What kind of supernatural power the Coffin Master Cheng Xin possessed, Yan Dongxu still hadn't figured it out.
The black energy she released was profound and terrifying, as if it could devour everything.
Yan Dongxu found that his own supernatural power was not sealed, but rather devoured and absorbed.
That was why he was bound here.
"Don't struggle, or you'll get hurt," Cheng Xin sipped her red wine, smiling sweetly at him as if admiring her prey.
"How did you know I was here?" Yan Dongxu asked.
"Heh heh heh, I admit White Moon's information gathering capability is strong, but don't forget that the last time they suffered a loss was because of our Death Coffin," she replied.
"You think we'll lose to them? Don't underestimate Death Coffin, it's a huge organization beyond your imagination," Cheng Xin rose and sat on the sofa, as if waiting for something.
Yan Dongxu found it suspicious, "What exactly are you up to?"
"Don't be in such a hurry, on such a wonderful night, having just you to serve me is not enough," Cheng Xin tilted her head slightly, looking out the window and smiled, "They're here!"
Yan Dongxu looked out and saw Zhou Quan arriving on his sword, shattering the floor-to-ceiling window of the presidential suite with a single strike.
"Well, you've made quite a mess of this nice room, but at least the bedroom is intact," Cheng Xin remarked with a smile.
"You vile woman! Die!" Zhou Quan clearly knew of Cheng Xin's existence.
As an elder of the Superhuman Alliance, how could he not be aware of the three Coffin Masters of Death Coffin?
However, seeing Cheng Xin here made Zhou Quan's heart skip a beat, fully aware of how formidable she was.
"Nine Suns Sword Art!" Zhou Quan roared, and the long sword in his hand radiated a golden glow like the blazing sun.
In an instant, Yan Dongxu felt the black energy enveloping him disperse, and he appeared beside Zhou Quan in a flash.
"It's a good thing you came, or I would have been ruined by this woman today," Yan Dongxu said with lingering fear.
"Tsk tsk tsk, starting off with such pure yang energy, are you not afraid I'll drain you dry?" Cheng Xin's eyes were alluring, and the black energy condensed into nine swaying black fox tails behind her.
A nine-tailed fox demon?
Yan Dongxu was greatly shocked, exclaiming that this was far more powerful than the Thousand-Faced Duke Chu Yuan's replicated foxes.
"Zhou Quan, do you think you can handle this?" he asked Zhou Quan.
"I don't know, let's try!" Zhou Quan was also unsure, as he felt the pure yang energy gathered on his sword being absorbed by Cheng Xin's black energy.
"A single elder can't deal with me. If all the old masters of the Alliance came together, perhaps they could restrain me," Cheng Xin's eyes shimmered with purple light as her terrifying black energy surged towards them.
"Break!" A blazing sword beam slashed through the dark energy, heading straight for Cheng Xin.
However, as the sword beam approached, it grew smaller and smaller until it disappeared completely.
Cheng Xin's body trembled and convulsed as she murmured in ecstasy, "Such powerful yang energy."
Yan Dongxu and Zhou Quan blinked, realizing that continuing the fight would only lead to them being drained dry.
The two exchanged a glance and turned to flee.
"Trying to run? When this lady's body hasn't even warmed up yet, you want to leave?" The insatiable Queen of the Dark Night Cheng Xin slowly extended her palm and whispered, "Black Night Ritual, Black Palace!"
In an instant, the sky above the city turned pitch-black.
This wasn't the darkness of night, but a profound blackness that devoured everything.
All the people in the city looked up at the sky, filled with immense dread.
This blackness was too ominous, as if the end of the world had arrived.
A massive black palace materialized in the sky, trapping Yan Dongxu and Zhou Quan inside.
"Damn it! Has this woman gone mad? Using her domain ability here is tantamount to declaring war on the Alliance!" Zhou Quan cursed without any fear.
Energy surged around Zhou Quan's body, making him seem like a descending deity as he unleashed a series of sword strikes against the black palace confining them.
The black palace cracked open, and Yan Dongxu used his spatial power to teleport them both out.
Fearing they would be ensnared again, he teleported several more times in quick succession.
Just when they thought they had escaped, they found themselves trapped inside the palace once more.
"Is this some kind of sorcery?" Even Yan Dongxu, a spatial power user, was baffled.
"No, it's a domain. We never actually left her domain," Zhou Quan's expression darkened, realizing he had underestimated Cheng Xin's strength.
"What exactly is her ability?" Yan Dongxu still couldn't discern the nature of that profound black energy.
"Darkness! Her ability is darkness! Now that the sky has darkened, her energy will increase manifold. The Dark Night Queen, Cheng Xin," Zhou Quan said gravely.
"I always thought so-called darkness wasn't that terrifying, but today, facing it for the first time, I realize I was wrong," Zhou Quan rarely appeared so solemn.
Yan Dongxu regretted involving his brother.
"Let me try. Can you strike a few more times?" Yan Dongxu asked.
Zhou Quan nodded and slashed out a few more sword beams.
In an instant, Yan Dongxu took Zhou Quan and burst out again, while simultaneously condensing his spatial power and unleashing it with a swing.
"Dimensional Slash!"
A terrifying spatial blade tore through the darkness.
This strike depleted all of Yan Dongxu's spatial energy.
He felt light-headed, his consciousness fading.
Suddenly, Zhou Quan stuffed a pill into his mouth.
A surge of warmth spread through his body, quickly restoring his clarity.
"Can you do that attack a few more times?" Zhou Quan asked excitedly.
"If you have more of those pills you gave me, I should be able to," Yan Dongxu replied, his energy restored after taking the pill.
"Heh heh, we have plenty of those!" Zhou Quan took out several more bottles, clearly well-supplied.
Yan Dongxu gulped down another bottle with great vigor.
Feeling like he was about to burst, he continuously condensed spatial blades in his hands, each over a thousand meters long.
"You vile woman, die! Grand Dimensional Slash!"
Whoosh!
Cheng Xin's domain of darkness was torn open by the massive spatial blade.
She coughed up a mouthful of fresh blood, her face etched with shock.
"You really have given me quite a few surprises!" she exclaimed.
Sensing a few auras had locked onto her position, likely the old masters from the Alliance headquarters, Cheng Xin said, "I'll play with you until here today. But I will drain you dry eventually!"
With a seductive smile, the Queen of the Dark Night Cheng Xin vanished into the blackness.
Unsatisfied, Yan Dongxu swung two more spatial blades towards where she had disappeared, but failed to strike her.
"Damn it!" he cursed, frustrated at being so helpless for the first time.
Suddenly, he noticed the iron-faced gentleman, Bei Xiao, standing by the shattered window of the presidential suite.
They exchanged glances from afar, with Yan Dongxu flashing a cruel smile, while Bei Xiao's expression turned sour before fleeing.
"Damn it, if I can't defeat a Coffin Master, how can I even beat you, a mere Ten Commanders member? Spatial Banishment!"
With spatial energy surging around him, Yan Dongxu roared and enveloped Bei Xiao in his spatial power.
