What Became of Me When I Was Struck by Lightning?

Lin Tian was struck by lightning. He was sent to the hospital for rescue and miraculously survived. Everyone said that surviving a catastrophe requires blessing, but Lin Tian didn't feel that he had any blessings. On the contrary, something happened to him that made his hair stand on end. Every night when night falls, his body becomes insubstantial, and then disappears from people's sight as if invisible. Moreover, his body seems to be insubstantial, and he can walk through closed doors or through walls... What frightened him even more was that he saw his grandfather, who had been dead for three years, standing in the graveyard at night waving to him. Missing his grandfather, he walked over subconsciously, and his grandfather hugged him tightly and cried, "My poor grandson, why are you here at such a young age..." After hearing this, Lin Tian was shocked. "I, what happened to me?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
