From the record in the book, it would be more painful than the first one, so he was a bit hesitant. Even so, he had to swallow the blazing seed.
His Pure Fire immediately came out of his Fire Phoenix Seed and suppressed the fire on the Blaze Tree Seed. The fire energy within the seed melted and spread throughout his body before fusing with his veins. It was then his Pure Fire flared up and burned all of his veins. This was to help the assimilation process.
The pain had yet to start, but Alex had made a Sound Insulation Room. This way, no one could hear him screaming like the first refinement.
The fire started becoming bigger and bigger before it slowly seeped through the pores, dancing around his body like having a ritual. When the fire finally covered his body, it was at this time Alex finally started feeling the pain.
