Ancestor of the Sect: After My Rebirth, I Just Want to Keep a Low Profile!

I, Lin Xuan, was once the Nine Heavens Immortal Emperor. I destroyed all realms with one sword, but fell in the thunder catastrophe of ascension. After my rebirth, I became the ancestor of the Qingyun Sect who was about to pass away. The sect only had three disciples and half a spiritual mountain left. While others are reborn and cheating to dominate, I just want to keep a low profile: sign in to get fragments of heaven, train disciples to become saints, and secretly lay out the plan for ten thousand years... When the old enemy came to kill me, I slowly opened my eyes: "Qingyun Sect, from today onwards, we will dominate the nine realms!" (Low-key Taoism + sect cultivation + master-disciple bond + long-term conspiracy, Zero Dragon Aotian, pure starting point flavor!)
