(Secondly, the most fundamental aspect of a soul body is its own obsession, and this obsession can absorb those light particle grains, thereby forming the soul body. Those light particle grains are all kinds of positive emotions—in other words, obsession is the skeleton, and positive emotions are the flesh and blood, thus forming the most basic soul body. As for negative emotions, they are more like mutated genes. Once a human soul body is invaded by too many negative emotions, that human soul body will lose its own consciousness, and the body will also undergo changes. Perhaps this is the origin of those legendary vengeful spirits and evil ghosts.)

(As for the lightning rune within my body, it’s more accurate to call it an engine. It absorbs light particle grains and generates lightning, which should be a device that converts the basic energy of light particle grains into a secondary energy source. As for why such a device appeared... it’s probably related to me being burned to a crisp by high-voltage electricity. But no matter what, this might be my only chance for now.)

“Next... is the opportunity to return to the world of the living!”

Chapter Four: Madness and Return to Life

Since Henry Clark’s soul entered this underworld, more than four months have passed, and in this terrifying and hideous hell, Henry Clark is still tenaciously alive... and slowly growing stronger, waiting for the chance to return to the world of the living!

During these four months, in the very first month, Henry Clark figured out how to use the light particle grains. In fact, at this moment, the only way he can use them is to put the light particle grains into the lightning rune, and then rely on the lightning rune to transform them into the power of lightning. Other than that, he really hasn’t found any other way to use them.

But after all, Henry Clark is a conscious human, different from those monsters that act purely on instinct. He has also gradually summarized some of the mysteries within the soul body.

First, a light particle grain about the size of a ping-pong ball is one unit of standard energy. Of course, this standard is one that Henry Clark himself has defined. One unit of standard energy can generate one unit of standard lightning power through the lightning rune. As for the power of one unit of lightning, it’s about half the explosive force of a hand grenade. It takes two units of lightning power to produce the explosive force of a hand grenade. The total amount of lightning power Henry Clark can store in his whole body is about four units. In other words, once he has stored up four units of lightning power, no matter how much he tries to activate the lightning rune, it will not absorb any more energy, nor will it generate any more lightning power. At that point, the lightning power stored in his body is already at full capacity.

The limit of stored lightning power depends on how much energy he has in his body, and the amount of energy he has depends on the strength of his own obsession. Using a ping-pong-ball-sized light particle grain as one unit of standard energy, for every unit of standard energy Henry Clark controls, his obsession is also divided into one standard unit. At this moment, Henry Clark has a total of 127 light particle grains in his body—in other words, he has 127 units of standard obsession. Based on the fact that all the light particle grains in his body can only store four units of standard lightning power, it works out to about every thirty units of standard energy being able to store one unit of lightning power.

This is Henry Clark’s current summary and calculation of himself: he has a total of 127 units of standard obsession, 106 units of standard energy (the rest consumed in lightning power experiments), two sets of lightning runes, and four units of lightning power. This is all he currently possesses. Among all this data, his own obsession is the foundation of everything—it can absorb light particle grains and also form lightning runes. This is the most basic aspect of the soul body.

In fact, after all these days of exploration, Henry Clark has also discovered that his own obsession is not unchanging, but is gradually growing stronger. However, this process is very slow, and each time it only increases when Henry Clark enters a state of tranquility. At that time, Henry Clark is in a state of extreme mental focus, with not a single distracting thought—the purest state. Perhaps only in this state can one generate their own obsession.

According to Henry Clark’s calculations, after accumulating about one hundred hours in a tranquil state, he can generate one unit of his own obsession. Moreover, as his own obsession increases, his ability to enter the tranquil state improves, and the speed at which he generates obsession also increases. Maybe after waiting a few more days, when his own obsession reaches two hundred or more, it will only take a few dozen hours to generate a unit of obsession.

This is the entirety of Henry Clark’s summary over these days, and it is precisely because he discovered the power of lightning that he has been able to survive in this terrifying underworld for four months.

In fact, Henry Clark has already reached the edge of that space rift. He poked his head out and looked down. This was a world far larger than he could have imagined. The space rift was actually a massive, hole-like void, and several kilometers below, there was another layer of continent. Beneath that continent, there was yet another continent. Henry Clark could only vaguely see three layers of continents, and this massive void seemed endless. Who knows how many more layers of continents exist below? At least, from the perspective of the layer of space where Henry Clark was, it was already vast and boundless.
