章 1816: Progress Underground 

After a few moments in this green area, Isabella and Harold finished their meditation and made important progress.

The red-haired young woman did not advance like her father, for she had suppressed the medicinal effects of the herb she had ingested, just like Minos.

Unlike her old man, she was still in the prime years of cultivation and could not take things lightly. If she increased her cultivation and destabilized her foundation, her future progress at the 10th stage would be greatly hindered.

But she had gotten a good return from taking the Saint herb, which greatly improved her understanding of flames.

If someone asked her how much she had gained, Isabella would answer without hesitation that she had saved 5 years of hard work in the minutes she had meditated in this green area!

She was only at the beginning of the 9th level, but her understanding of flames had jumped from the low level to the middle level of this stage.
