William Clark had studied medicine with his grandfather since childhood. Although he hadn’t treated many people, the years of learning were not in vain. After several hours of effort, William Clark had already integrated a portion of George Washington’s memories from before he became a celestial master, specifically those from his mortal life. While he couldn’t claim complete mastery over everything George Washington knew, he had grasped most of it, especially in medicine and calligraphy. Thanks to his grandfather’s early teachings, what William Clark lacked in medicine was practical experience. George Washington, on the other hand, had traveled the world as a wandering physician in his youth, accumulating a wealth of experience. Through the fusion of memories, all this experience became William Clark’s own. George Washington’s medical skills were also passed down through his family—his ancestor had been Hua Tuo’s last disciple. So now, William Clark could be considered a distant successor of Hua Tuo’s school.

Therefore, William Clark was very clear about his own physical condition. Aside from some weakness and a minor scalp injury, he was in excellent health. When Brian Cooper saw that William Clark was determined to be discharged, he said, “Lie down for a bit, I’ll go ask the doctor.” With that, Brian Cooper left the ward to find a doctor.

William Clark lay on the bed with his eyes closed, resting. Suddenly, he felt the three items in his mind emit a beam of light that shot into his eyes. He felt a swelling sensation in his head, and a burning, stinging feeling in his eyes, causing two streams of murky, blood-streaked tears to flow uncontrollably down his cheeks.

When the stinging in his eyes faded, William Clark sensed a subtle, mysterious connection between his eyes and the glowing patterns of the three items in his mind. He took a tissue to wipe his eyes and opened them.

As soon as William Clark opened his eyes, he felt as if the entire world had lost its color, leaving only black and white. He was startled: “Have I become colorblind?”

Startled, the connection between the mysterious patterns and his eyes was instantly severed. A wave of pain surged through his eyes. He quickly closed them, and when he opened them again, the world had regained its color.

William Clark sensed that the connection between the patterns of the three items in his mind and his eyes seemed to have been interrupted. Could it be...

He got out of bed and walked to the windowsill, where there was a palm-sized mirror. Looking into it, aside from a slight pallor, he saw nothing unusual. Bringing the mirror closer, he focused intently on his own eyes and felt the mysterious patterns in his mind once again connect with his eyes. This time, there was no burning or stinging sensation.

The moment a strand of the mysterious pattern fully connected with William Clark’s eyes, he clearly saw his own eyes begin to change color. The black pupil of his left eye slowly faded away, turning the entire eyeball white, while the black pupil of his right eye gradually expanded until the whole eye became black.

The instant the transformation was complete, William Clark’s eyes returned to normal. Although it lasted only a fleeting moment, William Clark was certain he hadn’t imagined it, because the world in his eyes had turned black and white again, completely devoid of color.

Though his eyes had returned to normal, they now lacked a certain vitality and liveliness. Anyone who saw them would feel a sense of dryness and desolation.

What was going on? For a moment, William Clark felt his scalp tingle. He staggered back onto the hospital bed, took a deep breath, and slowly calmed himself. Picking up the mirror again, he thought to himself, “Disconnect the link.” Sure enough, he felt the connection to his eyes slowly withdraw back into his mind, merging once more with the patterns. His eyes and the black-and-white world he saw gradually regained their color and vitality.

Chapter 5: Yin-Yang Eyes (2)

After experimenting several times, William Clark found that he could control these changes at will. He let out a soft sigh and pondered what was happening. He slowly searched through George Washington’s memories. Although he had inherited George Washington’s thousand years of insight and experience, the sheer volume of information meant that most of it was locked deep in his mind, with only a small portion from George Washington’s mortal days having been integrated.

But within these memories, he found no explanation for the changes in his eyes. Suddenly, a flash of inspiration struck him: “Could it be... could this be the so-called—Yin-Yang Eyes described in George Washington’s legend?”

To test his theory, William Clark focused his mind again, and the mysterious patterns once more connected with his eyes. The world in his vision quickly faded to black and white.

The hospital room where William Clark stayed was a four-bed ward. Two of the beds were occupied by patients who were both unconscious, having undergone craniotomies for severe cerebral hemorrhage.

Looking at the two people in the black-and-white world, William Clark saw a large and a small cloud of black mist floating above their bodies. The two clouds of black mist rolled and shifted into various shapes above them. With each roll, the larger cloud diminished slightly, while the smaller one grew a bit. They waxed and waned, and soon the smaller cloud became the larger, and the larger became smaller.
