And if none of the skills were ever propagated, should this sect be exterminated one day, I'm afraid not even a trace would be found.
In that respect, propagating some of the non-core skills naturally isn't all bad for these sects.
Some sects even deliberately propagate their internal skills.
Just like the Thick Earth Sect where He Song had stayed before.
Within the area of influence of the Thick Earth Sect, whether it was the cultivation skills or the secret skills of the Thick Earth Sect, they were all clearly priced.
That way, even if the Thick Earth Sect were extinguished one day, the cultivators who had learned these skills and secrets could hardly be eradicated.
If one day someone steps into the Golden Core and wants to occupy the territory originally belonging to the Thick Earth Sect.
Perhaps they would directly choose the name of the Thick Earth Sect.
