Everyone knows that Ancient Tomb sect was set up by LCY. We all know that the leadership was then passed on to XLN. Afterwards, we haven't heard of this sect again until the presentation of Yellow Girl in HSDS. This Yellow Girl can be either the grandchild of Yeung Gor or, perhaps, the leader of Ancient Tomb sect at the time. In HSDS 1986, Yellow girl presents herself with some followers, it might be able to assume that Ancient Tomb does exist at the time of HSDS as some forms of groups or sects. But, what happen to it after the end of HSDS? If it does exist, it should not be worse than, say, Er Mei at the time. If Er Mei continues to exist after HSDS, why Ancient Tomb did not exist?
