Upgrading to a Level 11 train requires consuming 2 million units of iron ore, upgrading to a Level 12 train requires consuming 3 million units of iron ore.
Here, 5 million units of iron ore are gone.
Another 6.75 million units of iron ore were consumed to upgrade the Level 9 armor to Level 14 in one go.
A total of 11.75 million units of iron ore were consumed.
"Alright."
Standing aside, Chen Mang patted Er Dan on the shoulder: "A Level 12 train with Level 14 armor should suffice even in a purple area. Probably not many people in the purple area have Level 14 armor; is that batch of 1 million iron ore I gave you last time still sufficient?"
"Enough, sufficient." Er Dan quickly nodded: "I just use the iron ore to manufacture some food and Energy Stones, and there's not much consumption, it's enough."
"Alright, then get on the train. We'll split into two groups once we enter the purple area later."
"Yes!"
