People generally believe that entering the Immortal Sect is like securing a lifetime job.
This statement is largely correct.
After entering the Immortal Sect, whether you are in the Outer Sect or the Inner Sect, as long as you do not create trouble or violate the Sect rules, even if you are not ambitious, you would not be expelled - at most, you would either be transferred elsewhere or maintain your current position.
However, for cultivators in the Immortal Sect who are ambitious, the pressure from the Sect is quite significant.
Since He's family is in the Capital and her performance was average when she tested into the Outer Sect, she couldn't secure a position in the highly competitive Capital. She had to be dispatched to Wuyue City instead.
If she wanted to return home, she had to achieve some results to be transferred back to the Capital.
And, as it happened, her recent performance was very impressive.
