The cold, gloomy energy began to undergo a qualitative change, as if two completely different energies were interacting and merging with each other.

This was something William Carter had not anticipated. Originally, he intended to strengthen the cold, gloomy energy, but instead, he altered its nature, causing a qualitative transformation in their fusion.

“Extreme Spirit Cold Qi?” William Carter raised his eyebrows, only to discover that after the fusion of immortal energy and the cold, gloomy energy, it actually transformed into Extreme Spirit Cold Qi.

William Carter had never seen it before; he had only read about it in ancient texts. The so-called Extreme Spirit Cold Qi was an extremely frigid energy that could only be produced in a domain of cold that had existed for hundreds of millions of years.

For some cultivators who leaned toward yin attributes, Extreme Spirit Cold Qi was extremely precious, and when refining ice-attribute magical treasures, Extreme Spirit Cold Qi was an excellent natural treasure.

William Carter hadn’t expected that his unintentional action would artificially create Extreme Spirit Cold Qi, which truly surprised him.

However, this small amount of Extreme Spirit Cold Qi was useless for either cultivation or refining magical treasures.

William Carter’s gaze fell upon the old man. The old man was still staring at William Carter, and seeing William Carter’s serious expression, he found William Carter even more endearing.

There was quite a bit of cold, gloomy energy within the old man. If it could all be absorbed and then nurtured, it would be enough to refine an ice-type magical treasure.

However, given the old man’s physical condition, if a large amount of cold, gloomy energy were forcibly extracted, his body would likely collapse.

After all, the cold, gloomy energy had already become part of the old man’s battle qi. Although this portion of energy was of no benefit to him, over the years it had become deeply rooted in his body. If it were removed rashly, it would only worsen his condition.

William Carter looked at the old man with some difficulty. The old man smiled slightly: “Well? Have you thought of a way to treat me?”

William Carter was taken aback. He had been so focused on the cold, gloomy energy that he had neglected the most important thing—the old man’s illness.

William Carter felt a wave of frustration. He had fallen into his old habits from his previous life: whenever he saw something good, he forgot everything else.

A gentleman loves wealth, but acquires it by proper means. William Carter also had his own principles. When treating patients, the patient always came first. Of course, whether treating mortals or cultivators, William Carter never did it for free—this was also his principle.

Chapter 0007: Return After Departure

“Old sir, I’ll go back and consult my medical books, and come back tomorrow to help you.” William Carter said earnestly.

“Are you leaving?” The old man’s face showed a hint of disappointment.

“It’s not like I won’t come back. Let me check the books, and I’ll come back tomorrow to help you.” William Carter looked at the old man sincerely.

“All right.” The old man nodded gently.

William Carter returned to his own courtyard, his mind filled with thoughts of the old man’s illness. With the old man’s body in mind, he lightly extended his hand, and a ball of blue-green Extreme Spirit Cold Qi surged from his palm, causing the surrounding temperature to drop sharply.

There wasn’t much Extreme Spirit Cold Qi, only about the size of William Carter’s small fist, but even such a small amount was enough to make the temperature plummet.

William Carter clenched his palm, and the Extreme Spirit Cold Qi became more and more condensed in his hand. At this moment, the strength in William Carter’s palm was immense, and the blue light of the Extreme Spirit Cold Qi grew ever brighter.

Within the glow, the Extreme Spirit Cold Qi continued to contract, becoming smaller and smaller, until it finally condensed into a blue pearl the size of a fingertip, crystal clear and shimmering with a strange greenish hue.

William Carter was not refining it, merely using immortal power to forcibly compress the Extreme Spirit Cold Qi; its essence did not change, just like water turning into solid ice.

William Carter couldn’t help but feel a bit curious about the person who had injured the old man. The battle qi he cultivated actually had such a miraculous effect.

However, the fusion of immortal energy and this cold, gloomy energy to produce Extreme Spirit Cold Qi was an accident. Even the creator of this battle qi technique probably never imagined that his battle qi would transform into Extreme Spirit Cold Qi.

But now, the biggest headache was how to ensure the old man’s health while also expelling the cold, gloomy energy from his body.

If it had been right after the injury, even if William Carter had forcibly expelled the cold, gloomy energy, it wouldn’t have been a big deal. But now, the cold, gloomy energy had already taken root and completely fused with the old man’s own battle qi.

At this point, forcibly removing the cold, gloomy energy would be no different from cutting a piece of flesh from the old man.

However, this cold, gloomy energy absolutely could not remain in the old man’s body. Otherwise, his body would eventually be destroyed by the clash of two different types of battle qi.

Just then, the roar of The Fourth Carter came from outside the courtyard, and a figure appeared before William Carter like a fierce tiger descending the mountain, full of aggressive energy.

“Fifth! Let’s see where you run this time!” Olivia Carter stuck out her nose, looking fierce.

William Carter could already see, faintly, the makings of a shrew in Olivia Carter’s face as she grew older.

“If I wanted to run, could you catch me?” William Carter rolled his eyes at Olivia Carter.

Olivia Carter’s cheeks twitched slightly. Indeed, as William Carter said, his escape skills were the best in the The Carter Family, and just last night she had experienced William Carter’s ability to run firsthand.

“I don’t care, you have to compensate me for my Beauty Flower, or… or…” Olivia Carter suddenly hesitated, because she really didn’t know what William Carter was afraid of.

Drag him to see Dad? Dad now avoided the two of them as much as possible.
