This will have to wait until he cultivates to the third heavenly layer, and right now, he hasn't yet obtained the second ice jade and third fire jade corresponding to the cultivation methods of Ice Jade Eye and Fire Demon Eye.
To truly control flame and ice, there is still a long road ahead.
Lu Yu can now partially grasp the Fire Demon Eye, all by chance, completely opened under a series of coincidences. He can only use it but cannot cultivate or actively advance the mastery of the Fire Demon Eye.
Because there is no cultivation method, not even allowed to add experience points.
Now that Lu Yu has lost his double experience point buff, his cultivation speed has greatly reduced. Even if he goes to the cultivation hall for a retreat (which costs money), it would take at least a week to cultivate Ice and Fire Spiritual Power to the limit.
