Xiao Fei picked up and put down several body-refining cultivation methods, finally settling on one called the "Golden Arhat Technique."
This technique originated from Buddhism. Buddhist cultivators were rare on the Eastern Continent, existing only in a few countries.
The "Golden Arhat Technique" strengthened the body from the inside out.
It began by refining the internal organs. Once the organs were strong, they would lead to the strengthening of the body's limbs.
Upon mastering this technique, one's entire body would turn golden when circulating the energy, presenting a magnificent appearance and possessing incredible resilience, capable of shattering large stones with a chest blow.
However, to practice this technique, one must first undergo marrow cleansing and tendon washing with rare spiritual herbs!
Xiao Fei was quite fortunate. Recently, while extracting medical fees from a patient, he had acquired many rare treasures.
Among these were various spiritual herbs capable of cleansing marrow and washing tendons.
The highest quality among them were the Tendon-Washing Vine and Bone-Forging Root. Xiao Fei had long since transplanted these spiritual herbs into his space.
Now, several seedlings had been propagated within the space, serving as future breeding stock.
Using the Tendon-Washing Vine and Bone-Forging Root as primary ingredients, Xiao Fei personally researched and refined a new pill, naming it the Tendon-Washing Bone-Forging Pill.
This pill could cleanse marrow, wash tendons, and strengthen bones.
Xiao Fei took one pill and immediately felt a surge of medicinal power coursing through his tendons and bones, expelling accumulated metabolic waste from his body.
As the medicinal effects of the pill completely dissipated, Xiao Fei stood up, feeling significantly lighter.
He stretched his limbs, then sat cross-legged once more, silently reciting the incantations of the "Golden Arhat Technique." A stream of spiritual energy rose from his dantian, flowing into his kidneys.
The cultivation process was extremely arduous and gruesome, posing a severe test of one's character and willpower.
Xiao Fei forcefully restrained his mind, focusing on circulating the "Golden Arhat Technique."
A continuous flow of spiritual energy was converted into essence within his kidneys, causing his head to buzz and his mind to become hazy.
Just as he felt he could no longer bear it, a thunderous roar erupted in his mind, as if a new world had opened its doors to him.
At this moment, his mind became exceptionally clear, all distracting thoughts vanished. Waves of power surged from his kidneys, rising to the crown of his head, and then, like a clear spring, flowed downwards, permeating every bone in his body.
Nourished by this power, his bones were growing stronger.
This round of cultivation primarily focused on strengthening his kidneys, brain marrow, and all the bones in his body.
In Xiancheng, Qin Kingdom, the Great General had been feigning illness and absent from court for half a year.
He had confined himself to a secret chamber and had not emerged for several months.
He could no longer control his emotions, his mind filled with malevolent thoughts. Any slight inconvenience would make him want to kill, and the more brutal the method, the more excited he felt.
He was now emaciated, his thoughts chaotic, and several parts of his body festered, with pus continuously flowing from the wounds.
The servants in the mansion had long been startled into becoming jumpy, and whenever possible, they would distance themselves from him.
On this day, a communication talisman flew into the secret chamber where the Great General resided.
"Reporting to the Great General, a cultivator has appeared in the Lü Kingdom's immortal cultivation world, possessing special means to treat cultivators parasitized by demon seeds..."
After examining the contents of the talisman, the Great General's face lit up with ecstatic joy.
"Hahahaha... Heaven has not abandoned me!"
Immediately, he circulated his spiritual energy, concealing the festering wounds on his body, making him appear much more normal.
He tidied his robes, then transformed into a streak of rainbow light, flying out of the Great General's mansion.
After leaving the city, the Great General flew through the air, full of spirit, his face sometimes contorted with ferocity, and sometimes beaming with a smile.
However, a golden seal at the Great General's waist continuously emitted strands of destiny energy that integrated into his body.
This destiny energy only disappeared completely after he had flown out of the Qin Kingdom's borders.
At this moment, the Great General, who was in mid-flight, plummeted rapidly, landing in a desolate wasteland.
"Ahhhhhh..."
Piercing screams echoed for miles, and his aura as a late-stage Nascent Soul cultivator startled the surrounding insects and beasts into fleeing.
After landing on the ground, the Great General seemed to be enduring immense pain, rolling on the ground clutching his head.
His fingers dug deeply into his flesh without his awareness.
Gradually, a large amount of black mist began to emanate from his body. His skin split open, and a furry black hand emerged from the fissure on his back.
Then, a second black palm emerged.
With both palms exerting force simultaneously, pulling apart, a demon, covered in black fur and possessing nine eyes, burst forth from the Great General's back.
On the ground, the Great General's body was left as nothing more than a human skin.
