Li Shen, is someone who is born with the lineages of both Sun and Moon. He worked hard for so many years, explored rifts, dueled countless individuals, fought against the conspirators and replled many ambushes before ascending to Godhood.
He created his own God Position that has potential that can grow into Supreme God King in the least. When he ascended to the god realm he is isolated by Tang San and his family, Tang San who just became a supreme God King Thanks to his grandson Lan Xuanyu's power has the ultimate word in god realm.
He only allows his family and their bemefetors to ascend to divine realm. As a result, he who became a God independently became a target. He wanted to crush this guy during heavenly tribulation but failed as even the legendary 9 coloured tribulation failed to do anything and even got absorbed by him strengthening his foundation.
The greater good circle started to have cracks as Tang San started suppressed the newly ascended gods following Li Shen. Soon in a few years, a conflict broke that shook everyone. In that war, the greater good circle suffered many losses. Whether it's the newly ascended gods, old gods or the god kings everyone paid a price.
The new Dragon God is dead, so is the Asura Goddess, God of destruction and Goddess of life. The core of greater god circle faced the cost. As a result the newly established greater god circle became unstable. A space-time turbulance occured due to the war making the remaining gods to defend the realm.
Taking advantage of this, Li Shen escaped into the Space-Time turbulance. But he who has grasped the powers of space and time, and stripped the positions from the God circle used the divine artifact space-time shuttle he stolen from Tang San along with the positions of God of space and time, managed to return safely in time to the era of Dragon God's failure.
The Dragon God who wanted to ascend the god realm into a high tier failed and split into two by the 5 great god kings. The soul beast race is shackled to never reach godhood in planes that are under God Realm jurisdiction. At this time, when Li Shen recovered from his injuries and used the divine weapons, and resources he had stolen from Tang family, ascended to God Realm again facing the heavenly tribulation.
This time, he had an additional authority with him. Previously he has domains over sun and moon but now he can gain the powers of stars. A concentrated version of sun, just like Light and Holy attributes. His ascension caused quite a stir at that time. The 5 god kings who are already tired from the fight, allowed him to ascend but they're wary of him.
Li Shen didn't directly go to God Realm, he established his sect in every plane he can find by sending his clones there. Only after he felt the flow of large amounts of faith to his throne that he joined the divine realm waiting for Tang San to be reborn in order to get his revenge.
And he also made the clear sky family quite miserable by bestowing some other families with the powers of extreme and ultimate attributes. They're from his sect of course. He added a condition to let them join the sect. Everyone needs to sign a contract to be loyal to him and the sect, they also can't disclose the secrets to any outsiders and those in sect who aren't worthy of it.
So in douluo, before even ascension of Angel God and Sea God. Many Gods are born and ascended to God Realm. In disguise they're nuetral gods, but in reality, they're his subordinates or disciples bound by his oath. With the appearance of these gods many sects are also born that are powerful enough to rival other factions.
His hatred for Tang San also poured into destroying Sea God who is beaten black and Blue publicly along with the leak of his notorious acts in douluo continent significantly reducing his faith and barely making it into a second level god position. Even in divine realm he is isolated by many.
The God Kings though felt something is wrong when they saw the Sea God and investigated but they're cut off when they saw that Sea God tried to get into the faith and domain of Water God. So everyone except Asura God ignored it.
Asura God is very suspicious of Li Shen. When they fought, Asura can feel Li Shen is holding back quite a bit and even then Asura is beaten down in a few moves. This strength terrified him, he don't want the rise of another Dragon God like figure and moreover, Li Shen and Destruction God has the ideas of expanding the divine realm which is the main cause for God realm's situation now as Dragon God executed it and failed.
That's why he isn't on the side of Li Shen who is very noble on the outside and very cunning in the inside. Asura also knew some newly ascended gods from different planes under the God realm are Li Shen's lackeys. But he has no proof of that.
By now, in the God Realm, there are 28 first Gods. Half of which, he suspected to be from Li Shen's faction acting in secret. But he didn't exactly know who are they? And worse many of these first level gods have the potential to reach God King realm. Asura can't bear to see this God realm becoming someone's property, but he is also tired staying in the god realm. He wanted to explore the universe by leaving this god realm. So he planned to bring a soul to douluo continent that he likes and can inherit the Asura God throne.
