A month passed in a hurry, Ling Fan practiced gathering aura groups very carefully every day except for eating and sleeping, and Ling Fan became more and more proficient in controlling the effective sorting and combination of aura, and the speed of gathering aura masses has improved a lot, and the shape has begun to approach a sphere.

On this day, as usual, Ling Fan went out after breakfast to find Gu Yang, or that tree in that place. When he arrived at the place, Gu Yang was not there, so Ling Fan sat under the tree and gathered the spiritual qi mass and continued to practice.

The aura group slowly changed shape, and it was still a little, it was almost a little, most of the aura was combined with each other, but it was just a little bit that it could not be perfectly combined. Ling Fan had practiced many times but had never been able to put them together, they were like a few naughty children, no matter how Ling Fan put them together, as long as Ling Fan no longer controlled them, they would scatter and return to their original positions.

Ling Fan began to look a little impatient, wanting to forcibly rub them together, but at this moment a familiar voice sounded, "Relax, don't forcibly control them, put those more active auras in the center of the aura, and let those auras that are stably combined surround them." ”

Hearing this, Ling Fan's heart slowly calmed down, and he began to try to gather that bit of unstable aura in the center of the aura mass, and then slowly wrapped them with other aura.

Ling Fan carefully controlled, little by little all the aura was sorted, the aura mass slowly began to shine from the center, the entire aura vibrated slightly, and when the light emitted from the center wrapped the entire aura mass, Ling Fan felt that the entire aura mass was no longer chaotic and complex as before, but was integrated.

Did it succeed? Ling Fan opened his eyes and looked at the mass of aura in his hand, which seemed to be the same as the aura mass gathered by Gu Yang in terms of shape. Great, before Ling Fan could laugh, bang, the entire aura mass scattered in all directions.

"Eh, Grandpa Gu, this ......" Ling Fan looked at Gu Yang in front of him at a loss, he originally thought that he had succeeded, but it only lasted for a moment.

"Boy, don't be discouraged, in general, your progress has been very fast, you have successfully gathered the aura mass just now, but it is not stable enough, and when you practice to make the aura mass stable enough, you can compress and temper it. Gu Yang said to Ling Fan with a smile.

"Grandpa Gu, what's going on with those more active aura?" Ling Fan asked.

"The purer the aura, the more active it is, so that's why you put them in the center, and when you start to compress and temper them, the purest aura is left in the end. Gu Yang explained.

Pure aura, Ling Fan can indeed feel that the speed of the flow of aura around him is indeed different with his super perception of aura, some seem to be walking, and some are like running non-stop, although Ling Fan discovered this very early, but it wasn't until Gu Yang told him that Ling Fan didn't know why.

"Grandpa Gu, in that case, why do I need to compress and refine it? Can't I just find the pure aura and absorb it?" Ling Fan asked.

"Don't think about it simply, you kid, when cultivators start cultivating, they absorb the most stable spiritual energy, and then compress and refine it in their bodies. That's because the purer the aura, the more powerful it is, not to mention your physique, even if a normal cultivator directly absorbs the pure aura, he will also run away because the body can't bear the aura, and the injury is a trivial matter, and if you are not careful, you will die. Regarding the question raised by Ling Fan, Gu Yang said solemnly.

"Even a strong cultivator must first compress and temper the pure aura when absorbing it, so that the aura does not run wild in the body. Gu Yang continued.

Ling Fan thought that it was fortunate that he asked first, otherwise if he really went directly to absorb the pure aura, even if he really succeeded, with his body, which was extremely painful to absorb normal aura, he was afraid that it would not be much better to not die.

"Grandpa Gu, does a strong cultivator also want to compress and refine the aura outside the body and then cultivate?" Ling Fan asked curiously.

"You kid, don't you know anything about cultivation?" Gu Yang said with a bad face.

"Uh, indeed," Ling Fan replied.

Although Ling Fan also had some books introducing cultivation methods when he was in Tianyuan Mountain Villa before, at that time, Ling Fan thought that he couldn't cultivate, so he didn't care about this aspect, but put all his energy into normal study, so although Ling Fan was not very old, he knew the words very well, and he could read almost all kinds of books. Until Gu Yang asked like this, Ling Fan was also a little embarrassed.

"Okay, kid, then I'll teach you a lesson today, cultivators can be roughly divided into several stages, five levels: entry, imperial spirit, suppression spirit, spirit descent, and divine descent. The entry stage is divided into four levels: perception, Naling, quenching, and forging the body, and the forging body can accommodate the aura in the body when it reaches a certain level, and then the spiritual sea is formed in the body, and then it really enters the stage of the spirit, and the stage of the spirit is divided into the spirit master, the spirit master, and the spirit control stage, and the spirit control stage is the spirit control stage, which is also divided into the spirit control person, the spirit control envoy, and the spirit control master. Then there is the spiritual descending stage, the spiritual descending realm is only divided into two levels: the spiritual descending envoy and the spiritual descending master, breaking through the spiritual descending stage, that is, the divine descending stage, there is only one level, the divine descending master, that is the strongest of the really strong. So, boy, check for yourself what level you are at. Gu Yang said a lot in one breath, and Ling Fan quickly remembered it in his mind.

In this way, Ling Fan felt that he was at the level of Na Ling at best, if according to Ling Fan's current situation, he could only be regarded as perception, after all, he could not absorb spiritual energy now. In fact, what Ling Fan didn't know was that since his body had been inexplicably healed since he had been injured before, Ling Fan's body had become much stronger than before. And when Ling Fan was practicing the Imperial Object, he was eroded by his own blood and changed his appearance, which made Ling Fan's body much stronger than other cultivators, but Ling Fan had always been in a stable state, that is, he had not fought with anyone or been injured, so he had no way of knowing.

While Ling Fan was thinking about it, "Okay, kid, gather the aura mass again and try to maintain it as stable as possible." Gu Yang suddenly interrupted Ling Fan's thoughts.

"Oh. Ling Fan obediently obeyed, raised his hand and closed his eyes to concentrate on gathering the spiritual energy, and soon the spiritual energy mass slowly turned into a round ball shape, this time it was a little better than before, after all, he had experience. Ling Fan prioritized those active aura. After the aura mass was gathered, Ling Fan tried his best to control it not to collapse.

"Very good, just keep it like this, first of all, to maintain the stability of the aura ball, and then start from the outer layer of the active aura in the center of the package, try to compress it slowly, just like kneading the dough, not too hard but try little by little. Gu Yang taught Ling Fan on the side, and deliberately said that it was like kneading dough, making Ling Fan simple and easy to understand.

Ling Fan listened to the method that Gu Yang had taught him, and began to try to compress it, and that layer of aura began to slowly shrink, wrapping the active aura in the center of the aura mass even more tightly. Just as this layer of aura was contracting, Ling Fan saw that something was squeezed out of that layer of aura, and then absorbed by the outer layer of aura. At this time, the aura mass as a whole also shrank slightly, and the whole aura mass spread out again.

Whew, Ling Fan let out a breath and looked at Gu Yang and shook his head helplessly. Gu Yang seemed to be very satisfied with Ling Fan's performance, and nodded with a smile. "Yes, you remember these tips, first of all, you must maintain the stability of the aura mass, no matter what method you use, as long as you can make the aura group stable enough, and after you are proficient in practice, the aura mass is stable enough, and then you start to practice compression and tempering, and at this time you have to make the aura mass more stable from the inside to the outside layer than the layer, so that when you start compressing from the inside, the outer layer of aura can withstand without collapsing the aura mass. Gu Yang taught carefully, explaining to Ling Fan word by word.

Ling Fan felt that Gu Yang was extremely serious and serious today, he had been with Gu Yang for a month, he had never seen Gu Yang so careful, usually Gu Yang was always giggling, and he didn't have the demeanor of a teacher at all, and today it was like a different person.

Ling Fan listened carefully, but he couldn't help but ask, "Grandpa Gu, what you said seems to be inconsistent, right? You asked me to keep the aura mass stable no matter what method I used, and you made me more stable from the inside to the outside, this ......"

Gu Yang glared at Ling Fan, "If you can't maintain the stability of the aura group, then everything behind it will be in vain." Gu Yang blew his beard and said, Damn, Ling Fan actually dared to refute him.

Ling Fan was still thinking about why he wanted to start compressing from the inside of the aura group one by one, generally it should be compressed from the outside to the inside, and the inner layer was more stable, Gu Yang was completely the opposite method of others, but seeing that Gu Yang suddenly became serious, Ling Fan didn't dare to speak again.

"Grandpa Gu, you seem to be a little different from usual today. Ling Fan asked cautiously.

Gu Yang squinted his eyes and looked at Ling Fan, "That's because today is the last time we will meet, otherwise I wouldn't have taught you the method of compression and refining when you gathered the aura mass was still unstable, you will only have to practice hard by yourself in the future, and whether we can meet again depends on fate." Gu Yang said meaningfully, and there was a trace of reluctance in his eyes.

"Grandpa Gu, are you leaving?" Ling Fan was taken aback, for him, he had already regarded Gu Yang as a relative and a teacher, and tears began to shake in his eyes unconsciously.

"It's time to go, if I hadn't met you, I wouldn't have stayed here for so long. Gu Yang said kindly.

"You take this thing, and when you have completely mastered the method of gathering spiritual energy and refining spiritual energy and really embarked on the path of cultivation, you will take it to the Sunset Academy in Sunset City and teach it to the people there. As he spoke, Gu Yang took out a letter from his arms and handed it to Ling Fan.

Ling Fan took it and looked at the letter that read "Gu Yang's own handwriting".

After Gu Yang handed the letter to Ling Fan, he waved his hand at Ling Fan and left into the distance.

Ling Fan looked at Gu Yang's back, biting his lip, his eyes wet. Don't worry, Grandpa Gu, I will definitely work harder, thank you for your careful teaching.

The silent promise was Ling Fan's response to Gu Yang, and it was also the driving force for him to move forward.
