Throughout the journey, Lin Yi had not spent all his time cultivating, forging artifacts, and refining pills aboard the spirit boat.
Along the way, he passed through two temporary ship ports in the Tidal Spirit Sea, stopping briefly at each one.
Lin Yi acted cautiously. Each time, he merely blended into the crowds, quietly gathering information on the surrounding situation, local powers, and market prices, collecting only a little useful intelligence.
He never rashly ventured deeper, much less entered any complete Great World guarded by a Lord of a Realm.
The many worlds here were completely different from an open trade hub like the Fire God Great World.
The Fire God Great World valued inclusive trade. It did not question one's origins, restrict its visitors, or impose overly strict order.
But ordinary sovereign worlds of the Outer Realm had formidable barriers. Every heaven and earth ruled by a Lord of a Realm possessed absolute control.
The moment an emperor realm cultivator entered, they would inevitably be sensed and locked onto by the Lord of a Realm, with nowhere to hide.
Those Emperor Realm cultivators who had broken through using the World Containment Method might not be particularly outstanding in cultivation or combat strength among those of the same rank, but within their own world's territory, they were absolute rulers.
With the support of the World Origin, they were nearly omniscient and omnipotent. They could control the laws of heaven and earth, wield World Power, and multiply their combat strength severalfold.
Even cultivators far stronger than them would be constrained at every turn and fall into passivity if they rashly entered another's home ground.
Though Lin Yi was quite curious about the ecological structure and distribution of powers in these Outer Realm worlds, he would never recklessly put himself in danger.
