The Lu family members worked as car mechanics for generations but they only became well-known because of Lu Huai's father. His father not only knew how to repair cars, but also manufacture parts and design improvements for cars. Everyone addressed his father as "Master Lu".
In the capital, if his father claimed to be the second-best mechanic, no one would dare to take the top spot. Everyone thought that Lu Huai's father would have clever and outstanding children, but Lu Huai's elder brother turned out to be a simple-minded person who did not like to study. As for Lu Huai, he was very rebellious since he was young and always went against his father's wishes.
Things changed during the year when Lu Huai's father lost his life in an accident. At that time, Lu Huai was only 16 years old and his elder brother had run away from home. As the only man left in the family, he had to buck up and be strong.
