Reincarnated as an Energy with a System

Reincarnation Cycle. The cycle which kept a human continuously coming back to life in a new body was something Ning knew was a thing for a long time and had even made use of it to find Hyesi.

There were many things he didn't know about it, however, and only now was he figuring them out.

"A soul leaves the Realm of Matter, which is our universe, and goes out to the Realm of Soul," Ning repeated what the system said. "Then it comes back. I think I understand a little."

He thought about what he had heard about the reincarnation cycles throughout his life and it made sense based on what he had heard for now.

But… there were a few more questions regarding the cycle he now wanted to know about. That was without mentioning the questions that had formed that he hadn't even gone toward.

"Ignoring the other questions I have for now, I want to know about exactly two different things," Ning said. "First, why does a soul forget memories? And what does a system help them remember through the reincarnation cycle?"

Those were the two main questions he wanted to learn about before any other questions were answered.

The system didn't answer for a second, making Ning think he had asked something he shouldn't have. Something forbidden. 

However, the system answered a moment later, but not the answer he was expecting.

<To understand the answer to those questions, you will need to know of another piece of information that you learned just yet>

"Hmm?" Ning got concerned. "What else is there for me to learn?"

<There are 3 different parts in the puzzle of life, and you have only learned about two. Energy and Souls.>

Ning's eyes widened slightly. "There's more?" he asked. What more could there be other than Energy and Soul? "Is it Matter?" he asked.

<It is not Matter. The third part of this puzzle is Consciousness or better known as Intelligence>

<Where there is Energy and Soul, there is Intelligence. They are the triangle of Existence itself. Two cannot exist properly without the third.>

<Souls are existences formed from pure Energy and they have Intelligence>

<Place enough Energy in a place and it forms its own intelligence, creating a sort of soul, that is commonly known as a spirit.>

<Have just a Soul with Intelligence and it will learn to siphon off Energy of its use, either drawing from the surrounding or from itself.>

<That is the Triangle of Existence, the three pieces of puzzles that form life.>

<They cannot exist without each other>

Ning's eyes went wide in shock when he heard that. He placed his chin onto his hands, leaning to try and process what he heard.

"Energy, Soul, and Intelligence," Ning repeated to himself. "One cannot exist without the other two. What if you take away one somehow?"

<If the other two aspects as strong enough, they will create a new one. If they are not, they will cease to exist.>

"Can you give, umm… some examples?" he asked.

<As you wish.>

<The first example is none other than Death itself>

Ning's posture got straighter when he heard the words. "Death?" he asked. "What are the three parts to death? I know Soul is there, and there is intelligence of course, but… where is the Energy coming from here? The Soul?"

<Matter>

<Matter itself is energy. So is time. So is space.>

<Anything and every in the Realm of Matter is formed from Energy. So they all count for Energy>

"Woah!" Ning thought."Go on."

<A human has all 3 aspects of the Triangle of Existence. They have Energy in their body, they have high Intelligence from their evolved brain and a soul that got into it, during the moments of the body's creation.>

<When a human is said to be killed, they do not receive damage to their Energy or Soul, but their Intelligence. Due to the damage to their body, their Intelligence  or Consciousness is destroyed.>

<At that time, Triangle is broken and the connection between the Energy and the Soul is terminated. The soul leaves the body, making its way back to the Realm of Souls.>

<The Energy disintegrates into other forms to move on as well.>

<That is how death works. Destruction of the Triangle of Existence, defeating life itself.>

"I see," Ning said. "So that's how death works." He had never truly thought about it enough to question how it worked, but there had been a thought in the back of his mind as to why exactly a soul left a body when the body was harmed.

Now he understood that it was because of the Triangle. Because the Intelligence in a human was destroyed, the Soul was no longer tethered to that body.

"So… if we can somehow introduce intelligence to a dead body, can the Soul move back?" Ning asked.

<That is impossible>

"Why?" Ning asked. "That makes perfect sense."

<Because there is already another spirit forming in that body>

Ning paused. "What?" he asked.

<In the absence of the soul, the body forms another spirit with its own intelligence, completing the Triangle.>

"That doesn't make any—"

<However, this spirit is way too weak to sustain itself and the intelligence is no different from that of a rock. So, it quickly dies as it does with all forms of spirits>

<That alone, however, is enough to not be a place where a soul would want to stay. As a result, it very quickly leaves for the Realm of Soul.>

<A Soul rarely lasts in the Realm of Matter more than a few seconds, except under very rare circumstances where it finds another body to go to. That is very rare as most other souls would already have entered the Realm of Matter by then in search of new bodies.>

Ning heard the explanation, thought about it, and immediately had his mind blown once again as he gave thought to the System's words that were just in passing.

"Wait a minute," Ning said as the information about spirits in his mind gave him the information he was looking for.

"Holy shit!" he couldn't help but say when he found it out. "Every single matter in the universe has a spirit?"
