The Deities were afraid that the Demons would attack them again if they didn't finish them for once and all.

But the Heaven Emperor was still a little bit reluctant to kill his son even after his act of backstabbing and treason against the Heaven Realm.

Deep down in his heart, the Heaven Emperor had always regretted snatching away his son's mother just a few minutes after his birth.

He didn't like how the little boy was confined in the four walls of his chamber from day one, deprived of any kind of love, affection, respect, warmth, or resources, all the things that a child and a Prince deserved.

But he couldn't deny the truth that if they had provided him with all those things then they would surely have to pay a much bigger price then what was happening at that time.

Moreover, even if he ordered to kill every single demon along with his demon son, it wasn't like the Deities were able to kill even a single one of them. And the worst part was - they were unable to find out exactly why?

But there was a person there who was aware of what was going on. About why the demons had suddenly become impossible to kill.

But his guilt was now stopping him from killing his son. He had no idea at that time that the world would pay a very big price just because of his hesitancy.

After months of planning, they finally came across a solution. Just like how they created a realm for mortals, once again they created another realm for demons.

The Demon Prince and his followers were sent to the newly formed realm which was known as the Demon Realm. A place which had a limited source of water, very small forests, very little wildlife, and next to no spiritual qi. Most of the realm was covered with huge rocky mountains and deserts. It was capable of feeding the demons and keeping them alive, but just barely.

For the next few thousand years, the Demons stayed under the radar. Making no movements or at least that's what the Deities assumed.

As time passed and the Deities confirmed that the Demons had given up, they started paying less and less attention to the Demon Realm.

They had no care in the world if the Demons were alive or not as long as they stayed inside their Demon Realm and left the other two realms alone.

The Demon Prince had learned to teleport between the realms a long back ago. He used to teleport to the Mortal realm when he needed something to buy.

Therefore as soon as his powers were back to their peak, he teleported into the Mortal realm, a place which had become his favorite during his time in the Heaven realm.

The Mortal Realm provided the Demons all the things that they needed and the most important of them was the weapons. The Demons had turned the Demon Realm at least into a habitable place. They even started growing their own crops because looting food from the Mortal realm would have grabbed the unwanted attention of the Deities.

They were so silent and clean in their movements that the Heaven realm never realized that another attack was going to greet them in the near future.

But they had learned their lesson last time. The Heaven Realm had a much stronger and bigger army than before.

The next war also ended with only losses on both sides. But the Demons were not ready to back down any time soon.

Their animosity towards the Heaven Realm and the Deities only increased with the passage of time.

When the Demon Prince got married to a mortal and had his son, he taught him to be as ruthless and merciless as himself.

The new Demon Prince also had only one mission, conquer the Heaven Realm and snatch away everything that was supposed to be theirs in the first place.

As millennium passed new rulers appeared in both Heaven and Demon realm but nothing changed.

Every new ruler of Demons wanted to conquer the Heaven Realm and Every new ruler of Heaven Realm was trying to find a way to completely finish off the demon race.

And in the middle of the animosity of these two realms, the mortal realm had become a constant target of the Demon Realm to irk the Deities.

But in such a long time, the demons had grown both in numbers and power. Though they hadn't surpassed the Deities and Heaven Realm in power and strength but they were not too far from reaching there.

Finally, the time approached when for the first time in millenniums, two demon princes were born.

Both had a very cold, terrifying, and powerful aura from the moment of their birth. Just at the age of ten both the Princes had surpassed all those demonic cultivators who were in their thirties and had been cultivating for decades.

The Demon Emperor was joyous beyond imagination. He could finally see the Heaven Realm crumbling and bowing at the feet of his sons.

The Heaven Realm was also aware of the high achievements of the two demon princes. Though the Crown Prince of Heaven Realm who was barely a few weeks older than the two demon princes was also surpassing all his seniors in cultivation and was as powerful as the two demon princes, but the real problem arose when a prophecy was made.

Only the Diviner God, The Heaven Emperor, The Heaven Empress, and two more deities were aware of the prophecy. It was made sure that these words never reached the ear of a sixth person.

Exactly a month after the prophecy was made, the Heaven Realm sent an offer for the two Demon Princes to join the Heaven Disciples Academy.

The Deities were sure that the Demon Emperor would never send his barely ten-year-old sons to the Heaven realm, no matter what. But to their surprise, the two Demon Princes were standing in the Grand Hall of Heaven Imperial Palace, the very next day.

Just like the Heaven Emperor had his reason behind inviting the demon princes into the Heaven realm, similarly, the Demon Emperor had formed a plan of his own before sending his sons to the realm of Deities.

The two Demon Princes remained in the Heaven Realm for nearly about ten thousand years. Their close group of friends had become their only family.

Finally, the two Demon Princes passed the Academy along with their friends and were ready to return to their home realm.

The day these two princes finally returned to their realm, a storm hit the two realms which swept away everything with it.

The Heaven Emperor punished the Crown Prince because he failed in his mission of killing the two demon princes. Not only that but he had also formed a brotherhood with them.

The Heaven Emperor sent him away for closed-door underwater cultivation and maybe this was the exact decision for why the Heaven Realm went through such a dark period in the coming five years.

While the Crown Prince of Heaven Realm was in closed-door cultivation, the Demon Emperor too had lost his mind in rage.

Both of his sons made it clear that they had no interest in the Heaven Realm and ruling it. Rather than destroying the Heaven Realm from inside in these past ten thousand years just like the plan was, they completely ignored it.

The Demon Emperor decided to brainwash his sons just like his father had done to him when he was a child but nothing worked on the two princes. Though they never took the side of the Heaven Realm but they also made it clear that they were not going to participate in any war.

Their only plan for the future was to create a Demon Realm which was even more beautiful and magnificent than the Heaven Realm.

In his anger, the Demon Emperor divided the Demon Realm into two provinces - North and South and appointed each of his sons as the head of one of the provinces.

He wanted to see exactly how they were going to convert the barren and dark Demon Realm into a place like Heaven Realm.

Both the Princes tried their best and gradually things started changing in the Demon Realm but this only infuriated the Demon Emperor and just like that in his rage he attacked the Heaven Realm.

By the time war came to an end, the Demon Realm had lost their Emperor but while killing the Demon Emperor the Heaven Emperor had also injured himself very badly which led him into a deep slumber.

The two Demon Princes finally made a peace treaty with the Heaven Realm. The two realms had faced so many blood baths and loss during their millennium-long animosity, it was finally the time to stop the pain and darkness that came along with war.

But unknown to everyone, even a much bigger conspiracy was going to strike them soon!
