The Nebula God King of the Heavenly Demon Clan named Prajna Mi, in terms of status and cultivation strength, is definitely at a higher level than Shen Buku. Among the countless Heavenly Demon clansmen in the Xuanwu World, that is the only one who exists like the Wuque Demon Lord. Prajna Mi has such a cultivation status, but she is at odds with Demon Lord Wuque. In addition, she has never found a suitable body, so she has no choice but to choose to sleep for a long time. But who would have thought that it didn't matter that he was sleeping, but he was unable to fight back and was imprinted on his soul by Yuntu, becoming a traitor to the Demon Clan and Yuntu's most loyal thug. Prajna Mi has a higher status than Shen Buku, and the secrets she knows about the Demon Clan are of course more secretive. This underground palace was originally the dormitory of the Demon King Wu Que, and was the core of this demon cave. Only Prajna Mi's status could possibly know one or two of its secrets. "But even with Prajna Mi's cultivation status, he still doesn't know what is hidden behind this most secret door. Everything he said is just his private speculation. Under Yun Tu's repeated questioning, Prajna Pond thought over and over again for a long time, and finally answered with no confidence at all: "Besides the identity jade token of the perfect demon himself, there is probably only one way to open this door. " "What method?" "It is said that there is a very secret core mechanism room in this underground altar, which controls all the mechanisms and formations in this underground altar. Although this door is unbreakable, it relies on the mechanisms and formations. The power of magic. Just find the core mechanism room and find a way to break the mechanism and the formation on this door. " "Where is the core mechanism room?" " Under that big altar, it is said that the entrance to the core mechanism room can be found by destroying the big altar." Upon hearing this, Yuntu went straight to the big altar with countless natal lamps burning. After ten breaths, standing in front of the large altar illuminated by countless black and red demonic flames, Yuntu did not hesitate at all. With a flip of his wrist, the Xuan Mingli Fire Sword was instantly in his hand, and the brilliant wood spiritual power was like a blazing flame. , soaring into the sky! "Whoosh!" A majestic sword energy. Howling, it struck directly at the large altar carved from huge black jade. "Boom!" With Yuntu's current level of cultivation, such an altar, which is extremely sacred in the eyes of countless demon clan members, turned into dust all over the sky right before his eyes! Together with the countless natal magic lamps, they turned into nothingness at the same time! "Boom!" Hundreds of thousands of natal lamps were extinguished instantly, and the biting ice in the entire Demon Cave disappeared without a trace in an instant. At the same time, on the base of the high altar. As expected, Yuntu saw a narrow, dark entrance that could only accommodate one person. His tall figure swayed slightly and disappeared into the entrance. In the entrance is a quiet, deep and narrow passage that is a hundred feet long, spiraling all the way down. At the end of the passage is a huge stone chamber with a diameter of more than ten feet. Surrounding the four walls are the twinkling lights of countless mysterious formations, seals and spiritual patterns. This is like the light of stars all over the sky combined. It is the key and core of the mechanisms and formations that support the entire underground altar! Having found this key place, Yun Tu was not at all excited. Instead, the extremely complex and mysterious combination of talismans, seals and spirit patterns made him feel dizzy just looking at it, and he wanted to crack it. There is simply no way to start. After hesitating for a moment, Yun Tu raised his brows sharply: "I can't care about that anymore. Destroy them all before we talk!" Before he could finish his words, Yun Tu slashed out with the Xuan Mingli Fire Sword in his hand, "Chi Chi Chi!" The sword energy surged wildly through the stone chamber, destroying everything inside in just two breaths. "Crack, boom!" Once the mechanism formation was completely destroyed, the underground cave that had existed for countless thousands of years suddenly appeared to be unsustainable, and there were heart-wrenching cracking and grinding sounds everywhere, as if It could completely collapse at any time. Large and small gravels and soil fell down like raindrops, and a thunderous sound echoed throughout the cave. Underfoot, there was violent shaking like landslides and ground cracks. It was only then that Yuntu realized that he had been reckless and seemed to have caused a big disaster! This place may completely collapse at any time, time is really tight! Without any time to think about it, Yuntu swept all the way back to the last door at the fastest speed, and said to Nangong Youdao and Li Chunfeng who had been guarding here: "How is it? Can you break open this door now?" Nangong Youdao and Li Chunfeng, with thousands of sword energy in their hands, were furiously slashing towards the door, leaving behind deep ravines and cracks. LostWithout the protection of formations and mechanisms, although this door is still strong, it is no longer so unbreakable. Just listen to Li Chunfeng say: "Give us half an hour, no matter how thick and strong this door is, we will definitely be able to break through it!" When Yun Tu heard this, he immediately replied anxiously: "This place has been completely destroyed. The organs and formations have been completely destroyed." The law may completely collapse at any time. How can we still have half an hour? If we are buried here, we will be in big trouble!" As soon as he finished speaking, Yuntu stabbed out the Xuan Mingli Fire Sword that he had been holding in his hand without hesitation. . Legendary weapons are legendary weapons. No matter in terms of power or sharpness, they are by no means comparable to the soldiers in the hands of Nangong Youdao and Li Chunfeng! "Chi!" There was a crisp sound, and the Xuan Mingli Fire Sword, shining with divine light, cut into the door like tofu, all the way to the end! "Break it!" Yuntu roared loudly, and his whole body flashed with spiritual light. The Xuanmingli Fire Sword in his hand suddenly spun, and it immediately made a big circle on the door! "Bang!" Yun Tu raised his leg and kicked hard while sheathing his sword. "Bang!" There was a loud noise, and a large hole with a diameter of five feet in the door immediately broke open. The pierced portal blew out a biting cold air full of destruction and filth, causing the three Yuntu people in front of the portal to tremble involuntarily! The demonic energy coming out from behind this portal is a hundred times stronger than anywhere else in this demonic cave, and has reached a suffocating level! Looking at the dark and gloomy hole, I heard Nangong Youdao and Li Chunfeng say at the same time without thinking: "Let me go in first to find out what's going on!" With that said, this pair of peerless pairs prepared to rush in, but they were unexpectedly blocked by The cloud map in front of him blocked the entrance. "You guys stay here and I'll go in!" Before the two of them could say anything, Yuntu's back swayed slightly and disappeared into the hole. And at the same time that Yuntu broke through this portal, Demon Lord Wuque, who was hundreds of thousands of miles away and still sitting on the golden chariot with a cold face, suddenly frowned and his face changed. Shen, with a sudden movement in his mind, he subconsciously touched the Sumeru Ring, and a palm-sized black jade tablet came out from it. This jade token of unknown material is completely different from other jade tokens. It is neither gold nor jade, nor dead wood. I am afraid that the material alone is a rare treasure. But at this time, this black jade medal was broken into countless pieces and turned into a pile of useless debris! "What? This!" Demon Lord Wu Que stared at the jade token in his hand in disbelief, and exclaimed in an almost screaming voice: "The Holy Demon Token refined by Master himself actually broke. , What is going on? Could it be that someone dared to secretly enter the palace and break through the door? How is it possible, how is it possible!" Demon Lord Wuque's face changed wildly, and all kinds of thoughts flashed in his mind. Then he passed by and roared angrily: "He Fang Xiaoxiao, how dare you be so bold, how dare you be so unscrupulous! I swear to refine your souls and crush your bones into ashes!" Before he finished speaking, Demon Lord Wuque's handsome figure His figure soared into the sky, and he was about to tear the void apart! But what time is it now? It was the juncture of the decisive battle between hundreds of thousands of Heavenly Demons and the Star Temple. He, the commander-in-chief, seemed to have suddenly left without saying a word. What would happen to these hundreds of thousands of Heavenly Demons? Who will lead? Who will direct? If this Demon King of Perfection really leaves here, the entire demon army will be completely defeated, which is almost a doomed outcome! Upon noticing Demon Lord Wuque's unusual move, the demigods who were guarding him couldn't help but change their expressions. They hurriedly moved their bodies to follow closely. They were extremely frightened and said with great respect: "Master Demon Lord, this What's going on? If you leave like this, what will happen to these hundreds of thousands of troops? You must think twice!" The figure of the Wuque Demon Lord couldn't help but turn around and come back to watch. Looking at the anxious battle situation, there was also a hint of hesitation between the extremely furious expressions. "Lord Demon Lord, we are at a critical moment right now. Without your presence, we will never be the opponents of the Star Temple! No matter how important the matter is at the moment, we must wait until the winner is decided!" "Lord Demon Lord, heaven It's a big matter, and I have my subordinates to share your worries! As long as you stay here to command the army, I'm willing to take this trip for you!" The rage in Demon Lord Wuque's eyes gradually calmed down, and while the corners of his mouth twitched, he felt cold. Incomparably, he said: "I don't know why Fang Xiaoxiao sneaked into our clan's underground altar while my demon army came out to fight at the gate of the Star Temple!" "What?" Hearing what Demon Lord Wuque said, everyone present was present All demons cannot help butGotta be surprised at the same time! "How is this possible? The underground altar of our clan is the most secret place. Even ordinary people in our clan don't know this place. How can outsiders know about it? Moreover, the underground altar has layers of defenses, so it is impossible to rely on brute force. Break!"
