"Yeah." Li Chuan nodded. While speaking, he reached out and held Tianxingba in his hand. Holding the sword now, the feeling was completely different from before. It was a feeling of blood connection, as if the sword was no longer a sword, but an extension of his arm. Moreover, his whole body also entered a strange state in an instant, as if he had become one with the surrounding heaven and earth. Although he did not move, he could sense the ubiquitous power of heaven and earth around him. At this moment, he finally understood the difference between Heavenly Sword and Taoism. Taoism uses media such as spells and spells containing the laws of heaven and earth to obtain the power of communication between heaven and earth. Its essence lies in the word "borrow", and even some overbearing techniques are controlled by force. The Heavenly Sword is different. It is a kind of integration and a kind of resonance. If you practice it to the extreme, you will be indistinguishable from heaven and earth and reach the highest state of coexistence with heaven and earth. This is the essential difference from Taoism, and the gap between the two realms is self-evident. &nb;From now on, he will no longer be restricted by the previous levels of Formation Pill, Yuanying, etc., and his cultivation level will continue to increase with his understanding of the Heavenly Sword. From this, he gained a deeper understanding of the ancient martial arts techniques, and also understood why the ancestors of each ancient martial arts sect strictly prohibited their disciples from practicing the cultivation techniques. At the initial stage of cultivation, there is not much difference, but when cultivation reaches a higher level and the inner elixir is formed, it is no longer suitable for practicing ancient martial arts. Because once you understand the Heavenly Sword, under the infusion of the spiritual energy of heaven and earth, no matter how strong the golden elixir in your body is, it will definitely break in an instant. This is almost an unbearable trauma for the cultivator, because once the inner elixir is formed, the cultivator's soul will be attached to it, and the broken inner elixir will inevitably cause the soul to suffer heavy damage. In this regard. Li Chuan is different because his soul is not here. And in the black flame of the soul in the sea of ??consciousness. It is not suitable to comprehend the Heavenly Sword even after forming the inner elixir, and it is even more impossible after the inner elixir is shattered and transformed into an infant. At that time, the Nascent Soul and the soul have become one, and except for some special exercises, it is difficult to separate the two. In this case, to comprehend the Heavenly Sword again is no different from committing suicide. The moment they comprehend the Heavenly Sword is the moment they die. Of course, it is not ruled out that some lucky people will survive in the end, but that chance is probably much lower than enlightening the Heavenly Sword. Think of these. He couldn't help but secretly sigh, if those in the ancient martial arts sect learned the news, the blow would be unbearable for many people. Although everyone knows that the possibility of enlightening the Heavenly Sword is very slim, there is still hope after all. It is the spiritual pillar that they have been insisting on to enlighten the sword. Once it is shattered, you can imagine how they will feel. "Where are we going next?" Concubine Luo Yu asked. "Originally I had to look for other clues leading to the underworld. Now that my seal has been unlocked, it is better to go back to the sect to retreat and work hard to improve the soul-eating demonic cultivation. That underworld minefield is not an ordinary place. If something goes wrong, I'm afraid he will be completely buried there." Li Chuan thought for a while and said. Then he closed the demon refining formation with a thought. After checking around, he didn't find anything strange, so he raised his hand to clean up the battlefield. The gains from this battle are not small. "Well, after visiting Senior Ziyun this time, I will start to retreat. If nothing happens, I may break through in a short time." Luo Yufei said. "So fast?" Li Chuan frowned when he heard this. Although this is something to be happy about. But he really couldn't be happy. For Concubine Luo Yu, who has a physique with nine yins and no pulses, only her cultivation has reached the out-of-body stage. Only then will she truly no longer suffer from the cold poison, and then such a physique will be of great help to her cultivation. But before you can reach the out-of-body stage, you need to pass countless levels, and among these levels, the Nascent Soul stage is undoubtedly the most dangerous. "Well, it may have something to do with the forbidden technique I used this time." Concubine Luo Yu nodded. "It's okay, I have everything." Li Chuan said. "I know." Concubine Luo Yu whispered, "Feng Yun Hui." After Li Chuan returned to the sect, he gave a brief explanation and officially started practicing in seclusion. The place of retreat is a huge and empty stone room. He set up a demon refining formation and sat cross-legged on a jade bed. After thinking for a while, he took out a jade slip, probed into his spiritual consciousness, and closed his eyes to meditate. This jade slip was the jade slip he used when he burned and copied the Silver Light Thunder Formation in Shuiyun Pavilion. He had meditated on this formation many times before and had a lot of experience. Although the silver horn was not enough to compare with other For some reasons, he couldn't completely copy the formation, but he could still arrange a simple silver light thunder formation, especially with the help of Qinglong, a powerful spiritual beast, it would be no problem. Of course, to put this into practice, some details need to be thoroughly figured out, and that is exactly what he is doing now. Half a year later, a simple silver light thunder formation was finally completed. A spell was fired, and there was a burst of rune fluctuations in the air, followed by a dazzling silver thunder light that slammed down with a "click" ten years.Time passed quickly. On this day, Li Chuan suddenly raised his head and opened his eyes, and fired a magic spell to close the silver light thunder array. He frowned slightly, sighed, and once again circulated the soul-eating demonic path for several days, and slowly stood up. This retreat lasted longer than he imagined, but it did not reach the peak of the flame infant stage as he imagined. Although there is only one step left, it has been impossible to take it. After thinking for a while, he suddenly flicked his long sleeves, and then a pale-faced Li Qing appeared on the jade bed. After releasing his spiritual consciousness to investigate, Li Chuan's face suddenly turned ugly. Her soul was more than ten times stronger than it was ten years ago, and it was like a bottomless black hole that was constantly devouring her life. If she hadn't been a cultivator and her vitality was much stronger than that of ordinary people, she would have died long ago. This situation has left him, the successor of the Soul-eating lineage, at a loss. No matter how serious the physical injuries are, he can still help them recover. Of course, the injuries to the soul are not to mention. But Li Qing's condition was neither physically injured nor soul injured, which made him feel helpless and powerless. "It seems that before going to the underworld, we need to find a way to refine a furnace of fortune-enhancing pills. Otherwise, with the speed at which Qing'er's vitality is being consumed, I'm afraid we won't be able to wait until the day we find a solution." Thinking of this, Li Chuan suddenly released His consciousness began to explore the ring. After a while, he shook his head, closed the formation, and walked out with a solemn expression. Half a quarter of an hour later, he appeared at the place where Ziyun Zhenren was refining alchemy. At this moment, Master Ziyun was refining elixirs. He hesitated slightly when he saw this, but finally stood aside quietly without speaking. "Seeing that you came in such a hurry, is there something urgent?" After a moment, Master Ziyun said after collecting his magic skills.
