Having reached the realm, Fang Yuan immediately conceived an Immortal Gu killer move on the spot.
Since it was built upon the foundation of the "Ten Thousand Self" killer move, Fang Yuan named it "Ten Thousand Self — Second Form."
However, this killer move had only been roughly drafted. It was still a ways off from actual use.
Boom! Boom! Boom!
The two Eighth Transformation existences — Snow Bearded Old Ancestor and Dogtail Lifespan-Extending Mink Mao Liqiu — continuously assaulted the Reverse Flow River from both sides. The river churned with surging waves, reversing countless attacks, and the water level began to gradually drop.
Fang Yuan's actions had long since crossed these people's bottom lines. Moreover, his refusal to submit made Snow Bearded Old Ancestor and Mao Liqiu willing to expend tremendous effort to drain the Reverse Flow River entirely, all just to kill Fang Yuan.
Fang Yuan surveyed the river's surface and silently estimated: "At this rate, there's still quite a bit of time left."
His heart settled slightly.
The Reverse Flow River truly deserved its reputation as one of the great Secret Realms of heaven and earth. Even under the combined assault of two Eighth Transformation existences, it was only being consumed slowly.
Of course, there was another reason for this: neither Snow Beard nor Mao Liqiu was going all out.
They were wary of each other. What's more, Central Continent Gu Immortals like Bi Chentian and Wei Lingyang stood off to the side, watching for opportunities. These people were checking and guarding against one another — how could they possibly devote all their energy to Fang Yuan?
It was precisely this complicated situation that invisibly relieved much of the external pressure on Fang Yuan, allowing him to leisurely test his killing move.
First activation.
Fang Yuan was cautious.
The most essential component was the Persistence Immortal Gu, which continuously consumed Red Date Immortal Essence, allowing Fang Yuan to move freely within the Reverse Flow River, unrestricted by the Secret Realm's limitations.
After that, a large number of water-path mortal Gu rose one by one, flying up into the air around the enormous form of the Persistence Immortal Gu within his Immortal aperture, dancing ceaselessly up and down.
Before long, a great deal of water vapor rose, and faint blue light flickered within the mist.
However, the blue light quickly dissipated. Some of it even shifted from blue to red, and the originally cool water vapor rapidly heated up, growing hotter and hotter.
"Failed." Fang Yuan immediately stopped.
The scene before him was beyond his expectations. This was not what he had envisioned.
He cut off the flow of Immortal Essence. With a series of pops, a large number of water-path mortal Gu burst apart in midair, destroyed on the spot.
Fang Yuan calmed himself and kept thinking.
According to his design, the blue light should have grown brighter and the water vapor should have grown cooler. Why had red light appeared instead, with the temperature rising higher?
Fang Yuan ran calculations ceaselessly in his mind, and before long, thanks to his Wisdom Path attainment, he found the root of the problem.
It lay in the use of two water-path mortal Gu that were somewhat diametrically opposed in nature.
Fang Yuan immediately replaced one of them. Within the Reverse Flow River, he could open his Immortal aperture, and naturally he could also communicate with Treasure Yellow Heaven — acquiring some water-path mortal Gu was a trivial matter.
Having modified the entire Immortal Gu killer move, Fang Yuan began his second attempt at activation.
The Persistence Immortal Gu continued running as before.
The surrounding water-path mortal Gu rose in succession, revolving and dancing around it.
First came the billowing water vapor, then the blue light began to spread. After quickly passing through that phase, Fang Yuan began activating the Immortal Gu Wanlan.
Sixth Transformation force-path Immortal Gu Wanlan.
This was the second core of the entire killer move.
The first core was, of course, none other than the Seventh Transformation Persistence Immortal Gu.
Fang Yuan was cautious.
Activating Wanlan on top of already running the Persistence Immortal Gu was a highly risky endeavor. If the two were not harmonized properly, they would interfere with and even damage each other, potentially resulting in the destruction of one or both Immortal Gu.
Testing an Immortal Gu killer move was not only risky for the Gu Immortal — it was equally dangerous for the mortal and Immortal Gu involved. In fact, because Immortal Gu themselves contained fragments of the Great Dao, any backlash would cause even more severe damage.
Fang Yuan's caution quickly paid off — in the sense that he ran into trouble.
Although the Wanlan Immortal Gu was gradually being activated, the profound power it emitted refused to integrate into the broader framework.
"Where did the problem arise?"
Fang Yuan stopped.
Another large batch of water-path mortal Gu were destroyed.
Testing an Immortal Gu killer move demanded this kind of sacrifice. A complete and effective Immortal Gu killer move, from conception to testing, required the Gu Immortal to expend enormous amounts of energy and resources.
Outside, the attacks came in an unending wave, but Fang Yuan paid them no heed. He possessed the Supreme Immortal Body, and his mind was lively and agile, thoughts springing forth one after another.
Coupled with his attainment as a Wisdom Path Grandmaster — his Wisdom Path Dao marks and Wisdom Path methods — they all drove his calculations forward at breathtaking speed.
This time was even faster than the last!
