Before Lian Dai represented the Han Yang Empire in connecting with other Sea Clan factions and forming an alliance with the Contract Garden, she was already Fang Mu's protector and had established ties with Qixing.
However, because Lian Dai knew Fang Mu didn't want this information to be exposed, she refrained from disclosing it voluntarily.
Otherwise, with her relationship with Qixing, Lian Dai would have easily gained the upper hand in the collaboration, rather than being in such a passive position now.
This even forced Lian Dai to accept the Han Yang Empire's request to claim the space portal in the Sea of Domains as their own.
Upon reflection, Han Ming's actions of retaliation ironically set the stage for the later exploration of this Dimensional World.
Fang Mu's expression shifted when he heard this. Building a fortress around the portal in the Sea of Domains to isolate it from the outside world could maximize the safety of this portal.
