When Tan Fei discovered this situation, he was slightly stunned at first, and then he was overjoyed: "The true energy is surging, remove the rot and retain the essence!" At this moment, every time Tan Fei's true energy reaches the limit, it is suppressed by the power of the golden city, and then It's like being refined once. This process is like steelmaking. A piece of cast iron is tempered many times to remove impurities, and finally it can be made into steel. The same goes for Tan Fei's true energy. As it expands and suppresses again and again, impurities are gradually eliminated and it becomes more pure. Originally, his Qi was much purer than that of people with the same level of cultivation, but now, it has become even worse. Tan Fei had an idea and thought: "I'm not in a hurry to break through. I might as well take this opportunity to temper my true energy to the limit, and then break through to the third level of foundation building. This will have a great impact on my future cultivation." Benefits." When Tan Fei thought of this, he immediately made up his mind and did not rush to activate his true energy. Instead, he calmed down and allowed his true energy to surge. At the same time, he also made up his mind to wait until this breakthrough passed and reached the third level of foundation building, and then immediately return to Feiyun Gate and completely eliminate the hidden danger of Qin Leng. "Qin Leng, you old dog, wait for me!" Tan Fei cursed in his heart, with murderous intent in his eyes! Qin Leng was bribed by Ning Wuque and others, and tried to kill him many times, and had formed a mortal enemy with Tan Fei. If it weren't for his strong strength and some luck, Tan Fei would have died silently in this corner of the deep mountains and forests. Tan Fei is not the kind of pedantic scholar who repays evil with kindness. He wants to repay tooth for tooth and eye for eye. Since Qin Leng wants to kill him, he will kill him back. He will not be patient or tortuous, otherwise his thoughts will be blocked and his own cultivation will be affected. It will have a huge impact. The way of cultivation is not to seek perfection, nor to endure hardships, not to mention that a gentleman is never too late to take revenge after ten years. Tan Fei sneered at these. Only by having clear thoughts can one understand the true meaning and reach a higher level. Otherwise, he can only be trapped. In a corner, I restrain myself in my heart, unable to reach a higher state. This is Tan Fei¡¯s character and his understanding of cultivation. However, this does not mean that he is reckless and rushes and fights fiercely. That is a reckless person who seeks death rather than having clear ideas. Moreover, Qin Leng is a veteran elder of Feiyun Sect and has now reached the third level of foundation building. If Tan Fei wants to kill him, he must prepare carefully. He must first break through the third level of foundation building before he can compete with Qin Leng's inferiority. If he wants to be sure of victory, then Four levels of foundation building are required. Strength! This is the foundation of everything. Without strength, nothing can be said! Tan Fei thought for a moment, then took some time off, and once again put all his energy into his body, looking inside his Dantian, not daring to make any mistakes, until he went back and forth hundreds of times, and after several hours, his true energy reached a limit. His current level could no longer be improved, so he stopped. "Third level of foundation building! Give me a breakthrough!" Tan Fei suddenly opened his eyes, and light shot out from his eyes. The sound echoed throughout the cave, causing the gravel on the top of the cave to fall downwards. At the same time, a powerful flow of air burst out from his body. The true energy was released and condensed into Gang Li, forming countless white awns several inches long. The gravel falling from the roof of the cave reached the Gang Qi, and there was an immediate snap. , directly collapsed into powder. Tan Fei's momentum skyrocketed, and the true energy in his body surged, like water bursting out of a dam, out of control. Twice! double! three times! In an instant, Tan Fei's true energy surged seven or eight times, and became purer. As it rotated along the meridians, it became thicker and shinier, and already had some metallic luster. Generally speaking, from the second level to the third level of foundation building, the true energy will increase three times. Only those with extraordinary talents can reach an extraordinary level of five to six times, and there are very few who can increase it seven or eight times in one breath. , can be said to be uniquely blessed and an unparalleled genius. ¡° Then, after about half a stick of incense, Tan Fei¡¯s Gang Qi subsided, leaving only the true Qi that swelled up, making his clothes swell, as if his whole body had gained weight. Tan Fei¡¯s mind is focused on nothing else, and the calm energy of the underworld guides the true energy to circulate in the body. This is also the most important step after a breakthrough, to guide the Qi to calm down, allow the body to adapt, and gradually become familiar with it. Otherwise, the true energy will surge, become more powerful and faster, and you will not be able to adapt to it for a while. When stimulating the true energy, if you are not careful, you may use too much force and injure the meridians and Dantian. Therefore, you must be careful at this time and remember not to act too hastily. Especially Tan Fei, when he reached the second level of foundation building last time, he was in a hurry. This time, he had to be more careful and not leave any hidden dangers. Tan Fei had enough patience, calmed down, and was not in a hurry. He slowly guided his true energy until he finally returned to Dantian for ninety-nine and eighty-one weeks. A huge vortex formed under the golden city and became quiet. , turned slightly, and then he breathed a sigh of relief.? At this time, a full day and night had passed since he entered the cave. "Third level of foundation building! This feeling again, breakthrough in cultivation, reborn!" Tan Fei stood up and suddenly felt refreshed, his whole body was light and airy, that feeling was extremely comfortable. Last time, when he reached the second level of foundation building, he had this feeling. Because of his breakthrough in cultivation, he learned about the old and adopted the new, his true energy was purified, and the impurities were eliminated, and his whole body was adjusted to the best condition. "Okay! The third level of foundation building! Now as long as I take the Lingyun Pill and use the power of the medicine to improve it again, I can reach the fourth level of the foundation building stage, and may even reach the fifth level, and steadily suppress Qin Leng's old dog , kill him and eradicate him! Chen Wei is also a scourge. This time he and Ning Wuque are colluding with each other, so they must be eliminated together. " Tan Fei then thought of Qin Leng and Chen Wei. There was a slight sneer on his lips, and the killing intent in his eyes was even colder. However, just when he was about to take out the Lingyun Pill, a powerful force suddenly blew from the back of his head, with a faint fragrance and a very good smell. "Who!" Tan Fei was stunned for a moment, and then a warning sign appeared in his heart. He turned around and looked around, but there was nothing. "Huh? Is it my imagination?" Tan Fei frowned, and when he turned around, he suddenly found a pale little girl floating in front of him. "Ghost!" Tan Fei was shocked, and all the hairs on his body stood up. Although he has now entered the ranks of cultivation and should not be afraid of ghosts, at this moment, a gloomy aura enveloped him, making him involuntarily feel fear. In fact, what people are afraid of is not ghosts, but death and the unknown. "Hehehe! Have you finished practicing? Come and play with me!" When the little girl saw Tan Fei looking over, she immediately showed a big smile and said to Tan Fei crisply. It can be said that this little girl is very cute. Apart from her pale face, there is nothing scary about her. Her smile should give people a feeling of spring breeze. However, when Tan Fei saw this 'cute' smiling face, he couldn't relax no matter what. "It's certain that this little girl is a fierce ghost!" Tan Fei took a step back, his expression becoming increasingly wary: "But ordinary ghosts and ghosts can't get close to me at all. As long as they get a little closer, their true energy will be stimulated and their souls will be strangled. Why is this little girl so weird? I can't feel her breath. If she hadn't blown it behind me on purpose and appeared on her own initiative, I wouldn't have even known there was her in this hole." "Aren't you willing to play with me too?" The little girl seemed very disappointed when Tan Fei didn't speak, and said pitifully. Tan Fei couldn't help but be stunned. It seemed that he was affected by her, and his mood immediately dropped. Even the excitement of having just reached the third level of foundation building disappeared completely, as if he had done something unforgivable and bad. "What's going on? What's going on? Could it be that this little girl can affect my mood? This is incredible?" Tan Fei quickly reacted, feeling even more shocked and doubtful about what this little girl was. In her background, she was by no means an ordinary evil spirit. "Little sister, what's your name?" Tan Fei asked tentatively. But the little girl fell into her own world and kept repeating: "You are all bad people and you don't want to play with me! You are all bad and you should all die!" As he spoke, The little girl's expression became extremely ferocious, her two pupils turned red, blood stains flowed from the corners of her eyes, her face became paler, and she looked even more eerie, especially in such a dark and cold cave.
