The First 10th Rank Open Heaven

~~Inside Lei Jin's Inner Domain~~

"About 500 years has passed since Yang Kai said those words. At least according to the outside world anyways. In here… multiple more thousands of years have passed. The people I brought out last time have reached the Open Heaven Realm already and begun their training." Lei Jin murmured to himself. "I have started pushing more towards finishing my fourth World Array. The third one completed not too long ago. Seems like Ruo Xi was right. With the power I can wield now. Creating new worlds is easier than before. And the three complete World Arrays have created an interconnected array for themselves as well. My power flows seamlessly. I'm confident that even if this was all I could manage to build up to. It would be enough to ensure victory." He added. 

"Master, The strength you have now is simply breathtaking. And gives us disciples a level to look forward to." The Eldest Disciple said, bowing respectfully. "Without Master, we would not have what we do today…" She continued. 

Lei Jin looked at all of his disciples among all of the generations. With each new detached generation of disciples they bowed in progressively deeper manners. Showing the compounded admiration and respect. "You're acting as if I'm leaving for good? I'm not dead. And nor will I be." Lei Jin smiled. "I have responsibilities to the outside world. And they can not be ignored. While I may seem different now… It is because I am happy I don't have to bring any of you out to fight the enemy. You living here and managing the growth of the people and keeping peace and order, is the best thing." He added. Pulling his four disciples into his arms for a big hug. 

"Master, you'll embarrass us in front of our children and our disciples." The second Disciple stammered. 

"Don't worry, I'm sure they are just a little jealous. They will all get their turn." Lei Jin said, and then did the same for everyone of the disciples among the generations. And then he let out a soft smile. "I don't want any of you to worry. I may not reappear for a while. But I will leave a soul clone behind that retains my judgment and wisdom. So there will not be a moment you won't be able to ask anything. It's the least I could do. After all, I am where I am today because all of you helped me in this endeavor. Live well and train hard. I want to see you all grow up strong and healthy." He said, vanishing as a soul clone formed in the spot he had just occupied. 

~~Outside Lei Jin's Inner Domain~~

"Now that I have reached this point I am convinced that I can defeat the Ink Clan's Progenitor. In fact I might even be able to create a rainbow clan if I tried hard enough. But I'd prefer not to go down that rabbit hole like Ink did. The True Rainbows are enough. And while it does put the human race at risk of death. It is better than being protected by another race. Especially one created in a similar fashion to the Ink Clan." Lei Jin thought. "Anyways, it seems like Yang kai is about to make a breakthrough. I should go and see it." He continued. 

~~The Gathering Of 9th Ranks~~

"Yang Kai wasn't wrong. That was indeed how to breach to the next rank. But why does it feel like something is still missing?" Liang Changming said. 

"I'll take a look." Lei Jin said, appearing out of thin air. He then inspected Yang Kai's condition. "So that's the method you chose. Not a bad plan. Though it will take you some time." He said. 

"Brother Lei Jin, will my husband be alright?" Shang Qing Luo asked, worriedly. 

"Ahahaha, don't worry, even if he fails to breakthrough, I can save his life. But if you look closely Yang Kai is not in any danger. It's just going to be a while before he is finished. That said, there is a way to make it go faster. But you and your sisters will have to work together." Lei Jin said. 

The other 8 wives appeared quickly. "What do we have to do?" Su Yan asked. 

"Simple, form a 9 directions array with each other and feed into him. It won't cause him any harm. And I know you can pull it off. After all, you all cultivate the same dual cultivation method I do. So give it a try." Lei Jin explained. 

The 9 wives didn't miss a beat and performed the Nine Directions Array nearly effortlessly. But it wasn't your average one either. Each of Yang Kai's wives formed a link with all of the others. Imitating the world array inside an Inner Domain. And then linked up with Yang Kai. That moment was silent. All of the 9th ranks were excited and nervous. 

"Yang Kai, remember that one must anchor themselves and also not at the same time. Only then will they have the qualifications to earn the support of many worlds." Lei Jin whispered to Yang Kai. 

The other 9th ranks would likely lose their minds if they heard these seemingly inconsequential statements. However, to Yang Kai, the words were nothing short of the largest possible boon. Yang Kai's wives working together was only an attempt made to make it look effective. Either way, Yang Kai's energy soared to new heights. Quickly reaching the limit of what peak 8th ranks could scarcely differentiate. Becoming seemingly infinite in the process. 

As for the 9th ranks… They sensed how strong Yang Kai was becoming for far longer. Yet still, his power surpassed the limit they could understand as well. It was after this that Yang Kai opened his eyes. "My wives, you can stop now. I have finished. I only need to consolidate my new realm. Thank you for always having my back. I love you." He said.

A short time later, Yang Kai stretched and looked at his hands like he had done many times before. Looked up and smiled. "I'll take care of helping others along this path. I now have a far better understanding of this level." He said, making a gentle fist. And a wave of pressure filled the air as a result.
