Fang Yuan still had some time before he had to head to Starry Sky Grotto-Heaven. To make better use of this time, he had decided to focus on developing one of his immortal killer moves.
This killer move was somewhat different from ordinary immortal killer moves. Killer moves used the principle of employing a large number of Gu worms to create a new effect, or increasing the power of an Immortal Gu by adding Gu worms to amplify its effect.
There was another aspect to immortal killer moves, such as using immortal materials or secluded domains of heaven and earth. However, secluded domains of heaven and earth and immortal materials were not as flexible as Gu worms.
Gu Master cultivation had developed throughout history, and in every era, all kinds of strange methods and paths had appeared. Immortal killer moves were not limited to Gu worms; desolate beasts and Gu Immortals could also be used to refine immortal killer moves.
Four ancient desolate beasts were placed before Fang Yuan. Each of these beasts possessed rank seven battle strength, each of them had extremely dense strength path dao marks, and they let out unwilling roars.
Fang Yuan grabbed one of the ancient desolate beasts. This beast had the form of a huge crocodile, its skin was as tough as iron, and when Fang Yuan grabbed it, it let out a threatening roar before being beaten by a giant strength path hand.
The ancient desolate beasts quickly quieted down upon seeing their companion being beaten, and Fang Yuan began refining the ancient desolate beast Steel Chief Crocodile.
Fang Yuan had supreme grandmaster attainment in refinement path and great grandmaster attainment in strength path. He had conceived this method and improved it based on experimentation, making the possibility of failure nearly nonexistent.
The crocodile whimpered as a layer of dense qi enveloped it and pressed down on its bones and body until cracking sounds came from within. Fang Yuan waved his hand, and a strength path phantom identical to the Steel Chief Crocodile appeared.
The strength path phantom charged forward and devoured the helpless ancient desolate beast's body under Fang Yuan's control. Fang Yuan revealed a satisfied expression as the strength path phantom began to gain a trace of spirituality.
Fang Yuan continued controlling the refinement process while using numerous refinement path killer moves to push the process toward the result he desired.
After the refinement process ended, the Steel Chief Crocodile had become around thirty percent smaller, and its aura was no longer as powerful as that of an ancient desolate beast. However, Fang Yuan had expected this result. After all, he only possessed rank six Steel Chief Crocodile Strength Immortal Gu, not rank seven. And even if he possessed the rank seven Immortal Gu, it would not be suitable for him.
Fang Yuan stored the distinctive strength path phantom before repeating the process with the other ancient desolate beasts.
There was a monkey, a snake, and a water dragon hawk.
Two days later, the other ancient desolate beasts had been refined and turned into distinctive strength path phantoms with powerful auras comparable to rank six Gu Immortals. Each of these beasts possessed a trace of spirituality.
Fang Yuan immediately used the new immortal killer move after finishing.
Immortal killer move — Strength Path Beast Deities!
The strength path phantoms immediately transformed into misty humanoid forms, each of them having a vague appearance resembling Fang Yuan. One of the strength path phantoms moved and struck the wall of the room Fang Yuan was in.
Boom!
The wall shattered into dust, and Dang Hun Mountain shook for a moment. Even Little Hu Immortal appeared before Fang Yuan in panic.
"Master!… What was that? The entire Dang Hun Mountain shook!" Little Hu Immortal looked at the misty figures resembling Fang Yuan and felt dizzy.
"Not bad. There is still room for improvement if I raise the core Immortal Gu to rank seven, but for now, it is suitable for me…" Fang Yuan was somewhat satisfied with the results.
Fang Yuan had invested four ancient desolate beasts in the process to raise the battle strength of the strength path phantoms. He had also spent a great deal of time improving the refinement process through the endless inspiration provided by the light of wisdom.
The results were good, and the only reason Fang Yuan's satisfaction was limited was that this immortal killer move could not display its full power because its core Immortal Gu, All-Out Effort, was only rank six.
"At the basic level, the immortal killer move Strength Path Beast Deities gives the strength path phantoms peak rank six battle strength. But with the amplification of my strength path dao marks, the battle strength of each strength path phantom barely reaches rank seven."
The power of this killer move was extremely impressive and exceptional among rank six and rank seven Gu Immortals. But at rank eight, this killer move would become useless because of its terrifying cost.
In truth, in Fang Yuan's previous life, he had created a killer move called Emperor Yama. Thus, Strength Path Beast Deities was not much different from it.
Emperor Yama had given him important inspiration and reference for developing Strength Path Beast Deities, giving him a general direction to follow.
After finishing all the experiments and tests, Fang Yuan summarized and analyzed his experiences.
Fang Yuan expended his thoughts and spent a bead of green grape immortal essence to travel using Fixed Immortal Travel.
Jade light flashed, and within three breaths, Fang Yuan arrived at Starry Sky Grotto-Heaven.
Fang Yuan appeared outside a cave, and beside him was a dense, green and lush forest. The forest was located high on a mountain, and the moment Fang Yuan appeared, his aura leaked into the surrounding environment.
Fang Yuan was completely armored in a layer of liquid metal. When he raised his head toward the sky, he was greeted by the barking of three dogs.
Bark!… Bark!
Three desolate star hounds leapt down from the top of the hill toward Fang Yuan, who had appeared below the mountain. These hounds were as large as hills, and Fang Yuan's presence in their territory had aroused their ferocity.
The male attacked Fang Yuan ferociously, descending with overwhelming force that shook the surrounding forest, landing on the ground a hundred meters away from Fang Yuan.
Fang Yuan retreated slightly as a shadow slipped out of his body. With lightning speed, a human figure appeared before the desolate star hound. The human shadow transformed into a giant snake several times larger than the desolate star hound. With overwhelming constricting force, it coiled around the desolate star hound's body, crushing it until it lost consciousness.
The female desolate star hounds barked in fear at the giant snake. Fang Yuan moved to finish this, using two giant strength path hands to subdue the pack of desolate star hounds.
Fang Yuan placed the desolate beasts into his immortal aperture before heading toward the loophole he had deduced.
