I Ask You to Repair a Broken Car, and You Make a Mecha for Your Daughter.

"Sign it. Your monthly salary is three thousand, and you can't even afford a toilet in the school district room. How can you raise your daughter?" The ex-wife's current leather shoes mercilessly crushed her daughter's treasured old music box, and dumped the custody change agreement on a car repair bench full of engine oil. In despair, Lin Chen awakened "absolute muscle memory"! He silently picked up the scrap gears and knives on the ground, his hands turning into afterimages. Ten minutes later, an aerospace-grade mechanical music box with gear meshing accuracy reaching micron level was born with bare hands! The retired chief engineer of the military industry who happened to be passing by was so jealous that he offered a million dollars in cash and begged for it! The current rich man was still mocking Lin Chen for being a repairman of broken cars, but he turned around and faced bankruptcy because he could not produce qualified military parts. Until he saw the military helicopter landing in front of the car repair shop, and the academician of the National Academy of Sciences respectfully handed over the top secret drawings... His ex-wife regretted it on the spot and turned blue in her intestines! "Dad, I want to see Transformers!" "Okay, daddy will give you a real mecha!"
