Cultivating the Muscle-Tendon Changing and Marrow Cleansing Classic

Chen Yuan stared fixedly at the words "Brain Domain Width": "I'm not surprised that it can improve my aptitude, but the fact that it can even increase my Brain Domain Width... this Optimization System is truly formidable."

Chen Yuan knew that in this world, Brain Domain Width represented the most intuitive measure of cultivation aptitude, aside from one's bloodline.

Bloodline goes without saying; the bloodline of Earthlings is considered bottom-tier in the universe, so everyone starts from the same baseline.

Therefore, given the same bloodline rank, whoever has a higher Brain Domain Width possesses better aptitude!

For every single point of Brain Domain Width gained, one could leave millions of others in the dust.

"What is my current Brain Domain Width?" Chen Yuan wondered. As his thoughts stirred, new information appeared on the panel.

Brain Domain Width: 15

"My Brain Domain Width is 15?" Chen Yuan took a deep breath.

To be honest, it wasn't considered high, but among the billions of people on Earth, it was already enough to rank in the middle tier.

"Not bad, better than I had imagined."

Chen Yuan's eyes brightened: "The important thing is that if I cultivate the Muscle-Tendon Changing and Marrow Cleansing Classic, I can increase my Brain Domain Width to a maximum of 18."

"A Brain Domain Width of 18 is enough to lead 99.99% of the people on Earth."

Do not underestimate a mere 3-point increase; in reality, it would reach the highest level in history prior to the emergence of Luo Feng.

This was because Chen Yuan clearly remembered that the purpose of the Ancient Civilization Ruin No. 9 on Earth was to screen for geniuses for the Yunmo Planet.

Anyone could enter Ancient Civilization Ruin No. 9, but only those with a Brain Domain Width of 18 or higher could enter the "Elite Passage" to undergo a special assessment.

And before Luo Feng's rise, not a single powerhouse in the entire world had been able to open the Elite Passage, including Hong and Thor!

"Ruin No. 9 shouldn't be closed yet; after all, it is the only place on Earth that produces the Black God Set," Chen Yuan mused. "Then, when I have time in the future, I can plan for the qualification to enter Ruin No. 9. A Brain Domain Width of 18 should be enough to open the Elite Passage."

"I remember that after Luo Feng completed the assessment in Ruin No. 9, he obtained a set of basic secret techniques for a Psychic Master, as well as the secret technique for using the Sky-Escaping Shuttle."

"If I go for the assessment, I should also be able to obtain a set of secret techniques related to Martial Artists from it. This is the only way for me to acquire cosmic-level secret techniques while on Earth."

However, entering Ruin No. 9 requires at least the strength of a War God, and that goal was still too far away for Chen Yuan.

For Chen Yuan, the most important thing right now was to cultivate the Muscle-Tendon Changing and Marrow Cleansing Classic.

Chen Yuan claimed the contents of the Muscle-Tendon Changing and Marrow Cleansing Classic and scanned through them carefully.

The entire manual contained about five thousand words and featured three cultivation methods that needed to be practiced in tandem.

The first method involved practicing 12 different postures. Chen Yuan looked at the illustrations and felt they resembled yoga, but were far more complex; some of the postures didn't even seem humanly possible.

The second method consisted of stance training and breathing techniques. This part covered the essentials of various stances and breathing patterns, which were not difficult.

The third method was the medicinal bath! This section only contained the formula for one type of medicinal agent and the list of required herbs.

"According to the instructions in the manual, the stance training and breathing techniques must be performed in conjunction with the medicinal bath. One must stand in the bath while breathing, with the medicinal water submerged up to the neck." Chen Yuan nodded as he reviewed the various points of the Muscle-Tendon Changing and Marrow Cleansing Classic. "Hmm, these herbs are quite common and can be bought through Limit Home. I also need to buy a sufficiently tall bathtub; the one at home won't accommodate the stance training."

After finishing the manual, Chen Yuan reopened Limit Home to purchase the items he needed.

He clicked pay, confirmed, and 30,548 yuan was deducted, leaving a balance of 817,852 yuan.

The various herbs for the medicinal bath cost the most, totaling 30,000 yuan, followed by the 500 yuan for the tall bathtub, and 48 yuan for the takeout Chen Yuan had ordered on a whim.

After all, he had been researching for so long that it was already midday.

Since it was same-city delivery, everything he bought was delivered to the entrance of the Mirror Lake Residential District in just about an hour.

Chen Yuan spent ten minutes carrying the items from the entrance of the residential district back to his villa, then began sorting the bags of herbs and mixing them according to the specified ratios.

Another half hour passed.

"Done."

Chen Yuan looked at the herbs, now evenly divided into ten portions, and nodded with satisfaction: "Exactly ten days' worth. After ten days, I'll decide how much more I need based on my cultivation progress."

Afterward, Chen Yuan began brewing the medicinal agent for the day. The agent needed to simmer for an hour, so Chen Yuan took the opportunity to eat his takeout, then headed to the martial arts hall on the second floor to begin practicing the twelve movements from the manual.

"Hiss."

"This is hard."

Chen Yuan was drenched in sweat from the pain; his body was twisted together, curled into a ball.

"Hold on, this bit of pain is nothing." Chen Yuan gritted his teeth and persisted, counting to thirty seconds in his heart before relaxing his body.

"It really hurts." Chen Yuan grimaced as he looked at the second movement. "Continue!"

"Hiss!" "Oh!" "Ugh!"

Cries of pain echoed from the martial arts room from time to time, but he did not stop.

It wasn't until an hour later, when the alarm Chen Yuan had set went off, that he slowly walked out of the martial arts room.

"Whoever designed these movements is a sadist; they aren't even human movements." Chen Yuan hissed through his teeth, feeling the soreness. "Oh, it was the system. Never mind then."

He had chosen this cultivation method himself, so he had to finish it even if he had to cry.

He went to the kitchen to turn off the stove, poured out the medicinal liquid, filled the bathtub with hot water, and poured the liquid in, stirring it to mix.

After the preparations were complete, Chen Yuan took off his shirt, stripped down to his boxers, and jumped into the tub.

Chen Yuan stood in a horse stance within the wooden tub, his chest rising and falling in a rhythmic, specific cadence as he began his breathing exercises.

"So comfortable..."

Chen Yuan felt as if he were drifting off to sleep; compared to the twelve movements of his physical training, practicing his breathing technique while standing in a medicinal bath was not only painless but grew more comfortable the longer he persisted.

Without realizing it, Chen Yuan seemed to have truly fallen asleep, standing motionless in the water, his chest barely rising or falling at all.

Time slipped away bit by bit until the medicinal liquid in the tub had gone completely cold, at which point Chen Yuan suddenly opened his eyes: "Did I fall asleep? No, that was Deep Sleep!"

He checked the time and his eyes widened: "Three hours?"

Splash!

Chen Yuan pressed his hands against the edge of the tub and vaulted out, grabbing a towel to dry himself as he walked toward the door.

"I actually entered Deep Sleep while standing in a horse stance, even though I already slept this morning." Curious, Chen Yuan opened his panel: "Let's see if there's any impact."

"My strength rose slightly, but not by much. The proficiency of the Hibernation Method increased, which is within expectations. As for the Muscle-Tendon Changing and Marrow Cleansing Classic..." Chen Yuan suddenly froze, his footsteps coming to a halt, "It jumped straight to 9.85%?"

"According to the manual, to completely alter one's marrow and bones, it takes one hundred days—the Hundred-Day Foundation Building." Chen Yuan recalled the contents of the Muscle-Tendon Changing and Marrow Cleansing Classic, "But this cultivation can be accelerated, and the shorter the time taken to complete it, the better the results. The Perfect Level is thirty days!"

"Because compressing one hundred days of cultivation into a single month puts the body under greater pressure, the resulting transformation is far more astonishing."

"The manual just didn't specify how to accelerate it." Chen Yuan stared at the panel, lost in thought, "So, when I entered the Deep Sleep state while standing in a horse stance, all the cosmic energy I absorbed was converted into proficiency?"

"This is a good thing." Chen Yuan's eyes brightened, "Increasing proficiency by 9.85% in one day means I can reach the Proficient stage in eleven days, and reach the Perfect Level in just over thirty days."

Chen Yuan knew that the panel categorized proficiency into four levels: Beginner, Proficient, Mastery, and Perfect Level.

Among these, the Perfect Level represented the point where the progress bar reached 100% after Mastery; it was merely a sign of reaching the peak of cultivation, not a separate realm.

In other words, each secret art had a total of three stages of proficiency, totaling 300%.

If the cultivation progress for the Muscle-Tendon Changing and Marrow Cleansing Classic did not diminish later on, he would only need thirty-some days to master this secret art, nearly achieving the most perfect result possible.

"One month." Chen Yuan was filled with anticipation, "In just one month, I can reach the Perfect Level, and my Brain Domain Width will increase by 3 points."
