From Being Born in a Demon Sect to Being the Leader of the Righteous Path

Reborn in the world of immortality, but with a system. As long as the sect is not destroyed, I will not be destroyed, but it is difficult to leave the scope of the sect, but the sect can fly. The stronger my disciples are, the stronger I am, but I don't have any disciples. You can travel to other planes, but your ability to cultivate immortality is disabled. There is a technology tree, but it can only be researched by disciples. Having cultivated immortality as the core framework, Mo Yao used products from various planes to patch things up, and finally built the demon sect he was born into into the most powerful righteous sect.
