In the valley, evil spirit permeates the air, and true energy runs rampant.
While Su Chen was practicing, the battle between Zi Chen and others and the Black Dragon Demon King also reached a critical moment.
Dozens of powerful monsters under the Black Dragon Demon King had died in the hands of Zi Chen and others.
The valley was littered with corpses, filled with a strong smell of blood.
And that bloody smell made the Black Dragon Demon King extremely angry, his eyes were extremely red, full of monstrous murderous intent, and black divine lights intertwined, constantly intertwining towards Zi Chen and others.
Seeing that Zi Chen and the others were already at a disadvantage.
It is true that the Black Dragon Demon King's strength is too terrifying. Not only has his cultivation reached the peak of the Demon King, he is also good at several powerful demon powers.
What made Zi Chen's eyes become more solemn was that she had noticed that there were several powerful auras around her that were not weaker than the Black Dragon Demon King, and they were constantly approaching.
Those are several demon kings from the Black Dragon Mountains!
They were all alarmed by the fluctuations of the battle here, and came here one after another.
"We must fight quickly, otherwise it will be difficult for us to leave when all the demon kings arrive!"
Zi Chen said with serious eyes.
"yes!"
The four disciples of the Wuliang Sword Sect all nodded at the same time, with determination in their eyes.
Work hard!
boom!
But at this moment, above the void, a figure as terrifying as the sun emerged.
The unparalleled sharp sword light seemed to split the heaven and the earth, containing terrifying evil energy, and it directly killed those demon kings.
"Damn it! Chen Zhen, what are you going to do?"
"The Black Dragon Ancient City and the Black Dragon Mountain Range are not in conflict with each other. Do you want to start a war?"
"Chen Zhen, the Demon Emperor will not let you go!"
From the mouths of those demon kings, monstrous roars came out.
Boom!
However, the figure in the void seemed to have no intention of responding at all. The unparalleled sword light fell, accompanied by screams, blood filled the air, and the earth rumbled.
Those demon kings had almost no resistance and died under that terrifying sword light!
"That's...Martial Emperor?!"
A disciple of the Wuliang Sword Sect exclaimed.
"Martial Emperor? Could it be... that he is the city lord of Black Dragon Ancient City? It seems we are saved!"
Several other disciples also said in surprise and joy.
"Don't let your guard down, I'm afraid he's coming with bad intentions!"
Zi Chen's eyes flashed with sharpness, and he smashed a demonic light in front of him with his sword, and then he stepped back.
Whoosh!
The figure in the void, after killing several demon kings, ran straight to the valley without any hesitation, and appeared above the valley in an instant.
It was a middle-aged man wearing black armor, with a majestic face, and filled with evil aura. He stood in the void, feeling oppressed by the vast power of heaven and earth.
It is the lord of Black Dragon Ancient City, Chen Zhen!
"Chen Zhen, you dare to kill me, the Demon King of the Black Dragon Mountain Range. Aren't you afraid of the Demon King's revenge?"
The Black Dragon Demon King had a solemn look in his eyes, staring at Chen Zhen and roaring.
It didn't expect that Chen Zhen would dare to come to the Black Dragon Mountain Range.
"Demon Emperor? I'm afraid he can no longer protect himself at this moment! You evil beasts have been entrenched in the Black Dragon Mountains for many years. Do you really think that I dare not kill you? Just suffer death!"
Chen Zhen's eyes were extremely sharp, staring at the Black Dragon Demon King, full of killing intent.
He came after Su Chen.
After sensing that Su Chen had entered the Black Dragon Mountains, he decided very decisively to kill all the demon kings in the Black Dragon Mountains.
There are countless natural and earthly treasures in the Black Dragon Mountains, and there are even legendary spirit stone mines, which Chen Zhen has long coveted.
"What?! You're talking nonsense. The Demon Emperor has unparalleled combat power. If it weren't for his kindness, you would have been killed long ago! Chen Zhen, do you want to die?"
The black dragon demon king roared angrily.
He was shocked and angry.
It has been decades, and Chen Zhen has not dared to step into the Black Dragon Mountains.
Now that he dares to come to the Black Dragon Mountains and massacre the demon clan, he must have something to rely on. Could it be that something happened to the Demon Emperor?
"Demon Emperor?"
Zi Chen and others were also shocked. They had never heard of the existence of the Demon Emperor in the Black Dragon Mountains. It seemed that the Black Dragon Mountains contained many secrets.
"You evil beast, please die!"
Chen Zhen sneered and said, as if he was too lazy to talk to the Black Dragon Demon King, and a Yanyue Sword filled with endless evil energy appeared in his palm.
boom!
Then, his whole body's true energy surged, and the Yanyue Sword burst out with unparalleled blazing light, and fell in the air towards the Black Dragon Demon King.
"Chen Zhen, do you really think I'm afraid of you?"
The Black Dragon Demon King roared angrily and rushed forward in the air.
The ferocity in his heart was also aroused.
Boom!
However, Chen Zhen was the Martial Emperor after all, and he was extremely powerful. That sword contained the vast power of heaven and earth, cutting through the demonic light that filled the sky, and directly chopped down the Black Dragon Demon King from the void.
Below, the earth shook, the mountains shook, and rocks exploded.
Several of the indestructible scales on the Black Dragon Demon King's body were instantly chopped off, and the flesh and blood were blurred. It let out an earth-shattering roar and charged forward again.
But anyone can see that the Black Dragon Demon King cannot last long in Chen Zhen's hands.
"Sister, what should we do now?"
Several disciples of Wuliang Sword Sect looked at Zi Chen and asked.
