Heaven-defying Upgrade System

"This woman is tired of living!" Liu Fei muttered in his heart. Judging from Si Yin's performance just now, she was a little too eager for quick success, which caused her to suffer setbacks again and again. It was not good for a woman to be too strong! Liu Fei thought in his heart. The moment he caught Si Yin, he could not help but glare at her and said, "You don't want your life anymore?"    

    

Si Yin's face suddenly turned red. She did not blush because she was scolded by Liu Fei, but mainly because Liu Fei hugged her. Coincidentally, Liu Fei's hands actually tightly grabbed the huge meatball in front of her chest. What made Si Yin blush the most was that she was grabbed there. It was as if her entire body had been electrocuted. There was an indescribable feeling of comfort and satisfaction.    

    

Liu Fei also did not expect that when he caught her just now, it was completely a hasty action. His hands were placed there by the heavens! How did he happen to eat her tofu? Liu Fei hurriedly retracted his hand, but Si Yin almost fell to the ground. Luckily, Liu Fei helped her up again.    

    

Liu Fei quickly turned his eyes to Lava Warrior and said, "He should not fight anymore."    

    

Si Yin also took the opportunity to look, but she saw that Lava Warrior's waist was missing by more than half. Under his waist, one of his legs was broken. At this moment, Lava Warrior wanted to get up from the ground, but he only had one leg. Even though he got up, he soon fell to the ground because he couldn't stand properly. He could only rely on his arms to slowly crawl on the ground.    

    

"How did you do it?" Si Yin looked at Liu Fei in shock and said.    

    

Liu Fei frowned slightly. He had already put away the Angry Thunder Hammer a long time ago and then replied, "Just hit him like that, and he became like that."    

    

Si Yin curled her lips. This was completely fooling a three year old child. Actually, Liu Fei's meaning was that he did not want her to know. She didn't continue asking. Liu Fei wouldn't easily reveal his secret. After all, in this secret realm... He had broken into this realm by himself. As for how many secrets he had, he had no idea. No one knew. It was undoubtedly foolish to expose his true strength earlier.    

    

Just now, in order to save Si Yin, he had no choice but to use the Angry Thunder Hammer. Actually, after the matter, Liu Fei also felt very regretful in his heart. He blamed himself for being impulsive!    

    

However, the following words made Liu Fei slightly relieved. Si Yin looked at him and said, "No matter what, you saved me twice today. I want to thank you..."    

    

Liu Fei said lightly, "Don't say thank you or not. Friends just help each other. If I help you, if I encounter any difficulties, ___ said. You can also help me. " Liu Fei's words had a purpose. Although Si Yin did not know what she could do to help Liu Fei, if Liu Fei wanted to find out what was going on in this secret realm in the future... He did have the right to ask her about it.    

    

Just as the two of them were talking, a loud bird cry suddenly came from the sky. Liu Fei and Si Yin raised their heads at the same time. Si Yin said excitedly, "It's the people of Scouting Group!"    

    

Liu Fei took the opportunity to look at the huge thing in the sky. It was like a dark cloud. It quickly covered the night sky, and then a strong airflow was stirred up. It slowly descended towards the two of them. When the enormous creature got closer and closer, Liu Fei originally thought that this should be some kind of tamed Demonic Beast. But after that, he could clearly see that it was not a living thing. Its surface was covered with patterns of trees.    

    

If his guess was correct, this thing should be the machine-operated beast mentioned in his hometown!    

    

Liu Fei did not expect this to be their mount! There were too many strange things in this mystic realm!    

    

"This is our Scouting Group's' Green Wood Essence '. It's our main force that has come!" Si Yin said to Liu Fei, "After defeating this Lava Warrior, the higher-ups will definitely reward you for your great achievements!"    

    

Liu Fei was slightly stunned. He smiled and said, "I am just an outsider. I am just passing by. Besides, I am not interested in that. If possible, I would like to find a place to settle down first."    

    

Si Yin almost blurted out, "You can temporarily stay at my house!"    

    

Liu Fei was stunned again. He did not expect this little girl to be so honest.    

    

The people from Scouting Group quickly surrounded Lava Warrior, who was still crawling slowly. Liu Fei looked up. The people of Scouting Group were wearing very simple clothes, which seemed to be made of a large piece of leaf fabric. The clothes were tightly stuck to his body, giving him a high-spirited feeling.    

    

When they saw that Lava Warrior's waist was almost broken, all the people of the Scouting Group looked at Si Yin in surprise. One of them seemed to be the leader of the group. He asked, "Si Yin, you have injured this Lava Warrior of the Black Flame Clan to such an extent. How did you do it?"    

    

"Yes..." Si Yin wanted to say something, but she glanced at Liu Fei and thought of something. She changed the topic and said, "Lava Warrior was already seriously injured. That was why we had the chance to defeat him."    

    

"Sister, something is not right!" The petite girl said with her eyes wide open, "He was still fine before I left..." What she said was the truth, but her gaze turned. She just happened to see Si Yin fiercely glaring at her. Then she heard Si Yin say, "Maybe it was too dark and you were more nervous when you met Lava Warrior. I didn't see it clearly! "    

    

That petite girl immediately shut her mouth. She knew that she seemed to have torn Si Yin's stage apart just now. And Si Yin did not want to report the actual situation to the higher-ups. She was afraid that there was something she could not say. Fortunately, this little girl and Si Yin were like sisters, so she did not continue to speak. Instead, she said embarrassingly, "Maybe I was wrong..."    

    

The leader of the Scouting Group nodded and said, "This matter ends here. You have successfully solved a Lava Warrior. But don't get carried away by your success. Right now, the crisis of our White Wood Clan is getting deeper and deeper. A Lava Warrior like him... The Black Flame Clan has sent many people to invade us. Therefore, we should be on our guard. Si Yin, you guys go and rest for a while. There might be an important task assigned to us tomorrow! "    

    

Si Yin immediately stood up and nodded. From the words of the higher-ups, she already knew that the invasion of Black Flame Clan this time was not a small matter. If Lava Warrior invaded without restraint, it would be very scary. And the most important task wasn't just to deal with Lava Warrior!    

    

After that, the leader of the Scouting Group recorded down a great merit for Si Yin, and rewarded her with ten 'Green Source Crystal Stone'. When Si Yin saw the Green Source Crystal Stone, her eyes almost popped out small stars.    

    

"Is this Green Source Crystal Stone very rare?" On the way back with Si Yin, Liu Fei asked curiously.    

    

At the same time, Liu Fei discovered that the White Wood Clan seemed to be very good at using wood to make items in this secret realm. Just like the flying device called 'Green Jade' that he saw earlier, it was completely comparable to a Flying Sword magic treasure. There was even a huge amount of energy hidden on it. Possess it! If one were to talk about its power, Liu Fei might not know much about it. However, it was definitely not any weaker than a magic treasure.
