Watching Yang Feng leave complacently, Lu Xiaobu smiled.
This opportunistic master wasn't wrong; cross-border combat isn't as simple as just taking people and charging in!
People from small worlds coming to the great world need to reach the core to break through, and moving between different islands is similarly restricted!
The core acts like a registration office; only when registered on this island can one use their full strength.
Otherwise, strength will inexplicably drop by three levels.
After all, it's always said that after the Golden Core, cultivation is about one's connection with the world.
If you've been cultivating on one island, such connections will naturally be suppressed when you reach another, unless you become part of the new island!
Hence, for cross-border combat, without absolutely overwhelming combat power, one can only expand their island's core influence.
And to achieve the latter, only a Mahayana who has obtained core control can do so!
