吸血鬼伯爵科技购买 Vampire Earl Technology purchase

这个mod为吸血鬼伯爵派系增加了额外科技购买。
This mod adds additional tech purchases to the Vampire Earl faction.

注意：如果度过回合时你的财政不足以支付科研费用那么就无法继续研发哦。
Note: If you don't have enough money to cover your research expenses during the round, you won't be able to continue research.
我的mod只能同时开启一个，请玩啥派系用哪一个mod不然会冲突。
