Proficiency in Cultivating Immortality: Add Points Starting from Time Traveling

Fifteen years ago, I fell from Southeast Asia into a parallel world as soon as I opened my eyes. The entertainment here is barren, without those familiar melodies and masterpieces. Just when I thought I could use my past life memories to kill everyone - a [Proficiency Cultivation System] hit me in the face. Write songs and play the piano? No, I will directly add some immortality to my skills! From [Basic Breathing Technique Lv. 1] To [Great Principle Lv. Max], from the corner of the campus to the top of the world. Everyone thinks that I am a funny genius who chases hot topics, but they don't know that behind every bit of laughter I have, my proficiency is beating coldly. In this life, I just want to cultivate immortality leisurely and play in the world. As for those figures who are moved by me? Sorry, my black heart only beats for immortality.
