The sheer abundance of immortal essence was hundreds of times greater than that of the Three Kings Blessed Land!
Fang Yuan immediately took out a Green Jade Immortal Essence, pinched it between his fingers, and with a single thought, summoned the Fixed Immortal Travel Gu.
The Fixed Immortal Travel Gu looked like a beautifully crafted butterfly of pure green jade, exquisite and magnificent. It flew over slowly.
Fang Yuan's face turned pale. His entire body suddenly trembled violently, cold sweat poured out, and his vision went black. If he hadn't been gripping the edge of the bowl, he would have fallen flat on his face.
"Master, be careful! Your soul injuries are severe. You shouldn't casually summon an Immortal Gu, or you'll fall unconscious again," the Little Fox Spirit cried out, her voice anxious and her gaze full of concern.
"It's nothing. I know my limits." Fang Yuan gritted his teeth, waved his hand, and slowly opened his palm toward the Fixed Immortal Travel Gu.
Catching the scent of the Green Jade Immortal Essence, the Fixed Immortal Travel Gu lightly fluttered its wings, glided through the air, and landed on Fang Yuan's palm.
Then it lay down on the Immortal Essence and slowly began to suck.
The name "Fixed Immortal Travel Gu" contained the character for "Immortal" for a reason. Its food was Immortal Essence.
After a while, an entire Green Jade Immortal Essence was completely absorbed.
Gu Masters refine Gu, use Gu, and also raise Gu. Since Fang Yuan had refined it, he hadn't fed the Fixed Immortal Travel Gu at all.
He had slept for seven days and seven nights, leaving the Fixed Immortal Travel Gu starving. Its originally lustrous butterfly wings had already grown dim.
This was Fang Yuan's first time feeding it.
The Fixed Immortal Travel Gu, full and satisfied, fluttered its wings with contentment and flew up into the air. Its green glow radiated once more, scattering tiny, sparkling fragments with every wingbeat—an incredibly beautiful sight. The unique aura of an Immortal Gu emanated continuously.
"Feeding an Immortal Gu is costly. The Fixed Immortal Travel Gu must consume an entire Immortal Essence every time! Still, after this feeding, it won't need to be fed for another six years."
The higher a Gu's rank, the greater the cost to feed it, but the intervals between feedings also drastically lengthened.
Gu of the first and second ranks needed to be fed multiple times daily. By the fourth rank, feeding them once every few months was sufficient. A fifth-rank Gu could be fed once every year or two, and each feeding was a massive expense.
Having fed the Fixed Immortal Travel Gu, Fang Yuan ignored it, letting it fly freely around the Wandering Soul Palace. The only concern was that it didn't leave the Wandering Soul Mountain and didn't get killed by the shadow lightning.
Currently, Fang Yuan's aperture was still at the peak of the fourth rank. It couldn't accommodate an Immortal Gu in its full state.
The main reason he could store the Spring Autumn Cicada was that it was extremely weakened. Besides that, it was also because of the Life Gu.
Prioritizing matters, Fang Yuan was sure of his temporary safety once he understood his current situation. Now that the issue with the Fixed Immortal Travel Gu was resolved, he set to work on his soul injuries.
"Let's go. Little Fox Spirit, take me outside to find some Gallstones."
"Aye!" the Land Spirit immediately responded crisply. "Master, you should have done this sooner. Please, follow me."
The Little Fox Spirit led Fang Yuan. They arrived at the Wandering Soul Mountain.
The two walked across the rugged, uneven rocks. Fang Yuan's body swayed, causing the Land Spirit to look at him in concern. "Master, let me just teleport us there."
"Teleport? You have to conserve Immortal Essence!" Fang Yuan glared.
The Little Fox Spirit stuck out its tongue, startled by Fang Yuan. It couldn't help but think, 'This master really is imposing. Even injured, he still makes me scared.' "Master, there's a Gallstone here." After walking for a while, the Land Spirit stopped and pointed at a stone at their feet.
The stone looked like a human gallbladder, growing on the rock, its color mottled. If you weren't looking carefully, you'd just take it for an ordinary rock.
Fang Yuan quickly came over, crouched down, and smashed the Gallstone with his hand.
As soon as the Gallstone broke, a Gu immediately flew out, turned into a gray beam of light, and drilled into Fang Yuan's body.
Fang Yuan immediately felt a clarity in his mind. A new strength was added to his soul, and the ringing in his ears lessened considerably.
Wandering Soul Mountain could shake souls and was a place of death for all living creatures. It was only thanks to the Land Spirit's suppression that Fang Yuan could walk freely.
But Wandering Soul Mountain wasn't a purely deadly place.
The souls of living beings, shattered on the mountain, scattered and merged with the mountain itself. Over time, they formed Gallstones.
And within some Gallstones, there was the Valor Gu, which could strengthen a person's soul.
It was like how venomous snakes often live near antidotes. Everything competes, and the Great Dao maintains balance. Where there is life, there is death.
Wandering Soul Mountain seemed like a hopeless place of death, but it held a sliver of hope.
However, the Valor Gu could only exist for an instant. In that instant, it either died on its own or was shattered by the mountain again. Although the Land Spirit could suppress the mountain, the Gallstones couldn't be moved, they could only be gathered on the spot. Thus, Fang Yuan had to do everything personally, walking on the Wandering Soul Mountain.
