the place, but a head-on fight...
I thought that was impossible.
In this apocalypse, the less you experienced, the less you gained.
I thought... if we brought the people from XZ Military Region out and compared them with survivors from other regions,
the average strength of the two groups would show XZ Military Region being completely outmatched.
That was probably why, after humans evolved brains and learned to use tools, their physical fitness gradually declined.
Modern people's average physical fitness really was declining. The most important reason was that the brain thought... there was no longer any need to send
extra energy to the body, and instead,
more of it went to the immune system.
Humans gradually gave up the ability to do physical labor in exchange for eating crops covered in pesticides and
food containing lean-meat agents and all kinds of additives. As a result, the body's evo-
lution pushed it to improve its immunity so it could adapt to these foods and certain medicines.
So it was only natural that humans' physical fitness would decline, and that they would live longer, because their immune systems were growing stronger.
As for XZ Military Region, it was like modern people, while the survivors outside were like people from ancient times.
But the virus had greatly accelerated the pace of evolution, which meant there was bound to be a huge gap between the two sides. That gap
came down to the difference in how much exercise they got.
The difference in exercise had changed how the virus drove their evolution.
It had compressed thousands of years into just a few years, or even a few months.
You could call that a kind of natural selection, couldn't you?
In my eyes, these two men really weren't as physically fit as Zhang Min
