"You can still hold on? Were you just faking it?" Zhao Kunlun stood still, his eyes fixed on Zhou Peng in the distance, feeling very shocked in his heart. This place was already 350 meters deep into the cave, and an ordinary person's body could not bear it at all. Just now, Zhou Peng showed a pained look at the 300 - meter mark, but now, after going dozens of meters deeper, he showed no discomfort at all. Zhao Kunlun was certain in his heart that Zhou Peng had definitely been faking it just now. After cultivating in the Scarlet Refinement Cave for several years, he was very familiar with everything in the cave. The Scarlet Refinement Cave was bottomless. Except for the entrance, which was artificially excavated, everything inside the cave was naturally formed. It was rumored that Scarlet Refinement Peak was where the spiritual veins of Beyond - the - Heavens were located, and it was the place with the most abundant Geng Metal Qi. It was bottomless, and no one had ever entered the deepest part. Rumor had it that the innermost part of the cave led to another world, but no one knew where it was. These were not the key points. The most crucial thing was that the pressure felt even half a step apart was different, and the Geng Metal Qi felt with each step forward was also different. When an ordinary person with low cultivation entered the Scarlet Refinement Cave, their internal organs would be instantly ruptured by the Geng Metal Qi and they would die. No matter how powerful one was, even a super - strong person at the Great Perfection Realm, they had to proceed step by step. Entering 300 meters at once was an unprecedented thing. Not only did Zhou Peng not feel any discomfort, but he was also relaxed and at ease, coming and going as he pleased. "How could this be? It's simply impossible..." Zhao Kunlun was shocked in his heart, and then he said, "Whether you were faking it or not, you are definitely going to die today. Sacred Hall." "Usually, those who say others will die will die earlier themselves." "Zhao Feng was, Zhao Changkong was, Zhao Chang'an was, and so will you." "Look, this is his fate." Zhou Peng took a step forward, glanced coldly at Zhao Jianyi lying on the ground with his chest pierced, and said faintly. A powerful aura faintly emanated from his body. Zhou Peng didn't dare to underestimate Zhao Kunlun. At the second level of Breaking - through - the - Sky, his strength was very formidable. Zhao Chang'an died because of his own caution, but Zhao Kunlun would not be like that. Every time he made a move, he was bold and decisive, killing with one strike and not giving his opponent any chance. A person like him would go all out from the start. With his cultivation at the second level of Breaking - through - the - Sky, Zhou Peng could not possibly be Zhao Kunlun's opponent. Now, the little devil in his Dantian was severely injured, and he could not use the Grand Manipulation Technique again in a short time. He could only rely on himself. Unconsciously, the pressure increased drastically. Compared to Zhou Peng, Zhao Kunlun was the same, or even felt more pressure. A person who could kill Zhao Chang'an, who was stronger than him, was extremely difficult to deal with no matter how weak his strength was. However, Zhou Peng had to be killed. "Boom!" After thinking about it, Zhou Peng couldn't find Zhao Kunlun's weakness. His heart tightened, and he decided to strike first and launch a sudden attack. He activated the Heaven - Overturning Seal with his True Qi. Since he could kill Zhao Jianyi at the ninth level of Samsara with one move, even if he couldn't kill Zhao Kunlun, he would surely be able to severely injure him. As soon as the Heaven - Overturning Seal came out, a powerful force burst out around it. Zhao Kunlun's eyes showed surprise, and he was fearful in his heart. Immediately, he used the Geng Metal Qi to protect his whole body and suddenly retreated several steps. The Heaven - Overturning Seal flickered in the air, and the dragon eyes flashed. A red light shot out, and a sharp arrow rushed out violently... At the same time, Zhou Peng's hands were empty. Under the 128 - times attribute boost, the Dragon - Elephant Taixu Sutra was suddenly activated, and a dragon's roar suddenly rang out. "The dragon - elephant leaves its body, suppressing the world..." "Darkness Divine Art..." The dragon's roar suddenly rang out, echoing in the abyss of the cave for a long time, constantly reverberating, just like tens of thousands of giant dragons roaring simultaneously. It was extremely shocking to the mind and soul. To kill Zhao Kunlun, Zhou Peng had to use three skills to stack and combine them into a towering pillar. Only in this way would he have a chance to kill Zhao Kunlun; otherwise, it was impossible. Although the power of the Heaven - Overturning Seal was powerful. It might be a bit difficult to injure Zhao Kunlun at the second level of Breaking - through - the - Sky, so Zhou Peng used the Heaven - Overturning Seal as a feint attack, and the real attack was the Dark Pillar. Once the Dragon - Elephant Taixu Sutra was activated, the entire Scarlet Refinement Cave would surely be in chaos, startling the other three Zhao disciples, but Zhou Peng was not afraid. As long as he killed Zhao Kunlun and obtained 200,000 Qi points, it would be enough to deal with the other three. If he was going to kill, he would kill them all to avoid being distracted from cultivation. Once they were dead, the matter of the Dragon - Elephant Taixu Sutra would never reach Long Xiaotian's ears. In this world, perhaps only Long Xiaotian knew the existence of the Dragon - Elephant Taixu Sutra. As for the others in the cave, they didn't know who made the dragon's roar at all. Once the three skills were activated, their powers quickly stacked and intertwined. For a while, everything in the cave was shocked by the powerful aura emanating from Zhou Peng, and even the Geng Metal Qi shrank slightly. Zhao Kunlun's face changed. The aura emanating from Zhou Peng made him involuntarily feel a sense of fear. He didn't expect that Zhou Peng had hidden such a powerful skill. His brows furrowed. Facing the red - light sharp sword released by the Heaven - Overturning Seal, he shouted loudly, "Sword, come out..." "Buzz..." Before the sword was drawn, the sword's humming sound rang through the sky. With a fierce shout, the long sword on his back flew out like a mad demon and slashed at the red - light sharp sword. "Clang!!!" A dazzling spark was struck in the darkness. The red - light sharp sword dimmed a little, its speed decreased slightly, but it was still full of murderous intent and rushed towards Zhao Kunlun's vital point like lightning. Zhao Kunlun slashed with great effort, only reducing the speed of the red - light sharp sword a little. His heart skipped a beat, and he retreated several zhang again and slashed with great effort once more. "Boom!" The red - light sharp sword dimmed a little more, and its speed dropped again. Zhao Kunlun sneered coldly and retreated again. After several repetitions, the power of the red - light sharp sword was less than one - tenth of its original power. It would be scattered and disappear after two more times. Zhou Peng didn't expect that the power released by the Heaven - Overturning Seal was so powerful that it almost drove Zhao Kunlun into a desperate situation. However, now that Zhao Kunlun could already fend off the red - light sharp sword, it was impossible to kill him with the power of the Heaven - Overturning Seal. Now, he could only rely on the Dark Pillar. With this thought, Zhou Peng didn't hesitate. He took a step forward, kicking up a thick layer of dust, increased his speed, and rushed forward like a black shadow. The Dark Pillar was composed of flames and would not be restricted by space. When Zhao Kunlun completely defused the red - light sharp sword, Zhou Peng's Dark Pillar in his hand, as if it were a solid object, slammed down heavily, and he shouted loudly, "Damn it, go to hell." The Dark Pillar possessed three extremely powerful forces. When Zhou Peng was at the Refining Gang Realm, all his skills were still at level one, and the illusory power could already force Yao Qing at the Entering - the - Void Realm to death. Now that his supernatural power was at level six of Rampage, and the Dragon - Elephant Taixu Sutra had also reached level three, the illusory power was extremely powerful. For a while, strong winds blew in the cave, and fierce winds raged. The Geng Metal Qi protecting Zhao Kunlun's body constantly contracted. Some of it directly turned into powder and began to dissipate slowly. "Sword Dance in the Nine Heavens..." "Kill..." Zhao Kunlun's brows furrowed deeply. He shouted angrily, and his long sword suddenly transformed into a sword shadow one zhang thick. The sword shadow was like a solid object and directly slashed at the Dark Pillar. "Boom, boom, boom..." All around was chaos! In the dimness, three figures approached from far away...
