In the Fireworks Factory at the Beginning, What I Built Is Really Not a Missile.

Chen Xin traveled to the 1990s and became the director of a fireworks factory. At that time, the fireworks factory was not performing well and was about to go bankrupt. More than a hundred people in the factory looked at him eagerly. He was having a headache when the [Universal Intelligence System] came. Chen Xin rubs his hands and manages to live a well-off life. It will be alright, right? But the style of painting is becoming more and more biased. I tried making firecrackers and they exploded directly through the rocks. People in the factory said that the materials used were too strong!​ Developed rotating fireworks, and also made Nezha's Hot Wheels!​ He did a double kick and flew two miles away with tail flames. The people shouted that they had seen the "east wind"! Finally, one day, a man in a green military uniform came to visit. "Director Chen, we are considering incorporating your fireworks factory into a military factory."
