Who are the four ancestors of Xuan Ming?

Xuan Ming's four great ancestors were: mutilated corpses (surrender), blood-stained rivers and mountains (Hou Qing), bare land (welding) and bottomless sea (firefly hook).

These four men were once masters of Xuan Ming, all of whom were profound and mysterious. At present, there are only two, one is Hou Qing, and the other is the welding needle discovered by Hou Qing. The remaining two have never appeared, so there is a lot of speculation.

The most powerful corpse ancestor:

And the strongest fighting capacity also exists, not Hou Qing, nor Hiderigami, but the last ancestor, which is said to be the most serious ancestor. Because he has cultivated all the plots of Nine Xuantian, his strength must be the strongest. At present, it is basically a bald image, but I don't know whether it is handsome or not. If he doesn't want the role, that's great. He will also play in the sixth season.

It is inevitable that the four ancestors will get together, which is also the picture that the government wants to create, but they are together again, which is estimated to have declared a tragedy. After all, the plot of the sixth season is the most tragic.
