Heaven-defying Upgrade System

When Gray-robed Elder was young, his name had shaken the entire Tianqi City. If it wasn't for the fact that he had encountered a great disaster that caused him to be unable to advance to the Mortal Core Stage, he would definitely be an existence on par with his father.    

It would be a piece of cake for such a figure to deal with a puny Liu Fei.    

Liu Fei, on the other hand, was pushed three steps back by this wave of Qi. He couldn't help but look at Liu Fei with a cold gaze, "Ninth Layer of Body Tempering Tian is indeed powerful!"    

"Since you know about it, kneel down and accept your death!"    

Gray-robed Elder shouted and took a few more steps forward. Every step he took caused a powerful Qi wave to explode. After that, his withered right hand reached out like a devil's claw from hell. With a speed that was neither fast nor fast, but unavoidable. He wanted to grab Liu Fei's head!    

"Die? In your dreams, watch my Profound Heavenly Change!"    

Liu Fei shouted out loudly. Without holding back, he unleashed the Profound Heavenly Change.    

In an instant, a bright light emerged from underneath his feet. Like a tidal wave, it surged all over his body.    

At this moment, Liu Fei's Qi rushed out of the mouth of the volcano like hot magma, reaching an even higher heaven and earth!    

"This is..."    

Liu Fei's Qi suddenly became stronger, startling Gray-robed Elder. But before he could retreat, Liu Fei had already taken a step forward and slapped him.    

Slap!    

In the next second, a crisp sound was heard. Everyone saw in horror that... Gray-robed Elder, who had just displayed his invincible aura, was slapped by Liu Fei. He was slapped on the old man's face without any resistance. He was sent flying!    

"What..." Gray-robed Elder was worthy of being called a Ninth Layer of Body Tempering expert. As he was sent flying, he twisted his body in the air and landed on the ground. He staggered a few steps before he could stabilize his body. However, he didn't fall down.    

Gray-robed Elder was shocked. Liu Fei's speed was just too fast, it was exactly the same as a Mortal Core Stage warrior.    

However, he also had doubts in his heart, because if it was really a Mortal Core Stage warrior, he would have died a long time ago when ___ slapped him.    

He took a deep breath and touched his wrinkled face, which was still burning with pain. He gritted his teeth and said fiercely:    

"Kid, it seems like you have some tricks up your sleeve. If that's the case, then I'll have to take it seriously. Once I take it seriously..."    

Pah!    

Everyone saw that Liu Fei had turned into a gust of wind, and they couldn't even see his shadow clearly. He rushed in front of Gray-robed Elder, and with a crisp sound, Gray-robed Elder was sent flying once again.    

* Hong! *    

Gray-robed Elder didn't stand up this time. He fell to the ground, but he didn't lose his fighting ability. Instead, he stretched out his hands and tried to stand up, but he kept shaking his head. It could be seen that he had been beaten into a daze.    

Actually, it wasn't just him who was stunned. The surrounding people were all stunned.    

What kind of joke was this? Liu Fei actually treated Gray-robed Elder like a child and slapped him. This Gray-robed Elder was a Ninth Layer of Body Tempering expert!    

Wang Shaoyi's mouth was wide open. In his imagination, Liu Fei was the one who got beaten up. How could the reality be the complete opposite of what he imagined?    

However, he quickly regained his senses and shouted, "Are you still holding back?! Hurry up and kill Liu Fei!"    

Liu Fei waved his hand and walked towards Gray-robed Elder. He muttered to himself, "I'm really not familiar with the strength of a Mortal Core Stage. I didn't even kill him with two slaps. This is too embarrassing. I thought I could kill him with one slap. I hope the third slap can bring out the true strength of a Mortal Core Stage! "    

Gray-robed Elder finally stood up. He was also furious. He was actually slapped twice by a junior. This was unforgivable.    

"Brat, I will cripple your cultivation. I will cut off a hundred cuts on your body, then throw you into an ant's nest. I will make you suffer all kinds of hardships. I will make sure that you will not be able to survive..."    

"Beg your mother!"    

Liu Fei sneered. He raised his hand and slapped again.    

This time, Gray-robed Elder held his breath and focused his mind. He unleashed 100% of his strength, preparing to block the slap.    

However, when this slap flew over, he realized that he was wrong. This slap was too fast, and he couldn't see it clearly. It wasn't something he could block with his cultivation base!    

Bang!    

This time, it wasn't a crisp sound, but an explosive sound. Gray-robed Elder's head was directly smashed into pieces by Liu Fei's slap. The Blood Fog that filled the sky scattered, and a bloody smell filled the air!    

"This, this, this, this..."    

In an instant, all the people who were preparing to watch Liu Fei make a fool of himself were stunned.    

Liu Fei had actually killed Gray-robed Elder with three slaps?    

Wang Shaoyi was also stunned. This Liu Fei? Was he really a Zero Class Talent trash? If that was really the case, how could he have the strength to kill a Ninth Layer of Body Tempering warrior with three slaps?    

Wang Shaoyi couldn't help but fiercely pinch his thigh, wanting to see if he was dreaming.    

On Liu Fei's side, the system notification rang at the right time.    

"Ding! Congratulations to host for killing Gray-robed Elder who is a higher level than you. You have obtained the achievement" You are strong as you please, "you have received the reward..."
