Gu Qingfeng suddenly extended his fair and powerful hand into the distorted space.
When he withdrew his hand again, he was holding a yellowed ancient tome.
On the cover of the tome were inscribed five large characters: "Single-Character Moon-Illuminating Sword."
Gu Qingfeng was slightly surprised. The Single-Character Moon-Illuminating Sword? What connection did this name have with the Single-Character Sun-Burning Sword?
Driven by curiosity, Gu Qingfeng couldn't resist flipping through the pages.
At the same time...
Hundreds of miles away from Wutong County, in a mountain forest, Li Qianren had just finished dealing with the Wild Dog Daoist of the Blood Demon Cult. His robes were spotless, and in his hand, he held a bloodied dog's head, his expression cold and stern.
Suddenly, Li Qianren's expression changed. His gloomy eyes fixed on the direction of the Demon Suppression Bureau.
"How is this possible? The spatial barrier I set was broken! Has something happened in the third layer of the Demon Suppression Prison? No! The Single-Character Moon-Illuminating Sword! And the Blood Divine Son!" Li Qianren's face turned frantic. He glanced at the dog's head in his hand and instantly understood the cause and effect.
No wonder the Blood Demon Cult's demons had been acting so strangely these past few days. It truly was a diversionary tactic!
They had fallen into a trap!
Li Qianren's heart was filled with anxiety, and his expression turned exceptionally grim. With a sudden burst of strength, he stomped the ground, creating a deep crater. Using the rebound force, he soared into the air and flew toward Wutong County.
Compared to the Blood Divine Son, he was more worried about the Single-Character Moon-Illuminating Sword. The Blood Divine Son was bound by hundreds of restraining chains, and the level of those restraints was such that even several innate masters working together would need days to break them.
The Single-Character Moon-Illuminating Sword, however, was different. The spatial barrier he had set was only meant to conceal it, but it was fragile. After all, spatial power was extremely profound, difficult for mortals to control. That Li Qianren could even use it was a testament to his extraordinary talent, let alone the quality of the barrier.
As he flew, his mind raced, piecing together past clues.
He recalled the mysterious innate master of the Blood Demon Cult who had appeared in the outskirts of Wutong County, combining the Bone Demon Flame with the Single-Character Sun-Burning Sword to destroy a mountain peak as a show of force.
At the time, Li Qianren had seen through the scheme, realizing that the man's true target was the Single-Character Moon-Illuminating Sword. So, he deliberately avoided paying attention to the sword's hiding place, and sure enough, the man eventually disappeared.
But now, after so much time had passed, that man had actually found the Single-Character Moon-Illuminating Sword!
Damn it!
I had seen through his plan and avoided looking at the sword's hiding place. How did he manage to discover it?
Suddenly, Li Qianren realized: when you can't find something anywhere, and there's one forbidden area no one is allowed to enter, even a fool would guess that the thing is in the forbidden area.
And that forbidden area was naturally the Demon Suppression Prison.
Outsmarting himself had led to his downfall!
......
After finishing the Single-Character Moon-Illuminating Sword, Gu Qingfeng suddenly understood. This martial technique was actually a counterpart to the Single-Character Sun-Burning Sword. Together, they could form a heaven-grade martial technique: the Cross Netherflame Sword!
The nature of the Single-Character Moon-Illuminating Sword was completely opposite to that of the Single-Character Sun-Burning Sword. If the Single-Character Sun-Burning Sword used yang fire, then the Single-Character Moon-Illuminating Sword used yin fire.
What was yin fire?
It was the opposite of the scorching nature of ordinary fire. While regular flames raised temperatures, yin fire did the opposite, lowering them.
The Single-Character Moon-Illuminating Sword was even more powerful, reaching the mid-level of earth-grade.
The only regret was that these two sword techniques were missing the most crucial part, preventing them from forming a heaven-grade martial technique.
That crucial part was the fusion of yin and yang.
When the scorching yang fire and the icy yin fire combined, the fusion of yin and yang would produce a tremendous energy reaction, and this energy was the key to the heaven-grade martial technique.
Seeing this, Gu Qingfeng suddenly had a flash of inspiration. Although the method for fusing yin and yang was missing, the essence was the fusion of yin fire and yang fire—essentially, the fusion of flames. Didn't that mean he could use his flame control talent to forcibly merge the two, without needing the method?
Gu Qingfeng grew slightly excited at the thought, but the specifics would require experimentation. Before that, he needed to find a source of yin fire.
After storing the Single-Character Moon-Illuminating Sword, Gu Qingfeng used Shadow Shifting to leave the Demon Suppression Prison. The commotion from his earlier fight with the fox spirit had already alerted some demon-slaying envoys.
As soon as Gu Qingfeng left, a brilliant beam of light shot out from the Demon Suppression Bureau, tearing through the darkness and piercing the sky.
For a moment, the entire Demon Suppression Bureau was as bright as day.
It was the Demon-Revealing Mirror, sensing the presence of the Blood Divine Son, issuing a warning.
As this beam of light appeared, similar beams shot out from the Demon Suppression Bureaus in the north, south, west, and center of the Great Yan Dynasty, resonating with the one from Wutong County.
At that moment, countless demon-slaying envoys were awakened. Seeing the light from the Demon-Revealing Mirror, they all understood the reason: it was a sign that the Blood Divine Son had been taken.
Immediately, the headquarters of the Great Yan Dynasty's Demon Suppression Bureau began issuing urgent orders, mobilizing countless demon-slaying envoys to prevent the revival of the Blood Demon.
Meanwhile, Gu Qingfeng, the mastermind behind it all, was enjoying a gift from the Outer Realm Demon.
Originally, he had sworn an oath to the Demon Suppression Prison's third layer to devour the Blood Divine Son, as demanded by the Pú Demon. But now, Gu Qingfeng had broken that oath.
He hadn't devoured the Blood Divine Son; instead, he had taken it out.
Of course, this was all intentional on Gu Qingfeng's part.
When Gu Qingfeng saw the Demon-Revealing Mirror shining brightly, he finally understood why the Pú Demon had repeatedly emphasized devouring the Blood Divine Son rather than taking it out.
It turned out that the Blood Divine Son was monitored by the Demon-Revealing Mirror. Once the barrier isolating its aura was broken and it left the Demon Suppression Prison, the mirror would sound the alarm.
But Gu Qingfeng had no time to dwell on this now.
The thread of the Demon Blood Oath wrapped around him began to move!
At the other end of the thread, connected to the void, there seemed to be a supreme and almighty being. With an indifferent gaze, it watched Gu Qingfeng, holding the thread in its hand.
