"Isn't this too easy?" Cheng Yifeng still found it hard to believe.
The main altar of the Evil Sect, mysterious and powerful, an unshakable existence.
If it weren't, the Evil Sect wouldn't have existed for so many years.
Yet, such a formidable stronghold was no match for Chu Zhiyuan, easily destroyed with a flick of the hand.
This contrast struck him intensely.
Chu Zhiyuan laughed, "For those who know, it's not difficult; for those who don't, it's impossible. Once you find their weakness, they crumble with one blow... Let's go in."
"...Come, let's go in and have a look."
Cheng Yifeng snapped back to his senses and nodded fiercely, "Let's see what their main altar looks like!"
The two floated in, reaching the valley.
The silent valley, under the sunset, was almost soundless.
Standing in the valley, one could hear the wind rustling from afar and the chirping of birds.
