Wealth does not show its face in daylight

  Ye Lao is a very good research subject, and Fang Yun can freely conduct various investigations on Ye Lao's body.

  Moreover, Ye Lao's internal energy is basically inexhaustible, at least when researching, Ye Lao will not get tired.

  Fang Yun also compared the Xian Qi, magic and Dou Qi. If only comparing energy levels, Xian Qi should be a higher level of energy, magic is more inclined towards the soul, while Dou Qi is more inclined towards the physical body.

  At the same time, Fang Yun also came to understand that when Dou Qi and magic power reached the fifth stage, they would condense into their own Dou Xin, while magic was Mo Hun.

  Whether it's a magic soul or a fighting heart, they all have uniqueness, just like human fingerprints.

  Different kung fu methods, different people, personalities, environments, cultivation methods, and breakthrough methods will all result in different devil hearts and demon souls.

  Fang Yun had never studied Mo Hun, but he had studied Ye Lao's Dou Xin. Ye Lao's Dou Xin was a black dragon.

  Although it is only a form, it is an extension of the fighting spirit. Although it has no consciousness, it possesses the instinct to fight. After advancing to the fifth stage, under the influence of one's own state of mind, the fighting heart will also manifest different emotions: frenzy, anger, excitement, or fear.

  After the fifth stage, each advancement will also bring about different growth in the fighting heart. If understood as Fang Yun does, this growth is similar to evolution and has even more spiritual connotations.

  In fact, the Yuán Yīng of a cultivator is very similar to the Dòu Xīn, but the reason is that it cannot engage in combat. If the Yuán Yīng is destroyed, the cultivator will be annihilated, and it can be said that the Yuán Yīng is the cultivator's alter ego.

  The Douxin is formed by the condensation of Douqi, although it has a shape, it does not have consciousness. Therefore, even if it is destroyed, another identical Douxin will quickly condense out, but its master will also suffer varying degrees of impact and consumption.

  It seems that the Infantile Heart is more practical, but in fact, the improvement brought by Yuanying is immeasurable. If the difference between the fifth and fourth stages is like heaven and earth, then the difference between a Yuanying-stage cultivator and a pre-Yuanying-stage cultivator is like the difference between humans and gods.

  The cultivator in the prenatal period, his methods can already be described as "penetrating heaven and earth", summoning wind and rain, and the strength of his physical body has also reached an indestructible degree, with a lifespan that is several times longer.

  Fang Yun's research on Ye Lao lasted for over ten years, and the results he obtained allowed him to gain a comprehensive understanding of Dou Qi.

  Ten years ago, Ye Lao took the initiative to ask Fang Hao to become Fang Yun's follower and protect Fang Yun at the same time.

  In fact, this was also Fang Yun actively letting Ye Lao follow him, which made it more convenient for him to conduct research.

  Thirty miles outside the city of Yan, there is a vast expanse of stone forest, with stone pillars of varying heights and shapes, covering an area of over 100 square kilometers, a truly magnificent sight.

  This is a natural wonder formed over millions of years. The residents of Yanjing call it the "Heap of Chaotic Rocks".

  Because of the frequent rockfall when piling up stones, there are rarely people coming here, but at this moment, in the pile of rocks, there are two figures.

  A young man sat leaning against a stone pillar, avoiding the scorching sunlight, holding in his hand a huge bright red apple, and took a bite.

  Not far away, Ye Lao lightly swung out a palm, the palm wind was strong and powerful, while also carrying a scorching black wind, towards the giant stone in front of him.

  A giant stone of five zhang in size shattered loudly, and the broken stones flew everywhere. A fist-sized piece of rock shot towards Fang Yun without warning.

  Ye Lao Da was shocked and his mind went blank for a moment. He let out a low shout and pushed both palms upwards towards the top of Fang Yun's head.

  A black light flashed by, about a dozen or so feet long, and it was a black dragon. The black dragon swept over the broken stone, and the broken stone seemed to melt away, disappearing instantly into thin air.

  The black dragon did not stop, continuing to charge towards Fang Yun's stone pillar on his head, only to hear the rumbling sound, spreading throughout the entire Stone Forest.

  Fang Yun remained calm and unaffected, as if nothing had happened. The stone pillar behind him, which was 30-40 meters high, was directly struck by the black dragon and snapped in half at the waist.

  "Come on, old man, it's just a piece of broken stone, don't be so shocked." Fang Yun said with a smile, biting into an apple.

  The old man laughed awkwardly, feeling that he had gone too far. Although he believed the broken stone wouldn't hurt Fang Yun, subconsciously, he still treated Fang Yun like a child.

  In Old Ye's eyes, and even in the Fang family, everyone treated Fang Yun as a child.

  Of course, Fang Yun was not yet an adult in terms of age. At the age of 14, his face still had a childish appearance, and his temperament was more like that of a mischievous child who didn't understand things.

  "Old Ye, your aura seems to have increased significantly this year." Fang Yun asked.

  Ye Lao nodded and said: "Indeed, in these ten years, my Dou Qi has reached the peak of Seventh Stage First Class. I believe that within half a year, I can attempt to break through."

  "It won't take half a year," said Fang Yun confidently.

  "Yunshao, what idea do you have now?"

  "These two days I'll prepare, and when the time comes, you come to my small courtyard." Fang Yun said: "I also want to study and see what difficulties there are in breaking through the bottleneck of Dou Qi."

  Nowadays, Ye Lao trusted Fang Yun's words unconditionally. As long as Fang Yun said it could be done, it would definitely be done.

  Although Fang Yun spent the past decade studying his Dou Qi, his own Dou Qi was able to grow so remarkably, largely thanks to Fang Yun's help.

  Fang Yun was relatively familiar with Ye Lao's aura, but since he was studying someone else, Fang Yun couldn't fully understand the changes in Ye Lao's aura.

  Some things can be deduced through precise reasoning and yield results, while others cannot be deduced to produce results.

  "Tuī yǎn" is a unique term in the Xiūzhēn realm. Due to their extraordinary divine thoughts, cultivators can be said to be like high-speed supercomputers, and through their own calculations, they can deduce some theories.

  The stronger the divine thought, the more complex the outcome can be. With the current divine thought that Fang Yun can manipulate, it is not enough to deduce the result of Ye Lao's current Dou Qi growth, so he can only conduct research and analysis through on-the-spot observation and exploration of Xian Qi.

  Back in the city, Fang Yun let Ye Lao return home first, while he found a store that specialized in selling energy crystals.

  The shopkeeper immediately came forward and first looked at Fang Yun with a somewhat cold tone, asking: "Young master, what do you want?"

  The shopkeeper didn't recognize Fang Yun. Looking at Fang Yun, who appeared to be only fourteen or fifteen years old and wasn't wearing particularly luxurious clothes, he thought that Fang Yun wasn't there to buy energy crystals.

  After all, most people who come to buy energy crystals are not young men like Fang Yun.

  "Energy crystal." Fang Yun ignored the shopkeeper's disdainful gaze, for in this world there were many people like him, and Fang Yun didn't bother to pay attention.

  "This young master, the energy crystals in our Crystal Workshop are all of high quality, not those low-quality ones that cost only a few taels of silver." The shopkeeper hesitated for a moment before continuing to speak.

  "Give me thirty intermediate quality and five high-quality energy crystals." Fang Yun continued.

  "Thirty mid-grade energy crystals, three thousand taels; five high-grade energy crystals, five thousand taels. A total of eight thousand taels." The shopkeeper apparently still hadn't realized that the young man in front of him was indeed a 'big customer', and he still had an arrogant expression on his face.

  He still stubbornly believed that Fang Yun's age didn't know the value of energy crystals, and of course, most boys of Fang Yun's age couldn't afford to spend so much money.

  Fang Yun patted his chest, pulled out a stack of silver bills, counted eight and handed them to the shopkeeper.

  In recent years, Fang Yun has swindled a lot of money from his elder brother Fang Tian, and the stack in his hand is as much as twenty or thirty taels.

  The shopkeeper's eyes widened as he saw Fang Yun's silver ticket, and an evil thought involuntarily rose in his heart. Looking at Fang Yun's eyes, there was always a hint of unnaturalness.
