The World of Cultivating Immortals Comes with a Strategy System

Wang Lisen, an ordinary young man from Earth Star, accidentally traveled to the world of immortality while playing a game. I accidentally discovered that I traveled through time with the game's system. "I heard that this old man from the library is difficult to get along with." Let me see if he has a mission. "What? You only need to chat with him for three minutes every day, and your favorability will be +5. Your favorability will be raised to three stars, and you will also be taught a top-notch swordsmanship?" Don't stop me. I want to talk to the master for three days and three nights.
