Switched at Birth Twenty Years Ago, My Family Wants to Throw Me Away for the Impostor

In his previous life, Jiang Chen did not learn until he was thirty that he was an unlucky soul whose life had been switched with someone else's.

When his biological parents took him away from the desolate planet, they only had him tested for his talents. Once the results showed D-rank aptitude as a mecha soldier, C-rank command aptitude, and D-rank mecha engineering aptitude, his real parents never mentioned bringing him back into the family again. They simply raised him in their household. It was only after he was sent to the operating table, drained of his blood and deprived of a kidney, that he realized his parents had only kept him as a free organ donor for the impostor with A-rank aptitude.

Only after dying on the operating table did he discover that he had not been switched by accident, and that his aptitude was not merely D-rank! It was a rare SSS-rank! His malnutrition had only made it appear to be D-rank for the time being!

It turned out that a massive conspiracy lay hidden behind the impostor! During the decades he spent as a spirit, he studied every day and amassed an endless wealth of mecha knowledge.
