Chapter 121: Jade Slip
A sudden gust of cold wind arose.
The Yan Luo Banner of Ten Directions fluttered violently, continuously releasing black clouds of yin qi that sealed off the narrow passage completely. The underground chamber became pitch black, filled with the sound of ghostly wails and eerie sobs, making it seem like a realm of the dead.
After acquiring Sun De's Yan Luo Banner of Ten Directions, Qin Sang refined it and made it his own, but he didn’t further enhance its grade.
To raise all six banners to top-grade artifacts would require an immense amount of sacrificial souls and blood offerings. Countless mortals would have to die for that, and even seeking a war-torn nation wouldn’t yield enough.
If he were to slaughter innocent mortals to refine artifacts, he would be no different from the demonic cultivators.
Nevertheless, even without further upgrades, the power of the Yan Luo Banner of Ten Directions was formidable.
Once the array was activated, the six Yan Luo Banners would complement each other, and the increase in power was far more than just doubling.
After sending the cat demon away, Qin Sang engaged Gu Tiannan in conversation to buy time and prepare the Yan Luo Array of Ten Directions.
As the banners whirled, the black qi swirling on their surfaces formed vortexes that grew larger, eventually transforming into black holes. More black qi surged out, making the cave bone-chillingly cold.
