To Build a Mecha, My Little Junior Sister Is Forced to Cultivate Immortality

[Mecha Engineer + Absurd Comedy + Ensemble Cast + No Romance]

While everyone else in the immortal sect is working hard at cultivation, I'm scavenging junk to build a mecha.

Jiang Yu wakes from a dream to find herself transmigrated to another world, where the mecha she depended on for survival is gone. To escape her frail body, return to the Alliance, and become a genius mecha engineer, she has no choice but to embark on a long journey of scavenging and cobbling together a mecha.

Body cultivator, leave those exotic beast bones at your feet! Sword cultivator, don't throw away that whetstone you don't need! If I put it all together, surely it'll work.

But how did I end up becoming an immortal without even noticing?

This is a story about an immortal sect rising to prominence, and a group of youngsters who swindle and cheat their way... ahem, to the pinnacle of life.
