosion, Flame Dragon, Flame Emperor, Flame Demon, and other extensions of legendary might, for example.
These spell formulas all shared certain traits: brutal, simple, effective, and costly in spirit energy.
Their specific structures were not particularly intricate.
Chi Xiao could already use these less intricate spell formulas.
But the awkward part was that she still could not reliably control abilities such as Great Flame Realm, Flame Prison, Flame Serpent, and Ring of Fire Resistance.
The destructive power of the purifying flames was simply too great, and their stability was far from sufficient.
Especially with a sealing spell formula like Flame Prison, she would probably need at least one or two months of practice to fully regain her previous standard.
One or two months really was not a long time.
But for Xu Le and Chi Xiao as they were now, it was.
The Children of Guyinduo were racing against the clock, and so were they.
"Eight days... the more intricate the spell formula, the harder it is. That's rather unexpected. Still, in my current state, I should be good enough to serve as a high-level fighter."
Now that she was working with Xu Le, Chi Xiao had a clearer sense of her role.
Xu Le would tie the enemy down and control them, while she delivered the burst damage.
That was the best
