Let us turn back the clock, to not long ago.
The Heaven Overseeing Tower became ethereal, floating above the head of the Spectral Soul Demon Venerable. At this moment, the Spectral Soul Demon Venerable's hundreds of thick, pitch-black arms had shrunk severely, becoming dry, thin, and elongated.
With his help, the Ten Extreme Immortal Zombie Lifeless Grand Formation changed dramatically, and the spreading dark clouds quickly gathered towards the center.
In the center of the dark clouds, a sphere could be faintly seen, slowly rotating, radiating fourteen kinds of brilliant light.
Seeing this, the Heaven Overseeing Tower Master was greatly alarmed and quickly ordered, "Cut off these arms!"
The Heaven Overseeing Tower shot down like a sharp shuttle, carving a blinding rainbow of light through the air. Wherever the rainbow passed, the Spectral Soul Demon Venerable's arms were all severed.
"Ying Wu Xie, go deal with the Heavenly Court Gu Immortal immediately!" Immortal Zombie Bo Qing hurriedly shouted.
For them to deal with Fang Yuan and the others, it was like reaching into a bag to take something.
But due to various startling changes, they were interrupted several times.
Ying Wu Xie gritted his teeth, unwilling to leave like this: "Hold on, let me put Fang Yuan to sleep first."
So saying, he activated an Eighth Transformation level immortal killer move, Soul Luring Dream.
Fang Yuan had no place to dodge and was drawn into the dream.
A lakeside pavilion, the sound of the qin flowing melodiously.
Fang Yuan once again saw the Star Constellation Immortal Venerable.
Dream Dissection! Dream Dissection! Dream Dissection! Dream Dissection! Dream Dissection! Dream Dissection!
Fang Yuan hastily executed the Dream Path killer move, but the dream remained unmoving, at most causing a transparent ripple in his vision.
His Dream Dissection, although it counteracted dreams, was still only at the Sixth Transformation level. In contrast, the killer move Ying Wu Xie was activating had reached the Eighth Transformation.
The gap between the two was too large, causing Fang Yuan to be unable to unravel the dream.
Instantly, Fang Yuan's heart sank to the abyss.
The qin melody meandered a thousand turns, and the Star Constellation Immortal Venerable smiled faintly at Fang Yuan, opening her mouth to chant softly.
Fang Yuan, however, had a wry smile on his face, knowing in his heart that he had already lost this time!
Deeply trapped in the dream, his only method of dream dissolution. Declared a failure, Fang Yuan had no way to turn the tables.
But at this moment, the Star Constellation Immortal Venerable's chanting once again reached his ears.
The song is sparse. Heroes fall, unable to resist the vicissitudes of fate. Broken swords buried in sand, the rise and fall of millennia, the endless rolling of the River of Time. Sorrow… Endless deep nights, long soul dreams, where to find an abode of peace? Things change and hearts move over many springs and autumns. Only the vastness of heaven's will.
Once again, a mysterious surge of information flowed in Fang Yuan's heart.
Fang Yuan's soul, trapped in the dream, suddenly trembled violently!
"Things change and hearts move over many springs and autumns. Only the vastness of heaven's will!" At this moment, he finally understood the meaning of the last line of the poem.
So it was that the mysterious Seventh Transformation Immortal Gu he had obtained from Immortal Zombie Bo Qing was the Soul Exchange Immortal Gu!
Back then, Mo Yao, for her beloved Bo Qing, worried that he would fail his tribulation, decided to use this Soul Exchange Immortal Gu at the critical moment to swap their souls, hoping to hoodwink the heavens and save her beloved Bo Qing.
Bo Qing also wanted to use Mo Yao to help himself pass the tribulation, but feared that the calamity might affect his own will. So he simply permanently transferred this Immortal Gu to Mo Yao, rather than just lending it.
Therefore, the Soul Exchange Immortal Gu was refined by Mo Yao and filled with Mo Yao's will.
Afterwards, Fang Yuan, using the Wisdom Light Halo and Mo Yao's false intent, created a Gu formation. While stabilizing the Immortal Gu he had tricked out, he slowly refined them.
Because they were all of Mo Yao's will, the Soul Exchange Immortal Gu was the first to be successfully refined by Fang Yuan. The other Sword Path Immortal Gu, being filled with Bo Qing's will, were delayed and not successfully refined before the Yi Tian Mountain battle, still remaining in the Fox Immortal Blessed Land.
Following the instructions from the last line of the poem, Fang Yuan needed to extricate himself now; Dream Dissection was no longer feasible. He had to use this Soul Exchange Immortal Gu to swap souls with Ying Wu Xie!
Of course, it was not that simple.
The information flowing in Fang Yuan's heart contained a set of an Immortal killer move. This killer move had not only the Seventh Transformation Soul Exchange Immortal Gu as its core, but also the Attitude Immortal Gu, the Riddle Solving Immortal Gu, and many Mortal Gu of Dream Path, Soul Path, and others.
Fang Yuan hesitated for a brief moment, then decided to go ahead!
His previous successful experience let Fang Yuan know that the reliability of this information was extremely high.
The most critical point was that he had no other way.
At this moment, Fang Yuan was at the end of his rope. His opponent was the Spectral Soul Demon Venerable; with his current foundation and abilities, he simply could not shake him.
Only by following this instruction could he have the slightest hope of victory.
So, he activated the Immortal killer move.
