All the Elders in My Sect Are My Avatars!

Common Summary:
A common modern man finds himself in an immortal cultivation world right after his death. Armed with a sect system to assist him on this difficult journey, he is shocked to discover that the elders summoned by the system are, in fact, avatars of himself.
Determined to take things one step at a time and enjoy his new life, he makes a decision: "I’ll leave the problems to my avatars, and I’ll cultivate in peace."

Xianxia Summary:
Are your cultivation techniques of high quality? Then check out the almost-perfect techniques my avatar created!
The best quality golden core is the extreme first-grade core? Then look at my extreme first-grade core!
The usual tribulation for geniuses has 9 lightning bolts? Mine does too! I don’t have a perfect foundation, so if the heavens send more lightning, I’ll sue them!
Common protagonists take an elixir that should make them rise 9 levels, but they only rise 1 because of their perfect foundation? Then I’ll take it and rise 10 realms, because my foundation is almost-perfect, not perfect.
Humph! While other protagonists struggle in one realm to reach perfection and fight a level higher, I’m already 4 realms ahead.

PS: There is no other protagonist besides the MC. In this summary, the protagonists mentioned are only from the works he read in the modern world.
PS2: I try to include explanations and descriptions of each realm and other aspects of the world, but they will only appear when the MC interacts with them or reaches that realm.
PS3: The avatars don’t have much focus in the beginning, but in later chapters, they will get more and more screen time.
PS4: Almost reaching the last console.
PS5: I made it!
