Back when Shi Yu created the two realms, he created a unique power system for both of them. Each realm was different and unique in the fact that each went a different path but return to the same point.
It was like a how a tree has many branches that grows in different directions but at the end of the day, share the same root.
In the Heavenly Realm that is model after the heavenly dao of the immortal realm, there were creatures created solely to serve and protect the realm from harm.
These beings are called Heavenly Warriors. The Nether Realm has Nether Warriors.
To make a good analogy, the Heavenly Realm was the host and the Heavenly Warriors were parasite that relies on one another to survive. However in this situation, the Heavenly Realm had more power over the parasite that is the Heavenly Warrior.
Heavenly Warrior is what one calls, the servants of the Heavenly Realm. The Heavenly Warriors consist of Heavenly Soldier, Heavenly Commander, Heavenly General, Heavenly Lord , Heavenly King, Heavenly Emperor and Heavenly God.
Similar classification of realms was use for the Nether Realm as well, however while Heavenly Warriors enforce the rules of the Heavenly Realm, the Nether Warriors protect the balance between life and death.
Each stage was more difficult to reach than the last. In fact, when he created the Heavenly Realm, Shi Yu had never seen a being above Heavenly General since to advance beyond that level, one must become a God. And since every piece of land in the immortal realm was monopolize, it was very hard for even the weakest level of gods to appear.
This was also the why the immortal realm as called the immortal realm instead of god realm. It was because immortals were more common and more powerful than a god in direct combat, that gods were not seen as much in the eyes of mortals, well, in the immortal realm anyway.

Digesting the memories of the former Shi Yu, and confirmed his previous guess, he was indeed not a normal person. He was once a proud member of a Noble faction inside the kingdom, the Shi Clan, however because of his fathers action, the glories of his family became a curse that followed him everywhere seeming to have the intention to devour him whole.
Because of this reason, Shi Yu was not stupid enough to return back home without having enough strength to protect his life. To do that, Shi Yu would have to clear one of his block meridian.
Shi Yu knew that his limit according to his innate talent of this body will be the limit of body refining, which was already consider a blessing. If he was a ordinary immortal, that would be the case, even if he had no talent at all, he was fine, as he could always change to this worlds cultivation system, which seem quite interesting in his opinion.
This system which is call Bloodline Cultivation System only had four realms or levels, the first being Blood Infusion Realm, the second Partial Beast, third Beast Blood, and the last Complete Beast.
The Bloodline Cultivation System don't have sub levels, since the levels are just a vague concept that was created by much research done by the people of this world. Shi Yu could see many ways he could improve upon this system, but was there really a need?
Firstly, he was obviously going to re-cultivate the immortal path which he was supreme at. Secondly, with his two realms, even if didn't cultivate, it was very difficult for him to die from old age, as he was living according to the rules of his two realms and not the rules of this universe.

~Two Months Later~
Deep inside the forbidden forest, so deep inside of it, a place barely any humans had venture into before, two figures could be seen fighting, leaving behind after shadows.
The ground shook as trees broke apart as if strings snapping from being pull too far apart.
Boom! Boom!
The ground was full with fist imprints, with some have a very deep depths.
All of a sudden the two figures distance themselves from each other, both breathing deeply, as bruise and blood dye their figures.
One of the figures was a human that had long hair reaching down his back, standing at a height of 2.5 meters. The aura around the figure was heavy and dark like as if a storm was brewing.
This figure was obviously Shi Yu, who has stay in the Red Forest for training purposes.
His opponent was a huge three meter tall brown ape with a golden hue to its fur, making it look a bit divine. The ape was standing tall and look at Shi Yu severely as it pats its chest with its hands, causing a clank clank sound, as if metal was hitting metal.
On the apes fur one could see some golden blood that flow through some small wounds on it body, which were like mosquito bites to it.
The ape beat its chest hard and growl before shooting off at lightning speed, appearing in front of Shi Yu as if teleportation.
Shi Yu frowned and side step to his right, and bend his knees, dogging a violently swipe that was intended for his upper body. Also, even though he side step, Shi Yu, grimace as he held his side with one hand, as he felt a couple of ribs crack.
Just the wind pressure from the strike was so powerful! If that attack had landed, he would have die!
Shi Yu force the power from his opened meridian , increasing his power by two times, increasing his power and activating the Life Bug unique feature of healing.
The ape, seemingly confuse as to why it's attack missed its mark, stop and scratch its head. The ape look at its freed opened hand and close it, and then look at Shi Yu before looking back and forth, before deciding to attack again.
Seeing the ape about to attack again, Shi Yu lips twitch, " Wise Ape, that's enough practice for today."
The ape although disappointed that practice was finished, the ape walk over in two legs like a human, while rubbing his chin thoughtfully. It's expression was deep and profound as if it had solve the ultimate question of life.
Shi Yu and Wise Ape walk in silence as each was lost in their own world.
Shi Yu was thinking of how amazing this demonic ape was. Even though he was in his normal form, it was able to beat him, mind you he was restraining his full potential as with his current power and his experience as a immortal, he had many ways to kill the ape, even though it was at the peak of Rank 1.
Demonic beast were separated into twelve levels. The first the weakest was rank 1 to the strongest rank of 12.
The first rank is akin to Body Refining Realm of immortal realm. And the last rank would be equivalent to Void Immortal realm if not stronger.
So that means this ape was a threat to Stone kingdom according to his current memory. For him to be walking around calming with this ape was obviously because he conquer it.
That's right, in the first month of being inside the Ref Forest, he had chance upon a spiritual herb, making him relive that their were indeed spiritual herbs in this world. However what made him confuse was were was the spiritual energy?
From his knowledge, almost all herbs back in the immortal world use spiritual energy if not immortal energy to grow, which was why this situation was odd.
Shi Tu solve this problem by using his immortal sense to look at the roots of the herb, seeing many white bones buried at the roots of the herb.
So instead of absorbing the energy of heaven and earth, this herb evolve in a different route to suit its environment or better yet, that's just how it was design from the beginning.
Around the herb, there was a guardian watching it, living a true symbolic relationship together. it would receive nectar that increase its strength and In return, it would provide protection to the herb.
The gaurdain was Wise Ape who seem to have his intelligence increase to the point that he was almost on the level of mankind. In fact, as long as he reach Heavenly Commander stage, it would become a race like mankind, able to further awaken its intelligence, surpassing humans in the process.
After meeting Wise Ape, Shi Yu went into the Heavenly State, defeating the ape in a instant, and was about to kill it, when he saw the flames of intelligence inside its eyes.
The flames of intelligence was extremely bright making Shi Yu amazed and decide to grant it a chance and turn it into his first Heavenly Warrior.
Although it was a Heavenly Soldier, by becoming a member of the Heavenly Realm, it recieve the blessing of the heavenly realm, and a massive boost to its already strong power. But just like him, it was only able use the aura of the Heavenly Realm for a moment before it needs to recharge.
Siting inside a cave with a fire burning brightly, Shi Yu and Wise Ape ate a roasted deer, devouring it, not even leaving behind the bones.
Shi Yu look into the skies and he's wipe his mouth and observe the celestial bodies. He had been doing this, ever since he came to this world.
He was seeing and monitoring the changes of the heavens of this world, which would help when he make his realms occupied their position and take control over this universe, before returning and battling that Void Immortal!
