Bitter mussels swallow sand and gravel from the water, dissolving them and turning them into bitter water. Some people pry open their shells to obtain this bitter water and use it to brew wine. The resulting bitter mussel wine has a unique taste, both bitter and fragrant.
Once, Fang Yuan obtained a bitter mussel. He pried it open and used the bitter water to refine wine, and from this bitter wine he refined a Wine Worm.
Bitter mussels are already quite rare. A thousand-year bitter mussel is even rarer and is an excellent material for refining Immortal Gu.
The bitter mussel in Fang Yuan's hand was a thousand-year bitter mussel. Its shell was pitch-black with rings of white patterns, like tree rings. The black and white alternating was exceptionally striking.
Fang Yuan stared intently at the flame under the tortoise shell. As for the thousand-year bitter mussel in his hand, he didn't even look at it as he tossed it in.
Refining an Immortal Gu was of great importance, so naturally all immortal materials had to be inspected.
But Fang Yuan had already checked them many times beforehand, ensuring there were no mistakes with the materials.
Thus, while Fang Yuan was now refining the Gu, he didn't have to distract himself by checking the materials again. Instead, he focused solely on the intensity of the fire.
After the thousand-year bitter mussel was thrown in, the poison blood immediately stopped boiling, but the toxic smoke and fumes rolled and churned like a black python writhing inside.
A strong stench immediately emerged.
Fang Yuan didn't move, standing amidst the stench, carefully smelling it.
Although he was an Immortal Zombie and couldn't smell anything, he had an investigative killer move to assist, which could replace his sense of smell.
The stench was indescribably foul, so terrible that it made even Fang Yuan feel dizzy and want to vomit.
But Fang Yuan had to persist, because this stench was also one of the indicators of whether the Gu refining was going smoothly and whether the thousand-year bitter mussel had fully dissolved.
Soon. The thousand-year bitter mussel he had thrown in was completely dissolved. The black poison fog stopped churning. The poison blood began to boil again.
So Fang Yuan then threw in a second thousand-year bitter mussel. A third thousand-year bitter mussel...
After a total of twelve bitter mussels had dissolved, the poison fog reached its peak density, and the strong stench began to emit faint wisps of fragrance.
The expression on Fang Yuan's face grew even more solemn.
...
"Twin Ice Heart!!" Benduo Yi of the Hairy Folk shouted loudly.
Although he was only a Fifth Turn Gu Master, his attainment in Refinement Path was quite extraordinary, far beyond the norm. Thus, he had broad knowledge. As soon as Yu Muchun took out the immortal material, he called out its name.
Benduo Yi's face was full of shock.
An Ice Heart the size of a thumb was already an immortal material, but the Ice Heart that Yu Muchun now took out was as large as a washbasin!
Not only was it large, the key point was that this Ice Heart had a special appearance: it was composed of two heart-shaped pieces of white ice joined together.
This was a Twin Ice Heart, a hundred times more precious than an ordinary Ice Heart!
An ordinary Ice Heart was only a Sixth Turn immortal material, usable for refining Sixth Turn Immortal Gu. A Twin Ice Heart, however, was an immortal material for refining a Seventh Turn Immortal Gu.
"Such a precious immortal material was taken out first. It's clear that the Twin Ice Heart is not the main material for the Gu refining, but only an auxiliary ingredient. The master is truly formidable. I wonder what Gu he intends to refine." A look of worship shone in Benduo Yi's eyes.
At the same time, he also felt slightly relieved.
Since he used such a precious material, it showed that Master Yu Muchun was prepared and not acting on a whim.
But Benduo Yi also thought: Yu Muchun was actually here, in this wilderness, refining a precious Immortal Gu in plain view of everyone. Was this move displaying incompetence or exceptional skill?
It really left Benduo Yi at a loss for words.
The gentle breeze around them grew stronger and stronger, soon turning into howling gales. Tornadoes formed one after another.
The tornadoes were spaced apart, not interfering with each other, forming a forest of tornadoes.
Yu Muchun was in midair amidst the forest of tornadoes. The strong wind blew off his bronze mask, revealing an old face covered with dense fur.
Yu Muchun laughed heartily. His body shook, and the black robe covering him suddenly shattered. The pieces were quickly blown away by the wind, revealing his sturdy torso and his brown fur all over his body.
So it turned out that his true identity was the same as Benduo Yi's—he was also a Hairy Folk.
No wonder he had once instructed Benduo Yi.
Hairy Folk are a variant human race, different from ordinary humans. To be precise, they are two distinct races.
Even Fang Yuan did not know this identity of Yu Muchun.
