บท 182: Chapter 178: Cut-off Score_1

```

Thanks to the solid foundation of the B+-level system, Guo Shen quickly came up with a fast and stable solution:

"Place an H80 engine between the four slightly separated H240 engines. Normally, it is shielded by the four larger nozzles and cannot start. During recovery, the four H240s spread out to their maximum, then the 80-ton class hydrolox engine H80 starts up and carries out the recovery procedure."

After sketching a few strokes on the tablet equipped with X32035 that he carried with him, a viable plan was presented in front of Lin Ju, who nodded in satisfaction:

"How long will it take to modify this second stage?"

"It can be used the month after next. The changes are minor. We have manufactured six second stages; two were used for the axial cabin segments of the March craft and have no time for retrofitting, but the rest can be modified."

"What's this?"

A voice popped up beside them, followed by Big Shot's graying hair peeking over.
