Yang Rai explored the entire star city looking for good places. He wanted to find places he could go with Lan Xun when she arrived. She had been planning on becoming a Great Emperor which was why she stayed behind. It was only right for Yang Rai to give her that chance, while also right for Lan Xun to allow Yang Rai the chance to discover things in the outer universe. Yang Rai was, after all, absolutely invincible within the Emperor Realm. So Lan Xun didn't need to worry about him.
The shops in the city were quite nice considering what Yang Rai was informed about the events before and after those idiots attacked. He stopped by a great many shops looking around. His goal is finding materials and nice things to give to Lan Xun. Something he learned was that materials need to suit the individual best. So he had to take into account a multitude of factors. Mainly the Bright Moon Ethereal Body she has. Resources with a calm and serene resonance with each other would be her best options. It didn't matter what rank of material they were since Yang Rai would do his best to have the element grow. He collected a ton of different resources and materials. On his trip through the star city. No information on the universe's four pillars or 12 columns yet. However the entire Void land knows at this point that those resources will bring them massive benefits if they can find them. Enough to the point it's not even worth them keeping the item.
The Protectors were very interested in Yang Rai's abilities. He could be considered a peerless Cultivator. However he will continue to struggle to reach the Dao seal realm. This is because no single universe world can come close to the needed heavenly way for him to advance into it. So he needs to condense it on his own. That alone is already far more difficult than with the aid of the heavenly way us the Universe Worlds. Moreover he must condense 81 of them at the Simultaneously. Even with his star Spirits aiding the process he not only didn't have enough energy but he also wasn't able to focus enough.
At first even the protectors thought he was just lazy for a moment. Then they realized that Yang Rai wasn't only younger but far more fierce than they thought. He was truly a heaven defying genius of unparalleled ability. He was already capable of forcing multiple 5th Rank OH realms into submission. With his own power alone. And even wield a strength that instantly activates an ability akin to a great defense array. Not to mention he can even refine low rank resources into mid ranks and potentially high rank resources.
Yang Rai found some things that had seemed interesting. He managed to find 4 resources that were related to moon strength. Sadly that was all. But he had spent too much time in the City already so he needed to go back and continue strengthening himself. Leaving the city behind he went to let the protectors know of his upcoming seclusion. They weren't surprised since that was mostly what he did. However Yue He gave Yang Rai a space ring.
"What's this for?"
"Some world fruits for your research. Yang Kai said to give them to you the next time we see you."
"I'll put them to good use."
