Lin Fan just checked out a few more things with the system before leaving the store.
Momonga wasn't planning on leaving, so Lin Fan just left the store to him while heading back to the palace.
Angela, Yuki, and Zi Ling had gone out to eat, so for once, it was just him alone.
However, there was no danger to him at all since he had guards from the Lin Astral Family with him.
The captain of his guard team was someone in the Peak Planet Realm with a Ruler Artifact. Unless there was an actual Ruler Expert that invaded the Lin Astral Empire, it was impossible for anyone to hurt Lin Fan.
If there actually was a Ruler Expert that invaded, they would be immediately stopped by the Lin Astral Emperor and the other Ruler Experts in the palace. It wasn't as if Lin Fan was that far away from the palace in the first place.
However, since this was his first time being alone, many people thought that this was their opportunity to approach him.
