On the human army's side, a dozen or so heavy armored vehicles formed a defensive circle. The blazing ultraviolet lights on the vehicles made it difficult for the ghosts to break through.
There were hundreds of poisons in the world, and there was always an antidote within five steps. Animals and plants that lived with poisons all year round must have a way to resist the poison. This was the way of evolution and Yin and Yang.
By the same logic, the place where the earth's core and the underworld intersected was also rich in ores containing special elements. Weapons made from these ores were also the nemesis of ghosts, such as silver, mercury, and other metals.
A dark-skinned, two-meter-tall, burly man was holding a six-barreled machine gun. Silver bullets were fired at an angle, and rows of ghosts fell one after another. The places where the bullets hit were burned.
He was yelling at the military helicopters circling above his head while shooting wildly at the ghosts.
"Scar, if you don't leave now, we'll have some fun together!"
A cold voice came from the helicopter. "Shut up, Sir Sound Saint is here. Protect the ultraviolet lights!"
Only then did the burly man notice Qian Kongjin, who was like a firefly in the sky, and the giant hand that was tightly surrounding her. He was dumbfounded. "Senior Sound Saint, can you do it?"
Thump, thump, thump … Right at this moment, a series of orderly footsteps came from the entrance of the valley. A troop of skeleton knights wearing black armor and holding huge spears appeared on the battlefield. Their green eyes scanned the valley, then they raised the spears in their hands and charged toward the human army.
Although this troop of skeleton knights was small in number, their aura was like that of an army with thousands of men and horses. Their steps were orderly, and they did not distinguish between friend and foe. They charged toward the human army in the blink of an eye.
The leader of the human army, the young man with the long spear, had a serious expression on his face. All the muscles in his body kept bulging and gathering power. The liquid flame energy stored in his lower abdomen was transferred to the long spear in his hand. Gradually, a purple-red fire dragon rose from the long spear.
As this fire dragon formed completely of pure flame energy appeared, all the living beings in the valley felt a scorching heat. The fire dragon roared at the sky and charged toward the skeleton soldiers. All the ghosts in its path were corroded into smoke. The troop of skeleton knights with an imposing aura could not hold on for long. They were instantly scattered by the fire dragon.
The fire dragon only dimmed slightly. It circled in the air for a while before retreating back into the long spear.
"Prairie Fire Spear Technique!"
The remaining human warriors were filled with energy again, and Big Black Khan roared in excitement.
A spear art with such power was naturally not an ordinary one. It was the Imperial Qian Family's Heaven Class Art, Prairie Fire Spear Art.
The Prairie Fire Spear Technique was a body technique that focused on the high degree of compatibility between the user and the weapon. It was said that when this body technique was cultivated to the extreme, all the bones in the user's body would be replaced. The spear in the user's hand had to be forged from the user's own spine. Only then could the user reach the realm of 'One with the Spear'.
Naturally, the one who used this kind of body technique was not an ordinary person. It was the Thirteenth Prince of the Qian Family, Qian Yuanhong. Now, he was already an advanced physical master. With the help of the Heavenly Level Body Technique, his specific combat strength was far beyond ordinary advanced physical masters.
The competition between species became more and more intense, and the living environment of human beings continued to deteriorate. However, like a spring, the greater the pressure, the stronger the rebound force. Over the years, shocking geniuses continued to appear one after another.
The Human Race, the Oceanic Race, and the Titan Race had formed an alliance. There was a ranking list among the three races called the Combat Sky Ranking. The Thirteenth Prince, Qian Yuanhong, was ranked tenth on the Combat Sky Ranking.
Saint Master Yun Shan had once said that anyone in the top ten of the Combat Sky Ranking had the strength to break through to the Saint Realm.
Qian Yuanhong held the spear upside down and felt the blood connection from the spear. In fact, there was a small opening on his palm that could be opened and closed at any time. Blood would flow into the spear and circulate around it before flowing back. Through this, he could reach the realm of 'One with the Spear'.
Among the five elements, fire was different from the other elements. It had the intention of destruction, so it could also affect people's temperament. Over the years, Qian Yuanhong had experienced many wars and massacres. Coupled with the influence of the martial arts he cultivated, his temperament had become more and more violent. Once he entered into an intense battle state, he would explode like a barrel of gunpowder.
At this moment, he could no longer control the rolling fire energy in his body. His eyes and hair had turned red, and his whole body was burning with flames. He stopped helping the army to defend and turned to charge into the valley.
Halfway there, he was stopped by two tyrannical ghosts. One of them was a Yin Soul without a specific form, and the other was a tall Zombie.
The Yin Soul used its method first. Its atomized body slightly condensed, and then it spat out a putrid black smoke. This black smoke had an extremely strong corrosive power. When it came in contact with the flames, it sizzled nonstop. It seemed to be able to corrode even the flames.
The Zombie's body continued to expand, and it became several times bigger. A pair of rhinoceros-like horns grew out of its head, and a black trident appeared in its hand. Its body was covered with a thick layer of carapace, and it looked very strange.
The two sides instantly clashed. The Yin Soul focused on speed. Its body flashed as it surrounded Qian Yuanhong and spat out black smoke. This black smoke was a type of powerful dark energy that could corrode any material energy. When Qian Yuanhong's spear came in contact with it, he immediately felt that the connection between him and the spear had decreased a lot.
The Zombie faced Qian Yuanhong head-on. Its body was extremely hard, and the spear only left a white mark on its body.
Qian Yuanhong didn't lose his mind. It was just that when the cultivation method was activated to a certain extent, it had to be vented. He relied on his agile body to dodge the Zombie King's attack while trying to lock on to the green-faced evil ghost. However, this ghost was too slippery. It was invisible and formless, and at the same time, it was much faster than him.
If it weren't for the high-strength protective equipment he was wearing, he would have been defeated in an instant.
At this time, the human side had run out of ammunition. The black man threw away the six-barreled machine gun in his arms and pulled out a short knife to fight the zombies that pounced on him.
The last armed helicopter in the sky ran out of power, and it was quickly taken over by the Yin Soul.
A man with a long scar between his eyebrows jumped down from the helicopter. He landed beside an armored vehicle, and his body was covered with lightning. Every time he waved his hand, a bolt of lightning would appear out of thin air, and the ghosts that pounced on him would be turned into smoke.
"Scar, where is the Thirteenth Prince?"
The black man hurriedly asked him. As the team shrank, they were surrounded by zombies, and the sky was full of Yin Souls. They couldn't see the situation in the distance.
The scarred man replied solemnly, "He is fighting with two high-level evil ghosts!"
"What about the Sound Saint?"
"The Sound Saint is facing two ghosts that are not weaker than human saints."
"Ah, what should we do?"
The scarred man spat hard, "What else can we do? Let's fight."
Qian Yuanhong was in a tough battle. If he faced one high-level evil ghost alone, he wouldn't be afraid at all. However, it was a bit troublesome to be surrounded by two high-level evil ghosts. One of them was close to him, and the other was far away. One had a strange figure that could spit out disgusting black smoke from a distance, and the other had a hard body and incomparable strength that could resist his Prairie Fire Spear Technique.
On the Sky Battlefield, Qian Kongjin was facing the endless Yin Souls. From time to time, she would issue a sharp and long cry. Layers of sound waves would spread out, and countless Yin Souls would be shattered by the vibration. But then, under the guidance of an inexplicable power, the Yin Souls would condense again.
A layer of dark clouds floated in the sky, and countless ferocious evil ghosts were looming in the rolling fog. They were led by a beautiful woman with a delicate face to fly toward the valley.
At the same time, the sound of neat footsteps came from the entrance of the valley again. Dense skeleton cavalry with long halberds poured into the valley. The leader was a knight wearing a horned helmet and dark golden armor. The golden light emitted from his eye sockets seemed to be solid.
Qian Kongjin was the first to notice it. Her face couldn't help but change. There were two more Saint-level evil ghosts!
An evil and cold aura pervaded the valley. The remaining human soldiers first felt nauseous and vomited. Then their bodies itched, and they couldn't help but want to scratch. However, once their blood was exposed to the air, it would start to rot immediately.
When they saw two more Saint-level evil ghosts, the soldiers had already fallen into despair. The black man looked up at the evil ghosts that covered the whole sky and said in a trembling voice, "Scar, do you think the Sound Saint can deal with four Saint-level evil ghosts?"
The scarred man lost his composure. He shook his head with a pale face and said, "I don't know."
At this time, Qian Kongjin in the sky suddenly put away her giant sword and took out a black jade flute. She sat cross-legged in the air. When she put the flute to her lips and was about to blow it, she heard a man's reproachful voice, "You don't want to live anymore. You know you don't have much time left, but you still want to use the origin power."
