[Interstellar] + [Mecha] + [System] + [No High-Level Martial Arts]
(Author's note: Mecha are just mecha. No cultivation stuff.)
“Boss, take a look at my mecha... Can you fix it?”
“Of course. Eight million. Come pick it up in a week.”
“Sorry, I need to use this mecha tonight.”
“Oh, no problem. Since there's not enough time for repairs, I'll just upgrade it for you. Twenty-four million. Come back in seven hours.”
“...Huh?!”
After transmigrating to a future Interstellar world, Yang Yi became the scion of a powerful family. He planned to live carefree as a pampered young master under his family's protection for the rest of his life. But not long after starting middle school, his family was wiped out in an instant. With the help of another family's guards, he barely escaped with his life and was sent to a remote star system far from the heart of the empire, where he took up work as a mecha mechanic.
Just as he was feeling lost, the System that had appeared when he first transmigrated, but had remained silent ever since, suddenly activated and gave him the means to rise again.
Mecha nobody else can fix? I'll fix them!
Mecha nobody else can upgrade? I'll upgrade them!
Mecha repairs others can handle? I can handle those too!
Mecha repairs others can't handle? Then I'll handle those as well!
But just as he planned to use the System to keep living carefree in this remote star system, he found himself constantly caught up in one problem after another, forcing him to grow stronger and face them head-on. In the end, Yang Yi, who had only wanted to live a quiet, easy life, was driven onto the path to becoming a legendary mecha mechanic...
It feels like the protagonist is a puppet, but that was no longer the case after the later system was directly invented.
It's fine without cultivation, but there are no various potions to strengthen the human body. Is this the interstellar age?
