LitRPG: Once I Became A Master

When he transmigrated to this world of cultivation, he was extremely excited as he found out... that he had a System to help him!
He thought he would quickly become invincible under the heavens, but he found that the System didn't activate yet, and to activate it he received the task to write a few papers.
But who would have thought, even after five years of writing, he still wasn't able to activate the System and he was still that same little weak disciple of his sect.
He got frustrated and annoyed. He got furious and cursed at the System, but nothing helped.
Right when his Sect was in a situation so precarious that even the Sect Master had to get out and seek help, the System issued him a choice... Take over the position of Sect Master to activate it, or do nothing and the System would leave.
While everyone avoided this dangerous position, he didn't have any other option but to choose it! And it was exactly this very choice that marked the beginning of the rise of the most powerful Master to ever exist!!
