Immortal Nine Forge

It was only after communicating with the Sacred Sword Wielding Queen that Lin Yuan found out that Class 9 and below dimensional lifeforms required 100 additional units of source-type power for Source-Type Cleansing, while Class 10 and above dimensional lifeforms with World Crystals inside their body required 1,000 additional units of source-type power for each higher class.

This meant that Lin Yuan needed 9,900 units of source-type power for the Invisible Demon's Source-Type Cleansing, which was equal to the Sacred Sword Wielding Queen absorbing 9,900 Law Source Crystals.

Lin Yuan's heart ached at the high expenditure.

9,900 units of source-type power could allow him to gain a second sword skill.

Lin Yuan decided to have a proper chat with the Invisible Demon at night to judge its value.
