"What's wrong?" Su Lianqing looked at Xu Qing anxiously.
Just now, she was guarding beside Xu Qing and saw his face turning pale and then blue, which was quite alarming. Su Lianqing knew this might indicate a problem with Xu Qing's Divine Soul.
She didn't dare to interrupt and could only wait anxiously for Xu Qing to wake up.
Xu Qing took a deep breath.
He recalled that when he was visualizing the "Xuantian Taoist," his Divine Soul experienced a great terror, as if plunging into an endless abyss of darkness.
The reason he could escape from the darkness was that he had ignited his first Hidden Vein—the Purple Emperor Meridian.
There are thirty-one Hidden Veins in total, including three main veins, also known as the Tri-Guardian Emperor Veins, which are Purple Emperor, Taiwei, and Heavenly Market.
