A deadly earth vein.
This was the first threshold of the Feng Shui Master's advancement ritual, and its most crucial foundation.
An ordinary mass grave or a haunted house where a few murders had occurred simply lacked the scale to qualify as an earth vein.
Anything called an earth vein had to be a vast formation that shaped the flow of fortune across an entire region.
Li Xiang had narrowed his options down to two locations.
The first was Qing Xuanji's Corpse-Transformation Tomb.
Li Xiang knew that place all too well.
Sun Jingui had once dragged their hastily assembled team there, and it was in the Main Burial Chamber that Li Xiang had completed his Feng Shui Master unlocking ritual in one stroke, drawing on the immense Corpse Qi of the Former Dynasty's prince-turned-jiangshi and the Feng Shui formation.
Without question, an underground mausoleum capable of producing a flying jiangshi of royal blood had to sit above a first-rate deadly yin vein. It met the advancement ritual's strict requirements perfectly.
But there was one risk he could not ignore.
"I stripped that tomb bare, and its Main Burial Chamber's Feng Shui nexus took some damage. Does it still hold enough Yin Baleful Intent to sustain a complete reversal of the earth vein?"
He had no way of knowing.
If the earth vein's baleful energy ran dry halfway through and the reversal failed, he would suffer a backlash and waste precious time.
His second choice was the Ruins of the Riverside Demon City.
Linjiang Demon City had once occupied a natural basin outside Linjiang County.
To a Feng Shui Master's Qi Observation, the terrain of the Ruins of the Riverside Demon City formed a rare, top-tier Qi-Gathering formation called Jade Toad Gazing at the Moon.
Mountains ringed it on every side,
