"Rumble, rumble-"
The sound of many wheels turning at once came from a pit by the sea.
The pit's exit was behind a seaside hotel. The area above had already been sealed off, so ordinary people could not get in.
"Rumble, rumble-"
The sound of turning wheels drew closer.
Then,
"Whoosh-"
A [Minecart] emerged from the hole, carrying a sturdy young man with an oxygen tank on his back and exhaustion written all over his face.
"Whoosh, whoosh, whoosh-"
More [Minecarts] emerged from the pit.
There were twenty in all, each carrying an exhausted young man with an oxygen tank on his back.
Shen Jin came up in the last [Minecart], all smiles.
"Good! It's finally finished. The undersea mine three thousand meters down is ready. Next... we reap the rewards!"
Over the past week, Shen Jin's main priority had been digging the deep-sea mine.
He had led twenty ordinary people in digging from this hole, advancing toward the deep sea step by step. Along the way, they had installed [Rails], [Powered Rails], and [CUSE Energy Storage Units] to supply power, allowing everyone to travel up and down to the undersea mine.
At around eight hundred meters below the sea, these ordinary people had begun to feel oppressed and struggle to breathe.
Shen Jin had gotten twenty oxygen tanks from Old Fu for them to wear before they could continue working.
Many minor accidents had occurred along the way, but with Shen Jin's current formidable strength, every crisis had been successfully resolved.
The most dangerous had been a sand collapse. Before they could build the support pillars, all the clay and sand above them had collapsed.
Shen Jin had given everyone Giant Sausages to eat, and with Tier 1 Peak strength, the twenty ordinary people had avoided being swept away
