Chapter 884

Facing the powerful attacks of the group, the alien was finally defeated and killed. His fatal wound was at the space between his eyebrows, pierced by Wang Xian 'er's sword light.

The tall and big body of the foreign race fell down, causing a loud explosion. The ground trembled because of it. The foreign race died, and before everyone could carefully observe, the barbarian dragon went up after the foreign race died. It forcefully broke open the foreign race's body and took out a black crystal.

This black crystal was as big as a human head, surrounded by a black light. It looked like the energy crystal of the alien, just like the human Yuan Dan, exuding a pure aura. The barbaric dragon passed the black crystal to Zi Chen. Zi Chen tried to absorb it and found that he could.

In the human world, this was a Human Yuan Dan, and its value was immeasurable. Moreover, in the human world, there was a saying that by absorbing a Human Yuan Dan, one could break through to the Human Yuan Dan.

Zi Chen kept his Yuan Dan and looked at the dead foreign race member. Other than being taller than humans, having different energy levels, and having horns on their heads, there was nothing else special about them. However, the black Qi surrounding the foreign race member was like a naturally formed armor. If one did not destroy it, it would be very difficult to kill it.

With a preliminary understanding of the alien race, the group continued forward. Along the way, they would occasionally meet one or two alien races. Once they found an alien, they would rush up and kill them, collecting the black crystal.

However, Zi Chen was not satisfied with the speed of killing the alien race, because almost everyone present was an outstanding Xiantian expert, and their strength was at the late stage of the Inner Core realm. With the group working together and using their Xiantian skills, they could even kill a Human Yuan Dan expert easily. However, killing an alien race would take a long time.

After killing two alien races, the group didn't find any other alien races, nor did they see any other challengers. They could only feel the energy waves from time to time.

The group began to speed up, heading deeper. This time, they were about a thousand miles away. During the journey, Zi Chen found many corpses of challengers, and there was no lack of Xiantian experts.

In the first nine floors, Xiantian realm cultivators rarely died. But here, when facing the foreign races, even Xiantian realm cultivators were beginning to suffer casualties. Along the way, they also saw the corpses of foreign races. It was obvious that there were quite a few Xiantian realm cultivators who had the strength to kill the foreign races.

After a thousand kilometers, Zi Chen arrived at the center of the Dark World. There were even more Outsiders here, dozens of them, and they were fighting fiercely with many humans.

However, in this battle, the humans took the initiative to attack. During the battle, they continued to charge forward.

Up ahead, there was a stone platform. The stone platform was over a thousand square meters in size and emitted a black light. There were many runes carved on the stone platform. These runes were extremely complex and emitted a black light. When one looked at them, they would be dazzled.

The fierce battle between the foreign races and the human trial challengers took place outside the stone platform. And in the center of the stone platform, there was a towering stone pagoda. This stone pagoda was pure black and had a total of nine levels. It was a thousand meters tall, and the stone platform had dazzling patterns that extended all the way to the top of the stone pagoda.

Because of these patterns, the stone platform was connected to the stone pagoda. At this moment, what everyone was attacking wasn't the stone pagoda, but something floating at the top of the stone pagoda.

This was a black stone that looked like the size of a fist from afar. But in truth, it was as big as a millstone. The surface of the stone emitted a pure black light. As this black light left the stone, it turned into a black gas that spread into the distance, fusing into the black gas.

Above the Dark World, there was so much oppressive black gas. It was clearly emitted by this black stone. And this black stone looked like a piece of obsidian.

The black stone floated in the air. There were layers upon layers of spells on its surface, and it shined with a black light. It looked extremely extraordinary.

The reason the humans were constantly attacking was because of this black stone. As for the foreign races, because of this black stone, they were desperately defending. The battle between the two sides became increasingly fierce, and the human trial challengers suffered massive casualties.

This black stone that emitted a black light was the only thing in this world. Even if no one understood its function, they still didn't want to let it go.

"This is definitely something good. Let's go and take it."

Seeing that extremely extraordinary black stone, Tyrant immediately spoke without hesitation. This was the only thing in this world, and its importance didn't need to be deliberately explained.

"Let's go." Zi Chen's eyes flashed. He held the Dragon Soul Spear in his hand and rushed forward.

Tyrant and the others also rushed forward.

One of the foreign races discovered this group of uninvited guests. Black light surged around him. After repelling a group of human trial challengers, he rushed toward Zi Chen.

Black light flashed, and a pitch-black sharp blade appeared in the sky. It surged with an extremely terrifying aura and slashed toward Zi Chen who was in the lead.

A cold light flashed in Zi Chen's eyes. He swept his spear, and a dragon roar sounded. Bright silver light surged from the dragon spear and rushed out. Then, it turned into a silver dragon and collided with the black blade in the air.

"Boom!"

The two collided, and violent energy surged. The silver dragon shattered, and the black blade dissipated in the air. The destructive aura produced by the collision of the two energies began to distort the space.

Zi Chen turned into a bolt of lightning and rushed toward the foreign race in front of him. Zi Chen soared into the sky. Golden light flashed around his body. It was as dazzling as the sun. He struck a powerful Innate attack.

The foreign race clenched his fist. His fist, which was surrounded by black light, tore open the space and attacked Zi Chen fiercely.

"Bang!"

Both sides collided again, and an earth-shattering sound was heard. Zi Chen flew back dozens of meters in the air. The foreign race also took a few steps back because of this attack. His body became unstable.

The foreign race's red eyes were filled with surprise. Obviously, this was the first time he was beaten back by a human in a direct confrontation.

Zi Chen flew back. As soon as he stabilized his body, he began to form seals. Golden light danced between his fingers like golden fairies. As the seals were formed, a golden sun appeared in the sky.

This was a golden sun. However, it was not the pure power of the golden sun. It was the Extreme Yang Lightning. Around the golden sun, there were golden lightning snakes dancing wildly.

"Swoosh!"

As soon as the golden sun appeared, it turned into a golden light and rushed forward. With the speed of teleportation, it landed on the foreign race's body.

"Boom!"

The golden sun exploded on the foreign race's body. The golden lightning energy instantly engulfed the foreign race's body. It clashed with the black light on the foreign race's body and caused another explosion.

In this explosion, there was also a huge force. The foreign race's body kept retreating. The black light on his body was also destroyed by the lightning. The foreign race could not help but cry out in pain.

Just as Zi Chen was fighting one-on-one with the foreign race, Tyrant and the others had already rushed forward to the black stone at the top of the tower.

At the same time, the leaders of the other forces who had just killed the foreign race were also rushing toward the black stone.

"Scram!"

Before Tyrant could say anything, a shout came from the opposite side. It was Golden Flame and the others. Then, they launched an attack on Tyrant's group.

Tyrant's nose was almost crooked from anger. He was furious and shouted, "How dare you say scram before Lord Zeng says scram? You're courting death!"

As soon as he finished speaking, the golden light around Tyrant surged. He shouted again, "Bang!"

This was the first mantra of the Six-Syllable Mantra. Tyrant rarely used it. As soon as this mantra was used, it formed a strange destructive force that rushed toward the people in front of him.

Wherever the destructive force passed, the people's previous attacks were all destroyed. At the same time, the destructive force rushed forward.

Such a destructive force made the people's faces change drastically. They tried to resist the force. But in the next moment, a tremor came from the sky. It was a demon-subduing pestle that was as big as a mountain falling from the sky, smashing toward the people.

"Bang!" "Bang!"

In an instant, at least three Xiantian Realm warriors were hit by the demon-subduing pestle and fell to the ground.

"Damn it!" Golden Flame and the others looked gloomy as they looked at Tyrant.

"Gold Power!" In the next moment, Golden Flame shouted. His body emitted an endless amount of golden light.

The golden light was unusually dazzling. It was not much weaker than the one around Zi Chen. It formed a terrifying aura.

Boundless Gold Power surged and landed on the demon-subduing pestle. With a loud bang, the demon-subduing pestle was sent flying.

At the same time, all kinds of light surged and various kinds of energy exploded in the air. The sound of tremors was endless.

Longhu and the others also launched powerful attacks. At this moment, all the forces fell out with Zi Chen's group because they did not know the effects of the black stone.

Just as Zi Chen had predicted, when there was a conflict of interest, all the forces would unite and attack Zi Chen's group first.

"It's ours. Kill whoever dares to snatch it!" Golden Flame and the others shouted coldly.

Below, the foreign races died one after another. More Xiantian Realm warriors rushed up and a chaotic battle broke out.

In the face of so many Xiantian Realm warriors, Tyrant and the others were suppressed even though they were strong.

"Hurry up, we can't hold on for much longer!" Tyrant shouted at Zi Chen.

Opposite Zi Chen, the strange being was already riddled with wounds, his life hanging by a thread. His crimson eyes were filled with unwillingness as he shouted at Zi Chen, "Why? Why? Didn't we come to an agreement?"

Facing the foreign race warrior's question, Zi Chen shouted, "Idiot, who made an agreement with you? The foreign race must die."

Then, Zi Chen turned into a golden lightning again and rushed at the foreign race warrior. The foreign race warrior also turned into a black light and rushed at Zi Chen.

"Boom!"

The golden light and the black light collided, causing a huge explosion. After the explosion, the foreign race warrior's question echoed in the sky.

The battle above had reached its climax. Although no Xiantian Realm warriors had died, it was only a matter of time before they died.

During this time, the five of them had passed through Tyrant's blockade and reached the black stone above the stone tower.

However, before they could get close to the black stone, a silver light flashed in front of them.

When the silver light disappeared, they saw that there was another person beside the black stone.
