It takes madness to achieve greatness. Stirling inexplicably recalled this sentence from Earth before his transmigration.

  Stirling also remembered his helplessness when facing Lilith during the day. In that instant, a gentle breeze swept through his heart, like the bright moon shining on a river. With his expressionless face, he silently uttered the word yes.

  All in, it's ultimate wisdom!

  [Nine Heavens and Ten Earths Transforming Malice Technique]

  The Heavenly Palaces are just fleeting evil gods. The ultimate path in the mortal world is simply the rise and fall of aether and blood. Take the malice of the world to achieve your eternal merit. This path is for refining as well as killing.

  Nine Heavens and Ten Earths Transforming Malice Technique?

  Stirling‘s heart was pounding so hard that he almost cried out. He could not wait but looked at the brand-new book before him. His hand trembled, and he almost dropped the book. From the domineering name alone, he knew this technique was absolutely extraordinary.

  Stirling hurried to glance at the kitchen doorway. Seeing nothing wrong, he read the book in the dim light of the oil lamp.

  This manual, spent by Stirling over seventy years, had a rune on its first page that he knew well.

  Stirling was taken aback, somewhat puzzled. But then, Stirling immediately noticed the rune's unusual nature. Stirling had copied the malice-breaking rune from the Yearning Palace many times. This time, he saw the new was more symmetrical and complete. It also had a unique, mysterious charm.

  Stirling admired the rune. Then, he turned to the second page and studied it with scrutiny.

  After a moment, Stirling put down the book; his eyes gleamed.

  Stirling immediately assumed an odd sitting posture and began circulating his aether flow.

  During the enhancement process, Stirling added a attribute. It must have had a strong link between the technique and him. The technique explained internal energy, Isn't that the Aether inside his own body?

  Stirling focused on his aether. He pictured the mysterious rune in his mind. Then, he pressed on several acupoints on his body, as the book described.

  Temples, Adam's apple, heart, groin...

  It seemed Stirling's body got used to the aether flow for a long time. After just a few repetitions, the Aether left faint traces in those acupoints. With each complete cycle in his body, the Aether flow at these points grew stronger.

  If an X-ray machine shone on Stirling now, it would show something fascinating. Connecting the acupoints recently opened on his body would trace out lines. These lines would form the mysterious runes from the Malice-Refining Technique.

  Taken from Royal Road, this narrative should be reported if found on Amazon.

  The core of this divine skill is to treat the human body like an alchemical furnace. Here, Malice acts as the metal. By melting it down, people create an essence that nourishes the whole body!

  Stirling was deep in cultivation for a while. Then, he abruptly realized something. He opened his eyes and looked ahead.

  Invisible Malice rose from the ground. It changed into smoke and drifted towards Stirling.

  This daily Yearning Malice arrived as scheduled.

  Stirling reflected, and all the acupoints in his body shook at once. The aether linked them together, creating a line. In an instant, Stirling absorbed the surrounding malice into his body as if a whale absorbed water!

  After entering Stirling's body, the Malice turned into warm wisps straight away. These rushed down from his head and spread through his limbs and bones.

  Right now, Stirling feels his skin strengthening again. The outer layer seems to change under the aether's stimulation.

  Stirling understood, excitement gleaming in his eyes.

  The pinnacle of a realm—Stirling had thought it was just a legend. But now he was experiencing it firsthand; it was unbelievable.

  This was the dream realm for all samurai, but it felt the most unattainable!

  Stirling's thoughts stirred, and the wisps of heat within his body immediately ceased. He then reversed the path of the aether flow by following the book's instructions. In a flash, the malice flooding into his body came to a halt and vanished without a trace. Right now, Stirling saw a new notification appear before him:

  [You have refined a trace of Yearning's Malice, lifespan +0.1 days]

  [You have refined a trace of Yearning's Malice, lifespan +0.1 days]

  ...

  The familiar notification text appeared before Stirling's eyes, completely dispelling his doubts.

  This path is for refining and also for killing.

  Forward to refine, backward to kill. How to move depends on my will. Throughout the nine heavens and ten earths, I am the supreme ruler.

  Each day, the Yearning malice existed for only two hours. Afterward, Stirling chose not to extend his lifespan. Instead, he switched back to the energy-absorbing mode. He greedily absorbed the Yearning malice in the air. This propelled the skin barrier towards its ultimate state.

  After two hours, the Yearning's malice in the void disappeared little by little. Stirling noticed this, and his furrowed brow unwound.

  Stirling refined two hours of Yearning's Malice tonight. This nourished the skin barrier. Still, he sensed that the skin-barrier's ultimate state had only improved a little. Without a doubt, this slow progress was related to the concentration of the Yearning malice and the density of the aether within his acupoints.

  After all, it was only the start of practicing this technique, and little had progressed.

  This technique only worked for Stirling. If others tried it, they wouldn't know where to start. Getting to the basics would take an uncertain amount of time. By taking the first step, Stirling put himself at odds with the world's cults. Any exposure would mean being besieged by all the divine temples and palaces of the world. The road ahead was fraught with peril, yet it was also filled with light!

  Stirling looked at the book in his hand, then glanced at the kitchen door. After a moment's thought, he tore off a piece of cloth from the lining, shaped it into a pouch, and wrote "Void Storage" on it.

  Immediately afterward, he placed the pouch before his eyes. In less than three breaths, a line of text appeared:

  [Current enhancement required a lifespan: 615 years and 18 days. Enhance?]

  Damn it! Enhance my arse!

  Stirling didn't think he would succeed. But the need for six hundred years made his eye twitch.

  Without a doubt, anything related to immortals requires an absurdly long lifespan. Stirling recalled trying to improve an immortal cultivation technique months ago. It needed over 1,000 years!

  Stirling thought, rolling up the book and tying it to the inside of his thigh, a sneer spreading across his face.
