The “Primal Chaos Embryonic Breathing Sutra” is a cultivation method with a high entry barrier because it requires changing the breathing pattern, transforming the original breathing into embryonic respiration.

Cultivators often have to maintain the operation of their mana while constantly fighting against their breathing habits, constructing a new embryonic breathing system. As a result, many cultivators fail to even get started after ten days to half a month.

But for Zhang Yu, none of these were problems.

The “Primal Chaos Embryonic Breathing Sutra” involves the pores all over the body, as well as the increasingly complex meridians after Foundation Establishment. After spending more than thirty minutes, Zhang Yu finally circulated his mana for one cycle, completing one run of the “Primal Chaos Embryonic Breathing Sutra’s” energy circulation route.

In an instant, he felt scenes flashing through his mind, visions of himself diligently practicing the “Primal Chaos Embryonic Breathing Sutra” time and time again, finally mastering this cultivation method.

At the same time, Zhang Yu’s breathing became weaker and weaker, eventually approaching a state of nothingness.

And the skin all over his body transmitted a wave of cool sensations, which was the spiritual energy in the room constantly pouring into his pores, gathering into the mana circulation within his body’s meridians.

Zhang Yu could feel that, after entering the state of embryonic breathing, his pores all over his body were constantly absorbing the surrounding spiritual energy at all times, as if it had become his new breathing instinct.

After adapting for a while, Zhang Yu continued to circulate the “Primal Chaos Embryonic Breathing Sutra,” beginning the second round of practice.

At the moment when Zhang Yu transformed his breathing into embryonic respiration, Zhang Pianpian, who was originally closing her eyes in cultivation, suddenly opened her eyes, her gaze seemingly flashing with divine light, and looked at Zhang Yu beside her.

“Embryonic breathing?”

Zhang Pianpian thought to herself, “It seems that my brother has been pondering embryonic breathing cultivation methods during this time since school started.”

“Well, mastering the method of embryonic breathing, absorbing spiritual energy day and night, and refining mana, is of great benefit to the increase of mana.”

With a slight sweep of her gaze, Zhang Pianpian closed her eyes, and images from deep within the Spirit Realm emerged in her mind.

And Zhang Yu continued to diligently cultivate the “Primal Chaos Embryonic Breathing Sutra” in the following days, passively circulating it during class, and actively circulating it after class, never stopping his hard cultivation for a moment.

In just three or four days, he raised the “Primal Chaos Embryonic Breathing Sutra” to level 10, obtaining the level 10 cultivation effect, allowing the “Primal Chaos Embryonic Breathing Sutra” to have 100% of the effect of active circulation when passively circulated.

Then, more than ten days passed, and Zhang Yu even raised the “Primal Chaos Embryonic Breathing Sutra” to level 20 in one go. The level 20 cultivation effect made his mana circulation in the embryonic breathing sutra smooth and satisfactory, as if aided by the gods with every breath.

Originally, it took Zhang Yu more than thirty minutes to circulate the “Primal Chaos Embryonic Breathing Sutra” for one cycle, but now he could compress it to within twenty minutes, greatly accelerating his breathing efficiency.

His mana also increased all the way to 286.2 during the cultivation process, and the quality of his mana reached 113.

But just as Zhang Yu was planning to choose the next cultivation method, Zhang Pianpian found her younger brother while Yu Xinghan and Le Mulan were away.

Previously, at the end of June, Zhang Pianpian recognized that Zhang Yu had cultivated the method of embryonic breathing, and didn’t think there was any problem.

But in the next half month, she checked the spiritual energy consumption data of the dormitory and found that the spiritual energy consumption of the dormitory continued to increase, becoming higher day by day.

After noticing this, she paid more and more attention to why the spiritual energy consumption was increasing so fast.

Then she quickly discovered that the data of spiritual energy consumption accelerated every time Zhang Yu was in the dormitory.

“Is it because Zhang Yu’s breathing efficiency has become higher?”

After noticing that her brother’s breathing efficiency had become higher and his mana refinement had become faster, Zhang Pianpian’s first reaction was not to be happy, but to suspect.

“Has it increased so much in a short time? Did he spend a lot of spiritual coins? Or even… borrow money?”

Zhang Pianpian’s suspicion was not without reason. After all, Zhang Yu owed 700,000 when he was a freshman for three months.

It’s just that Zhang Pianpian was not worried about Zhang Yu’s debt. After all, Zhang Yu had already proven his talent in Immortal Dao, and how could Immortal Dao cultivation not borrow money? She was worried that Zhang Yu would waste money.

“The increase in mana is accumulated little by little over a long period of time.”

“Spending a lot of money on this every day is only suitable for the really rich, not for the poor.”

So Zhang Pianpian cast a spell and began to investigate Zhang Yu’s spending records, loan records, credit information…

Then she was even more surprised to find that Zhang Yu had been frugal since coming to the Ten Thousand Dharma University City for a month and a half. Besides buying many cultivation methods, he didn’t have any major expenses.

After eliminating the possibility of various money-burning behaviors, it seemed that only one result remained.

“My brother didn’t replace any dharma bodies, didn’t take any medicine, buy Daoist services, or use any means of spending money…”

Zhang Pianpian looked at the “Primal Chaos Embryonic Breathing Sutra” in the other party’s shopping record and thought, “In this short half month, his breathing cultivation method has been constantly and rapidly improved, which has caused the spiritual energy consumption to increase day by day.”

At this moment, only Zhang Pianpian and Zhang Yu, brother and sister, were left in the room.

Zhang Pianpian looked at Zhang Yu and asked, “Brother, tell me the truth, to what extent have you cultivated the Primal Chaos Embryonic Breathing Sutra?”

Zhang Yu was slightly stunned, and didn’t expect his sister to tell the cultivation method he practiced in one sentence.

Fuji quickly reminded, “Zhang Pianpian is a person of the Gods, you must not confess our affairs to her. Report a little less about the progress of the Primal Chaos Embryonic Breathing Sutra, lest it cause her unnecessary attention.”

Zhang Yu thought, “Level 20 in half a month is indeed a bit amazing.”

So, after thinking about it, Zhang Yu slowly said, “Level 10.”

“Level 10?” Zhang Pianpian’s heart skipped a beat, but she controlled the expression on her face without the slightest change, and said lightly, “Impossible, the level 10 Primal Chaos Embryonic Breathing Sutra has not really reached the Foundation Establishment level.”

“I have seen the spiritual energy consumption in the room and your consumption records in the past half month. Tell me the truth and don’t think about deceiving me.”

“How many levels is your Primal Chaos Embryonic Breathing Sutra exactly?”

Zhang Yu hesitated for a moment, and then said, “Level 15.”

Zhang Pianpian was shocked when she heard this, “Level 15? Cultivation to level 15 in half a month?”

“It is normal to spend a year and a half to cultivate the breathing method of the Primal Chaos Embryonic Breathing Sutra to level 15 by yourself. My brother only spent half a month.”

“If you want to spend spiritual coins to do this, how much money will it take? 50 spiritual coins? Or 100 spiritual coins?”

Zhang Pianpian sighed in her heart, “My brother’s talent seems to be more amazing than I originally expected.”

She remembered seeing “???” when she last used the Sky Eye Talisman to check Zhang Yu on the first floor.

“Well, if not, how can I keep up with me in the future?”

Thinking of this, Zhang Pianpian looked at Zhang Yu and said seriously, “Zhang Yu, I once told you the importance of information in Kunxu.”

“Mastering more information and having enough information difference is often more useful than strength, allowing you to overcome the strong with the weak and the rich with the poor.”

“We know this, and those gods, Golden Cores, Nascent Souls, and even higher immortals, of course, know this better.”

“So the supervision of information will be stricter on each floor of Kunxu. It’s like layers of spider webs covering everyone, wishing to monitor every bit of data on everyone.”

“Like the increase in spiritual energy consumption in your dormitory in the past half month, it can be easily found out.”

“If you don’t know how to hide it, as your future grades improve, someone will soon care about your various data and information, and it won’t be long before many people notice your amazing talent.”

Zhang Yu’s heart moved slightly when he heard this. The speed of his cultivation progress was indeed something he could not explain no matter what.

If a high-level existence became very interested in him, then his future destiny would be entirely in the other party’s mind.

Therefore, he has always been deliberately concealing this matter, and will not be too shocking.

This time, he did not expect that through the spiritual energy consumption data of the room, combined with his consumption records, he could infer that his breathing cultivation method was rapidly improving.

Zhang Pianpian continued, “So in addition to mastering the information difference, creating the information difference is also very important. And the simplest and most effective way for us poor people to create the information difference is to learn to hide our information.”

“You are cultivating mana to sell mana to make money, right? But with your talent, if you really increase a lot of mana in a short period of time to sell, it will immediately be a huge trouble of unknown origin of mana.”

Zhang Pianpian sighed and said, “So you have to learn to slow down your speed.”

“Like the Primal Chaos Embryonic Breathing Sutra, don’t improve it for at least half a month, you can focus your attention on physical strength or the direction of Dao Heart.”

Zhang Yu thought, “But I’m already level 20.”

Fuji reminded, “Don’t worry, Zhang Yu, with my anti-detection ritual, it’s not difficult to hide your strength.”

Detection rituals can detect cameras.

Anti-detection rituals can hide some data when detecting body data.

These two rituals were completed by Zhang Yu on the first floor.

But Zhang Yu still sighed in his heart at this moment, “Even if I can hide the speed of mana improvement, there is a risk of selling too much mana.”

“It seems that if I want to earn more spiritual coins, I still have to rely on the construction site.”

“Then the original cultivation plan will have to be changed.”

Zhang Pianpian continued to remind, “You should also pay attention to the ranking, don’t raise it too fast and attract too much attention.”

“Many exams in the university are application-based, and they are assessed whenever you apply. Try to delay the exam until the last time, so even if the grades improve a lot, there will be less attention.”

“By the way, don’t do the usual body refining cultivation in front of the dormitory door, go to a place without surveillance to practice.”

Zhang Yu asked curiously, “Where is there no surveillance?”

Zhang Pianpian said lightly, “Below the 100th floor of University City, the lower the floor, the less surveillance. Go there to practice.”

Zhang Yu asked again, “But what about the consumption of spiritual energy in the dormitory?”

I saw Zhang Pianpian reaching out and pointing, and a book of talismans appeared at the tip of her finger.

With the flash of runes, the log of spiritual energy consumption belonging to the dormitory has appeared in front of Zhang Pianpian, and was modified into another data as she moved her finger.

“It’s easier to hide the consumption of spiritual energy. I’ll help you hide it with a Spirit Stealing Talisman, but your own grades and strength still depend on you to restrain yourself.”

Zhang Yu asked curiously, “What is a Spirit Stealing Talisman?”

“A talisman that can secretly use more spiritual energy without being discovered. It’s a little thing I drew myself, don’t worry about it.” Zhang Pianpian smiled slightly, “After all, the dormitory on the 125th floor is relatively simple, and I have cracked the talisman that records the spiritual energy data.”

Fuji was shocked when she saw this scene, “Damn it… this is okay? Is she stealing electricity? This Zhang Pianpian… is she human or a god now?”

And Zhang Yu looked at his sister in front of him, and suddenly saw the information of Dao Seed flashing past her chest.

“Taiqing Talisman?” Zhang Yu thought, “Is this my sister’s Dao Seed?”
