Rebirth 90: My Private Enterprise Turned into an Arms Research and Development Center!

After time travel, Zhang Yi, who had experienced death, knew that he was a time traveler. In order to avoid unnecessary trouble, in this life he wanted to run his revitalizing firecracker factory safely and quietly deliver technology to the motherland from behind. However, the gunpowder developed by himself made the Chinese strategic department's eyelids jump and their hair stand on end. It broke into the sight of the Chinese high-level officials at the beginning. Without saying a word, they bought out the formula at a high price of tens of millions! With a huge sum of money in hand, Zhang Yi thought that he could make a big splash this time and take over a steelmaking plant. Ordinary steel was improved and became special steel that China urgently needed. Representatives from China came to visit again, but unexpectedly discovered that the air cooling system of the slag turned out to be a prototype of a turbofan engine. The two technology patents were quickly acquired again. Zhang Yi, who has become wealthy and free, said: OK, in this life, the motherland will be prosperous and strong, and I will be considered accomplished and retired. From now on, I can go fishing and lie down comfortably! As a result, within a few days of playing with the fishing rod he made, he was surrounded by a special team with loaded guns and ammunition by the river! Reason? The special carbon fiber and winding technology used in his fishing rods allow the Air Force to see the dawn of the next generation of ultra-light and high-strength composite materials... "Comrade Zhang Yi, stop fussing!" The national security personnel looked at this genius with a crooked civilian technology in front of them, their eyes expected! "Let's either join a staff!" As the "industrial bottom-up" at the national level unfolds, Zhang Yi's seemingly unremarkable civilian companies and technical reserves have made the originally out-of-reach "Thousand Hands Project" drawings gradually change from "impossible" in the eyes of experts to a resounding four-word "I think it can work!"
