Lu Ci, a mechanical engineer, woke up and the world changed. The solar storm destroyed integrated circuits around the world, smartphones turned into bricks, AI-controlled unmanned cities turned into steel graveyards, and human civilization regressed back to the steam age overnight. Good news: He is a mechanical engineer with maximum hands-on ability, and he has countless drawings in his mind, from steam engines to internal combustion engines. Bad news: He is physically weak and has no strength in his hands. In this wasteland where fists speak, knowledge sounds like... It doesn't have much weight? While others were fighting for the cans, Lu Ci was silently calculating the data of the wind turbine in the corner. While others were fighting the mutated creatures with wooden sticks, Lu Ci drove away in a small four-wheeled car he assembled. While other survivor bases were still fighting for a clean water source, Lu Ci had already built a simple water purification circulation system and began to think about how to improve the flushing efficiency of the toilet. A certain muscular leader (disdainful): "What's the use of your tinkling scrap metal? Can it be eaten?" Later, he took the survivors of the entire base, holding the most precious mutant beast crystal core, just to ask Lu Ci to help them repair the water pump that was related to everyone's life. "Road worker, Master Lu! How do you think this gear should be ground?" Lu Ci pushed up his self-made flat glasses and said slowly, "Knowledge is power, my friend. Besides, this is another price." Small Theater: At first, the scavenging team that picked up Lu Ci just wanted to find an educated person to keep accounts. Later, this frail young man became the most sought-after treasure in the entire wasteland.
