If the effect is +3, the Punk Dragon from the Dark Wings claims that if given a few female dragons, it can create a Dragon Race, which might not be just empty words.
At least in Lin Rui's understanding, a Giant Dragon producing 3-6 dragon eggs at once should be normal. With the +3 effect of the Royal Stable, a Giant Dragon can produce at least 6 dragon eggs at once.
Give it three female dragons, and it can reproduce about 20 offspring in one go.
With this effect, the Dragon God would have to personally come to Lin Rui with wine and meat in hand, to express gratitude for helping solve the dragon reproduction issue.
However, this issue is still far off. Firstly, Lin Rui doesn't have female dragons. Secondly, if the territory truly has over twenty Giant Dragons, providing enough food for them will still be a problem.
Can't have the neighbors store grain while I store guns, the neighbors would just become my granary.
