After his youngest four finished the refinement process for their new small sealed StarField beads Yang Rai spoke with his eldest daughters. He wanted them to try something. So he prepared several low rank StarField fruits for each of them. He figured they should be able to handle this since they were both 2nd order emperors now.
"Mo Xun, Lan Qi. I have resources for you as well."
"Thank you father."
He handed over dozens of the fruits to each of them along with a copy of the technique required to fuse the StarFields within the fruits directly. This time he wouldn't teach them how to do this directly but would give them guidance should they find the need for it. All of this so he could speak with his wives about the situation.
"Husband, come and meet these wonderful women."
"I see, You've brought along 16 others with you this time. Greetings, I am Yang Rai, this World's Master and Vice-Palace Master of High Heaven Palace."
"Madam Lan Xun, you said he was handsome and talented. You didn't tell us that he would be this Handsome nor this talented."
"I don't deserve to keep him to myself."
"That's never been true. The depths of my love for you can rend the heavens and change fates."
"He also knows how to treat a woman. I've decided. Even if I'm only 1 of your many numerous wives or even mistresses I wouldn't want to have another man as my husband."
"I believe this wholeheartedly."
"I couldn't think of a better man."
"I wouldn't want to intrude, but since your current Wives are allowing it I would like to be with you as well."
"I can't think of a better husband. I would be honored if you took me as one of your wives."
"Husband, please. Won't you accept them?"
"Seems like I'm going to be very busy. Very well then. I'll accept all of you, my wives determined there is enough of me to go around. Besides, I'm a man. With you offering yourselves to me like this I couldn't simply refuse. You all have the qualifications to become one of my wives. This one here will partake."
Shortly after, Yang Rai had vowed to accept the 16 new women that came along. All were Great Emperors of the World within his artifact. Considering just how many Great Emperors he supported in his Artifact 16 hardly registered as a droplet of water in the vast ocean. Well over 1000 Great emperors could be supported by his Universe world. His current children had finished their tasks then reported their experiences.
After this Yang Rai let them back into the Cultivation Spring so they could advance more and become stronger. His two eldest daughters were tasked with helping his youngest four. However if they have any questions at all do not hesitate to ask for advice. Yang Rai was going to be extremely busy. He and his now 20 wives began their 'endurance competition' . This time it went on for 100 days before all 20 were passed out from sheer pleasure.
