Immortality and Immortality Start from Naturalization in Shushan

[Swordsmanship + fantasy fairy + mortal cultivation + single female protagonist + no system + steady and cautious + decisive killing] My name is Chu Chen, I was the top scorer in high school at the age of twenty, but my family was destroyed by an immortal. Forty years, knocking on the gate of immortality for forty years. At the age of sixty, he was taken back to Shushan by the empress to cultivate immortality. A slow-paced and enjoyable story about cultivating immortality. The process is cyclical and gradual. It is not brainless. The protagonist has the brains. Fellow Taoists, please don't be dissuaded from the beginning.
