However, Tan Fei's current method of condensing Qi into a gang is only the beginning. To truly reach this state, he still needs to reach the pill formation stage. Because there is no condensed golden elixir, it is impossible to activate Gang Qi. Even so, Tan Fei also received great benefits this time, which allowed him to improve his cultivation again and reach the limit of the third level of foundation building. He only needed the last bit to break through and reach the fourth level of foundation building. "Great! I never thought that my body would show signs of Qi Qi becoming a gang in advance. Isn't it possible to qualify only after reaching the seventh level of foundation building?" Tan Fei was overjoyed, and quickly started to turn on the exercises. Mobilize the true energy and re-rotate the vortex of pure and refined true energy in the body. This vortex of true energy is dozens of times smaller than before. It is incomparable in terms of momentum, but in terms of real power, it is more than ten times more powerful than before. Tan Fei is confident that if he meets Qin Leng now, he won't have to bother you at all. He can just fly his sword through the hole and kill him in one go, solving the problem without giving the old guy a chance to resist. As for the Great Elder Ning Xu, before he refined the sword energy and transformed into a form, he still had no ability to resist, but at least he could escape without being forced into such an embarrassing situation that he even wanted to release Bai Xuan to resist. "I can't believe! This golden giant city has such a use. Forcibly compressing the true energy is simply cheating! If I advance to a higher level every time, this golden giant city will release strong pressure to help me purify the true energy, saving a lot of time. "It won't take more than three to five years for me to reach the pill formation stage." Tan Fei was happy in his heart and was about to try the power of these newly generated Qi. Who knew that at this time, another change occurred, and the core that had been originally formed changed. The Dongming Pearl he had stored in his belly suddenly moved. After Tan Fei got the Eastern Pearl, he used it several times to spread out a hundred-foot thunder field, all of which had good effects. He fell in love with this middle-grade treasure even more, and simply swallowed it. This is also a common method of collecting magic weapons. Generally, magic weapons can be carried with you or stored in a treasure bag. But both methods have drawbacks. It¡¯s easy to lose them when you carry them with you. After all, you¡¯re more afraid of something unexpected than ten thousand. Especially after a long time, mistakes will inevitably happen. Although it is safer to put it in a treasure bag, it will cause some worries. At a critical moment, the treasure bag must be opened to release the magic weapon. Sometimes, in a critical moment, the skill of opening the treasure bag may determine the outcome of life or death. Therefore, many people simply put some key and commonly used magic weapons directly in the body, or swallow them in the mouth, or bury them under the skin, directly connected to the qi and blood, and can be launched with a spiritual thought. Tan Fei was also in the same situation. He swallowed the Eastern Pearl in his belly and thought he was infallible. But he didn't expect that at this time, something went wrong! Just after his true energy was completely stabilized and a new true energy vortex was formed in his dantian, suddenly a force came from the center of the vortex, reaching the East Pearl! Originally, after Tan Fei refined the East Pearl, it was connected to his true energy. At this time, it was suddenly pulled. Before he could react, when he was slightly stunned, the East Pearl had been forcibly absorbed into his Dantian. among. Immediately afterwards, a greater suction force came out of the vortex, trying to suck the Dongming Pearl in! "Master! Master! What's going on! If you are dissatisfied with me, I will correct it in the future. Why do you need to refine me!" When the weapon spirit of Dongmingzhu discovered this situation, it immediately appeared, conveyed its spiritual thoughts, and begged hard. . But this was not Tan Fei¡¯s original intention at all. Hearing the spirit¡¯s begging, he had nothing to do. "Wait a minute! Let me see what's going on?" Tan Fei responded quickly, while activating his spiritual thoughts to try to cut off the suction force. He has finally obtained a medium-grade spiritual weapon now, and he doesn¡¯t want to lose it in vain. Once the Dongming Pearl is sucked away, the outcome is unpredictable. However, at this moment, a trace of spiritual thought suddenly came to Tan Fei's mind. It was an eternal and desolate voice: "Little baby! Don't resist, I'm helping you bring the thunder into your body. The Nine Heavens and Ten Earths Ten Thousand Thunder Transformation Technique that you practice must go through this process, otherwise it will not succeed! This thing The pearl is barely usable. You integrate it into your Dantian and use it as the core of the Nine Heavens and Ten Earths Ten Thousand Thunder Transformation Technique. This is not only good for you, but also the creation of this orb. " "Who are you!" Fei was immediately shocked. When he heard that voice, the hairs all over his body stood up, and he could not suppress an inexplicable fear in his heart. In that trace of spiritual thought just now, he felt an extremely powerfulThe breath seems to have traveled through eternity, or even further back. It already existed in chaos before the beginning of the world. That is a natural fear. Not to mention Tan Fei, who has just reached the foundation building stage, and is probably an immortal who has joined forces to overcome tribulations and ascend to the immortal world. When encountering this trace of divine thought, he will have an uncontrollable fear. However, that trace of spiritual thought was just a shock, and when Tan Fei asked again, there was no response. If the impression just now hadn't been too deep, he might even have doubted whether it was his auditory hallucination: "Who is the owner of this spiritual thought? Did it originate from this giant golden city? But why did he want to help me?" Do you have any ill intentions towards me? " In an instant, countless questions surged through Tan Fei's heart, but unfortunately that divine thought never appeared again, and it was even less able to answer his doubts. "What should I do now? He said that he asked me to integrate the Dongming Pearl into my Dantian, otherwise I won't be able to refine the true secret of Nine Heavens and Ten Earths Ten Thousand Thunder Transforming Energy! I don't know if it's true or not, should I believe it?" Tan Fei thought to himself, left and right I thought about it, weighed the pros and cons, and finally made up my mind! "That's it! In this case, I will believe it once! It is a middle-grade treasure anyway." Tan Fei was heartbroken and did not hesitate anymore: "Last time we were in Yue Lake, the magic weapon at the bottom of the lake could be The Taoist weapon was also swallowed up by the golden city!" Thinking of this, Tan Fei's heart calmed down, and his mind suddenly moved, and he communicated with the weapon spirit: "Dongming boy, don't worry now! To refine you, I want you to become the core of the Nine Heavens and Ten Earths Ten Thousand Thunder Transformation Strength True Technique, which is good for both you and me. " "What! The Nine Heavens and Ten Earth Thousand Thunder Transformation Strength True Technique! Master, you are practicing this thunder method!" Upon hearing Tan Fei's report on the true method of transforming the power of thunder into nine heavens and ten earths, Dongming boy suddenly became energetic. He had heard of it before and was very familiar with it. "Yes, you also know this technique?" Tan Fei asked. "How come you don't know! This is the true secret of transforming tens of thousands of thunders into energy. It is known as the best thunder method in the world. Back then, Old Man Tianji relied on this thunder method to travel across the world, creating a great reputation, and finally ranked as one of the seventy-two immortals of Pangu. , Thunder magic weapon in the world, everyone is born with a weapon spirit, who doesn¡¯t know it?¡± When Dongming said this, he also became excited. "I never imagined! One day, I will be able to meet someone who practices this thunder method, and I will be lucky enough to become the core magic weapon of this thunder method! This is my destiny, master, thank you!" As he spoke, that heart Dong Mingzhu no longer resisted the suction, turned into a ray of green light, and suddenly flashed directly into the vortex of true energy. In an instant, Tan Fei was shaken again, and then bursts of rumbling thunder erupted in his body, and arcs of electricity flashed out with crackling sounds. Tan Fei was slightly startled. He heard from the Dongming boy's words that it seemed that the reputation of this Nine Heavens and Ten Earths Ten Thousand Thunder Transformation Technique was widely spread among the weapons and spirits of thunder magic weapons. "Could it be that the weapon spirits of these magic weapons also have their social circles and can communicate with each other?" Tan Fei couldn't help but be a little surprised. He had never known that there was such a connection between the magic weapons that generated weapon spirits. This seems to be some kind of network. Even if the distance is far away, with special means, we can sense each other and convey information to each other. Of course, this was Tan Fei's guess. Because of the emergency situation, he had no time to verify it. The Eastern Pearl had already been thrown into the vortex of his true energy. At the next moment, thunder and lightning broke out
