Venerable Martial Emperor

　　If it was any other place, Xu Feng would never take the initiative to take out his martial arts. But now that he was in the Demon King's Mansion, it was only a matter of time before he took it out. He might as well take it out openly like Demon King Mo Yao. There was no need for the Demon King to take the initiative to speak in such an awkward manner.    

　　"It's useful, it's too useful!"    

　　Raging Fire Demon King's eyes were filled with pleasant surprise. Even his silly and silly appearance had disappeared. He was so happy that he looked like a child.    

　　"It's good that it's useful. I was worried that these things are too useless. The two of you are not interested in them!"    

　　Xu Feng scratched his head in embarrassment and said softly.    

　　In fact, in the outside world, the martial arts that he took out were not precious at all. Compared to the treasure land here, it was like a drop in the ocean.    

　　It was just that there were no martial arts that had appeared here. It had a certain effect on their cultivation, which was why it was so precious.    

　　"No, we need to study these Martial Arts. I believe that we will be able to create the Martial Arts that are most suitable for ourselves soon!"    

　　Compared to the Demon Cultivator outside, Mo Yao and Raging Fire Demon King both knew that what was suitable for them was the best. Therefore, sharing these martial arts was nothing to them.    

　　"Um... Seniors, Xu Feng has a few questions. I don't know if I should ask them."    

　　Seeing that there was not much difference between them, Xu Feng mustered up his courage and spoke. After all, the reason he asked the Demon King to look for him was because he wanted the treasure mentioned by the Blue Beauty Fire.    

　　"Speak, as long as it's something we can do, we will try our best to satisfy you!"    

　　Mo Yao's mood was obviously not bad, and he agreed without thinking.    

　　"I want to know what kind of place this is, and why there's such a dense Spiritual Force of Heaven and Earth here, and why I've never heard of any martial arts before, but all of you are able to cultivate to such a powerful extent."    

　　The questions that had been plaguing him for a long time had appeared in his mind one by one. He had actually opened his mouth. Xu Feng had no intention of hiding it. He spoke in one breath and looked at the two demon kings nervously.    

　　These questions, especially the one that involved the Spiritual Force of Heaven and Earth, could be said to be a secret of this world. If these two Demon Kings were unhappy, they would very likely be killed here.    

　　"Young Fellow Taoist Xu Feng, don't be so nervous. We won't do anything to you!"    

　　Mo Yao chuckled and said first. He paused for a moment. He continued, "We don't know what this place was originally called, but after the four legs of Four Demon Kings were established... We gave him a name. We named this place... A different world! "    

　　" Even you guys don't know what this place is called? "    

　　Xu Feng was stunned. This was simply too inconceivable. However, the name was quite appropriate. After all, this place was isolated from the outside world, and it was a world of its own. It wasn't excessive to call it another heavenly passage.    

　　"This place has existed for a very long time!"    

　　Raging Fire Demon King said in a deep voice, but Xu Feng could hear the meaning behind it.    

　　They had said some unimportant things, but they did not mention a single word about why the Spiritual Force was so dense here. Clearly, they did not want to tell Xu Feng about it.    

　　One should know that Xu Feng had come for the sake of obtaining the supreme treasure inside. Now that they didn't tell Xu Feng any news about it, it made Xu Feng feel awkward. If they were to say it directly, Xu Feng was still worried that he would be killed by them.    

　　After all, whether it was Demon King Mo Yao or Raging Fire Demon King, they were both incomparable experts to Xu Feng.    

　　"Forget it, forget it! I'll tell you all about it!"    

　　Seeing Xu Feng's expression, how could Mo Yao not know what Xu Feng was thinking? After letting out a long sigh, he continued, "Originally, this was a medicinal garden. According to the rumors, this medicinal garden looked... It was founded by a man named Shennong!"    

　　"What!? Shennong!?"    

　　After hearing this, Xu Feng immediately stood up and truly lost his composure for once.    

　　Shennong was Great Monarch Shennong. Before becoming an Emperor, the world had already called him Shennong. Thus, this Shennong title was a very long time ago.    

　　"Yeah, what's wrong?"    

　　Demon King Mo Yao was even more surprised by Xu Feng's surprise.    

　　He didn't know how powerful Shennong was, but he knew that someone had created such a place.    

　　"No, it's nothing!"    

　　Xu Feng forced himself to calm down and let Demon King Mo Yao continue. Only then did he slowly understand this place.    

　　This place was indeed a nameless land, and it was also a medicinal garden. However, after countless years, many of the spiritual herbs had withered away, leaving only a few spiritual herbs behind.    

　　Of course, after countless years of nurturing, the Spiritual Force in this world had gradually become denser. And, the most precious thing in this world was an ancient tree.    

　　According to the legends, that ancient tree had been born here ever since the appearance of this world. The withered spiritual herbs' Spiritual Force were all absorbed by him. After that, it was released and spread to every corner of the surroundings. It was to provide enough Spiritual Force for the Demon Cultivator.    

　　"Just how powerful is the Spiritual Force of this ancient tree!?"    

　　After listening to this, Xu Feng couldn't help but suck in a breath of cold air. How many Spiritual Force of Heaven and Earth had this ancient tree absorbed from countless years ago to be able to supply such a large area with such powerful Spiritual Force?    

　　Furthermore, in this area, the Spiritual Force was so dense that it was like a waterfall or a hot spring...    

　　"I wonder if it's possible to let me experience this ancient tree?"    

　　Xu Feng looked at the two Demon Kings nervously and asked in a soft voice.    

　　Before coming here, he had absolutely fantasized about it. But after hearing this, Xu Feng became somewhat uneasy. Because he could even imagine the preciousness of the ancient tree. One! It might even affect the entire world here.    

　　"This... I'm afraid it's going to be difficult!"    

　　Just as Xu Feng was thinking, after Xu Feng told him his request, Mo Yao was stunned for a moment and said in a difficult manner.    

　　Sighing, Xu Feng already had a feeling in his heart. Although he felt a little regretful in his heart, he quickly adjusted himself and said that it was fine.    

　　So what if it was related? He couldn't rush forward and tear the two demon kings into pieces.    

　　"This won't do. Xu Feng, you have to go and take a look. Otherwise, I will have to waste my efforts to bring you all here!"    

　　Blue Fire's dissatisfied voice was heard. It was very soft and weak, but Xu Feng pretended not to hear it and continued to talk to the two demon kings.    

　　No matter what, he had to go and take a look at that ancient tree. Otherwise, even he wouldn't give up, let alone the blue fire.    

　　"Little friend Xu Feng, you can cultivate here, but let me give you a piece of advice. It was better not to approach the ancient tree. The devouring ability of the ancient tree was extremely strong. If you are not careful, it is very likely that you will be devoured as well. Even us demon kings do not dare to get close! "    

　　Although Xu Feng hid it well, Demon King Mo Yao seemed to have noticed something and said something.    

　　"Thank you for your reminder Demon King!"    

　　Nodding his head, Xu Feng said in a low voice. If he wanted to go, he had to go in secret. He couldn't let them know. In any case, during the conversation just now, Xu Feng already knew the approximate location of the ancient tree.    

　　After chatting for a while, the Inferno Bull Demon took some martial arts and left the cave. Xu Feng and the others stayed in the cave.    

　　The life of the Demon Cultivator was very simple. The sky was the bed and the earth was the blanket. In any case, there was no need to worry about anyone finding trouble with him in this place.    

　　That night, Mo Yao had comprehended all the martial arts and started to wave them around in this world.    

　　Xu Feng also gave up on sleeping, and quietly watched the Demon King in the sky from the side.    

　　Such an expert, with just a raise of his hand and a lift of his foot, waved the Great Dao of this world. The aura emitted from it was slightly more powerful than the aura that Qingqing had unleashed. It was even stronger, allowing her to observe the cultivation of such an expert. It was beneficial to Xu Feng as well.    

　　The following days became ordinary. Xu Feng would observe Mo Yao's cultivation from time to time. Then, he would gain enlightenment and sit cross-legged on the ground to cultivate. When he encountered a problem that he did not understand... He would also humbly ask Mo Yao for guidance.    

　　Xu Feng was improving, and Mo Yao was also improving. After about ten days, he had thoroughly studied the martial arts Xu Feng had given him, and had even created a martial art that belonged to him. Its power was astonishing.    

　　In Xu Feng's opinion, the martial art Mo Yao had created was at least a Low-grade Celestial Level martial art. It was truly amazing.    

　　However, sometimes, Mo Yao would ask shamelessly, and would discuss about martial arts with Xu Feng. Although their cultivation levels were different, they had their own unique understanding of martial arts, and they could often infer three things from each other.    

　　"Xu Feng, you really are a genius!"    

　　Every time they finished talking, Mo Yao would praise Xu Feng. Not only because of martial arts, but also because of his knowledge in cultivation. Xu Feng also had a certain level of knowledge, and he didn't look like a late Essence Returning Stage warrior at all.    

　　Every time this happened, Xu Feng would be very humble, but in fact, he was quite happy in his heart. After all, not everyone could be praised by Demon King.    

　　Soon, the Demon King of Fire also received the news. Three of them had come to Mo Yao's cave for two days, and had invited Xu Feng to his cave to discuss martial arts with him.    

　　Regarding this matter, Xu Feng naturally wouldn't reject it. This way, he would be able to broaden his horizons, so why not?    

　　As the saying goes, there are people who are happy and people who are worried. The strength of Mo Yao and the Demon King of Fire was increasing day by day, but the other two Demon Kings were still in the same state. This wasn't a good thing for their status.    

　　"Rat, if we don't act now, we won't have a chance!"    

　　The White Hair Demon King and Rat King were gathered together. Their voices were cold and cold, and their eyes were shining with a fierce light.    

　　Both of them knew that if they lost the position of Demon King... Their positions would be lost, and their domains would be lost. The spiritual energy they cultivated would be greatly reduced, and they wanted to fight the Fiery Demon King again. It would be extremely difficult for Mo Yao to be on the same level as the Demon King of Fire.    

　　"Don't worry. As long as I make a move, that kid won't be able to escape from my palm!"    

　　Rat King patted his chest and said confidently.    

　　As the Rat King, he had a profound understanding of the art of concealment. Furthermore, there was a huge gap between him and Xu Feng. He didn't think that Xu Feng would be able to escape from his grasp.    

　　"Don't kill him by accident. If we kill him, we will lose all hope!"    

　　After saying that, the white-haired old man vanished into the void. Rat King glanced at the cave of the Demon King of Fire and disappeared as well.    

　　It was better to be strong than everyone else. After all, the four Demon Kings had controlled this world for thousands of years. They wouldn't allow anyone to break the balance of this world. That was why the Rat King and Xu Feng had made up their minds to obtain the martial art in Xu Feng's hands.
