Heaven-defying Upgrade System

"Yeah, it's said that iron crystals are special things. I don't know why this material is so rare and extremely precious. " Lu Feng nodded and said. Liu Fei nodded secretly. Luckily, he had seen such a thing in the system. Otherwise, he really wouldn't be able to tell the benefits of this treasure. * Crack * The iron chain instantly moved like a moving iron dragon. It quickly surrounded the Green Source Beast, and at the same time, it also separated many sharp blades from its side. It charged straight at the Green Source Beast.    

    

However, the Green Source Beast did not seem to have any intention of struggling. Everyone couldn't help but widen their eyes in shock and swallow their saliva. Staring at everything that was happening in front of them, they thought in their hearts, Could it be that this Green Source Beast wants to sit and wait for death?" If he didn't take any action, he would only end up being killed. At this moment, the Green Source Beast roared. His feet trembled slightly on the ground, as if there was a pattern to it. The person who saw it was very puzzled. Suddenly, the ground beneath his feet split open. Green vines drilled out of it and quickly covered his entire body.    

    

"What is this thing?" Everyone was shocked. Could this be the defensive technique of the Green Source Beast?    

    

"Kill!" Ma Fengfeng shouted loudly, and the Green Source Beast did not want to be outdone. The spikes on the vines suddenly rushed out like a storm. The powerful Qi instantly blocked the iron chain. Ma Fengfeng sneered and said, "Humph, such a small thing can also block my attack?" As he spoke, he stood in the air and pointed with one hand. The instant time iron chain started to spin crazily. It emitted an overbearing aura and instantly scattered the flying spikes. The crystalline blue light began to suppress the spikes as if a god had descended.    

    

The Green Source Beast was still calm and composed as if it had expected this. It silently formed hand seals, and the spikes gathered once again, turning into a special sharp blade. The horse flew towards the wind, and he bent his body slightly. The vines followed his body and began to grow crazily. The surrounding people were shocked and cried out in their hearts, Not good! This Green Source Beast is accumulating strength! It seemed like he was about to counterattack. Ma Fengfeng's eyes moved, and he dodged the attack of the spike. At the same time, a protective Genuine Qi erupted from his body, and it continuously blocked the attack of the spike. At the same time, he dodged the attack, or else he would be struck by the tiny spike. Who knew what the consequences would be?    

    

Suddenly, the Green Source Beast's eyes lit up like a blooming flower. With a furious roar, the vine began to become extremely thick. The Green Source Beast moved its arms and the spiritual energy that was stuck to it slowly dissipated. It was absorbed by the vine. At the same time, the vine grew at a much faster rate, and soared into the sky. It was majestic. Anyone could feel the spiritual energy emitting from it, it was simply too terrifying. It was as if it was going to shatter everything. Lu Feng's heart skipped a beat. She was not worried that she would lose the bet with Liu Fei. It was about whether Ma Fengfeng's life would be in danger. After all, he was also an expert in Lu Family Castle. If he died, it would definitely be a huge loss to Lu Family Castle.    

    

"Hmph! You think you can deal with me? Die!" The Green Source Beast roared furiously and rushed forward at lightning speed, striking out with a loud bang. It broke through the blockade of an iron chain, and the strange and mysterious vine instantly rushed in front of Ma Fengfeng. "Die!" The Green Source Beast roared, and something that looked like long fur instantly flew out from its body. A huge group of vines rushed towards the horse and surrounded it.    

    

"Why aren't you admitting defeat? Aren't you courting death?" Someone shouted in confusion. "This isn't a power he can resist at all!" "Could it be that Ma Fengfeng has some other strange move?" Someone said. The crowd started to discuss among themselves. As the battle got more intense, everyone's hearts were in their throats, and Lu Feng was also very worried. Only Liu Fei looked like he didn't care about anything. He just looked at it casually. He even frowned, as if he wasn't interested.    

    

Lu Feng couldn't help but ask, "Do you think Ma Fengfeng will die?" Liu Fei said lightly, "I don't think so." Lu Feng frowned slightly and said, "Can you be more serious..." She was very nervous now. Liu Fei saw the vigorous vines. They were like tentacles that almost completely surrounded the horse.    

    

Suddenly, Liu Fei seemed to have sensed something. He frowned slightly and said, "It should be over soon."    

    

"What..." Lu Feng looked at him in confusion.    

    

But at this moment, she suddenly heard the horse that was completely surrounded by vines. She said, "Inextinguishable Heavenly Lightning!" Rumble! A huge thunderous sound suddenly rang out. Within the vines... Suddenly, a ball of lightning attribute aura burst forth. Following that... A loud bang sounded as though it had exploded. First, a dazzling white light had nearly obscured everyone's vision. Then, the sound of the explosion rang out. In an instant, a powerful force broke through the attack of the vines. One! A human figure appeared in front of everyone's eyes and slowly walked out from the silver-white Lightning.    

    

Everyone was shocked as they looked at what was happening in front of them in disbelief. Liu Fei smiled faintly as if he had already predicted something. An old man who was watching said, "This Indestructible Heavenly Thunder is a super martial art, and it possesses extremely powerful power. It's very difficult to control, but once it's successfully cultivated, its power is beyond our imagination. Moreover, this kind of martial arts technique can be used as a footwork technique " The group of young cultivators at the side couldn't help but nod.    

    

Liu Fei looked at the Green Source Beast and the horse facing the wind and frowned slightly. He clicked his tongue. Lu Feng immediately noticed his situation and hurriedly asked, "What do you want to say?" Liu Fei originally did not want to say it, but he could not convince this girl. He felt that he could not hide anything from her, so he whispered in Lu Feng's ear, "This is just a performance in the warbeast arena. Although both of them have released a very powerful force. But the attack just now didn't have that much hostility, and I almost couldn't feel any killing intent. So, you understand... "    

    

Lu Feng was shocked. How could the result be like this? Liu Fei was afraid that she would not understand, so he pointed his mouth at the Green Source Beast. He said, "You see, that guy's movements can clearly be very fast. But why didn't he seize the opportunity to attack quickly, and his strength was amazing, when that horse approached against the wind, it was simply no match for him. He could directly approach the horse against the wind. Even if the opponent used the Indestructible Heavenly Lightning to escape. He could also chase after it. This way, he would definitely be able to suppress the other party. If this is really a fight to the death, then there's no need for me to waste so much time talking to Ma Fengfeng, right?"    

    

Lu Feng slowly recovered from her shock and said, "After hearing what you said, it seems to be true."
