The flying dagger left its hand with extreme speed.
The other demons had no time to react before they were pierced through their heads, quickly disintegrating into countless small pieces that drifted in the air.
In a flash, the flying dagger also reached Xu Jiu.
Seeing the fate of his companions, Xu Jiu knew that Tang Yifeng's flying dagger was incredibly powerful. He absolutely could not hold back, or he would end up headless.
He hurriedly extended his hand, casting spells and drawing a circle in the air. A black ripple instantly appeared in the center of the circle, and a chilling aura emanated from the black hole.
Just then, Tang Yifeng's dagger arrived beside him.
The previously unstoppable flying dagger, upon nearing Xu Jiu, instantly changed direction, drawn by the black hole before him, unable to harm him.
"Oh?" Tang Yifeng showed a hint of interest upon seeing this.
His flying dagger was not something anyone could dodge. Xu Jiu's black hole seemed to have some substance.
After blocking Tang Yifeng's flying dagger, Xu Jiu did not stop.
Instead, he grabbed his own arm, then forcibly twisted off half of it, throwing it into the black hole. Ignoring the wound that was still bleeding, he looked at the black hole not far away and began a strange chant.
Since the people from the Five Great Immortal Mountains had discovered them, he had no need to hold back.
After all, he had never said he was alone.
As Xu Jiu's chant continued, the black hole expanded outwards, and an aura of world-ending destruction instantly emanated from it. A colossal pressure swept in all directions, blowing the fallen snow.
Su Xi and Tang Yifeng were not close to each other, but under this pressure, they felt a sense of weakness, like being in the ocean facing monstrous waves and feeling powerless.
Facing the immense pressure, Tang Yifeng did not retreat but chose to resist. Every inch of muscle on his face trembled, and the sword on his body began to vibrate.
"Nascent Soul stage pressure?" Tang Yifeng looked at the black hole, his expression serious for the first time.
Although he was confident, he was not blindly arrogant.
Most of the time, attempting to challenge those of a higher cultivation realm ended in death. Those who survived were few, let alone achieving victory against a stronger opponent.
However, soon, a look of realization appeared on his face.
This was the secret realm of the Five Great Immortal Mountains. Although he didn't know how the demons had snuck in, it was impossible for a Nascent Soul stage cultivator to evade layers of formations and enter undetected.
Therefore, even if the pressure from the black hole was immense, it could not possibly be a true manifestation.
Most likely, only a wisp of a remnant soul was being transmitted from the black hole. If it was only a remnant soul, then he had confidence he could fight.
Having figured this out, Tang Yifeng's fighting spirit immediately flared. Gripping his sword tightly, he unhesitatingly unleashed the ultimate technique of Mount Shu—Ten Thousand Swords Returning to the Origin.
Tang Yifeng's Golden Core stage cultivation made the use of this technique even more potent than Wu Yufeng's.
The flying swords covering the sky, like waves in the ocean, surged forward one after another, cutting towards the black hole. Although the fierce sword energy was absorbed by the black hole for the most part, some still fell around it, preventing the black hole from expanding further.
With the expansion of the black hole suppressed, an unwilling roar of extreme displeasure emanated from within.
Seeing that Tang Yifeng had managed to stop his summoning, Xu Jiu's face instantly turned grim. He knew that if he couldn't summon the demonic creature, his fate today would be dire.
Thus, a ferocious expression appeared on his face. He picked up a weapon from the ground, chopped off his own thigh, and threw it into the black hole.
Using his body's flesh and blood as a sacrifice once more, he instantly accelerated the expansion of the black hole. In the blink of an eye, the opening was fully enlarged.
With a "boom," a centipede at least ten meters long crawled out of the black hole along its maw.
This centipede was entirely crimson and gold, and its pair of red eyes sent shivers down one's spine.
Tang Yifeng's gaze sharpened, and his flying sword struck the crimson-gold centipede. However, apart from a clanging sound and a white scratch, it caused no damage.
Seeing that his attack could not penetrate the crimson-gold centipede's defense, Tang Yifeng was not surprised. If it were that easy, Xu Jiu wouldn't have gone to such lengths to summon the centipede.
He took out his wine gourd, took a hearty swig, mixed it with his magic power, and then spat the wine out.
The flying swords, now imbued with the wine, instantly emitted a bright white light and a fierce buzzing sound.
"Whoosh!"
"Whoosh!"
"Whoosh!"
One by one, the flying swords struck the crimson-gold centipede again, their might far exceeding their previous attacks.
The crimson-gold centipede seemed to recognize the extraordinary power of the flying swords and dared not withstand them with its body. It reared up, emitting a series of golden lights.
In the golden light, those imposing flying swords suddenly lost their direction, like compasses without a magnetic field. They flew erratically, unable to approach the crimson-gold centipede.
Seeing the crimson-gold centipede gaining the upper hand, a triumphant smile spread across Xu Jiu's face.
Today, by risking serious injury, he only needed to kill Tang Yifeng, this peerless genius of the Five Great Immortal Mountains. The elders of the demon race would then help him reshape his physical body. After complete demonization, he would even have room for advancement.
Tang Yifeng felt that the crimson-gold centipede was difficult to deal with but had no intention of giving up.
He knew the crimson-gold centipede was powerful, but he had confirmed that the one before him was merely a remnant soul. The actual body of the crimson-gold centipede had not been transmitted, so he still had a chance.
However, he needed time to observe the crimson-gold centipede's weakness to deliver a fatal blow.
Thus, his gaze shifted towards Su Xi's direction, and he roared, "Why aren't you coming out yet? If something happens to me, do you think you can escape?"
Hearing Tang Yifeng's words, Xu Jiu instinctively glanced over, then his expression turned disdainful. "Bluffing. Do you really think someone will come to help you just because of that?"
Xu Jiu continuously channeled his magic power, wanting to eliminate Tang Yifeng as quickly as possible.
But suddenly, he heard a sigh of helplessness in his ear, and then he felt a chill in his chest, followed by intense pain spreading through his body.
He looked down in disbelief and saw a large bloody hole in his chest, from which blood was continuously flowing.
"What is this?" Xu Jiu looked at Su Xi behind him, his forehead covered in black lines.
Su Xi was also feeling helpless. However, since she had been discovered, she naturally wouldn't refuse to help. After all, she valued her own life.
Her hiding spot was difficult to find, but it couldn't guarantee she wouldn't encounter the crimson-gold centipede. She didn't have the confidence to evade such a formidable monster.
