The coffin was crafted from dark yinwood, with eight spirit talismans glowing a ghostly green pasted around it. The runes entwined with one another, containing baleful yin energy.
Moreover, Xu Changqing had keenly noticed something.
The coffin lid was covered in dense, ancient inscriptions.
These inscriptions were neither seal script nor clerical script, their strokes twisted like living things.
Their style resembled that of the Inscription Ancestor, only they were far more ancient and obscure.
Xu Changqing extended his Divine Sense toward the coffin, only for the talismans outside to block it completely. He could not penetrate them at all, and his brow immediately furrowed. "This coffin?"
"What about the coffin?"
"The inscriptions on it are quite similar to those on the Ancestor!"
"These inscriptions contain immensely powerful baleful yin force. Their arrangement looks chaotic, but it actually conceals a certain pattern, like some ancient restriction!"
"The coffin drifted down from upstream. Something may be hidden over there."
"Should... we go take a look?"
Xu Changqing, Zhurong, and Tai Bai stared at the coffin bobbing in the Nether River not far away, the gravity on their faces even more pronounced than when they had encountered Nether Beasts.
In the world of cultivation, the more mysterious and remote a place was, the more one feared running into something both ancient and incomprehensible.
Based on his memories and abilities, Xu Changqing deduced that the spirit talismans on the coffin were likely an extremely ancient Yin-Sealing Talisman.
To put it plainly, it locked something inside, preventing it from coming out.
More importantly, the Ancestor's inscriptions were already ancient enough, yet the inscriptions on this coffin were even older. That was simply unbelievable.
Therefore, barring any surprises, something related to these inscriptions was hidden in the depths of the Nether River, or somewhere upstream.
