Glazed Immortal Turtle, Refining Spirit Treasures

The next moment.

Ye Qingxuan arrived above the largest Spirit Lake in the core area of Qingxuan Cave Heaven.

All the water in the Spirit Lake came from a spring connected to a large Spirit Vein beneath it.

And this water was no ordinary spring water.

It had been compressed from Qingxuan Cave Heaven's World Heaven and Earth Spiritual Energy through that spring.

This Spirit Lake had existed since Qingxuan Cave Heaven was first opened.

It was merely a Spirit Stream within Qingxuan Cave Heaven at the time.

Over the years, as Qingxuan Cave Heaven continued to grow, that Spirit Stream had gradually transformed into the vast Spirit Lake it was now.

Through the seemingly clear Spirit Water, which nevertheless emitted a hazy aura, Ye Qingxuan's gaze finally settled on the ten enormous Spirit Turtles lying motionless in the depths of the lakebed.

These ten Spirit Turtles were the Earth Spirit Turtles Ye Qingxuan had once raised freely within Qingxuan Cave Heaven.

Yet the Earth Spirit Turtles that had once resembled mysterious yellow statues had now completely transformed into crystal-clear glazed color.

There was no longer any trace of the original Earth Spirit Turtles on the bodies of these ten glazed color Spirit Turtles.

Even their cultivation had silently broken through the shackles of the Earth Spirit Turtles' Tier 6 Life Essence while they slept.

Although the cultivation of these ten Spirit Turtles was still far inferior to the Azure Dragon, Xiao Kong, and Xiao Ling, the three beasts he had raised.

So far, after a full twenty thousand years, they had only grown to the Seventh-grade Peak.

Had they not relied on the Spirit Turtles' lifespan, which far surpassed that of Human Race Cultivators.

With merely Seventh-grade cultivation, they would likely have long since exhausted their lifespan and perished.
