Chen Du, a social animal who had not been ashore for three years in the modern examination, died suddenly and traveled to the world of immortality. He became a scattered cultivator who was about to expire and faced the risk of being abandoned.
He discovered that the world relied on "immortal exams" to allocate cultivation resources and determine class, so he adapted the modern exam-taking methodology and took the exam from a casual cultivator all the way to the heavenly establishment.
It wasn't until he touched "above the establishment" that he discovered that the entire establishment system was a harvesting machine. In the end, he did not establish a "fairer promotion system", but dismantled the binding of "survival rights, cultivation rights and establishment".
