Xiang tianxiu, Lu Luo, and the others gritted their teeth, but they couldn’t do anything. They could only retreat step by step. A rank 7 martial artist versus a rank 8 martial artist. The other party wasn’t some unknown rank 8 martial artist. They were all famous figures on the global rank 8 list. Xiang Tianxiu and the others had no chance of winning at all. It was also because of this that the other party had this cat-and-mouse mentality. They wanted to see fear on Xiang Tianxiu’s and the others’faces through this neither fast nor slow encirclement. However, they were disappointed. Showing fear in the face of the enemy would make the enemy even more excited. Xiang Tianxiu and the others had long known this. Therefore, not only did everyone not have the slightest bit of fear, they even gritted their teeth and glared at the Takama-ga-hara martial artist. They wished they could eat his flesh and drink his blood! “How boring. Kill them all. Don’t waste time.” The rank 8 warrior in the lead seemed to feel bored and didn’t want to continue playing. He waved his hand, indicating for the others to make a move. “Hey!”The others grinned and pounced on him. At this moment, a loud dragon’s roar pierced through the silent air. The Takama-ga-hara warriors were shocked. This sound was so close. Was it a powerful monster approaching? In the next moment, a terrifying thunder breath fell from the sky and directly drowned the Takama-ga-hara warriors. These warriors didn’t even have the ability to resist and instantly melted under this dazzling thunder light. The dazzling light also made Xiang Tianxiu, Lu Luo, and the others unable to open their eyes. They had no choice but to close their eyes. When they opened their eyes again, the dozen or so Takama-ga-hara warriors surrounding them were already gone. Their life forms had turned from humans into a pile of dust. When the breeze blew, they flew everywhere. Whoosh! Everyone looked up and saw a giant lightning dragon flapping its wings and disappearing in an instant. Xiang Tianxiu was extremely shocked. “It was that Lightning Dragon that saved us?” Lu Luo was also stunned. “The monsters can differentiate between factions? That’s not right. We have killed quite a number of monsters too.” The others looked at each other with dumbfounded expressions. Monsters had always been synonymous with chaos and disorder. They would kill anyone they saw without mercy. That Lightning Dragon could instantly kill a tier 8 martial artist with a single skill. It was obviously a Tier 9 monster. Why didn’t it also take care of the construction department’s martial artists? They couldn’t figure it out. No matter how hard they tried, they couldn’t figure it out. “Perhaps… It has gained sentience?” This question arose in everyone’s hearts. However, they did not have the time to guess the answer to this question. Since the people surrounding them were already dead, there was no time to waste if they did not run now! In the distance, Lin Xuan retracted his gaze. “That’s it. I won’t appear. Just get the tier 9 dragon to help.” After controlling the Lightning Dragon to help Xiang Tianxiu and the others escape, Lin Xuan continued his tier 8 promotion quest. Every 18 minutes, he would drink a bottle of super poison potion, keeping his tenacious hp below 50% . Time passed quietly. His kill count also increased rapidly. 30,35,50.. Three days later, he stood on the corpse of a Venom Wyvern and laughed at the sky. “100!” “Class advancement requirement met!” “Now, I’m only missing five materials to become a secret realm king.” On his way here, Lin Xuan encountered several territories belonging to Secret Realm Kings. They were all super powerful tier 7 or Tier 9 monsters. As he only had 50% hp, he did not rush in just to be on the safe side. However, now that his class advancement requirement had met, there was no need to keep his HP below 50% . Without the suppression of the super poison potion, his HP skyrocketed like a spring bamboo shoot after a rain. In just a few minutes, his HP was fully recovered. “Kill!” Lin Xuan turned around and found the valley, standing together with the Frost Dragon King and its five spouses. More than an hour later, all the Dragons in the valley had died. Lin Xuan dug out a tooth from their bodies. This tooth was shining with golden light, and it was the material for advancing to the king level of the Mystic Realm. “Next!” Lin Xuan excitedly rushed to the next location. The second, the third, and the fifth! When night fell, Lin Xuan obtained five materials for advancing to the king level of the mystic realm. As usual, he found a safe place and asked the Lightning Dragon to stay nearby. Then, he opened the data panel. He took a deep breath and thought of the information he had read in the books. From level 1 to Level 6, there were no abnormal signs. But from level 7 to level 8, and from level 8 to Level 9, there would be abnormal signs. The contents of the abnormal signs were all strange, but they were mostly related to the class. If it was a lightning teacher like Xiang Tianxiu, the abnormal sign might be a lightning dragon or a lightning eagle. If it was an ice blade like Ye Yuqiu, the upgrade might have been a giant sword soaked in frost. The color of the class was the same as the color of the upgrade. “I heard that the bigger the upgrade, the better. The bigger the upgrade, the stronger the overall strength. I wonder how big I’ll be.” “It shouldn’t be too big, right? If it’s too big, it’ll be too scary. It might attract others to covet it.” Lin Xuan thought about the pros and cons of advancing. The pros were very simple. He had become stronger. After he became a rank 8 fighter, he could at least defeat and kill ordinary fighters below rank 8 or rank 6. If the other party was a seeded fighter nurtured by various organizations, it wouldn’t be a big problem for him to fight one or two levels higher. But the cons were also right in front of him. If he made too much noise during his advancement, it might attract unnecessary trouble. At that point, he could be completely exposed! Not only would he reveal his location, but he might even reveal his connection to the clones.
