Suppose...
A train has been developing smoothly from the start of Doomsday to now, for a year and a half, it should be around level seventeen or eighteen, which means it will soon catch up with the first tier, reaching the purple zone or even the red zone.
It's very likely that in that area, he will be the only train.
All the mines and adventure maps are his.
Dig slowly!
But it feels unlikely, as many train leaders are rather stubborn, only focusing on the train level upgrades, ignoring those accessory levels, not caring about combat power, as that's not important!
Moreover, if like Er Dan, the short yet powerful train consumes fewer resources for upgrades, but must sacrifice many accessories, reducing combat power while still needing support from others.
If there's no support, such a short but powerful train would perish in a few days...
...
Outside the train car, everyone was busy.
Chen Mang was looking at the conditions for upgrading to an 8-level train.
