Heaven-defying Upgrade System

Furthermore, Si Yin's face turned even redder when she thought about how she was going to lose face in front of Xiao Ruyu. No matter how crazy she was, she could only obediently sit beside Liu Fei, feeling a deep sense of helplessness.    

    

"En, that's right." Liu Fei deliberately moved closer and said teasingly.    

    

At this time, Xiao Ruyu was almost at the edge of fury. Her small mouth curled and said, "Master, do you still want to see how my cultivation is going?" Her tone was extremely dissatisfied.    

    

Liu Fei was slightly stunned and then smiled faintly. He said, "Of course. You can now show in front of me that you have succeeded in your cultivation during this period of time. I want to see how you have learned it, little girl. That way, you won't lose face for your master when you go out in the future." After saying that, Liu Fei narrowed his eyes and quietly waited for Xiao Ruyu to display her cultivation.    

    

"Bang!" Suddenly, a powerful force burst out from Xiao Ruyu's body. A vast and mighty Genuine Qi was shaken out as if a fierce tiger had descended the mountain. Even the surrounding air began to fluctuate. Liu Fei could clearly feel that the force was like a fierce wind that blew across his face.    

    

His eyes suddenly opened and were filled with disbelief. After which, he stared intently at Xiao Ruyu as if he was looking at a stranger. His cold gaze seemed to be able to see through Xiao Ruyu.    

    

This was absolutely impossible. It had only been a few days. Even if Xiao Ruyu was a genius, it was absolutely impossible for her to advance her cultivation to the fifth level of the Mortal Core Stage! Apart from himself, only with the help of the Heaven-defying System could there be a miracle. This little girl was absolutely impossible!    

    

Terrifying, simply too terrifying!    

    

"How is it, have you seen our Little Yu'er's might?" Si Yin saw the shocked expression on Liu Fei's face and couldn't help but say. She was gloating over Liu Fei's misfortune. I thought you would be surprised too? Hehe, I overestimated you!    

    

Liu Fei glanced at her, then stretched out his hand and gestured at her chest. The corner of his mouth curled up and revealed a charming smile to her. "You dare to laugh at me? Could it be that you are not convinced by my judgment just now? Alright, consider it a mistake of my judgment. Now, let me test you again... "    

    

" Rascal! " Si Yin spat at him. At the same time, she nervously took a few steps back and sat very far away from Liu Fei. She was really afraid that Liu Fei would attack her. With Liu Fei's cultivation base, she would not be able to avoid him.    

    

"Hmph." Liu Fei smiled in his heart. He thought to himself, Crazy woman. How dare she challenge me? After thinking for a while, he walked to Xiao Ruyu's side and stretched out his palm. He gently grabbed Xiao Ruyu's wrist as if he wanted to feel something. Xiao Ruyu looked at Liu Fei excitedly and said, "How is it? I didn't let you down, right?"    

    

Liu Fei nodded and said, "Indeed, I didn't let you down, and it really shocked me..." As Liu Fei spoke, his expression suddenly sank. The strength that Xiao Ruyu displayed just now was not at the fifth level of the Mortal Core Stage, or even higher.    

    

"Hehe! Since your disciple is so smart, I will definitely not let you lose face in the future. So from now on, don't you want to teach me properly?" Xiao Ruyu happily puffed out her chest and said.    

    

"Okay!" Liu Fei nodded. Xiao Ruyu was so sincere, and she was willing to put in a lot of effort in her cultivation. If Liu Fei continued to push her away, it would appear that he was a little petty. Furthermore, Liu Fei actually had nothing to teach her. He just wanted to teach her how to interpret martial arts. The rest would depend on her own comprehension. If there was anything she did not understand, she could ask herself.    

    

Xiao Ruyu laughed mischievously and threw herself into Liu Fei's arms. She hugged him, but before she could say anything, she suddenly felt a pain in her chest. Even her head felt a little painful, as if something was causing trouble in her body. His entire body felt like it was going to explode.    

    

Liu Fei's expression changed. Xiao Ruyu, who was in his arms, started trembling. The Genuine Qi that he had just released also disappeared. "Little girl, what happened to you?" Liu Fei held Xiao Ruyu in his arms and observed her condition once again. When he saw this, his expression became extremely ugly.    

    

There was a very powerful Genuine Qi in Xiao Ruyu's body. It was like a ferocious wild beast that was running around inside her body. As for Xiao Ruyu's body, it was already very weak. She was simply unable to withstand the collision of the Genuine Qi. Her current situation was very dangerous. If the Genuine Qi could not be stabilized... You could lose your life at any time.    

    

"What's going on?" Si Yin immediately rushed over like a gust of wind. At this time, her expression was exceptionally serious. Her eyes stared at Xiao Ruyu and revealed a caring expression.    

    

"There is an uncontrollable Genuine Qi in her body. What is going on? What kind of Spirit Pill did you give her?" Liu Fei immediately sensed the origin of this matter.    

    

Si Yin said with a surprised expression, "No. We have only met for less than a day. I don't even know how she cultivated. Why would she give her panaceas to eat?"    

    

After Liu Fei said this, Si Yin, who was also experienced, immediately realized the reason. This was the result of overtaking a spirit pill.    

    

Xiao Ruyu's face was covered with cold sweat and beads of sweat. Seeing this made Liu Fei and Si Yin's heart ache. It was as if a knife was twisting in their hearts. If this kind of pain was placed on the two of them, it might be a little better. But Xiao Ruyu was such a weak little girl. She had never cultivated before. Such a thing had happened in the beginning. It was obviously a little cruel.    

    

"My body hurts so much..." Xiao Ruyu said with a trembling voice, but her voice was not loud and she was getting weaker and weaker. Her eyes were blurred, as if she had fallen into a coma.    

    

Liu Fei picked Xiao Ruyu up and rushed into the bedroom without saying a word. He then gently placed Xiao Ruyu on the soft bed and grabbed her wrist. One Genuine Qi after another was slowly sent over. Liu Fei did not dare to touch his Genuine Qi with that extremely overbearing Genuine Qi. After all, Xiao Ruyu's body was very weak right now. If the two of them collided, it would only cause an extremely terrible damage to her body. She could not bear it.    

    

"Xiao Ruyu, what exactly is going on? You are only at the fifth level of the Human Core Realm, how can there be such a huge amount of spiritual energy in your body?" Si Yin rushed in from behind Liu Fei and asked anxiously. Xiao Ruyu was feeling extremely uncomfortable now. It was already good enough that she could keep her consciousness awake. She had no time to answer Si Yin's question.    

    

"Don't worry about these things for now. The most important thing right now is... Yes." Liu Fei said, "Si Yin, you go and protect the spirit pill in her dantian. As well as the meridians in her body, you must protect them well. I'll try to disperse that Genuine Qi! "    

    

Si Yin immediately nodded her head and said, "Okay!"    

    

So according to what Liu Fei said, Si Yin sat in front of Xiao Ruyu. A pair of hands supported her body and at the same time, began to slowly seep into her body into the Genuine Qi. Liu Fei grabbed her wrist and a Genuine Qi rushed into her body. With a loud bang, it collided with the overbearing Genuine Qi.    

    

"Ah!"    

    

Xiao Ruyu cried out in pain. At this moment, Liu Fei was carefully controlling his strength. If he used too much strength, it would hurt Xiao Ruyu. On the contrary, if he was younger, he would not be able to fight against the overbearing Genuine Qi.    

    

He had to be careful now.
