The black sun glows and is full of magic.

Tietu's breath suddenly changed, and the black light flashed between his hands, and he disappeared without a trace, directly attacking Hu Yanyao and Jiang Kui, who were facing away from him. This is a black knife, good at assassination, and it is the Xuan-level artifact that Ao Zhan gave him-the Ethereal Knife.

'Bell!'

With the sound of a metal clash, the original hit was blocked by Hu Yanyao, who turned around, and Jiang Kui went to block Lei Dian.

"Haha, I knew you would be like this!" Hu Yanyao laughed, holding the golden spear of the gods, and was on guard.

"How do you know?" asked Tietu, frowning.

Hu Yanyao sneered, spread out his hand, and there was a broken jade piece in his palm.

"Soul Jade. Tietu instantly understood.

"I didn't shoot the last of my men to save him, but to let him be a 'lighthouse' to give me tips. Haha, as soon as his soul jade was shattered, you appeared, and it was obvious who killed him. Besides, I never trusted you. Hu Yanyao sneered.

"Then let's fight!" Tietu was not angry, gritted his teeth and killed him.

"Hmph, do you still want to use my Hu family's ethereal knife to sneak attack me?" Hu Yanyao sneered, and the spear of the god stabbed straight away, like a dragon out of a hole.

'Boom!'

The waves of air flew, and several black rays of light swept by the ethereal knife, cutting through the golden light.

"Huh?" Hu Yanyao lowered his head and found that he had an extremely thin wound on his chest, and blood flowed out after a few movements of his body. The wound was thin but deep, and suddenly a sharp pain emerged, which was the power of the ethereal knife.

He was already badly wounded and could not fight again!

"Old Jiang, go!" Hu Yanyao was extremely decisive and immediately greeted him.

Although he Hu Yanyao was a little careless, he was injured in one look, which has already explained some problems.

"Let's go?" Tie Tu shook his body, raised his hand, and a few black lights streaked across the sky.

Hu Yanyao raised his hand to resist, but he didn't feel pain on his body again, and he understood that he had been stabbed again. But he couldn't figure it out, why did Tietu's power suddenly skyrocket?

"How did he survive and how did he come out?" Hu Yanyao thought to himself.

At this time, Jiang Kui was also wounded, and his left shoulder was slashed open by Lei Dian's claw knife, and blood was sprinkled indiscriminately.

"Let's go!" Jiang Kui escaped with a knife, and fled with Hu Yanyao.

Tietu chased after him, and at the last moment, Ao Zhan, who was being carried, suddenly became difficult, and the blood in his hands was magnificent, and a fierce ferocity rushed straight to the soul.

A blood-colored broadsword suddenly appeared, and nine golden rings flew out of it, like a star impact!

Hu Yanyao and Jiang Kui didn't expect this one at all, and they were hit before they had time to defend. The two of them spilled blood in the air, and they were hit by nine golden rings and suffered many fractures and fell.

But soon, the two of them turned into two streamers, I don't know what secret technique was used, so fast that Ao Zhan and Tietu didn't even have the idea of chasing, they could only watch them disappear into the horizon.

"It's a retreat technique that burns life qi, which can increase speed for a short time, but it is a great burden on oneself, and it may be weak for a long time, and they dare to use it in the ruins, but they are also forced to be anxious. Tietu took the initiative to explain.

"It's as if everyone is going to be such a trick, forget it, don't bother to chase them. Ao Zhan pouted, quite helpless.

In his impression, people with a little bit of identity will have such a secret art of escape, among which Hu Xiong's blood escape speed is the fastest and the counterattack is the most terrifying.

"Hmm, Lei Yan has escaped!" said Tie Tuwu.

Ao Zhan saw Lei Dian turn into a thunder shadow, and fled towards the east at great speed, although the speed was not as fast as Hu Yanyao and Jiang Kui's escape skills, but it was also extremely fast.

"Chasing?" Tietu asked indifferently.

"Chase!" Ao Zhan nodded affirmatively.

Tietu took Ao Zhan, and the speed unfolded all of a sudden, and it was also very fast to run east. After some time, they saw Lei Dian's back again.

The black sun is overwhelming, and it is so huge at this moment, and the blood atmosphere is thick, making people seem to stand in the sea of corpses and blood, and they are confused for a while.

"What is he doing?" Ao Zhan pointed at Lei Dian, not knowing why.

Thunder slumped to the ground, his hands and feet kicking the ground like an animal struggling. He let out a strange roar that was so sharp that it went straight to the soul. Outsiders can't imagine his pain at the moment, but they see a change of color.

Tietu didn't speak, just frowned at Lei Dian's strange behavior. During this period, Lei Dian raised his head and roared several times, and even let out a wolf howl as if he were nothing, which made Ao Zhan and Tietu secretly surprised.

"What the hell is going on?" asked Ao Zhan with a frown.

Tietu just shook his head, he hadn't seen this before. A man struggled and roared like a wild beast.

When he looked at it again, Lei Dian's clothes had been torn off, revealing a pale blue mane, his nails on his hands and feet had grown wildly, his eyes were as blue as thunder, and the most peculiar thing was that his ears had become as narrow and sharp as wolf ears.

A thought suddenly sprung up in the depths of Tietu's heart!

"Could it be, is it that kind of change?" Tietu felt his throat dry and swallowed.

"What change? Explain it clearly!" Ao Zhan was puzzled when he heard this, and he couldn't help but be a little annoyed.

"Maybe it's not a corpse, it's a legend—the awakening of the demon soul!" Tietu took a deep breath, his eyes glinting.

"What do you mean?" Ao Zhan became more and more confused.

Tietu was still immersed in shock, and he was not surprised that Ao Zhan didn't even know these common senses, and explained in a daze, "The demon soul is determined by heaven, there is no one in ten thousand, and there are even fewer people who can awaken, legend has it that tens of thousands of years ago, all the saints competed for hegemony, almost all of them were demon souls, and the heavens and the earth were shaken!"

"Demon Soul ......," Ao Zhan frowned and muttered.

"There are three kinds of demon souls, one is a peerless and rare alien soul, the other is a relatively rare instrument soul, and the other is a relatively common beast soul!" Tietu continued.

Ao Zhan was stunned, and then pointed to the painful and struggling Lei Dian and said, "Could it be that he is in the process of awakening the beast soul?"

"I haven't seen the scene of the demon soul awakening, but I'm afraid it is!" Tie Tu's voice trembled slightly.

"The awakening of the demon soul is so painful, what changes can there be after awakening, will it increase its power dramatically?" Ao Zhan asked with interest.

"There will definitely be an increase, but it won't be an exaggeration to awaken, the demon soul will continue to grow, and it will become more and more terrifying in the later stage, but this is also my hearsay. Tietu said with envy.

"Hey, look at Lei Dian!" Ao Zhan shouted.

Lei Dian, who was originally curled up, suddenly raised his head and roared, and with a shock of his hands, a circle of thunder light qi waves scattered out in all directions, rolling up the blood and sand in the sky, stirring up a large stream of bloody qi.

Ao Zhan and Tietu had to hide their faces and avoid their heads. After waiting for the four times to return to tranquility, Lei Dian has disappeared, and there is not even a trace left, which is very weird.

"I can't follow. Ao Zhan was deeply unlucky, and then said, "This thunder ran to the east before, I think there must be something strange in the east, let's go, let's take a look." ”

Tietu didn't speak, and followed indifferently behind him. As a blood slave, Ao Zhan can make him uncomfortable at any time, and he can only obediently obey orders.

In the east, where the black sun rises, the darkness is infinite and unpredictable. With the help of several luminous stones, the two of them could barely maintain a radius of five or six meters.

Here, at last, there is another discovery.

Corpse, the corpse of the warrior of the Treasure Pavilion!

Ao Zhan and Tietu examined it carefully, and found that these corpses were very broken, all of them were claw wounds, very similar to Lei Dian dry.

"Hmm, why does it look a little familiar?" Ao Zhan suddenly raised his eyebrows and picked up a very exquisite jade hairpin from the blood bubble.

"It's Feng'er's jade hairpin. Tietu said firmly.

"Is that girl's?" Ao Zhan said in surprise, "If it was hers, then she must have been here, but she was taken away by Jiang Kui, but when we met Lei Dian, she was not in Jiang Kui's hands at all, could it be that she escaped here alone and killed so many Treasure Pavilion martial artists?"

"She can't kill her, and the corpse is not right!" Tietu shook his head flatly.

"Yes. Ao Zhan nodded.

With Tie Feng'er's cultivation in the Void Underworld, it was obviously impossible to kill these Treasure Pavilion elites. But how did she get here, where is she now, and what is hidden in the ruins?

With all kinds of questions, the two continued on their way. During this period, he used his keen sense of blood and qi to continue to explore, and the little centipede also appeared from time to time to remind a few words.

Encountering several ancient formations on the way, they were all discovered in advance and did not fall into them. This place is not so much a ruin as an unknown battlefield, full of hidden ancient formations, and the entire surface of the earth is full of blood.

"Is this an ancient battlefield?"

Ao Zhan suddenly thought of what Tie Tu said before, tens of thousands of years ago, the saints fought for hegemony, could this be one of the battlefields?
