Heaven-defying Upgrade System

Although it may be dangerous to unleash the power of the sword, however, Lao Dao didn't hesitate to take the risk. He wanted to maximize the power of the sword technique. The color of the sky had completely changed, and only the dazzling light could be seen. It was so piercing that it hurt people's eyes. Some of the lower level students did not dare to look directly at it. Many people were trembling in fear. If they did not control this attack well... They could not escape even if they wanted to!    

    

The pressure instantly increased, and Liu Fei continued to defend. He stared at Lao Dao, who was standing opposite of him. Suddenly, a white light flashed in Liu Fei's eyes. Immediately after that, a tiny Pill Cauldron appeared on his forehead. Although it was only the size of a fist, it instantly emitted a scorching Qi. A colorful flame rushed towards Lao Dao. A part of the Golden Sun Sword Technique was instantly broken with a loud bang.    

    

"What is that!?" Looking at the magnificent flame, everyone was stunned. Liu Fei had actually spat out a flame, and this flame was actually so powerful.    

    

It seemed like it wanted to devour everything, even the Golden Sun Sword was melted by it.    

    

"This is impossible, how is this possible!? My Golden Sun Sword Technique is a sword technique comparable to a transcendent martial art!" Lao Dao roared in disbelief. He was now somewhat flustered. At this moment, it was not possible to retreat, nor was it possible to not retreat. Advancing would definitely be too dangerous. The flames unleashed by Liu Fei were charging at him one after another. He couldn't get close to it, and the flames could actually melt his sword technique. He might even be burned.    

    

Therefore, at this point, Lao Dao still cautiously retreated. This change shocked everyone. Their bodies trembled slightly as they stared at the flame, unable to speak.    

    

"He can even destroy a martial art that is comparable to a Mortal Realm martial art..." Those students muttered to themselves. If that was really the case, the flame that Liu Fei released could at least be considered a transcendent martial art! It could completely suppress Lao Dao's Golden Sun Sword Technique.    

    

"This is too inconceivable. That person actually began to gain the upper hand!" A student said in surprise. Only then did everyone recover from their shock, not bad. Lao Dao's retreat just now had given Liu Fei the perfect opportunity to attack. After Liu Fei spurted out the flames, he rushed forward as well.    

    

This battle could be said to be earth-shattering. The surrounding students could feel their hearts beating non-stop. It was as if they had already integrated into this battle, and they were still comparing the two in their hearts. If he really fought Liu Fei or Lao Dao, how much chance of survival would he have?    

    

"Bang!" A loud sound was heard. Lao Dao roared crazily, "I will not admit defeat!" At this moment, a flame that blotted out the sky and covered the earth had already struck above his head, and there were also streams of white sword Qi that pushed him to the extreme. As for Lao Dao's Golden Sun Sword Technique, because there was a flaw in it, it could no longer display its power. He could only rely on its remaining power to fight Liu Fei to the death.    

    

At this moment, Liu Fei suddenly felt a pain in his eyes. That was caused by the instability of the Heaven-defying Strength. The purple qi in his body was trying its best to balance the energy brought by the Green Source Polar Crystal and the Dark Soul Crystal. It could be said that Liu Fei was overloading the circulation of the Genuine Qi. If this continued... The consequences would be dire.    

    

However, Liu Fei had already withdrawn the Dragon Mark Cauldron. He used the remaining Glistening-Sky Primordial Fire to surround Lao Dao, and at the same time, the Taiji Cyan Rainbow Sword rushed towards him.    

    

Lao Dao was destined to lose. Liu Fei clenched his fists tightly. This battle was very tough, and Liu Fei didn't even know about it. If he met Lao Dao again, could he use the Glistening-Sky Primordial Fire to threaten him? This was the first time he had encountered a bad situation.    

    

"Stop!"    

    

At this moment, the high and mighty elder suddenly let out an angry shout. In the Heavenly Spirit Institute, these elders were incomparably dignified and their cultivation base was extremely terrifying. Since an elder had already spoken, no matter who it was, they had to listen to him.    

    

However, it was impossible for Liu Fei to stop now, because the Glistening-Sky Primordial Fire had already lost its control. Also, he couldn't withdraw his strength anymore. A portion of the Glistening-Sky Primordial Fire had already spread out uncontrollably, and the first thing that happened was that it was rushing towards Liu Fei.    

    

Cai Liuying clenched the magic treasure in her hand tightly, and stared at Liu Fei and Lao Dao. Now, she wanted to go and save them. Although Huo Feng and the others could see the changes in the situation, they didn't know where the problem was. Especially since Liu Fei was so calm, as if he was in control of the situation.    

    

"Stop it!" A scholarly master shouted.    

    

However, he did not dare to go up now. As a civil servant of the academy, his cultivation was not that high, and his martial arts were not very powerful either. If he went up now, he would only be courting death.    

    

Lao Dao was so shocked that his entire body was covered in cold sweat. Now, the Glistening-Sky Primordial Fire began to spread uncontrollably. His legs wanted to move, but they seemed to have gone limp. He could not muster up any strength to face Liu Fei's Glistening-Sky Primordial Fire. Lao Dao finally felt the taste of fear. Among them, he could see that the Glistening-Sky Primordial Fire that Liu Fei released... It seemed to be a kind of forbidden fire in the White Wood Clan, and it seemed to have something to do with the war that the White Wood Clan was attacked by the Centaur Clan.    

    

"Leader!" The people of the Silver Group stood up and shouted. They really wanted to rush forward and help. However, Huo Feng and the others were staring at them coldly. As long as they moved... The people of Gold Group would definitely make a move. At this moment, Huo Feng couldn't bear it anymore. He shouted at Liu Fei, "Lao Si, come down quickly. That place is too dangerous!"    

    

Huo Feng could see the power unleashed by the Glistening-Sky Primordial Fire. Even Liu Fei couldn't stop it.    

    

Liu Fei widened his eyes. He also wanted to stabilize the Glistening-Sky Primordial Fire. After all, killing Lao Dao here wouldn't do him any good. However, the Glistening-Sky Primordial Fire was no longer under his control. Liu Fei wanted to control it. It's already an impossible thing. Everyone couldn't help but widen their eyes. They didn't know how to describe their current feelings.    

    

Liu Fei's Glistening-Sky Primordial Fire had already destroyed the stage. One should know that this stage was specially designed to withstand an incomparably powerful force, but it was destroyed by Liu Fei.    

    

"Master!" Xiao Ruyu clenched her fists tightly. In her heart, she could only pray that Liu Fei was fine. Right now, she was unable to help, nor could she help.    

    

Suddenly, a green stream of light streaked across. A skinny figure appeared in the Glistening-Sky Primordial Fire. The Glistening-Sky Primordial Fire immediately burned towards this person, but when this person attacked... Suddenly, a white light lit up. It was actually suppressing the Glistening-Sky Primordial Fire.    

    

Liu Fei was slightly stunned. Looking at this old man in front of him, his cultivation base had already reached an unimaginable level. Liu Fei believed that if this old man's cultivation base was a little stronger, the Glistening-Sky Primordial Fire would probably not be able to hurt him.    

    

"Elder Deadwood!"
