I Use Science to Pretend to Be a Fairy

The protagonist is not an immortal and cannot cultivate immortality, but he uses science to pretend to be an immortal. He uses science to control swords and fly, and science to control thunder and draw thunder. If there are any similarities in reality, it is purely coincidental. I am a pure young man and will not conduct further research in this area. It is just my current opinion and some applied ideas on whether scientific cultivation of immortality counts as cultivation of immortality. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
