Rebirth Of Military Industrial Children

After the Industrial Revolution, European Science And Technology took hundreds of years to develop, but New China was founded in just a few decades. In the general technology industry, we need to catch up; in high-precision and cutting-edge fields, we need to overtake in corners.
As a technician who has worked in the military industry for decades, Xie Kai was reborn and returned to the day that changed his life and that of many people.
In this life, he does not intend to accept his fate anymore, but uses his knowledge to change the fate of those around him. It is also this change that allows the Republic of China's military industry to achieve roundabout overtaking in some fields in advance, and also catch up with the European powers in most fields.
Tank? Rocket launcher? missile? Advanced fighter? Nuclear submarine? Aircraft carrier? It has nothing to do with Xie Kai...
Foreign technology blockade? embargo? It's okay, let's find a way...
Want Chinese weapons and equipment? This matter... is easy to discuss even if you have money...
What does Xie Kai do? He couldn't even figure it out himself. He only remembered that he was a military worker!
