This was an underground secret chamber of the Alchemist Guild. A Dou Wang powerhouse stood guard outside in secret. When Yan Lin and the other two arrived, they all sensed the Dou Wang's scrutiny. But perhaps because he saw Fama, the man quickly concealed himself again.
"A Dou Wang standing guard? Old Fama, your Alchemist Guild is certainly willing to spend big, hiring such an expert to hold down the fort."
Looking at his old friend beside him, Hai Bodong smiled meaningfully.
Fama glanced at him and merely smiled without replying.
The treasure vault was the Alchemist Guild's foundation, so naturally it had to be well guarded. Hiring a Dou Wang powerhouse was nothing much to the Alchemist Guild.
At the entrance to the secret chamber were several concealed doors, each storing things such as the Alchemist Guild's pill formulas, alchemy ingredients, tools, and more.
Fama led Yan Lin and the others to the entrance of the secret chamber where alchemy ingredients were kept.
At a glance, this dark Crystal Stone door was clearly fitted with specialized mechanisms. The walls surrounding it were made of lustrous black Crystal Stone, and even a Dou Wang powerhouse would find it difficult to break through.
Yan Lin recognized this black Crystal Stone. It was an exceptionally durable ore, even sturdier than the black rock of Black Rock City.
There was also a layer of energy barrier outside the Crystal Stone door. Touching it would trigger the mechanisms here and sound an alarm.
However, with Fama present, there was no chance of such a blunder. He fired an invisible strand of soul energy at the energy barrier, sending it straight into the Crystal Stone door. Soon, the door trembled, the energy barrier dissipated, and the Crystal Stone door slowly opened.
*Soul authentication? That's even
