He finally sensed a faint clue—what allowed him to withstand the sun’s scorching heat and harshness, the cool current rising from the top of his head, seemed to be the sunlight shining down on him.

It was as if he was absorbing the rays of sunlight that fell on him into his body, transforming them into a mysterious energy—namely, stellar source power.

What he was absorbing was not planetary source power from Earth, but stellar source power contained within the rays of the sun.

In shock, Brian Carter suddenly realized the truth.

Why had his cultivation shown no effect in the past few days, but now it did? Perhaps Earth was no longer suitable for cultivation, or maybe the city hospital simply wasn’t a suitable place.

In Slaughter’s memories, not every planet was suitable for cultivation. Planets could be classified as life planets, desolate planets, mineral planets, abandoned planets, and so on. Only life planets could be used for cultivation, and each planet also had a lifespan, which could be divided into birth, growth, healthy, active, declining, and death phases.

The same talent and the same cultivation technique could yield completely different results depending on the phase of the planet. On healthy and active planets, stellar source power was abundant and strong; one didn’t even need special techniques to absorb it—just living there allowed one to be immersed in stellar source power, gradually transforming the body and growing stronger. But on declining planets, many areas had already run dry of source power or were extremely weak. No matter how outstanding the genius or how good the technique, in places without stellar source power, cultivation was simply impossible.

On declining planets, only a few extremely rare regions would still retain relatively dense stellar source power.

When he first saw this, because Slaughter’s memories were so vast and wide-ranging, if he tried to analyze every detail, Brian Carter would never finish even in a lifetime. But now he completely understood: Earth might have already passed its prime for cultivation, and stellar source power was scarce. Ordinary techniques could hardly absorb any stellar source power anymore.

Of course, there might still be a few exceptional places with relatively dense stellar source power, such as famous mountains and great rivers—those places could be used for cultivation, but the city hospital was not one of them. No wonder his cultivation had no effect here.

That’s why, when he tried to cultivate over the past few days, he had tried dozens of techniques with no results.

But now, the stellar source power he could absorb for cultivation didn’t come from Earth—it came from the sun!!

The sun was also a star, and it too contained stellar source power.

Not all stars were empty inside. In Slaughter’s memories, there was a terrifying alien race in the vast starry sky that was born inside stars, growing strong by absorbing stellar source power from within.

Stars also had cycles: birth, growth, health, activity, decline, and death.

Whether the sun above his head harbored life, no one could say for sure, but it should be a star rich in stellar source power—otherwise, Brian Carter wouldn’t be able to absorb any cultivatable stellar source power from it now.

“This technique actually absorbs stellar source power from a star. Doesn’t that mean I can only cultivate when there’s sunlight? I won’t be able to cultivate at night?”

A flash of shock crossed his eyes, and Brian Carter’s breathing rhythm was suddenly thrown off, so agitated that he couldn’t maintain it.

As soon as his rhythm was disrupted, his body—which had just felt comfortable and free from any heat—quickly became hot and restless again under the sun’s exposure.

Brian Carter composed himself and once again entered that marvelous breathing rhythm. The scorching rays shining on him immediately turned cool and pleasant again.

For most people, mastering a cultivation technique correctly would take quite some time. But Brian Carter had no such trouble. As long as it was a technique Slaughter had practiced, all he had to do was recall it, and it would feel as if he had just done it himself moments ago. As long as he adjusted his state to match his memory, he could master it with ease.

Feeling the layers of light bring comfort once again, Brian Carter silently warned himself: although this technique didn’t require any special posture, maintaining this marvelous frequency still consumed a certain amount of mental energy.

Of course, it didn’t require his full attention, nor did it prevent him from doing anything else. He just needed to devote part of his mind to maintaining it. As long as his emotions didn’t fluctuate too much—so much that he forgot to breathe—he could easily cultivate while doing other things.

This was just the beginning. Once he practiced longer and made this breathing rhythm instinctive, it would take even less effort.

Entering the state once more, Brian Carter resumed walking, a thought flashing through his mind: if this was a technique for absorbing stellar source power, then in the future, he really could only cultivate where there was sunlight.

But even so, it didn’t matter. His job was delivering packages—if anything, he had plenty of sunlight.

As long as he got used to the rhythm and kept his emotions steady, he just needed to devote a bit of attention to maintain it.

Still, Brian Carter felt a bit of amazement and doubt at the wonder of this technique.

He was standing on Earth, yet absorbing stellar source power from the sun.

And how far was Earth from the sun?

“To be able to absorb stellar source power from such a distance—this is definitely not something ordinary techniques can do.” With this rough judgment, Brian Carter felt another surge of joy. In Slaughter’s memories, cultivation techniques were also divided into levels.
