Suddenly clear and bright

  Fang Yu's mental strength almost doubled, reaching nearly the level of a spiritual system mage.

  Fang Yun refined the Extreme Spirit Cold Pearl into a magical treasure, and the main change of the Extreme Spirit Cold Pearl was to form a cycle between the immortal energy and the Extreme Spirit Cold Energy, which would not become an empty shell due to Fang Yu's absorption.

  At the same time, Fang Yu's spiritual power will grow infinitely in unintentional absorption, and this growth will be unnoticeable.

  Even Fang Yun couldn't meet Fang Yu's future spiritual power. Perhaps he would form his own divine sense like a cultivator, or take another path.

  Of course, on the premise that Fang Yu needs to have a lifespan like that of an Infinite Cultivator, giving her sufficient time.

  Moreover, there must be levels that she cannot encounter, after all, no matter what kind of cultivation it is, it belongs to going against the heavens, and there are many invisible levels waiting for her.

  The next day, Fang Yu slowly opened his eyes, and the first thing he saw was his detestable younger brother.

  Fang Yu immediately unleashed her fury, bravely pinning Fang Yun to the ground, pressing him against the headboard: "You scoundrel, compensate me for my blue pearl! You compensate me for my blue pearl!"

  Fang Yun was grinning from ear to ear, holding a blue gemstone the size of a fist in both hands: "You owe me."

  As soon as Fang Yu saw the Extreme Spirit Pearl, her eyes widened immediately. The spiritual connection produced by the Extreme Spirit Pearl made her feel infinitely close to it, a feeling that was hard to describe, as if it were a part of her own body.

  Fang Yu's soul was drawn in by the blue glow, his eyes were deeply attracted to it and couldn't help himself, his hands slowly picked up the Extreme Spirit Cold Pearl.

  This feeling can only be felt by Fang Yu. If it were someone else, they would think it's beautiful at most, but wouldn't feel what Fang Yu is feeling right now.

  "Satisfied with...?" Fang Yun's face was filled with a smile as he gazed at Fang Yu.

  Fang Yu glared at Fang Yun fiercely, then withdrew his gaze and placed it on the Extreme Spirit Pearl: "I'll let you off this time!"

  "Let me go if you're satisfied. How long do you want to keep pressing me?" Fang Yun rolled her eyes at Fang Yu, who was clearly written all over his face but still pretended to be calm and collected.

  The next day, Ye Lao came to find Fang Yun again. He was no longer as anxious as he had been in the past few days, because he discovered that the changes in his internal energy not only did not bring him harm, but instead brought him endless benefits.

  If there's one real drawback, it's that in the past I was plagued by old ailments and had trouble falling asleep, whereas now I'm bursting with energy and have trouble sleeping.

  This made Ye Lao laugh and cry at the same time. It seemed that heaven was determined not to let him sleep, but the other party's gratitude and respect for Yun only grew deeper.

  "Old Ye, I haven't figured it out yet, why have you come again today?" Fang Yun led Old Ye into the room, looking at him helplessly.

  "Yun, I've come to tell you that you don't have to worry too much about my body. The biggest problem has already been solved, and the remaining minor issue isn't worth worrying about. Moreover, this is not a bad thing for me either." Ye Lao said with concern.

  "Old Ye, apart from the increase in your aura's sustaining power, what other changes have occurred to your aura?" Fang Yun did not give up, studying Old Ye's changes, not for Old Ye's sake, but for his own.

  Fang Yun's medical skills didn't come out of thin air, it was precisely because of countless sleepless nights spent solving inexplicable mysteries that Fang Yun could unravel them one by one, allowing him to achieve what others couldn't.

  If an inexplicable mystery is encountered and left unsolved, Fang Yun's medical skills will forever stagnate.

  There are many unheard-of and unseen cases in this world, Fang Yun is not satisfied with the status quo, only with a desire for knowledge can he have enough motivation.

  Ye Lao looked into Fang Yun's eyes and understood that he wouldn't give up like this. He seemed to see the generations of Fang family heads, all of whom had such a gaze - firm and resolute.

  Ye Lao sank into thought for a moment, furrowing his brow as he looked at Fang Yun: "I don't know either, does this count as change..."

  Ye Lao paused for a moment, then continued: "Nowadays, in my mind, I will unconsciously recall the mnemonic you gave me, Cloud. Every time I recall it, the aura will circulate along with it. Sometimes when I haven't recalled it, but when I operate the aura, it will also automatically circulate in the way of the mnemonic."

  "Are you saying that when you use internal energy, the incantation will run automatically?" Fang Yun asked with wide eyes.

  "Yes... I thought that was the characteristic of Yun Shao's oral trick... So I didn't say anything that day..." Ye Lao scratched his head awkwardly, every time he was with Fang Yun, he felt extremely relaxed.

  In his eyes, there was no distinction between master and servant. Fang Yun seemed more like his grandson, and Fang Yun's intelligence always left him speechless.

  "The formula I gave you doesn't have such magical effects." Fang Yun shook his head.

  There are indeed automatic cultivation methods in this world, but such methods may not be the best, because automation implies that some things need to be sacrificed, such as the speed of cultivation, which may not be as effective as active cultivation.

  However, he did not expect that his own chant for refining the Xian Qi would automatically run on Ye Lao's body.

  If that's the case, it can only be explained as instinct, because Fang Yun's oral formula for Ye Lao has no automatic effect, and the oral formula may vary from person to person, achieving different effects, but it won't change due to differences in energy.

  It's possible that Ye Lao was cured of his old illness by Fang Yun, and the effect of the mantra was extraordinary, causing him to subconsciously remember the mantra in his heart. When he circulated his internal energy, he instinctively recited the mantra.

  "Old Ye, use your internal energy now." Fang Yun said seriously.

  Ye Lao nodded slightly, stretched out his palm, and a ball of black flames suddenly burst out from the center of his hand, grasped in Ye Lao's hand, emitting a humming noise and scorching heat.

  Now at night, Lao Shi is displaying his inner energy, and there will be no more pain, but instead, his body feels extremely comfortable.

  A gentle breeze blew in, and the door creaked with a groan. Fang Yun was taken aback - where did this wind come from inside the house?

  "No, this wind carries the spiritual energy of heaven and earth!" Fang Yun's divine sense immediately detected that something was off. This wind carried a thick spiritual energy, clearly having been attracted here.

  The spiritual energy of heaven and earth exists in the air, all things in the world have the spiritual energy of heaven and earth, but there are more or less, some special places or landforms can gather more concentrated spiritual energy.

  For example, Fang Yun's small courtyard has a gathering spirit array, so the spiritual energy is more concentrated. Other places are much thinner, normally the ratio does not exceed 100:1.

  So it won't be for no reason that a gust of spiritual wind has blown by, and it must have been attracted by Ye Lao.

  Fang Yun wrapped his divine sense around the black flames, feeling the changes in the black flames. The black flames did not waver in the wind, but instead became even more vigorous and intense, like oil on water.

  "It's the aura that's attracting the spiritual energy of heaven and earth!" A flash of light flickered in Fang Yun's eyes.

  Fang Yun immediately placed his hand on Ye Lao's wrist, channeling the immortal energy into Ye Lao's body. He observed Ye Lao's physique and found that the old man was indeed automatically circulating the incantation.

  Fang Yun smiled and basically understood the general reason. He had thought too much before, so he fell into a dead end.

  Actually, the old man's aura had not undergone any changes, but what changed was the way he operated. On one hand, he released his aura according to the Black Sky Demon Flame's aura method, while on the other hand, he instinctively ran the Xian Qi Lian Hua Kou Jue.

  This mantra itself has the effect of refining and transforming immortal energy, but in Ye Lao's body, there is no more immortal energy to refine.

  So Ye Lao's body began to absorb the spiritual energy of heaven and earth, after all, immortal energy is refined from spiritual energy. Immortal energy and spiritual energy are like the relationship between pure oxygen and air, immortal energy is a more pure energy, while spiritual energy is mixed with impure energy.

  At the same time as Ye Lao released his aura, his body was also inefficiently refining spiritual energy, which is why Ye Lao's aura had a greatly increased endurance.

  Although this state is good, only Ye Lao can achieve it and cannot be replicated by a second person, because this is due to instinct. Ye Lao has superstitious reverence for the oral formula, but others may not necessarily be able to achieve one mind with two uses.

  "Old Ye..." Fang Yun smiled slyly: "Remember our agreement?"
