I Graduated from a Top University, but No Sect Is Willing to Accept Me?

Yao Qing worked hard for fifteen years and finally graduated from a top university with excellent results! The following is the step-by-step process of entering the Immortal Sect to work, get married, and have children. But things don't seem to be that simple... In the recruitment meeting for graduates, he was repeatedly ignored because of his excellent grades, and many resumes he submitted also came to nothing... With no income, he faces debt and an existential crisis. In desperation, he had no choice but to go to "Xianzong" to earn a meager reward. He thought his life was hopeless, but at a critical moment he obtained a "secret key to cause and effect". Before every major decision, he knew what cause and effect his choice would affect! Is the dynasty directly under the control of the sect or the sect in ruins? I choose the ruined sect! The daughter of the current emperor or a junior sister from a poor family? I choose junior sister from a humble family! Alive... Or dead...? This time, I choose death... (The story is a compact traditional fantasy. In the early stage, the protagonist mostly uses tactics to accumulate cultivation resources. In the middle stage, he becomes invincible on the same plane. In the later stage, there are constant big scenes.) Note: You will receive a brain as a gift when reading this book, and you will take it back after finishing the book!
