Heaven-defying Upgrade System

Liu Fei followed Zhu Yan'er out. Zhu Yan'er glanced at him. She originally wanted to say that her big brother had a fierce temper, but when the words were about to come out of her mouth, she could not say it. If Liu Fei didn't send her off, she was afraid that neither of them would feel good about it. Therefore, Zhu Yan'er didn't say anything.    

    

Outside Liu Fei's tent, the atmosphere was somewhat cold. Most of the Centaur Clan warriors had gradually entered their dreams. Only a small number of them were still patrolling outside. There was no longer any war, so the security in the camp was somewhat lax.    

    

"Yan'er, we should leave!" A young voice came from the darkness, and then a pair of deep eyes flashed. He looked at Liu Fei and said lightly, "You are the Liu Fei that my sister mentioned?"    

    

"Yes." Liu Fei said faintly. At the same time, he could feel that the Qi of this man in front of him was very powerful. Presumably, his cultivation base was also very powerful. In fact, this Qi was even more terrifying than Chen Xiu's, but judging from his cultivation base... This man's cultivation base wasn't as good as Chen Xiu's. It was just that this man's strength was stronger than Chen Xiu's.    

    

Liu Fei thought for a moment. To have such a powerful cultivation base at such a young age, he must be a genius. Even he felt that there was a huge gap between them.    

    

After that, Liu Fei purposely unleashed his Qi in front of this man. He also slightly activated his Genuine Qi, and the Heaven-defying Strength followed suit. A Qi that wasn't any weaker than this Qi collided with each other. The man was slightly startled, then he looked at Liu Fei and said, "Very good. Although your cultivation base is a little low, your strength isn't bad at all. Your cultivation base seems a little special... En, as expected of the person Yan'er has taken a liking to. "    

    

The person in the darkness said. He looked at Zhu Yan'er and then said to Liu Fei," Liu Fei, if you miss my sister, you can go and find her. "    

    

Zhu Yan'er was slightly stunned. She did not expect that her big brother would be so open-minded.    

    

Liu Fei shook his head, as if he could see the change in Zhu Yan'er's expression. He thought, Silly child, in this world, strength is the most important. If I was just an ordinary person, who would look at me again?    

    

Zhu Yan'er would not think so much. She bit her lower lip slightly. The pain before parting filled her heart. She looked at Liu Fei and lightly waved her hand. She did not even dare to say goodbye. She was really afraid that she would never see him again after saying goodbye.    

    

"Goodbye. Yan'er. "    

    

Liu Fei looked at Zhu Yan'er and her big brother flying into the sky and his heart was filled with melancholy. He didn't know how many expectations he had for this farewell. When would he be able to see his friends in War God Continent again?    

    

Fortunately, Liu Fei's heart was extremely firm, and he calmed down after a moment. After returning to the tent to cultivate for a night, it was already the second day. After that, he got up and bid farewell to Kerim.    

    

At the same time, he also received news that Ku Rugu had been killed by a mysterious expert.    

    

General Kerim just frowned and did not say anything. Miao Chong and the others were indeed shocked by this matter. They all thought that it was those people from Chen Xiu's Yuanmu Sect who came to take revenge.    

    

Think about it, apart from those people from the Yuanmu Sect, who else had the strength to hide Ku Rugu?    

    

Liu Fei smiled faintly. However, just as Kerim was talking about Ku Rugu... Liu Fei had already guessed that it must be Zhu Yan'er's elder brother. After that, he told Kerim about it and the latter heaved a sigh of relief. However, it was likely that Miao Chong and the others would be afraid for a period of time.    

    

After activating the aircraft, Liu Fei headed straight to the center of Tree World. Currently, the center of Tree World was heavily guarded. Perhaps it had been baptized by war. They had also taken sufficient precautions. Liu Fei found an opportunity with great difficulty and slipped in. Because he didn't have any proof of his identity.    

    

The White Wood Clan in the center of Tree World had evolved to a certain extent in terms of civilization, and their management of the overall society had become much more detailed.    

    

After returning to the center of Tree World, Liu Fei only wanted to find out how to leave this place as soon as possible, and whether there were any records about War God Continent, because he felt that he could not afford to waste any more time like this.    

    

However, Liu Fei still miscalculated. When he opened the door of Si Yin's house, he suddenly found his little disciple. He was actually sitting on a chair and chatting happily with Si Yin. In an instant, Liu Fei was in a trance. It was not that he did not want to see Xiao Ruyu again. It was just that he had to do it right now. If he was entangled with her again, who knew what else he would have to go through?    

    

Xiao Ruyu jumped up from the chair happily and shouted, "Master, you are finally back!" Then she ran towards Liu Fei and hugged him.    

    

Liu Fei was shocked in his heart. A conservative girl like Xiao Ruyu. Why was she suddenly so open to him? Furthermore, she was clearly wearing loose pajamas like Si Yin's. Liu Fei could clearly see her. Especially when it was on him, it made Liu Fei feel a little tempted.    

    

Liu Fei's face sank helplessly and said, "Little girl, you are too insensible! Although I am not a gentleman, I am not a frivolous person either. Aren't you making me embarrassed by doing this?" After saying that, his tense face could not help but smile.    

    

"Scoundrel Master!" Xiao Ruyu glared fiercely at Liu Fei and patted his shoulder. Suddenly, she wrinkled her little nose and said, "Your body stinks. Quickly go and take a bath!"    

    

Only then did Liu Fei remember that he had just returned from the war. The smell of blood had not completely dissipated and it smelled a little stinky, so he said, "Okay, wait for me."    

    

After Liu Fei went in, Si Yin looked at Xiao Ruyu curiously and asked, "Xiao Ruyu, what is the relationship between you and Liu Fei?" She was very puzzled in her heart. Furthermore, Si Yin was a few years older than Xiao Ruyu and the questions she asked were somewhat mature. She suspected that there was some kind of hidden relationship between the two of them.    

    

Even if there was, it was not a big deal. After all, the two of them looked similar in age and there was nothing wrong with the match.    

    

"He's my master." Xiao Ruyu said.    

    

Si Yin said helplessly, "He is your master. How can you be so rude to him?"    

    

Xiao Ruyu said with a distressed look, "What is it? Anyway, he is not a bad person. I will call him master. He also treats me as his disciple. What I did just now... It's just to improve the relationship between us master and disciple. You know, he doesn't really like me as his disciple. Maybe it's because I don't like him. Anyway, I feel like he's always hiding from me..."    

    

Si Yin smiled when she heard that. She thought to herself, Little girl, you might really think too much. You're so cute, how could you not be likable? Although Si Yin did not know Liu Fei, she knew that Liu Fei's identity was unusual. Her mind moved slightly and she suddenly thought of an idea.
