一个NPN2的mod，因为他突然下架不知踪影让人苦恼，而我巧合的保存着一份自己当时修改过的，所以放在了这里，很明显有人并不希望拥有它，那么现在它就是我的了。 A NPN2 mod that was suddenly taken down without a trace was distressing, and I coincidentally saved a copy of it that I had modified at the time, so I put it here. It's obvious that someone doesn't want to own it, so now it's mine.
