With Henry Wallace's final move, it was as if a surge of blue flames suddenly ignited from the old man's body. Instantly, a miracle occurred.

Henry Wallace's dry and messy hair suddenly turned jet-black and glossy, flying and fluttering. His withered, decrepit skin instantly became taut and radiant. His once cloudy, lifeless eyes suddenly blazed with a fiery, piercing brilliance.

In the blink of an eye, Henry Wallace seemed to have become decades younger, transforming from a gray, withered old man into a strikingly handsome, elegant middle-aged man. Even the robe on his body, which had looked like a beggar's rags, instantly turned into a brocade robe adorned with vivid flame patterns, so lifelike they seemed ready to leap off the fabric.

This was the true appearance of Henry Wallace—imposing, awe-inspiring, and unrestrained.

“My vitality was too weak, so for the past year, Master couldn't teach you even a single move. But I can give you a far more precious gift: with my last strength, I will cleanse and refine your meridians.” Henry Wallace suddenly raised both hands, and at once, a surge of heat seemed to lift William Carter from below, causing his entire body to float in midair.

“In martial cultivation, the most important thing is cleansing the meridians. I say the human body's meridians are like countless rivers and streams, and the dantian is like a vast ocean. The waters of the rivers and streams all eventually converge and rush into the sea. Profound energy is like water; each practice session adds a stream to the dantian and meridians. But just like the rivers and streams of this world, over time, silt and blockages accumulate, and progress slows until it halts completely. So each cleansing of the meridians is like dredging and widening the riverbeds, allowing the flow of energy through the meridians to become smooth, so that the flow of profound power between the dantian and meridians surges unimpeded, making cultivation twice as effective with half the effort, advancing by leaps and bounds.”

“Today, Master will cleanse your meridians. However many layers you can cleanse depends on your own fortune.”

With that, a surge of powerful energy burst from Henry Wallace's palm and was injected into the sole of William Carter's right foot.

……

“Ah, so cold, so hot!” William Carter almost screamed, but not a sound could escape his lips.

It was truly strange. Henry Wallace cultivated pure yang profound power, like a raging fire, and when this power entered the body, it was not only scorching hot, as if it would burn one to ashes, but also extremely cold, as if it would freeze one to pieces.

“I possess a pure yang body and cultivate fire. But when cultivation reaches its peak, yang becomes yin, yin becomes yang, and the flames turn pure blue. At this level, there is no distinction between hot and cold—it is both extremely cold and extremely hot. It took me thirty-nine years to reach this realm. You possess the Nine Yang Profound Meridians; I believe you will need only a dozen or twenty years at most to reach this level. By then, the flame ring on your finger will become visible, and you can openly become the sect master of the Yin-Yang Sect.”

As Henry Wallace spoke, an incomparably powerful force continuously poured from the sole of William Carter's foot, advancing inch by inch along William Carter's blood vessels, truly cleansing every nerve ending without missing a single spot.

The entire process was excruciatingly painful. It was as if being burned by flames of thousands or tens of thousands of degrees, and at the same time assaulted by a chill of over a hundred degrees below zero. This pain was beyond words, and compared to this, the self-immolation William experienced before transmigrating was child's play.

The powerful profound energy cleansed William Carter's meridians inch by inch. At first, it could cleanse an inch per minute, but then it grew slower and slower, while William Carter's pain intensified layer by layer, until his entire skin trembled and shuddered. William Carter's body was half red and half blue, looking incredibly bizarre.

After more than half an hour!

The inhuman torment finally ended. William Carter was completely numb. The first cleansing of the meridians was over, and William Carter floated in the air, like a fish thrown onto the beach and left to bake in the sun, able to do nothing but gasp for breath. Yet his whole body felt an indescribable sense of comfort. From head to toe, his body was covered in greasy, black impurities—these were the blockages in William Carter's meridians, now cleansed by Henry Wallace. So although William Carter was numb with pain, he also felt an unspeakable lightness, as if a breeze was flowing through his meridians.

However, Henry Wallace now looked as if he had aged ten years. His once black and purple, flowing long hair now had a portion that was gray and white.

“Incredible. In just a quarter of an hour, you’ve cleansed the first layer of meridians. Compared to before, your cultivation speed after cleansing the first layer will be three or four times faster.”

“Truly worthy of the Nine Yang Body—astonishing. Even the speed of cleansing the first layer of meridians is several times, even dozens of times, faster than others. I remember when I first cleansed my meridians, it took me a whole day and night. And the profound energy you used for the first layer is only a fraction of what others would need. Such talent is truly remarkable.”

“I originally thought my remaining profound energy would only be enough to cleanse your first layer, but I didn’t expect that cleansing the first layer would use up only a fraction!”

“Now let’s continue. I want to see just how astonishing the Nine Yang Profound Meridians really are.”

With that, Henry Wallace pressed his palm down, and an even thicker, more powerful surge of profound energy suddenly shot into William Carter's right palm, the force four or five times greater than before.
