For one, many spirit beasts had the habit of moving at night, and it was easy to encounter them if they moved at this time. Secondly, their perception was blocked at night, so even if there was danger, it was difficult to detect it, and it was easy to run into an iron plate.
However, this wasn't a problem for Lin Yi. His spirit sense was enough to sense anything, and as long as it wasn't voluntary, he was 100% sure that he could avoid all dangers. Of course, with his situation, there probably weren't any real dangers in the entire ancient martial world, and he could do whatever he wanted.
Lin Yi didn't have the hobby of imitating crabs-as long as they didn't go in big circles, he'd take the initiative to go around the spirit beasts blocking their way. With a guy like him who'd almost opened up the map leading the way, the group's journey was naturally smooth.
