Yang Rai continued his cultivation, taking a break every 5 years to check the status of his trees. He gave up hope that the Rank 8 tree spirits would be vastly different from each other. As every single one of them tried to one up the other sisters on how much they can beautify themselves. Yang Rai knew that there was no stopping that ship. It had set sail long ago. Instead he used this to help him further temper his mind. After 500 years of total time inside the chamber the lesser world trees produced some fruits. It took them some time but Yang Rai was thankful they even did anything at all.
When Yang Rai harvested the fruit he noticed that each low rank fruit from these trees was actually far weaker than the world fruit from the other main tree. It wasn't a bother since he was just surprised it even worked. When he inspected each fruit they seemed to have the abilities of a StarFields. He decided to dub them Field Fruits. A further distinction would be made by analyzing the strength of the StarField itself. He harvested them all making the decision to return the world fruits he had received as he no longer needed them anymore. Not after what he found out what would happen to the world they were connected to.
Yang Rai continued his cultivation all the way up until his daughter's 15th birthday. Both of them would be making their way there now. Overall Yang Rai was quite pleased with himself so far. He could sense that many of the Dao seal realms in his Artifact were recovered and could come out any time. However they didn't want to leave just yet. The crazy strength of the Artifact world really helped them with their base. So Yang Rai left them there.
He was more proud of the now 81 rank 8 trees. Though he could have been happier if they hadn't all formed their spirits into partially naked women. The final tree decided to cover herself with hair. When she ran around You could see everything. He had to keep other men out of the garden at all costs. Aside from that he could now generate whole StarFields. Though that process is terribly slow. It is a major help since they can give him new sources of which to create and absorb more little world spirits. One final thing was he managed to increase the flow of time by an additional 10 years. It was now 80 years inside to 1 year outside.
It was time. Yang Rai left his Seclusion and appeared behind his two little girls. Surprising them when he hugged them.
"Happy birthday girls. I can't wait to see how much you've grown."
"Father! You did come and see us."
"Yay, Father did come."
"Of course I'll come to see my little girls. I even brought gifts for you."
"Really?"x2
Their eyes were sparkling as if to say 'Well what are you waiting for' He absolutely adored that face. After a big hug he decided he was going to see how well they were trained. A sort of mock battle for them where they could go all out. If it was against Yang Rai not a single soul could hurt him. He was the perfect person to see their true strength. He had an idea.
