After Mr. Liang had eaten the "last hamburger" and left Australia with Xiang Kun to return to East Asia, he instinctively had a different expectation of the "last station" mentioned by Xiang Kun.
Throughout the "Hunting Trip" with Xiang Kun, many of the "Blood-eating Creatures" they encountered possessed formidable fighting power. If he were to face them alone, ignoring the hardest part of locating and confirming the creatures' whereabouts, he could probably handle it if he had the appropriate "Biological Components". Regardless, it would still be a challenging endeavor—for instance, he could not have disposed of that water-based behemoth as easily as Xiang Kun had.
