Gently untying the red string that was attached to the Demon Mirage Crystal Core, Ling Feng thought it over and decided to keep the red string.
After all, this could be considered a "gift" from his student to himself. The Demon Mirage Crystal Core was undoubtedly beyond saving, but the red string could be kept as a memento.
The other three top alchemists exchanged glances, not minding this minor detail, but curious to see how Ling Feng intended to handle the Demon Mirage Crystal Core that had been sealed for over a decade.
It could be said that the Demon Mirage Crystal Core was of utmost importance in refining the Demon Transformation Elixir. If the crystal core was mishandled, there would essentially be no chance of successfully refining it.
In the next moment, Ling Feng activated his Earth Fire True Qi and began to gently smelt the amber layer that had formed on the surface of the Demon Mirage Crystal Core.
