My Scrap Left Hand

This is a world where steam machinery and crude magic coexist. Chen Nanfeng, who inherited his family's machine repair shop, had just learned how to change tires, but he forgot that he had just graduated from college and had not yet taken a driver's license, so when he got on the car to test the tires, he turned the accelerator to the full limit and died on the big tree at the door. He died after hanging up and traveling through time. However, the miraculous thing is that he can not only continue to observe the modern world, but also survive in this steam continent with a negative air index. He wanted to go home and continue repairing tires, so he decided to live well in this world, work hard to upgrade his studies, and find a way to return home. However, after he traveled through time, he only brought his useless body with him. In this world where prosthetic bodies filled his entire body, he could only transform one arm. The arm was just an arm, but it was trampled and broken by a monster just after crossing over. However, as a blessing in disguise, he installed a prosthetic leg that looked like scrap metal but contained an ancient mechanical soul. The mechanical soul taught him how to transform his arms and how to combine magic with machinery. So Chen Nanfeng looked at his steel left hand that was shining with mysterious light.

So he relied on this left hand to break through the underground mine and come to the above-ground world, break the boundaries between machinery and magic to establish a new research system, break the dimensional wall and look at the blue planet in the distance.
