It's Useless, I Woke up into a Puddle of Moss and a Silkworm

Twenty years after the spiritual energy was revived, others awakened to control fire and thunder. What about me? There was a puddle of moss in the unfinished building, plus a silkworm that was eating me. When Su Tang found me, she asked me if I could tie someone up for her. I said I didn't even have any hands. She said: "Your silkworms have silk."
