Immortality: My Spell Upgrades Infinitely

Yesterday was fine, but the scholar had symptoms when he woke up in the morning. His head was buzzing, his whole body was weak, his legs were shaking, sore and painful. It was so uncomfortable that he couldn't sit still (crying loudly). I owe you a chapter first. I'll see if I can make it up tomorrow. Don't wait any longer. Take care of yourself and go to bed early~~
