Zhou Wanlin paused slightly and continued:
"Look, the five cargo boxes are '1, 2, 6, 7, 12,' and each round of the game allows 26 minutes of transport time.
"Even if you use the slowest method, transporting one and a half rounds, you'll definitely carry more than this.
"Cargo boxes 1 and 12 go forward, box 1 comes back, then boxes 6 and 7 go forward.
"This is 12+1+7, using only 20 minutes, yet you transport 12+6+7=25 units of goods, sending half for inspection equals 13 units.
"10 units is too few, there's only one possibility.
"Box 7 and box 12 go forward and end.
"This counts as 19 units of raw material, halving gives 10 units.
"But transporting like this, he actually only used 12 minutes.
"What did he do with the remaining 14 minutes? Why didn't he continue transporting?"
Huang Shengjie's eyes widened instantly: "Are you saying... during those 14 minutes, he wasn't at the miniature train but went somewhere else?
