The man tells me to get out: this is his territory and he will defend it to the death!

But as I get close we recognise each other - this is a soldier I met earlier. He relaxes and we talk. He says the Martians have a flying machine, and it's all over for humans. We are like ants to them. But this old soldier plans to fight back. He will find people to live underground and scavenge for food. They will study science and start the human race all over again.

He says I can't stay, he only wants people who are tough enough to survive on their own. So should I travel east? Or should I travel west? Or do something else?
