Time travel + farming + industrial revolution + struggle for hegemony.
Lu Chen, a top student in science and engineering, drove to Tibet in a RV and stepped on the accelerator into ancient times.
When I woke up, the RV was stuck in a ravine, surrounded by refugees fleeing the famine. Hundreds of people were so hungry that they gnawed the bark of trees, and the officers and soldiers were still chasing after them. Lu Chen opened the locker - mineral water, compressed biscuits, military cans, endless supplies. What's even more outrageous is that the supplies are automatically replenished every early morning.
He took the refugees to find a mountain valley surrounded by mountains and built Taoyuan Village. Plant potatoes, smelt steel, build muskets, pull barbed wire. The bandits come and use grenades to teach you how to be a good person, and the officers and soldiers come and load guns to teach you how to be a good person. From a few hundred refugees to tens of thousands of soldiers, from not having a single knife to an array of steel guns and cannons.
The world was unified, and Lu Chen was not called the emperor, but only the "general manager". He promoted the industrial revolution: steam engines, railways, telegraphs, electric lights, automobiles... Technological processes were hundreds of years ahead of schedule. The country of China became the most powerful in the world, and all the countries came to visit.
However, when he was at his most glorious, the RV took him and disappeared mysteriously. Civil strife broke out, and Western coalition forces took advantage of the situation and moved in. The white light flashes again, the king returns, and he brings more advanced technology!
