Ryan Bennett could be one hundred percent certain that his eyes had never shown any sign of double pupils before; in other words, the double pupils appeared only after he was injured. However, Ryan Bennett's memory of the robbery incident only lasted up to the moment when a flash of fire appeared before his eyes. After that, when he woke up, he was already lying in the hospital. As for what exactly happened during that period, he had no way of knowing.

Picking up the mirror again, Ryan Bennett began to observe himself once more. Just like last time, although that aura in his eyes shot toward the mirror with his gaze, the mirror showed no change, and his gaze did not penetrate it. Ryan Bennett only felt that the aura seemed to circle around the outer edge of the mirror before retracting back into his eyes.

Unwilling to give up, Ryan Bennett found a book, "Kangxi the Great" by Er Yuehe. Ryan Bennett liked to read historical books in his spare time, and he had just bought this set not long ago. He had asked Boss to bring it from his place to the hospital. While in the hospital, his mother would often read it to him to pass the time. Since he didn’t return to his residence in Zhonghai after being discharged, he just carried it with him.

Ryan Bennett placed the thick, five-hundred-page "Kangxi the Great" in front of his eyes without opening it, then focused his gaze on it. As before, a flash of blue-green light appeared, extremely brief. After the blue light faded, the aura in his eyes also touched the book’s cover.

Ryan Bennett felt a bit nervous. If he could only see through clothes, it wouldn’t be very useful—was he supposed to use this special ability just for peeping? Ryan Bennett told himself he wasn’t that low.

When his gaze landed on the pages, Ryan Bennett breathed a sigh of relief, because the four big characters "Kangxi the Great" instantly became blurry, as if ice melting in water, only much faster. In almost an instant, the image of the person in dragon robes sitting on the throne disappeared, and what appeared before his eyes was line after line of densely packed black text, crystal clear.

It was page 397. When retracting the cool aura, he had paid special attention to the page number. After the aura returned to his eyes, Ryan Bennett didn’t feel any discomfort. He quickly turned to page 397, and the familiar text further confirmed his judgment.

He picked up the book again and placed it about a meter away from himself, then looked at it once more. To his surprise, Ryan Bennett found that the aura didn’t touch the book; when it was still more than ten centimeters away, it actually turned back into his eyes on its own. All he could see was the book’s cover—without the aura, he could no longer see through it.

Ryan Bennett started getting busy, making every item in the train compartment his test subject—even the metal kettle wasn’t spared. He tested the distance from near to far. Fortunately, looking at inanimate objects didn’t consume the cool aura in his eyes, so after more than an hour of experimenting, Ryan Bennett finally stopped.

After several experiments, Ryan Bennett categorized his findings. First, the cool aura in his eyes would diminish significantly when used on human bodies. Although experiments on his own arm showed that the aura was beneficial and harmless to his arm, it was actually damaging to his eyes. The cool aura that originally filled his eyes was now, after the morning and recent consumption, just a thin layer clinging to his eyes.

After these ten or so days, Ryan Bennett had gotten used to the presence of the cool aura in his eyes. It kept his eyes in an indescribable but very comfortable state at all times. The benefits of this aura to his eyes were obvious, and Ryan Bennett didn’t want to use it up and make it disappear. So he didn’t dare use his body for further experiments, but the idea that the aura was beneficial to the human body was confirmed in his recent tests.

Secondly, using the aura in his eyes allowed him to see through objects with simple molecular structures, like clothes and books. In his recent experiments, apart from quilts, clothes, and books, other items in the compartment—such as metal, glass, and the plywood compartment walls, which were denser—could not be penetrated by the cool aura in his eyes. However, looking at these things didn’t consume the aura, which reassured Ryan Bennett.

Another point was that after the cool aura left his eyes with his gaze, it had a distance limit. If it didn’t touch another object within about eighty centimeters, it would automatically return to his eyes, and its quantity would neither increase nor decrease.

After more than an hour of experimenting, Ryan Bennett felt that the aura in his eyes seemed to have a mind of its own, so he simply gave it a name: spiritual energy.

Having figured out these rules, Ryan Bennett felt a bit of a headache, because the spiritual energy in his eyes was rather unpredictable. Whenever he focused his gaze on an object, it would come out with his gaze, beyond his control—or rather, he hadn’t yet found a way to control it. It didn’t matter when looking at objects, since it didn’t harm either the objects or himself, but when looking at people, it was bad for him. The urgent task was to find a way to control this spiritual energy.

“It seems there was one time when I was able to retract the spiritual energy.”
