Heaven-defying Upgrade System

1"Liu Fei?" Loong Gui stared at Liu Fei, thinking that if the little guy was in trouble, it would be reasonable for him to ask for his help. After all, he had told the little guy that he would be in trouble, but he hadn't expected that it would be today. Did Liu Fei count this day? That was impossible, but why would he need his help? Loong Gui asked suspiciously, "Was it really Liu Fei who told you to come find me?" Lu Feng replied, "That's right, Brother Liu Fei is too injured. If you don't intervene, no one will be able to save him!"    

    

Loong Gui couldn't help but become proud as he said, "You guys have good eyes. You know my ability, but what's the benefit of me saving you guys?" He would never do anything that would benefit him even if he lived his entire life. This was the world, and no one was a fool. He wasn't going to help Liu Fei for nothing just because he promised to do so. Lu Feng immediately said: "Old senior, you are currently in the Lu Family Castle area, I can guarantee that you will be responsible for your safety under the Lu Family Castle. You will absolutely not be disturbed unless I, Lu Feng, die!" Lu Feng said in a sincere tone, which surprised Loong Gui.    

    

He actually didn't bargain with him. It seemed like Liu Fei was very important to Lu Feng, but Lu Feng and Liu Fei had only known each other for a short time. Loong Gui could already tell this from last time. So he said: "Little miss, the owner of the Lu Family Castle is your father, right? "You must think it through clearly. What you say does not count!" Loong Gui said coldly. However, when she heard about Lu Chen, Lu Feng's expression changed slightly as she coldly said, "It's me now!" Loong Gui was stunned for a moment as he looked at Lu Feng. However, this girl's expression did not change at all. It was truly shocking. After a while, Loong Gui suddenly sighed: "Forget it, our Loong Gui family can be considered to be very strong, but in the later years of life, we can only live like this. Since it's within your Lu Family Castle, as long as you can give me a guarantee, I can save him.    

    

"Really? You can save Liu Fei! " The excitement on her face could not be hidden. Loong Gui's eyes widened and instantly brought Lu Feng and Liu Fei to his protection. Under his turtle shell, outsiders would not be able to discover anything. Loong Gui said, "Little girl, if I don't save him, he won't die. There is a strange power in his body that won't let him die so easily, but maintaining his vitality isn't an easy task, but when I make a move, I can naturally do it. After all, Loong Gui's medical skills are quite powerful!"    

    

"I believe you!" Lu Feng said, "Uncle!"    

    

Liu Fei was then placed on a turtle shell, the mysterious shell of the Loong Gui tribe, which emitted a strange fragrance. There were traces of erosion on the shell, as if many stories were hidden inside. At the same time, the tortoise shell emitted a special spiritual energy that could actually be used to temper a cultivator's muscles and bones. Liu Fei felt as if his body was thrown into a furnace by a blacksmith and refined by the power of his body. Lu Feng said from the side, "This turtle shell seems very special!" Loong Gui said: "Of course, this is a magical equipment cultivated by Loong Gui, a huge Loong Gui of our Loong Gui Clan with a million years of cultivation, and can be said to be a godly weapon for treating injuries. Many human cultivators kill our Loong Gui Clan to get this thing, if I use the Demonic Beast's inner core, the effect will be even stronger!    

    

Lu Feng widened her eyes in shock. She couldn't believe it. She didn't know how powerful the effect would be, but Loong Gui definitely had the ability to kill a dead person. "With great effort, Liu Fei opened his eyes. With the help of the turtle shell, his consciousness gradually recovered its strength." "Don't move, rest well. I don't know what happened, but it's hard to imagine what kind of person you were actually injured to such a degree!" Loong Gui said.    

    

Liu Fei nodded, gave Loong Gui a grateful look, and closed his eyes. Lu Feng, who was standing beside Liu Fei, quickly asked, "Uncle, is Brother Liu Fei's injury really that serious?" Hehe? Serious? Let me tell you the truth, if it wasn't for the special power in his body maintaining, and if I didn't save his body a few hundred times over, would he still be able to make it to see me? Let me tell you, even a higher level alchemist can't do anything to him, this guy has almost completely destroyed his body, his body has gone through countless tempering, and he is already very strong, but this brat can still do this to him, what a pity! "    

    

As Loong Gui said this, Lu Feng suddenly felt a little uncomfortable in her heart. Could it be that Liu Fei was really hard to treat? However, Loong Gui followed up, "But don't worry, he's just a cultivator of Heavenly Core Stage. The difficulty of treating him can be reduced a bit, so just leave it to me. Little girl, you don't need to worry!" Lu Feng nodded. Standing beside Liu Fei, she said, "Old Senior, I won't get in your way if I stay here, right?" Loong Gui chuckled, "It's alright."    

    

"Harmony of Yin and Yang!" Loong Gui suddenly shouted and instantly dropped two turtle sculptures from above. One on the left and one on the right, they pressed down on the two sides of Liu Fei. One was black while the other was white. Under Loong Gui's control, Liu Fei's body slowly merged with the light emitted by the two tortoise sculptures. At the same time, the tortoise began to vibrate with the rhythm of the light. Lu Feng stared blankly at Liu Fei. Under the balance of Yin and Yang between the two tortoise carvings, Wu Tie's body was actually recovering bit by bit. Lu Feng couldn't help but be pleasantly surprised.    

    

At this moment, the entire space shook. Lu Feng didn't know if this was the place where Loong Gui's turtle shell was protected, but it looked like Loong Gui wasn't feeling well either. He should have already done his best. "AHH!" At this moment, Liu Fei suddenly let out a furious roar. His body instantly stood up and was wrapped by the spirit energy of the two tortoise sculptures. Sigh! What exactly was going on with Liu Fei's body? It felt as if there was a powerful force protecting him, but it couldn't be forced into it by others … "Just what is this …" Loong Gui shouted in surprise.    

    

No matter what treatment method he used, it would not work, just like before. But now, Liu Fei's Heaven-defying Strength was getting stronger and stronger, so even someone as strong as Loong Gui could not do anything about it. Liu Fei completely felt despair. However, at this time, Liu Fei suddenly felt a burst of coldness in his chest. Suddenly, a blue shadow drilled into his body. "Lan Feng?" Liu Fei was slightly shocked in his heart.    

    

At the same time, he stood up and said to Loong Gui, "Old senior, I'm afraid you can't do this, your treatment has improved a bit, but I'm afraid it won't work if we continue. I think I can recover myself, I'll recover in a month."
