Technology is the core of a civilization and a vital support for the development of a territory, benefitting the entire territory, affecting heroes, troops, buildings, and items in every aspect. Some civilization technologies can even unlock special troops, special buildings, or grant troops and heroes special skills.
For example, the "Firearms Manufacturing" technology that Xu Yang had unlocked through the blueprint, once the Yellow Turban Civilization acquired this technology, it directly unlocked the special building Yellow Heaven Gunpowder House, the special troop Yellow Turban Bombardier, and the distinctive item Sky Shattering Bomb.
That's the advantage of civilization technology.
But such technology isn't so easily obtained.
