Tang Zirui was deeply astounded.
Even in the Ancient Era, there were not many cultivators who could refine the Dragon Vein Protection Talisman to such an extent.
But now, the Dragon Vein Protection Talisman was everywhere.
Almost every city was under the protection of a Dragon Vein.
He knew just how powerful the Dragon Vein Protection Talisman truly was — it could summon a True Dragon and manifest the True Dragon Domain.
Once activated, it could suppress all cultivators in the area, stripping them of their various abilities.
It was like being trapped in a prison, unable to move.
Even according to his own cultivation, entering Julu City would likely result in him being instantly suppressed.
The Dragon Vein could even ward off demons and demonic forces, truly an endless mystery.
"Without a doubt, cultivators of this era must have realized the threat of demons."
"They might even be aware of some ancient secrets from the Ancient Era and the various crises."
