Chapter 739: Hundred Year Peak

Chen Fei's gaze shifted, sensing the unique fluctuations at the location of the tree demon's roots.

This was a Fourth-Tier superior secret realm. The tree demon thrived on its nutrients, relying on this secret realm for support. However, the tree demon's powerful nurturing abilities also made the environment within the secret realm even more conducive to growth.

There were also Fourth-Tier secret realms near Thousand Geese City; otherwise, Thousand Geese City wouldn't have been established there and stood for thousands of years.

Although it was only a Fourth-Tier lower-grade secret realm, it was entirely sufficient for Thousand Geese City. If the secret realm had been of a higher tier, Thousand Geese City's strength probably wouldn't have been enough to defend it.

Whether in the Boundless Sea or in the former Immortal Cloud City, matters among martial artists were straightforward: might made right.
