Among the Level 2 train components, "armor" and "Wind-Fire Wheel" are arguably the most expensive. The Wind-Fire Wheel is relatively okay; upgrading from Level 1 to Level 2 requires consuming 1000 units of iron ore, and each subsequent upgrade consumes 1000 more units of iron ore.
As for "armor," he couldn't be bothered to mention it.
Upgrading from Level 1 to Level 2 requires 5,000 units of iron ore; from Level 2 to Level 3, it requires 10,000 units of iron ore.
Without finding Level 4 iron ore, he hadn't even considered Level 10 armor.
A Level 5 Wind-Fire Wheel is sufficient.
His speed is already quite fast, so there's no need to go faster.

After glancing past the "Wind-Fire Wheel" component, Chen Mang looked at other components.
Many components actually don't need upgrading for now, such as the "single bed" and the "Pure Water Filter." It's better to focus on improving defense and attack first.
After pondering for a while.
