What is the difference between the Three Kingdoms No.10 Middle School Weapons Development Institute, Weapons Manufacturing Institute and Technology Research and Development Institute? Is it necessary to have a weapons factory to build weapons?
The weapon development institute is the weapon manufacturing institute, which can manufacture weapons, such as washing cars and well sites (technology is greater than 1800). If the city has a science and technology development institute, it can manufacture more advanced weapons, such as wooden beasts (full of science and technology) and wooden cows (raising the upper limit of carrying soldiers' food). I remember Jiangzhou has a technology development institute in addition to the weapons manufacturing institute. Similarly, cities with infantry establishment, Gong Bing establishment and cavalry establishment all have science and technology development colleges, and they can also upgrade the highest-level arms (Guards, Rong Yuan Archers, Tiger and Leopard Riders). There is no institute of science and technology development, only cities with infantry, Gong Bing and cavalry can only be upgraded to (heavy infantry, crossbowmen and heavy cavalry).
In a word, the technology development institute is linked to the most advanced arms weapons, and weapons can only be manufactured in cities with weapons manufacturing institutes.
When you have it, you should adopt it step by step.
