At least he didn't think of that possibility.
Gazing at the giant head that was still emitting surging energy, Youyou, floating beside Luo Yan, spoke nervously.
"Lord Demon King! That guy seems to be immune to physical attacks, all the earth you hurled at him just passed right through his body!"
"I know." Luo Yan replied calmly in the Sea of Consciousness to Youyou, and then continued in an understated tone, "And I never said I was going to bury it with soil."
He obviously knew that it was impractical to think that a mere handful of soil could extinguish the projection of Calmandes in this world.
If it were that easy, the storm raging in the Dimension Desert wouldn't have made the Imperial so nervous, even to the point of feeling like facing a formidable enemy.
Plainly speaking.
The Flame of Destruction wasn't really a flame at all.
