Summary 1 - Prequel
{I will start explaining the DD2.5 timeline with a brief summary as I didn't think much about it.}
DD2.5 timeline
God Kings:
Hui Mie (Destruction God)
Xie Lingling (Life Goddess)
Tang San (Sea God)
Qian Renxue (Angel Goddess)
Ji Dong (Evil God)
Lie Yan (Goodness Goddess)
Like the original Hui Mie decided to take control of the Divine Realm to expand it. This time taking advantage of Renxue's and Xiao Wu's pregnancy and Ning Bai close cultivation and absence as due to his sword from Asura, he is able to damage even God Kings as a first rank god.
Bibi Dong, Yu Xiaogang, Fenrir and Mayi helps Hui Mie facing against the other ghost and capturing the pregnant, making Lingling and Tang San give him the control.
In the end similar like in the story, Xiao Wu gave birth to Tang Wulin and Renxue to Xueqin. Hui Mie sacrificing with Sheng Ming who recovers her Life Goddess position for Lingling to nor sacrifice to keep the realm. The Golden Dragon God is released. However, this time they are unable to cope with it lacking Asura. In the end, Bai appears, having to break through the God-King realm and easily cutting the Golden Dragon God.
In the last struggle, the Golden Dragon God throws his core to kill at least someone. Bai cut over the core, dividing in two, but they didn't stop, fusing with one half with Tang Wulin and the other with Xueqin. Wulin's core is mostly the strength of the dragon while Xueqin is the anger of it.
Bai uses his own sword, his divine weapon to seal the Golden Dragon in Xueqin's mind space. Renxue gave him her halo, boosting his mental defense to be able to cope with the Golden Dragon's anger and Ning Maya gives to his brother a type artifact that she was working in it, but it would only be useful if he would awaken a spirit related with the Nine Colored Pagoda.
Tang Wulin is exactly the same and both are send to the douluo continent to keep them absorbing divine energy.

{The next are facts that would have been informed later over the story, but I didn't really know when exactly explain each one.}
Sword Valley:
The Sword Valley is in truth a Divine Realm created by Ning Bai. Even with the Divine Realm disappearance, people can reach godhood reaching the peak there.
To become a god some requirements are needed to be met.
1- Be a monarch: Needing to reach the All Sword Realm and pass the test of the 6 Sword Souls that were the previous core of the God Sword from the other novel, with the exception of the Asura Sword. Bai let them over there, considering them useless for his own strength and will rather be more fruitful there. A Monarch acquires a pseudo 10th spirit ring. This pseudo 10th ring let him use peak of the sword, the Divine Soul Sword, without any lose inside the Sword Valley. Outside of the Sword Valley, they can only use it one time, then losing it and losing the qualifications of a monarch forever.
2- Becoming the Sword Douluo: Win over the Sword Douluo Festival or directly killing the Sword Douluo having reach the All Sword Realm. In the case, there's no Sword Douluo, the Sword Douluo Festival, changes, the Sword Souls becoming the host to decided how the next Sword Douluo would be decided.
3- Passing the Sword God Bai's test: Fighting against Bai's own projection. Only Sword Arts are permitted to be used and Bai would only use the same intent as the rival, meaning to surpass him in one intent. This made it extremely difficult to Life and Death Sword God to appear as Bai was the strongest with them. Aria the current Sword Douluo unable to win against him.
