Chu Hongjian, a third-rate mechanical engineer who was not doing well in China, was lured to the African continent by a high-paying contract called "African Technical Assistance". I thought I was a technical consultant who was here to be a master, but I found myself thrown into a poor and helpless tribe. I faced a desperate life of lack of water, electricity, and food every day. Just when he thought he was going to die in a foreign country, an "inventor system" was accidentally activated. There is no magic that can destroy the world, and there is no magical skill that can reach the sky in one step. This system only provides technological blueprints based on reality, and everything needs to be created by his own hands using the most primitive waste products. In order to survive, and for the pitiful points reward, Chu Hongjian was forced to roll up his sleeves, starting with a simple water purifier, and gradually embarked on the road of "King of Invention" on the red soil of Africa. What he has to face is not only the harsh natural environment and scarce resources, but also the suspicion of local people, the covetousness of surrounding forces, and one thorny technical problem after another.
