Pondering, Brian's ears twitched, and he suddenly looked to the north.
Soon after, several helicopters flew over his head.
These helicopters were flying slowly, equipped with loudspeakers, continuously warning the campers and sightseers in the park, announcing that terrorists armed with heavy weapons had infiltrated the national park. For safety, they were instructed to leave the national park as quickly as possible.
Brian realized his opportunity had come.
He quickly packed up the camping supplies he had prepared in advance, found a hiding spot to stash them, and then reverted to the guise of Yagyuu Kojirou. Following his memory of where the base was hidden, he arrived at a canyon cliff near the edge of the national park.
The entrance to the base was located at the bottom of the cliff.
An animal research institute was established there as a cover.
