Xuanhuan: Experience Returns, and From the Start I Take an Emperor as My Disciple

The Protagonist Reaches the Saint Realm and Becomes the Sect's Youngest Elder, Then Returns Home to Deal with a Family Crisis

I forgot the title. The protagonist reaches the Sage Realm and becomes the sect's youngest elder, then returns home because his family is in crisis. I think his surname is Su.

Any Novels Where the Protagonist Is Invincible and Takes Disciples Everywhere?

The protagonist is invincible and goes around taking on disciples.

The Protagonist Gets Stronger by Taking on Disciples, with No Romantic Subplots

[Most important: no female lead! No romantic pairing! No ambiguity!] Ideally, the protagonist has limited aptitude and cannot reach a higher level, so they use a System to recruit talented disciples and then become stronger. It's fine if this isn't included.

Looking for a Story Where the Protagonist Activates a Master System and Gets Rewards by Taking Disciples

Any Stories About Taking on Disciples?

For example, My Disciples Are All Big Villains.

He Kept a Low Profile and Avoided Trouble, Taking in a Bunch of Disciples. When They Died, He Flew Into a Rage and Came Out of Seclusion.

The protagonist has a bunch of disciples but stays holed up at the sect. After the disciples die, he flies into a rage and leaves the mountain.

Already Invincible, He Gets Cultivation Rewards from Daily System Sign-Ins, and the System Assigns Him Discipleship Quests

For reference, My Disciples Are All Destined to Become Emperors. Please recommend novels where the main plot follows the disciples growing stronger, and the protagonist shows up to save the day at critical moments. Does anything like that exist? (The protagonist has no restrictions and is invincible against everyone.)
