Yun Tianzun, hearing Hei Wu's words, felt a surge of killing intent in his heart. He coldly snorted, "Since that is the case, then let me see how much strength your Underworld possesses!"
As the words fell, Yun Tianzun flicked his finger, and a golden bead shot out, rapidly expanding to hundreds of feet in the void.
"Hmph, a mere bead, and you think you can harm me even a little? You must be dreaming!"
Hei Wu sneered upon seeing the golden bead, then a surge of black energy swept out, fiercely bombarding the golden bead.
The black energy collided with the golden energy, immediately producing a series of explosions.
"Hmm?"
Yun Tianzun's pupils contracted upon seeing this.
"As expected of the supreme existence of the Underworld in the ancient era."
"In this collision, I might not necessarily gain the upper hand."
"However, even so, we will not retreat half a step."
"Since your Underworld dares to provoke our Xuanhuang Holy Land, then today, it is the day of your Underworld's demise!" Zhou Yan also roared.
As the words fell, Zhou Yan moved again, and the golden energy madly condensed into the golden bead, once again surging towards the vast black mist.
The golden bead collided with the black mist, once again emitting a deafening roar.
However, at this moment, the golden bead had already dimmed, seemingly on the verge of shattering.
"Hmph, with just the two of you juniors, you think you can take my life? It's a fantasy!"
"I suggest you obediently surrender, otherwise, once I kill you both, I will then go after the Xuanhuang Holy Land. By then, you won't even have tears to cry!"
Hei Wu also sneered.
"Haha, good, since that's the case, then we won't be polite!"
"Senior Brother Zhou Yan, let's kill him together!"
Yun Tianzun also coldly shouted, and the golden bead shot out again, fiercely bombarding Hei Wu.
"Boom~"
Another earth-shattering boom, the golden energy and the black mist fiercely collided again.
Golden light shone, black mist rolled, and Yun Tianzun and Zhou Yan's bodies trembled violently.
"Hahaha, with just the two of you, you think you can oppose me?"
"Do you really think our Underworld has no strong individuals?"
Hei Wu sneered upon seeing this.
"Hmph, too much nonsense, die!"
Yun Tianzun's eyes filled with intense anger upon hearing Hei Wu's words.
"Boom~"
With a rumbling explosion, the black energy suddenly surged dozens of times, fiercely washing over Yun Tianzun.
Yun Tianzun's expression sank. He knew that this battle was likely to be disastrous.
"Hmph, even if you possess the peak strength of the ancient era, I am not weaker than you!"
Zhou Yan also said through gritted teeth upon seeing this.
As the words fell, Zhou Yan's eyes turned blood red. With a wave of his hand, a long sword radiating brilliant light appeared, fiercely attacking Hei Wu.
"Bang~"
The black mist and the long sword collided, immediately emitting an earth-shattering explosion, and wisps of black smoke emanated from it.
"Damn it, I can't break through your combined technique!"
Hei Wu's face turned extremely grim upon seeing this.
"Hmph, even if I can't break it, I can still hold you back, giving Senior Brother Zhou Yan enough time to escape."
"This time, I will absolutely not let you leave alive!"
Yun Tianzun couldn't help but mock upon seeing Hei Wu's expression change.
Seeing Yun Tianzun's demeanor, Hei Wu became even more enraged. He suddenly inhaled, drawing the golden bead into his mouth.
The next moment, Hei Wu's figure flashed again, transforming into a black shadow and attacking Zhou Yan.
Zhou Yan clenched his long sword, quickly charging forward, and battled Hei Wu.
"Hmph, with just you, you think you can stop me?" Hei Wu sneered upon seeing Zhou Yan's actions.
"Whoosh~"
Suddenly, Hei Wu's body moved, and in an instant, he disappeared from his original position.
Seeing Hei Wu's movement, Zhou Yan's heart tensed.
"Damn it, how can this guy be so fast?" Zhou Yan's expression shifted, his eyes fixed on where Hei Wu had disappeared.
The moment Hei Wu disappeared, he reappeared behind Zhou Yan, delivering a fierce punch towards Zhou Yan's head.
Sensing the sharp wind coming from behind, Zhou Yan's expression changed drastically.
"No, I can't let this beast ambush me, otherwise, I will surely lose!"
Zhou Yan's eyes flickered. He suddenly turned around, flicked his arm fiercely, and a ball of flame roared towards Hei Wu's fist.
An earth-shattering explosion occurred, the black energy and flames colliding, emitting a deafening sound.
However, Zhou Yan was merely sent flying backward, completely unharmed.
"Senior Brother Zhou Yan, are you alright?"
Yun Tianzun couldn't help but cry out upon seeing Zhou Yan being sent flying by a punch.
"Hmph, do you think I only have this much strength?"
"I'm telling you, I'm not afraid even if the two of you join forces."
"Today, I will let you know that opposing me leads only to death!"
Hei Wu also grinned ferociously upon seeing this.
"Heh, then I shall indeed wait and see!" Zhou Yan snorted coldly and continued to charge forward.
Yun Tianzun also waved his golden energy again, fiercely smashing it towards Hei Wu.
Seeing this, Hei Wu's lips curved into a mocking arc. His figure flickered, and he dodged the golden energy.
The next moment, he threw a punch, fiercely striking Zhou Yan's abdomen.
Yun Tianzun's pupils constricted upon seeing this, his face showing worry. However, a trace of determination flickered in his eyes.
"I'll risk it!"
Yun Tianzun took a deep breath, and the golden energy suddenly accelerated, fiercely striking Hei Wu's shoulder.
The next moment, Yun Tianzun and Zhou Yan's bodies were sent flying backward simultaneously.
However, during their flight, Yun Tianzun couldn't help but spit out a mouthful of blood, his face turning pale.
Although Hei Wu also spat out a mouthful of blood, he still stood arrogantly in the distance, looking down at the two.
"Heh, how is it? How much strength do you have left?"
"Your soul power, it's just about gone, isn't it?"
"You can't stop me!"
Hei Wu's lips curved into a chilling arc.
Yun Tianzun and Zhou Yan felt a surge of anger in their hearts upon hearing Hei Wu's words.
"Damn it, we will not give up, absolutely not give up!" Yun Tianzun said with firm eyes.
"Is that so? Then go die!"
Hei Wu's lips revealed an icy arc upon hearing this.
The next moment, his body trembled, and boundless black mist surged out from within him, enveloping the entire space.
