The first Law Gravis comprehended was also the very key to all the other Laws that would follow.
It was the level four Law of Microorganisms, also called the Major Law of Life Energy.
Back in the middle world, Gravis had comprehended the level one Law of Microorganisms after comprehending all the level one Composition Laws of the Body and Plants.
This level one Law had been the key that bound all the different concepts together, allowing Gravis to comprehend the level two Laws of Body and Plant Composition back in the middle world.
Life Energy was very different when it came to Immortal Cultivation, and the biggest difference was the inclusion of a soul. The soul in the microorganisms allowed the inherent soul-energy inside the body to also regrow.
After Gravis comprehended the Major Law of Life Energy, all the concepts regarding the Composition of an Immortal body clicked into place.
Gravis had learned a lot about the Composition of Immortal bodies due to his time cultivating together with Stella and due to Mortis' experiments on a ton of Immortals. Gravis had also taken some time to comprehend the Body Composition Laws when he was waiting for something.. For example, when Gravis was waiting for Siral's tribulation or in the years when he was waiting for the tournament in the Nine Elements Sect.
All of these insights clicked together to create the Major Composition Law of Organs.
Yet, that wasn't all.
Gravis had insights into all parts of the body, and the breakthrough in Life Energy and Organs had allowed him to connect the other concepts too.
So, in an instant, Gravis comprehended all five level four Laws of Body Composition!
In just a tiny moment, Gravis had comprehended six level four Laws.
However, this still wasn't the end!
Life Energy was what tied everything together.
The level five Composition Law of the Body was simply the five level four Composition Laws of the Body combined with the Major Law of Life Energy.
Therefore, Gravis didn't only comprehend the individual Body Composition Laws but also the overarching level five Law of Body Composition.
Gravis had comprehended six level four Laws and one level five Law.
Yet, that still wasn't the end!
Life Energy was also the key to regrowing a body.
The level five Law of Body Growth, just like the level five Law of Body Composition, required the subsidiary level four Laws and the Major Law of Life Energy.
Gravis already knew the five individual level four Laws of Body Growth, and he had just comprehended the level four Law of Life Energy.
So, all of his insights combined into the level five Law of Body Growth!
In one instant, Gravis comprehended six level four Laws and two level five Laws!
Gravis' eyes widened in shock as he realized how much he had learned due to only a single realization. So many concepts clicked into place all at once, all thanks to the Major Law of Life Energy.
Gravis closed his eyes and took a deep breath as he went through all the understanding he had just gained. So many things made sense now!
Now, Gravis also knew the fundamental difference between a normal body and an Immortal Body.
Everything had to do with the difference in Life Energy!
'So, that's the difference,' Gravis thought as he smiled warmly. 'I finally get it!'
BOOOOM!
Gravis' mind seemingly exploded as he comprehended one last Law, and this one was a big one.
The level three Law of Life Composition, the level three Law of Life Growth, the level three Law of the Soul, and the level three Law of Energy Healing all combined together.
In Gravis' mind, all these Laws became connected in a single, logical pattern that made perfect sense.
The Law of Energy Healing converted Energy into Life Energy.
This Life Energy then fused together according to the concepts behind the Law of Life Composition.
The new object then required a soul, and that soul would be created by using the Law of Energy Healing to convert Energy into Life Energy and then into a soul according to the concepts behind the level three Law of the Soul.
Lastly, the level three Law of Life Growth allowed everything to flourish and grow.
Gravis knew how to create life!
Gravis had comprehended the level four Law of Life!
'The Law of Life!' Gravis thought with shock. 'One of the four major Laws! The Law of Life is at the same level as the Law of the Dead World!'
Gravis' mind fell into chaos for several seconds as ideas sprung into his head.
'So, couldn't I just…'
Gravis thought about a dead world. He used all his knowledge from the Law of the Dead World to imagine this world.
Then, Gravis imagined Energy appearing in the world.
Lastly, Gravis imagined how he could convert all that Energy into life.
The dead world suddenly got filled with grass and trees.
There were even some insects and microorganisms flying around in the air and swimming in the water.
The dead world was suddenly filled with beautiful life.
It was no longer a dead world.
It was now a living world!
BOOOM!
In Gravis' mind, a grey, lifeless ball fused with a green sphere of light, creating a beautiful green and blue planet.
The Law of the Dead World had combined with the Law of Life to create the Law of the Living World!
The Law of the Living World was still a level four Law, but it was far more powerful than either one of its components.
Gravis' mind was filled with ideas all of a sudden.
After that, Gravis looked at his right claw.
'I can create weaker life forms now, right?' Gravis thought unsurely.
In an instant, Gravis had unlocked something that everyone dreamed of.
Gravis had learned the ability to create new life.
Yet, Gravis only felt pressure on his shoulders.
Creating life wasn't something as simple as creating materials. By creating new life, Gravis would either need to kill this life afterward or send it out into the world.
This was a heavy responsibility.
Should he even attempt something like that?
'Yet, I don't feel like it's such a big deal,' Gravis thought. 'I can create something, which doesn't make it really special. I can create and destroy without a problem.'
Gravis got reminded of the words of the Black Magnate.
"I know how everything works! I know what everyone thinks at any given time and what they will do for the rest of their life! I can't lose anything since I can just recreate it in an instant!"
"Everything is worthless, and only emptiness remains!"
The Black Magnate had said something like this.
Now that Gravis had the power to create any weaker form of life, he realized that the Black Magnate had been right.
Gravis knew that life shouldn't be created easily, but at the same time, it didn't feel like such a big deal.
So what?
Gravis took a deep breath as he analyzed if thinking like this was good or bad.
In the end, he decided to postpone all of his thoughts and concentrated on comprehending the Major Law of Strength.
After he comprehended that Law, Gravis would talk with someone that should have gone through these same thoughts.
Gravis comprehended the Major Law of Strength after only a hundred more years, making it a total of 200 years.
This was very fast for a level four Law, and that speed was mainly due to the enlightenment Gravis had gotten from the other Laws of Life he had comprehended.
After comprehending the Major Law of Strength, Gravis left the clearing and broke Arc's token.
Arc should have gone through similar thoughts in the past.
