Cultivating Immortality with My Elf Sister in a Different World

Japanese different world+sister+pure love+cool writing This is not how spiritual power is used. You should feel the spiritual power, then learn spells, and finally release powerful energy. After absorbing the spiritual power, you are said to have established a foundation. Sixteen years after being reincarnated into a different world, Renault secretly reached the middle stage of foundation building. No one in this world is a cultivator, and the magic power is frighteningly pure. He originally wanted to hide forever and live a low-key life with his elf sister, but his sister had to go to school and didn't have enough money to spend, so he took on dangerous tasks. His teammates asked him why he was so strong. He said he was "strong" and "lucky," but no one believed him and no one pressed him until one day, the devil woke up.
