Heaven-defying Upgrade System

Not only Liu Fei, but Nangong Yingjie and the others also perked up their ears. The elder who lived in the underground city seemed to have some incredible secret that he wanted to reveal.    

"The meaning is very obvious." The elder continued, "I'm sure you already know about Mu Qianqiu, and those experts who changed from a cultivator to a Cultivator of the Devil Clan. Not only did they betray Lord Corpse Demon, but they also went against Lord Corpse Demon's will. They actually coveted wealth and became the dogs of the Da Ming Dynasty. Lord Corpse Demon had long been furious about what they had done! And you have destroyed their camp. You have done a very good job! "    

The elder was not saying the opposite. He was indeed praising Liu Fei and the others.    

Liu Fei and the others gradually understood what he meant.    

The Devil Clan army in the underground city seemed to be on two different camps with Mu Qianqiu's Devil Clan army. From their words, Liu Fei and the others could feel that these people were fighting in their nests!    

"Kid, your cultivation base is very strange. You are clearly only at the Third Sky of Spiritual Core Stage. But strength makes me a little unable to see through it..." After saying that, the elder twisted his goatee. After that, he narrowed his eyes and looked at Liu Fei. The expression in his eyes was unfathomable.    

Liu Fei thought to himself. It seemed like this man was a very cautious person. He didn't look down on him just because he was at the Third Sky of Spiritual Core Stage. It seemed like he was a tough guy to deal with.    

"Elder Beifeng, what's there to talk about with this guy? Just kill them all!" Elder Huo Kui glared at Liu Fei and said while gnashing his teeth in anger.    

"Ai..." Elder Bei Feng waved his hand at Huo Kui, then said to Liu Fei, "Kid, I think you should understand what this old man is trying to say! The strength of you people isn't weak, and I can feel it. All of you are rare and precious talents. Why don't you follow us and pledge your loyalty to Master Corpse Tyrant? At that time, whether it's the Da Ming Dynasty or the Great Wei Dynasty... it will be our world. What do you think? "    

"Hahaha..."    

As soon as Elder Bei Feng finished his words, Liu Fei burst into laughter. Even Nangong Yingjie and the others couldn't help but let out a cold laugh.    

"What a joke!"    

Yama even let out a cold shout. He wanted Black Flame Devil, who was once high and mighty, to pledge his loyalty to a little devil whom he had never heard of before. If it wasn't a joke, what else could it be?    

After Liu Fei laughed out loud, he said, "Good! Good! Let me ask you, since you have the ambition to rule the world, but why is he hiding in this dark and cold place and not daring to go out? Is he afraid that his strength is not enough to dominate the world?"    

"Kid, you... Elder Beifeng! What's there to talk about with these ignorant people!?" The rage on Huo Kui's face grew deeper and deeper as he stared fixedly at Liu Fei and the others, and he wished for nothing more than to eat them alive.    

Elder Bei Feng closed his eyes. A bright light was hidden in his eyes. He shook his head and said slowly, "We don't work together when we have different paths. Since you refuse to accept a toast, I'll let you know what true power is!"    

Hearing his words, Liu Fei sneered and said, "Perhaps your strength is very strong, and I have no choice but to be wary of you. But if you want to swallow up the whole world in one go... Hehe, there is still a long way to go! You're just a bunch of delusional frogs at the bottom of a well!"    

" You! " Elder Huo Kui was already fuming with anger. To actually compare him to a frog...    

"Go to hell!" Elder Bei Feng suddenly opened his eyes. One had to admit that he was a cunning old fox. During the time he was conversing with Liu Fei, he had already secretly prepared everything and attacked first!    

Elder Bei Feng threw out a black magic treasure. The magic treasure was like a funnel as it flew into the sky. Elder Bei Feng immediately let go of the hand seal he was forming.    

A funnel shaped magic treasure suddenly split open in the air, and following the circulation of Elder Bei Feng's magic skill, a crack appeared. The funnel began to spin crazily. In an instant, a black viscous liquid shot out from the magic treasure. At the same time, a strange, stinky smell spread out in the air. It was extremely unpleasant. Nobody knew what kind of disgusting thing it was.    

After the black viscous liquid was spat out, it quickly condensed into a huge snake. Its entire body seemed to have been fished out of a swamp, wet and full of terrifying protrusions. Like short tentacles, the magic treasure directly merged with its body. It turned into a triangular head, and two soul-stirring red lights flashed out. Everyone was illuminated by the red light and immediately felt a trance.    

After that, the giant snake-like monster was wrapped in black fog. It roared and charged at Liu Fei!    

Liu Fei had never thought that this monster would be so agile, even though he had a 50% increase in speed. He was suddenly pounced on by this monster. He didn't even have the chance to defend himself before he was tightly bound by the monster.    

Liu Fei instantly felt that the air surrounding him was extremely dense. An extremely powerful pressure was pushing him towards the center. Liu Fei tried to break free, but he found that this giant snake-like monster was wrapping around him. The more he struggled, the tighter it wrapped around him!    

"Ka... Ka..."    

The bones on Liu Fei's body made a clear sound at this moment, as if they were going to be crushed and broken.    

"Kid, slowly taste the taste of suffocation... Kaka..." Elder Bei Feng let out a sinister and strange laugh. His calm and magnanimous appearance had completely disappeared. His ferocious side was gradually revealed. Compared to before, he was like a completely different person.    

"Let's go!" Nangong Yingjie waved his hand and called the Sky Whistling Team members behind him, preparing to rescue Liu Fei.    

But at this moment, Elder Huo Kui suddenly appeared in front of them. He raised both of his hands, and gravel spurted out from the top of his head. The gravel rotated crazily in the air and instantly formed a terrifying hurricane. After that, Elder Huo Kui swung both of his hands and threw the whistling sand and stones in front of Nangong Yingjie and the others.    

"Set up the formation!"    

With a loud shout, the members of Sky Whistling Team immediately set up the Nine Palace Sword Formation. At the same time, Yama also took out his Dragon Slaying Saber. With a flash of the blade light, the blade energy instantly expanded, forming an oval shield around Yama's body. The cold blade energy protected him inside. When the crazily spinning hurricane rushed to his side, it violently rubbed against the blade energy, and balls of scorching flame gushed out from the hurricane.    

After the Saber Qi rubbed against the sand, although the unusually hard sand could not break through the Saber Qi's defense, it instantly burned when it collided with the Saber Qi.    

"Not good!"    

Yama's heart skipped a beat. He instantly sensed that something strange was happening! This way, the power of the burning gravel in the hurricane seemed to have become even stronger!
