Though setting up a production line is quite troublesome and requires a lot of expertise, fortunately the professional matters are handled by professionals. Chen Xin only needs to submit the blueprints for the Isotope Thermoelectric Battery and specify the required materials. The relevant production line will naturally be planned by specialists.
Chen Xin originally intended to design the production line himself, but while he was confirming the site conditions with the construction staff at the small shelter, the special team dedicated to collaborating with him had already sent over the drafted design through military fiber optic lines, and it was even printed.
This is not to say the country is so impressive that a design can be made in such a short time. Even if the designers were driven bald, they wouldn't be able to deliver. It's not a matter of determining a plan, but simply that finishing a drawing can't be done in such a short time.
