The Invisible Demon was so excited that it fell to its knees and said, "I'm privileged to receive your source-type power. I definitely won't disappoint you and successfully evolve to Class 12."
After all the time they had spent together, Lin Yuan knew that the Invisible Demon was very cautious and would not attempt to do anything that it did not have the confidence to achieve.
Otherwise, it would have jumped at the chance to go through the Source-Type Cleansing the last time Lin Yuan offered instead of waiting until it could evolve to Class 12 and use the Source-Type Cleansing to kill two birds with one stone.
But now that the Invisible Demon was taking the initiative to ask for the Source-Type Cleansing, it meant that it was confident it would succeed.
Lin Yuan had asked White Speak if dimensional lifeforms would encounter any risk when they evolved from Class 11 to Class 12.
