Suddenly, a breeze blew, and then the black hole began to spew hot magma.

The ground began to collapse and begin to sink downward, and the three of them were stunned when they saw this scene, "Brother Cangqiong, this..." Yu Qian looked at the sky with puzzled eyes.

The sky shook his head, "This phenomenon is also the first time I've seen it. ”

Cai Tianyi looked at Yu Qian worriedly, and then opened his mouth, "Senior brother... Could it be the demon down there, the ghost? ”

The two of them suddenly appeared to be suddenly enlightened, and then, the sky said loudly: "Yu Qian, Tianyi, and this girl, I'm afraid the demon below is not dead yet, let's give him another force." ”

As soon as the words of the sky fell, the ground rumbled again, and a strange sound followed, followed by a clicking sound.

The landslide and ground cracked visible to the naked eye, shaking the four people apart.

The surrounding scenery began to change dramatically, and the four of them began to descend all the way down the narrow passage, and the further down they went, the temperature of the ground became higher and higher, and the light began to dim. From time to time, magma fell from the sky, and the four of them had to hide to the side to avoid it.

"It seems to be getting more and more dangerous here." Yu Qian said cautiously.

"Looks like we'll have to be careful, this should be the place where the demon just got out of trouble." Cai Tianyi clenched the weapon in his hand with a solemn expression.

After walking for about half an hour, they finally came to a huge space. The air here is so turbid that it is even difficult to breathe.

When the sky looked up, there was a huge crater above, and you could see the magma gushing, and you could even hear roars and explosions.

"The devil is there!" Yu Qian suddenly pointed to the distance and shouted loudly.

The four of them saw a huge figure standing on the edge of the crater, spitting out flames and magma. It was a huge monster, about ten meters tall, covered in hard iron and its eyes glowing green.

"You're just trying to get me back in? Firmament, you're there, too. Scold... Scold... Heh" The monster's deep voice sounded, making people feel a sense of oppression.

"We are here to deal with you monster, for the sake of human life, for the safety of human home and country, we can't let you out." The sky rose to the occasion, the sword in his hand slicing through the air and slashing at the monster.

Instead of panicking, the monster rushed forward and blocked the attack of the sky with the iron rod.

"Looking for a fight!" Cai Tianyi screamed, jumped hard, and jumped on top of the monster's head. A moment later, his arm turned into a hammer and struck at the monster's head.

But the monster seemed indifferent, as if these attacks did not pose any threat to it at all. At the same time, Yu Qian also jumped up and attacked the monster's iron sheet with a sharp blade, but he couldn't cut into it at all.

All four of them felt a little brainless, trying to find out the monster's weaknesses, but always to no avail.

At this moment, a strong momentum spread from the ground, and a dark shadow appeared in front of them. It was a tall man, wrapped in black clothes, holding a long sword in his hand, and looking very fierce.

"Can you destroy it if you continue to fight like this?" The man muttered to himself as he wielded his sword.

With a roar of rage, the entire cavern seemed to be shaken. The monster also felt the pressure and began to retreat.

Seeing that the opportunity was not good, the man immediately attacked, and each slash carried great power, leaving the monster helpless.

The firmament looked at the man gratefully, but still asked suspiciously, "Who are you?" How did you get here? ”

The man took a deep look at the sky, and his expression became a little complicated.

"I'm a descendant of demon blood, and I'm only here to destroy the demons underneath. Leave me alone, get out of here. The man's tone was firm.

"We can't just leave you alone." Cai Tianyi said resolutely, "Let's go and destroy the demon down there." ”

The other three nodded their heads. Although their goal this time was to destroy the demon, they couldn't bear to watch the Demon Blood Descendant face such a terrifying enemy alone.

So, the four of them rushed towards the huge monster again and began a fierce duel.

Out of control, the battle became more and more intense, and finally, Yu Qian found an opportunity in a retreat, turned around, and inserted the sword into the demon's body in a later time, and the demon fell and disappeared in response. It took the Demon Blood Descendants and the Four to successfully destroy the monsters, but they also suffered varying degrees of damage.

Although the danger in this cave has been removed, they have not let their guard down, they are afraid that there are other dangers in the cave.

After a long time, they came out of the cave with a beautiful sight before their eyes. The sky here is so clear and sunny that people can't help but feel relaxed.

"Let's go." "There are still many unknown dangers waiting for us on the road ahead. ”

"Brother Firmament, do you want to come with us too?" Yu Qian looked at the sky in surprise and said.

Meng'er looked at Brother Cangqiong in front of her and echoed and said, "Yes, Brother Cangqiong, everything outside here feels so weird, we just came out and it wasn't like this, but now you can see that it has changed again." ”

The sky nodded, Yu Qian, and the other two did not persuade again.

When the four of them walked out of the cave, they found a strange wilderness in front of them. There is no vegetation here, only some strange rocks scattered on the ground. There was a hint of weirdness in the air that made people shudder.

The sky looked around, and his face was solemn. He knew that although this wilderness seemed quiet, danger could come at any time.

"Let's be careful, let's go that way." The sky motioned for everyone to walk into the distance. They walked slowly along a narrow path, constantly alerting them to movements.

Soon after, they came to the top of a hill and looked into the distance. I saw an ancient city in front of me, and the city walls were towering into the sky, majestic and magnificent. There are also some towers and gates around the city, which look very grand.

"Let's take a look over there." The sky pointed to the city in front of him and said.

The four of them began to march towards the city without encountering any obstacles. They passed through the gates and came into the city. The streets here are very narrow, and the houses on both sides are very old, some of them have even collapsed. There are few pedestrians on the street, and it seems a little deserted.

Meng'er looked around and saw that the city seemed to have been abandoned for a long time. "It looks like no one has been here for a long time." She said with a frown.

"yes, it looks very old." Yu Qian replied in a low voice.

Cai Tianyi began to notice the buildings around him. "There might be something useful in these old buildings, and we can look around first."

The four of them began to search the city, entering some abandoned buildings, and found that some parts of them had collapsed, but others looked relatively intact. They found some bizarre books and artifacts.

Before you know it, it's getting dark. They arrived at an inn where they were going to rest for the night. The innkeeper was an enthusiastic middle-aged man, and they learned from their conversation that the city had been controlled by the Demon King for a long time, and the people of the city had fled and become a dead city. And the Demon King's sphere of influence is not limited to this city, the whole world is under his threat.

Listening to the boss's words, the faces of the four of them showed worry. "Sure enough, this world has changed a lot, but that demon king, let's solve it by the way." The sky said.

The next morning, the four prepare to leave the city and continue their adventure. They passed through the gates and came into another vast wilderness. There is no life here, just some strange rocks and deserts.

As they progressed, they discovered mysterious ruins that spread across the wilderness as evidence of a lost civilization. These ruins contain some ancient technology and knowledge that will be very helpful in their adventures.

"It's changed too much." Meng'er sighed.

"Yes, but maybe we can find out why this world is starting to change through the Demon King this time." The sky nodded and said, "We have to keep exploring to discover more things." ”

They continued to move forward, and I had barely taken two steps when a huge humanoid monster stopped them in front of me, and the humanoid monster, still spitting out his words, said, "People... Food, food. ”

Meng'er waved her hand, rushed forward with a sword in her hand, and split the monster in half with a horizontal batch.

Two days later

They came to a mysterious place where a huge tower stood in front of them. The tower, which is tall and made of black rocks, looks very ancient and mysterious.

"This should be where the Demon King is." The firmament said in a solemn tone.

The four of them looked at each other, and then the sky shouted, "Let's go!" It should be inside."

The firmament stepped forward first, pushing open the tower's door with all his might. The door creaked open with a heavy clatter, and an eerie aura came from inside. They cautiously walked inside and found the interior of the tower spacious and ornate, with various precious works of art and weapons hanging on the walls.

On the top floor of the tower, they found the location of the Demon King. The Demon King is a huge black monster with red eyes and sharp teeth. He saw the four of them, and a flash of contempt and anger flashed in his eyes.

There are also four women with white hair and blue silk around the demon king, but the women at this moment are like puppets, their eyes are empty and bloodless.

"You tiny humans dare to trespass into my territory." The Demon King roared, "I'll let you know what the end of challenging me is, but before that, I'll let you meet these four of my slaves." ”

As soon as the words fell, the four women moved, fast and orderly, and rushed towards Yu Qian's four people.

Yu Qian looked at the four women, their movements were so fast, like puppets being controlled. There was no life in their eyes, as if they were soulless. Yu Qian couldn't help but feel a little sad in his heart, they were all innocent people, but now they were controlled by the demon king and became his slaves.

Yu Qian took a deep breath, pulled out his sword, and said to the three people next to him, "Senior brother, Meng'er, these people in the sky seem to be controlled by this demon king, what should I do?" ”

"I want to take a look around them," the sky responded.

Meng'er and Firmament, and Cai Tianyi also started to fight, and their swordsmanship was equally precise and fast. But even they will not be able to solve this battle in a short time.

Seeing that the battle was at a stalemate, Yu Qian suddenly thought that perhaps, he could try to use her healing power to awaken the consciousness of these four women. He tried to inject healing power into their bodies, but their movements suddenly slowed down, and some anger began to appear in their eyes.

Yu Qian continued to inject healing power, and she felt their bodies gradually recover, and their eyes became brighter and brighter. Their movements began to slow until finally, they stopped attacking, their eyes filled with surprise and gratitude.

Seeing this, Yu Qian breathed a sigh of relief. He knew that he had succeeded in awakening the consciousness of the four women, who were no longer slaves of the Demon King, but had gained freedom.

The Demon King looked at all this, his eyes full of surprise and anger. He couldn't believe that his slave would be saved by a small human. He roared angrily, wanting to control the four women again, but Yu Qian was ready, and he injected healing power into their bodies, making their consciousness more determined and no longer under the control of the demon king.
