During the flight of over ten hours, the in-flight crew arranged breakfast, lunch, and an afternoon tea. Additionally, at the hotel in Bermuda, dinner had already been arranged. It's just that Lu Xuanyu's situation is a bit special. Many ingredients specifically for Benchmark Man cannot be exported as 'fresh food' beyond the national border.
Theoretically, all metal-based organisms will never be able to gain a foothold on Earth, unable to compete with Earth-native organisms. Even throwing metal-based mammals back to the Carboniferous period, they might be eliminated by the giant insects and primitive vertebrates of that era—the body functions needed to dominate Earth, plus the unimaginably evolved skills of Carboniferous animals, can't offset the energy loss brought by 'body temperature requirements'.
Only a species like humans, who understand energy conversion and have an excess of productivity, can fully realize the capabilities of benchmark gene modification.
