"Traveling Frog": "It's not very hidden, there's another train mining Level 3 iron ore right next to it."
"Fixed Star": "...You mean he's ignoring the Level 4 ore and mining Level 3 ore instead?"
"Traveling Frog": "Yeah, but that train is now forcefully private messaging me to leave immediately."
"Fixed Star": "Got it, continue with what you were doing."

Chen Mang narrowed his eyes slightly, withdrawing his gaze from the Train Radio. He suddenly remembered something from when he was in the Zombie Basin and encountered an opportunity— a safe buried underground.
Inside was a Level 4 "Red Heart Rock" Mine Refresh Coupon and a blue-grade Mecha Blueprint "Thunderbolt".
These two opportunities allowed the train to achieve mecha freedom for a long time, never lacking Red Heart Rock, and to this day, it hasn't run out.
He didn't think much of it at the time.
He thought that these two things were a set.
Ensuring the train wouldn't lack materials for building mechas.
