"I'd rather not exchange them for a whole set."
"What should we do then?"
"Can we set up a quest instead that anyone is allowed to take. I'd offer 9 full sets of 9 5th rank materials upon completion. The task will be to collect a star field and deliver it to me."
"Collecting a whole star field may be difficult. Do you have a means of collection?"
"Yes, those who take the quest will be issued an artifact similar to the small sealed world bead. I can create them quite fast. And they only take a set of 3rd rank materials."
"Yang Rai, You're still an emperor. Is there a reason you have yet to condense your dao seal?"
"Ah, about that. Come into my Knowledge Sea. You'll figure it out quickly."
Yang Rai had them enter his Knowledge Sea which they saw was massive. Not only massive but also full of incredibly dense and pure energy. It was nothing like a normal cultivator's Knowledge Sea.
"This is… How… What?"
"Yang Kai, how is your brother this strong? His knowledge sea is larger than a 4th Rank OH's Universe."
"Your guess is likely as good as mine."
"Alright everyone. What you're about to see is one of my greatest secrets. It is sadly the only way to explain my issue of condensing a Dao Seal."
81 Origin Essence Crystals appeared. They were incredibly dense in nature. The energy that each gave off was incredibly profound. Not something just anyone could do. Yang Rai had bathed his Origin Essence Crystals in So Much source Qi and Emperor Qi that they had some… changes. Yeah, just a few changes.
"You have 81 Origin Essence Crystals?"
"No Mo Mei, look closer. These aren't normal Origin Essence Crystals."
"Brother how in the hell did you make 81 Crystals? You went from 1st order to 3rd order in like 5 minutes."
"I can't say for certain why but it was not an easy thing to accomplish. However Senior Yue He is correct, These were bathed in a never ending supply of bothe source Qi and Emperor Qi. Doing this tempered their foundations to near indestructibility. Recently I have been bathing them in World Force as well. Perks of my Artifact."
"This is simply unheard of. Yang Rai, I understand now why you didn't want to say that before. I would have had a hard time believing this."
"Master, who are these people?"
"Yin'er meet some of masters new friends."
"These friends are distracting masters. When are you going to bring more spirits here?"
"These people are going to help me with that."
"Oh, so they are good friends then. Yay, with their help we won't have to worry anymore."
"So as you can see I need to condense 81 Dao seals at once to truly become a Dao seal realm. However, I'm sure you have an Idea why that might be a bit difficult."
