Cultivating the Muscle-Tendon Changing and Marrow Cleansing Classic

Chen Yuan stared fixedly at the four words "Brain Domain Width." "I'm not surprised it can improve aptitude, but it can even raise Brain Domain Width. This Optimization System is seriously impressive."

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

Bloodline went without saying. Earthlings had a low-tier bloodline in the universe, and everyone started from the same point.

So, with the same bloodline level, the higher one's Brain Domain Width, the better one's aptitude!

Every one-point increase in Brain Domain Width could leave millions, even tens of millions, of people behind.

"What's my Brain Domain Width right now?" Chen Yuan wondered. As the thought crossed his mind, new information appeared on the panel.

Brain Domain Width: 15

"My Brain Domain Width is 15?" Chen Yuan drew in a breath.

Honestly, it was not particularly high, but among the billions of Earthlings, it was already around the middle range.

"Not bad. Better than I imagined."

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

"An 18-point Brain Domain Width is enough to surpass 99.99% of people on Earth."

It might have only been an increase of three points, but in reality, it would reach the highest level in history before Luo Feng emerged.

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

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

Before Luo Feng rose to prominence, not a single powerhouse in the world had been able to activate the Elite Passage, including Hong and Thor!

"Ruins No. 9 should still be open. After all, it's the only place on Earth that can produce the Black God Set." Chen Yuan pondered. "When I have the time, I can make plans to qualify for Ruins No. 9. A Brain Domain Width of 18 should be enough to activate the Elite Passage."

"I remember Luo Feng completed the assessment in Ruins No. 9 and obtained a set of foundational secret techniques for Psychic Masters, as well as the secret technique for using the Sky-Escaping Shuttle."

"If I take the assessment, I should be able to obtain a set of secret techniques related to Martial Artists. This is the only place on Earth where I can acquire secret techniques from the universe."

However, entering Ruins No. 9 required at least War God Level strength. That goal was still far too distant for Chen Yuan.

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

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

The entire manual contained roughly five thousand words and described three cultivation methods that needed to be practiced together.

The first involved twelve different postures. Chen Yuan looked at the illustrations and felt they had a hint of yoga to them, except they were far more complicated. Some of the poses hardly looked possible for a human body.

The second involved standing postures and breathing techniques. This section covered the essentials of various stances and breathing methods, and it was not difficult.

The third was medicinal baths! This section contained only the formula for a medicinal solution and the required herbs.

"According to the manual, the standing postures and breathing techniques need to be practiced together with medicinal baths. You stand and breathe in the bath, with the medicinal water submerged up to your neck." Chen Yuan looked over the various key points of the Muscle-Tendon Changing and Marrow Cleansing Classic and nodded. "Mm, these herbs are fairly common. I can buy everything through Limit Home. I'll also need a tall enough bath barrel. The bathtub at home won't work for standing postures."

After finishing the manual, Chen Yuan reopened Limit Home and purchased what he needed.

He clicked to pay, confirmed it, and 30,548 yuan was deducted, leaving 817,852 yuan.

The various herbs for the medicinal bath cost the most, coming to a full 30,000 yuan. Then there was the 500-yuan bath barrel, as well as the 48-yuan takeout Chen Yuan had ordered on the side.

After researching for so long, it was already noon.

Since everything was delivered locally, all the items he bought arrived at the entrance of Mirror Lake Residential District in just over an hour.

Chen Yuan spent ten minutes hauling everything from the residential district entrance back to the villa. Then he began sorting the bags of herbs and mixing them together in set proportions.

Another half hour passed.

"Done."

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

Chen Yuan then began brewing today's medicinal solution. It needed to simmer for an hour, so he used the time to eat his takeout before heading to the martial arts hall on the second floor to practice the twelve movements from the manual.

"Hiss."

"This is really hard."

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

"Endure it. This little pain is nothing." Chen Yuan gritted his teeth and persisted, silently counting to thirty before relaxing his body.

"It really hurts." Chen Yuan grimaced and looked at the second movement. "Keep going!"

"Hiss!" "Oh!" "Oof!"

Chen Yuan's cries occasionally rang out from the martial arts room, full of pain, but he never stopped.

It was not until an hour later, when his alarm went off, that Chen Yuan slowly walked out of the martial arts room.

"Who designed these movements? They're way too brutal. These are practically not human movements." Chen Yuan sucked in cold breaths with an expression of pained satisfaction. "Oh, the system did? Then it's fine."

I chose this cultivation technique myself. Even if I have to cry, I'll finish practicing it.

He went to the kitchen, turned off the heat, poured out the medicinal liquid, filled the bath barrel with hot water, and stirred the solution evenly into it.

Once the preparations were complete, Chen Yuan took off his shirt, wearing only a pair of shorts as he jumped into the bath barrel.

Chen Yuan assumed a standing posture in the bath barrel. His chest rose and fell as he began breathing to a specific rhythm.

"This feels so good..."

Chen Yuan felt as though he was about to fall asleep. Compared to practicing those twelve movements, cultivating the standing posture and breathing technique in the medicinal bath was not only painless, but actually became more comfortable the longer he practiced.

Before he knew it, Chen Yuan seemed to have truly fallen asleep. He stood motionless in the water, and even the rise and fall of his chest became faint.

Time passed bit by bit. Only when the medicinal solution in the bath barrel had completely cooled did Chen Yuan suddenly open his eyes. "Did I fall asleep? No, it was Deep Sleep!"

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

Splash!

Chen Yuan pressed against the edge of the bath barrel and sprang up, leaping out of it. He grabbed a towel nearby, wiping himself down as he walked outside.

"I actually entered Deep Sleep while practicing the standing posture, even though I'd already slept this morning." Chen Yuan curiously opened the panel. "Let's see what effect it had."

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

"According to the manual, completely changing one's physical foundation requires one hundred days, which is 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 fewer days it takes to complete, the better the results. The most perfect result takes thirty days!"

"Because compressing one hundred days of cultivation into one month puts greater pressure on the body, the transformation becomes even more astonishing."

"It's just that the manual doesn't explain how to accelerate it." Chen Yuan stared at the panel, lost in thought. "So, when I entered Deep Sleep while practicing the standing posture, all the cosmic energy I absorbed during that time turned into proficiency?"

"This is a good thing." Chen Yuan's eyes shone. "One day of cultivation increased proficiency by 9.85%. In eleven days, I can go from entry level to proficient level, and it will take only a little over thirty days to cultivate it to Completion Level."

Chen Yuan knew that the panel divided proficiency into four tiers: Entry level, proficient level, Great Accomplishment Level, and Completion Level.

Among them, Completion Level meant that the progress bar had reached 100% after Great Accomplishment Level. It could only be considered a sign that cultivation had reached its peak, not a separate realm.

In other words, each secret technique had only three stages of proficiency, totaling 300%.

If the cultivation progress of the Muscle-Tendon Changing and Marrow Cleansing Classic did not decrease later on, he would need only a little over thirty days to bring this secret technique to Completion Level, nearly achieving the most perfect result.

"One month." Chen Yuan was filled with anticipation. "In just one month, I'll cultivate it to Completion Level, and my Brain Domain Width will increase by three points."
