章 305: Endurance

"Nine times is the maximum number of times that an herb can be tempered. Unfortunately, my best record is seven temperings." Hongzhu said and sighed.

However, she didn't entertain any thoughts of giving up.

Just because she had never tempered an herb nine times didn't mean she couldn't do it.

After clearing her mind, Hongzhu wrapped the soul gathering herb essence with her soul power.

When that was done, she made a seal with her right hand and pushed it at the herb essence.

At the same time, her soul power infiltrated the herb essence and black smoke rose from it.

This smoke was herb impurities.

If the impurities were not removed, the soul replenishing pill could not be refined. Even if it could, the quality would be inferior and may even harm those who took it.

The black smoke rose continuously and finally dissipated after an incense stick of time.
