Submerged Creek Stronghold

Tang Yuan asked with a glimmer of hope, "Did Senior mention any solution? What kind of beast core would be a perfect match for me?"

From the countless books in the Book Sea, Tang Yuan had gained a certain understanding of beasts. Because his first beast core had been the Black Dragon Core, the range of choices for his second core had been restricted. Their grades could not differ too greatly. With that, suitable beast cores became exceedingly rare—each one something that could only be encountered by chance, never sought.

Seeing Tang Yuan's despondent expression, Ruo Shui said, "Senior said you can keep this Black Tortoise Core for now. If you find a Profound Yin Tortoise Core someday, it can assist in refining it."

"A Profound Yin Tortoise Core?" Tang Yuan asked in confusion.

Ruo Shui explained, "Senior said the Profound Yin Tortoise is a relatively rare and special existence among the Black Tortoise clan. Its defense is not simply about endurance, but leans toward using softness to overcome hardness and dissolve force. If you can obtain a Profound Yin Tortoise Core to pair with this Black Tortoise Core, not only will your Beast Art improve greatly, even your Body Refinement Technique will receive an enormous boost."

Tang Yuan's heart leaped with joy. He secretly felt that it made sense, suppressed his urge to refine the Black Tortoise Core, and asked, "Did Senior say where a Profound Yin Tortoise Core could be found?"

Ruo Shui recounted truthfully, "Senior said she once buried one beneath Vaulted Mist Mountain. There is a Profound Yin Tortoise Core in its grave."

Tang Yuan jumped up in excitement. The joy of finding a way out when he had thought himself at the end of the road left him unable to contain himself.

"Vaulted Mist Mountain?
