Heaven-defying Upgrade System

2Lu Ming flew up to the sky and stood beside Lu Feng. He said to the people below, "Everyone, I am the son of the Lu Family Castle's City Lord, Lu Ming. What little sister Lu Feng said is right. His father had been bewitched by the demonic words. The Great Demonic Beast was just outside. They will arrive at the city very soon, but please don't worry. Since we can resist the Great Demonic Beast once, there will be a second time. Everyone must work together and unite into a city, only then will there be a chance! If we only want to escape, we will fall into the Sorcerer Group's trap."    

    

Although Lu Ming's prestige was not high, he was still Lu Chen's son. What he said carried some weight. Lu Ming and Lu Feng stood together and said that. This meant that this was most likely the case. Although everyone was terrified, many of the seniors had experienced that dark era. They immediately responded, "We will definitely defend the city with all our strength. We will definitely not allow the Great Demonic Beast to break into the city!" Everyone was united. When Liu Fei heard this voice, he couldn't help but raise his thumb towards Lu Feng. Good job in his heart!    

    

Lu Feng smiled, her face full of satisfaction. Liu Fei turned his head to look at the black shadow. The other party obviously did not expect things to develop to this extent. Originally, he was prepared to make a move immediately. But at this moment, he hesitated slightly. Those people from the Lu Family had already arrived at Liu Fei's side, waiting for his order. Lu Ming said, "All the cultivators in Lu Family Castle are now under Young Master Liu's command. Let's fight the Great Demonic Beast together and protect Lu Family Castle!" Lu Feng repeated her words. She had handed over the authority to Liu Fei. Everyone was stunned. They hastily handed over the life and death of the Lu Family Castle to an outsider. It was a little inappropriate, not to mention that Liu Fei was still very young.    

    

However, this was already a decision made by the higher-ups. Even if they wanted to oppose it, they had no choice but to do so. Because of the urgency of the situation, there was no chance for them to refute. They could only silently pray. Liu Fei was very shocked in his heart. He never thought that he would have to lead a Lu Family Castle with millions of people. However, Lu Feng and Lu Ming had already said to him, "Liu Fei, we all believe that you can do it!" The old strategist of Lu Ming said, "Young Master Liu, the City Lord is no longer the City Lord of the past. He is now a man with strength and brains. You are the only one in the entire Lu Family Castle who can take up such a big responsibility! " Liu Fei broke out in cold sweat. This responsibility was a little too big!    

    

In fact, Liu Fei had only come to see Wanyan Tine. He had never thought that the Sect Master of the Lu Family Castle would come. However, everyone had placed their hopes on him, which made it difficult for him to refuse. In order to make everyone feel at ease, Liu Fei said in a deep voice, "Everyone, don't worry. I, Liu Fei, swear here that I will kick the Great Demonic Beast out. Protect the Lu Family Castle. Please fight with me! " Immediately, cheers sounded from below, and everyone's hearts were ignited at this moment.    

    

However, Lu Hsing felt that he was at a disadvantage. However, the followers behind him had some strange thoughts. That was, Lu Chen would definitely defeat Liu Fei. At that time, Lu Ming and Lu Feng would come out. In the entire Lu Family Castle, only Lu Hsing was left as the heir. But even so, they didn't dare to oppose Liu Fei. On the contrary, there were more of them. The black shadow stayed in the air for a while and finally sneered, "Hehe, you few juniors can actually take care of such a situation. Indeed, I didn't expect it, but you guys are looking down on our methods too much!"    

    

Liu Fei stared at the black shadow and was ready to fight. The black shadow seemed to have adjusted Liu Fei's position, and said coldly, "I heard that you use the fire attribute well, so let's have a competition. Who has the better martial arts?" Without waiting for Liu Fei's reply, the black shadow shot out a black flame. Like a floating ghost, it rushed towards Liu Fei. In an instant, all the soldiers moved out, but Lu Feng stopped them and said, "Gather all the formation masters immediately. Even the Array Picture Masters must be called over. Let them reinforce the formation together. No one can slack off. Do you understand? " Those soldiers said anxiously, "But, Young Master Liu, he..."    

    

Lu Feng said firmly," Young Master Liu is fine. You guys go! " The soldiers could only follow orders. In an instant, Lu Feng's orders spread throughout the city. At this moment, it was a life and death moment. Naturally, everyone had to do their best. In an instant, a powerful formation surged out and reinforced the grand formation of Lu Family Castle. At the same time, those Spiritual Talismen Masters also took out their own Spiritual Talisman. Outside the Lu Family Castle... Waiting for the Great Demonic Beast to fight, the rest of the experts gathered together. They were protecting those weak cultivators.    

    

Liu Fei faced the black shadow alone, he didn't feel any fear at all. Step by step, he stepped forward and took out his Glistening-Sky Primordial Fire. However, his opponent's reaction was very fast. He didn't give Liu Fei any chance to attack. At the same time, the true fire in his hand increased. Lu Ming's strategist could not stand it and said, "No, we can't just watch like this. Everyone, attack together with me!" It was naturally impossible to just watch like this. He immediately brought some cultivators with decent cultivation base to attack. Ordinary cultivators simply had no way of helping. At this moment, they could only pray for protection. At the same time, they nervously stared at the battle. Cold sweat was already dripping down from their foreheads. Many cultivators had doubts about Liu Fei. After all, he was just too young. Moreover, his cultivation base was not even as high as Lu Feng's. He seemed to be a businessman...    

    

Everyone felt that Liu Fei was a little unreliable. However, no matter what, through this battle, they would be able to know Liu Fei's true strength. Therefore, there were countless pairs of eyes in Lu Family Castle listening to Liu Fei. The battle between Liu Fei's Glistening-Sky Primordial Fire and the black shadow was extremely intense. Neither of them dared to let their guard down. The black shadow's cultivation base seemed to be above the fifth level of the Profound Dissolving Stage, and his ability to control the true fire was even more brilliant. Slowly, Liu Fei was suppressed. In an instant, everyone's heart tightened.    

    

Lu Ming's old strategist quickly led a group of cultivators to surround and attack, his speed was very fast. The old man clearly knew that since this black shadow dared to charge in alone, he naturally wasn't an ordinary person, but his own cultivators were nothing special. He could not fight it head on, but he could harass it from within... He kept consuming the black shadow's spiritual energy.    

    

After making up their minds, the crowd directly attacked. The black shadow could not help but snort coldly. "Trying to sneak attack me when you fight me? Hmph, just a bunch of trash!" In an instant, a true flame ignited. It was not an ordinary true flame. The cultivators were unable to resist it either. In an instant, some of them seemed to be in a panic when faced with this great flame. They fled in all directions. As long as they were slightly touched by the True Flame, there was no way for them to escape. In an instant, a series of miserable cries could be heard.    

    

Liu Fei frowned slightly and shouted, "Cut off the place where the true fire burns, and protect your own life!" When those cultivators heard this, they immediately understood what was going on. Although it was painful, they still had to give up. What Liu Fei said was right. If they weren't burned by the flames, there would be no turning back. It was still not too late to cut them off now.    

    

"Humph! Liu Fei, you actually have the time to take care of others? Let's see how you die first!" The black shadow moved with incredible speed toward Liu Fei. In the blink of an eye, Liu Fei grabbed the Taiji Cyan Rainbow Sword in his hand. His killing intent was soaring. Sword Qi gushed out and protected Liu Fei. There was absolutely no way that the black shadow could get close to Liu Fei, but just as he was about to use his sword technique... "Brat, you are too young. You don't even know the puppet technique of our Sorcerer Group!" After saying that, the black shadow vanished.    

    

Then, a biting cold attack came from behind!
