Gateway of Immortality

Unexpectedly, Shopkeeper Wu recognized it at a glance and exclaimed in shock, "These are Profound Yin Thunderbolts!"

Seeing Qin Sang's puzzled look, Shopkeeper Wu took the initiative to explain, "Artifact refinement may be a small branch of study, but as you focus on the path of cultivation, Daoist Qin, you may not have heard of the Profound Yin Thunderbolts. Several thousand years ago, Profound Yin Thunderbolts were famous demonic artifacts, originating from a demonic sect called the Youshen Sect. These artifacts once struck fear into righteous cultivators. In the world of immortal cultivation, they were as renowned as Heavenly Thunderbolts. After the fall of the Youshen Sect, the method of refining these thunderbolts was lost, and it's been many years since they’ve been seen..."

As Shopkeeper Wu spoke, he moved closer, holding the Profound Yin Thunderbolts with great admiration, examining them over and over again, as if he wanted to engrave their details into his eyes. His face was filled with fascination as he repeatedly praised, "What fine artifacts! Such exquisite craftsmanship!"

Qin Sang nodded. "I obtained them from a demonic cultivator. What’s so special about these Profound Yin Thunderbolts?"

Shopkeeper Wu, now serious, replied, "It's fortunate that Daoist Qin didn’t allow that demonic cultivator to activate the Profound Yin Thunderbolts! These are one-time-use artifacts, just like the ones I mentioned earlier. With a mere activation of the barrier using one's spiritual consciousness, they can be detonated, unleashing terrifying power. Their might is astounding, and even a Foundation Building cultivator could be severely injured if caught off guard. The only downside is that their range is somewhat limited. The core explosion covers only about one zhang, with the residual impact much weaker."

Hearing this, Qin Sang couldn't help but feel a chill. Back at the bottom of Yuanzhao Peak, when he fell into the Soul-Devouring Array of Three Calamities, he hadn’t witnessed the full explosion, and he hadn’t realized that even a Foundation Building cultivator could hardly withstand it.

The power of the Profound Yin Thunderbolts was far greater than he had imagined.

The two Profound Yin Thunderbolts that Zhao Yan had must have been given to him by Yi Tianye as a defensive measure. To secure the Nine-Illusion Heavenly Orchid, Yi Tianye had clearly spared no expense.

If he hadn’t reacted quickly and fled, he might have been reduced to dust by now.
