The Secret of Whale Rubber

After finishing his cultivation, Li Long sat on a rock beside the spring, the Dragon Emperor Rod laid across his knees as his fingers slowly brushed over its surface.

The Icefire Dragon Emperor slumbered quietly within the rod. Crimson and blue interwoven scale patterns faintly flowed across the dark gold background, like a young beast taking deep breaths, each pulse steadier and stronger than the last.

He closed his eyes and thought for a while before stowing the Dragon Emperor Rod behind his waist. Then he rose and walked over to the stone table where Qian Yue usually processed medicinal herbs.

Her notebook recording the reactions of mineral samples from that day still lay open on the tabletop, with a half-used charcoal pencil beside it.

Li Long took a blank sheet of stationery from his storage ring and spread it across the table. Picking up the charcoal pencil, he wrote a brief message.

In the letter, he wrote that while traveling, he had happened upon a fragment of an ancient text. It mentioned a gelatinous substance that condensed inside certain sea beasts in the depths of the East Sea. After being melted at high temperature and consumed, it could greatly strengthen the toughness and capacity of the body's meridians.

He recalled that he had begun using this material to assist his body tempering back when he was stationed at the Notting City branch hall. The material he had used then was of a lower age and had limited effects. Later, with resource support from Spirit City, he had gradually used materials of greater age and confirmed that it truly raised the upper limit of Soul Ring absorption.

The proper method was to melt it into liquid at high temperature before consuming it. That way, it would not produce impure thoughts.
