Duanmu Huai never doubted whether Morag could be defeated.
The reason is simple.
Can the Sword Saint block a nuclear bomb?
Of course not.
No matter how extraordinary your swordsmanship, a nuclear bomb will still reduce you to ashes.
The reason is simple.
All fear stems from a lack of firepower.
Similarly, as long as there is sufficient firepower, any problem ceases to be a problem.
The reverence humans have for deities stems from this.
It's not about deities creating or protecting humans. Plainly speaking, deities possess power and forces beyond human imagination, which is why humans possess fear and respect for them.
That's all.
Like Morag's attack, indeed, as a Demon God, he could fling a palace as large as a city, which was unimaginably powerful in the world's eyes. His towering figure tens of meters high was untouchable to mere mortals.
But… that's it.
Can he blast a hole into Mars?
Well, probably not.
Unfortunately for him, Duanmu Huai can.
