The Ice-fire Explosion, a combination of two elements in a special form, undoubtedly unleashed far more power than a single power could. This was Du You's own experience.
This special landmine would only explode when it sensed the presence of life approaching. Previously, it was Du You who triggered the explosion.
After all, it's a landmine created by Du You himself, he can control it as long as it's within the range of his Spiritual Perception. However, once it's outside his perception range, he would be helpless, and it truly becomes a landmine.
It's just a pity that such a powerful magic spell can't be used in combat. No opponent would watch him create an Ice-fire Landmine and then stupidly step on it.
Having composed himself, Du You set off again. The next task involved the Black Mountain Goat.
