Unfortunately, Luo Si traveled through time and became a mecha warrior who was abandoned because his abilities were disabled.
Without money, no one loses face, and has to start an extremely difficult life in another world. Inadvertently, Luo Si accidentally "rescued" the mecha designer with disabled legs.
Luo Si (struggling): Anyway, I have cured your leg. Please let TAT go...
Long Jingyu (pressing it hard and licking his ears): There is no way to repay the kindness, and you don't want anything, so I have no choice but to pledge myself...
Luo Si's inner voice: It's wrong to save people with good intentions. I don't want to be pressured to let him go!
One sentence summary: Someone came and repaired the mecha together with the designer!
