William Carter had already been used by John Foster to seal the vengeful spirit of Xiang Yu. Although he had not yet fully utilized him, nor sealed the battle soul ghost general refined by Edward Parker within as well, John Foster, being naturally open-minded, did not care. In any case, whether William Carter lived or died was of no concern to him. Now that he had served his purpose, he simply kicked him aside.

When masters clash, it is hard to say whether victory comes from superior techniques or from the ability to adapt in the heat of battle. At this moment, John Foster secretly formed the Great Sun Wheel Seal, his true energy surging like a mighty river, the clear sky blazing with a proud sun—endless, inexhaustible, and unceasing.

Although Edward Parker was originally a true Daoist, after gathering the bones of birds and beasts from the mountains to forge his dharma body, he was no longer human nor demon, but something between a god and a ghost. Not only did he comprehend the mysteries of heaven and earth, but his true energy and spiritual power were also formidable. No matter how fiercely John Foster's Great Sun Purple Flame Force pressed in, it could never get within three feet of the old Daoist's body.

Both Edward Parker and John Foster knew the other's strength and dared not act rashly. But what neither of them expected was that the already chaotic and uncertain William Carter would suddenly let out a thunderous roar at this moment. He leapt high into the air, his whole body radiating a bright green light, as if undergoing another transformation.

Edward Parker’s greatest headache in cultivating the Doumu Mysterious Spirit Incantation was the heroic spirit of Xiang Yu that he had inadvertently summoned. This peerless overlord from over a thousand years ago, though long dead, remained undiminished in power. Even with Edward Parker's magical prowess, he could not subdue this fierce and unmatched ancient vengeful spirit. As a result, his progress in magic had always been slow. Today, John Foster used William Carter's virgin body to seal the millennia-old vengeful spirit of the Western Chu Overlord, which delighted Edward Parker greatly. As for John Foster alone, he was not afraid.

Seeing William Carter in such a strange state, Edward Parker feared that Xiang Yu's vengeful spirit would break free again. With a thought, the lingering spirits swirling around him formed dozens of black cords, which shot across the air to bind William Carter.

John Foster seized the opportunity, unleashing the full power of the Great Sun Wheel Seal. With one foot on the ground, he soared into the sky, charging straight at the floating Edward Parker.

“Xuanling flourishes, eternal longevity, Supreme Mystery Three-in-One, guard the true form, Five Elements return to place, myriad souls converge and transform—bind!”

Countless spirits, following Edward Parker's incantation, condensed into a vast net that covered the sky, descending upon John Foster. The Great Sun Purple Flame Force clashed head-on with Edward Parker's Myriad Souls Convergence Technique. The shockwaves within a radius of dozens of miles were like thunder, shaking the earth and mountains. In the distant Qing Shan village, old man Zhang was muttering nonstop: “Supreme Lord Laozi, Guanyin Bodhisattva, the merciful Tathagata Buddha, Kṣitigarbha Bodhisattva who saves the suffering.” He had no idea why the young Daoist had not returned, and why tonight's commotion was so much greater than usual.

“Could it be that the young Daoist is subduing demons? But why does it seem like the demon has subdued the Daoist instead?”

Leaving aside old man Zhang's wild speculations, William Carter was indeed in grave danger now. Entangled by Edward Parker's Nine Yin Soul-Binding Cords, the millennia-old overlord spirit of Xiang Yu, which was never truly restrained, suddenly surged in power. William Carter's bones and muscles seemed to be pulled by some force, growing larger, his muscles swelling like air-filled bladders. His skin, unable to withstand such force, was stretched thin and looked ready to burst at any moment, with purple veins bulging and twisting around his body like gnarled branches.

The once youthful William Carter was now shrouded in black energy, the outer layer of yin energy condensing into a form—a majestic giant eight feet tall, with a face full of bristling beard—revealing the true appearance of Xiang Yu, the Western Chu Overlord, trapped within William Carter's body.

Though a vague and ethereal vengeful spirit, the moment this Western Chu Overlord appeared, his presence was overwhelming. The Nine Yin Soul-Binding Cords that had been wrapping around him were sucked into William Carter's body like a whale swallowing the sea. With each spirit absorbed, Xiang Yu's form became clearer. Once all the surrounding spirits had been drawn into William Carter's body, the dense black energy wrapped him so tightly that not even air could pass through, and Xiang Yu's image had solidified, indistinguishable from a living person.

John Foster did not know the details of Edward Parker's Doumu Mysterious Spirit Incantation; he had only heard vague rumors. Meanwhile, Edward Parker assumed that William Carter was a secret weapon carefully prepared by John Foster, not realizing that John Foster had only just decided to drag this young Daoist in as a scapegoat.

Sensing danger, Edward Parker gathered power in his five fingers, and with a swish, a jade-green whip of light shot from his palm, lashing toward John Foster from afar. This jade-green whip was one of the ten great demonic weapons—the Azure Chi Cold Light Whip. It was said to have originally been an ice dragon sealed in the frigid depths of the North Sea, which Edward Parker had painstakingly refined into a magical treasure. Not only could it stir rivers and seas and control water, but it also carried a chill that would not melt for ten thousand years—its power was truly formidable, sinister, and evil.

Seeing the Azure Chi Cold Light Whip coming at him with a torrent of icy energy, John Foster shouted, “Staff, come!” The vajra staff, which had been knocked to the ground by William Carter, seemed to come alive, its golden light flashing as it flew from the ground into John Foster's hand.

With the vajra staff in hand, John Foster's momentum soared. Channeling the Great Sun Purple Flame Force, the staff shone with dazzling light, clashing fiercely with Edward Parker's Azure Chi Cold Light Whip.
